Common Faults and Treatment Methods in the Operation of Garbage Incinerator Grate

This chapter makes a deep analysis of the common faults and some minor problems in waste incinerators, thoroughly investigates the root causes of the problems, does not ignore the details that may occur at any point, and adopts a series of solutions according to the problems that arise, and puts forward numerous suggestions for operation technologies in the process of operation, so as to facilitate the normal operation of waste incinerators and obtain significant economic income without harming the environment and social development.

I. Factors Affecting Waste Incineration
The residence time of household waste in the incinerator, the temperature of the incinerator, the turbulence and pre-treatment of waste are the main factors affecting waste incineration, among which the residence time of waste in the incinerator is a vital step, only reasonable and careful adjustment of the residence time of waste in the incinerator and the flue gas in the incinerator, minimize the generation of secondary pollutants, safe and stable combustion of waste, minimizing pollution is the ultimate goal of the state and the incinerator personnel.

Kiln combustion control and frequently asked questions 1. Pusher failure If the pusher is triggered, it will affect the specific operating conditions of the kiln. Pusher failure is generally divided into three kinds, firstly, the pusher synchronization failure, secondly, the abnormal action of the pusher, thirdly, the mechanical failure of the pusher, because the displacement speed of the left and right sides of the pusher is different and very different, resulting in inaccurate pushing timing, coupled with uncertain understanding, synchronous motor wear, proportional directional valve jamming and proportional amplifier fault are the main reasons, affecting the abnormal action of the pusher, the guide wheel falling out, the general position of the pusher displacement, etc. This is the cause of mechanical failure, and excessive debris moisture, resistance will also affect the normal operation of the pusher.

2. Grate failure
The failure of the drainage furnace is also a key factor affecting the normal operation of the incinerator, its failure is also mainly manifested in three aspects, the first is that the drainage furnace is easy to advance and not easy to retreat due to the thick material or the problem of the limit switch. The second is the failure of the drainage furnace to move due to the jamming of the proportional directional valve. Third, the drainage furnace cannot move due to the failure of the hydraulic system.

3. Garbage feeding problem
The garbage feeding time is not accurate, loose garbage is not handled correctly, it is re-captured, the residence time is shortened, which leads to excessive garbage in the furnace, these problems greatly affect the dry section incineration operation, delay the combustion time of the garbage, which leads to unstable furnace temperature, and the furnace also fails from time to time because the garbage accumulates, compacts during the trip, the sluice is blocked, a bridging situation occurs. This affects the correct control of the furnace temperature by personnel and is very susceptible to failures in the feeding process and the stationary state of the Katon pusher.

4. The problem of the main pump of the hydraulic system depressurization

The analysis and study of the problem of the main pump of the hydraulic system pressure loss in the operation of the waste incinerator found that the cause of this fault is larger, and ultimately summarized into four factors: First, the serious wear of the main pump, resulting in the failure of the main variable mechanism, which affects the operation of the entire body of the incinerator; Second, in the process of actual operation, the safety drain valve is stuck, the operation can not be smooth. Third, the relay failure, the pressure loss of the main pump; fourth, the electromagnetic commutation rope stagnation occurs when loading. These problems, although modest, are closely related to the operation of incinerators.

III. Troubleshooting Methods for the Operation of the Incinerator

In the above summary of various common faults of the waste incinerator, it can be seen that the waste incinerator still has some problems that can not be underestimated, the following is a discussion of the faults of the waste incinerator and the measures to remove them, and the practical operations to detect, the problems found were specifically analyzed, and finally summarized in four elements that can effectively help solve the fault problem, supporting measures for construction.

1. Solving mechanical and technical problems
Analyze the debris situation in the furnace to conclude that the cause is the accumulation of debris, it is necessary to break the bridge, timely start the bridge breaking device in the hopper mouth. When the fault occurs due to excessive thickness of the debris, it is necessary to check the solid materials, timely conduct the reversible drive of the furnace grate lag, regularly check the mechanical and hydraulic systems of the grate and carry out deep maintenance, after finding the problem, it is necessary to repair or replace it in time to avoid its grate jamming.

2. Establish a reliable troubleshooting system
Timely troubleshooting is the foundation of safe machine operation, the responsibility system is the most important to build a specific system, the staff should not only identify problems in a timely manner to solve problems, the staff should also improve the troubleshooting system, prevent and reduce the occurrence of faults in advance, clearly delineate the manager's scope of responsibility, so that managers strictly control the operation of the equipment within the scope of their duties, accurately identify problems, thereby enhancing the effect of problem solving. In short, if you want to specifically deal with the occurrence of faults, establishing and improving the system is the essence of problem solving, fault repair is very useful.

3. Ways and Means to Improve Troubleshooting
When a fault occurs, there will be obvious performance, and employees will judge the fault based on accumulated experience, even if the cause of the fault is unknown, it can be accurately identified. The equipment also needs simple testing, so that it can be better applied to the construction of the supervision system, in fact, to find out the specific problems, not through specific representations to study judgment, the parameter test can help the staff strengthen the construction of the equipment operation supervision system, the parameter fluctuations can find specific problems, even better than the representation, the results obtained are more accurate, so the use of parametric standards for fault diagnosis, can improve the efficiency, improve the accuracy. In short, in the inspection equipment, the equipment also needs to apply simple tests, study the troubleshooting methods, develop a detailed repair method, can generally improve the level of modernization and standardization of major repair.

4. Improve the overall quality of the staff

The professionalism of the staff is an integral part of the overall work, has a great influence on the work of the project, only if the professionalism of each employee meets the standards, in order to be confident in the work, so in the work of a specific equipment, in order to comprehensively improve the professional skills of the staff, improve the professionalism of the staff, should not be lazy at work, ignore the details, ignore the incomprehensible problems, which will greatly increase the probability of failure. First, the staff should fully master the professional knowledge for professional knowledge, understand well, understand the steps of the work, so that they can face difficulties in practical conditions that can be solved by correct professional methods, reduce the occurrence of faults, avoid more serious accidents, ensure the basic safety of machines and personnel, second, based on professional standards for further training, the work should be detailed, can actively face each problem.

5. Using information tools
Informatization is already the mainstream method of work in modern society, Of course, garbage sorting should also be rationally classified with this simple and effective method at present, Storing data for each failure problem that occurs and solving countermeasures, enriching failure cases data and management methods, so that methods and experiences can be better summarized, provide reference resources for future problems, promote problem solving and innovation in reform methods, which is of great significance to the modern development of fault handling.

IV. Finally, the waste incinerator in the actual operation process has many problems, in the face of these problems, we also put forward various measures to solve, people's sense of responsibility is improved, the operating skills are also improved, in the continuous exploration of the waste incinerator personnel, the operation of the drainage incinerator is becoming more and more professional, and the safety and stability will also be high, effectively reducing the use of resources and environmental pollution, this will be of great significance to the future development of mankind, and also in line with our country in recent years has been calling for green environmental policy, as environmental issues are the global future crisis of mankind, so the waste incinerator must ensure the normal operation of the huge environmental crisis The standard that will achieve a win-win protection of the environment and the economy.
