Control system and method for feeding protection of feeding grate

Abstract

The invention provides a control system and method for feeding protection of a feeding grate. The control system comprises a fault detecting module and a fault handling module, wherein the fault detecting module is used for detecting faults of a sensor of the feeding grate; the fault handling module is used for controlling the feeding grate on the basis of the detected faults, so that the feeding grate stops working. By the adoption of the control system and method, production safety accidents caused by error running of the feeding grate in a rubbish incinerator can be avoided successfully, normal proceeding of production is guaranteed, and good economic benefits are generated.

Description

technical field [0001] The present disclosure relates to the incineration of garbage and other wastes, and in particular to a control system and control method for feed protection of feed grate. Background technique [0002] Waste incineration is one of the main ways to realize waste reduction, harmless and resourceful treatment. At present, garbage incineration has gradually become the main way to deal with urban domestic garbage. After modern incineration, the volume of garbage can generally be reduced by 80%-90%. At the same time, various pathogens can be eliminated, and harmful substances can be converted into harmless substances. resource utilization. [0003] Most of the existing waste incinerators use mechanical waste incinerators. figure 1 The shown garbage incinerator is just one of them. Such as figure 1 As shown, the waste incinerator includes a feed inlet 1, a feed grate 2, a fire grate 3 for waste incineration located in the furnace, a primary air supply sys...

AI Technical Summary

Problems solved by technology

However, the working environment of the feeding grate is harsh, and the rope-type displacement sensor of the feeding grate often has failures such as wire rope breakage and zero position drift due to corrosion and other reasons, resulting in the control system being unable to correctly detect the position of the feeding grate, thus The feeding grate may be stuck at the end of the mechanical stroke, making the feeding grate unable to work again, resulting in shutdown production accidents

Therefore, the staff must enter the furnace to clean up the garbage. This work generally takes 2 days, causing hundreds of thousands of major losses and increasing the labor intensity of the operators.
