Embodiment Construction

[0022] The basic technological process of waste incineration is as follows: municipal solid waste is collected by the environmental sanitation department and transported to the waste incineration power station, stored in the waste storage pool, then grabbed by the waste crane 1, enters the well 3 from the hopper 2, and fills the hopper 2 with the material. The well 3 closes the furnace chamber 4 . Use hydraulic feeder 5 according to combustion control instruction and rubbish is added in the stove by the speed of setting. The rubbish burns on the fire grate 6 moving in the furnace. During the incineration process, the primary air 7 is blown in from the air chamber 7 below the fire grate, passes through the garbage layer, and reacts with the garbage at the same time to promote the burning of the garbage. The secondary air is blown in by the air pipe 8 above the fire grate, and the main effect of the secondary air is to impel volatile gas and unburned rubbish on the material bed...

Abstract

A method for controlling the incineration procedure of garbage incinerator includes such steps as measuring the real-time parameters of incinerator, creating the primary fuzzy controller, correcting the output of primary fuzzy controller, regulating the opening of the air gate of blower, regulating the fire power, and regulating the opening of air gate of exhauster. Its advantage is full combustion of garbage.

Description

technical field [0001] The invention belongs to the field of combustion process control, and relates to a control method for the combustion process of a garbage incinerator, in particular to an intelligent control method for the combustion process of a grate type garbage incinerator. Background technique [0002] At present, the combustion process of waste incinerators is basically controlled by the traditional proportional-integral-derivative (PID) method. PID control uses the furnace temperature deviation as the control input, and adjusts according to the basic principle that the addition of materials will cause the temperature to rise. Because the furnace temperature is constantly fluctuating, the furnace temperature deviation of the control input is constantly changing, and the corresponding control output is also constantly changing, while the control output of PID adjustment is the speed of feeding rather than whether feeding, which is a continuous feeding control metho...
