Energy-saving control method and device of dust removal blower of coke oven

Abstract

The invention relates to an energy-saving control method and device of a dust removal blower of a coke oven, which is characterized in that a dust removal conducting pipeline of a coke oven vehicle is internally provided with a pressure signal collecting device for continuously collecting pressure numerical values in the conducting pipeline during dust removal; the collected pressure numerical values are outputted into a dust removal PLC (Programmable Logic Controller) system of the coke oven; the dust removal PLC system of the coke oven is used for carrying out comparative operation on the received pressure numerical values and a set numerical value and transmitting a control signal to a speed regulating device of the blower; the speed regulating device of the blower is used for regulating the rotating speed of the blower according to the control signal; and the dust removal PLC system of the coke oven is used for outputting the control signal for controlling the dust removal blower to run at the current rotating speed until the measured pressure value in the dust removal conducting pipeline on the coke oven vehicle is equal to the set numerical value. The invention has the advantages that for coking chambers in different positions of the coke oven, the rotating speed of the blower in high-speed running can be respectively regulated and controlled; and thereby, when the dust of any coking chamber of the coke oven is removed, the actual wind quantity for the dust removal is equal to the wind quantity required by the dust removal so as to achieve the purpose of controlling the blower to run under an energy-saving condition.

Description

technical field [0001] The invention relates to the technical field of energy saving, in particular to an energy-saving control method and device for the operation of a fan of a coke oven dust removal system. Background technique [0002] The current coke oven dedusting fan control technology is based on the intermittent characteristics of coal charging and coke discharge operations in coke oven production, and simply sets two operating states of high speed and low speed. When there is no coal loading or coke discharge operation, the coke oven dust removal PLC control system controls the fan to run at low speed; when the coke oven is in coal charging or coke discharge operation, the coke oven dust removal PLC control system controls the fan speed to increase and run at full speed . [0003] The current coke oven configuration and operation are as follows: a coke oven is usually composed of 40 to 75 carbonization chambers, generally two coke ovens form a furnace group, and a...

Problems solved by technology

Since the fan of the dust removal system is selected according to the designed dust removal air volume of the carbonization room farthest from the fan, the current control technology of the coke oven dust removal fan makes the actual dust removal air volume of other carbonization rooms larger than the air volume required for dust removal. caused a waste of energy
