Embodiment Construction

[0014] plan 1:

[0015] With reference to accompanying drawing 1, scheme 1 is made of pressure sensor 4, automatic controller 5, operating device 7, gas flow regulator 9. The gas 1 enters the gas flow regulator 9 through the intake pipe 2 , and enters the exhaust pipe 8 through the air guide hole 12 on the casing 10 of the gas flow regulator 9 . The liquid 6 enters the casing 10 of the gas flow regulator 9 from the pipeline 3 and flows out through the air guide hole 12 on the casing 10 or the bypass liquid-sealed pipe 11 on the casing 10 . The pressure sensor 4 collects the pressure data in the intake pipe 2 online and transmits the data to the automatic controller 5. After the automatic controller 5 processes the pressure data, it issues an action command to the action device 7, and the action device 7 drives the valve core 13 up and down. The action adjusts the position of the spool 13 in the casing 10 . As the position of the spool 13 changes, the number and area of ​​the...

Abstract

This invention relates to gas pressure automatic control device, which comprises pressure sensor, gas flow adjustor, automatic controller and operation device, wherein, pressure sensor online collects gas entrance pressure value and sends it to the controller and compares the set values and send operation order; changing gas channel section area through adjusting gas flow adjuster valve chip to control liquid adjuster gas flow to realize pressure on the gas entrance.

Description

technical field [0001] The invention is an automatic gas pressure control device, especially suitable for automatic adjustment of coke oven gas pressure. Background technique [0002] The furnace type of the conventional coking process is mainly a horizontal chamber coke oven for batch production. In the coking production process, this type of furnace must frequently open the furnace door, coal charging, coke discharge, coke quenching and other production operations at high temperature, resulting in serious pollution. Taking the 4.3m high carbonization chamber as an example, due to coal loading, the leakage of raw coal gas is not smooth, and the pressure of raw coal gas in the carbonization chamber is as high as 400Pa or more. Due to the excessive pressure, it is quite difficult to collect and divert the raw gas, smoke and fire are emitted from the furnace roof and furnace door, and a large amount of pollutants are discharged into the atmosphere, which seriously pollutes th...
