[specific embodiment]
The following describes the present invention in detail with reference to the accompanying drawings and specific embodiments.
A kind of multi-pipeline differential pressure type grease platoon device, as shown in Figure 1, including gas chamber 2, gas chamber 2 is for storing
Coal gas, coal gas is supplied for each workshop, therefore, gas exit is connected to multiple coals with different pressures after being pressurized
Gas main pipeline 1, and the gas exit of each coal gas main pipeline 1 is connected to oil water separator 5.
The gaseous phase outlet of oil water separator 5 is connected to the gas entry of gas chamber 2, and is equipped with pressure on its gaseous phase outlet
Sensor 8, is also equipped with automatic regulating valve 3 on the pipeline between oil water separator 5 and gas chamber 2, pressure sensor 8 and automatic
The connection of 3 signal of regulating valve, both pressure sensor 8 and automatic regulating valve 3 establish pressure automatic linkage logic control water-oil separating
5 pressure of device, and open to enter the coal gas that the coal gas in oil water separator 5 is delivered to gas chamber when measuring pressure and reaching preset value
Mouthful.
Can be with the pressure value in real-time detection oil water separator 5 by pressure sensor 8, and reach default in measurement pressure
Automatic regulating valve 3 is sent a signal to when value, so that automatic regulating valve 3 automatically turns on and passes through the coal gas in oil water separator 5
Conveyance conduit is delivered to the gas entry of gas chamber 2.In order to guarantee that oil water separator 5 adequately separates the oil in coal gas with water
Out, it is necessary to certain differential pressure is kept between coal gas main pipeline 1 and oil water separator 5, differential pressure is 0.15~0.2MPa time-division
It is best from effect.
Liquid level sensor 9 is installed, between oil water separator 5 and grease collecting pit 6 on the liquid-phase outlet of oil water separator 5
Pipeline on be also equipped with automatic regulating valve 3, liquid level sensor 9 is used to measure the liquid level in oil water separator 5, liquid level sensor
9 are used to measure the liquid level in oil water separator 5 with automatic regulating valve 3, and open when liquid level reaches preset value by grease
Liquid in separator 5 is delivered to grease collecting pit 6.Signal connects between liquid level sensor 9 and automatic regulating valve 3, and liquid level passes
