Description
Technical field
The present invention relates to the technical field of cleaner design more particularly to coal dust charging pressure release filtration systems
Background technology
Imperative as the deep processing of raw material using coal with the emergence of emerging energy, dry pulverized coal recycling gesture is essential
Technological equipment.It is most important to entire coal gas technique, it is desirable that equipment high efficiency, overpressure resistant and explosion-proof are prevented fires and stablized.
Coal dust as shown in Figure 1 is filtered through fine coal filter, and coal dust is stored in atmospheric storage tank.Atmospheric storage tank needs will be corresponding
The gas of volume is discharged in fine coal basin filter.Coal dust is packed into lock hopper by coal dust atmospheric storage tank, but since lock hopper is high pressure
Storage tank.In order to smoothly feed, pressure is discharged into fine coal basin filter before charging.Similarly coal dust is packed into fine coal from lock hopper
Feedstock vessel will also pass through this pressure releasing process.After fine coal storage tank filter filters each reservoir gas, gas is discharged into air, coal
Powder is packed into fine coal atmospheric storage tank.
Since lock hopper and fine coal feedstock vessel are high pressure storage vessel.And it is limited be subject to technique and usually requires that venting duration very
It is short.And disposable pressure release is completed.This, which results in fine coal storage tank filter, will be subject to nearly 40Mpa high pressures repeated stock.So it needs
Apparatus casing design pressure is high.It is more importantly the flexible structures such as filter bag inside equipment.And equipment inner space is limited,
It is not enough to design more effective pressure release buffer structure.And cause life of bag filter short.Maintenance is frequent.

Filter bag and cage bone service life.
This fine coal charging pressure release filter method is as follows：
Step 1, fine coal after fine coal filter under drop down onto atmospheric storage tank, at this point, the first relief valve, the second relief valve,
3rd relief valve is closed, and the 4th relief valve is opened, and is entered in atmospheric storage tank with fine coal same volume gas via the 4th pressure release branch pipe
Fine coal storage tank filter, the gas after filtering are discharged into air.
Step 2, before fine coal enters lock hopper by atmospheric storage tank, due to lock hopper be high pressure storage tank, at this time the first relief valve,
3rd relief valve, the 4th relief valve are closed, and the second relief valve is opened.Gases at high pressure by the second pressure release branch pipe via pressure release manifold,
4th pressure release branch pipe enters fine coal storage tank filter, and the gas after filtering is discharged into air, and the fine coal in atmospheric storage tank enters therewith
Lock hopper.
Step 3, before fine coal enters fine coal feedstock vessel by lock hopper, the second relief valve is closed, and the 3rd relief valve, first lets out
Pressure valve, the 4th relief valve are opened, with fine coal same volume gas via the 3rd pressure release branch pipe in fine coal feedstock vessel, pressure release manifold and the
Four pressure release branch pipes enter fine coal storage tank filter, and the gas after filtering is discharged into air.
Further, Step 1: in two, three, the gas after filtering is discharged into air, and the fine coal adsorbed on filter material is being let out
Shake off under pressure gas stream impact from surface of filter medium, fallen after rise via pipeline to atmospheric storage tank.
