Description
Technical field
The utility model is related to the technical field of cleaner design, more particularly to coal dust charging pressure release filtration system
Background technology
With the emergence of emerging energy, the deep processing using coal as raw material is imperative, and dry pulverized coal recovery is bound to indispensable
Technological equipment.It is most important to whole coal gas technique, it is desirable to equipment high efficiency, overpressure resistant and explosion-proof, fire prevention and stably.
Coal dust as shown in Figure 1 is filtered through fine coal filter, and coal dust is stored in into atmospheric storage tank.Atmospheric storage tank needs will be corresponding
The gas of volume is discharged in fine coal basin filter.Coal dust loads lock hopper by coal dust atmospheric storage tank, but because 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 loads 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 loads fine coal atmospheric storage tank.
Because lock hopper and fine coal feedstock vessel are high pressure storage vessel.And limited by technique and usually require that venting duration very
It is short.And disposable pressure release is completed.This results in fine coal storage tank filter will be by nearly 40Mpa high pressures repeated stock.So needing
Apparatus casing design pressure is high.More importantly device interior is the flexible structures such as filter bag.And device interior 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.
Utility model content
The purpose of this utility model, by the discouraged air flow duct of optimization, plays the purpose of protection fine coal storage tank filter.

Pressure relief opening and fine coal feedstock vessel pressure relief opening are connected by pipeline with atmospheric storage tank respectively, and atmospheric storage tank pressure relief opening passes through pipeline and powder
Coal storage tank filter is connected.In the case where original base structure is constant, by adjusting the arrangement of pressure release airflow line, by tank body
Interior air-flow imports atmospheric storage tank and depressurized, it is to avoid gas flow rate is too high, the filter material directly impacted in fine coal storage tank filter, leads
Filter material is caused to damage.
Further, lock hopper pressure relief opening is connected by the second pressure release branch pipe with pressure release house steward；Fine coal feedstock vessel pressure relief opening leads to
The 3rd pressure release branch pipe is crossed to connect with pressure release house steward；Pressure release house steward directly connects with atmospheric storage tank, and atmospheric storage tank pressure relief opening passes through
Four pressure release branch pipes are connected with fine coal storage tank filter.The pressure release house steward is provided with the first relief valve close to atmospheric storage tank end；It is described
Second pressure release branch pipe is provided with the second relief valve close to lock hopper end；The 3rd pressure release branch pipe is provided with the 3rd close to fine coal feedstock vessel end
Relief valve；The 4th pressure release branch pipe is provided with the 4th relief valve close to atmospheric storage tank end.Except by lock hopper and fine coal feedstock vessel
Gas inputs atmospheric storage tank by independent pipeline, can also further carry out pipeline optimization, by losing heart for lock hopper and fine coal feedstock vessel
Pipeline accesses single pressure release house steward, accesses atmospheric storage tank by sharing a pressure release house steward, further reduces conveying pressure release
The setting of pipeline, reduces the space-consuming of equipment, the capital improvement cost of reduction.
The caliber of the 4th pressure release branch pipe is more than the caliber of other relief pipelines.Release of pressure and increase by atmospheric storage tank
The caliber of end, can be by flow control in the range of the permissible velocity of 18 meter per seconds.Fine coal basin filter interior can be ensured
Filter bag and cage bone life-span.
This fine coal charging pressure release filter method is as follows：
Step one, atmospheric storage tank is dropped down onto under fine coal is after fine coal filter, now, 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 is discharged into air.
Step 2, fine coal by atmospheric storage tank enter lock hopper before, due to lock hopper be high pressure storage tank, now 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 house steward,
4th pressure release branch pipe enters fine coal storage tank filter, and the fine coal that the gas after filtering is discharged into air, atmospheric storage tank enters therewith
Lock hopper.
Step 3, in fine coal before lock hopper enters fine coal feedstock vessel, the second relief valve is closed, the 3rd relief valve, and first lets out
Pressure valve, the 4th relief valve is opened, with fine coal same volume gas via the 3rd pressure release branch pipe in fine coal feedstock vessel, pressure release house steward and
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, 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.
