Abstract
The utility model relates to a TPA feeding bin dust recovery device which comprises a feeding bin (1), wherein an emptying pipe (2) is arranged at the top end of the feeding bin (1), the TPA feeding bin dust recovery device is characterized in that an emptying valve (3) and a filter (4) are sequentially arranged on the emptying pipe (2). In the utility model, a filter is arranged behind the emptying valve so as to prevent dust from being discharged into air and reduce environmental pollution, and meanwhile, the TPA feeding bin dust recovery device has the advantages of recovering and reusing dust and achieving energy conservation and environment protection.
Description
Technical field
The utility model relates to a kind of TPA feeding bin, relates in particular to a kind of TPA feeding bin device for recovering powder, belongs to the chemical industry equipment field.
Background technology
In producing the polyester process, terephthalic acid (TPA) (TPA) is one of main material, because the TPA that throws in is Powdered; In adding the process of cast hopper, can produce static, and static runs into air and may produce spark, possibly set off an explosion or fire when serious; For fear of this type of accident, make that the air content in the TPA feeding bin reduces as much as possible, can effectively guarantee safe in utilization; Therefore be provided with evacuated tube at the top of feeding bin, in time get rid of air in the storehouse, evacuated tube is taken a certain amount of TPA dust easily out of in discharged air in feeding bin; Cause waste to a certain extent, and polluted environment.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, provides a kind of and can reclaim dust and reduce the TPA feeding bin device for recovering powder that pollutes.
The purpose of the utility model is achieved in that a kind of TPA feeding bin device for recovering powder, comprises feeding bin, and the top of said feeding bin is provided with blow-down pipe, is provided with atmospheric valve and filter on the said blow-down pipe successively.
Compared with prior art, the beneficial effect of the utility model is:
The utility model is provided with filter at the rear of atmospheric valve, can prevent dust emission in air, reduces environmental pollution, also can recycle and reuse dust simultaneously, reaches the advantage of energy-conserving and environment-protective.
