Abstract
The nitrogen gas drying device for ABS powder material of the utility model has the flow that: the hermetically circular nitrogen gas drying system consists of a pressure fan, a fluidized drier, a dust filter, a nitrogen gas water scrubber and again the pressure fan reclamation. The nitrogen gas drying device has the advantages that: the utility model can prevent ABS powder material from exploding during drying process, avoid damages on equipment, factory buildings and personnel caused by explosion, and reduce economic loss. The technology is reliable.
Description
The utility model belongs to be removed liquid and carries out drying, particularly a kind of nitrogen drying device of ABS powder from solid material or goods.
In the prior art, all be to adopt airing to the ABS powder.Its process is that the ABS powder after the dehydration is sent into fluidized bed dryer, and the air after will heating with air-introduced machine is simultaneously sent into drier, and wet ABS powder is carried out fluidized drying, is used for dry air emptying after the dust filter unit dedusting.Because dry ABS dust can form explosive mixture in air, can blast running into the spark that naked light and static causes, jeopardize life safety, equipment is done great damage, device is forced to stop production.
For solving the deficiencies in the prior art, the utility model has designed a kind of with the heat carrier of nitrogen as drying, but and the drying device of the ABS powder that sealing and circulating is used in system.
ABS powder nitrogen drying Design of device scheme of the present utility model is: be communicated with the fluidized drier bottom through booster fan by inlet nitrogen A, the inlet B of ABS wet feed is arranged at the top of fluidized drier, dried ABS powder outlet C is arranged at the bottom, be used for dried nitrogen mixture from the fluidized drier top to dust filter unit, send into the nitrogen water scrubber through air-introduced machine again, constituted the nitrogen drying system of sealing and circulating again to the booster fan reuse.
This technology is that the ABS powder after the dehydration is just sent into fluidized bed dryer, and nitrogen by sending fluidized bed dryer to after the heat exchanger intensification, carries out fluidized drying to the ABS powder through boosting, and the water evaporates in the ABS powder is fallen.Owing to adopted the nitrogen of inertia to carry out drying, avoided the danger of dust explosion.Moisture, dust, nitrogen and unreacted monomer mixture fall dust-filtering by bag filter.Moisture nitrogen is extracted out by air-introduced machine, and atmosphere is advanced in part discharging, and a part is sent water scrubber to dust is washed, and nitrogen is by the cooling of washing back.Utilize the difference of water nitrogen solubility under different temperatures, water and nitrogen are separated.The nitrogen of dehydration replenishes a part of nitrogen (or replenish by blowback system) again, and the laggard drying that fluid bed continues on for the ABS powder of going into heats up through boosting.
Figure of description is the structural representation of the ABS powder nitrogen drying device of the utility model design.
The exemplary embodiments of ABS powder nitrogen drying device of the present utility model is: the nitrogen of inlet A is sent into heat exchanger (2) by booster fan (1), bottom to fluidized drier (3), deliver to nitrogen water scrubber (6) by air-introduced machine (5) after from the top of drier to dust filter unit (4) dedusting and clean, return the closed-cycle system that booster fan (1) has constituted nitrogen drying again.And the ABS wet feed is entered by drier top inlet B, after the reverse fluidisation of hot nitrogen contacts, from drier bottom discharging ABS siccative.
The danger that the ABS powder nitrogen drying device of the utility model design can avoid the ABS powder to blast in dry run, the harm to equipment, factory building and personnel of avoiding exploding reduces economic loss.This technology is reliable.
Claims (1)
1, the nitrogen drying device of ABS powder connects and composes by the pipe successively of booster fan (1), heat exchanger (2), fluidized drier (3) and dust filter unit (4) is defeated, it is characterized in that comprising air-introduced machine (5) and nitrogen water scrubber (6) from the outlet C of dust filter unit (4) to the main member of having set up the sealing and circulating drying system of nitrogen between the booster fan (1).
