Abstract
The invention provides a waste gas filtering and purifying device which comprises a waste gas pipeline and a purification tower connected in sequence. The purification tower comprises a padding demister, a filter material reactive layer and a feed liquid spraying device sequentially from upside to downside; the top part of the purification tower is connected with a purification pipeline; a water inlet pipeline is externally connected to the spraying device while the other end of the water inlet pipeline is communicated with a water pond; the bottom of the purification tower is communicated with the water pond; the entrance of the waste gas pipeline is located on a cooling channel. With the adoption of the waste gas filtering and purifying device, waste gas in the cooling channel can be purified and filtered efficiently, harmful gas and insoluble substances such as tar in the waste gas can be removed, purified water in the whole set of device can be recycled, resource and cost can be saved, and the waste gas filtering and purifying device is small in floor area and easy to operate and maintain.
Description
Technical field
The invention belongs to industrial waste gas process field.
Background technology
In sandbox casting on casting automatic production line, casting mold after usual cast can produce containing flue dust, tar, carbon monoxide and carbon dioxide etc., the waste gas of toxic gas, these materials can cause fan trouble after entering cooling pipe with casting mold and there is the hidden danger such as environmental pollution.At present, waste gas processing method comprises in line, charcoal absorption, pipeline spray lime or dust-removing powder and absorbs sedimentation, but all there is secondary pollution or treatment cost is high.
Summary of the invention
The object of this invention is to provide and a kind ofly avoid secondary pollution, waste gas filtering purifier with low cost.
The present invention is achieved by the following technical programs: a kind of waste gas filtering purifier, comprise the exhaust piping be connected successively, purifying column, described purifying column comprises filler demister from top to bottom successively, filtrate conversion zone, feed flow spray equipment, described purifying column top connects purification pipeline, the external inlet channel of described spray equipment, and the described inlet channel other end is communicated with pond, be communicated with described pond bottom described purifying column, described exhaust steam passage entrance is positioned on cooling duct.
The external blower fan of described purification pipeline, described blower fan is communicated with exhaust chimney.
In the middle of described pond, upper end is provided with flashboard, lays respectively at described flashboard both sides bottom described inlet channel and described pond connector, described purifying column with described pond connector.
Top, described pond is provided with overfall, and lower end is provided with blowdown drain.
Described basin bottom is inclined design, and described blowdown drain is positioned at inclined-plane low side at the bottom of pond.
Described pond is provided with dosing tank near described inlet channel place, and described pond is communicated with by water pump with described water inlet pipe.
The present invention has following beneficial effect:
Effective purifying exhaust air, avoids environmental pollution; Avoid the materials such as tar in waste gas on the impact of casting transfer matic subsequent handling; Water can recycle, and economizes on resources; Compact equipment, floor space is little.
Accompanying drawing explanation
Below in conjunction with specific embodiment, the present invention will be further described.
Fig. 1 is the structural representation that the invention provides a kind of sea water desalinating unit.
In figure: 1. cooling duct, 2. exhaust piping, 3. purifying column, 4. purify pipeline, 5. inlet channel, 6. water pump, 7, dosing tank, 8. pond, 9. blowdown drain, 10. flashboard, 11. overfalls, 12. exhaust chimney, 13. blower fans.
Detailed description of the invention
Below in conjunction with accompanying drawing, by embodiment, the present invention is described further.
Embodiment: as shown in the figure, waste gas filtering purifier handling process of the present invention is as follows: after the waste gas in cooling duct 1 sucks purifying column by blower fan 13, with by the dosing of dosing tank 7 water feeder 8, to ensure in pond 8 that concentration of sodium hydroxide solution is with in constant range, water pump 6 by pond 8 Chinese medicine by feed flow spray equipment in Cemented filling to purifying column 3, feed flow spray equipment carries out spray operation to entering waste gas in purifying column 3, make medicament and waste gas hybrid reaction, gas-liquid mixed material rises and enters filtrate conversion zone, medicament and waste gas are fully reacted and filters the impurity produced, residue aerosol, through filler demister, carry out the demist operation that dewaters, purified gas is through purification pipeline 4, discharged by exhaust chimney by blower fan 13, after the operation of spray equipment spray, unnecessary medicament can reenter pond 8 by purifying column 3 outlet at bottom and recycles.
Carry out in purification process at waste gas, the insoluble matters such as flue dust precipitation and not processed tar completely can be produced, under gravity, enter pond 8 by the outlet bottom purifying column, sediment is sunk to bottom pond 8 and is discharged by blowdown drain, and the insoluble matters such as tar swim in top layer, pond 8, discharged by overfall 11 after reaching a certain height, focus on after can collecting.
waste gas filtering purifier described in the embodiment of the present invention, can pernicious gas and tar etc. effectively in filtering exhaust not tolerant; Purify waste water and can recycle, economize on resources and cost; Occupation area of equipment is little, is easy to Operation and Maintenance; Treatment process is simple.
above content is the further description done the present invention in conjunction with concrete embodiment, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, some simple deduction or replace can also be made, all should be considered as belonging to protection scope of the present invention.
