Abstract
The invention discloses a tail gas treatment device, which comprises a gas and sand separator, wherein the gas and sand separator has a triethylamine tail gas inlet; the outlet of the gas and sand separator is connected with a purifying tower through a fan; and the purifying tower is connected with a water pump and an acid pump. When the tail gas treatment device is used, the triethylamine tail gas enters the gas and sand separator from the triethylamine tail gas inlet, so that the triethylamine tail gas inlet and molding sand can be separated; then the triethylamine gas is driven by a fan to enter the purifying tower, and water and phosphoric acid are conveyed into the purifying tower by the water pump and the acid pump to neutralize triethylamine; and finally, the neutralized liquid is discharged from the purifying tower. The tail gas treatment device can effectively neutralize triethylamine, the triethylamine content after treatment is below 25PPM and reaches a national discharge standard, and thus, the pollution caused by triethylamine to the environment is avoided.
Description
Technical field
The present invention relates to the casting and molding technical field, particularly a kind of exhaust gas processing device of handling the triethylamine of core hardening process use.
Background technology
At present in foundry production, in order to improve the efficient of casting, cold-box core blower manufacturing is adopted in the moulding of core more, after the core manufacturing is finished, in order to prevent the core distortion, usually need harden to core, at present be to use triethylamine to make the core sclerosis to the core method commonly used of hardening, generally be to feed triethylamine to make the core sclerosis on core.But in this process, often having a large amount of triethylamine tail gas reveals, triethylamine is a kind of toxic gas of alkalescence, can pollute environment on every side if directly be discharged in the air, therefore triethylamine need be put together and handle, wait to reach after the discharging national standard and to discharge in could be outwards, and still do not have a kind of so special treating apparatus to handle at present triethylamine.
Summary of the invention
At above-mentioned the deficiencies in the prior art, the technical problem to be solved in the present invention provides a kind of exhaust gas processing device that is used for handling triethylamine waste gas specially.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of exhaust gas processing device, it comprises a gas sand separator, and described gas sand separator is provided with the triethylamine gas inlet, and the gas outlet of described gas sand separator is connected with a purifying column by a blower fan, and described purifying column is a water pump and a sour pump connection also.
Preferably, described blower fan is sealed in the acoustic hood.
Preferably, the bottom of described purifying column is provided with a blowoff valve.
Technique scheme has following beneficial effect: this exhaust gas processing device is waited in use, triethylamine tail gas enters in the gas sand separator by the triethylamine gas inlet, triethylamine gas is separated with molding sand, triethylamine gas is driven by blower fan and is passed in the purifying column then, by water pump with sour pump imports water in purifying column and phosphoric acid is neutralized triethylamine, the liquid after will neutralizing is again at last discharged in purifying column.This exhaust gas processing device can effectively neutralize to triethylamine, and the triethylamine content after the processing reaches discharging standards below 25PPM, can avoid triethylamine that environment is polluted.
Above-mentioned explanation only is the general introduction of technical solution of the present invention, for can clearer understanding technological means of the present invention, and can be implemented according to the content of specification, below with preferred embodiment of the present invention and conjunction with figs. describe in detail as after.The specific embodiment of the present invention is provided in detail by following examples and accompanying drawing thereof.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
The specific embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described in detail.
As shown in Figure 1, this exhaust gas processing device comprises a gas sand separator 2, gas sand separator 2 is provided with triethylamine gas inlet 1, the gas outlet of gas sand separator 2 is connected with a purifying column 8 by a blower fan 3, purifying column 8 is a water pump 7 and sour pump 5 connections also, also are provided with a blowoff valve 6 in the bottom of purifying column 8.Noise when working in order to reduce blower fan 3, blower fan 3 is sealed in the acoustic hood 4.
This exhaust gas processing device is waited in use, triethylamine tail gas enters in the gas sand separator 2 by triethylamine gas inlet 1, triethylamine gas is separated with molding sand, triethylamine gas is driven by blower fan 3 and is passed in the purifying column 8 then, by water pump 7 with sour pump 5 imports water in purifying column 8 and phosphoric acid is neutralized triethylamine, the liquid after will neutralize more at last is by blowoff valve 6 discharges in the purifying column 8.
Can effectively neutralize to triethylamine by this exhaust gas processing device, the triethylamine content after the processing reaches discharging standards below 25PPM, can avoid triethylamine that environment is polluted.
More than a kind of exhaust gas processing device that the embodiment of the invention provided is described in detail; for one of ordinary skill in the art; thought according to the embodiment of the invention; part in specific embodiments and applications all can change; in sum; this description should not be construed as limitation of the present invention, and all any changes of making according to design philosophy of the present invention are all within protection scope of the present invention.
