Description
Technical field
The present invention relates to a kind of exhaust gas processing device, particularly relate to a kind of exhaust gas processing device being applied to MAQ-ME, mainly belong to the technical field of chemical industry equipment.
Background technology
R-(+)-2-(4-hydroxyphenoxy) methyl propionate, the manufacture of chemistry by name MAQ-ME, MAQ-ME is through synthetic reaction, washing, layering, crystallization, the operation such as centrifugal complete.Containing certain moisture and solvent toluene after product is centrifugal, product quality requires that moisture is less than 0.3%, and toluene level is less than 0.5%, so require that product has to pass through drying process and just can meet quality standard.Original drying equipment is pellet type atmospheric box type drying oven, drying time is long, although the product moisture of drying, the content of toluene can reach requirement, but solvent toluene evaporate in air and causes atmosphere pollution, and product loss is large, the dehumidified blower fan of partial material is blown in air, also causes atmosphere pollution; Due to expose in atmosphere and drying time long, product is easily oxidized, causes the yellowish appearance of product.
This has been made to improvement in prior art, adopt bipyramid rotary drier to carry out drying, tail gas detaches discharge by vacuum pipe, but except steam, still contains part toluene in tail gas, can pollute air.
Summary of the invention
The object of the invention is to propose a kind of exhaust gas processing device for MAQ-ME drying.
Above-mentioned purpose of the present invention will be achieved by the following technical programs: for the exhaust gas processing device of MAQ-ME drying, be installed in the offgas outlet of the bipyramid rotary drier of MAQ-ME drying, it is characterized in that: described exhaust gas processing device comprises oilless vacuum pump, deep condenser, solvent recipient and exhaust emissions condenser, described oilless vacuum pump one end connects the offgas outlet of bipyramid rotary drier and the other end is provided with the vavuum pump conduit being connected to solvent recipient top, described deep condenser is located on vavuum pump conduit, the another side, top of described solvent recipient is provided with exhaust emissions passage, described exhaust emissions condenser is installed in exhaust emissions passage.
Further, between the described buffer offgas outlet that is arranged in bipyramid rotary drier and oilless vacuum pump.
Apply exhaust gas processing device of the present invention, can prevent air from entering the drier of MAQ-ME, effective suppression product is oxidized, improve product quality, reduce product consumption, the moisture simultaneously evaporated by product and toluene detach and process, and improve the purity level of product on the one hand, reclaim toluene on the other hand, reduced containing the pollution of toluene tail gas to air.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention for the exhaust gas processing device of MAQ-ME drying.
Detailed description of the invention
Below just accompanying drawing in conjunction with the embodiments, is described in further detail the specific embodiment of the present invention, is easier to understand, grasp to make technical solution of the present invention.
As shown in Figure 1, for the exhaust gas processing device of MAQ-ME drying, be installed in the offgas outlet of the bipyramid rotary drier 1 of MAQ-ME drying.From technical characteristic, this exhaust gas processing device comprises oilless vacuum pump 2, deep condenser 3, solvent recipient 4 and exhaust emissions condenser 5.Wherein this oilless vacuum pump 2 one end connects the offgas outlet of bipyramid rotary drier 1 and the other end is provided with the vavuum pump conduit 6 being connected to solvent recipient top, and deep condenser 3 is just located on this vavuum pump conduit 6, the another side, top of this solvent recipient 4 is provided with exhaust emissions passage 7, and exhaust emissions condenser 5 is then installed in exhaust emissions passage 7.Realize thus detaching the vacuum of tail gas, multiple condensation cleaning.
In addition, for optimizing this device, exhaust gas processing device is also provided with buffer 8, and buffer 8 one end connects the offgas outlet of bipyramid rotary drier 1, and the other end connects oilless vacuum pump 2.
During concrete enforcement, open oilless vacuum pump, the tail gas that bipyramid rotary drier produces passes through buffer buffers, partial tail gas reclaims, and then residual exhaust carries out first step condensation by vavuum pump conduit penetration depth condenser, and condensed liquid enters solvent recipient, tail gas remaining after first step condensation carries out second step condensation through exhaust emissions condenser again, condensed liquid flows back to solvent recipient, and the tail gas that final condensation terminates not containing formaldehyde, can be discharged along exhaust gas channel substantially.
Can be found out by above-mentioned character express, beneficial effect of the present invention: apply exhaust gas processing device of the present invention, can prevent air from entering the drier of MAQ-ME, effective suppression product is oxidized, improves product quality, reduces product consumption, the moisture simultaneously evaporated by product and toluene detach and process, improve the purity level of product on the one hand, reclaimed toluene on the other hand, reduced containing the pollution of toluene tail gas to air.
In addition to the implementation, the present invention can also have other embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the present invention's scope required for protection.
