The utility model discloses exhaust gas treating device, tail gas pass through water uptake acidic material and hydrophilic organic solvent, through circulation system's spray rinsing, realize abundant absorption, and be gaseous in the molecular sieve can release the air, reduces environment ground destruction many times.

Description

A kind of exhaust gas processing device
Technical field
This utility model belongs to technical field of chemical, especially a kind of exhaust gas processing device.
Background technology
In chemical and petrochemical industry, the process problem of generation waste gas being always up to the problem of research, most of factories use the means of burning or washing tail gas to realize, for H2S、SO2、NH3, the similar substance such as phthalic anhydride, adopt is built device for absorbing tail gas and is washed more.Existing production technology, fixed gas is mainly used as the tail gas of process units be directly discharged to torch and carry out burn processing, produces source it can be seen that the key component of this tail gas is exactly raw material from tail gas, this processing method material loss is bigger, cost of material increases, and causes the waste of resource, or in process of production, due to without total condensation, portion of product is carried out with tail gas, causes the reduction of productivity, have a strong impact on benefit.
Utility model content
For the problems referred to above, the purpose of this utility model is in that especially a kind of exhaust gas processing device of offer, and this apparatus structure is reasonable in design, it is possible to the effective mineral acid removed in tail gas, and can carry out raw material and product reclaiming purification, is conducive to protection environment.
This utility model solves above-mentioned technical problem and be the technical scheme is that
A kind of exhaust gas processing device, it is characterized in that, including surge tank, condenser, absorption tower and vacuum distillation tower, described condenser is arranged at the top of surge tank, described condenser and absorption tower are arranged in series, described absorption tower is provided with shower water entrance, communicate between described spray head entrance and spray head, described spray head is connected with circulating pump by pipeline, described absorption tower leacheate tail gas absorption after outlet is arranged below, the outlet of described leacheate is arranged by pressure-reducing cushioning series connection of pumps with vacuum distillation tower, described vacuum distillation tower be arranged above with decompressor, described vacuum distillation tower arranges multiple flaggy, described flaggy is provided with corresponding catcher, described catcher can according to the difference of boiling point, collect different fractions.
Further, described vacuum distillation tower arranges 4~6.
Further, described catcher is corresponding with corresponding flaggy.
Further, the top on described absorption tower is equipped with molecular sieve filter.
The utility model has the advantage of:
This utility model exhaust gas processing device, tail gas absorbs acidic materials and hydrophilic organic solvent by water, hydro-peening through blood circulation repeatedly, realizing absorbing fully, gas can be discharged in air through molecular sieve, reduces the destruction to environment, and the eluent outlet absorbed, enter decompression distillation, according to the difference of boiling point, component is easily separated, collect part material or product.
