Abstract

The utility model discloses equipment for recovering and utilizing exhaust gas during the deep processing of coal tar, which is composed of an exhaust gas discharge pipe (1) used in the deep processing of coal tar and is characterized in that the exhaust gas discharge pipe (1) is led into an oil wash absorption tower (3) by an exhaust gas collecting pipe (2) so as to recover organic matters through oil wash in the oil wash absorption tower (3); after being processed by the operation of oil wash, exhaust gas which flows out from an outlet (6) flows into a water scrubbing tower (8) through a pipeline (7) so as to be processed by the operation of water scrubbing in the water scrubbing tower (8); after water scrubbing, the exhaust gas is led into a combustor (13) so as to be combusted and utilized again; and an oil-water mixture is led into an oil water separator (15) after water scrubbing. The equipment for recovering and utilizing exhaust gas during the deep processing of coal tar has the advantages that exhaust gas generated during production is processed by the operations of oil wash and water scrubbing, and the organic maters in the exhaust gas and the remainder of exhaust gas can be recovered and utilized, therefore, the equipment eliminates environmental pollution caused by the exhaust gas, saves energy, reduces the production cost of the deep processing of coal tar and can be widely applied to enterprises for deeply processing the coal tar.

Description

Waste gas recycling equipment during coal tar deep processing is produced

Technical field

The utility model relates to a kind of waste gas reclaimer, the waste gas recycling equipment during particularly a kind of coal tar deep processing is produced.

Technical background

At present, in coal tar deep processing is produced, employed raw material tank, medial launder, unload recessing, wastewater trough, glance coal trap, all have the waste gas exhaust stack, the waste gas that is produced freely distributes to atmosphere from the waste gas exhaust stack, its weak point is: the one, some useful organic substances (as naphthalene, phenol, light oil etc.) are directly diffused into atmosphere, caused the wasting of resources, simultaneously, some combustible exhaust gas have not directly been utilized, also cause energy waste, therefore also improved production cost; The 2nd, some pernicious gases are directly put into atmosphere, can cause environmental pollution.

Summary of the invention

The purpose of this utility model is to provide a kind of above deficiency of the prior art that overcomes, the waste gas that is produced in the coal tar deep processing production is carried out comprehensive reutilization, thereby avoid environmental pollution, and can energy efficient, the coal tar deep processing that the reduces production costs waste gas recycling equipment in producing.

For reaching above purpose, the technical scheme that the utility model adopted is: the waste gas recycling equipment during this coal tar deep processing is produced, constitute by the waste gas exhaust stack in the coal tar deep processing, it is characterized in that the waste gas exhaust stack is connected with the waste gas manifold trunk, the waste gas manifold trunk is connected with the exhaust gas entrance that compiles on oil wash absorption tower, the all waste gases that is produced in the coal tar deep processing is input in the oil wash absorption tower, on the sidewall of the bottom on oil wash absorption tower, establish the outlet of oil wash organic matter, waste gas outlet after oil wash is established on the top on oil wash absorption tower, it is the remainder of exhaust gas outlet after organic substance absorbs, compiling waste gas absorbs with the washing oil washing in the oil wash absorption tower, to compile the organic substance (naphthalene in the waste gas, phenol, light oil etc.) dissolving absorbs, utilize by reclaiming again, behind the oil wash waste gas outlet by the bottom oil wash of pipeline and water scrubber after exhaust gas inlet be connected, waste gas is transported in the water scrubber after making oil wash, further detergent is used in water scrubber, establish washing back waste gas outlet on the top of water scrubber, establish the oil-water mixture outlet of washing back in the bottom of water scrubber, washing back waste gas outlet connects burner by communicating pipe through air-introduced machine, the utilization of burning that acts as a fuel in burner of waste gas after the washing, the oil-water mixture outlet of washing back is connected with oil water separator by corresponding pipeline.The utility model is also implemented by following measure: be exported at oil-water mixture after the washing and establish washing back oil-water mixture delivery pump on the corresponding pipeline of oil water separator, by wash back oil-water mixture delivery pump with the washing in the water scrubber after oil-water mixture send into oil water separator, like this, through oil wash and washing two procedures, can all combine and utilize the waste gas that produces in the coal tar deep processing; Waste gas exhaust stack in the described coal tar deep processing, comprise raw material tank waste gas exhaust stack, medial launder waste gas exhaust stack, unload recessing waste gas exhaust stack, wastewater trough waste gas exhaust stack, glance coal trap waste gas exhaust stack, all be connected with same waste gas manifold trunk; The structure of described oil wash absorption tower and water scrubber is prior art, so seldom state; Oil wash organic matter in bottom, oil wash absorption tower is exported on the pipeline that mixes oil groove establishes oil wash organic matter miscella delivery pump, the oil wash organic substance miscella that reclaims is transported to mixes in the oil groove; On oil-water mixture delivery pump after the washing and the corresponding pipeline of oil wash organic matter miscella delivery pump, also be provided with switch; Described burner can be boiler or tube furnace; Oil-water mixture also can be continued to be input in the water scrubber washing once more after the washing of flowing out from water scrubber by washing back oil-water mixture delivery pump.

The beneficial effects of the utility model are: because the waste gas during coal tar deep processing produced is by oil wash and washing, make organic matter wherein obtain recycling, remainder of exhaust gas has also obtained recycling, so, not only eliminated the pollution of waste gas to environment, and the saving energy, reduced the coal tar deep processing production cost, can be widely used in coal tar deep processing enterprise.
