Abstract

The utility model relates to a waste gas treatment system during PTA activated sludge uses multipurposely, including cyclone and the quench tower that connects gradually with cyclone, sack cleaner and chimney, be equipped with the air exhauster between quench tower and sack cleaner, be equipped with the draught fan between sack cleaner and chimney, cyclone still connects screw conveyer, and cyclone one side lower part is equipped with the air intake. Waste gas after waste gas treatment system handles reaches the emission requirement of " dangerous waste incineration pollution control standard ", can directly discharge, when realizing resource recycling, avoids environmental pollution, is favorable to sustainable development.

Description

Exhaust treatment system in the comprehensive utilization of PTA activated sludge
Technical field
The utility model relates to a kind of exhaust treatment system, especially relates to the exhaust treatment system in the comprehensive utilization of a kind of PTA activated sludge.
Background technology
Along with the development of China's polyester chemical fibre industry, the production capacity of basic material PTA constantly expands.Up to the present domestic newly-increased PTA production capacity 4,400,000 t/a, aggregated capacity reaches 1,996 ten thousand t/a.Will produce a large amount of containing cobalt, manganese waste material, high concentration PTA waste water in PTA production process, containing PTA, terephthalic acid (TPA) and cobalt acetate manganese in waste water, cobalt acetate manganese also containing 1.2%-1.5% in waste residue, activated sludge, a large amount of precious resources cannot be recycled recycling, traditional activated sludge landfill both wasted land resource, serious environment pollution simultaneously, so the comprehensive utilization of PTA activated sludge is extremely urgent, but can a large amount of waste gas be produced in the comprehensive utilization of PTA activated sludge, if directly discharge can serious environment pollution.
Summary of the invention
The utility model is intended to solve the problem, and provides the exhaust treatment system in the comprehensive utilization of a kind of PTA activated sludge, reduces environmental pollution.
In order to overcome the defect existed in background technology, the utility model solves the technical scheme that its technical problem adopts: the exhaust treatment system in a kind of PTA activated sludge comprehensive utilization, the quench tower, sack cleaner and the chimney that comprise cyclone dust collectors and be connected successively with cyclone dust collectors, air exhauster is provided with between described quench tower and sack cleaner, air-introduced machine is provided with between sack cleaner and chimney, described cyclone dust collectors also connect conveying worm, and cyclone dust collectors one side lower part is provided with air inlet.
In a preferred embodiment of the present utility model, cyclone dust collectors are the casing of cylindrical shape steel construction
The beneficial effects of the utility model are: the emission request that the waste gas after exhaust treatment system process reaches " dangerous waste incineration Environmental capacity standard ", can directly discharge, while realizing resource recycling, avoid environmental pollution, be conducive to sustainable development.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Exhaust treatment system as shown in Figure 1 in a kind of PTA activated sludge comprehensive utilization, the quench tower, sack cleaner and the chimney that comprise cyclone dust collectors and be connected successively with cyclone dust collectors, air exhauster is provided with between quench tower and sack cleaner, air-introduced machine is provided with between sack cleaner and chimney, cyclone dust collectors also connect conveying worm, and cyclone dust collectors one side lower part is provided with air inlet; Cyclone dust collectors are the casing of cylindrical shape steel construction.
Cyclone dust collectors are the cleaners removing bulky grain dirt.Air enters the casing of cylindrical shape steel construction from the side, rises to pipeline after gas rotating, and coarse granule flue dust declines and precipitates, and sends to conveying worm.Cyclone dust collectors and quench tower mainly remove coarse granule dirt and cooling further, in case cross heat smoke to burn out cloth bag, the waste gas of going out from cyclone dust collectors is extracted into sack cleaner by air exhauster.
Sack cleaner is a kind of highly effective dry-type deduster, and be the filter bag relying on fiber filtering to make, more importantly carry out Purge gas by the dust layer that filter bag is formed on the surface, its efficiency of dust collection reaches more than 99.8%.Its efficiency of dust collection of sack cleaner is high, particularly has higher efficiency to fine dust, generally can reach more than 99.5%, and this project dust emission concentration and rate of discharge are respectively 25mg/m3,0.5kg/h, is less than the 100mg/m3 that discharge standard requires.
To produce according to " explanation about p-phthalic acid's production technology and waste water processes ": PTA and in sewage disposal process, owing to not using or adding industrial chemicals, auxiliary material or the auxiliary agent containing chlorion.Therefore the mud produced in PTA sewage disposal process not containing chlorion composition, also would not produce the pollutants such as dioxin, cause secondary pollution to environment in PTA sludge incineration process.
In sum, this project adopts the flue gas treating process of " cyclone dust removal (rotary kiln flue gas)+quench tower+sack cleaner ", dust clearance can reach more than 99.5%, after process, dust emission concentration is 25mg/m3, SO2 concentration of emission 8mg/m3, NOx emission concentration 37.4mg/m3, flue gas, by 25m chimney high altitude discharge, can reach the requirement discharge standard requirement of " dangerous waste incineration Environmental capacity standard ".
