Abstract
The technological process for neutralizing coking waste water and flue water gas is characterized by that the coking waste water and flue waste gas are simultaneously fed into the dust-removing desulfurizing equipment to implement neutralization reaction, after the flue gas is undergone the processes of removing dust and desulfurization and reached to standard, it can be discharged, and the ash water is undergone the processes of precipitation and separation through the separation, then flower into coke powder adsorption filtration pool to make adsorption and filtration, and after it reaches to the standard, it can be recovered and reused, and its filter material also can be used as raw material for reuse.
Description
The present invention relates in a kind of coking chemical waste water and the stack gases and administer technology, be applicable to the comprehensive regulation of large-lot producer's coal washing gas sewage such as coking, coal gas, iron and steel, chemical industry and stack gases.
At present, some large-lot producer of China handle respectively factory effluent and waste gas, and are time-consuming, involve great expense, and what have does not deal with direct discharging with waste gas, increase pollutant discharge of enterprise and take, and not only business economic is impaired, and contaminate environment.
The objective of the invention is to have proposed in a kind of coking chemical waste water and the stack gases and improvement technology to the problem that produces waste water and waste gas pollution control and treatment aspect in producing and exist at some large-lot producer of present China, this technology is to carry out neutralization reaction with containing the waste water of alkalescence and containing tart waste gas, the discharging after the purification of dedusting neutralization reaction is up to standard with sulfur dioxide in flue gas and dust, water after the processing and filtrate reuse, reached the purpose of the treatment of wastes with processes of wastes against one another, not only save the expense expenditure of enterprise greatly, also reduced environmental pollution.
Purpose of the present invention is realized by following measures:
Improvement processing step of the present invention be with coking chemical waste water behind the equalizing tank homogeneous, squeeze in the dust-removing desulfurating apparatus through the water-in on dust-removing desulfurating apparatus top with sump pump, stack gases enters in the dust-removing desulfurating apparatus from the gas approach of dust-removing desulfurating apparatus bottom simultaneously, acid carries out neutralization reaction in alkaline substance in the waste water and the useless flue gas in dust-removing desulfurating apparatus, the flue gas up to standard through desulfurizing and purifying discharged by the air outlet, flue dust is sneaked into and is become buck in the water, buck flows into seperator of ash and water by the dust-removing desulfurating apparatus water outlet, water after precipitate and separate flows into coke powder adsorption filtration pond, after the adsorption filtration, reuse up to standard.Absorbent filter medium also can be used as the raw material reuse simultaneously.
The treatment of wastes with processes of wastes against one another of the present invention, technology is reasonable, and is easy and simple to handle, and the recyclable increment of water after the processing and filtrate is in desirable coking chemical waste water of a kind of pollution treatment synergic and the stack gases and administer technology.
Below in conjunction with process flow sheet embodiments of the invention are described in detail:
Fig. 1 is a process flow sheet of the present invention.
As shown in Figure 1 the technical process of present embodiment be with coking chemical waste water behind equalizing tank (1) homogeneous, squeeze in the dust-removing desulfurating apparatus through the water-in (4) on dust-removing desulfurating apparatus (3) top with sump pump (2), stack gases enters dust-removing desulfurating apparatus (3) from the gas approach (6) of dust-removing desulfurating apparatus bottom simultaneously, alkaline substance in the waste water and the acid in the waste gas carry out neutralization reaction in dust-removing desulfurating apparatus (3), dust-removal and desulfurizing, the flue gas up to standard through desulfurizing and purifying discharged by air outlet (5), flue dust is sneaked into and is become buck in the water, buck flows into seperator of ash and water (8) by dust-removing desulfurating apparatus water outlet (7), water after precipitate and separate flows into coke powder adsorption filtration pond (9), flow in the water collecting basin (10) through adsorption filtration water up to standard, for the sintering mill (plant) reuse.Absorbent filter medium also can be used as the raw material reuse simultaneously.
Claims (1)
1, in a kind of coking chemical waste water and the stack gases and administer technology, it is characterized in that coking chemical waste water behind equalizing tank (1) homogeneous, with sump pump (2) in water-in (4) fastener driving device on dust-removing desulfurating apparatus (3) top, simultaneously, stack gases is from gas approach (6) access to plant of dust-removing desulfurating apparatus (3) bottom, acid neutralization reaction in dust-removing desulfurating apparatus (3) in alkaline substance in the waste water and the useless flue gas, flue gas desulfurization purifies back up to standard and is discharged by air outlet (5), flue dust is sneaked in the water, buck flows into seperator of ash and water (8) through the water outlet (7) of dust-removing desulfurating apparatus (3), water after precipitate and separate flows into coke powder adsorption filtration pond (9), reuse after adsorption filtration is up to standard.
