This exhaust treatment device is used in coking production adopts burnt oil filter, sulfuric acid scrubbing tower, sodium hypochlorite tower and desulfurizing tower to and the form of spray scrubber and the inter combination of active carbon adsorption jar, simple structure easily realizes, has reduced the running cost by a wide margin, is showing and is improving the exhaust -gas treatment effect.
Description
Technical field
This utility model relates to a kind of emission-control equipment, specifically a kind of coking production emission-control equipment.
Background technology
The waste gas produced in coking production industry contains multiple harmful substances, need the waste gas of discharge is progressively processed, to reach discharge standard, it is wherein one important step in exhaust-gas treatment for the exhaust-gas treatment containing tar, and tar emission-control equipment structure of the prior art is complicated, operating cost is high, and tar removal effect is unsatisfactory, if the tar in waste gas can not get eradicating and entering in air, it will brings serious environmental pollution.Exhaust-gas treatment without tar is then needed individually separately to set a set of processing means, relatively costly, and be difficult to reach preferable treatment effect.
Utility model content
The problem existed for above-mentioned prior art, this utility model provides a kind of coking production emission-control equipment, simple in construction, it is easy to accomplish, operating cost is cheap, significantly improves the exhaust-gas treatment effect in coking production.
To achieve these goals, this coking production includes tar filter, sulfuric acid scrubbing tower, hypochlorite oxidation tower and the desulfurizing tower being sequentially communicated with emission-control equipment；
And it is connected to the spray scrubber after described desulfurizing tower and absorbent charcoal adsorption tank；
Described absorbent charcoal adsorption tank connects aiutage by blower fan.
Further, described hypochlorite oxidation tower is contained within sodium hypochlorite filler and efficient fog remover.
Further, described absorbent charcoal adsorption tank uses modular activated carbon frame, filling cylindricality activated carbon in carbon frame.
Further, described spray scrubber is made up of filler, spray equipment and demister.
Compared with prior art, this coking production emission-control equipment uses tar filter, sulfuric acid scrubbing tower, hypochlorite oxidation tower and desulfurizing tower, and the form that spray scrubber be combined with each other with absorbent charcoal adsorption tank, simple in construction, it is easily achieved, significantly reduce operating cost, significantly improve exhaust-gas treatment effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described further.
As it is shown in figure 1, this coking production includes tar filter, sulfuric acid scrubbing tower, hypochlorite oxidation tower and the desulfurizing tower being sequentially communicated with emission-control equipment；
And it is connected to the spray scrubber after described desulfurizing tower and absorbent charcoal adsorption tank；
Described absorbent charcoal adsorption tank connects aiutage by blower fan.
This coking production is as follows by the operation principle of emission-control equipment:
Waste gas containing tar is by the metal gauze in high-speed impact tar filter during tar filter, by tar retention in tar filter, tar is removed, harmful gas absorption, by spray scrubber washing cleaning, is ultimately discharged into air finally by absorbent charcoal adsorption tank by subsequent gases.
In other waste gas without tar, ammonia is by sulfuric acid absorption in sulfuric acid scrubbing tower, and reaction equation is NH3+H2SO4=NH4HSO4, in subsequent gases, hydrogen sulfide and hydrocyanic acid carry out hypochlorite oxidation process, H inside hypochlorite oxidation tower2S+4NaClO=H2SO4+ 4NaCl, meanwhile, hydrocyanic acid is removed by hypochlorite oxidation in the basic conditions, it is possible to achieve the complete oxidation of CN-is removed.Waste gas, by can be with part sodium hypochlorite taste after hypochlorite oxidation tower, owing to sodium hypochlorite taste is pungent, adds spray scrubber in sodium hypochlorite washing rear end, can be used for removing sodium hypochlorite taste.
Sulphur-containing exhaust gas passes sequentially through desulfurizing tower and absorbent charcoal adsorption tank realizes the desulfurization of waste gas, significantly improves desulfurized effect.
Further, described hypochlorite oxidation tower is contained within sodium hypochlorite filler and efficient fog remover.Can effectively remove the hydrogen sulfide in gas and hydrocyanic acid, it is possible to achieve the complete oxidation of CN-is removed.
Further, described absorbent charcoal adsorption tank uses modular activated carbon frame, filling cylindricality activated carbon in carbon frame.Using diameter 4～8 column-shaped active carbon, activated carbon specific surface area and porosity is big, and high adsorption capacity has preferable mechanical strength, chemical stability and heat stability, and purification efficiency is up to 95%.Organic exhaust gas passes through adsorbent bed, contacts with activated carbon, and the organic pollution in waste gas is attracted to activated carbon surface, thus spins off from air-flow, reaches clean-up effect.The air-flow discharged from activated carbon adsorption bed has reached discharge standard, and air can directly discharge.
Further, described spray scrubber is made up of filler, spray equipment and demister.Realize the washing cleaning function removing the follow-up gas of tar.
In sum, this coking production emission-control equipment uses tar filter, sulfuric acid scrubbing tower, hypochlorite oxidation tower and desulfurizing tower, and the form that spray scrubber be combined with each other with absorbent charcoal adsorption tank, simple in construction, it is easily achieved, significantly reduce operating cost, significantly improve exhaust-gas treatment effect.
