Technical field
The present invention relates to field of Environment Protection, be specifically related to a kind of device of chlorine oxidation ADC blowing agent vent gas treatment.
Background technology
The production of traditional ADC blowing agent all adopts single still mode of production, adopt chlorine oxidation, in course of reaction, generate HCl, in tail gas, contain in a large number HCl gas and unreacted chlorine, the catalyst bromine that also contains a small amount of volatilization, and in course of reaction, generally all to need to keep in still by tail gas air-introduced machine be micro-vacuum state.Through water, absorb and remove HCl wherein, with the remaining chlorine of absorption such as caustic soda and bromine etc., in this process, understand loss catalyst and then have influence on carrying out smoothly of oxidation reaction again, reducing product quality, produce a large amount of sour, high oxidation wastewaters of containing simultaneously, cause catalyst attrition.
Summary of the invention
The object of the invention is to overcome the deficiency that prior art exists, and a kind of device of chlorine oxidation ADC blowing agent vent gas treatment is provided.
The object of the invention is to complete by following technical solution.The device of this chlorine oxidation ADC blowing agent vent gas treatment, comprises reactor, is provided with the agitator being connected with power set in reactor; The vomit pipe of described reactor is connected with the input of Venturi tube by circulating pump, the efferent duct of Venturi tube extends in reactor, one end of chloride gas phase pipeline extends to the upper position in reactor, the other end of chloride gas phase pipeline is connected with the input of Venturi tube, and the negative pressure flow producing in Venturi tube by slip is reactor inner top chlorine-containing gas again sucting reaction system and react; Chlorine inlet pipe extends in reactor.
In described reactor, be provided with refrigerant inlet pipe and refrigerant and go out pipe formation refrigerant circulation.
On described reactor, be provided with relief hole, by this relief hole, be connected with accident absorption tower.
The installation site of described Venturi tube is higher than reactor liquid level.
Beneficial effect of the present invention is: the present invention is emission not in process of production, has improved the service efficiency of chlorine, and the generation and the catalyst that have significantly reduced factory effluent do not run off.

Fig. 1 is structural representation of the present invention.
Description of reference numerals: reactor 1, refrigerant inlet pipe 2, refrigerant goes out pipe 3, vomit pipe 4, circulating pump 5, Venturi tube 6, chloride gas phase pipeline 7, relief hole 8, chlorine inlet pipe 9, agitator 10.
The specific embodiment
Below by the specific embodiment, the present invention is further elaborated, and embodiment understands the present invention better by help, but the present invention is not limited only to following embodiment.
As shown in Figure 1, the device of this chlorine oxidation ADC blowing agent vent gas treatment, comprises reactor 1, is provided with refrigerant inlet pipe 2 and refrigerant and goes out pipe 3 formation refrigerant circulations in described reactor 1, is provided with the agitator 10 being connected with power set in reactor 1; The vomit pipe 4 of described reactor 1 is connected with the input of Venturi tube 6 by circulating pump 5, the efferent duct of Venturi tube 6 extends in reactor 1, one end of chloride gas phase pipeline 7 extends to the upper position in reactor 1, the other end of chloride gas phase pipeline 7 is connected with the input of Venturi tube 6, by slip in the negative pressure of Venturi tube 6 interior mobile generations reactor 1 inner top chlorine-containing gas again sucting reaction system and react; Chlorine inlet pipe 9 extends in reactor 1.This device is to utilize circulating pump to play circulation outward at reactor by slip, Venturi tube is installed on circulating line, utilize the negative pressure of slip mobile generation in Venturi tube still inner top chlorine-containing gas again sucting reaction system, in reaction system, react, emission not in course of reaction, ADC slip after having reacted, puts into subsequent processing by vomit pipe.Matter Transfer pipe gets back to that the inherent liquid level of reactor is above or following all can.
Venturi tube is installed on circulating line, and Venturi tube can be installed one and also can be installed a plurality of.The material of this Venturi tube can comprise according to the different choice of oxidant the material of the corrosion resistants such as titanium, lining are moulded, plastics.
In chlorine oxidation process, in the gas phase of upper strata, contain in reactor and have neither part nor lot in HCl gas, the bromine gas overflowing in the chlorine of reaction and reactant liquor, suction by Venturi tube is also drawn into top tank air in most still in reactor again, reduce and consume, reduce exhaust emissions and vent gas treatment amount.
Get back in stills for air blowing with the mixed slip of oxidant, slurry outlet is in still below liquid level, but it is poor to guarantee that negative pressure that Venturi tube produces is enough to overcome in still liquid-level pressure.The setting height(from bottom) of Venturi tube can be higher or lower than liquid level in reactor, and preferably installation site is higher than liquid level in reactor.
On described reactor 1, be provided with relief hole 8, the in-built rupture pressure disc of establishing of relief hole 8, prevent in course of reaction the danger that the pressure causing due to side reaction raises and occurs, guarantee the safety of reaction system, relief hole 8 is connected with accident absorption tower (exhaust treatment system), as production accident, processes.
Finally, it should be pointed out that above example is only the more representational example of the present invention.Obviously, technical scheme of the present invention is not limited to above-mentioned example, can also have many distortion, and all distortion that those of ordinary skill in the art can directly derive or associate from content disclosed by the invention, all should think protection scope of the present invention.
