Drawings
FIG. 1 is a schematic block diagram of one embodiment of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
As shown in fig. 1, a chemical waste gas treatment system comprises a condensation separator, a catalytic absorber, an acid and alkali washing device, a cyclone demister, a microwave photoelectrocatalysis oxidation device, a fan device and an activated carbon adsorber which are sequentially communicated through a waste gas pipeline.
The condensation separator, the catalytic absorber, the acid and alkali washing device, the cyclone demister, the microwave photoelectrocatalysis oxidation device and the fan device are connected with a controller together. The controllers are all PLC. The purpose of PLC is to realize automated control, and PLC is the mature product in the market, and the purchase is convenient, and the technical staff also can easily master.
The condensation separator comprises a condensation shell, a heat exchanger is arranged in the condensation shell, and the heat exchanger is communicated with an external cold water source container; and a water pump is arranged on a pipeline between the heat exchanger and the cold water source container. The condensation separator is used for condensing and separating the high-concentration organic waste gas, and the load of a subsequent treatment process is reduced.
The catalytic absorber comprises a catalytic converter shell, a catalytic water tank is arranged in the catalytic converter shell, and water with a catalyst is contained in the catalytic water tank; the intake pipe of the exhaust gas line on the catalyst housing is inserted into the water. When the waste gas passes through the catalytic absorber, the catalyst catalyzes the hydration of ethylene oxide, thereby facilitating the absorption.
The acid washing and alkali washing equipment comprises an acid washing tower and an alkali washing tower which are communicated in sequence. The organic matters in the waste gas are further separated through acid washing and alkali washing. The ammonia waste gas in the waste gas can be removed by acid washing, and the hydrogen sulfide gas in the water can be removed by alkali washing, so that the concentration of pollutants in the waste gas is reduced.
Through the whirl defroster, get rid of the moisture in the waste gas, prevent that the moisture in the waste gas from being adsorbed by active carbon, influencing the adsorption efficiency of waste gas.
The microwave photoelectrocatalysis oxidation device comprises a catalytic oxidation shell, wherein a photolysis area and a photocatalytic oxidation area are arranged in the catalytic oxidation shell according to the flowing direction of waste gas. An electrodeless lamp is arranged in the photolysis area. And a ceramic catalytic plate is arranged in the photocatalytic oxidation area. The ceramic catalytic plate is prepared by solidifying a nano photocatalyst on a honeycomb ceramic substrate in a sintering mode. The microwave photoelectrocatalysis oxidation equipment mainly utilizes 'microwave plasma strong electromagnetic field, special light source and photocatalyst' to efficiently crack organic molecules in waste gas under the synergistic action of multiple effects, so that malodorous gas is instantly converted into colorless and odorless stable and harmless oxides such as carbon dioxide, water and the like, and the purposes of deodorization and purification are achieved. The principle of the technology is colloquially called energy time conversion, and most of the reaction can be completed within 1 s.
The fan device uses a centrifugal fan. The released organic waste gas is captured to the waste gas treatment system under the action of the fan. After the concentration of the waste gas is very low after the previous concentrated treatment process, the waste gas is conveyed to an activated carbon adsorber by a fan for further purification treatment.
The activated carbon adsorber comprises an activated carbon adsorption box and an activated carbon filter screen arranged in the activated carbon adsorption box; the activated carbon adsorption box adopts a fixed bed type structure, and the diameter of the activated carbon adsorption box is 2000 mm. After the activated carbon adsorption device operates for a period of time, the purification efficiency of the activated carbon adsorption device can be reduced to a certain limit value, and the exhaust emission does not reach the standard at the moment, so that the activated carbon of the adsorption bed needs to be replaced. The specific replacement period is determined according to the actual use condition, and the replacement period is six months under the general condition.
The system sequentially carries out processes of condensation separation, catalytic absorption, acid washing, alkali washing, cyclone demisting, microwave photoelectrocatalysis oxidation, activated carbon adsorption and the like on the waste gas, ensures that the waste gas meets the environmental protection requirement when being discharged, and has the advantages of small equipment volume, low operation cost and long service cycle.
