The carrier gas channel and the gas channel to be purified are connected to one end of the mixed gas channel, the other end of the mixed gas channel is connected with the water bath box 6, the background gas and the gas to be purified respectively flow in from the gas inlets 5 of the carrier gas channel and the gas channel to be purified and are merged into one path in the mixed gas channel, so that the gas mixing speed can be increased, and the gas can be uniformly output to the reactor. The mixed gas enters the water bath tank 6 through the mixed gas channel, and if the gas is not required to be water, the water in the water bath tank can be drained; the water bath has a heater to control the water vapor content of the incoming air by controlling the temperature of the water bath, thereby controlling the rate of reaction.
The shell of the current equalizer is provided with a water level window 2 for observing the water level in the water bath box 6, if the water quantity is insufficient, water can be injected inwards through the water injection valve 1 (the water injection valve is connected with a tap water pipe through an adapter), and the water injection valve 1 can be installed above the window 2. Accordingly, the water bath box 6 has a drain valve 3, which may be disposed below the window 2, for draining off the sewage left by the impurities dissolved in the water or reacted with the water.

One flow equalizer may have a plurality of exhaust assemblies 7, and when the exhaust assemblies 7 are not used, the air holes 8 may be blocked by plugs. The exhaust assembly 7 may be a flange.
Figure 6 shows a reactor comprising a number of degradation tubes, which may be arranged in a matrix, where all the gas to be purified is DBD degraded. The air inlet 11 of the degradation pipe is connected with the air hole of the flow equalizer through a corrosion-resistant air pipe (such as a Teflon air pipe)And 8, connecting the air outlet of the degradation pipe to the gas treatment chamber through a corrosion-resistant air pipe (such as a Teflon air pipe). The structure of the degradation tube adopts the prior art, such as a conventional double-layer cylindrical discharge tube, each tube is provided with a positive pole and a negative pole, and a layer of ceramic dielectric is covered on the tube to be used as dielectric barrier discharge material. Wherein the outer medium thickness is 2.5mm, the inlayer medium thickness is 2mm, and outer medium internal diameter is 20mm, has 6mm air gaps between the double-deck medium, and the reaction tube is long 300mm, and wherein the regional length of discharging is 200mm, and both sides have respectively reserved 5 cm's distance, guarantee the insulation distance. The negative electrode is a copper cylinder with a diameter of 4mm in the middle of the reaction tube. Two layers of sealing rings are arranged at the protruding parts at the two sides of the pipe, so that the air tightness of the pipe is ensured.

The transformer can generate a large amount of heat in the running process, so that the oil temperature in the transformer is rapidly increased, and therefore the oil hole in the top of the transformer is kept in an open state when the transformer is normally used, and the transformer accident caused by vaporization and expansion of oil is avoided. Should use the screw to tighten this oilhole when the transportation, avoid because vibrations or upset lead to transformer oil to spill, the polluted environment increases the cleaning work.
The gas treatment chamber is the most downstream part, and can collect the gas discharged from the gas outlet holes of all the degradation pipes together through a corrosion-resistant gas pipe (such as a Teflon gas pipe), and the gas is discharged from the gas outlet holes after being treated by a gas pool (an alkali liquid pool) in the gas treatment chamber. The gas treatment chamber is provided with at least one alkali liquor pool, for example, each reactor corresponds to one alkali liquor pool, gas discharged from four reactors is converged into four alkali liquor pools through the gas inlet pipe, and then the gas subjected to alkali liquor treatment is discharged through a corrosion-resistant gas pipe (such as a Teflon gas pipe) connecting the gas discharge hole and the alkali liquor pools.
In order to ensure a sufficient completeness of degradation and also to ensure the personal safety of the workers, the entire apparatus should be placed outdoors and the tightness of the apparatus should be closely monitored during use.
