[0002] The waste gas in the photovoltaic industry is mainly generated in the links such as silicon wafer slicing production, solar cell production and solar cell module production. Its types include acid-base waste gas, organic waste gas, thermal exhaust and ordinary gas, dust-containing gas and flammable and explosive gas, etc. The waste gas contains a large amount of industrial wastes such as silane, phosphine and TMA. These wastes are directly discharged into the atmosphere, which will cause a lot of damage to the environment and do not meet the requirements of current environmental protection production. At present, the waste gas is mainly treated by reaction combustion. First, the waste gas is introduced into the reaction chamber of natural gas flames such as plasma flames for heating, and then a combustion-supporting gas is injected into the reaction chamber to make the flame burn more violently and react with the waste gas. Small particle impurities generated by combustion will be mixed into the waste gas after combustion.

[0003] When the existing waste gas treatment device treats the particulate impurities in the waste gas, it usually discharges the waste gas into the cleaning water, adsorbs the particulate impurities in the waste gas through the cleaning water, and then discharges the waste gas. However, this method makes the contact time between the waste gas and the cleaning water shorter, easily resulting in some particulate impurities in the waste gas not being adsorbed and precipitated by the cleaning water, thus reducing the problem of the waste gas treatment quality.

[0025] Referring to Figure 1-6 , a photovoltaic waste gas treatment device includes an adsorption box 1. The inner bottom wall of the adsorption box 1 is fixedly connected with a first shunt cylinder 2. The outer surface of the first shunt cylinder 2 is fixedly communicated with an intake pipe 3. One end of the intake pipe 3 penetrates and extends to the outer surface of the adsorption box 1. The outer surface of the first shunt cylinder 2 is fixedly communicated with a first shunt pipe 4 distributed in an annular array. A check valve is arranged in the first shunt pipe 4 to prevent the cleaning water from flowing into the first shunt cylinder 2. One end of the first shunt pipe 4 is fixedly connected with a first crushing cover 5. The outer surface of the adsorption box 1 is fixedly communicated with a diversion pipe 6. One end of the diversion pipe 6 penetrates and extends to the inside of the adsorption box 1;

[0026] A double-layer adsorption device is arranged inside the adsorption box 1, and the double-layer adsorption device includes a conical diversion cover 7. The outer surface of the conical diversion cover 7 is fixedly sleeved with the inner wall of the adsorption box 1.

[0027] Furthermore, a second flow dividing cylinder 71 is fixedly sleeved on the inner surface of the conical fairing 7. The outer surface of the second flow dividing cylinder 71 is fixedly communicated with a plurality of second flow dividing pipes 72 distributed in an annular array. A one-way valve is arranged in the second flow dividing pipe 72 to prevent the cleaning water from flowing into the second flow dividing cylinder 71.

[0028] Furthermore, one end of the second flow dividing pipe 72 is fixedly connected to a second crushing cover 73. The upper surface of the adsorption box 1 is fixedly communicated with an exhaust pipe 74. The lower surface of the adsorption box 1 is fixedly communicated with a return pipe 75. A filter screen is arranged at the upper end of the exhaust pipe 74 to further intercept particulate impurities in the gas. The second crushing cover 73 divides the bubbles into a plurality of small bubbles through a plurality of blocking strips, so as to facilitate the cleaning water to adsorb the particulate impurities in the waste gas.

[0029] Furthermore, one end of the return pipe 75 is fixedly communicated with a circulating water tank 76. The upper surface of the circulating water tank 76 is in contact with the lower surface of the adsorption box 1. The front surface of the circulating water tank 76 is fixedly communicated with a water injection pipe 77, which is convenient for adding cleaning water into the circulating water tank 76.

[0030] Furthermore, a sealed filter frame 78 is movably inserted into the front surface of the circulating water tank 76. A filter screen 79 is fixedly sleeved on the inner wall of the sealed filter frame 78. The filter screen 79 intercepts particulate impurities in the cleaning water. A handle is arranged on the front surface of the sealed filter frame 78, which is convenient for taking out and replacing for cleaning.

[0031] Furthermore, a submersible pump 710 is fixedly installed on the inner bottom wall of the circulating water tank 76. The water outlet end of the submersible pump 710 is fixedly communicated with a water outlet pipe 711. The submersible pump 710 pumps out the water in the circulating water tank 76 through the water outlet pipe 711.

[0032] Furthermore, one end of the water outlet pipe 711 penetrates through the circulating water tank 76 and extends into the interior of the adsorption box 1. A liquid level sensor 712 is fixedly installed on the inner wall of the adsorption box 1, which monitors the injection liquid level of the cleaning water inside the adsorption box 1.

[0033] By setting the double-layer adsorption device, the bubbles generated by the waste gas in the water are broken, and the bubbles are divided into a plurality of small-volume bubbles, so as to facilitate the cleaning water to fully adsorb the particulate impurities in the waste gas. And through double-layer adsorption, the adsorption effect on the particulate impurities in the waste gas is greatly improved, thus improving the waste gas treatment quality.

[0034] Working principle: Step 1, the conical deflector 7 serves to divide the adsorption box 1 into upper and lower layers. When the submersible pump 710 works, the submersible pump 710 transports the cleaning water in the circulation water tank 76 to the upper layer of the adsorption box 1 through the water outlet pipe 711. The water in the upper layer of the adsorption box 1 continuously flows into the bottom of the lower layer of the adsorption box 1 through the diversion pipe 6. At this time, the water injection speed of the submersible pump 710 is greater than the flow rate of the diversion pipe 6. When the liquid level sensor 712 monitors that the water level in the upper layer of the adsorption box 1 reaches the preset value, the power of the submersible pump 710 is reduced to keep the same flow rate as the diversion pipe 6;

[0035] Step 2, the waste gas is transported to the inside of the first shunt cylinder 2 through the intake pipe 3, and then the waste gas is transported to the cleaning water in the lower layer of the adsorption box 1 through multiple first shunt pipes 4. The ejection of the waste gas will generate bubbles in the cleaning water, and the generated bubbles are broken by the first crushing cover 5 to form multiple small-volume bubbles. During the process of the bubbles rising in the cleaning water, the cleaning water adsorbs the particulate impurities in the bubbles and precipitates them by their own weight;

[0036] Step 3, after the bubbles rise to the surface of the lower-layer cleaning water, the waste gas is guided by the conical deflector 7 to enter the second shunt cylinder 71, and then is transported to the cleaning water in the upper layer of the adsorption box 1 through multiple second shunt pipes 72, and is broken by the second crushing cover 73 to form multiple small-volume bubbles. The upper-layer cleaning water adsorbs and precipitates the particulate impurities in the small-volume bubbles again to further remove the particulate impurities in the bubbles. Finally, the waste gas is discharged through the exhaust pipe 74;

[0037] Step 4, the particulate impurities in the upper-layer cleaning water flow into the lower-layer cleaning water through the diversion pipe 6. The impurity particles in the lower-layer cleaning water are transported to the circulation water tank 76 through the return pipe 75, and then the particulate impurities are filtered and intercepted by the filter net 79, so that the cleaning water flows into the bottom of the circulation water tank 76 for recycling after filtration. The staff can take out the sealed filter frame 78 to clean the particulate impurities on the filter net 79 and then continue to use it.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered by the scope of the claims and the description of the present invention.
