Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The first embodiment is as follows:
as shown in fig. 1 and fig. 4, a paint spraying waste gas treatment system comprises a cyclone tower 1, an absorber 2 and a chimney 3, wherein a waste gas inlet 15 is arranged at a position close to the bottom of the cyclone tower 1, the top of the cyclone tower 1 is communicated with the top of the absorber 2 through a communicating pipe 6, a waste gas outlet 24 is arranged at a position close to the top of the absorber 2, the waste gas outlet 24 is communicated with the chimney 3 through a fan 4, and thus purified waste gas can be discharged aloft along the chimney 3.
As shown in the attached drawings 1 to 3, a plurality of cyclone plates 11 are arranged in the cyclone tower 1 from top to bottom, the number of the cyclone plates 11 can be determined according to actual conditions, and the number of the cyclone plates 11 is three. After waste gas enters into whirl tower 1 like this, waste gas will upwards move and pass whirl board 11 to can produce whirlwind when leaving whirl board 11, thereby the magazine granule that carries in the waste gas will be thrown to the tower wall, and tower wall department is because wind-force is relatively weak, so impurity and granule will be along the tower wall landing, have just so realized just also the edulcoration operation to waste gas.
In addition, a plurality of spray headers 12 are arranged between every two adjacent rotational flow plates 11, and the spray headers 12 are arranged in a straight row. The spray head 12 is communicated with a circulating water tank 5 filled with absorption liquid from the outside through a water pump 51, and the circulating water tank 5 is filled with water and polyethylene glycol, wherein the volume ratio of the water to the polyethylene glycol is 6: 1, so that the absorption effect of the water on harmful gas is favorably improved with the help of the polyethylene glycol, and the environmental protection cost is favorably reduced. Therefore, when the spray header 12 sprays the absorption liquid into the waste gas, on one hand, the cyclone helps the absorption liquid to be quickly mixed with the harmful gas in the waste gas, and the absorption effect of the absorption liquid on the harmful gas in the waste gas is improved. On the other hand, after the absorption liquid absorbs the harmful gas, the absorption liquid can be thrown to the wall of the tower through the cyclone, so that the obstruction of the absorption liquid to the waste gas through the cyclone plate 11 can be reduced, and meanwhile, impurities and particles attached to the peripheral surface of the wall of the tower can be taken away in the process that the absorption liquid flows down along the wall of the tower, so that the cleanness of the cyclone tower 1 can be kept.
Meanwhile, the bottom of the cyclone tower 1 is also communicated with the circulating water tank 5, so that the used absorption liquid is gathered in the circulating water tank 5, the recycling rate of the absorption liquid is improved, and the waste of the absorption liquid can be reduced.
As shown in fig. 4 and 5, three layers of mesh plates 21 are arranged inside the adsorber 2, and activated carbon is filled between two adjacent layers of mesh plates 21 to form an activated layer, wherein the activated carbon layer 22 at the upper layer is honeycomb activated carbon, and the activated carbon at the lower layer is annular activated carbon. In addition, the communicating pipe 6 enters the outlet at one end inside the adsorber 2, which penetrates all the activated carbon layers and the screen 21, and the outlet of the communicating pipe 6 is gradually enlarged from top to bottom. Meanwhile, the cross section of the adsorber 2 is also provided with baffle plates 23 between the outlet of the communicating pipe 6 and the lowest mesh plate 21, and the vertical section of each baffle plate 23 is trapezoidal.
After the waste gas comes out from the communicating pipe 6, the flow velocity of the waste gas is obviously reduced, so that the waste gas can be in contact with the baffle plate 23 for a sufficient time, the aerial fog of the absorption liquid in the waste gas can be condensed on the baffle plate 23 and flows downwards to the bottom of the adsorber 2 along the baffle plate 23, and the adsorber 2 is dried, so that the dryness of the activated carbon can be ensured when the waste gas passes through the activated carbon, the long-acting adsorption performance of the activated carbon can be maintained, and the waste gas discharged from the waste gas outlet 24 of the adsorber 2 can reach the standard of environmental protection.
Moreover, a condenser 61 is arranged at the position of the communicating pipe 6 close to the outlet, and when the waste gas passes through the condenser 61, the temperature of the aerial fog of the absorption liquid is reduced and condensed, so that the efficiency of removing the absorption liquid in the waste gas is further improved, and the dryness of the activated carbon block is also favorably ensured.
Example two:
as shown in fig. 6 and 7, based on the first embodiment, a guiding cover 13 is further disposed between the air outlet direction of each of the swirling plates 11 and the shower head 12, the guiding cover 13 is in a circular truncated cone shape, the upper and lower bottom surfaces of the guiding cover 13 penetrate through, and the lower edge of the guiding cover 13 is fixed to the tower wall of the swirling tower 1. Here, there is also a slit between the baffle and the column wall to facilitate the absorption liquid flowing down along the outer surface of the baffle 13. In addition, in the rising process of the waste gas, the waste gas is concentrated at the upper opening of the air guide sleeve 13, so that the concentration of harmful gas at the upper opening of the air guide sleeve 13 is increased, and the absorption efficiency of the absorption liquid and the harmful gas in the waste gas is improved.
Furthermore, the inner surface of the air guide sleeve 13 is coated with Cu-Mn-Ce/TiO2A molecular sieve catalyst 131, and a UV lamp 132 is installed on the inner surface of the pod 13 such that when the exhaust gas flows along the pod 13, the UV lamp 132 generates ultraviolet light, which catalyzes Cu-Mn-Ce/TiO2The molecular sieve catalyst 131 photocatalytically oxidizes the harmful gas and generates water and carbon dioxide, thus improving the purification efficiency of the harmful gas.
Furthermore, in order to reduce the contact of the absorption liquid to the Cu-Mn-Ce/TiO on the inner wall of the air guide sleeve 132 Molecular sieve catalyst 131 and UV lamp 132, so that the edge of the upper opening of the pod 13 is turned down to form a rim 133, so that the absorption liquid falling on the edge of the upper opening of the pod 13 flows down along the rim 133, thereby also advantageously avoiding the absorption liquid from directly contacting with Cu-Mn-Ce/TiO2 Molecular sieve catalyst 131 and UV lamp 132.
In addition, an overflow plate 14 is further arranged between the swirl plate 11 and the lower spray header 12, the overflow plate 14 is in a circular truncated cone shape, and an overflow hole 141 is further formed in the middle height of the overflow plate 14, so that the absorption liquid can be converged into the overflow plate 14 after flowing through the swirl plate 11, when the liquid level of the absorption liquid reaches the overflow hole 141, the absorption liquid can overflow from the overflow hole 141, and the exhaust gas needs to flow into the overflow plate 14 from the overflow hole 141, so that the exhaust gas and the absorption liquid can form convection, and the absorption effect of harmful gas in the exhaust gas can be improved.
Here, five groups of painting waste gases with different contents of harmful gases were passed through a painting waste gas treatment system, and the purified waste gases were finally detected, with the following table results:
it can be seen from the data before and after purification that this exhaust treatment system that sprays paint has stronger purification performance to the waste gas that sprays paint, therefore is fit for most coating production and the enterprise of construction and makes the installation use.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
