[0004] In the above method, an atomizing spray mechanism and a nano-microbubble generating mechanism are arranged in the tower body of the superoxide nano-microbubble device.

However, the treatment effect of the organic waste gas is relatively poor. Utility Model Content

DETAILED DESCRIPTION

[0019] The utility model is further described in detail below through specific implementation methods:

[0020] like Figure 1 and Figure 2 As shown, an embodiment of the utility model proposes an organic waste gas treatment device, comprising a shell 1, an atomizing spray system 2 and a nano bubble water generating system 3; wherein the shell 1 has an air inlet and an exhaust port, and a spray reaction zone 11, a filler reaction zone 12, a demisting zone 13 and an activated carbon adsorption zone 14 are arranged in sequence from the air inlet to the exhaust port in the shell 1; the atomizing spray system 2 cooperates with the spray reaction zone 11 and the filler reaction zone 12 to provide nano bubble mist; the nano bubble water generating system 3 is connected to the atomizing spray system 2 to provide nano bubble water for the atomizing spray system 2.

[0021] In this scenario:

[0022] The organic waste gas enters the shell 1 from the air inlet, and passes through the spray reaction zone 11, the filler reaction zone 12, the demisting zone 13 and the activated carbon adsorption zone 14 in sequence; because the atomizing spray system 2 cooperates with the spray reaction zone 11 and the filler reaction zone 12, the nano bubble water generated by the nano bubble water generating system 3 is sprayed into the spray reaction zone 11 and the filler reaction zone 12 in an atomized manner through the atomizing spray system 2, and the organic waste gas entering the shell 1 undergoes two-stage oxidation decomposition in the spray reaction zone 11 and the filler reaction zone 12, and then enters the demisting zone 13 for demisting, and then enters the activated carbon adsorption zone 14 for efficient active adsorption, so as to complete the purification of the organic waste gas, and the purified gas is discharged from the exhaust port.

[0023] like Figure 1 and Figure 2 As shown, according to another embodiment of the utility model, the organic waste gas treatment device, wherein the nano bubble water generating system 3 includes a first water tank 31, a nano bubble generator 32 and a second water tank 33; wherein the first water tank 31 is provided with a water inlet and is also connected to the spray reaction zone 11 and the filler reaction zone 12; the nano bubble generator 32 is connected to the first water tank 31; the second water tank 33 is connected to the nano bubble generator 32, and the second water tank 33 is also connected to the atomization spray system 2.

[0024] The specific process of nano bubble water production is:

[0025] The tap water enters the first water tank 31 from the water inlet for storage, so as to ensure that the tap water stably enters the nano bubble generator 32 to generate nano bubble water. The generated nano bubble water is specifically introduced into the second water tank 33 for storage through the lifting pump 34. The nano bubble water stored in the second water tank 33 is atomized by the atomizing spray system 2, and then enters the spray reaction area 11 and the filler reaction area 12 for use. The nano bubble water after the reaction in the spray reaction area 11 and the filler reaction area 12 is returned to the first water tank 31 for reuse, thereby reducing the waste of water resources.

[0026] The second water tank 33 is a high-position water tank and is arranged on the top of the housing 1. The nano bubble water stored in the second water tank 33 enters the atomizing spray system 2 for atomization under the pressure difference caused by the height, and is arranged reasonably to reduce the loss of electric energy.

[0027] like Figure 1 As shown, according to another embodiment of the utility model, the organic waste gas treatment device, wherein the atomizing spray system 2 includes a spray pipe 21 and an atomizing fan 22; wherein the spray pipes 21 are provided in a plurality and are distributed in the spray reaction zone 11 and the filler reaction zone 12, and the atomizing fan 22 is connected between the nano bubble water generating system 3 and each spray pipe 21.

[0028] Specifically, the atomizing fan 22 is connected to the high-level water tank through a pipeline, and the nano bubble water in the high-level water tank is atomized by the atomizing fan 22, and then enters each spray pipe 21 to be sprayed into the spray reaction area 11 and the filler reaction area 12. Among them, the spray pipe 21 is arranged with multiple nozzles at intervals along its axial direction.

[0029] like Figure 1 and Figure 2 As shown, according to another embodiment of the utility model, in the organic waste gas treatment device, the exhaust port is connected to an exhaust pipe 4, and the exhaust pipe 4 is connected to a chimney 5.

[0030] The purified gas enters the air outlet pipe 4 and is then discharged into the atmosphere through the chimney 5; wherein, the air outlet pipe 4 is also provided with a suction fan 6; the suction fan 6 provides power for the organic waste gas to enter the shell 1 and flow in the shell 1, so as to efficiently drive the organic waste gas to be purified in the shell 1 and then discharged into the atmosphere through the chimney 5.

[0031] like Figure 1As shown, according to another embodiment of the utility model, an organic waste gas treatment device is described, wherein the filler reaction zone 12 is filled with a polymer composite filler, and the nano bubble water is fully atomized and attached to the polymer composite filler in the filler reaction zone 12. Since the specific surface area of ​​the filler is very large, the gas-liquid mass transfer efficiency will be greatly enhanced, and the organic waste gas will be further oxidatively decomposed.

[0032] like Figure 1 As shown, according to another embodiment of the utility model, a demister 7 is provided in the demister area 13 of the organic waste gas treatment device. The demister 7 is used in the demister area 13 to demister the organic waste gas after oxidation and decomposition in the filler reaction area 12, so as to prevent the atomized water from being brought into the activated carbon adsorption area 14 by the organic waste gas to affect the adsorption efficiency.

[0033] like Figure 1 As shown, according to another embodiment of the utility model, in the organic waste gas treatment device, the activated carbon adsorption area 14 is filled with activated carbon. The organic waste gas entering the activated carbon adsorption area 14 is adsorbed by the activated carbon, and the organic pollutants in the organic waste gas are adsorbed by the activated carbon and introduced into the chimney 5 through the outlet pipe 4 for discharge.

[0034] When this organic waste gas treatment device is used:

[0035] Under the action of the suction fan 6, the organic waste gas enters the shell 1 from the air inlet, and then the organic waste gas is subjected to a primary oxidation decomposition in the spray reaction zone 11, and then enters the filler reaction zone 12 for a secondary oxidation decomposition, and then passes through the demisting zone 13 for demisting treatment, and then enters the activated carbon adsorption zone 14 for active adsorption to complete the purification of the organic waste gas; the treatment efficiency of the organic waste gas reaches more than 99.9%, and the emission meets the standard, and then is discharged from the chimney 5.

[0036] The organic waste gas treatment device can cooperate with the existing central control system to perform automatic control and improve operation efficiency.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
