Description

Technical Field

[0001] The utility model belongs to the technical field of VOCs gas treatment equipment, and particularly relates to an environmental protection equipment for secondary catalytic VOCs treatment. Background Art

[0002] VOCs, namely volatile organic compounds, are a class of organic compounds that are prone to volatilization at normal temperature; these compounds usually have relatively low boiling points and high vapor pressures, so they are easily converted from liquid or solid state to gaseous state and released into the air.

[0003] The sources of VOCs are very extensive, including natural sources and anthropogenic sources. At the same time, VOCs have potential hazards to human health and the environment.

[0004] In order to reduce the emissions and hazards of VOCs, people can take a series of control measures, such as adsorption method, absorption method, condensation method, combustion method, and biological treatment method, etc. However, the existing equipment only uses a single method for treatment, and the products of VOCs still need to be treated secondary. In this process, VOCs are prone to secondary volatilization, thus causing harm to the environment and human health. Therefore, we propose an environmental protection equipment for secondary catalytic VOCs treatment to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an environmental protection equipment for secondary catalytic VOCs treatment to solve the problems existing in the background art.

[0006] To achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0008] The cooling component includes a plurality of cooling ring pipes, each of the cooling ring pipes is tightly sleeved outside the cooling pipe, and the chassis abuts against the lowermost cooling ring pipe. A refrigerator is installed at the rear end of the L-shaped air inlet pipe, one end of the refrigerator is communicated with a water inlet pipe, the lower end of the refrigerator is communicated with a water outlet pipe, the lower end of the water outlet pipe is communicated with the uppermost cooling ring pipe, a connecting pipe is communicated between two adjacent cooling ring pipes, and a drain pipe is arranged on the lowermost cooling ring pipe.

[0009] A plurality of partition plates are provided inside the cooling pipe, and gaps are left between each partition plate and the inner wall of the cooling pipe, and the upper and lower adjacent gaps are arranged staggeredly.

[0010] Each of the partition plates is arranged in an inclined shape.

[0013] A plurality of mounting brackets are provided inside the combustion chamber, and activated carbon plates are placed on the upper ends of each mounting bracket.

[0014] Advantages of the present utility model:

[0015] 1. By providing a fan assembly, it can not only provide power for sucking VOCs, but also provide power for subsequent treatment of VOCs.

[0016] 2. By providing a cooling loop pipe, the cooling loop pipe can completely wrap the cooling pipe, so as to be able to cool and liquefy VOCs in all directions, and thus the VOCs can be preliminarily treated.

Specific implementation manners

[0025] In order to enable those skilled in the art to better understand the present utility model, the technical solution of the present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] Embodiment 1:

[0027] As Figures 1-3 shown, the secondary catalytic VOCs treatment environmental protection equipment includes an L-shaped intake pipe 100, and is characterized in that: the front end of the L-shaped intake pipe 100 is set to be open, a fan assembly 101 is installed inside the L-shaped intake pipe 100, the lower end opening of the L-shaped intake pipe 100 is hermetically connected to a cooling pipe 102, a cooling assembly is provided on the outer sides of the L-shaped intake pipe 100 and the cooling pipe 102, the lower end of the cooling pipe 102 is provided with a chassis 103, the middle of the lower end of the chassis 103 is communicated with a delivery pipe 104, the end of the delivery pipe 104 is communicated with a combustion chamber 105, and an exhaust pipe 106 is provided at the upper end of the combustion chamber 105.

[0028] The opening of the L-shaped intake pipe 100 is communicated with other equipment that generates VOCs. The fan assembly 101 can generate suction, which can not only quickly suck in the gas containing VOCs, but also push the gas containing VOCs to flow inside the equipment. When the gas enters the cooling pipe 102, relying on the cooling assembly, the gas containing VOCs can be cooled and liquefied, thereby realizing the preliminary treatment of VOCs. Then, the VOCs liquid is transported into the combustion chamber 105 through the delivery pipe 104 for combustion, so that the VOCs liquid can be subjected to secondary combustion treatment to prevent the volatilization of VOCs and cause damage to the environment and human health. The chassis 103 can support the cooling assembly and also facilitate the installation of the base. The base can raise the L-shaped intake pipe 100 and the cooling pipe 102, so that the cooled VOCs can directly fall under the action of its own gravity. The exhaust pipe 106 can discharge the finally generated carbon dioxide and water vapor.

[0029] After the device is connected: Start the fan assembly 101. The fan assembly 101 can suck in the gas containing VOCs and also push the gas containing VOCs to continue flowing. After the gas containing VOCs enters the cooling pipe 102, due to the action of the cooling component, the VOCs in the gas containing VOCs can be liquefied. Then the VOC liquid will be transported through the transport pipe 104 to the inside of the combustion chamber 105 for combustion, and finally it can be discharged.

[0030] In this embodiment: Through the fan assembly 101, not only can VOCs be sucked in, but also the gas containing VOCs can be made to flow. During the flow of the gas containing VOCs, the cooling component can perform a preliminary treatment of cooling and liquefying the VOCs. Then, through the combustion chamber 105, a secondary treatment of burning the VOC liquid is carried out, so that the VOCs can be fully treated to prevent the secondary volatilization of VOCs and cause harm to the environment and human health.

[0031] Embodiment Two:

[0032] As Figures 1-3 shown, on the basis of Embodiment One, other components on the secondary catalytic VOC treatment environmental protection equipment are further described. The cooling component includes a number of cooling ring pipes 200. Each cooling ring pipe 200 is tightly sleeved on the outside of the cooling pipe 102, and the chassis 103 abuts against the lowermost cooling ring pipe 200. A refrigerator 201 is installed at the rear end of the L-shaped intake pipe 100. One end of the refrigerator 201 is connected to a water inlet pipe 202, and the lower end of the refrigerator 201 is connected to a water outlet pipe 203. The lower end of the water outlet pipe 203 is connected to the uppermost cooling ring pipe 200. A connecting pipe 204 is connected between two adjacent cooling ring pipes 200. A drain pipe 205 is provided on the lowermost cooling ring pipe 200.

[0033] A number of partitions 300 are provided inside the cooling pipe 102, and there are gaps between each partition 300 and the inner wall of the cooling pipe 102, and the upper and lower adjacent gaps are arranged staggeredly.

[0034] Each partition 300 is set to be inclined.

[0035] The middle part of the transport pipe 104 is set to be curved.

[0036] A combustion plate 301 is hermetically provided inside the combustion chamber 105, and the combustion plate 301 is located below the communication port of the transport pipe 104.

[0037] A number of mounting frames 302 are provided inside the combustion chamber 105, and activated carbon plates 303 are placed on the upper ends of each mounting frame 302.

[0038] In this embodiment: At the place where the water inlet pipe 202 is connected to the water source, water can enter the cooler 201 through the water inlet pipe 202. The cooler 201 can cool the incoming water. Then, the ice water enters the inner part of the uppermost cooling loop pipe 200 through the water outlet pipe 203. Since each cooling loop pipe 200 is connected by the connecting pipe 204, the ice water will flow through the inner parts of each cooling loop pipe 200 and finally be discharged from the drain pipe 205. Also, since each cooling loop pipe 200 is in contact with the outer side of the cooling pipe 102, the gas inside the cooling pipe 102 can be cooled, and thus the gas of VOCs can be preliminarily treated.

[0039] Each partition plate 300 is set to be inclined, which facilitates the liquefied VOCs gas to directly slide down along each partition plate 300. And since the gaps between each partition plate 300 and the inner wall of the cooling pipe 102 are arranged staggeredly, the time for the gas containing VOCs to flow through the inside of the cooling pipe 102 can be increased, thereby cooling and liquefying the VOCs gas.

[0040] When the bent delivery pipe 104 delivers the VOCs liquid, as shown in the figure, it can prevent the VOCs liquid from flowing back or blocking the inside of the cooling pipe 102. At the same time, the delivery pipe 104 can also deliver the VOCs liquid into the combustion chamber 105.

[0041] The combustion plate 301 can burn the VOCs liquid, thereby decomposing it into carbon dioxide and water vapor, which can prevent the secondary volatilization of VOCs.

[0042] The mounting frame 302 can facilitate the placement of the activated carbon plate 303. The activated carbon plate 303 can filter the gas generated by the burned VOCs liquid, preventing the gas from entering the air and causing damage to the atmospheric environment and harm to human health.

[0043] The above embodiments only exemplarily illustrate the principles and effects of the present invention, rather than limiting the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present invention should still be covered by the claims of the present invention.
