Description

Technical Field

[0001] This application relates to the field of soil remediation technology, and in particular to a soil pyrolysis gas cooling treatment device. Background Technology

[0002] In the process of soil remediation, pyrolysis technology is often used to treat contaminated soil. During the pyrolysis process, a large amount of pyrolysis gas is generated. This pyrolysis gas contains a variety of harmful substances, such as volatile organic compounds and tar, which need to be cooled and purified before they can be discharged or further utilized.

[0003] Currently, existing soil pyrolysis gas cooling treatment equipment has the following shortcomings: low cooling efficiency, unable to quickly cool the pyrolysis gas to a suitable temperature; during the cooling process, impurities in the pyrolysis gas are prone to clogging the equipment, affecting its normal operation. Therefore, a soil pyrolysis gas cooling treatment equipment is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a soil pyrolysis gas cooling and treatment device to solve the problems mentioned in the background art.

[0005] The soil pyrolysis gas cooling treatment equipment provided in this application adopts the following technical solution:

[0006] A soil pyrolysis gas cooling treatment device includes a cooling box. The inner wall of the cooling box is fixedly connected with a cooling pipe by a plurality of fixing plates. The cooling pipe has a serpentine design, with both ends extending out of the outside of the cooling box. A cooling component is installed on the bottom outer wall of the cooling box.

[0007] The cooling assembly includes a thermoelectric cooler, heat-conducting fins, and a cooling fan. The thermoelectric cooler is fixedly installed on the bottom inner wall of the cooling box by bolts. Multiple heat-conducting fins are fixedly connected to the bottom outer wall of the thermoelectric cooler in an equally spaced array, with their bottom ends extending out of the cooling box. Two cooling fans are fixedly installed on the bottom outer wall of the cooling box to blow air convection into the gaps formed by the multiple heat-conducting fins.

[0008] Preferably, a filter cartridge is fixedly connected to one side of the outer wall of the cooling box via a mounting bracket. The outer wall of the filter cartridge is symmetrically provided with an air inlet and an exhaust outlet, and the exhaust outlet is connected to one end of the cooling pipe.

[0009] Preferably, an interceptor cylinder is installed inside the filter cartridge. The top of the interceptor cylinder is inclined and the inclined surface faces the air inlet. A mounting plate is detachably installed on the top of the filter cartridge, and the mounting plate is fixedly connected to the interceptor cylinder through a connecting bracket.

[0010] Preferably, a sealing rubber gasket is provided between the semiconductor refrigeration chip and the inner wall of the cooling box, and the upper and lower outer walls of the sealing rubber gasket are tightly fitted to the semiconductor refrigeration chip and the cooling box.

[0011] Preferably, the bottom outer wall of the cooling box is fixedly connected with multiple support feet.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] 1. In the equipment, the cooling pipe adopts a serpentine design, which increases the flow path of pyrolysis gas in the cooling pipe and prolongs the contact time between pyrolysis gas and cooling medium. At the same time, with the cooling components, the semiconductor refrigeration chip can directly cool the air in the cooling box. The heat-conducting fins and the cooling fan work together to quickly dissipate the heat generated by the semiconductor refrigeration chip, further enhancing the cooling effect. This solves the problem of low cooling efficiency and inability to cool down quickly in existing equipment, and meets the temperature requirements for subsequent emission or utilization of pyrolysis gas.

[0014] 2. The equipment is equipped with a filter cartridge at the front end of the cooling pipe. The top of the interceptor cartridge inside the filter cartridge is inclined and the inclined surface faces the air inlet. After the pyrolysis gas enters the filter cartridge, it first contacts the inclined surface of the interceptor cartridge, which can effectively intercept impurities contained in the pyrolysis gas. At the same time, the interceptor cartridge is fixed to the detachable mounting top plate through the connecting frame, which makes it easy to remove the interceptor cartridge regularly to clean impurities and prevent impurities from entering the subsequent cooling pipe and cooling components and causing blockage. This solves the problem of existing equipment being affected by impurity blockage and improves the stability and service life of the equipment. Attached Figure Description

[0019] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0020] This application discloses a soil pyrolysis gas cooling and treatment device. (Refer to...) Figure 1-3A soil pyrolysis gas cooling treatment device includes a cooling box 1. The inner wall of the cooling box 1 is welded and fixed with multiple fixing plates 7. The cooling pipes 6 are made of copper and have a serpentine design. This design can increase the flow path of pyrolysis gas in the cooling pipes 6, thereby improving the cooling effect. Both ends of the cooling pipes 6 extend out of the cooling box 1. Cooling components are installed on the bottom outer wall of the cooling box 1. It should be noted that the outer wall of the cooling box 1 is provided with a liquid injection port and a liquid drainage port for cooling medium, which facilitates the replacement of the cooling medium inside the cooling box 1.

[0021] The cooling assembly includes a thermoelectric cooler 8, heat-conducting fins 9, and cooling fans 11. The thermoelectric cooler 8 is fixedly installed on the bottom inner wall of the cooling box 1 by four bolts. The cooling surface of the thermoelectric cooler 8 faces upward and contacts the cooling medium inside the cooling box 1 to achieve the cooling effect. Multiple heat-conducting fins 9 are welded and fixed to the bottom outer wall of the thermoelectric cooler 8 at equal intervals. The heat-conducting fins 9 are made of aluminum alloy and have good thermal conductivity. Their bottom ends extend out of the cooling box 1. Two cooling fans 11 are fixedly installed on the bottom outer wall of the cooling box 1 by bolts and are located on both sides of the heat-conducting fins 9 to blow air convection into the gaps formed by the multiple heat-conducting fins 9 to accelerate heat dissipation.

[0022] A filter cylinder 2 is fixedly connected to one side of the outer wall of the cooling box 1 by bolts through a mounting bracket 12. The mounting bracket 12 is made of angle steel to ensure the stability of the filter cylinder 2 installation. The outer wall of the filter cylinder 2 is symmetrically provided with an air inlet 201 and an exhaust outlet 202. The air inlet 201 is connected to the soil pyrolysis gas generating device through a pipe, and the exhaust outlet 202 is connected to one end of the cooling pipe 6 through a pipe, so that the filtered pyrolysis gas can enter the cooling pipe 6 for cooling.

[0023] Inside the filter cartridge 2 is an interceptor cartridge 3, which is made of stainless steel and has filter holes evenly distributed on its surface. The top of the interceptor cartridge 3 is inclined and the inclined surface faces the air inlet 201. This design allows the pyrolysis gas to come into contact with the inclined surface of the interceptor cartridge 3 first after entering the filter cartridge 2, thereby improving the effect of intercepting impurities. The top of the filter cartridge 2 is detachably mounted with a mounting plate 4 by a buckle. The mounting plate 4 is welded and fixed to the interceptor cartridge 3 by a connecting bracket 5. When it is necessary to clean the interceptor cartridge 3, the mounting plate 4 can be opened and the interceptor cartridge 3 can be taken out.

[0024] A sealing rubber gasket 10 is provided between the semiconductor cooling chip 8 and the inner wall of the cooling box 1. The upper and lower outer walls of the sealing rubber gasket 10 are tightly fitted to the semiconductor cooling chip 8 and the cooling box 1, which plays a sealing role, preventing cold air leakage in the cooling box 1, and also reducing the transfer of external heat.

[0025] Four support feet are welded and fixed to the bottom outer wall of the cooling box 1. The support feet are made of stainless steel, which can stably support the cooling box 1 on the ground, avoid the bottom of the cooling box 1 from directly contacting the ground, and reduce the impact of ground moisture on the equipment.

[0026] The implementation principle of the soil pyrolysis gas cooling treatment device in this application embodiment is as follows: When the device is working, the soil pyrolysis gas enters the filter cylinder 2 from the air inlet 201. The pyrolysis gas comes into contact with the interception cylinder 3 inside the filter cylinder 2. The impurities in the pyrolysis gas are intercepted by the interception cylinder 3. The filtered pyrolysis gas enters the cooling pipe 6 from the exhaust port 202.

[0027] The semiconductor cooling chip 8 is activated, and its cooling surface cools the coolant in the cooling box 1. The coolant in the cooling box 1 exchanges heat with the cooling pipe 6, cooling the pyrolysis gas in the cooling pipe 6. The heat generated by the semiconductor cooling chip 8 is dissipated through the heat-conducting fins 9. At the same time, the cooling fan 11 is activated, and the cooling fan 11 causes air to convect between the heat-conducting fins 9, accelerating heat dissipation and improving cooling efficiency. The cooled pyrolysis gas is discharged from the other end of the cooling pipe 6 for subsequent processing.

[0028] When it is necessary to clean the interceptor cylinder 3, open the mounting top plate 4, remove the interceptor cylinder 3 through the connecting bracket 5, clean it, and then reinstall it back into the filter cylinder 2.
