[0002] When treating dioxins produced by combustion or industry, the exhaust gas is first introduced into a condenser for condensation. The condensed exhaust gas is then introduced through an air duct into an adsorption column filled with adsorption fillers for adsorption treatment. Therefore, there is a large temperature difference between the inside and outside of the air duct. Long-term operation can easily cause the air duct to burst, leading to exhaust gas leakage, posing a safety hazard. Summary of the invention

[0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the utility model provides a temperature-regulating gas-guiding connection structure for dioxin condensation treatment. By adding a pipe sleeve to the gas pipe, a temperature-regulating cavity is formed between the two to allow the temperature-regulating medium to pass through, thereby reducing the temperature difference between the inside and outside of the gas pipe and preventing the gas pipe from bursting due to excessive temperature difference between the inside and outside.

[0005] The air duct is wrapped with a pipe sleeve on the outside, and a temperature regulating cavity is formed between the air duct and the pipe sleeve. A temperature regulating medium is introduced into the temperature regulating cavity. Through heat exchange between the temperature regulating medium and the air duct, the temperature difference between the external temperature regulating medium environment and the internal exhaust gas environment of the air duct is reduced.

[0006] Furthermore, it includes a temperature control medium supply source; the pipe sleeve has a medium inlet and a medium outlet located at both ends, and the temperature control medium supply source supplies the temperature control medium to the temperature control clamp cavity through an input pipeline connected to the medium inlet, so that the temperature control medium is in a flow state in and out of the temperature control clamp cavity.

[0007] Furthermore, the interface between the air guide pipe, the condenser and the adsorption column is respectively installed with a first temperature sensor and a second temperature sensor through a three-way pipe.

[0008] Furthermore, a third temperature sensor for detecting the temperature of the temperature regulating medium in the temperature regulating clamp cavity is arranged on the pipe sleeve.

[0009] Furthermore, the pipe sleeve is composed of a pair of pipe half shells connected by flanges, and a sealing gasket is provided at the flange connection; a ring plug fixed on the air guide pipe is provided at the pipe opening position corresponding to the pipe sleeve, and the ring plug is squeezed when the pair of pipe half shells are spliced ​​and installed to seal the port of the temperature regulating clamp cavity and support the pipe sleeve through the ring plug.

[0010] Furthermore, the pipe sleeve is made of thermal insulation material.

[0011] Furthermore, the temperature control medium is a gaseous medium or a liquid medium.

[0012] Furthermore, the air guide tube has an arched structure.

[0013] Beneficial effect: The utility model adds a pipe sleeve to the air duct to form a temperature regulating cavity between the two to allow the temperature regulating medium to pass through. The temperature regulating medium is a gaseous medium or a liquid medium, thereby reducing the temperature difference between the inside and outside of the air duct, avoiding the air duct from bursting due to excessive temperature difference between the inside and outside, and improving safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Attached Figure 1 It is a schematic diagram of the overall structure of the utility model;

[0015] Attached Figure 2 Schematic diagram of the structure of the airway tube and the tube sleeve. DETAILED DESCRIPTION

[0016] The utility model is further described below in conjunction with the accompanying drawings.

[0017] As attached Figure 1 and attached Figure 2 As shown, the temperature-regulating air-guiding connection structure for dioxin condensation treatment includes an air-guiding pipe 3 connected between the condenser 1 and the adsorption column 2. The exhaust gas condensed by the condenser 1 is introduced into the adsorption column 2 through the air-guiding pipe 3. The adsorption column 2 is filled with an adsorption filler 20. Due to the large temperature difference between the inside and outside of the air-guiding pipe 3, the air-guiding pipe 3 may easily burst during long-term operation, resulting in exhaust gas leakage, posing a safety hazard.

[0018] In order to solve the above problems, the solution proposed by the utility model is as follows: the air duct 3 is wrapped with a pipe sleeve 4, and a temperature-adjusting cavity 34 is formed between the air duct 3 and the pipe sleeve 4. A temperature-adjusting medium is introduced into the temperature-adjusting cavity 34, and the temperature difference between the external temperature-adjusting medium environment and the internal exhaust gas environment of the air duct 3 is reduced through heat exchange between the temperature-adjusting medium and the air duct 3. The utility model adds a pipe sleeve 4 to the air duct 3 to form a temperature-adjusting cavity 34 between the two into which a temperature-adjusting medium can be introduced. The temperature-adjusting medium is a gaseous medium or a liquid medium, thereby reducing the temperature difference between the inside and outside of the air duct 3, avoiding the air duct 3 from bursting due to excessive temperature difference between the inside and outside, and improving safety.

[0019] The utility model includes a temperature control medium supply source 9; the pipe sleeve 4 has a medium inlet 4a and a medium outlet 4b located at both ends. The temperature control medium supply source 9 supplies the temperature control medium to the temperature control clamping cavity 34 through an input pipeline connected to the medium inlet 4a, so that the temperature control medium is in a flow state in and out of the temperature control clamping cavity 34. The temperature control effect of the temperature control medium in the flow state is better.

[0020] Among them, if the temperature control medium is a gaseous medium, such as air, the temperature control medium supply source 9 should be a gas supply device that can adjust the gas temperature; if the temperature control medium is a liquid medium, such as water, the temperature control medium supply source 9 should be a water supply device that can adjust the water temperature.

[0021] The interface between the air duct 3 and the condenser 1 and the adsorption column 2 is respectively installed with a first temperature sensor 6 and a second temperature sensor 7 through a three-way pipe 5. Relative to the air duct 3, the first temperature sensor 6 is used to detect the temperature of the input exhaust gas, and the second temperature sensor 7 is used to detect the temperature of the output exhaust gas, and there is a temperature difference between the two. If the detection value of the first temperature sensor 6 (that is, the temperature value of the exhaust gas at the input air duct 3) is a, the detection value of the second temperature sensor 7 (that is, the temperature value of the exhaust gas at the output of the air duct 3) is b, and the required temperature value of the temperature control medium is c, then it satisfies: c = (a + b) / 2, that is, the temperature of the temperature control medium selects the average value of the exhaust gas temperature at the input end and the output end of the air duct 3, so that the temperature difference between the inside and outside of the air duct 3 is in a smaller range, providing a suitable temperature control environment.

[0022] More specifically, the pipe sleeve 4 is provided with a third temperature sensor 8 for detecting the temperature of the temperature regulating medium in the temperature regulating clamping cavity 34 .

[0023] As attached Figure 2 As shown, the pipe sleeve 4 is composed of a pair of pipe half shells 41 connected by flanges, and a sealing gasket 10 is provided at the flange connection; a ring plug 11 fixed on the air guide pipe 3 is provided at the pipe opening position corresponding to the pipe sleeve 4, and the ring plug 11 is squeezed when the pair of pipe half shells 41 are spliced ​​and installed, so as to seal the port of the temperature regulating clamping cavity 34 and support the pipe sleeve 4 through the ring plug 11, thereby improving the assembly convenience of the pipe sleeve 4, and ensuring the sealing of the temperature regulating clamping cavity 34, and avoiding leakage of the temperature regulating medium.

[0024] In order to better insulate the temperature control medium, the pipe sleeve 4 is made of a heat-insulating material.

[0025] In the present invention, the air guide pipe 3 is of an arched structure, which can reduce the resistance of exhaust gas diversion, and the pipe sleeve 4 is also adaptively designed to be an arched shape, which can also reduce the resistance of temperature control medium diversion.

[0026] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
