[0003] In the Chinese patent with the publication number CN221802575U, a waste gas purification device with waste heat recovery is mentioned, which can fully absorb the heat in the waste gas through the waste heat recovery component, so that the waste heat can be utilized in other places. The cleaning component can prevent equipment from accumulating dust, and the gas detector can detect the degree of waste gas purification. If the waste gas purification is not up to standard, the medicine tank can add medicine to the purification reaction tank.

[0004] Although the above-mentioned device can absorb the heat in the waste gas through the waste heat recovery component, but during use, since the waste gas is only injected into the gas inlet pipeline and then conducted through the heat exchange pipeline surrounding the pipeline, the contact area between the heat exchange pipeline and the gas inlet pipeline is limited, thereby limiting the waste heat recovery efficiency. UTILITY MODEL CONTENTS

[0005] The utility model aims at providing a waste gas purification device of waste heat recovery to solve the problems in the prior art.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0013] Compared with the prior art, the present application has the advantages that:

[0014] Firstly, the present application is characterized in that the air inlet mechanism, the waste heat recovery mechanism, the heat conduction mechanism and the valve plate mechanism are cooperated with each other, so that the efficiency of waste heat recovery is improved. When the exhaust gas enters from the bottom of the air inlet box, the exhaust gas passes through the heat conduction frame, the partition plate one, the partition plate two and the adapter blocks. These components not only effectively conduct heat to the heat conduction pipe, but also the whole heat conduction mechanism penetrates the adapter blocks, so that the heat in the exhaust gas is further recovered. In this way, the contact area of the exhaust gas and each component is increased, so that the efficiency of waste heat recovery is greatly improved.

[0015] Secondly, the present application is characterized in that the air inlet mechanism, the waste heat recovery mechanism, the heat conduction mechanism and the valve plate mechanism are cooperated with each other, so that the heat recovery process is further optimized. When the flue gas enters the air inlet mechanism and causes the internal temperature to rise, the temperature sensor will immediately monitor this change and feed back the information to the external control device. Then, the control device will instruct the hydraulic cylinder to start, so that the valve plate as a whole moves downward and closes the exhaust port. This action can ensure that the exhaust gas accumulates in the air inlet mechanism, so that the contact time of the exhaust gas with the waste heat recovery mechanism and the heat conduction mechanism is prolonged. The heat in the exhaust gas can be more fully absorbed, and the waste of heat is effectively avoided. BRIEF DESCRIPTION OF DRAWINGS

[0032] The valve plate mechanism 5 includes a valve plate 51 and a temperature sensor 52 mounted on the bottom of the valve plate 51. The valve plate mechanism 5 is used to close the exhaust port 22 to increase the residence time of exhaust gas inside the intake mechanism 2.

[0033] In a further embodiment, an exhaust port 22 is provided above the air intake box 21, and an air intake port 23 is provided below the air intake box 21. The exhaust port 22 is inserted into the bottom of the purification cylinder 1, and the heat conduction frame 31 is installed inside the air intake box 21.

[0034] In this embodiment, the bottom end of the valve plate 51 is fitted with the port of the exhaust port 22. When the valve plate 51 is raised, a gap will be created, allowing the exhaust gas to enter the purification cylinder 1.

[0035] In a further embodiment, partition 1 32 and partition 2 33 are evenly distributed on the inner side of heat-conducting frame 31, and one end of partition 1 32 and partition 2 33 are fixedly connected to heat-conducting frame 31. Connecting block 34 is distributed between partition 1 32 and partition 2 33, and the connecting block 34 is penetrated by heat-conducting mechanism 4.

[0036] In this embodiment, the heat-conducting tube 35 passes through the space between each heat-conducting mechanism 4.

[0037] In a further embodiment, the heat-conducting tube 35 passes through the heat-conducting frame 31 and the air inlet box 21. The heat-conducting tube 35 is evenly arranged and inserted on one side of the partition 1 32 and the partition 2 33. The heat-conducting mechanism 4 is composed of an inlet straight tube 41, a bend 1 43, a bend 2 44 and an outlet straight tube 42 connected to each other. The partition 1 32 is located on one side of the bend 2 44 and the partition 2 33 is located on one side of the bend 1 43.

[0038] In this embodiment, the inlet straight pipe 41 is an air inlet pipe, and the outlet straight pipe 42 is an air outlet pipe, thereby transporting the heat-conducting medium to conduct heat and absorb waste heat.

[0039] In a further embodiment, sliding blocks 53 are fixedly connected to both sides of the valve plate 51, and the sliding blocks 53 are slidably connected to the inner side of the purification cylinder 1. Hydraulic cylinders 54 are installed on both sides of the purification cylinder 1, and the output end of the hydraulic cylinder 54 is connected to the sliding blocks 53.

[0040] In this embodiment, the purification cylinder 1 has a sliding groove box at the sliding block 53, and the hydraulic cylinder 54 is installed above the sliding groove box. The output end of the hydraulic cylinder 54 is provided with a seal so as to control the up and down movement of the valve plate 51.

[0041] In a further embodiment, a notch 55 is provided on one side of the valve plate 51 for the passage of exhaust gas.

[0042] In this embodiment, the purification cylinder 1 is the cylinder used in the prior art for exhaust gas purification equipment. It is equipped with a purification filter screen inside, and there is a dispersion plate above the valve plate 51 to distribute the exhaust gas evenly before purification.

[0043] The working principle of this utility model is as follows:

[0044] When external exhaust gas enters the interior of the intake box 21 through the intake port 23 at the bottom of the intake box 21, it passes through the interior of the heat-conducting frame 31 and the periphery of the partition 1 32, partition 2 33 and connecting block 34, thereby conducting heat to the partition 1 32 and partition 2 33, and then conducting heat to the heat-conducting tube 35 inserted on one side of the partition 1 32 and partition 2 33, thereby recovering part of the heat. In addition, since the heat-conducting mechanism 4 runs through all the connecting blocks 34, when the exhaust gas passes around the partition 1 32 and partition 2 33, some of the heat will also be conducted from the connecting blocks 34 to the heat-conducting mechanism 4, thereby transferring another part of the heat to the heat-conducting mechanism 4, and then the heat-conducting mechanism 4 will recover this part of the heat. This can increase the contact surface between the exhaust gas and the heat-conducting frame 31, partition 1 32, partition 2 33, connecting block 34, heat-conducting tube 35 and heat-conducting mechanism 4, thereby improving the waste heat recovery efficiency.

[0045] When the flue gas enters the interior of the intake mechanism 2 and causes its internal temperature to rise, the temperature sensor 52 monitors and feeds back to the external control device, thereby causing the hydraulic cylinder 54 to operate. This causes the valve plate 51 to move down as a whole, closing the exhaust port 22. This allows the exhaust gas to accumulate inside the intake mechanism 2, thereby prolonging the contact time between the exhaust gas and the waste heat recovery mechanism 3 and the heat conduction mechanism 4, thus enabling more comprehensive heat absorption and avoiding waste.

[0046] When the temperature monitored by the temperature sensor 52 is lower than the set temperature, the hydraulic cylinder 54 can be activated, allowing the exhaust gas in the intake mechanism 2 to pass through the opening 55 and enter the interior of the purification cylinder 1 for purification.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
