[0031] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are intended only to illustrate the relevant utility model and are not intended to limit the scope of the utility model. It should also be noted that, for ease of description, only the portions relevant to the utility model are shown in the accompanying drawings.

[0032] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0033] Please refer to Figures 1 to 6 The embodiment of the present invention provides an efficient and energy-saving organic waste gas treatment device including an incinerator body 11, an air inlet pipe 13 and an air outlet pipe 14 are arranged below the incinerator body 11 along a first direction. The first direction is Figure 1 In the front-back direction, a support frame 12 is provided at the bottom of the incinerator body 11, and the air inlet pipe 13 and the air outlet pipe 14 are both provided inside the support frame 12. The axis extension direction of the air inlet pipe 13 and the air outlet pipe 14 is the second direction. The second direction is Figure 1 In the left and right directions, the air inlet pipe 13 has an air inlet end connected to the fan, and the air outlet pipe 14 has an air outlet end connected to the extension chimney 15. The organic waste gas treatment equipment also includes a waste heat utilization mechanism 2, which includes:

[0034] The preheating pipe section 21 is detachably mounted on the air inlet end;

[0035] The recovery pipe section 22 is detachably mounted at the air outlet end;

[0036] Two heat exchange sections are respectively provided on the preheating tube segment 21 and the recovery tube segment 22, including an upper box 24 provided at the top of the preheating tube segment 21 and the recovery tube segment 22, and a lower box 23 provided at the bottom of both. A plurality of heat exchange groups are provided between the upper box 24 and the corresponding lower box 23. Each heat exchange group includes a plurality of heat exchange tubes 25 uniformly arranged along a first direction. The heat exchange tubes 25 of adjacent heat exchange groups are staggered. Each heat exchange tube 25 is provided with fins 26 at both ends along the second direction. Each upper box 24, each lower box 23 and each heat exchange tube 25 is filled with a heat exchange solution. The first direction and the second direction are perpendicular to each other.

[0037] The driving assembly 3 is provided between the recovery pipe section 22 and the extension chimney 15 and is used to drive the heat exchange solution to circulate between the two heat exchange parts;

[0038] like Figure 1 、 Figure 2 and Figure 5 As shown, the top of each heat exchange tube 25 is connected to the corresponding upper box 24, and the bottom end is connected to the corresponding lower box 23. The driving component 3 drives the heat exchange solution from the upper box 24 of the recovery tube segment 22 to the upper box 24 of the preheating tube segment 21, flows along each heat exchange tube 25 into the lower box 23 of the preheating tube segment 21, and then flows to the lower box 23 of the recovery tube segment 22, and finally flows back to the interior of the upper box 24 of the recovery tube segment 22 through each heat exchange tube 25, realizing the circulation of the heat exchange solution. The heat exchange tube 25 inside the recovery tube segment 22 will contact the purified exhaust gas for heat exchange. The heat exchange solution absorbs the heat of the purified exhaust gas and then flows through the heat exchange tube 25 inside the preheating tube segment 21. The heat exchange solution transfers the heat to the untreated exhaust gas. The waste gas to be processed is preheated. On this basis, the heat exchange tubes 25 of adjacent heat exchange groups are arranged in a staggered manner. Each heat exchange tube 25 is provided with fins 26 at both ends along the second direction. The contact area with the waste gas is larger, which improves the heat exchange efficiency. Furthermore, after the heat exchange solution is heated, it flows to the heat exchange part of the preheating pipe segment 21 to preheat the waste waiting for treatment. Compared with the water-conducting hose installed on the outside of the air inlet main pipe 13, the heat exchange tube 25 is set on the necessary path of the waste gas flow, which fully ensures the heat exchange efficiency and solves the problem of low waste heat utilization efficiency in the prior art. The pipe segment can be replaced for maintenance, which is more convenient to use and more practical. Optionally, the heat exchange solution is water, or a mixed solution of water and ethylene glycol solution.

Figure 1 In the vertical direction, the ends of the two clamping plates 29 that are away from each other abut against the bottom surface of the upper box body 24 and the top surface of the lower box body 23 respectively. A clamping groove 210 is provided at the position of each clamping plate 29 corresponding to the fin 26. The first direction, the second direction and the third direction are perpendicular to each other.

[0040] like Figure 3 、 Figure 4 and Figure 5 As shown, since the exhaust gas still contains a small amount of debris and dust, after being filtered through the dustproof net 28, the debris and dust are reduced from entering the incinerator body 11, thereby avoiding the situation where the exhaust gas treatment efficiency is reduced due to the debris and dust; in addition, the ends of the two clamping plates 29 that are away from each other respectively abut the bottom surface of the upper box body 24 and the top surface of the lower box body 23, thereby realizing the preliminary installation of the retaining ring 27, and further clamping the slot 210 on the outer side of the corresponding fin 26 to realize the further installation of the retaining ring 27, thereby ensuring the stability of the retaining ring 27 after installation; preferably, the clamping plate 29 is arranged at the end of the heat exchange part away from the air inlet main pipe 13, so that the retaining ring 27 can better maintain stability when impacted by the exhaust gas.

[0041] In some embodiments, the drive assembly 3 includes:

[0042] The driving pipe section 31 is detachably mounted between the recovery pipe section 22 and the extension chimney 15;

[0043] The drive unit includes a drive shaft 33 that passes through the drive pipe section 31. A drive blade 34 is provided in the middle of the drive shaft 33.

[0044] The connection part includes a return pipe 211 connecting the two lower boxes 23, a liquid inlet pipe 37 connecting one upper box 24 and the pump housing 35, and a liquid delivery pipe 38 connecting the other upper box 24 and the pump housing 35;

[0045] like Figure 5 and Figure 6 As shown, the pump casing 35 and the centrifugal impeller 36 are combined to form a centrifugal pump body, and the airflow of the exhaust gas discharge will push the driving blades 34, and then drive the driving shaft 33 to drive the centrifugal impeller 36 to rotate, thereby achieving the purpose of driving the heat exchange solution to circulate, and the heat exchange solution inside an upper box body 24 is extracted through the liquid inlet pipe 37, and then the heat exchange solution is loosened into the other upper box body 24 through the liquid delivery pipe 38. Furthermore, the heat exchange solution flows between the two lower boxes 23 through the return pipe 211, thereby achieving the purpose of driving the heat exchange solution to circulate. Optionally, short connecting pipes are provided on the upper box body 24, the lower box body 23 and the pump casing 35, and the return pipe 211, the liquid delivery pipe 38 and the liquid inlet pipe 37 are all connected to the short connecting pipe through flanges. The return pipe 211, the liquid delivery pipe 38 and the liquid inlet pipe 37 are detachable through the flange connection, which facilitates the inspection and replacement of the three.

[0046] In some embodiments, a tapered passage 32 is provided inside the driving pipe segment 31. The tapered passage 32 has a first opening near the end of the recovery pipe segment 22 and a second opening near the end of the extension chimney 15. The inner diameter of the first opening is larger than the inner diameter of the second opening.

[0047] like Figure 5 As shown, according to Bernoulli's principle, when a quantitative fluid passes through an opening with a small cross-sectional area, its flow rate will increase. Therefore, the exhaust gas is guided to flow from the first opening to the second opening, so that the exhaust gas flow rate is accelerated, which makes it easier to drive the drive blades 34 and the drive shaft 33 to rotate, thereby increasing the flow rate of the heat exchange solution and ensuring the preheating effect.

[0048] In some embodiments, the axis of the drive shaft 33 extends in a third direction, a sealing shaft seat 310 is embedded in the wall of the drive pipe section 31, the bottom end of the drive shaft 33 is disposed in the sealing shaft seat 310, a support block 39 is disposed on the outer wall of the drive pipe section 31, and the pump housing 35 is mounted on the top surface of the support block 39;

[0049] like Figure 6 As shown, the support block 39 is used to improve the stability of the installation of the pump housing 35, and the sealing shaft seat 310 is used to improve the rotation stability of the drive shaft 33, thereby ensuring the stable rotation of the centrifugal impeller 36 and stably driving the flow of the heat exchange solution in the pump housing 35, thereby improving the stability of the drive component 3 during operation.

[0050] In some embodiments, the air inlet end of the air inlet main pipe 13 is detachably connected to the preheating pipe segment 21 via a flange, and both ends of the recovery pipe segment 22 are detachably connected to the air outlet end of the air outlet main pipe 14 and the drive pipe segment 31 via flanges, respectively. The end of the drive pipe segment 31 away from the recovery pipe segment 22 is detachably connected to the extension chimney 15 via a flange.

[0051] like Figure 2 and Figure 5 As shown, the exhaust gas passes through the preheating pipe segment 21, the air inlet pipe 13, the incinerator body 11, the air outlet pipe 14, the recovery pipe segment 22 and the drive pipe segment 31 in sequence, and finally flows into the extension chimney 15 and is discharged. The flange connection makes disassembly and assembly more convenient, and disassembly, assembly, replacement and maintenance are more convenient, which improves the practicality of the equipment and the convenience of operation. Optionally, the preheating pipe segment 21, the recovery pipe segment 22 and the drive pipe segment 31 are combined into a set, and multiple ones can be installed through flanges to increase the preheating effect and waste heat recovery effect, facilitate operation, and achieve better waste heat utilization effect.

[0052] In some embodiments, a liquid injection valve is provided at the top of the middle portion of the liquid inlet pipe 37;

[0053] like Figure 2 and Figure 6As shown, the liquid inlet pipe 37 is the highest point in the flow path of the heat exchange solution. The liquid injection valve set here can fill all the upper boxes 24, all the lower boxes 23 and all the heat exchange tubes 25 with heat exchange solution, reduce gas residue, and ensure that the centrifugal impeller 36 can stably extract the heat exchange solution in the upper box 24.
