Description

Technical Field

[0001] This utility model relates to the technical field of waste gas treatment equipment, specifically to a pipeline structure for cooling waste gas treatment equipment. Background Technology

[0002] The cooling pipeline structure of the waste gas treatment equipment is a "bridge" connecting the high-temperature waste gas source and the subsequent treatment system. Its core function is to achieve precise control of the waste gas temperature through reasonable pipeline design and medium regulation, which not only ensures the safe and stable operation of the treatment equipment, but also improves purification efficiency, reduces energy consumption, and meets environmental protection standards.

[0003] In existing waste gas treatment equipment, the incoming waste gas is cooled by heat exchange through pipelines. In some existing waste gas cooling pipelines, the outer pipe and the inner heat exchange pipe are often fixed together. Although this method has high sealing performance and good heat exchange effect, the service life of the inner gas pipe is easily reduced due to temperature difference changes. As a result, the inner pipe is more prone to damage than the outer pipe. Once damaged, it is inconvenient for personnel to disassemble and replace the inner pipe, so there are still some shortcomings.

[0004] In conclusion, it is necessary to invent a pipeline structure for cooling waste gas treatment equipment. Utility Model Content

Detailed Implementation

[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0023] See attached document Figures 1-5 This utility model provides a pipeline structure for cooling waste gas treatment equipment, including a heat dissipation outer pipe 100 and a heat exchange pipe 400. The heat dissipation outer pipe 100 has a two-section structure, and the heat dissipation outer pipe 100 can be sleeved on the outside of the heat exchange pipe 400 by a butt joint, so that a heat exchange space can be left between the heat dissipation outer pipe 100 and the heat exchange pipe 400. The heat exchange pipe 400 is set inside the heat dissipation outer pipe 100. Both ends of the outer wall of the heat exchange pipe 400 are provided with air inlet pipes 110 for conveying waste gas. The opposite end of the air inlet pipe 110 is fixedly connected to both ends of the heat exchange pipe 400 by flange 120. The air inlet pipe 110 is provided to convey the waste gas to be cooled into the heat exchange pipe 400. Both ends of the heat dissipation outer pipe 100 are provided with rubber seals between them and the outer walls of the heat exchange pipe 400 to improve the sealing effect after the heat dissipation outer pipe 100 is closed.

[0024] A cooling mechanism for cooling exhaust gas is provided between the heat dissipation outer tube 100 and the heat exchange tube 400. The cooling mechanism includes a liquid inlet pipe 200, which is located on the upper and lower sides of the outer wall of the heat dissipation outer tube 100. The other end of the liquid inlet pipe 200 can be connected to the water pump of a chiller (existing technology, not shown in the figure). The low-temperature water to be cooled can be transported to the storage tank 210 through the liquid inlet pipe 200. The inner wall of the heat dissipation outer tube 100 is provided with a storage tank 210 for storing the cooled water. A water inlet seat is fixedly connected to the outer wall of the heat dissipation outer tube 100 at a position corresponding to the storage tank 210. The bottom end of the water inlet seat is connected to the inner wall of the liquid storage tank 210, and the liquid inlet pipe 200 is detachably fixed to the water inlet seat. Both ends of the liquid inlet pipe 200 are fixedly connected to the water inlet seat. The inner wall of the heat dissipation outer pipe 100 and the corresponding position of the liquid storage tank 210 are fixedly connected to the atomizing nozzles 220. Multiple atomizing nozzles 220 are evenly arranged in an array. The low temperature water entering the liquid storage tank 210 can be sprayed onto the heat exchange tube 400 through the atomizing nozzles 220, so that the heat exchange tube 400 can exchange heat between the exhaust gas and the low temperature water through the heat dissipation fins 130.

[0025] The outer wall of the heat exchange tube 400 is fixed with heat dissipation fins 130 to improve heat exchange. Multiple heat dissipation fins 130 are evenly arranged in a ring array. The heat dissipation fins 130 mainly increase the heat exchange area of ​​the heat exchange tube 400, thereby improving the heat exchange and cooling effect. Baffles 140 are provided on the upper and lower sides of the inner wall of the heat exchange tube 400. Multiple baffles 140 are arranged in a staggered manner. The length of the baffles 140 is greater than half the diameter of the heat exchange tube 400. The baffles 140 are designed to reduce the flow of flue gas through the heat exchange tube 400. The heat exchange rate is increased to improve the heat exchange and cooling effect of the heat exchange tube 400. Fixing rings 300 are provided on both sides of the outer wall of the heat dissipation outer tube 100. Connecting plates 310 are fixed at both ends of the fixing rings 300. The connecting plates 310 are fixedly connected by bolts. A drain pipe 320 is also connected to one side of the bottom of the inner wall of the heat dissipation outer tube 100. The fixing rings 300 are two-section structures. They can be pressed and fixed to the heat dissipation outer tube 100 by bolts and connecting plates 310. The drain pipe 320 is used to drain the cooling water after heat exchange.

[0026] The usage process of this utility model is as follows: Those skilled in the art can first assemble the device according to the above description, then connect all electrical equipment to an external power supply, and control the operation of the device through an external controller. The control programs of all electrical equipment are edited by the production personnel in advance before production. This utility model does not make any technical improvements here, but only assumes that it can normally meet the needs of personnel.

[0027] The inlet pipe 110 can transport exhaust gas to the heat exchange pipe 400, and the heat exchange pipe 400 can reduce the rate of flue gas passage through the baffle 140. At the same time, the chiller can transport cooling water to the storage tank 210 through the liquid inlet pipe 200. The storage tank 210 can spray the cooling water onto the heat exchange pipe 400 and the heat dissipation fins 130 through the atomizing nozzle 220. The heat exchange pipe 400 can allow the exhaust gas and cooling water to exchange heat and cool down through the heat dissipation fins 130. The cooled exhaust gas can be discharged through the heat dissipation outer pipe 100 on the other side, and the cooling water can be discharged through the drain pipe 320.

[0028] When the heat exchange tube 400 has been in use for a long time, personnel can unscrew the flange 120 to separate the heat dissipation outer tube 100 and the heat exchange tube 400 from the air inlet pipe 110. Then, the bolts on the fixed connection plate 310 can be loosened to remove the fixing ring 300. After that, personnel can separate the heat dissipation outer tube 100 from the top and bottom, so that the heat exchange tube 400 can be inspected and repaired.

[0029] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model are within the scope of protection claimed by this utility model.
