[0032] Figure 2This is a structural schematic diagram of a pipeline structure for cooling an exhaust gas treatment device according to an embodiment of the utility model. The pipeline structure for cooling an exhaust gas treatment device provided in this embodiment includes a first water inlet module 100, a first pipe 200 and a nozzle 300. The first water inlet module 100 is used to receive and transmit coolant. The first pipe 200 is arranged downstream of the first water inlet module 100, and is used to receive the coolant transmitted by the first water inlet module 100. An external thread 210 is provided at one end of the first pipe 200, and a fastening connection is achieved by screwing the external thread 210 into the first water inlet module 100. The other end of the first pipe 200 is connected to the nozzle 300, and the nozzle 300 is used to spray coolant to cool the exhaust gas treatment device, wherein the root of the external thread 210 smoothly transitions to the outer surface of the first pipe.
[0033] In the above embodiment, a smooth transition is provided between the root of the external thread 210 and the outer surface of the first pipe, which can reduce the stress concentration at the root of the external thread 210 on the first pipe 200, improve the overall strength of the threaded connection, and improve the bearing capacity of the first pipe 200. At the same time, the smooth transition can reduce the risk of wear, further improve the fatigue life and reliability of the first pipe 200, and avoid the generation of fatigue and cracks at the external thread 210 of the first pipe 200, thereby avoiding the phenomenon of water leakage or even breakage of the coolant pipeline during the operation of the exhaust gas treatment equipment.
[0034] In the above embodiments, circulating water may be used as the coolant. In other embodiments, other liquids with cooling capabilities may also be used, which is not specifically limited here.
[0035] In some embodiments, in the pipeline structure for cooling exhaust gas treatment equipment provided in this embodiment, the thread root of the external thread 210 on the first pipe 200 smoothly transitions with the outer surface of the first pipe 200 to form a transition section 220, and the included angle between the generatrix of the transition section 220 and the generatrix of the external thread 210 is an obtuse angle.
[0036] In the above embodiment, the included angle between the generatrix of the transition section 220 and the generatrix of the external thread 210 is set to be an obtuse angle, which reduces the stress concentration at the root of the external thread 210, improves the overall connection strength, and avoids leakage or even breakage in the coolant pipeline. It should be noted that in other embodiments, the transition section 220 can also be a smooth transition, which is not specifically limited here.
[0037] See also Figure 1 In the second pipe 10 of the prior art, the root of the thread on the second pipe 10 is designed at a right angle to the outer surface of the second pipe 10, and the stress is concentrated on the root of the thread on the second pipe 10, which is prone to breakage.
[0038] In some embodiments, the included angle between the busbar of the transition section 220 and the busbar of the external thread 210 is 156.8°. When the included angle between the busbar of the transition section 220 and the busbar of the external thread 210 is designed to be 156.8°, the root of the external thread 210 of the first pipe 200 has an optimal load-bearing capacity, which can greatly improve the root connection strength of the external thread 210, and avoid the phenomenon of coolant pipeline breakage during the operation of the exhaust gas treatment equipment to a great extent.
[0039] In some embodiments, in the pipeline structure for cooling the exhaust gas treatment equipment provided in this embodiment, the first water inlet module 100 includes a hand valve 110, a stainless steel pipe 120 and a blind plate opening flange 140. The hand valve 110 is provided with a water inlet for receiving the coolant. The hand valve 110 can adjust the flow rate of the coolant. The stainless steel pipe 120 is arranged downstream of the hand valve 110 for transmitting the coolant. The blind plate opening flange 140 is arranged downstream of the stainless steel pipe 120 for connecting the stainless steel pipe 120 with the first pipe 200. A second threaded hole is provided on the blind plate opening flange 140. The external thread 210 of the first pipe 200 can be screwed into the second threaded hole to achieve a tight connection.
[0040] In the above embodiment, the manual valve 110 is disposed at the most upstream of the entire pipeline structure, so as to adjust the coolant flow of the entire pipeline structure.
[0041] In some embodiments, in the pipeline structure for cooling the exhaust gas treatment equipment provided in this embodiment, the first water inlet module 100 further includes a stainless steel right-angle joint 130, which is arranged upstream of the blind plate opening flange 140 to change the transmission direction of the coolant. In the transmission loop of the coolant, if the direction needs to be changed, the stainless steel right-angle joint 130 can be used.
[0042] In some embodiments, the hand valve and the stainless steel pipe are connected by a ferrule medium group. Compared with other pipe connection components, the ferrule medium group has the advantages of reliable sealing performance, easy installation and disassembly, diverse material selection, and applicability to various pipe materials and sizes.
[0043] In some embodiments, the first pipeline 200 includes a polytetrafluoroethylene tube. Polytetrafluoroethylene has excellent corrosion resistance, high temperature resistance, low friction coefficient, non-stickiness and other characteristics, and has extremely high chemical stability. It can withstand corrosion from a variety of strong acids, strong alkalis, organic solvents and oxidants. Using a polytetrafluoroethylene tube as the first pipeline 200 can improve the stability and service life of the pipeline structure.
[0044] In some other embodiments, the first pipe 200 may be made of other materials, such as polyethylene, polyimide, etc., which are not specifically limited here.
[0045] In some embodiments, in the pipeline structure for cooling the exhaust gas treatment equipment provided in this embodiment, the nozzle 300 includes a spiral nozzle. Compared with ordinary nozzles, the spiral nozzle is not easy to be clogged. The spiral nozzle can form a conical spray surface. Compared with ordinary nozzles, it can provide a more uniform and wider coverage. The spiral nozzle realizes dripping mist liquefaction through the spiral structure of the nozzle itself, provides a fine and uniform atomization effect, and the spray is smooth.
[0046] In some embodiments, in the pipeline structure for cooling the exhaust gas treatment equipment provided in this embodiment, a first threaded hole is provided at the other end of the first pipe 200, and the nozzle 300 can be screwed into the first threaded hole to achieve a fastened connection. The nozzle 300 and the first pipe 200 are fastened and connected by threaded connection, which is simple to operate, convenient to disassemble and maintain, and compared with the connection method through an adapter 20 in the prior art, one threaded assembly is reduced, and the original price cost and labor cost are reduced, which ensures that the original function remains unchanged and greatly improves the reliability of the product.
[0047] The present embodiment also provides an exhaust gas treatment device, comprising a pipeline structure for cooling the exhaust gas treatment device according to any of the above embodiments, wherein an external thread 210 is provided at one end of the first pipe 200 for screwing into the first water inlet module 100 to achieve a tightening connection, and the root of the external thread 210 smoothly transitions to the outer surface of the first pipe 200, thereby reducing stress concentration at the root of the external thread 210, improving the bearing capacity, and reducing the risk of wear, thereby improving the fatigue life and reliability of the first pipe 200, avoiding the generation of fatigue or cracks at the external thread 210 of the first pipe 200, thereby avoiding the phenomenon of water leakage or even breakage of the coolant pipeline during the operation of the exhaust gas treatment equipment.
