Description

Technical Field

[0001] The utility model relates to the technical field of boilers, in particular to a heat-insulating serpentine pipe for a biomass processing boiler. Background Art

[0002] A boiler is an energy conversion device. The energy input into the boiler includes the chemical energy in fuel and electric energy. The boiler outputs steam, high-temperature water or organic heat carriers with a certain amount of heat energy. The original meaning of "pot" refers to a water container heated on fire, and "furnace" refers to a place for burning fuel. A boiler includes two major parts: the pot and the furnace. Tubes that wind circuitously multiple times in a plane, the convective heating surface of the boiler, such as economizers, superheaters and reheaters, etc., usually adopt the structure of serpentine pipes, and there are two layout methods: horizontal and vertical. The vertical serpentine pipes are prone to water accumulation in the pipes after the boiler stops running, but are convenient for supporting and hanging. There is an existing patent, patent publication number CN108007018B, a serpentine tube microchannel heat exchanger, which includes: two header pipes and a plurality of flat tubes. Each header pipe is provided with a plurality of flow holes, and at least two flow holes on each header pipe are arranged staggeredly in the circumferential direction. The plurality of flat tubes are connected in parallel between the two header pipes. At least a part of each flat tube extends meanderingly or around the header pipe. The two ends of each flat tube are respectively connected to the flow holes on the two header pipes. The plurality of flat tubes are arranged in one-to-one correspondence with the plurality of flow holes on each header pipe. According to the serpentine tube microchannel heat exchanger of the present invention, the length of a single refrigerant flow path can be shortened to reduce the flow resistance and pressure drop on the refrigerant side of the heat exchanger. In a refrigeration system applying this heat exchanger, the heat exchange efficiency can be improved. In addition, depending on environmental conditions such as the installation space size, the layout method of the flat tubes of the heat exchanger is diverse, which can expand the application occasions of the serpentine tube microchannel heat exchanger.

[0003] In view of the above related technologies, the inventor believes that there are the following defects: In the actual application process, it needs to be installed inside the boiler. However, currently, during the installation process, it is positioned and installed through pipe clamps, and it is difficult to perform the installation operation during the adjustment process, which affects the subsequent use efficiency of the serpentine pipe. Therefore, we propose a heat-insulating serpentine pipe for a biomass processing boiler to solve the above-mentioned existing problems. Summary of the Utility Model

When it needs to be installed, the positioning ring 2 is clamped into the surface of the tube body 1, and then the inner wall of the rubber ring 11 is clamped with the annular groove 6. When the reset spring 5 is loosened, the reset spring 5 resets the connecting rod 3 on the baffle 4, and then the surface of the positioning strip 12 contacts the surface of the tube body 1, so as to facilitate the clamping and positioning operation, and facilitate the subsequent disassembly and positioning of the pipeline during use, which is also convenient for subsequent staff to use, thereby improving the convenience of use of the annular tube.

[0029] Preferably, a plug-in hole for the plug-in rod 3 to pass through is opened on the positioning ring 2, and the inner wall of the plug-in hole is slidably connected to the surface of the plug-in rod 3.
