Description

Technical Field

[0001] The utility model relates to the technical field of chimneys, in particular to an anti-corrosion, dust-collecting and energy-saving chimney. Background Art

[0002] Anti-corrosion, dust-collecting and energy-saving chimneys refer to chimneys used in chemical, manufacturing and other industries. They not only have the emission function of ordinary chimneys, but also have the functions of anti-corrosion and dust collection. Since the flue gas emitted in the chemical production process contains a variety of corrosive gases, the chimney needs to be specially treated with anti-corrosion to extend its service life. Corrosion-resistant materials such as stainless steel, high-strength corrosion-resistant steel, etc. are used. Anti-corrosion, dust-collecting and energy-saving chimneys are important environmental protection facilities in chemical, manufacturing and other industries. They can not only ensure the safety and stability of production, but also reduce the impact on the environment, which is in line with my country's requirements for environmental protection and energy conservation and emission reduction.

[0003] The currently used anti-corrosion dust-collecting energy-saving chimneys, in actual operation, fail to effectively realize heat recovery and reuse, resulting in the failure to fully utilize the valuable resource of thermal energy to a certain extent.

[0004] Patent document CN201507144U discloses an anti-corrosion dust collection energy-saving chimney, "its chimney body (3), characterized in that an inner lining wall of the chimney body (3) is provided with an inner bore spiral line (1) with a spiral angle of 10° to 80°; an outlet (2) of a flue (4) located outside the lower end of the chimney body (3) is connected to the inner bore spiral line (1), and the flue (4) and the inner bore spiral line (1) are smoothly connected. Compared with existing chimneys, it has a stable structure, good environmental protection effect, extended service life, and relatively low cost. The invention is cheap; the environmental protection effect can be improved by 25-45%, the self-resistance can be reduced by 20%, and thus the power consumption of the induced draft fan can be reduced by about 8.5%; the flue gas swirls in the tube, and dust can be collected by 30-80%; the chimney of the device is used for wet dust removal and wet desulfurization, the lining is intact, there is no corrosion at all, and it is suitable for various chimneys. However, the anti-corrosion dust collection and energy-saving chimney in the above-mentioned public documents mainly considers the problems of high structural stability and good environmental protection effect, but does not consider the problem of heat recovery. Therefore, it is necessary to develop an anti-corrosion dust collection and energy-saving chimney. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The utility model installs a heat storage box to facilitate the anti-corrosion dust collection and energy-saving chimney to recover heat. When the anti-corrosion dust collection and energy-saving chimney is used, the bottom of the chimney body is connected with the smoke exhaust pipe. When the smoke flows upward, it will flow through the inside of the frame and contact the heat absorption pipe, so that the water pump works to extract the water source inside the heat storage box. The extracted water source will enter the heat absorption pipe through the first connector to flow. When the water source flows, it will absorb and carry the surrounding heat. The water source carrying the heat will flow back through the second connector into the heat storage box for storage, so as to achieve the purpose of recycling, storing and reusing the heat, effectively reduce the loss of heat, and achieve the effect of energy saving;

[0013] 2. The utility model can improve the anti-corrosion effect of the anti-corrosion dust collecting energy-saving chimney by installing an anti-corrosion layer. The anti-corrosion layer is mainly designed to resist the erosion of acidic substances, high temperature and other corrosive media contained in the flue gas during the operation of the chimney, and can extend the service life of the chimney body.
