Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a connecting pipe of a waste gas treatment device. Background Art

[0002] Waste gas refers to toxic and harmful gases discharged by humans in the process of production and life, especially chemical plants, steel mills, pharmaceutical plants, coking plants, refineries, etc., as well as life waste gas caused by human life. The waste gas emitted has a strong odor, seriously pollutes the environment and affects human health. Industrial waste gas emitted by various production enterprises is an important source of air pollutants. If a large amount of industrial waste gas is discharged into the atmosphere without being treated and meeting the standards, it will inevitably reduce the quality of the atmospheric environment, cause serious harm to human health, and cause huge losses to the national economy. Toxic and harmful substances in industrial waste gas can enter the human body through the respiratory tract and skin. Long-term low concentration or short-term high concentration exposure can cause temporary and permanent lesions in the respiratory, blood, liver and other systems and organs of the human body. In particular, benzopyrene polycyclic aromatic hydrocarbons can directly cause cancer in the human body, which has attracted great attention from humans.

[0003] The exhaust gas emission pipe is mainly used for the transportation and emission of exhaust gas. During the emission process, the exhaust gas is adsorbed and filtered by the filter installed on the pipe. In order to ensure the permeability of the filter during adsorption treatment, the filter needs to be removed and cleaned regularly. However, the frequent installation and disassembly of the filter will lead to insufficient sealing between the installation frame and the exhaust gas pipe after installation, causing leakage of some unfiltered exhaust gas, which is inconvenient for the use of the exhaust gas pipe. For this reason, we propose a connecting pipe for the exhaust gas treatment device. Summary of the invention

[0004] The purpose of the utility model is to provide a connecting pipe of an exhaust gas treatment device to solve the problems raised in the above background technology.

It can scrape off debris attached to the filter plate 6 and reduce the frequency of disassembly and cleaning of the filter plate 6.

[0026] At the same time, the height of the installation chamber 4 is greater than the outer diameter of the pipe body 1, and a baffle 17 is fixed on the side of the filter frame 5 away from the filter plate 6. The baffle 17 is located on both sides of the pipe body 1. The height of the scraper block 7 is less than the height of the baffle 17, so as to minimize the obstruction to the flow of exhaust gas in the pipe body 1.

[0027] It is worth noting that a compression spring 15 is provided on the outside of the pull rod 8. One end of the compression spring 15 is fixed to the scraper block 7, and the other end is fixed with a retaining ring 16.
