VentilationAir exchanging device special for distillation tower

Abstract

The invention relates to an ventilationair exchanging device special for a distillation tower. The ventilationair exchanging device comprises a protective shell, an exhaust opening is formed in the top of the protective shell and connected with an exhaust pipeline, and a one-way valve is arranged at the top of the exhaust pipeline; the exhaust pipeline is connected with a main pipe, the main pipeextends out of a spiral joint at the bottom of the protective shell, and an air inlet pipeline is connected into the spiral joint; the main pipe and the air inlet pipeline are fixed into the spiral joint through a fixing device, the air inlet pipeline is longer than the main pipe, and the top of the air inlet pipeline is connected with a filtering device; the filtering device is connected with a pipeline through a fixing piece, wherein the pipeline extends to the outer side of the shell; and a valve is arranged on the pipeline, and an air pressure meter is arranged at the bottom of the shell.According to the ventilationair exchanging device, the air inlet rate is increased through the air inlet pipeline, the cleanness and quality of inlet air are improved through the filtering device, a pressurizing chamber is connected with a nozzle, the work efficiency is improved, the main pipe has the abrasion-resistant, heat-resistant and compression-resistant effects, the service life is prolonged, and the firmness of pipe fittings is improved through the fixing piece.

Description

technical field [0001] The invention specifically relates to a special ventilation device for a distillation tower. Background technique [0002] During the long-term use of the distillation tower, due to the high temperature, the internal pressure increases, and it is necessary to ventilate it when the high pressure is too high, so as to ensure the safety of the structure. However, the existing ventilating device contains certain impurities in the gas. As a result, the working accuracy of the distillation tower is reduced after ventilation, resulting in a decline in product quality and increased costs. At the same time, the exhaust pipe is prone to damage in a long-term high-temperature environment, so it needs to be improved. Contents of the invention [0003] The object of the present invention is a special ventilation device for a distillation tower to solve the existing technical problems. [0004] In order to achieve the above object, the present invention provides ...
