Petroleum refining fume purification device

Abstract

The invention discloses a petroleum refining fume purification device which structurally comprises a motor, an air inlet, a purification tower, an electronic control box, a fume outlet cylinder, a support rack and a fume discharge filtering device, wherein the motor is electrically connected with the outside and is connected with the electronic control box through a power supply wire; the motor is arranged at the front end of the purification tower; the air inlet is welded on the left side of the purification tower and is perpendicular to the purification tower in an L-shaped manner; the purification tower takes the shape of a cylinder consisting of three layers of rings; the fume discharge filtering device is connected with the top of the purification tower; and the electronic control box is a rectangular column. The petroleum refining fume purification device has the beneficial effects that a fume discharge pipeline can be assembled and disassembled, so that convenience can be brought to operators to clean and repair the device, and the time and the labor are saved; and due to adoption of an opening of the fume discharge pipeline, a fume filtering device matched with the opening is connected on the inner wall of the pipeline through buckles and is put inside and taken out in a rotation manner, so that the filtering layers can be conveniently replaced, dual filtration is achieved through different filtering layers on a filtering rack, the air discharge quality is improved, discharge of harmful substances is reduced, and body health is facilitated.

Description

technical field [0001] The invention relates to a petroleum refining smoke purification device, which belongs to the field of petroleum refining smoke purification devices. Background technique [0002] Oil refining refers to the processing and refining of the extracted oil in a refinery. Specifically, the oil is separated by distillation to produce fuel oils such as kerosene, gasoline, and fuel oil that are suitable for internal combustion engines, and the by-products are petroleum gas and residual oil; components heavier than fuel oil are chemically converted into fuels through processes such as heating and catalytic cracking. Some of these fuel oils are refined by processes such as hydrogenation. A large amount of waste gas will be generated in the process of petroleum refining. The exhaust gas contains a large number of particles and harmful gases, which will cause serious environmental pollution. Therefore, the exhaust gas generated in the process of petroleum refining...

Problems solved by technology

Existing filter devices easily lead to poor exhaust gas filtration effect

The smoke and dust produced in the process of petroleum refining has become an important factor of polluting the environment. Most of the smoke and dust contain a large amount of harmful substances, which are directly discharged into the air and cannot be removed, causing major damage to the environment and endangering human health.

However, due to the unreasonable structural design of the smoke purifier in the prior art, there are following defects. For example, when the filter layer of the smoke purification device reduces the adsorption rate of smoke dust, it is necessary to filter all the filter layers of the smoke purification device. Replacement, that is to say, during the replacement process, it is necessary to disassemble and reinstall all the filter layers. This maintenance process not only wastes a lot of manpower and material resources, but also affects the progress of purification.

[0003] Existing smoke exhaust pipes cannot be assembled and disassembled by threads, which is inconvenient for staff to maintain, and there is no filter frame on the smoke exhaust pipes, which cannot double filter the smoke, and cannot be the final check to reduce the emission of smoke impurities, which is not practical
