Automatic filter element replacement type flue gas desulfurization device

Abstract

The invention discloses an automatic filter element replacement type flue gas desulfurization device which comprises a base, a support, a feeding mechanism, a bracket, a cylinder, a push plate, a rotating shaft, a first gear, a lock head, a magnet, a first servo motor, a second gear, a fixing rack, a cylinder, a liquid separation mechanism, a filter element mechanism, a locking mechanism, a placement rack, a tank body, a diffusion pipe, a supporting plate, a water tank, an atomizing nozzle, a partition plate, an insertion pipe, an air outlet pipe, a liquid inlet pipe and a liquid outlet pipe. The device is simple in structure and is capable of automatically replacing the filter element mechanism, greatly reducing the labor intensity of an operator, improving the production efficiency and effectively preventing toxic gases from causing injuries to body health of the operator; meanwhile, the liquid medicine is atomized and subjected to primary desulfurization with flue gas, and the flue gas subjected to the primary desulfurization is introduced into the liquid medicine so as to be subjected to secondary desulfurization, so that the flue gas desulfurization is uniform and complete, and the desulfurization effect is excellent.

[0002] With the development of industry and the improvement of people's living standards, the thirst for energy is also increasing. SO2 in coal-fired flue gas has become the main cause of air pollution. Reducing SO2 pollution has become the top priority of today's atmospheric environmental governance. Many smokers The gas desulfurization process has been widely used in industry. Among them, the wet desulfurization technology is widely used because of its mature technology and simple process. The process of wet desulfurization is generally as follows: the flue gas is directly passed into the alkaline The neutralization reaction can be carried out in the desulfurization irrigation of the liquid medicine. After the reaction solution is filtered, it is circulated and pumped into the desulfurization tower for neutralization reaction, and the liquid medicine is replenished according to the pH value until the desulfurization is completed. Since the flue gas is directly passed into the alkaline medicine Local desulfurization tends to be uneven during liquid desulfurization, resulting in low desulfurization efficiency. At the same time, a filter device with a filter element is required for filtration, and the filter element needs to be cleaned and maintained after a period of use. Most of the existing methods are manual replacement of the filter element. Not only is it time-consuming, but staying in a work site with sulfide for a long time will damage the health of the operators
