Therefore, thermal power generation is also the most important power generation system. The thermal power plant is divided into two by different combustion modes: coal-fired power plants and gas-fired power plants. The combustion chemical energy is converted into mechanical energy and then the mechanical energy is converted into electric energy in both coal-fired power plants and gas-fired power plants. However, sulfur impurities in coal are burned along with the combustion of coal, and harmful gases such as sulfur dioxide are generated, so that a power plant can desulfurize the coal before the combustion of the coal. Wet flue gas desulfurization is the desulfurization technology with the highest desulfurization rate in the current coal-fired power plant, and has the most wide application. The technology takes limestone slurry as a desulfurizing agent.
The slurry tank for wet desulfurization is characterized in that the slurry in the slurry tank is high in solid content and has fine particles, when the liquid level of the slurry tank is low, the slurry pump cannot completely empty the slurry in the slurry tank, and the slurry in the slurry tank can cause cavitation damage to the pump body, so that the pump body cannot work continuously, and the slurry is accumulated in the slurry tank. During equipment overhaul and shutdown, manual cleaning can only be adopted, if the equipment is not cleaned, solid particles in the slurry tank are deposited, and when the equipment is restarted, the large deposited particles can block the pipeline and damage the pump body, and meanwhile, the bottom of the slurry tank cannot be overhauled and maintained. Therefore, there is a need to develop a new device to better empty the slurry in the slurry tank.
