With the rapid development of economic construction, the demand for electricity is unusually strong. Coal fired power plants have to continuously increase their installed capacity, and the emissions of harmful gases also increase. The power energy structure is dominated by coal fired thermal power plants, which consume 400 million to 500 million tons of coal every year, and will produce tens of millions of tons of nitrogen, sulfide, etc, most of which are directly discharged into the air without treatment, seriously increasing environmental pollution.
The desulfurization limestone powder made from limestone is the main desulfurization process in thermal power plants, so how to make desulfurization limestone powder? What are the production and processing equipment for desulfurization limestone powder?
How to make desulfurized limestone powder? The particle size of limestone powder for desulfurization is required to be 250 mesh or 325 mesh, and 325 mesh limestone powder has better desulfurization effect. To prepare such fine limestone powder, Raymond mill and European version mill are mainly used, Traditional Raymond mills are widely used. In recent years, with the improvement of the requirements for the fineness of limestone powder and the need for energy conservation and emission reduction, more and more power plants begin to use European version mills to prepare limestone powder for desulfurization.
Process flow of limestone powder preparation for desulfurization: after the large limestone is crushed to the required particle size by jaw crusher, it is sent to the storage hopper by the elevator, and then sent to the main mill room of the European version mill for grinding in a uniform, quantitative and continuous manner by the vibration feeder. The limestone powder after grinding is blown up by the wind and graded by the powder concentrator. Limestone powder conforming to the fineness flows through the pipeline to the new isolated cyclone dust collector for separation and collection.
The collected finished limestone powder is sent to the limestone powder bin through the outlet and the conveyor for desulfurization. Unqualified particles are separated by the powder concentrator and then thrown to the cylinder wall. After falling along the cylinder wall, they return to the mill for grinding. The whole system operates under negative pressure, and the system dust does not overflow, so the site is clean.
It can be seen from the above processing technology that the equipment required for the production of desulfurization powder consists of jaw crusher, European version mill and other equipment. SMMVIK Machinery, as the manufacturer of desulfurization stone powder processing equipment for power plants, has Raymond mill, European version mill and other equipment for customers to choose from. You are welcome to consult in detail, and we look forward to your arrival.
