Stirring device for desulfurization and denitrification

Abstract

The invention discloses a stirring device for desulfurization and denitrification. The device comprises a base, a base is assembled at the upper end of the base, and a stirring cavity is movably formed in the base. According to the stirring device for desulfurization and denitrification, through cooperation of a first driving wheel and a reset spring, a transmission rod drives a swing rod to slidein a reciprocating mode during sliding, so that a base plate drives stirring blades to swing, and the working effect that the stirring blades swing while rotating is achieved, a second driving wheelis arranged to be intermittently engaged with a sliding rod, and the gravity effect of the stirring cavity is matched, so that the sliding rod drives the stirring cavity to ascend and descend, the vibration stirring effect of the stirring cavity is achieved, and materials are effectively prevented from being deposited at the bottom of the stirring cavity, moreover, the two sides of the stirring cavity are slidably mounted with the guide rods through the assembly seats, and the vertical limiting springs are mounted at the lower ends of the assembly seats, so that the stirring cavity is lifted stably, and shaking generated in the lifting process of the stirring cavity is reduced.

Description

technical field [0001] The invention relates to a stirring device, in particular to a stirring device for desulfurization and denitrification. Background technique [0002] The method of generating electricity using the energy contained in combustibles is collectively referred to as thermal power generation. According to the power generation method, thermal power generation is divided into coal-fired steam turbine power generation, oil-fired steam turbine power generation, gas-steam combined cycle power generation and internal combustion engine power generation; thermal power generation still accounts for most of the electricity. In the market, thermal power plants produce a large amount of sulfur and nitrate waste gas from the coal burned for power generation, and these waste gases are discharged into the atmosphere to cause pollution and form acid rain. Thermal power plant desulfurization and denitrification equipment is used to deal with these waste gases containing a larg...

[0002] The method of generating electricity using the energy contained in combustibles is collectively referred to as thermal power generation. According to the power generation method, thermal power generation is divided into coal-fired steam turbine power generation, oil-fired steam turbine power generation, gas-steam combined cycle power generation and internal combustion engine power generation; thermal power generation still accounts for most of the electricity. In the market, thermal power plants produce a large amount of sulfur and nitrate waste gas from the coal burned for power generation, and these waste gases are discharged into the atmosphere to cause pollution and form acid rain. Thermal power plant desulfurization and denitrification equipment is used to deal with these waste gases containing a large amount of sulfur and nitrate; In order to protect the environment, the exhaust gas produced by thermal power plants is usually treated and then discharged. In the process of treatment, calcium hydroxide slurry needs to be used, and a stirring device is required in the configuration of calcium hydroxide slurry. Traditional stirring devices are easy to exist The area that the stirring blade cannot touch, and the traditional stirring device operates in a single mode, and the stirring is not uniform, which easily leads to calcium hydroxide deposition at the bottom, resulting in unqualified calcium hydroxide slurry configuration, which affects the subsequent desulfurization and denitrification treatment. Reduced desulfurization and denitrification efficiency; therefore, it is necessary to improve the existing technology
