Description
Technical Field
The invention belongs to the technical field related to gas treatment, and particularly relates to a high-efficiency gas desulfurization device.
Background
In industrial production, a large amount of acid waste gas is generated, and the acid rain effect is caused by direct discharge of the gas, so that certain liquid alkali neutralization and treatment are required. Traditional exhaust gas desulfurization device sprays for adopting the shower head to get into reaction unit's waste gas, but because there is the dead angle in the reactor, the alkali lye concentration of each position differs, and the waste gas that gets into the reactor moreover can not fully contact with alkali lye, consequently needs to design a better device of desulfurization effect.
The water film dust collector is a kind of purifying equipment which uses dust-containing gas to impact the water film on the inner wall of dust collector or other special members and is made by some method to make the dust captured by the water film and the gas purified.
The desulfurization equipment is used in desulfurization and dust removal industries of coal-fired boilers, is wide in application, can perform wet dust removal, wet desulfurization and can also perform dust removal, desulfurization and dust removal integration, is suitable for dust removal and desulfurization of coal-fired circulating fluidized bed boilers of power stations, can also be used for wet desulfurization and dust removal and flue gas purification of coal-fired chain boilers, is high in sulfur dioxide removal efficiency, thorough in tail gas purification, and applied to equipment for removing hydrogen fluoride and kiln tail gas acidic waste gas in the furnace and kiln industries, and can be used for desulfurization of pellets and sintering machine tail gas. The waste ammonia water purification efficiency of the desulfurizer is extremely high, the original flue gas SO2 is removed to below 120mg/m3 from 11000mg/m3, and the desulfurizer is widely applied to the field of pellet flue gas in steel mills. Is a low-resistance and high-efficiency wet dust removal desulfurization device and a novel desulfurization device environment-friendly product.
The water film desulfurization dust remover combined with the dust remover forms a water film flowing from top to bottom in the dust remover, and utilizes the rotating inertia force of flue gas to throw dust particles to the water film to be taken away by water flow, thereby achieving the purpose of dust removal. The existing dust remover has the problems of low desulfurization efficiency, high energy consumption, large volume, unstable equipment performance and the like, and the main reasons are as follows: the cleaning solution is not fully mixed and contacted with gas and dust, the cleaning effect is poor, the dust removal efficiency is low, wherein the gas-liquid contact is not fully mixed, the contact time is short, and the poor cleaning gas effect is the main reason of low desulfurization efficiency, SO that the SO2 discharge concentration does not reach the standard, and the discharge amount is large.
