Water curtain check-type super-purification smoke exhaust dedusting and desulfurization system

Abstract

The invention discloses a water curtain check-type super-purification smoke exhaust dedusting and desulfurization system, which comprises a smoke exhaust inlet tube, wherein the end part of the smoke exhaust inlet tube is connected to a flow rate control tube; the left side wall of a tube body of the flow rate control tube is provided with a guide rail; the internal thread of a lifting nut is adaptively provided with a rotating screw rod; two side walls of a conical extrusion cavity are respectively provided with one vibrating motor; the left side wall of the upper side of an inner cavity in a case body of an ultra-clean desulfuration case is provided with first diversion water curtain boards; the two first diversion water curtain boards and three second diversion water curtain boards are staggered; the bottom end of a tube body of a drainage through tube is communicated with a circulating filter box pump. The system is capable of solving the problem of weakened desulfuration effect caused by uncontrollable smoke feeding velocity in a traditional process, ensuring that sulfides in the smoke are fully absorbed and removed and the treated solvent also can be recycled, and further saving the solvent resource.

Description

technical field [0001] The invention relates to the related technical field of chemical flue gas purification, in particular to a water curtain and curtain type ultra-purified smoke and dust waste gas dedusting and desulfurization system. Background technique [0002] Chemical waste gas refers to the poisonous and harmful gas discharged from chemical plants in chemical production. Chemical waste gas often contains many types of pollutants, complex physical and chemical properties, and different toxicity, which seriously pollutes the environment and affects human health; the composition of chemical waste gas produced by different chemical production industries varies greatly, such as the waste gas produced by the chlor-alkali industry. Contains chlorine, hydrogen chloride, vinyl chloride, mercury, acetylene, etc. The waste gas produced by the nitrogen fertilizer industry mainly contains nitrogen oxides, urea dust, carbon monoxide, ammonia, sulfur dioxide, methane, etc. and c...

AI Technical Summary

Problems solved by technology

In order to protect the sanitation of the atmospheric environment that human beings depend on, it is necessary to purify and desulfurize the chemical waste gas. However, in the traditional process, the effect of subsequent dust removal and desulfurization is weakened due to the uncontrollable smoke inlet speed, which greatly limits the subsequent dust purification effect. , the subsequent dust removal process is also prone to pipe blockage, which affects the continuous use of the equipment, and the desulfurization effect is not good, it is difficult to ensure that the sulfur contained in the flue gas is fully absorbed and removed, and a single purification makes it impossible To ensure the smooth progress of the desulfurization work, there are still a lot of impurities in the discharged gas, and the liquid resources that have been used many times are discharged into the seawater after one use, and the surrounding air pollution has not been substantially improved.
