A flue gas desulfurization purification device capable of recovering waste heat for industrial boilers

Abstract

The invention relates to a flue gas desulfurization purification device capable of recovering waste heat for industrial boilers, comprising a smoke inlet and a first filter screen, a low-resistance cyclone dust collector is arranged on the left side of the smoke inlet, and the low-resistance cyclone dust collector A particle recovery tank is placed at the lower end of the low-resistance cyclone dust collector, and a waste heat treatment pipeline is inlaid on the upper end of the low-resistance cyclone dust collector, and a first spray valve is connected to the inner upper end of the waste heat treatment pipeline, and a first connecting pipeline is installed on the upper end of the first spray valve . The beneficial effects of the present invention are: through the first spray valve, it can spray the medicinal solution in the medicine box on the flue gas entering the waste heat treatment pipeline in the form of mist, and can initially contact the particles in the flue gas, and the particles Wet and settle to the lower end of the waste heat treatment pipe, and react with the alkaline substances in the flue gas to neutralize, initially purify the flue gas and reduce the temperature of the flue gas at the same time, to prevent the flue gas from being discharged directly when it is too high, causing the environment to be affected Pollution.

Description

technical field [0001] The invention relates to the technical field of flue gas desulfurization and purification devices, in particular to a flue gas desulfurization and purification device for industrial boilers capable of recovering waste heat. Background technique [0002] In recent years, the problem of air pollution has become more and more serious. As a large developing country, my country will still face the severe situation of increasing air pollution for a long time to come. Prominently, the problem of atmospheric environmental pollution control has continuously attracted extensive attention from all over the world. The development of efficient, energy-saving, and cost-effective flue gas purification equipment and technologies is a fundamental solution to environmental protection issues. [0003] Existing flue gas desulfurization and purification devices can only perform simple purification of flue gas, and the effect of purification is not very satisfactory. The dis...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a flue gas desulfurization purification device for industrial boilers that can recover waste heat, so as to solve the problem that the existing flue gas desulfurization purification device proposed in the above background technology can only simply purify the flue gas, and the effect of purification It is not very ideal, the exhausted flue gas is still not up to standard, and the waste liquid generated during the purification process cannot be reused, but directly discharged, which is easy to pollute the environment. At the same time, the heat in the exhausted flue gas Very high, will cause air pollution problems
