Desulfurization and dedusting integrated device

Abstract

The invention discloses a desulfurization and dedusting integrated device, which comprises an exhaust pipe, a cooling pipe, a gas outlet pipe, an air cylinder and a treatment tank. The treatment tankis internally provided with a treatment agent, the exhaust pipe is inserted into the treatment agent, a grating plate is arranged below the exhaust pipe, the cooling pipe is provided with a water inlet and a water outlet, the middle of the cooling pipe is arranged in the exhaust pipe, a filter screen is arranged in the lower portion of the treatment tank, and the lateral side of the treatment tankis provided with a sewage outlet, an agent inlet and an agent outlet. The gas outlet pipe is arranged on the upper lateral side of the treatment tank, the lower end of the gas outlet is coiled on theexhaust pipe, a telescopic rod of the air cylinder extends into the treatment tank, the lower portion of the telescopic rod of the air cylinder is connected with a circular fixing plate, and the outer side of the fixing plate is connected with an open-side-up annular elastic plate. The desulfurization and dedusting integrated device has advantages that simultaneous cooling, dedusting and desulfurization can be realized, and novel structure, convenience in operation and low cost are realized as well; waste gas is separated into a plurality of branches at an outlet of the exhaust pipe to reactwith the treatment agent; by dual stirring effects of the elastic plate, thoroughness in waste gas desulfurization is realized, and discharged gas basically reach desulfurization standards.

Description

technical field [0001] The invention belongs to the technical field of flue gas purification, and in particular relates to an integrated device for desulfurization and dust removal. Background technique [0002] With the progress of society and the development of economy, the pollution of power plants to the atmospheric environment has been widely concerned by people. The SO2 and dust emitted by coal-fired thermal power units are more harmful to the environment. Therefore, it is necessary to effectively reduce pollutants. To improve the impact on the environment, the current main treatment technology is wet desulfurization, and the desulfurization tower used is a large-scale equipment, which is suitable for use in large-scale enterprises, but for some small factories, large-scale equipment is not required, and the cost is high , it is necessary to develop a simple and easy equipment to desulfurize and remove dust. Contents of the invention [0003] In order to solve the a...
