Problems solved by technology

[0004] The purpose of the present invention is to provide an integrated device for extracorporeal oxidation, high-efficiency desulfurization and dust removal with double towers and double cycles, so as to solve the problem that the current desulfurization and dust removal devices for flue gas on the market proposed by the above-mentioned background technology cannot meet people's needs due to relatively imperfect technology. , the effect of the desulfurization and dust removal device in the prior art is relatively weak, and the flow rate of the flue gas in the desulfurization tower is too fast and the residence time is too short, which greatly affects the mass transfer and oxidation reaction of the flue gas, and the slurry spraying in the conventional technology It is inevitable that the nozzles will be clogged after a long period of use, but in the prior art, the nozzles and the accompanying components are placed in the tower, which will cause more cumbersome problems in later maintenance

Abstract

The invention discloses a double-tower double-circulation in-vitro oxidation efficient desulfurization and dust removal integrated device. The device comprises a raw material powder bin, a boiler body, a discharging pipeline and a flushing pump. The raw material powder bin is connected with a pulping machine, the pulping machine is provided with a slurry box, the slurry box is connected with a circulating water pool, and the circulating water pool is provided with an oxidation fan; an air inlet is formed in the main body frame, an induced draft fan is mounted on the air inlet, a flue gas pretreatment chamber is arranged in the main body frame, an annular pipeline is mounted above the flue gas pretreatment chamber, a slurry tank is arranged below the flue gas pretreatment chamber, and a discharging pipeline is connected below the slurry tank; and the flushing spray header is connected with a flushing pump. According to the double-tower double-circulation in-vitro oxidation efficient desulfurization and dust removal integrated device, the spent slurry can be circulated out of a body to be subjected to oxidation and density detection, and treatment can be carried out in time when the desulfurization and dust removal efficiency is reduced, so that the device is more stable in practical application.

Description

technical field [0001] The invention relates to the technical field of flue gas desulfurization and dust removal, in particular to an integrated device for extracorporeal oxidation and high-efficiency desulfurization and dust removal with two towers and two cycles. Background technique [0002] With the continuous progress of society, a large number of industries have sprung up, and at the same time, they have brought environmental pollution. Therefore, desulfurization and dust removal devices for flue gas have been vacated. The flue gas desulfurization dust collector has high economic, social and economic benefits. It has broad prospects in the desulfurization and dust removal of industrial boilers and industrial kilns. This product starts from improving the absorption rate, strengthens the gas-liquid two-phase kinetic function, and the gas phase and liquid phase are constantly alternately transposed, which is beneficial to the mass transfer reaction process of waste gas. ...
