Flue gas deacidifying device and flue gas deacidifying method

Abstract

The invention discloses a flue gas deacidifying device, the flue gas deacidifying device comprises a tower body, the tower body is internally provided with a first spraying part and a second sprayingpart, the first spraying part is used for spraying out a circulating fluid to deacidify the flue gas, the second spraying part is located at the upper part of the first spraying part, a plurality of sieve plate parts used for triggering the diffusion of the circulating fluid to deacidify the flue gas when the circulating fluid is sprayed out are further arranged in the inner part of the tower body, the sieve plate parts are located between the first spraying part and the second spraying part, and a filtering part used for separating the gas from the liquid is further arranged at the upper partof the second spraying part. The invention further discloses a flue gas deacidifying method. The flue gas deacidifying device and the flue gas deacidifying method have an efficient deacidifying effect, are low in use cost, and are stronger in applicability particularly under the conditions that the concentration of the acid of the flue gas is relatively high and the space is limited.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a flue gas deacidification device. The invention also relates to a flue gas deacidification method. Background technique [0002] With the rapid development of my country's economic construction, energy and environmental issues have attracted more and more attention. The flue gas formed after garbage incineration is the main source of air pollution. Before being discharged, it must be treated by some equipment to purify the flue gas, and it can only be discharged into the atmosphere after reaching the emission standard. [0003] In the existing technology, in the incineration of waste, especially in the incineration of medical waste and hazardous waste, the deacidification effect of ordinary deacidification devices is average, and it is difficult to achieve the required purification level. To meet the discharge requirements, further purification is required dea...

Problems solved by technology

[0003] In the existing technology, in the incineration of waste, especially in the incineration of medical waste and hazardous waste, the deacidification effect of ordinary deacidification devices is average, and it is difficult to achieve the required purification level. To meet the discharge requirements, further purification is required deal with

In the actual purification process, the deacidification effect of ordinary spray towers has been difficult due to various reasons such as processing capacity and process flow in some waste treatment plants, especially in the case of high acid concentration in flue gas and limited space. Meet the functional requirements of modern waste treatment plants

[0004] Therefore, how to avoid the unsatisfactory deacidification effect of the deacidification device due to the high acid concentration of the flue gas and the limitation of the site is a technical problem that those skilled in the art need to solve at present.
