Embodiment Construction

[0027] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0028] Preferred embodiment:

[0029] This preferred embodiment discloses a flue gas purification tower, the flue gas purification tower is mainly aimed at desulfurization and denitrification of flue gas by activated coke method. The flue gas purification tower includes a tower body, at least one air inlet 1 arranged at the bottom of the tower body, at least one gas outlet 2 arranged at the top of the tower body, at least one layer of active coke layer 3 located in the tower body, and at the inlet 1 The baffle plate 4 arranged at the point where the flue gas flow changes direction, wherein, the flue gas flow at the air inlet 1 is parallel to the active coke layer 3 flow, such as figure 1 with figure 2 shown.

[0030] Such as image 3 with Figure 4 As shown, the baffles 4 are straight plates, ...

Abstract

The invention discloses a flue gas purification tower, belongs to the technical field of flue gas purification equipment, and aims at solving the problem that the flue gas flow fields in the existing flue gas purification towers are non-uniformly distributed. The flue gas purification tower provided by the invention comprises a tower body, at least one gas inlet, at least one gas outlet, at least one active coke layer and a baffle plate, wherein the at least one gas inlet is formed in the bottom of the tower body; the at least one gas outlet is formed in the top of the tower body; the at least one active coke layer is located in the tower body; the baffle plate is arranged at a flue gas flow turning place of the gas inlet; the baffle plate is a straight plate, an arc plate, a straight-arc plate or a straight-arc-straight plate; the straight-arc plate comprises a straight section and an arc section which is connected with the straight section; and the straight-arc-straight plate comprises a straight section which is located in the vertical direction, a straight section which is located in the horizontal direction and an arc section which is connected between the two straight sections. The glue gas purification tower disclosed by the invention can enable a gas flue flow field in the tower to be distributed uniformly, so as to improve the glue gas adsorption efficiency in the coke layer.

Description

technical field [0001] The invention relates to the technical field of flue gas purification equipment, in particular to a flue gas purification tower. Background technique [0002] With the rapid development of the economy, the environmental problems brought about by resource-based production are becoming more and more serious. Among them, the flue gas released by power plants, steel mills, coking plants, glass ceramic enterprises, etc. has caused serious pollution to the atmospheric environment. Activated coke flue gas desulfurization and denitrification technology: not only can remove SO in flue gas at the same time 2 It also has the advantages of no water consumption, no secondary pollution, effective removal of pollutants such as dust and heavy metals (such as mercury) in flue gas, and the ability to regenerate sulfur resources through adsorbents. The removal effect of activated coke flue gas desulfurization and denitrification technology is affected by the internal st...
