Embodiment Construction

[0021] Embodiment Referring to Fig. 1, this wet desulfurization and smoke exhaust integrated device has a spray layer and a mist eliminator inside. The diameter of the upper tower body 3 decreases successively, the transition section 4 between the lower tower body and the middle tower body, and the transition section 5 between the middle tower body and the upper tower body are all in the shape of a cone, and the lower tower body is a circulating slurry pool; the middle tower body is for desulfurization reaction There is a lime slurry spray layer in this section; the tower body in the upper section is the smoke exhaust section. The length of the smoke exhaust section is greater than the length of the desulfurization reaction section, the length of the desulfurization reaction section is greater than the height of the circulating slurry pool, the lower part of the desulfurization reaction section is connected to the smoke inlet pipe 6, and the insertion angle c between the smoke ...

Abstract

A wet-type desulfurization and smoke exhaust integrated device, which is internally equipped with a network of spray nozzles interwoven by at least two parallel spray main pipes, spray branch pipes branched from the spray main pipes, and two-way nozzles branched from both sides of the spray branch pipes. Sprinkler and demister, the device is a five-section variable-diameter vertical circular tower shape, the diameter of the lower tower body, the middle tower body to the upper tower body decreases successively, the transition section between the lower tower body and the middle tower body, and the middle tower body The transition section with the upper tower body is in the shape of a truncated cone. The lower tower body is a circulating slurry pool, the middle tower body is a desulfurization reaction section, and the upper tower body is a smoke exhaust section. The length of the smoke exhaust section is greater than the length of the desulfurization reaction section. Greater than the height of the circulating slurry tank, the lower part of the desulfurization reaction section communicates with the smoke inlet pipe. The invention provides an economical and convenient method for clean flue gas discharge, which can save the construction cost of anti-corrosion flue and separate chimney, reduce system resistance, reduce operating power consumption and operating cost, and greatly save engineering cost.

Description

(1) Technical field [0001] The invention relates to a smoke exhaust device for flue gas desulfurization. (two), background technology [0002] In the existing flue gas wet desulfurization process, the flue gas needs to be sprayed by the reaction tower to remove harmful sulfides, but the flue gas after spraying has the characteristics of high humidity and strong corrosion. In order to remove the sulfur in the flue gas, a reaction tower for flue gas reaction must be built. After the clean flue gas washed by the reaction tower is heated to a certain temperature, it is sent back to a separately constructed chimney for discharge, or directly sent to the collection unit without heating. Chimney emissions with special anti-corrosion measures. No matter which method is adopted, the construction cost of the flue and anti-corrosion will be increased. At the same time, due to the resistance of the flue and the heating device, the operating power consumption will increase, that is, the...
