Abstract

The invention discloses a wet desulfurization parallel treatment device of high-sulfur-content flue gas. The device is characterized by comprising an absorption tower A, an absorption tower B, a booster fan, a flue baffle plate door A and a flue barrel plate door B, wherein the booster fan is provided with two flue gas outlets and is connected with the absorption tower A and the absorption tower B respectively; the flue baffle plate door A is arranged on a connecting pipeline between the booster fan and the absorption tower A; and the flue baffle plate door B is arranged on a connecting pipeline between the booster fan and the absorption tower B. The device can be used for refitting the conventional desulfurization device, can be applied to a newly-built desulfurization device, can adapt to the changes of different coal qualities and has the characteristics of high automatic degree, convenience in adjustment and operation stability.

Description

The wet method of high sulfur-containing smoke gas treating apparatus in parallel
Technical field
The present invention relates to the heat-engine plant wet flue gas desulfurization technique in energy environment protection field, is a kind of wet method treating apparatus in parallel of handling high sulfur-containing smoke gas, belongs to the electric power factory equipment technical field.
Background technology
In flue gas desulfurization technique, limestone-gypsum wet process of FGD technology is most widely used a kind of technology, and its nucleus equipment is the absorption tower.The bottom on absorption tower is the slurries ponds, and the top is provided with spray equipment, thereby flue gas and slurries counter current contacting are removed the SO in the flue gas 2, the flue gas after the washing is discharged from the top, absorption tower.
In recent years, China's energy supply goes wrong, a lot of power plant uncontrollable coal source, and the coal elemental composition that causes boiler of power plant to use alters a great deal, and the sulfur content in the flue gas produces very great fluctuation process, and desulfurizer often need be handled high-sulphur flue gas.And the raising gradually of the environmental requirement of country simultaneously.The frequent overload operation of desulfurizer causes desulfuration efficiency to descend the equipment heavy corrosion.
In order to reduce SO in the power-plant flue gas 2Discharge capacity, many power plant transform existing limestone-gypsum wet flue gas desulfurizer.Transformation is many so that former absorption tower body is transform as the master, increases the spray number of plies, strengthens the slurries pool volume as means, and this has caused the absorption tower too high again, has increased the operation power consumption.
Summary of the invention
For addressing the above problem, the purpose of this invention is to provide a kind of wet method treating apparatus in parallel of handling high sulfur-containing smoke gas.
In order to reach the foregoing invention purpose, technical scheme of the present invention realizes as follows:
A kind of wet desulphurization of high sulfur-containing smoke gas treating apparatus in parallel, it is characterized in that: comprise absorption tower A, absorption tower B, booster fan, damper door A and damper door B, described booster fan has two exhanst gas outlets and links with described absorption tower A and absorption tower B respectively, described damper door A is arranged on booster fan on the connecting pipe of absorption tower A, and described damper door B is arranged on booster fan on the connecting pipe of absorption tower B.
The present invention adopts said structure, can reduce the absorption tower height, save power consumption, exhaust gas volumn by rational distribution absorption tower A and absorption tower B, can satisfy the absorption tower design load 30%~180% between change, handle the flue gas of different sulfur content, the variation of ature of coal is had splendid adaptive capacity, guarantee the stable operation of system.The present invention is not only applicable to the transformation to the existing flue gas desulfur device of excuting a law, and is applicable to newly-built desulfurizer.Have the advantages that quantities is little, automaticity is high, easy to adjust, stable.
The present invention will be further described below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is apparatus of the present invention structural representations.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is further described:
Referring to Fig. 1, the present invention includes absorption tower A1, absorption tower B2, booster fan 3, damper door A4, damper door B5.Damper door A is arranged on booster fan on the connecting pipe of absorption tower A, and damper door B is arranged on booster fan on the connecting pipe of absorption tower B.Flue gas is divided into two strands and enters two flues by behind the booster fan, and the size of flow relies on damper door A and damper door B to regulate respectively.Two strands of flue gases enter absorption tower A and absorption tower B respectively by the bottom again, remove SO after Ta Nei and lime stone slurry reaction 2The slurries pond of absorption tower A and absorption tower B is not communicated with each other.All be provided with independently oxidation and spray equipment in the tower, isolated operation, convenient control.
When less or boiler load was low when amount of sulfur contenting in smoke, through calculating, flue gas can just be finished desulfurization in absorption tower A or absorption tower B.The another one absorption tower just can Close All so.Compare with the wet method series connection treating apparatus scheme of handling high sulfur-containing smoke gas, scheme in parallel is easy to control more, can realize complete independent operating, reduces expenses.
