Description
Technical field
The utility model relates to a kind of wet desulphurization lime stone slurry feeding device, belong to flue gas desulfurization technique field.
Background technology
Limestone-gypsum method wet desulphurization, using lime stone as absorbent, sulfur dioxide in flue gas in absorption tower etc.
Material, absorption process needs constantly to supplement lime stone slurry to absorption tower and maintain to react persistently to carry out.
The commonly used lime stone slurry of existing lime stone slurry compensation process is added directly into the method within absorption tower,
This improvement being directly added into mode, being unfavorable for absorbing environment, and then it is easily reduced desulfuration efficiency.
Content of the invention
The purpose of this utility model is to overcome the shortcomings of that existing absorption tower lime stone slurry supplies slurry mode, provides a kind of logical
Cross the feed postition optimizing lime stone slurry in wet desulphurization, improve sprayed slurry ph value and lime stone in desulfuration absorbing tower and contain
Amount, improves the absorption environment of flue gas and the materials such as sulfur dioxide during serous adverse flow washing, and then it is de- to improve the wet method of desulfuration efficiency
Sulphur lime stone slurry feeding device.
The utility model is to realize by following technical solution: a kind of wet desulphurization lime stone slurry feeding device, it includes
One adopts lime stone as the absorption tower of absorbing sulfur dioxide in flue gas, and in described absorption tower, top is provided with downwards
The spray thrower of spray lime stone slurry, the external circulation pipe of this spray thrower is connected to the bottom in absorption tower, and in circulation pipe
In be serially connected with an absorption tower slurry circulating pump；This absorption tower slurry circulating pump will fall into suction with after flue gas adverse current washing in absorption tower
The lime stone slurry receiving tower inner bottom part is re-fed in absorption tower；One external limestone slurry liquid pool is connected to described by delivery pipe
On the circulation pipe of absorption tower slurry circulating pump inlet side, described delivery pipe is serially connected with least limestone slurry liquid pump respectively
With a flow control valve.
As preferred: described spray thrower by the annular shower with multiple nozzles for the horizontal or is connected together
The many showers that are arranged in parallel are constituted, and absorption tower inner bottom part is provided with lime stone slurry storage tank, the lower end of described circulation pipe from
Absorption tower bottom side wall stretches in described lime stone slurry storage tank.
Lime stone slurry described in the utility model pumps up pressure by lime stone slurry, after flow control valve, directly
Access absorption tower serum recycle pump intake, so can increase the limestone slurry in the ph value and slurries of sprayed slurry in absorption tower
Liquid concentration, improves the absorption tower environment of the materials such as sulfur dioxide, improves desulfuration efficiency.
The utility model has structure composition rationally, using easy to operate, safety, can improve spray slurry in desulfuration absorbing tower
Liquid ph value and limestone content, improve the absorption environment of flue gas and the materials such as sulfur dioxide during serous adverse flow washing, and then improve
The features such as desulfuration efficiency.

It is connected to the bottom in absorption tower 4, and be serially connected with an absorption tower slurry circulating pump 3 in circulation pipe 6；This absorption tower serum recycle
Pump 3 falls into absorption tower inner bottom part with flue gas adverse current lime stone slurry 7 after washing in absorption tower 4 is re-fed in absorption tower 4；One
External limestone slurry liquid pool 8 is connected on the circulation pipe 6 of described absorption tower slurry circulating pump 3 inlet side by delivery pipe 9,
It is serially connected with least one limestone slurry liquid pump 1 and a flow control valve 2 respectively in described delivery pipe 9；Described flow control valve 2
The supplementary input of lime stone slurry can be carried out by external intelligent controller.This intelligent controller can select existing public affairs
The product known or the simple transformation of process form.
Shown in figure, described spray thrower 5 by the annular shower with multiple nozzles for the horizontal or is connected together
Many be arranged in parallel showers constitute, absorption tower 4 inner bottom part is provided with lime stone slurry storage tank 10, described circulation pipe 6
Lower end is stretched into described lime stone slurry storage tank 10 from absorption tower 4 bottom side wall.For ensureing the normal operation of facility, this reality
With new described all being made using abrasion-proof corrosion-proof corrosion material with lime stone slurry contact component.
These are only preferred embodiment of the present utility model, be not limited to the utility model, all in this practicality
Any modification, equivalent and improvement made within new spirit and principle etc., should be included in guarantor of the present utility model
Within the scope of shield.
