Abstract
The invention discloses a flue gas purification device using gas-liquid contact. The device comprises a spray tank, a support, a liquid supply pump and a liquid storage tank; the spray tank provided with a spray pipe and a hydraulic pump is directly arranged on the air outlet of a chimney through the support; liquid in the liquid storage tank is pumped from the liquid inlet of the spray tank to the spray tank by the liquid supply pump through a pipeline arranged on the inner wall of the chimney; the spray pipe and the hydraulic pump are arranged at the bottom of the spray tank; and the liquid is compressed by the hydraulic pump and sprayed out through the spray pipe in a mist mode and then falls into the chimney. By using the device, an additional spray tower is not required to be constructed; and the device is short in construction period and easy to maintain.
Description
Technical field
The present invention relates to stack gas cleaning, is a kind of purifying flue gas XO that is used for specifically
2Device.
Background technology
China is the few country of coal heavy wool, accounts for total more than 70% of electric weight in the whole nation with coal power generation at present.Can China be again energy consumption big country, normally guarantee supply of electric power, has been related to whether normal development of China's economy, and whether people's lives normal key factor.Other energy are low relatively for coal combustion heat production cost, so coal is the main force of the present energy supply of China, but coal can produce when burning in a large number to human body and harmful naturally XO
2Gas is like nitrogen dioxide, carbon dioxide, sulfur dioxide etc.The main at present spray of gas-liquid contact or the mode of washing of adopting handled this type pernicious gas; Traditionally; Adopting this mode generally is that flue gas need be fed in the custom-designed spray column; This through transforming the user that just can reach discharge standard, increased construction cost and maintenance cost undoubtedly, and construction period is long for needs.
Summary of the invention
The object of the invention provides a kind of need not build special spray column, effluent gas purification equipment easy for installation.
Realize that the technical scheme that above-mentioned purpose adopted is following:
Effluent gas purification equipment; It comprises spraying box, support, solution feed pump and liquid storage tank; Spraying box is fixed on the support, and support is installed on the gas outlet of cigarette fontanel, and solution feed pump gets into spraying box through the pipeline that is installed in cigarette fontanel inwall by the inlet of spraying box with the liquid in the liquid storage tank; The bottom of said spraying box is provided with several spray equipments, and liquid falls in the cigarette fontanel after by the vaporific ejection of spray equipment.
Further, the inlet at spraying box is equipped with the ball-cock assembly that is used to control liquid supply rate.
Further, said spraying box is provided with escape pipe, and an end of escape pipe is on the liquid level of spraying box, and the other end is in the cigarette fontanel.
Further, said spray equipment comprises hydraulic pump, shower and spray head, and the inlet of shower is connected to the bottom of spraying box through hydraulic pump, and spray head is equipped with in the outlet of shower.
Further, said solution feed pump is the non-negative-pressure variable frequency pump.
Beneficial effect: effluent gas purification equipment of the present invention can simply be installed on the existing cigarette fontanel, need not build extra spray column, and it is short to transform construction period, safeguards simple; Because the cigarette fontanel shrinks when making progress gradually, therefore can reduce the quantity of shower; The pipeline that is installed in the cigarette fontanel can prevent that pipeline from freezing in the winter time, can also reduce the power that flue gas rises to getting into the flue gas cools of cigarette fontanel simultaneously, helps the sedimentation of dust; The escape pipe of spraying box keeps the case internal pressure consistent with atmospheric pressure in the time of can making spraying box work, also can be after ball-cock assembly be malfunctioning, and liquid can be discharged from escape pipe.

Wherein, 1-chimney, 2-flue, 3-liquid storage tank, 4-pipeline; The 5-spraying box, 6-support, 7-liquid back pipe, 8-blow-off pipe, 9-dredge pump; The 10-solution feed pump, 11-collecting pit, 21-tarpaulin, 31-liquid storage tank inlet, 32-screen pack; The 33-sewage draining exit, 51-ball-cock assembly, 52-escape pipe, 53-shower, 54-hydraulic pump.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Purifier of the present invention is applied in the flue gas emissions processing in thermal power plant; A liquid storage tank is set near the cigarette fontanel earlier; Liquid storage tank is provided with liquid back pipe and the blow-off pipe that connects cigarette fontanel bottom collecting pit, and the liquid back pipe opening is provided with filtering head at an end of liquid back pipe on the blow-off pipe opening; Keep liquid storage tank equal through liquid back pipe with the liquid level in the collecting pit; On blow-off pipe, be connected with dredge pump, in liquid storage tank, be provided with screen pack, the position of screen pack is between liquid back pipe opening and blow-off pipe opening.The flue aperture position that is arranged in the cigarette fontanel will be higher than the liquid level of liquid storage tank, above the opening of this flue, tarpaulin is installed.Spraying box is welded on the irony support, and support is fixed on the gas outlet of cigarette fontanel top again.The non-negative-pressure variable frequency pump is equipped with at the place at the liquid storage tank liquid outlet, is used for to the spraying box feed flow, and the pipeline that is connected with the non-negative-pressure variable frequency pump discharge gets in the cigarette fontanel, and upwards arranges along cigarette fontanel inwall, is connected with the inlet that is located at the spraying box side at last.
Spraying box is sealing; Be provided with the shower of row's different length in the lower end of spraying box, the inlet of shower is connected to spraying box through hydraulic pump, and the outlet of shower is connected to spray head; Because each spray head is in different height; Can in chimney, generate the water smoke of different levels like this, water smoke is better contacted with flue dust with dusty gas, reach the purpose of abundant absorption cleaning; The quantity of the spray equipment of being made up of shower, hydraulic pump and spray head can change according to the size of cigarette fontanel gas outlet, generally have 3～10 groups to get final product.On the inlet of spraying box, ball-cock assembly is installed, also is provided with escape pipe in the side of spraying box, this escape pipe is to adopt a hollow pipe to pass spraying box, and an end of hollow pipe is on the inner liquid level of spraying box, and its other end then leads in the chimney.
When work, the alkali lye of employing sprays, like sodium hydroxide solution, the aqua calcis of 5～40 quality %; After the alkali lye in the spraying box continued to drop to certain position, ball-cock assembly was opened automatically, and the pressure in the input duct reduces at this moment; The non-negative-pressure variable frequency pump is opened; By adding spraying box in the liquid storage tank, after alkali lye added to the relevant position, ball-cock assembly was closed automatically with alkali lye.Alkali lye by the vaporific ejection of shower, gets in the chimney after the hydraulic pump pressurization of spraying box, freely descends, and contacts the XO in the absorption from flue gas with the flue gas gas-liquid of being come up by the chimney below
2Gas like nitrogen dioxide, carbon dioxide, sulfur dioxide etc., falls into the collecting pit of chimney bottom then, turns back in the liquid storage tank through liquid back pipe.The dust or the dirt that absorb settle down in collecting pit, drain into the liquid storage tank bottom earlier by blow-off pipe, and absorption liquid sees through screen pack, and dirt is dammed to get off, and discharge from the sewage draining exit of liquid storage tank.
