Description
Technical field
The invention belongs to atmosphere polluting controling technology field, and in particular to a kind of alkaline pollution gas cleaning plant.
Background technology
With the quickening of Chinese Industrialization process, Environment Pollution Event emerges in an endless stream.At present, In The Atmosphere Over China pollution situation ten
Divide seriously, common alkaline pollution gas is mainly ammonia and other organic basic gases in air(Organic amine, as diethylamine,
Diethylenetriamine, triethylene tetramine etc.), these alkaline pollution gases are primarily present in the industries such as chemical industry, casting, printing and cultivation
In.
At present, the purified treatment of alkaline pollution gas mainly uses spray column, its function mode is:Constantly by alkaline pollution
Gas is introduced by air hose from bottom of towe, and alkaline pollution gas is in uphill process, with carrying out gas-liquid two-phase from tower top spray is lower
Come into full contact with, while occur to absorb neutralization reaction, after alkaline pollution gas is purified, then by wind turbine after demisting plate dehydrating demisting
It is discharged into air.Fall into bottom of towe acid absorbing liquid can after water pump is pressurized again from tower top spray and under, so as to fulfill multiple
Recycle.But to reach stringent discharge standard, many enterprises need to use side of the multi-stage spray tower by multi-stage spray
Formula realizes removal to the harmful substance such as suspended particulate substance and alkaline pollution gas, this mode there are the drawbacks of be multi-stage spray
Mode not only needs consumption to build multilevel device, and equipment, which is taken up an area, to be increased, while also expends substantial amounts of absorbing liquid and water.In purification process
In, the booster pump of spray column needs to run always in order to which absorbing liquid supercharging is recycled to tower top, cause its there are the drawbacks of one
It is that single purification efficiency is low, second, energy consumption is higher.In order to effectively control the pollution of alkaline pollution gas, it is dirty preferably to reduce alkalescence
The discharge of gas is contaminated, there is an urgent need for good purification, alkaline pollution gas cleaning plant of low cost.
The content of the invention
Present invention aims to overcome that prior art defect, there is provided a kind of alkaline pollution gas cleaning plant, the device are net
It is good and of low cost to change effect.
To achieve the above object, the present invention adopts the following technical scheme that:
A kind of alkaline pollution gas cleaning plant, it includes the purifying box that top is equipped with air inlet equipped with gas outlet, lower part, described
Adsorption cleaning unit is equipped with purifying box, the adsorption cleaning unit includes the support plate being horizontally located in purifying box, described
Some ventholes are offered in support plate, the top opening of the filter bag and filter bag to filter gas is equipped with each venthole
Set;The gas outlet is higher than the height on filter bag top in the height of vertical direction.
Specifically, the filter bag is made of ion exchange fiber material, the cross section of filter bag can be circular, ellipse or
Polygon(Such as triangle, square)Deng.The connection of venthole and filter bag can use the ordinary skill in the art, can such as incite somebody to action
Turn up and paved in venthole outer at the top of filter bag, by bolt by both be fixedly connected or venthole at be equipped with and upwards prolong
The venting channels stretched, top and the venting channels of filter bag are fastenedly connected.
Further, the ion-exchange fibre refers to containing a kind of or more in mono carboxylic, double carboxyls and sulfonate functional groups
Kind conjugate fiber.
It is further preferred that above-mentioned alkaline pollution gas cleaning plant further includes regenerative system, the regenerative system includes
Regeneration pipeline, the regeneration pump in regeneration pipeline and the actified solution loaded on purifying box bottom, the one of the regeneration pipeline
End is connected with actified solution, and the other end of regeneration pipeline stretches into the top in purifying box, and stretches into purifying box internal upper part again
Raw pipe ends are provided with some nozzles, and the quantity of nozzle is consistent with the quantity of filter bag, and nozzle stretches into filter bag top.
Specifically, the actified solution can be one or more mixing in dust technology, dilute hydrochloric acid, dilute sulfuric acid and phosphoric acid,diluted
Liquid.
Specifically, the nozzle material is stainless steel or plastics etc., there is preferable corrosion resistance.
It is further preferred that the purifying box side wall is provided with liquid level gauge and acidometer, regenerated to monitor in purifying box
The liquid level of solution and the pH of actified solution.
It is further preferred that be provided with air flap in the purifying box, air flap inclined upward to the right, air flap
Top is fixedly connected with purifying box side wall and air flap top is higher than air inlet in the height of vertical direction, and air flap bottom is leaned on
The liquid level of nearly actified solution.
It is further preferred that horizontally extending strainer is equipped with below the filter bag, in polluted gas intake process
In, preliminary uniform air distribution can be played the role of, can prevent it from falling directly into actified solution when filter bag is come off using the long period.
Alkaline pollution gas cleaning plant of the present invention, using the filter material in adsorption cleaning unit to entering the alkali in purifying box
Contact scar gas is come into full contact with purifying box, trickle by the dust in the principle capture polluted gas of chemisorbed etc.
The alkalescence pernicious gas such as particle and ammonia, polyamines, so as to fulfill the purification to polluted gas.Details are as follows for concrete principle:
Adsorption reaction:NH3 + R-COOH → R-COONH4
NH3 + R-SO4H → R-SO4NH4
Regenerative response:R-COONH4 + H+ →R-COOH + NH4 +
R-SO4NH4 + H+ →R-SO4H + NH4 +
The chemical reaction occurred in above process, is acid-base neutralization reaction in adsorption process, and regenerative process is prepared by strong acid

Change, when alkaline pollution gas passes through filter bag, react with mono carboxylic, double carboxyls and sulfonate functional groups, so as to fulfill right
The removal of alkaline pollution gas, good purification(Purification efficiency is more than 95%).With the existing phase by the way of spray column purification
Compare, to purify the made filter bag reaction contact area bigger of the ion-exchange fibre of alkaline pollution gas in apparatus of the present invention,
Reactivity strengthens, and purification efficiency significantly improves.
2)Regenerative system in apparatus of the present invention can realize the regeneration of filter bag and recycle, of low cost, used
Ion-exchange fibre has certain saturated extent of adsorption, before the absorption of not up to saturation, possesses adsorption capacity always, without opening
Open regenerative system;When reaching saturation absorption, start regenerative system, the alkali for ion-exchange fibre being adsorbed using actified solution
Contact scar gas component elute, fibers adsorption ability recover, can be repeatedly circulated, reduce overall use into
This;For regeneration pump compared with spray column pumps, present apparatus pump is intermittent operation, and spray column pump is continuous operation, and Same Efficieney declines
Low run time, correspondingly reduces energy consumption.
3)The present invention can effectively capture the alkaline pollution gas entered from air inlet in advance by the air flap of setting
In fine particle, dust etc., improve clean-up effect.In addition, apparatus of the present invention are simple in structure, easy to operate, cost is relatively low,
It is adapted to industrialized production, great application value.
