Description

Recycle chemicals dosing plant

Technical field

The utility model is related to pacify ring field more particularly to a kind of cycle chemicals dosing plant for handling exhaust gas.

Background technology

In the actual production process, need to use the poisonous fume of potassium permanganate spray process reproducibility（Such as H₂S）, by It is not high in potassium permanganate solubility, it needs that potassium permanganate solid frequently is added into spray liquid.And the permanganic acid being newly added Potassium solid dissolution is slower, cannot meet continuous use and require.Potassium permanganate is persistently supplemented even by automatic medicine adding apparatus Rich solution, and need the potassium permanganate lean solution continued emissions in circulating slot to waste water processing station, in this way, waste water processing station will be handled A large amount of waste water, operation cost are very high.

Therefore, it is necessary to design a kind of new device to solve the above technical problems.

Utility model content

The purpose of the utility model is to overcome above-mentioned technical problems, propose a kind of cycle chemicals dosing plant.

To realize foregoing purpose, the utility model adopts the following technical solution：A kind of cycle chemicals dosing plant comprising pass through The sequentially connected liquid pool of pipeline, a first filter, a diaphragm pump, a circulating slot, a circulating pump, a spray column form the One access, the spray column are mounted on above circulating pump, and pipeline connection one second is also relied between the liquid pool and circulating slot Filter forms alternate path, and first access and alternate path form a circulation path, opened on the side wall of the spray column Equipped with an air inlet, the top of the spray column opens up a gas outlet, and one for ejecting liquid is additionally provided in the spray column Nozzle.

As a further improvement of the utility model, a dosing mouth is opened up on the liquid pool.

As a further improvement of the utility model, a filler is opened up on the liquid pool.

As a further improvement of the utility model, the cycle chemicals dosing plant further include an agitating paddle and give agitating paddle The stirring motor of power is provided, the agitating paddle is installed in liquid pool.

The spray column is packed tower or sieve-plate tower as a further improvement of the utility model,.

Using this cycle chemicals dosing plant, used lean solution can be returned to the rich solution that dosing is configured to again, be delivered to Spray column recycles, and has not only recycled the useful composition in lean solution, while reducing the generation of a large amount of waste water, had both saved Wastewater treatment expense also reduces pollution.

Description of the drawings

Fig. 1 is the overall structure diagram for the embodiment that the utility model recycles chemicals dosing plant.

Specific implementation mode

Technical solution is clearly and completely described below in conjunction with the utility model embodiment, it is clear that described Embodiment is only the utility model a part of the embodiment, instead of all the embodiments.Based on the implementation in the utility model Example, every other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to The range of the utility model protection.

Referring to Fig. 1, a kind of cycle chemicals dosing plant 100 comprising by a 160 sequentially connected liquid pool 110 of pipeline, One first filter 120, a diaphragm pump 130, a circulating slot 140, a circulating pump 150, a spray column 180 form the first access, Spray column 180 is mounted on 150 top of circulating pump, and the connection of pipeline 160 one second is also relied between liquid pool 110 and circulating slot 140 Filter 170 forms alternate path, and the first access and alternate path form a circulation path, opened up on the side wall of spray column 180 There are an air inlet 181, the top of spray column 180 to open up a gas outlet 182, be additionally provided with for ejecting liquid in spray column 180 One nozzle 183.

In some embodiments of the utility model, a dosing mouth 111 is opened up on liquid pool 110.

In some embodiments of the utility model, a filler 112 is opened up on liquid pool 110.

In some embodiments of the utility model, cycle chemicals dosing plant 100 further include an agitating paddle 113 and to stirring Paddle 113 provides the stirring motor 114 of power, and the agitating paddle 113 is installed in liquid pool 110.Agitating paddle 113, stirring motor 114 for accelerating the solution rate of medicament in a solvent.

In some embodiments of the utility model, spray column 180 is packed tower or sieve-plate tower.In other embodiments, The tower of spray column 180 or other forms.

It is provided with several control valves on each pipeline 160, controls the flow velocity of liquid.

Cycle chemicals dosing plant 100 operational process be：The present embodiment is added by medicament of potassium permanganate in liquid pool 110 In solvent-water, stirring motor 114 drives agitating paddle 113 to rotate, and potassium permanganate is dissolved in the water to form rich solution, and rich solution is through pipeline 160, which flow through the first access, reaches spray column 180, including H₂The poisonous fume of S is entered by air inlet 181 in spray column 180, rich Liquid is sprayed by nozzle 183, rich solution and H₂S contact simultaneously absorbs H₂S, after chemical reaction, rich solution becomes lean solution, toxic useless H in gas₂S is removed that become can be with the tail gas of qualified discharge, and spray column 180 is discharged by gas outlet 182 in tail gas, and lean solution is logical Cross alternate path and be back to liquid pool 110, then add Permanganate into liquid pool 110, lean solution becomes rich solution, cycle after It is continuous.

Using this cycle chemicals dosing plant 100, used lean solution can be returned to the rich solution that dosing is configured to again, conveying It is recycled to spray column 180, has not only recycled the useful composition in lean solution, while reducing the generation of a large amount of waste water, Both wastewater treatment expense had been saved, pollution is also reduced.

Although being example purpose, preferred embodiments of the present invention, the common skill of this field are had been disclosed for Art personnel will realize the situation of the scope of the utility model and spirit disclosed in not departing from by appended claims Under, various improvements, additions and substitutions are possible.
