It includes cooling tower tower body, caustic soda thinning tank and caustic soda transfer pump, the cooling tower tower body is equipped with into mouth, exhaust port, sprays the mechanism, advances the mouth and burn burning furnace to be linked together, and the exhaust port is linked together with the sack cleaner, and spray the mechanism and be connected with cooling water, compressed air, sweep the air through supply line, caustic soda thinning tank inserts the cooling water and sprays the supply line between the mechanism through the caustic soda transfer pump. Through the soda bath after insert diluting among the supply line at the cooling tower cooling water, soda bath and cooling water mix and leading -inly spray the mechanism, and dusts removal of not only can lowering the temperature in can also and the acid gas in the flue gas, lightens the burden of follow -up sweetener, cooling tower and follow -up sweetener sharing caustic soda thinning tank need not add in addition, have only increased a small amount of equipment such as caustic soda transfer pump and flowmeter, and the repacking is simple, and is with low costs.
Description
Technical field
This utility model relates to a kind of temperature-reducing tower removing sour gas, belongs to temperature-reducing tower field.
Background technology
In the flue gas produced in Refuse Incineration Process, containing substantial amounts of pollutant, as particulate matter, sour gas, two
English, heavy metal etc., these materials have harm in various degree to environment.Therefore, the flue gas produced in burning process enters greatly
Before gas, it is necessary to carry out purified treatment, make up to discharge standard.Efficient flue gas purification system is to prevent garbage burning factory two
The key of secondary pollution.
At present, the cigarette temperature in incinerator exit is general at about 200-220 DEG C, and from temperature-reducing tower top, smoke inlet is led through flue
Stream plate enters in temperature-reducing tower, simultaneously enters the spraying mechanism at temperature-reducing tower top through cooling water and the compressed air of water pump boosting, cold
But water is atomized into numerous fine droplet, drop and flue gas uniform contact, vaporization, absorbs the heat of flue gas, reaches cooling-down effect,
Flue gas stream changes direction discharge simultaneously, makes a part of flying dust deposit.Cigarette temperature about 165 DEG C, cigarette after temperature-reducing tower desuperheat
The gas exhaust opening from temperature-reducing tower bottom is discharged, and enters dedusting in sack cleaner, will be carried out by follow-up desulphurization plant afterwards
Deacidification processes.Shortcoming is, such flow process is excessive to the load of follow-up desulphurization plant, and temperature-reducing tower is only responsible for cooling dedusting, does not has
There is desulfurizing function.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of temperature-reducing tower removing sour gas, and it solves
The problem that current temperature-reducing tower does not possess removing sour gas function.
Technical problem to be solved in the utility model takes techniques below scheme to realize:
A kind of temperature-reducing tower removing sour gas, it includes temperature-reducing tower tower body, Caustic soda thinning tank and Caustic soda transfer pump, described
Temperature-reducing tower tower body is provided with smoke inlet, exhaust opening, spraying mechanism, and smoke inlet is connected with incinerator, exhaust opening and sack cleaner
Being connected, spraying mechanism is connected by supply line cooling water, compressed air, purging air, and described Caustic soda thinning tank passes through
Caustic soda transfer pump accesses the supply line between cooling water and spraying mechanism.
As preferred embodiment, described Caustic soda thinning tank and cooling aqueous phase supply line even is provided with effusion meter.
As preferred embodiment, described Caustic soda thinning tank is connected to demineralized water and Caustic soda stock solution by supply line respectively.
The beneficial effects of the utility model are: by the Caustic soda after accessing dilution in the supply line of temperature-reducing tower cooling water
Solution, soda bath mixes importing spraying mechanism with cooling water, is possible not only to dedusting of lowering the temperature, additionally it is possible to neutralize the acidity in flue gas
Gas, alleviates the burden of follow-up desulphurization plant；Temperature-reducing tower and follow-up desulphurization plant share Caustic soda thinning tank, need not additionally add,
Merely add a small amount of equipment such as Caustic soda transfer pump and effusion meter, repacking is simple, low cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
In order to technological means of the present utility model, creation characteristic, reach purpose and be easy to understand with effect, knot below
Conjunction is specifically illustrating, and this utility model is expanded on further.
As it is shown in figure 1, a kind of temperature-reducing tower removing sour gas, it includes temperature-reducing tower tower body, Caustic soda thinning tank and Caustic soda
Transfer pump, temperature-reducing tower tower body is provided with smoke inlet, exhaust opening, spraying mechanism, and smoke inlet is connected with incinerator, exhaust opening and cloth bag
Cleaner unit is connected, and spraying mechanism is connected by supply line cooling water, compressed air, purging air, and Caustic soda thinning tank leads to
Cross Caustic soda transfer pump and access the supply line between cooling water and spraying mechanism.Caustic soda thinning tank and cooling aqueous phase supply pipe even
Effusion meter is installed on road.Caustic soda thinning tank is connected to demineralized water and Caustic soda stock solution by supply line respectively.
Demineralized water and Caustic soda stock solution are made into 10% soda bath in Caustic soda thinning tank, and Caustic soda transfer pump is from Caustic soda thinning tank
Pumping out soda bath, soda bath mixes in supply line with cooling water, and the cigarette temperature in incinerator exit is general at 200-220
About DEG C, entering in temperature-reducing tower from temperature-reducing tower top smoke inlet, mixed cooling water and compressed air simultaneously enter temperature-reducing tower
The spraying mechanism at top, cooling water is atomized into numerous fine droplet, drop and flue gas uniform contact, vaporization, absorbs flue gas
Heat, reaches cooling-down effect；Discharge simultaneously because flue gas stream changes direction, make a part of flying dust deposit, reach dedusting effect
Really；Additionally, soda bath and cooling water are mixed into alkalescence cooling water, by observing flow meter and controlling the output of Caustic soda transfer pump
Flow, regulates the acid-base value of alkalescence cooling water, makes alkalescence cooling water PH be maintained at 9-9.5, and alkalescence cooling water can be with flue gas
In sour gas neutralize, reach remove sour gas purpose, alleviate the pressure of follow-up desulphurization plant simultaneously.Purging air
Can use inside steam blowing temperature-reducing tower, be allowed to keep cleaning.Temperature-reducing tower and follow-up desulphurization plant share Caustic soda thinning tank, no
With additionally adding, merely add a small amount of equipment such as Caustic soda transfer pump and effusion meter, repacking is simple, low cost.
Of the present utility model ultimate principle and principal character and of the present utility model advantage have more than been shown and described.One's own profession
Skilled person will appreciate that of industry, this utility model is not restricted to the described embodiments, without departing from this utility model spirit and
