Abstract

The utility model discloses a spray tower hot -blast furnace SOx/NOx control device, including the spray tower to and liquid medicine jar, controller, water pump and spray gun, the spray gun clamps at the spray tower lateral wall, and in the furnace chamber of the directional spray tower of the muzzle of this spray gun, the liquid medicine jar is connected through the pipeline and the end of intaking of water pump, and the play water end (W. E. ) of water pump passes through the pipeline to be connected with the spray gun, and water pump and spray gun are connected with the controller, and the intussuseption of liquid medicine jar is filled with liquid medicine. The utility model discloses an in the spray gun spouted liquid medicine the furnace chamber to the spray tower, the flue gas that produces combustion processes carried out the SOx/NOx control processing, gets rid of sulfur dioxide, nitrogen oxide in the flue gas, makes the steam that discharges in the air accord with national emission standard, has the better feature of environmental protection.

Description

A kind of spray tower hot-blast stove fume desulfuring and denitrifying apparatus
Technical field
The utility model relates to a kind of flue gas desulfurization and denitrification device, the spray tower hot-blast stove fume desulfuring and denitrifying apparatus specifically in a kind of ceramic production workshop.
Background technology
In Production of Ceramics process, need to use spray tower hot-blast stove.Spray tower hot-blast stove uses coal to burn as incendiary material usually, make hot-blast stove in use, because burning can produce a large amount of flue gases, comprise a large amount of sulfur dioxide, oxynitrides in this flue gas, this flue gas is directly discharged in air and can pollutes air ambient.At the society to environmental requirement increasingly stringent, environmental protection is even more important for manufacturing enterprise, and this is the key factor of continuous production and development, therefore, just can be discharged in air after needing to process the flue gas produced in this Combustion of Hot Air Furnace process.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of spray tower hot-blast stove fume desulfuring and denitrifying apparatus, effectively can remove the pernicious gas such as sulfur dioxide, nitrogen oxide in flue gas, improves the feature of environmental protection.
In order to solve the problems of the technologies described above, the utility model takes following technical scheme:
A kind of spray tower hot-blast stove fume desulfuring and denitrifying apparatus, comprise spray tower, also comprise liquid medicine tank, controller, water pump and spray gun, spray gun is installed on spray tower lateral wall, the muzzle of this spray gun points in the furnace chamber of spray tower, and liquid medicine tank is connected with the water inlet end of water pump by pipeline, and the water side of water pump is connected with spray gun by pipeline, water pump is connected with controller with spray gun, is filled with liquid medicine in liquid medicine tank.
In described water pump, also attaching has return duct, and this return duct is connected to liquid medicine jar.
Described spray tower sidewall offers through hole, and the nozzle segment of spray gun inserts in this through hole.
The liquid medicine of filling in described liquid medicine liquid medicine tank is ammoniacal liquor.
Described spray tower outer wall is at least arranged a spray gun.
Liquid medicine is sprayed onto in the furnace chamber of spray tower by spray gun by the utility model, desulphurization denitration process is carried out to the flue gas produced in combustion process, remove the pernicious gas such as sulfur dioxide, nitrogen oxide in flue gas, flue gas is discharged in air after treatment and can not causes larger pollution to air, the gas of discharge meets national environmental standard requirement, realizes the cleaner production of spray tower.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model catenation principle schematic diagram.
Detailed description of the invention
For the ease of the understanding of those skilled in the art, below in conjunction with accompanying drawing, the utility model will be further described.
As shown in Figure 1, the utility model discloses a kind of spray tower hot-blast stove fume desulfuring and denitrifying apparatus, comprise spray tower, liquid medicine tank, controller, water pump and spray gun, spray gun is installed on spray tower lateral wall, and the muzzle of this spray gun points in the furnace chamber of spray tower, and liquid medicine tank is connected with the water inlet end of water pump by pipeline, the water side of water pump is connected with spray gun by pipeline, water pump is connected with controller with spray gun, is filled with liquid medicine in liquid medicine tank, and this liquid medicine is generally ammoniacal liquor.In water pump, also attaching has return duct, and this return duct is connected to liquid medicine jar, and this return duct is generally the rear portion being arranged on water pump, when remaining liquid medicine in water pump, liquid medicine tank Inner eycle can be returned to by this return duct to use, both save resource, the effect preventing booster can be played again.Controller controls water pump and spray gun runs, and realizes conveying and the sprinkling of liquid medicine.
Spray tower sidewall offers through hole, and the nozzle segment of spray gun inserts in this through hole.Spray gun periphery also can arrange corresponding support, and for fixing spray gun, ensure that spray gun can stably be installed, can not easily dropping, it is dangerous to produce.In actual use, because spray tower hot-blast stove is comparatively large, therefore generally all multiple spray gun can be set, to spray liquid medicine in the furnace chamber of spray tower simultaneously, farthest desulphurization denitration be carried out to flue gas.
The volume of liquid medicine tank is comparatively large, generally all reaches the capacity of 2.5 tons.Controller can by manually starting control.Water pump pressurization suction, liquid medicine in liquid medicine tank is extracted out and delivers to spray gun, liquid medicine is sprayed in the furnace chamber of spray tower by spray gun again, react with smoke contacts, remove the toxic gas such as sulfur dioxide, nitrogen oxide contained in flue gas, the content making flue gas enter the sulfur dioxide of the water vapour in air can reduce, and oxynitrides content can reduce, avoid causing excessive pollution to air, improve the feature of environmental protection.
It should be noted that, the above is not the restriction to technical solutions of the utility model, and under the prerequisite not departing from creation design of the present utility model, any apparent replacement is all within protection domain of the present utility model.
