The nozzle cooler comprises a first layer nozzle, a second layer nozzle, a third layer nozzle, water sealing, a flue gas inlet, a body, a flue gas outlet and negative pressure water sealing and is characterized in that after the flue is evaporated and cooled, the three-layer nozzle is used for conditioning the dust content, the temperatures and the humidity of the flue gas. The nozzle cooler has the advantages that the cooler not only can simplify the internal structure, is not easily blocked, occupies less land and reduces the artificial cleaning workload but also reduces the energy consumption, improves the cooling effect, saves the water resources and is particularly suitable for the areas poor in water resources.
Description
Technical field
The utility model relates to the cooling cleaner in the flue gases purification fields such as metallurgy, waste gas pollution control and treatment, specifically be a kind of can be in 800～1000 ℃ of high-temperature smokes with three layers of nozzle with lower the temperature three layers of jet nozzle cooler of dedusting of volume of smoke.
Background technology
At present, the numerous and confused dilatation of each steel mill's baby Bessemer converter, the dust pelletizing system ability is obviously not enough, generally all system is put into the melting pot, and investment is big, and is long in time limit, and sewage disposal also will be done corresponding transformation.In addition, the cooling cleaner in the existing flue gases purification adopts the two-stage venturi scrubber that flue gas is lowered the temperature and dedusting more.Wherein, first order Venturi tube equipment resistance is big, the water consumption height, and energy consumption is big, and this just makes traditional two-stage venturi scrubber when lowering the temperature dedusting, and it is big to exist equipment resistance, energy consumption height, shortcoming such as waste water.In the area of water, electric power resource poorness, these shortcomings become the serious restraining factors of enterprise development, environmental protection.
The utility model content
The purpose of this utility model provides a kind of three layers of jet nozzle cooler, is used in the dedusting of lowering the temperature in the converter of newly-built or new transformation, and solves in problems such as first order Venturi tube cooling dedusting stage energy consumption height, water consumption are big.
The utility model has replaced one-level Venturi tube, one-level elbow separator etc., and technological process is: flue gas → cooling → dedusting → discharge flue gas.The nucleus equipment of this flow process is three layers of jet nozzle cooler, and it comprises ground floor nozzle (1), second layer nozzle (2), the 3rd layer of nozzle (3), negative pressure water seal (4), exhanst gas outlet (5), main body (6), water seal (7), smoke inlet (8); Be provided with three layers of nozzle of cooling and dedusting key equipment in the utility model.Its principle is to utilize the ground floor nozzle to improve the atomizing effect of cooling water, makes the flue-gas temperature that enters drop to 75 ℃ rapidly; Utilize the turbid circulating water rapid evaporation heat absorption of second layer nozzle to reduce flue-gas temperature, collect fine dust with the minimum steam atomization water droplet that is exceedingly fast and become big dust, thereby be beneficial to after flue gas contraction gas flow rate slows down, dust carries out sedimentation; Utilize the 3rd layer of nozzle periodic flushing, prevent system jams.Efficiency of dust collection can reach 80%, 65～70 ℃ of exhanst gas outlet temperature.
The connected mode that adopts hydrolock that is connected of the utility model and flue, this connected mode can absorb because the thermal deformation of flue, and the displacement that produces can prevent effectively that flue gas is excessive.
Dischargeable capacity of the present utility model should guarantee that flue gas and water have sufficient time and space to carry out heat, wet exchange, plays the effect of gravity settling chamber simultaneously, and approximately 60%～80% of Dust Capacity meal dirt settles.
Because thereby ground floor nozzle of the present utility model is to spray the absorbing high temp flue gas heat by the spray water that the water of certain pressure, flow and the cavity of Compressed Gas process nozzle mixing accordingly mixing back produce in cooler to cool off, most of water evaporation, thus 35% above quantity of circulating water saved.
Shouting the elimination that mouthful contraction section causes resistance owing to the minimizing of the water yield and because of first order Venturi tube, elbow separator, SR can reduce by 4～6KPa, and the fire door situation of smoldering will be clearly better.Under the certain situation of blower fan, can more effectively carry out resistance and distribute, clean-up effect also makes moderate progress, and the blower fan time between overhauls(TBO) prolongs more than one times.
Reasonable Arrangement nozzle (every layer of nozzle is equally distributed in the horizontal direction) disappears the cooler inner dead space, because gas flow rate is low, the dust-laden water droplet is easy to separate, and the drain water seal that has solved the one-level dehydrator is wrapped up in the problem of band coal gas.
In sum, the utility model can reduce water consumption, and SR is descended, and cuts down the consumption of energy, and reaches remarkable cooling dust removing effects, thereby is beneficial to environmental protection, also helps reducing labor strength.

The specific embodiment
A kind of three layers of jet nozzle cooler comprise ground floor nozzle, second layer nozzle, the 3rd layer of nozzle, water seal, smoke inlet, main body, exhanst gas outlet, negative pressure water seal.Main body is a cylindrical member, and its top arrival end is equipped with water seal, and ground floor nozzle and second layer nozzle, the 3rd layer of nozzle below it are housed in described main body, has negative pressure water seal and exhanst gas outlet in the bottom of main body.Three layers of nozzle evenly distribute in the horizontal direction, spray in main body.
From the flue gas that flue comes out, the smoke inlet of flowing through from top enters, and through water seal, flue gas enters in the main body, and the particulate water smoke of main body ground floor nozzle ejection fully mixes with flue gas, with the water smoke evaporation, high-temperature flue gas is dropped to about 75 ℃ rapidly; Flue gas is collected fine dust and is become big dust through with second layer nozzle ejection turbid circulating water parcel grit then, and the water droplet that contains big dust falls, and discharges from lower body part, and the gas after dedusting is discharged from exhanst gas outlet; The 3rd layer of nozzle periodic flushing prevents system jams.Water seal can absorb the thermal deformation of flue and the displacement that produces, and prevents that effectively flue gas is excessive, and the flue dust that will be attached on the main body inner wall dashes the bottom of falling main body, thereby discharges from lower body part.
The utility model successfully is used in the purifying smoke of steel converter system, and the operational factor of this equipment is: maximum decarbonization rate: 0.45%/min; Smoke inlet temperature: 800～1000 ℃; Exhanst gas outlet temperature: 65～70 ℃; Save the water yield: 35%; Exhanst gas outlet gas content :≤10mg/Nm
