Shower towers, also known as spray purification towers, are cost-effective purification equipment commonly used in exhaust gas treatment projects. Spray tower generally have vertical spray tower horizontal spray tower two forms. Shower tower as a new type of spray absorption equipment has been commonly used in the exhaust gas pollution. It will carry out the concept of sulfide bed to the vapor-liquid mass transfer equipment, so that the filler in the spray tower is in the form of fluidization, so that the mass transfer process can be lost to strengthen. Spray tower on a variety of corrosive gas pollution disposal effect is clear, can effectively remove hydrogen chloride gas (HCl), hydrogen fluoride gas (HF), ammonia (NH3), sulfuric acid mist (H2SO4), chromic acid mist (CrO3), cyanuric acid gas (HCN), alkali vapors (NaOH), formalin (HCHO) other water-soluble gases. Spray tower has high pollution efficiency, complex operation management, long service life, the acid alkali waste gas emission after pollution disposal reaches the national emission standard, which is widely used in chemical industry, electroplating, hardware, aluminum, electrical appliances, medicine, printing dyeing, machining other industries. The following Ding Sheng spray tower for different circumstances of waste gas treatment.

First, Ding Sheng spraying tower for different cases of waste gas treatment methods

1、Inert gas treatment

Although inert gases are dangerous, a large amount of inert gases will accumulate, which will reduce the oxygen content around suffocate people.

(1) Discharge the gas in an appropriate place outdoors.

(2) If the cylinder instrument is indoors, connect the exhaust pipe to the outside discharge it slowly.

2、Handling of combustion gases

(1) Adhesion in the container valve the use of appliances on the powder. Oil. Grease easy substances should be cleaned before handling gas.

(2) is strictly prohibited in the same place near the treatment of gas combustible gases to prevent explosions.

(3) Combustion of auxiliary gas treatment should be around the ignition source. No burning explosive substances.

3、Processing of combustible gases

(1) flammable gas emissions. If the emissions are very large, try to choose a place there are few people, pay attention to the surrounding disaster, have the appropriate fire extinguishers, sand water.

(2) When discharging flammable gases into gas cylinders, workers should stand on the side of the outlet to prevent gas injection injury.

(3) When combustion methods are used, pressure reducing valves should be installed to control the velocity of the combustible gas the gas should be released as slowly as possible to burn completely in the combustion unit.

4、Toxic gas treatment

(1) When dealing with toxic gases, workers must wear protective masks, gloves other labor protection equipment as well as personnel who have nothing to do with the treatment work, prohibited entering the gas treatment area.

(2) Absorbents adsorbents used in the treatment of toxic gases should be used before ensuring their effectiveness.

The working principle performance of Ding Sheng spray tower

Shower tower is a kind of equipment for waste gas treatment, such purification equipment can be used in industrial waste gas treatment. Spray tower in the treatment of industrial waste gas is through the wind group will be collected into the waste gas washing tower, flow through the filling layer section (gas / liquid contact reaction of the media), so that the waste gas filling the surface of the flow of liquid (washing liquid) full contact, in order to adsorption of waste gas contained in the acidic alkaline dirt, then clean gas the separation of polluted liquids, to achieve the purpose of clean air.

In the acidic alkaline acid mist exhaust gas, built-in Lassie ball packing, gas-liquid contact surface area; when the exhaust gas through the inlet distribution board, the gas will be evenly distributed in the multi-faceted hollow ball, each point contact, arranged in a “W” route to avoid the phenomenon of bias flow, with the tornado non-obstructive nozzles, 120 ° spraying, so that the gas-liquid mixing efficiency of 90-95%. The gas-liquid mixing efficiency is 90-95%, the clean effect is achieved through the atomized spraying washing of the countercurrent absorbing liquid, which can remove the harmful gases in the waste gas. Alkali spray tower has a two-stage spray device, this design can make the liquid phase to gas phase absorption efficiency to achieve a more optimized, while the gas resistance is too large. Usually the pressure drop is ≤100Pa, so as to achieve high efficiency purification effect.

Precautions for the use of Ding Sheng spraying tower

1, the adjustment of circulating water volume: the water supply pump of the spray tower will decide, when running a boiler can open one, when two three units are running at the same time in winter, the two pumps will be opened all the time, the flow rate of the slurry pump should be adjusted according to the flow rate of the circulating pump, so as to make it equal.

2, the amount of dosing in the shower tower dosing pool: when running a boiler, add 2 bags of alkali, add 5 bags of quicklime, such as winter operation of two three, according to the corresponding multiplier to increase the amount of drugs, so on.

3, the spray tower sedimentation tank should be cleaned frequently, one week in summer to clean up once, three days in winter to clean up once.

4, gray water separator sewage, discharge once per shift, to open the sewage valve, until there is clear water excluded.

5, the above rotating parts should be frequently checked, oiling, found faults should be promptly eliminated, so as to ensure the effect of desulfurization of the spray tower.

6, in the upper lower staircase dosing should pay attention to the foot, to have independent security, mutual security consciousness.

7, the work is completed in a timely manner to clean up the health, so that people away the site clear.
