Waste gas purification tower

Waste gas purification tower is a kind of two phase reverse flow packing absorption tower, it is a two phase reverse flow packing absorption tower. When acid gases from below the tower body inlet along the tangential enters the purification tower, under the influence of the power of fan, quickly filled with inlet section of space, and then evenly through flow up to the first level packing absorption section. On the surface of packing, gas phase acid substances and alkaline substances in the liquid phase reaction, reaction substance soluble acids (mostly) with the absorption liquid flows into the lower reservoir. Incomplete absorption of acid gases continue to rise into the first level spray section. Closed and liquid in the spray section from the uniform of the high-speed nozzle, forming numerous tiny droplets, contact with the gas well blended, continue to learn reaction occurs, and acid gases rise to secondary packing section, spray is similar to the first level of the absorption process. Secondary and primary nozzle density is different, different spray pressure, acidic gas absorption concentration range is also different. In the spray process of two phase contact and packing paragraphs is also a process of heat and mass transfer. By controlling the superficial velocity and the retention time to ensure the sufficient and stability of the process. Tower body mist, is the most upper clip in gas absorption liquid droplets are cleared down here, after processing, the clean air from the top exhaust purification tower into the atmosphere.

1, the application scope is as follows: can be widely used in chemical industry, light industry, printing and dyeing, medicine, steel, machinery, electronics, instrumentation, electroplating and other industrial sector emissions in the process of production, such as nitric acid, hydrofluoric acid tail gas and sulfur oxides (SOx), nitrogen oxide (NOx), carbon oxide compound acid gases (CO, CO2), etc.

2, high purification efficiency; SST series purification tower adopts secondary reverse spray, packing specific surface area is big, be determined by the experimental study of gas liquid ratio to ensure the stable performance, for a variety of the concentration of acid gas purification efficiency can reach 85% 95%.

3, this product equipment low resistance on the basis of ensure enough gas liquid contact area, day qing choose air purification tower dynamic force characteristics of the best packing varieties and structure form, make the equipment under rated air flow resistance is not more than 40 mm water column, domestic all kinds of stuffing absorbing tower is one of the lowest drag. It is highly advantageous for with corrosion resistant low pressure ventilator.

4, cover an area of an area small; Purification tower the tower body, the absorption liquid tank, circulating pump, absorbing liquid pipeline system combined into a complete set of equipment, compact structure, convenient for installation and operation management, cover an area of an area small, adaptable, no matter for new construction or technological upgrading projects.

1, should first check when using purification tower equipment each system pipeline valves are in good condition, absorbing liquid reagent selection and matching is correct, the absorption liquid can not meet the specified requirements, the need to supplement in time. Should open water pump 3-5 minutes when the phone is switched on After the bell and open fan. When closing the purification system, should turn off the fan 2-3 minutes and then close the water pump, can't disorderly open, otherwise it will burn out motor, block fillers, affect the purification effect.

2, for purification tower fan and water pump connection can't literally touch, should be absolutely sure they turned to the right, shall not be reversed, otherwise it will damage the motor, and can cause an accident.

3, when after delivery of equipment operation, the use of units should be sent to use special custody, regular inspection, found that equipment abnormal sound or leaking, should stop to repair the rear can use.

4, equipment installed in the outdoor, pumps shall be made for the fan motor cover, so as not to be affected with damp be affected with damp. Equipment whether Ann Indoor and outdoor, such as selection of glass or plastic fan, must install shield, in case of screw loosening, bearing failure or sucked into sundry, destroyed impeller and wounded personnel, cause an accident.

5, cleaning fluid replacement and with: I plant uptake of purifying liquid ratio of formula is according to different user unit of gas source, the concentration of high and low to decide, upon the acceptance of the equipment debugging normal will provide account specific user manager.
