Description

White defogging device of organic waste gas spray column

Technical Field

The utility model belongs to the technical field of waste gas treatment, and particularly relates to a white and mist eliminating device of an organic waste gas spray tower.

Background

The existing waste gas tower adopts an alkali adding spray treatment process, and heat is generated by chemical reaction in the neutralization process of alkali liquor sprayed and acid waste gas acid base, so that the temperature difference is caused between the inside of the waste gas tower and the outside. When the temperature of the external environment is low in winter, water vapor in the gas exhausted by the chimney after being neutralized and absorbed by the spray tower is atomized into small water drops to form white fog when meeting cold. Resulting in a visually significant amount of white smoke at the exhaust tower discharge.

In carrying out the utility model, the inventors have found that the prior art has at least the following problems:

at present, most of acid-base waste gas towers in the industry are secondary spray tower processes. The spray tower is divided into a filling area, a spray system and the like. The organic waste gas treated by the spray tower is dissolved in water, and the harmful substances in the waste gas are absorbed under the action of adding acid solution into the water. Wherein the external drug adding device can be an acidic solution or an alkaline solution. The prior art has the technical scheme that the two-stage spraying is formed by serially connecting front and rear spray towers, or the three-stage spraying is formed by serially connecting three spray towers, and then the three spray towers are exhausted to a discharge port through a fan. The process can ensure that the waste gas is fully treated, and the waste gas is treated by two or three sections of spray towers. However, after the process waste gas is neutralized by a plurality of sections of spray towers, if the dehumidification effect is poor, a large amount of water vapor or saturated humidity gas can be entrained and discharged through a discharge port, when the external temperature is reduced, the effect of relatively containing the water vapor in the towers is also reduced, and the water vapor caused by the temperature difference is discharged along with a fan and is condensed and atomized with cold air. Causing white smoke of several meters at the discharge opening.
