Description

Deodorizing equipment for vertical garbage transfer station

Technical Field

The utility model relates to the technical field of garbage treatment, in particular to deodorizing equipment of a vertical garbage transfer station.

Background

The odor of the garbage is generated by decomposing organic components in the garbage by bacteria, 75-80% of the household garbage is organic matters, and the household garbage mainly comprises pericarps, vegetable leaves, vegetable stems, leftovers/vegetables, skins, hairs, viscera, fat, excrement, offal/blood, leaves, waste paper, flowers, plants, organisms of animals and the like and certain moisture. In the natural digestion process, malodor is generated under the action of aerobic/anaerobic fermentation and the like, and particularly in hot weather, the malodor becomes more serious due to the quickened fermentation. The odor emitted from the garbage stacking place causes great pollution to the air, and also seriously affects the normal life of surrounding residents, and further worsens the environment, so that the deodorizing of garbage becomes necessary.

The deodorizing equipment commonly used at present mainly comprises a negative pressure chemical and spray dedusting deodorizing system, a negative pressure biological and spray dedusting deodorizing system, a high-energy ion deodorizing system and the like. The negative pressure chemical and spray dedusting and deodorizing system is used for regularly spraying plant extraction type deodorant to workshops in the operation process, and the deodorant can wrap odor molecules, so that odor is effectively reduced. The fan that the system was equipped with must install in opening such as the gate in rubbish deposit or screening workshop, can form negative pressure in the workshop like this better, and then effectively restrain the odor overflow, can improve dust removal, deodorization system's purification efficiency by a wide margin. However, the method has poor equipment integration level, and the deodorant is sprayed in a workshop in a large range to bring adverse effects to the work and even the body of workers. In the operation process of the negative pressure biological and spray dedusting and deodorizing system, waste gas is led into a purifying tower, the gas enters the purifying tower and then impacts aqueous solution in the tower to form a gas-liquid mixed water curtain, dust in the waste gas is continuously dissolved in the aqueous solution, and simultaneously, chemical molecules in the solution and malodorous substances react chemically; then, the waste gas can continue to flow upwards to a packing layer of the purifying tower to contact with the packing on the carrier, and the biological bacteria inoculated on the packing are utilized to further decompose odor; finally, the odor is adsorbed by adopting a high-activity activated carbon fiber net and discharged into the atmosphere through a chimney meeting the standard height. However, the biological bacteria adopted by the method have high requirements on environmental temperature and humidity, and the biological bacteria are easy to die, so that the purification efficiency is greatly attenuated; meanwhile, the filter medium is easy to be blocked due to incomplete dust filtration in the purifying tower. In addition, some high-energy ion deodorization systems mainly rely on plasma to decompose and remove odor, and as a single technical means, the treatment effect of the high-energy ion deodorization system is greatly influenced by concentration and fluctuates, and the maintenance cost is high. Therefore, there is a need for an optimized improvement against the drawbacks of the existing deodorizing devices.
