Kitchen waste odor removal process

Abstract

The invention relates to the field of kitchen waste treatment, in particular to a kitchen waste odor removal process which comprises the following steps: S1, odor collection: collecting various odors through a front-end collection system, and collecting the odors into a collection box; s2, acid spraying: introducing the odor in the collecting box into an acid spraying mechanism for acid spraying, and enabling spraying liquid to be in full contact with the odor through the acid spraying mechanism, so that components in a gas phase are transferred to a liquid phase and are subjected to neutralization, oxidation or other chemical reactions with the odor; s3, alkali spraying: introducing the odor subjected to acid spraying into an alkali spraying mechanism for alkali spraying, and enabling spraying liquid to be in full contact with the odor through the alkali spraying mechanism; by improving the acid spraying mechanism and the alkali spraying mechanism, gas-liquid mixing is fully realized in the acid spraying process and the alkali spraying process, so that the gas-liquid mixing is sufficient, and the efficient deodorization effect is further achieved.

Description

technical field [0001] The invention relates to the field of kitchen waste treatment, in particular to a process for removing the odor of kitchen waste. Background technique [0002] Food waste will produce odor during unloading and processing. The odor is not only unbearable, but also contains a variety of toxic substances, which cause great harm to human health and the environment. In the prior art, there is a process for treating the odor of kitchen waste. For example, the invention patent with application number CN202110197251.3 discloses a combined device and process for the treatment of kitchen waste waste gas, which discloses a first-level spray tower and a The secondary spray tower, the primary spray tower and the secondary spray tower are simply circulated and sprayed through a simple circulating water tank and a spray mechanism to realize the mixing of odor and liquid, and then make the odor in the odor. The molecules and the liquid undergo neutralization, oxidati...

Problems solved by technology

[0002] Food waste will produce bad smell in every link of unloading and processing. The bad smell is not only unbearable, but also mixed with a variety of toxic substances, which will cause great harm to human health and the environment. In the prior art, there is a process for treating the odor of food waste. For example, in the invention patent of application number CN202110197251.3, a combined device for treating food waste gas and its process are disclosed. It discloses a first-stage spray tower and The second-level spray tower, the first-level spray tower and the second-level spray tower only perform simple circular spraying through a simple circulating water tank and a spraying mechanism to realize the mixing of odor and liquid, thereby making the odor in the odor The molecules and the liquid undergo neutralization, oxidation or other chemical reactions to remove the substances in the odor. The more fully the contact between the odor and the spray liquid, the better the effect of the reaction between the two, and the best deodorizing effect, but the invention It is obvious that the odor is sprayed after being pumped into the first-level spray tower or the second-level spray tower. This spray mixing process is just that the odor is sprayed and mixed during the process of rising from the spray tower, and then it is sprayed and mixed. The pressure mechanism is sent to the lower-level processing mechanism for processing, so the gas-liquid contact between the odor and the spray liquid is very limited in this process, coupled with the adsorption of the odor by the negative pressure mechanism, resulting in gas-liquid contact The time is very short, so it can be seen that the gas-liquid mixing is very insufficient. It is conceivable that the effect of deodorization is also very poor. In many cases, it is doing useless work. The acid spray and alkali in the prior art Spraying is basically the same as the situation in the invention patent with application number CN202110197251.3. It is useless, the effect of gas-liquid mixing is extremely poor, and the effect of deodorization is also very poor, resulting in the final deodorization of kitchen waste very bad effect
