Preparation method of plant extracting solution deodorant

Abstract

The invention discloses a preparation method of a plant extracting solution deodorant. The deodorant uses Chinese herbal medicine as raw materials, a volatile oil extractor is adopted for extraction to obtain water extracting solution and volatile oil, the water extracting solution is subjected to separation and refining processes to obtain water extracts, then, the water extracts, the volatile oil, de-ionized water and essence are mixed for emulsification, and finally, the plant extracting solution deodorant disclosed by the invention is prepared through filtering. The plant extracting solution deodorant disclosed by the invention has the characteristics that the use is safe and convenient, the environmental-friendly effect, no toxicity and no harm are realized, through field experiment detection in a garbage transfer station, the ammonia gas removal rate can reach about 63 percent, the odor concentration inside and outside the garbage transfer station after deodorization can be much lower than the national standard, the peripheral air quality and the work condition in the garbage transfer station are greatly improved, in addition, the use cost of the deodorant is very low, and the deodorant is suitable for being used for deodorization in the garbage transfer station of urban communities.

Description

technical field [0001] The invention relates to a preparation method of a deodorant used in a municipal solid waste transfer station, in particular to a preparation method of a plant extract deodorant. Background technique [0002] With the rapid economic development and the acceleration of the urbanization process, the output of municipal solid waste continues to increase. In 2008, the volume of municipal solid waste removal in my country was 154 million tons. At present, the main treatment method of domestic waste in large and medium-sized cities in my country is to transport the collected waste to a waste transfer station, and then transfer it to landfills and other places after compression. In the process of garbage collection, dumping, compression and transshipment, unpleasant odors are produced due to natural decay and bacterial reproduction, which cause a lot of pollution to the smelly places in closed spaces such as garbage transfer stations and their surrounding env...

Problems solved by technology

However, the problems of biological deodorization are as follows: (1) During the operation, it is difficult to determine the cell concentration and biofilm thickness; (2) The reaction speed and saturation factor are all measured under suspension conditions, while the Compared with the suspension, the reaction speed and saturation factor are quite different; (3) the assumed liquid phase mass transfer is not the rate-limiting step, which is reasonable for gases with relatively high solubility, but for some insoluble gases such as hydrocarbons The error is relatively large; (4) The selection, domestication and construction technology of high-efficiency deodorizing bacteria is still immature; (5) The research on the treatment of high concentration and mixed odor is not enough, and the application environment is greatly restricted

However, the main "deodorization" mechanism of most plant extract deodorants on the market is still the masking effect of spices, while the deodorization effect of plant active ingredients is not very obvious, and its removal efficiency for odor molecules is not very high, such as The removal efficiency of ammonia is generally less than 50%, and the cost of use is relatively high
