Description

Detailed Description of the Invention

The present invention relates to livestock manure, agricultural and forestry waste, food processing, using soot gas containing organic acid gas generated in a carbonization furnace that produces wood charcoal in a state of supplying oxygen with a small amount of wood biomass such as rice husk, wood chips, wood chips, etc. After neutralizing and masking malodorous gases such as ammonia gas generated from the compost fermenter in the composting house where the residue is composted, the air in the composting house is adsorbed on the fine branch leaves and then microbial decomposition is performed. The present invention proposes a composting deodorization apparatus for deodorizing residual malodorous gas in a composting house and a method for deodorizing the same.

Conventional deodorizing methods for malodorous gases in compost houses include a water washing method, an adsorption method, a biological deodorizing method, and a combined method. The water washing method is a method of deodorizing by dissolving bad odor gas in water, and there are a spray method and a water tank method. This washing method has a problem in that wastewater treatment costs for water in which malodorous gases are dissolved are required. The adsorption method is a method of deodorizing by adsorbing malodorous gas to sawdust, rice husk and the like. This adsorption method has a problem that the deodorizing effect cannot be maintained when the adsorption amount reaches saturation because sawdust and rice husk adsorbing malodorous gas are dried.

The biological deodorization method is a method in which malodorous gas is dissolved or adsorbed in rock wool or the like where microorganisms live, and deodorized by the action of microorganisms living in the rock wool. This biological deodorization method has a problem in that since rock wool cannot be a nutrient source for microorganisms, microorganisms feel stress due to fluctuations in the load of malodorous gases and cannot perform stable deodorization. The compound system is a system that deodorizes the bad odor after the chemical treatment is performed on the sealed compost house, and a method that adsorbs and deodorizes the malodor after the chemical treatment. This combined system has a problem in that it requires a chemical cost for chemically deodorizing malodorous gas, and in addition, a power charge for the blower due to an increase in pressure loss due to soil deodorization.

The above-mentioned existing deodorizing methods for malodorous gases have been used in livestock houses and compost houses, but there is a problem that the deodorization facility costs and maintenance costs are incurred, putting pressure on livestock management.
Livestock farmers have troubles with odor pollution of livestock facilities that are continually in harmony with local residents, and have reached the mental and physical limits and have contributed to the crisis of livestock management.

Problems to be solved by the invention

  The present inventor has earnestly studied a deodorizing method for neutralizing and masking malodorous gas generated from a compost fermenter that composts livestock manure, agricultural and forestry waste, food processing residue, rice husk, wood chips, Woody biomass, such as wood chips, neutralizes malodorous gases such as ammonia gas generated from a compost fermenter in a composting house with soot gas containing organic acids generated in a carbonization furnace that produces wood charcoal with low oxygen supply Then, after the masking, the compost house deodorizing apparatus and the compost house deodorizing method are proposed in which the air inside the compost house is adsorbed on the fine branch leaves and decomposed by microorganisms, and then the residual malodorous gas is deodorized.

Malodorous gases generated from compost fermenters that compost livestock manure, agricultural and forestry waste, and food processing residues are often produced in the compost fermentation process from the beginning to the middle, producing ammonia gas, hydrogen sulfide, and other odorous gases. In the compost fermentation process after the mid-term, many compost odors such as methyl mercaptan are generated. Of course, in addition to this, generation of malodorous gas components having many complicated components such as amines and aldehydes is observed. In particular, ammonia gas has a high concentration and has a strong irritating odor, so it is necessary to deodorize it preferentially.

Crude wood vinegar liquid obtained by cooling and liquefying soot gas generated in a carbonization furnace that produces wood charcoal with a small amount of oxygen supplied to woody biomass such as rice husk, wood chips, wood chips, etc. The pyroligneous acid solution contains an acidic component, a phenolic component, a basic component, an organic component such as a carbonyl component, and a non-carbonyl component. Spray inside and neutralize malodorous gases such as alkali components with soot gas of acidic components, sulfur compounds such as methyl mercaptan, methyl sulfide, hydrogen sulfide, amines such as trimethylamine, lower fatty acids with soot gas A deodorizing method for masking odors has been carried out.

However, the malodorous gas generated from the composting fermenter in the composting house is in a high temperature state (60 to 70 ° C.), and therefore, an upward air flow occurs from the composting fermenter to the top of the composting house. The boiling point is 118 ° C., and the organic acids in the pyroligneous acid solution containing acetic acid cannot be vaporized instantaneously because the boiling temperature of the organic acids is higher than the house temperature (50 ° C. or lower). For this reason, most of the fine water droplets of the sprayed wood vinegar liquid fall on the surface of the compost fermenter before being vaporized. Therefore, it was impossible to instantaneously neutralize and mask the malodorous gas with the fine water droplets of the pyroligneous acid liquid by spraying the pyroligneous acid liquid into the compost house.

Therefore, the present inventor, as a method capable of instantaneously neutralizing and masking malodorous gas such as ammonia gas, includes an organic acid generated in a carbonization furnace that produces wood charcoal with a small amount of oxygen supplied to woody biomass. This paper proposes a composting deodorizing apparatus and its deodorizing method that enables neutralization and masking instantaneously by directly contacting smoke gas with malodorous gas.

Usually, wood chips having a high carbon nitrogen ratio (C / N ratio = 300 to 500) cannot be composted without applying a nitrogen fertilizer such as ammonium sulfate and adjusting the carbon nitrogen ratio. On the other hand, composting of fine branch leaves uses fermented bacteria by utilizing nitrogen contained in malodorous gas such as ammonia gas 10 to 100 ppm generated during compost fermentation of crushed leaves and fibrous branches. Odor gas is reduced to promote the composting of the fine branch branches and leaves, and the residual malodorous gas is masked by the unique phyton chit odor of the fine branch branches and exhausted to the atmosphere with odorless air.

Furthermore, by mixing and feeding the mature fine branch leaves together with the livestock manure into the compost fermenter, the generation of malodorous gas generated during the compost fermentation of livestock manure is reduced. The aged fine branch and leaves are suitable as an instantaneous fermenting agent that promotes compost fermentation of livestock manure.
