Embodiment 1

[0050] This embodiment provides an odor biological digestion system for food waste treatment equipment, which can fully digest various odorous substances generated during the food waste treatment process, achieving a complete deodorization effect.

[0051] The food waste treatment equipment using the odor biological digestion system includes: unloading platform, sorting platform, crushing system, dehydration system, transmission system and biochemical reaction chamber. Among them, the sorting platform is used to sort out the non-degradable garbage in the kitchen waste; the biochemical reaction chamber is used to ferment the dehydrated solids of the kitchen waste and convert them into usable organic fertilizers.

[0052] Such as Figure 1-3 As shown, according to the order of the treatment process, the odor biodigestion system provided by the present invention includes: gas collection air duct 1, spray tower 2, aerosol separation device 3, photodesorption bin 4, biodigestion bi...

Embodiment 2

[0092] This embodiment provides a process for digestion and treatment of odor generated by food waste treatment equipment, which is applied to the odor biological digestion system for food waste treatment equipment in Example 1. Such as Figure 7-8 As shown, according to the processing sequence, the following processing steps are included in sequence:

[0093] S1: Collect the gas overflowing or generated in the sorting table and biochemical reaction chamber in the food waste treatment equipment.

[0094] S2: The gas collected in the above step is subjected to spraying treatment. The spraying treatment includes at least four stages in turn, and the four stages are respectively treated with neutral, alkaline, acidic and neutral spray liquids.

[0095] Wherein, the spray treatment process is completed in the spray tower, and the spray tower is selected to have four-stage spray chambers arranged horizontally. Wherein, a soda ash solution with a pH value greater than 8.5 and less...

Abstract

The invention relates to the field of environmental protection, in particular to an odor biological digestion system for kitchen waste treatment equipment. According to the sequence of treatment process flows, the system comprises a gas collection air duct, a spray tower, a gas-mist separation device, a photolysis adsorption bin, a biological digestion bin and a controller. The gas collection duct comprises a gas suction pipeline and a negative pressure suction assembly. The spray tower is used for removing particulate matters and part of water-soluble gas in the mixed gas flowing through the spray tower in atomizing and spraying modes. The gas-mist separation device is used for carrying out gas-mist separation on the mixed gas containing mist-like liquid drops. The photolysis adsorption bin internally comprises a buffer cavity, a decomposition cavity and an adsorption cavity which are independent and sealed and are used for respectively realizing photocatalytic cracking and adsorption. A biological digestion solution containing microbial flora is loaded in the biological digestion bin. The controller automatically controls the operation process of the system. The problems that in the existing kitchen waste treatment process, the odor treatment difficulty is large, the digestion efficiency is low, and the treatment cost is high are solved.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to an odor biological digestion system for kitchen waste treatment equipment. Background technique [0002] Food waste contains a large amount of discarded food or food residues, which may contain germs or harmful substances, so they cannot be eaten by poultry or livestock. The current mainstream food waste treatment process is to separate the solid and liquid after crushing and stirring the waste. The separated solid matter is fermented for compost production, and the separated liquid matter can be used for biofuel extraction or biogas production. [0003] During the operation of the food waste treatment station, it is easy to produce the smell of garbage decay and garbage fermentation. These odors are mainly spilled during the process of sorting, crushing and pressing of garbage, or during the degradation and fermentation reaction. The overflow of these odorous gases into...
