Embodiment 1

[0055] like figure 1 and figure 2 As shown, this embodiment provides an air purification device for biological treatment of food waste, which is installed in a drying room for biological treatment of food waste to perform air purification treatment. The air purification equipment includes a smoke collection assembly 1. The smoke collection assembly 1 includes a smoke collection cover 12 and a bellows box body 11. A wind cabinet 13, a motor 14 and a wind wheel 15 are arranged in the bellows box body 11. The outlet of the wind cabinet 13 and the exhaust The inlet of the flue 19 is communicated; the air purification equipment also includes: a three-way catalytic converter 2, an oil-gas condenser 4, a first one-way valve 3, a first stop valve 44, a second stop valve 45, a third stop valve 46, and the controller 100 . The untreated gas collected by air purification equipment is hereinafter referred to as flue gas.

[0056] Wherein, the three-way catalytic converter 2 is used to...

Embodiment 2

[0079] This embodiment provides an air purification device for biological treatment of kitchen waste. The difference between this embodiment and Embodiment 1 is:

[0080] like Image 6 As shown, in this embodiment, a first air compressor 5 is provided between the outlet of the three-way catalytic converter 2 and the inlet of the oil-gas condenser 4, and the first air compressor 5 is a screw air compressor. In Embodiment 1, the air is driven by the wind wheel 15 in the wind cabinet 13 , discharged into the oil-gas condenser 4 , and the gas backflow is suppressed by the first one-way valve 3 . However, in this implementation, after the first air compressor 5 is used, the pressure value in the oil-gas condenser 4 can be further increased, so as to facilitate the full liquefaction and recovery of oil and gas, and improve the efficiency of liquefaction recovery.

Embodiment 3

[0082] This embodiment provides an air purification device for biological treatment of kitchen waste. The difference between this embodiment and Embodiment 2 is:

[0083] like Figure 7 As shown, in this embodiment, a cooling system 6 is further provided outside the oil-gas condenser 4, such as Figure 8 As shown, the cooling system 6 includes a circulation pipeline 61 , an evaporator 62 , a second compressor 63 , a condenser 64 , a liquid storage tank 65 , a dry filter 66 , a solenoid valve 67 and an expansion valve 68 .

[0084] Refrigerant is set in the liquid storage tank 65, and under the drive of the compressor, the refrigerant flows through the evaporator 62, the second compressor 63, the condenser 64, the liquid storage tank 65, the dry filter 66, and the solenoid valve in sequence along the circulation pipeline 61. 67 and expansion valve 68 to complete the refrigeration cycle. The cooling system 6 is electrically connected with the controller 100, and the controller...

Abstract

The invention belongs to the technical field of environmental protection equipment, and particularly relates to air purification equipment for biological treatment of kitchen waste. The air purification equipment comprises a smoke collection assembly, a three-way catalyst, a switching pipeline, a first air compressor, an oil gas condenser, a first one-way valve, a first stop valve, a second stop valve, a third stop valve, a cooling system and a controller. The smoke collection assembly comprises a smoke collecting hood and an air bellow body, and an air cabinet, a motor and a wind wheel are arranged in the air bellow body. The oil gas condenser internally comprises an oil condensing cavity and an oil collecting cavity; a condensation promoting carrier for promoting liquefaction and condensation of oily gas-phase substances in the smoke is arranged in the center of a cavity body of the oil condensing cavity; the oil condensing cavity is communicated with the oil collecting cavity, an exhaust port is formed in the side wall of the oil collecting cavity, a first gas-liquid separator is installed at the exhaust port, and an oil discharging port is formed in the bottom of the oil collecting cavity; the air purification equipment has good harmful gas purification and oil gas liquefaction recovery performance, the liquefaction recovery rate of volatile oil gas is very high, and the energy-saving and environment-friendly performance is outstanding.

Description

technical field [0001] The invention belongs to the technical field of biological environmental protection, and in particular relates to an air purification device for biological treatment of kitchen waste. Background technique [0002] Food waste contains a large amount of discarded food or food residues, which can be used as raw materials for the production of feed or fertilizer. The current mainstream food waste treatment process is to crush the waste and then squeeze it to complete the solid-liquid separation; the separated solids are fermented for compost production, or used to prepare feed after drying. The separated liquid substances can be used to extract biofuel or carry out biogas production, etc. [0003] The process of using the solids separated from food waste to produce feed often requires drying and sterilization of the solids in the food waste. The conventional drying and sterilization method is to carry out high-temperature drying in the drying treatment r...
