Embodiment 1

[0025] combined reference figure 2 As shown, the environmental protection comprehensive treatment method of kitchen waste and waste oil of the present invention further includes the steps:

[0026] Step S1: Separating the kitchen waste from the kitchen into solid-liquid after biological deodorization;

[0027] Step S2: On the one hand, the solid waste is crushed into waste particles with a particle size of 1-2cm by a tooth crusher, and the crusher is connected to the drying unit through a pipeline; under normal pressure, the pre-pyrolysis temperature is 100-400°C, The pyrolysis time is 1 to 3 hours, and the flammable gas generated by the reaction is directly injected into the hot blast stove for combustion;

[0028] The tail gas produced after drying is discharged into the cooling scrubber, which is connected to the three-phase separator, in which, the hot water coming out is connected to the water treatment system through pipelines, part of the water is discharged into the ...

[0035] The environmental protection comprehensive treatment method of kitchen waste and waste oil of the present invention further includes the steps of:

[0036] Step S1: Separating the kitchen waste from the kitchen into solid-liquid after biological deodorization;

[0037] Step S2: On the one hand, the solid waste is broken into 1-2cm garbage particles by the tooth crusher, and sent to the pre-pyrolysis device (drying unit) by the sealed screw conveyor for preliminary drying; The pyrolysis device is an externally heated piston propeller, scraper machine or screw conveyor. Under normal pressure, the pre-pyrolysis temperature is 100-400°C, and the pyrolysis time is 1-3 hours. The flammable gas generated by the reaction is directly injected into the hot air. burning in the furnace;

[0038] Step S3: On the other hand, the garbage liquid is divided into two parts by the oil-water separation system, and a part of waste oil (slug oil) is preheated and used as fuel for burning by...

Abstract

The invention discloses an environment-friendly comprehensive treatment method for kitchen garbage and waste oil. The method comprises the following steps of: (1), carrying out biological deodorization and solid-liquid separation on the kitchen garbage; (2), on the one hand, crushing the solid garbage into garbage particles with particle size of 1cm-2cm through a tooth type crusher, and preheating, drying and dry-distilling the garbage particles into charcoal through a sealing type spiral conveyor; (3), on the other hand, separating a garbage liquid into two parts by an oil-water separating system, wherein one part of waste oil is used as fuel for the combustion of a heat supply draft furnace, so that the kitchen garbage is dried, distilled and converted into charcoal; and (4), treating the other part of the wastewater through a biological wastewater treatment system and discharging the treated wastewater after the treated wastewater reaches the standard. The comprehensive treatment method disclosed by the invention is a technology for enabling the kitchen garbage to be harmless, reduced and recycled; and moreover, the treatment process is free of pollution, low in cost, good in practicability and operability, and remarkable in economic benefits and social benefits.

Description

technical field [0001] The invention relates to the technical field of environmental protection utilization of waste, in particular to an environmental protection comprehensive treatment method for kitchen waste and waste oil. Background technique [0002] In the era of industrialization, the amount of industrial waste and domestic waste generated by cities is huge, and the speed of processing them is much slower than the speed of waste generation. Quite a few cities have encountered the dilemma of being surrounded by waste. There are generally two ways to deal with garbage, one is direct landfill, and the other is burning, which produces highly toxic dioxins and secondary pollution. According to a recent survey by relevant departments, more than 76% of households are left with leftovers, leftovers, vegetable leaves, fruit peels and other kitchen waste, followed by plastic cans and garbage bags. [0003] According to statistics, a city with a population of more than one mil...
