Problems solved by technology

The current mainstream treatment route for catering waste is "pretreatment + three-phase separation + anaerobic digestion + solid residue incineration". Pay the treatment fee; ②The produced wastewater must enter the anaerobic digestion system and water treatment system, the system is complicated and the treatment cost is high; ③The biogas produced by anaerobic is difficult to supply continuously and stably, and the waste of resources is caused by torch incineration
When the processing capacity of this route reaches 100t / d, the processing company can achieve a balance of income and expenditure; due to the low daily output of kitchen waste in a large number of third- and fourth-tier cities, when this technical route is adopted, the processing cost is as high as 400 yuan or even higher

Embodiment 1

[0024] A food waste pretreatment coupling power generation system applied to a thermal power plant, which consists of: a receiving bin 1, a sorter 2, a crusher 3, a dry-wet separation device 4, a heater 5, a three-phase separator 6, a storage Oil tank 61, mixer 41, conveying device, boiler 421 and drying device 422;

[0025] The receiving bin is arranged underground, and the level of the bin opening is flush with the ground. After the vehicle arrives at the bin opening, the bin cover is opened, and the food waste is unloaded into the bin 1. After the bin cover is closed, the bottom of the bin is arranged The conveyor transports the garbage to the sorting machine, and the food waste sorted by the sorting machine enters the crusher. The crusher 3 can be set to one-stage crushing or multi-stage crushing. After the machine is crushed, it enters the dry-wet separation device, and the dry-wet separation device can be a commonly used screw press or plate-and-frame filter press;

Abstract

The invention discloses a food waste pretreatment coupling power generation system applied to a thermal power plant. Produced wastewater needs to enter an anaerobic digestion system and a water treatment system, the system is complex, and the treatment cost is high; biogas generated by anaerobic treatment is difficult to continuously and stably supply, and resource waste is caused by torch incineration. The system comprises a material receiving bin (1), a sorting machine (2), a crusher (3), a dry-wet separation device (4), a heater (5), a three-phase separator (6), an oil storage tank (61), a mixer (41), a conveying device, a boiler (421) and a drying device (422). The system is used for food waste pretreatment coupling power generation of the thermal power plant.

Description

technical field [0001] The invention belongs to the field of solid waste disposal, and in particular relates to a coupled power generation system for catering waste pretreatment applied to thermal power plants. Background technique [0002] With the great development of my country's economic construction, the destruction of the ecological environment has increasingly become an obstacle restricting the continued development of the national economy. The most urgent problem is the various garbage produced in human daily production and life. The current mainstream treatment route for catering waste is "pretreatment + three-phase separation + anaerobic digestion + solid residue incineration". Pay the treatment fee; ②The produced wastewater must enter the anaerobic digestion system and water treatment system, the system is complicated and the treatment cost is high; ③The biogas produced by anaerobic is difficult to supply continuously and stably, and the resources are wasted throu...
