Sinusoidal roller type comprehensive straw treatment device capable of recovering afterheat and feeding with gas closed

Abstract

The invention discloses a sinusoidal roller type comprehensive straw treatment device capable of recovering afterheat and feeding with gas closed. The device comprises a sinusoidal roller, a biogas fermentation tank, a biogas storage tank, a counterflow drying tower, a biogas burner, a biogas boiler, a main machine of a heat pump and a computer, wherein the lower left part of the biogas fermentation tank is provided with a sinusoidal ultrasonic exciter, and the upper right part of the biogas fermentation tank is connected to the tank bottom through a pipeline and a roots blower; an outlet of the roots blower is connected to the biogas storage tank, and the biogas storage tank is connected to the biogas boiler through the pipeline and the biogas burner; the biogas boiler is connected to thecounterflow drying tower through a steam fin type hot-air blower; a spiral closed-gas feeder and the sinusoidal roller are sequentially connected to the upper left part of the counterflow drying tower; an exhaust gas pipe is connected to a heat pump system; a treatment device body is controlled through the computer. According to the device, the sinusoidal roller and the sinusoidal ultrasonic exciter have distinct characteristics and reliably coordinately act to comprehensively develop and utilize crops, namely straw, and wastes with high water content gradient.

Description

Technical field [0001] The invention relates to a sine roller type straw comprehensive treatment device with tail heat recovery and closed air feeding. Background technique [0002] Crop straws and agricultural wastes are the main garbage and wastes of the agricultural industry. Nowadays, agricultural wastes are generally treated by crushing straws and returning them to the field, burning and producing biomass fuels. However, returning straws to the fields can not make their rich energy effective. Utilization and manufacturing of biomass fuels have high requirements on the moisture of agricultural wastes, and incineration particularly pollutes the environment, so it is difficult to efficiently and comprehensively treat agricultural wastes with different moisture levels and make efficient waste utilization. If a more advanced sine-roller straw comprehensive treatment device with tail heat recovery and closed air feeding can be designed, it is suitable for agricultural waste proces...

[0002] Crop stalks and agricultural waste are the main garbage and waste in the agricultural industry. Nowadays, agricultural waste is generally treated by crushing straw and returning it to the field, burning it and making biomass fuel, but returning the straw to the field cannot make the energy rich in it effective. Utilization and production of biomass fuels have high requirements on the moisture content of agricultural waste, and incineration is particularly polluting to the environment. Therefore, it is difficult to efficiently and comprehensively treat agricultural waste with different moisture levels and carry out efficient waste utilization.
