Comprehensive straw treatment device with tail heat recycling and closed feeding functions

Abstract

The invention discloses a comprehensive straw treatment device with tail heat recycling and closed feeding functions. The comprehensive straw treatment device comprises a sine roller, a biogas fermentation tank, a biogas storage tank, a countercurrent drying tower, a biogas burner, a biogas boiler, a heat pump main machine and a computer, wherein a sine ultrasonic vibration exciter is arranged atthe left lower part of the biogas fermentation tank; the right upper part of the biogas fermentation tank is connected with the bottom of the biogas fermentation tank through a pipe and a Roots blower; an outlet of the Roots blower is connected with the biogas storage tank; the biogas storage tank is connected with the biogas boiler through a pipe and the biogas burner; the biogas boiler is connected with the countercurrent drying tower through a steam fin heat blower; the left upper part of the countercurrent drying tower is sequentially connected with a spiral closed feeder and the sine roller; a tail gas pipe is connected with a heat pump system; a cosine rubber disc pulse burst device is arranged at the left lower part of the countercurrent drying tower; and the comprehensive straw treatment device is controlled by the computer. The sine roller, the cosine rubber disc pulse burst device and the sine ultrasonic vibration exciter of the comprehensive straw treatment device can reliably and cooperatively achieve comprehensive development and utilization of crop straws and wastes with particularly large water content gradients.

Description

technical field [0001] The invention relates to a straw comprehensive treatment device with tail heat recovery and air-tight feeding. Background technique [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 wastes, and incineration is particularly polluting to the environment. Therefore, it is difficult to efficiently and comprehensively treat agricultural wastes with different moisture content and to carry out efficient waste utilization. If a more advanced straw comprehensive treatment device with tail heat recovery and closed-air feeding can be designed, it is suitable for processing agricultural waste...
