Convex rib roller type straw comprehensive treatment device with heat exchanger

Abstract

The invention discloses a convex rib roller type straw comprehensive treatment device with a heat exchanger. The device consists of a convex rib roller, a biogas fermentation tank, a biogas storage tank, a countercurrent drying tower, a biogas burner and a biogas boiler. The left bottom of the biogas fermentation tank is equipped with a sinusoidal ultrasonic vibration exciter, the right upper partis connected to the tank bottom through a pipeline and a Roots blower, the outlet of the Roots blower is connected to the biogas storage tank, the biogas storage tank is connected to the biogas boiler through a pipeline and the biogas burner, the biogas boiler is connected to the countercurrent drying tower through a steam fin air heater, the left upper part of the countercurrent drying tower isconnected to a spiral air-lock feeder and the convex rib roller, and the left lower part of the countercurrent drying tower is equipped with a cosine rubber plate pulse aeration apparatus. According to the invention, the convex rib roller, the cosine rubber plate pulse aeration apparatus and the sinusoidal ultrasonic vibration exciter all have distinct characteristics, and can cooperate reliably to achieve comprehensive development and utilization of crop straw and waste with special large moisture content gradient.

Description

technical field [0001] The invention relates to a ribbed roller-type straw comprehensive treatment device with a heat exchanger. 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 ribbed roller comprehensive treatment device with heat exchanger can be designed, it is suitable for agricultural waste processing with large moisture con...

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.
