Pulse aeration type comprehensive straw treatment device with tail gas recycling and air sealed material feeding

Abstract

The invention discloses a pulse aeration type comprehensive straw treatment device with tail gas recycling and air sealed material feeding. The device comprises a sine roller, a biogas fermentation tank, a biogas storage tank, a counter-flow drying tower, a biogas combustor, a biogas boiler, a heat pump main machine and a computer, wherein the upper right part of the biogas fermentation tank is connected with a tank bottom through a pipeline and a Roots blower; the outlet of the Roots blower is connected with the biogas storage tank; the biogas storage tank is connected with the biogas boilerthrough a pipeline and the biogas combustor; the biogas boiler is connected with the counter-flow drying tower through a steam fin hot air machine; a spiral air sealed material feeding machine and thesine roller are sequentially connected with the upper left part of the counter-flow drying tower; a tail gas tube is connected with a heat pump system; a cosine pulse disc pulse aeration device is arranged at the lower left part of the counter-flow drying tower; the treatment device is controlled by the computer. The sine roller and the cosine pulse disc pulse aeration device of the device both have distinct characteristics, and crop straw and wastes with particularly large moisture content gradients can be comprehensively developed and utilized in a reliable synergetic manner.

Description

technical field [0001] The invention relates to a pulse explosion type straw comprehensive treatment device with tail heat recovery and closed-air 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 pulse-explosive straw comprehensive treatment device with tail heat recovery and closed-air feeding can be designed, it is suit...

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.
