Pulse detonation gas type straw comprehensive treatment device with tail heat recovery function and heat exchanger

Abstract

The invention discloses a pulse detonation gas type straw comprehensive treatment device with a tail heat recovery function and a heat exchanger. The pulse detonation gas type straw comprehensive 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; the upper right part of the biogas fermentation tank is connected with the tank bottom through a pipeline and a Roots fan, an outlet of the Roots fan is connected with the biogas storage tank, and the biogas storage tank is connected with the biogas boiler through a pipeline and the biogas burner; the biogas boiler is connected with the countercurrent drying tower through a steam fin hot air machine, the upper left part of the countercurrent drying tower is sequentially connected with a spiral closed-wind feeder and the sine roller, and a tail gas pipe is connected with a heat pump system; and a cosine rubber disk pulse detonation gas device is arranged on the lower left part of the countercurrent drying tower, and a processing device is controlled through the computer. According to the pulse detonation gas type straw comprehensive treatment device, both the sine roller and the cosine rubber disk pulse detonation gas device have distinct characteristics and can reliably and synergisticallyrealize comprehensive development and utilization of crop straw and waste which are particularly large in the moisture content gradient.

Description

technical field [0001] The invention relates to a pulse explosion type straw comprehensive treatment device with tail heat recovery and 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 pulse explosion straw comprehensive treatment device with tail heat recovery and heat exchanger can be designed, it is suitable for...

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.
