A modular agricultural and forestry waste comprehensive conversion device

Abstract

The invention discloses a modular comprehensive conversion device for forestry and agricultural wastes. The modular comprehensive conversion device comprises a pulverizer, a conveyor belt, a conversion reactor, a non-pressure biofuel heating machine, a solid-liquid separation device, a solar hot air drying system, a briquetting machine and a rectifying tower, which are arranged on a modular assembling frame, wherein a stirring device is arranged on the top of the conversion reactor downwards, a water-circulating heating pipeline is coiled on the side walls at the periphery of the conversion reactor, a feeding hole, a catalyst charging hole and a gas outlet are arranged at the upper part of the conversion reactor and a discharging hole is arranged at the bottom of the conversion reactor; the non-pressure biofuel heating machine is connected with the water-circulating heating pipeline; the discharging hole of the conversion reactor is connected with an inlet of the solid-liquid separation device, a liquid outlet of the solid-liquid separation device is connected with an inlet of the rectifying tower, a solid outlet of the solid-liquid separation device is connected with an inlet of the solar hot air drying system, and an outlet of the solar hot air drying system is connected with an inlet of the briquetting machine. The modular comprehensive conversion device has the advantages of good energy-saving and environment protection effects, detachability and high economic benefit.

Description

technical field [0001] The invention relates to an agricultural and forestry waste treatment device, in particular to a modular agricultural and forestry waste comprehensive transformation device. Background technique [0002] At present, as a major producer of agriculture and forestry, my country produces a huge amount of agricultural and forestry waste every year. In the past, these wastes were mostly used as fuel and treated with simple and extensive methods such as incineration on site, which not only caused a huge waste of resources, but also brought heavy pressure to the environment. China is a large agricultural country. With the continuous improvement of agricultural production and farmers' living standards, the utilization of agricultural wastes that were originally used as fertilizers and fuels is less and less, so agricultural wastes are increasing. my country has become the country with the largest output of agricultural waste in the world, with an annual output...

AI Technical Summary

Problems solved by technology

Most of these wastes are discarded as garbage or discharged into the environment, resulting in waste of available resources and pollution of the ecological environment.

At present, although there are quite a lot of newly developed comprehensive utilization methods of biomass resources, and some of them have relatively high utilization rate of biomass resources, due to the high cost of infrastructure investment, the collection and transportation of agricultural and forestry wastes are expensive, and consume a certain amount of heat energy. , the economic benefits are low, so the total amount of agricultural and forestry waste disposal is small, and the problem of the disposal and utilization of agricultural and forestry waste resources cannot be fundamentally solved
