Biomass waste resource pyrolytic carbon gasification comprehensive conversion and utilization system and method

Abstract

The invention relates to a biomass waste resource pyrolytic carbon gasification comprehensive conversion and utilization system and a method employing the system. In the system, a pyrolysis device is connected with a gas supply device through a gas channel of a multifunctional heat exchange device, and is connected with a carbon powder collection device through a pneumatic conveying device. A condensation water channel is connected with a residual warmth heat supplying device through a heat exchanger of the pyrolysis device. According to the method, mixed gas comprising combustible gas, tar gas, and acetic acid gas is produced by high-temperature pyrolysis of a biomass raw material in the pyrolysis device, and carbon is also produced; the mixed gas is absorbed into the multifunctional heat exchanging device and is subjected to heat exchange, and combustible gas and a mixed liquid of tar and acetic acid are separated; water absorbs heat, and enters the heat exchanger of the pyrolysis device, and heat exchange is continued, such that hot water is formed; hot water and combustible gas are respectively delivered through the gas supply device and the residual warmth heat supplying device, such that centralized gas supply, heating, and hot water for residents are realized; acetic acid can be used as a foliar fertilizer or a biocide, or can be mixed with carbon to form a bio-fertilizer; and tar is adopted as an industrial raw material. With the system and the method, a biomass waste resource conversion rate is approximately 100%.

Description

technical field [0001] The present invention relates to a kind of equipment and method for utilization of waste resources such as industrial organic solid waste and agricultural biomass waste, in particular to a kind of equipment and method for the comprehensive conversion and utilization of biomass waste resources pyrolysis carbon gasification mainly based on crop straws. The method is also a comprehensive conversion and utilization device and method for pyrolysis carbon gasification of industrial organic solid waste resources. Background technique [0002] my country is a large agricultural country, and a large amount of biomass resources such as crop straw and slag are produced in agricultural production and agricultural product processing. Traditional utilization methods are mainly used as household energy, feed, fertilizer, industrial raw materials and construction materials. With the modernization of agricultural technology and the rapid development of agricultural ec...

Problems solved by technology

[0008] It can be seen that the above-mentioned existing biomass waste resource pyrolysis carbon gasification conversion utilization system and method obviously still have inconvenience and defects in product structure, manufacturing method and use, and need to be further improved urgently

In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and there is no suitable structure and method for general products and methods to solve the above-mentioned problems. This is obviously a problem that relevant industry players are eager to solve
