Self-stirring continuous biomass hydrothermal pretreatment device driven by solar energy

Abstract

The invention discloses a self-stirring continuous biomass hydrothermal pretreatment device driven by solar energy. The hydrothermal pretreatment device comprises an auxiliary heater, a material storage tank, a stirring device, a solid-liquid mixed material extraction pump, a solar collecting lens, a heat collector assembly, a temperature sensor and a material collecting tank; the auxiliary heaterand the stirring device are arranged in the material storage tank; one end of the solid-liquid mixed material extraction pump is connected with one end of a water pipe, the other end of the water pipe is arranged in the material storage tank, the other end of the solid-liquid mixed material extraction pump is connected with one end of a hydrothermal pipe, the other end of the hydrothermal pipe isconnected with one end of the water pipe, and the other end of the water pipe is arranged in the material collecting tank. The self-stirring continuous biomass hydrothermal pretreatment device drivenby solar energy has the advantages of being detachable, convenient to clean, capable of realizing continuous production, and capable of effectively preventing the solid part from precipitating in thematerial, and the problems of large energy consumption, incapability of large-scale continuous production, difficulty in disassembly, inconvenient cleaning and incapability of uniformly treating materials due to precipitation in the prior art are solved.

Description

technical field [0001] The invention belongs to the technical field of hydrothermal pretreatment, in particular to a self-stirring continuous biomass hydrothermal pretreatment device driven by solar energy. Background technique [0002] The hydrothermal pretreatment of biomass is a method of pretreating biomass with subcritical water heated above the boiling point and below the critical point. Due to its special properties, the water at this time can effectively accelerate the dissolution and degradation of biomass. However, the current hydrothermal method generally has the following problems: a large amount of fossil energy needs to be consumed in the process of pretreatment of biomass; and the commonly used hydrothermal reactor can only achieve small-scale batch production, so it is urgent to find a A method that can use the hydrothermal method to continuously pretreat biomass in large quantities and effectively reduce energy consumption. As a new energy source, solar ene...
