Problems solved by technology

This device has two major defects: First, the internal pressure of the carbonizer is in a slightly positive pressure state, and the volatile substances produced by pyrolysis inside the biomass cannot be quickly guided away. The result of the residence time being higher than 2 seconds is that the volatile substances are inside the biomass Or secondary cra

Embodiment Construction

[0022] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing 1 .

[0023] As shown in Figure 1, a vacuum feeder (1) is provided on the upper part of the pyrolysis reactor shell made of stainless steel, and the feed port at the upper end is closely connected with the pyrolysis reactor shell (4) to maintain the reactor and the outside Air isolation; the lower part of the pyrolysis reactor shell is closely connected with the silo (5) through the discharge port, and two pneumatic gate valves are respectively set at the upper and lower outlets of the silo (5) to keep the reactor isolated from the outside air. Multiple sets of molten salt heaters (2) are installed vertically inside the reactor, and each set of molten salt heaters (2) is closely arranged and densely distributed inside the reactor; a gas outlet is set on the upper right of the reactor shell, and the outside is sequentially connected with the rotary ty...

Abstract

The present invention discloses a rapid rice husk pyrolysis apparatus. According to the rapid rice husk pyrolysis apparatus, the main body of a reactor is a stainless steel housing, the upper portion is tightly provided with an vacuum material feeder through a material inlet on the upper end, the lower portion, a screw conveyor and two pneumatic gate valves maintain the reactor and outside air isolation state through a material outlet, multiple groups of molten salt heaters are vertically and densely arranged inside the reactor, a fuel gas outlet is arranged above the right side of the main body, the external is connected to a vacuum pump, a condenser and a filter, and separated combustible gas enters a combustor to combust so as to heat high temperature molten salt adopted as a thermal carrier, such that the energy self-sufficiency can be achieved. With the apparatus of the present invention, the rapid rice husk pyrolysis at the temperature of 450-650 DEG C under the total pressure of 5-15 kPa can be achieved, the natural nanometer structure of the silica inside the rice husk is not damaged, and the complete oxidation of the subsequent combustion oxidation unit impurity carbon is easily achieved.

Description

technical field [0001] The invention relates to a rapid pyrolysis device for rice husks, which is aimed at precise temperature control, rapid pyrolysis, self-sufficiency in energy and reducing fixed carbon output as much as possible under vacuum conditions. In the process of post-temperature-controlled oxidation to produce nano-silicon dioxide. Background technique [0002] my country is a big rice producing country, with an annual output of about 200 million tons of rice, converted into about 40 million tons of rice husks. However, rice husk is not fully utilized as a by-product of rice processing, which not only wastes resources, but also brings great environmental pressure to the improvement of rural environment. In fact, rice husk contains about 15-20% amorphous silica, and the primary particle size of silica is about 50nm, and the distribution is uniform. It is a valuable renewable nano-mineral resource. Therefore, the rice husk pyrolysis-oxidation process can be used...
