Problems solved by technology

[0004] The purpose of the present invention is to provide a new type of clean energy produced by deep processing of wood chips and a preparation method to solve the above-mentioned background technology. The current way of processing wood chips generally uses it as fuel, and uses boiler combustion to obtain heat energy. This method will produce air pollution, and The thermal efficiency is low, causing great waste, which is not conducive to environmental protection

Embodiment 1

[0022] The sawdust produced by the plate processing enterprise is crushed by a pulverizer to make it uniform in particle size, free of impurities, and with a moisture content of 10-14%; the treated sawdust is sent into the reaction kettle, and steam is added for heating and wetting. Control at 75°C, keep the temperature constant for 1 hour, and empty the non-condensable gas; put the catalyst into the container, and then add deionized water, so that the catalyst concentration ratio is 1 / 1000; the prepared catalyst and wood chips are in the ratio of 1:10 Use the pump to uniformly atomize and send it into the reactor, raise the temperature to 90°C, and keep the temperature constant for 8 hours, so that the sawdust can be fermented and decomposed in the reactor, and then fermented and decomposed to produce multi-component fractionated oil. The bottom controls the liquid level, extracts it evenly, and then flows into the kettle liquid separation tank through the liquid discharge por...

Embodiment 2

[0024] The sawdust produced by the plate processing enterprise is crushed by a pulverizer to make it uniform in particle size, free of impurities, and the moisture content is controlled at 10-14%; the treated sawdust is sent into the reaction kettle, and steam is added for heating and wetting. The temperature was controlled at 80°C, kept at constant temperature for 1 hour, and the non-condensable gas was evacuated; the catalyst was put into the container, and then deionized water was added to make the catalyst concentration ratio 1 / 1000; the prepared catalyst and wood chips were mixed according to the ratio of 1:10 The ratio is uniformly atomized and sent into the reaction kettle by pump, the temperature is raised to 95°C, and the temperature is kept constant for 8 hours, so that the wood chips are fermented and decomposed in the reaction kettle, and then fermented and decomposed to produce multi-component fractionated oil. After the reaction kettle is cooled to 35°C, the The l...

Embodiment 3

[0026] The sawdust produced by the plate processing enterprise is crushed by a pulverizer to make it uniform in particle size, free of impurities, and the moisture content is controlled at 10-14%; the treated sawdust is sent into the reaction kettle, and steam is added for heating and wetting. The temperature was controlled at 82°C, kept at constant temperature for 1 hour, and the non-condensable gas was evacuated; the catalyst was put into the container, and then deionized water was added to make the catalyst concentration ratio 1 / 1000; the prepared catalyst and wood chips were mixed according to the ratio of 1:10 The ratio is uniformly atomized by a pump and sent to the reactor, the temperature is raised to 98°C, and the temperature is maintained for 8 hours, so that the wood chips are fermented, decomposed and matured in the reactor, and then fermented and decomposed to produce multi-component fractionated oil. After the reactor is cooled to 35°C, the The liquid level is con...

Abstract

The invention discloses a novel clean energy produced via deep processing of sawdust and a preparation method of the novel clean energy. The preparation method comprises the steps of S1, processing sawdust, to be specific, crushing sawdust from board processing enterprises with a crushing machine so that particle size of the sawdust is uniform, with no impurities present and water content being 10-14%; S2, heating and moistening, to be specific, conveying the processed sawdust into a reactor, introducing steam for heating and moistening, controlling the constant temperature to 80-85 DEG C for1 hour, and emptying non-condensed gas; and S3, adding a catalyst, to be specific, adding the catalyst into a container, adding deionized water so that the concentration ratio of the catalyst is 1/1000. The novel clean energy and the preparation method thereof have the advantages that the wood fractionation mode is changed, a boiling fermenting method is utilized, direct heating by waste-heat steam has less energy consumption than indirect heating by steam, and compared with the anaerobic combustion method which requires mass heat and has high energy consumption and material consumption, the boiling fermenting method herein has lower control temperature, more thorough decomposition, zero smoke emission, good waste recyclability and zero ash.

Description

technical field [0001] The invention relates to the field of basic chemical raw materials, in particular to a new type of clean energy produced by deep processing of wood chips and a preparation method. Background technique [0002] Timber generally refers to wooden materials used in industrial and civil construction, and is usually classified as soft wood and hard wood. The wood used in the project is mainly obtained from the trunk parts of trees. Since wood is easy to obtain and process, it has been a major building material since ancient times. Except for the direct use of logs, wood is usually processed into planks or other products for use. The comprehensive utilization rate of wood is an important symbol to measure the level of a country's forestry industry. my country's annual logging of more than 50 million cubic meters of wood, about 40% of which is processed by timber, of which about 10% of the wood is turned into sawdust, so my country's annual output of wood ch...
