Embodiment Construction

[0041] The method for producing liquefied gas by using plant straws includes raw material preparation and liquefied gas preparation. The raw materials are plant straw, rice husk, rice bran, etc., and the straw is crushed and pressed into blocks.

[0042] Making liquefied gas includes the following steps:

[0043] 1. Take 320kg of the prepared raw materials and put them into the gasification chamber 10 of the gasification furnace from the feed port 1 of the gasification furnace. Accounting for 70-80% of the volume of the gasification chamber 10, in order to prevent dead furnace, add 4 kg of solid powdery ethanol to the raw material and stir evenly. The raw materials in the gasification chamber 10 are burned under the condition of lack of oxygen, and the generated flue gas is output from the gas outlet 3 of the gasification furnace.

[0044] 2. Purify. The flue gas that is exported from gasification furnace gas outlet 3 enters in the purifier 1 from the air inlet 12 of purifi...

Abstract

The process of producing liquefied fuel gas with plant stalks includes the following steps: burning plant stalks under anoxic condition inside the gasifying furnace, purifying the fume in the purifier I with 10-15% concentration NaOH solution, dissolving CO in 70-90% concentration alcohol solution in the purifier II while exhausting waste gas, conveying the CO containing alcohol solution via pipeline to the mixed liquid separator, heating to eliminate N and other insoluble gases and separating out CO and other inflammable gas, filtering the CO and other inflammable gas and feeding to storage tank at 10-15 Mpa pressure and 40-60 deg.c temperature, and liquefying CO and feeding to steel cylinder for liquefied gas. The present invention utilizes the organic matters inside plant stalks to produce liquefied gas.

Description

(1) Technical field [0001] The invention belongs to a new method for producing liquefied gas by using agricultural waste, and is a new method for producing high calorific value and canned liquefied gas by using plant straw, shells and bran of crops and fruits. (2) Technical background [0002] my country's thermal energy mainly relies on natural gas, petroleum liquefied gas, and coal, followed by solar energy and electric energy. In rural areas, firewood and plant resources are mainly used as thermal energy. According to the statistics of the International Energy Agency, if the current development trend is If it goes on without restraint or waste utilization, then the three energy sources on the earth, natural gas, petroleum liquefied gas, and coal, can be exploited by human beings for only 40 years, 50 years, and 240 years respectively. Forty or fifty years, from the perspective of human history, is really very, very short. People have realized the limitation of energy reso...
