Method for converting crop straws into gaseous fuel

Abstract

The invention belongs to the field of application of biomass energy and particularly relates to a method for converting crop straws into gaseous fuel. The method comprises the following steps: dryingstraws, putting the dried straws into a pulverizing machine and pulverizing to obtain straw granules; putting the straw granules into a straw vaporization furnace and performing vaporization to obtainmixed gas and straw waste; performing electric field and laser treatment on the mixed gas under 2 to 10 MPa; and collecting the straw waste to apply fertilizer so as to realize maximum utilization ofresources, wherein the straw vaporization furnace comprises a furnace body, a first sealing cover, a handle, a fan, a placing plate, a ventilating pipe and a combustion module; the furnace body is cylindrical; the first sealing cover is horizontally placed at the top of the furnace body; and the combustion module is used for combusting the straws entering the furnace body. During use, the first sealing cover is lifted, the straws are put into the combustion module in the furnace body and are ignited, the fan is turned on, and the fan conveys the air into the furnace body through the ventilating pipe and an air inlet, so that the straws are converted into the gaseous fuel.

Description

technical field [0001] The invention belongs to the field of biomass energy application, and specifically relates to a method for converting crop stalks into gaseous fuels. Background technique [0002] As we all know, China is a big agricultural country, which produces hundreds of millions of tons of various straws every year, such as wheat straw, peanut straw, potato straw and sesame straw. In the past, humans chose to burn straws on the spot for convenience. Although it saved time for farmers, it brought great pollution to the environment and air, and human life was also affected. In fact, crop straw can be transformed into resources to realize full utilization of straw. There are many ways to deal with straw, such as chemical method, thermal spraying method, cooking method, etc. Among them, chemical method is eliminated due to environmental protection and high processing cost; thermal The spraying method needs to cook the treated straw raw materials for a long time to k...

In the past, humans chose to burn straws on the spot for convenience. Although it saved time for farmers, it caused great pollution to the environment and air, and human life was also affected.

In fact, crop straw can be transformed into resources to realize full utilization of straw. There are many ways to deal with straw, such as chemical method, thermal spraying method, cooking method, etc. Among them, chemical method is eliminated due to environmental protection and high processing cost; thermal The spraying method needs to cook the treated straw raw materials for a long time to keep the pressure and the sprayed material needs to be cooled for a long time. Since the cooking method takes a longer time to cook the straw, it takes more time than the thermal spraying method and causes more energy consumption, which will directly cause straw high product cost
