Embodiment 1

[0061] Example 1: Production of bulk briquettes from crop straws

[0062] The crushed crop stalks are manually or mechanically stacked in the raw material receiving device 1, and continuously conveyed by the scraper conveying device 2, which can ensure that the raw materials are fully dried and mixed, and the moisture content is consistent. At the same time, according to the requirements of feeding speed and molding speed, the main raw material is prepared in the raw material kneading and crushing device 3, and then enters the raw material inlet 4 after kneading. If the final straw has a high water content, peanut shells should be added, which is conducive to shaping. All the raw materials are lifted to the raw material mixing bin 6 through the scraper conveying device 15 for mixing. Simultaneously can add other additives such as pulverized coal according to user's requirement, therefore through pulverized coal adding device 11 (such as figure 2 Middle AA place) is connecte...

Embodiment 2

[0063] Example 2: Production of pelletized fuel from crop straws

[0064] The requirement of granular briquette fuel is higher than that of block briquette fuel, and the raw material needs secondary crushing. The specific implementation process is as follows:

[0065] The crushed crop stalks are manually or mechanically stacked in the raw material receiving device 1, and continuously conveyed by the scraper conveying device 2, which can ensure that the raw materials are fully dried and mixed, and the moisture content is consistent.

Embodiment 3

[0067] Example 3: Production of block and granule fuel from crop stalks

[0068] According to market demand and raw material situation, this process route can pass through pneumatic tee 18, namely figure 2 In the B place, open the pipeline switches 21 and 23 entering the briquetting section and the granulation section simultaneously, and connect the particle fuel interface 23 to the BB place, so that the machine can produce block and particle molding fuel simultaneously. The working process is the same as in Examples 1 and 2.

[0069] Under normal working conditions, the biomass solid briquette fuel production line built by the present invention is controlled by the electric control center throughout the processing process, including the main control of the central control room and the individual control of main equipment. The main control room is responsible for the start-up and operation monitoring of the entire production line and shutdown, the single control is responsib...

Abstract

The invention discloses a processing method for biomass solid molding fuel, which pertains to the technical field of solid fuel and aims at solving problem of comprehensive use of energy and biomass energy in rural areas. The technical proposal is as follows: biomass energy such as crop straws, shrub forest, forestry residues and the like are used as raw materials, and the secondary crushing technique and the mixed technique combining continuous feeding with adjustable feeding are adopted, therefore, two types of solid fuels, namely, block-type and granular fuels, can be produced. The technical proposal comprises three stages namely, pre-treatment of raw materials, solid molding and auxiliary assorting, and the specific working procedures comprise raw material cracking, drying, conveying, mixing, feeding, molding, cutting, cooling and measuring and packaging and adding a compulsory ventilating dust-removing system during the whole process. The processing method for biomass solid molding fuel solves the problem of diversification of biomass raw materials, and the biomass solid fuel production line constructed by adopting the processing method realizes the industrial continuous and stable production, solves the problems of high energy consumption and low production efficiency in the existing small workshop-style production, and is also beneficial to solving the rural energy problem and improving the rural environment.

Description

technical field [0001] The invention relates to a processing method of biomass solid briquette fuel, which belongs to the field of solid fuel technology, specifically a processing method for processing crop straw and forestry residues into solid briquette fuel, and is used to solve the problems of comprehensive utilization of rural energy and biomass. Background technique [0002] my country is rich in crop straw resources and forest resources. According to statistics, the annual output of crops is about 600 million tons per year, equivalent to about 300 million tons of standard coal, and the forestry residue is about 150 million tons. In recent years, with the continuous improvement of the agricultural economic level, the high-grade commercial energy in rural life has gradually increased, and the proportion of straw is also increasing. A large number of discarded straws are burned in the fields. This phenomenon is not only a waste of A large amount of biomass energy has cau...
