[0007] Chinese patent 201110441650.6 discloses a method for biological detoxification of tea seed cake, which uses dipotassium hydrogen phosphate, magnesium chloride, 2000-4000U / g acid cellulase, and microbial strains in the pulverized tea seed cake. Reduce the toxicity in protein, but it is difficult to be used for large-scale oil residue treatment due to the complex operating conditions and difficult control of the process
[0014] However, biomass wears a lot on the molding die and pressure roller during molding, which reduces the service life of the machine (the life of the mold is less than 700 hours, and the life of the pressure roller is less than 10,000 hours), which not only leads to an increase in production costs, but also Not conducive to continuous use of equipment
Although the addition of grease and combustion aid can reduce the loss of equipment and increase the calorific value, it makes the operating procedure too complicated and increases the operating cost, so it is difficult to be widely promoted and applied

Abstract

A mixed biomass briquette and its molding method, a mixed biomass briquette, using oil plant fruit press cake, or a mixture of oil plant fruit press cake and oil plant fruit oil cracking solid phase products and fibers Vegetarian biomass scraps are mixed and pressed into shape. The molding method includes the following steps: (1) pretreatment of raw materials; (2) mixing and molding; that is, mixed biomass molding fuel is obtained. The mixed biomass briquette fuel of the present invention has a high combustion rate, which can solve the problem of oil plant fruit processing waste waste disposal; the molding process has low energy consumption, low equipment loss, and is convenient for large-scale continuous production, and is convenient for transportation and storage; high strength, convenient Transportation and use; The molding method of the mixed biomass briquette fuel of the present invention is a deep utilization of industrial oil waste, and the production process of biomass fuel is optimized by using oil waste. It is easy to operate, low in pollution, small in investment, and easy to scale up Production, less loss of equipment.

Description

technical field [0001] The invention relates to biomass energy utilization and solid waste resource utilization, in particular to a mixed biomass molding fuel and a molding method thereof. Background technique [0002] Since the oil crisis in the 1970s, the main resources used by human beings such as oil, coal, and natural gas have been in short supply, and have gradually attracted the attention of various countries. Consumption is increasing day by day, and the energy crisis is becoming more and more serious. [0003] On the other hand, due to the combustion of a large amount of fossil fuels, NOx, SO 2 and CO 2 The content of ethylene oxide is increasing year by year, which has caused a series of environmental problems such as acid rain and greenhouse effect, and has brought great harm to the natural environment and human life. Therefore, all countries are actively researching waste recycling and new energy sources. [0004] Oil plant fruit processing waste, as a bulk pr...
