Mixed biomass briquette fuel and forming method thereof

Abstract

The invention relates to a mixed biomass briquette fuel and a forming method thereof. The mixed biomass briquette fuel is prepared by mixing a mixture of an oil plant fruit squeezed cake or an oil plant fruit squeezed cake and an oil plant fruit oil-cracked solid-phase product with cellulose type biomass scrap, pressing and forming. The forming method comprises the following steps: (1) pretreatment of raw materials; and (2) mixing and forming to obtain the mixed biomass briquette fuel. The mixed biomass briquette fuel provided by the invention has high burning rate, and can solve the disposal problem of oil plant fruit processing wastes and waste materials; the forming method has the advantages of low energy consumption in forming process, small equipment loss, and is convenient for large-scale continuous production and convenient for transportation and preservation; the strength is high, and the transportation and the use are convenient; the forming method of the mixed biomass briquette fuel, provided by the invention, can realize deep utilization of industrial oil wastes, and utilize the oil wastes to optimize a production process of biomass fuel and has the advantages of low pollution, low investment and small equipment loss and is simple to operate, and large-scale production is easy to carry out.

Description

Technical field [0001] The invention relates to the utilization of biomass energy and the resource utilization of solid waste, in particular to a hybrid biomass molding fuel and a molding method thereof. Background technique [0002] Since the emergence of the oil crisis in the 1970s, major human resources such as oil, coal, and natural gas have been in short supply, and have gradually attracted attention from various countries. At the same time, as the world’s population and people’s living standards improve, various types of non-renewable energy Consumption is increasing and the energy crisis is getting worse. [0003] On the other hand, due to the burning of a large amount of fossil fuels, NOx and SO in the air 2 And CO 2 Such content has increased year by year, causing a series of environmental problems such as acid rain and the greenhouse effect, which have brought great harm to the natural environment and human life. Therefore, all countries are actively studying waste recycl...

[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
