specific Embodiment approach

[0007] The specific embodiment of product of the present invention is:

[0008] 1. Pretreatment of main materials and auxiliary materials:

[0009] Main material pretreatment: gather the discarded mushroom sticks after planting edible fungi to the crushing site, manually remove the outer plastic bag, take out the waste fungus residue, and crush them with a crusher until the diameter of the crushing is less than 3 mm.

[0010] Pretreatment of auxiliary materials: auxiliary materials can be selected according to the situation straw powder (corn stalk, wheat straw, soybean stalk, cotton stalk), tree branch, hay powder, wood chips, cottonseed shell, fruit shell powder, peanut shell, coconut shell, coal powder, Several kinds of coke powder and binder, mixed evenly.

[0011] 2. Mixing treatment:

[0012] According to the ratio of main and auxiliary materials of 7:3, the pretreated main materials and auxiliary materials are mixed, and stirred evenly with a mixer, and clean water is...

Embodiment 1

[0018] Embodiment 1: Get 11,000 bags of discarded bacterium sticks after the primary cultivation of Pleurotus eryngii and Pleurotus eryngii, manually remove the plastic outer film, and pulverize the waste residue, about 700 kilograms. Take 200 kilograms of sawdust, 90 kilograms of coke powder, and 10 kilograms of binder, mix and stir evenly, make wet material, extrude into a rod-shaped product with a diameter of 5 centimeters and a length of 50 centimeters with a pressure of 200 tons, and dry to obtain a finished product.

Embodiment 2

[0019] Embodiment 2: Get each 3000 bags of discarded bacterium sticks after the primary cultivation of Coprinus comatus and black oyster mushroom, manually remove the plastic outer film, and pulverize the waste residue, about 350 kilograms. Take 100 kg of cotton straw powder, 45 kg of coal powder, and 5 kg of binder, mix and stir evenly, make wet material, extrude with 300 tons of pressure into a round cake-shaped product with a diameter of 10 cm, and dry to obtain the finished product.

Abstract

In recent years, with the rapid growth of the traditional edible fungus industry all over China, the pollution and the hazard generated to the entironment and the edible fungus industry per se by a large number of obsolete fungus sticks (slags) after the primary planting of edible fungi also become bigger and bigger, and the innocent treatment and the research development in the aspect of reutilization on the obsolete fungus sticks in the industry also become more and more, wherein the research of preparing the biomass fuel by taking the obsolete fungus sticks is an important research direction. The invention provides a method for preparing the biomass fuel by taking the obsolete fungus sticks and the fungus slags of the edible fungi as the main materials; the method has low cost and belongs to the field of waste comprehensive development and deep utilization. In the invention, the obsolete fungus sticks and the fungus slags of the edible fungi are used as the main materials, wherein the weight proportion is higher than 50 percent; the mixture ratio of other auxiliary materials is simple and varied and most of auxiliary materials is crop wastes; then the main ingredients and the auxiliary materials are extruded to be formed and then dried, thereby preparing the biomass fuel. In the invention, the biomass fuel can be processed into products with different density and shapes by adopting common biomass fuel forming equipment in the market. The products of the invention have high heat value and do not have smoke or stink; under the simple conditions, common peasant households can prepare and use the biomass fuel on the spot; the biomass fuel is a novel environment-friendly fuel. In the edible fungus scale planting areas, waste utilization is effectively realized, and pollution sources can be thoroughly eliminated.

Description

technical field [0001] The invention relates to the field of comprehensive development and deep utilization of waste, in particular to a method for preparing biomass fuel from edible fungus planting waste. technical background [0002] In recent years, with the rapid rise of the traditional fungus industry in various parts of my country, a large number of discarded mushroom sticks (slag) after one planting of edible fungi have become more and more polluting and harmful to the ecological environment and the edible fungus industry itself. There are more and more researches in the industry on the harmless treatment and secondary utilization of waste bacterial sticks. Among them, the research on making biomass fuel from waste bacteria sticks is also an important research direction. At present, there is no domestic development and application of using waste mushroom sticks as the main material to produce biomass fuel. Compared with the production of traditional biomass fuels, th...
