preparation example Construction

[0031] According to the second aspect of the present invention, the present invention provides a method for preparing the above-mentioned biomass briquette, including the following steps:

[0032] (1) Mix the waste liquid of the paper mill, coal tar and water in a weight ratio of 6.5-8:1.8-2.5:0.8-1.2 (preferably 7:2:1) to obtain a binder;

[0033] (2) Add 40-60 parts by weight of coke, 28-48 parts by weight of sterilized livestock and poultry manure, 2-22 parts by weight of waste activated carbon, and 0.5-15 parts by weight of oil sludge into the reactor in sequence, and then add the step ( 1) 0.5-15 parts by weight of the prepared adhesive is bonded to obtain a semi-finished product;

[0034] (3) Dry the semi-finished products.

[0035] In the above method, the disinfected livestock and poultry manure is dried at 70-90°C for 4-6 hours before use to make the moisture content 2wt%-3wt%; the sludge is dried at 70-90°C before use Dry for 10-15 hours so that the moisture content is 5wt%...

Embodiment 1

[0060] The biomass briquette of this embodiment is made of the following raw materials: 50 parts by weight of coke, 38 parts by weight of sterilized livestock and poultry manure, 12 parts by weight of waste activated carbon, 5 parts by weight of sludge, and 5 parts by weight of binder.

[0061] The preparation method of biomass briquettes in this embodiment is as follows:

[0062] (1) Mix the waste liquid of the paper mill, coal tar and water according to the weight ratio of 7:2:1 to obtain the binder;

[0063] (2) Add 50 parts by weight of coke, 38 parts by weight of sterilized livestock and poultry manure, 12 parts by weight of waste activated carbon, and 5 parts by weight of oil sludge into the reactor in sequence, and then add the binder 5 prepared in step (1) Parts by weight are bonded and molded to obtain semi-finished products;

[0064] (3) Dry the semi-finished product at 1000°C for 10 hours.

Embodiment 2

[0066] The biomass briquette of this embodiment is made of the following raw materials: 45 parts by weight of coke, 33 parts by weight of sterilized livestock and poultry manure, 10 parts by weight of waste activated carbon, 2 parts by weight of sludge, and 2 parts by weight of binder.

[0067] The preparation method of biomass briquettes in this embodiment is as follows:

[0068] (1) Mix the waste liquid of the paper mill, coal tar and water according to the weight ratio of 6.5:1.8:0.8 to obtain the binder;

[0069] (2) Add 45 parts by weight of coke, 33 parts by weight of sterilized livestock and poultry manure, 10 parts by weight of waste activated carbon, and 2 parts by weight of oil sludge into the reactor in sequence, and then add the binder prepared in step (1) 2 Parts by weight are bonded and molded to obtain semi-finished products;

[0070] (3) Dry the semi-finished product at 1200°C for 7 hours.

Abstract

The invention provides biomass briquette coal which is prepared from the following raw materials in parts by weight: 40 to 60 parts of coke, 28 to 48 parts of disinfected excrements of livestock, 2 to 22 parts of waste activated carbon, 0.5 to 15 parts of oil sludge and 0.5 to 15 parts of a binder. The invention further provides a preparation method for the biomass briquette coal, and the preparation method comprises the following steps: uniformly mixing papermaking plant waste liquor, coal tar and water in a weight ratio of (6.5 to 8) to (1.8 to 2.5) to (0.8 to 1.2) to obtain a binder; sequentially adding 40 to 60 parts of coke, 28 to 48 parts of disinfected excrements of livestock, 2 to 22 parts of waste activated carbon and 0.5 to 15 parts of oil sludge into a reactor to crush, then, adding 0.5 to 15 parts of the binder to bind and form, thereby obtaining a semi-finished product; and drying the semi-finished product. The product and the method provided by theinvention have positive significance in improving energy structure and promoting waste recycling development.

Description

Technical field [0001] The present invention belongs to the technical field of clean coal. Specifically, the present invention relates to a biomass briquette and a preparation method thereof, and more specifically, the present invention relates to a biomass briquette using livestock manure and industrial waste as raw materials and preparation thereof method. Background technique [0002] At present, with the development of the economy, the output of solid waste is increasing, and a large amount of waste is disposed of in landfills and incineration, which is increasingly contradictory to the local society. However, in some industries, such as animal husbandry or mechanical processing, some solid wastes still have great potential in terms of calorific value that can be tapped. From the perspective of safety technology, there are still sufficient guarantees that can be applied. At the same time, with the strict environmental protection standards of the atmosphere, it is becoming a ...
