Embodiment 1

[0024] Example 1: Preparation of papermaking pulp slag, furfural slag, and sheep manure mixed molding fuel I

[0025] Collect waste papermaking pulp slag, furfural slag, sheep manure and carbonized elements from various manufacturers, and crush the dried papermaking pulp slag to a particle size ≤ 3mm, simply crush the sheep manure, and sieve the furfural slag. Pulp slag 55%, furfural slag 24%, sheep manure 20%, and carbonization 1%. Weigh the treated raw materials, stir to make them evenly mixed, and spray water evenly to the raw materials during the stirring process to keep the water content of the raw materials. 12% of the mass, the uniformly stirred raw materials are stored in an environment with a temperature of 25-30°C and a humidity of 30-35% and stored for 2 days for simple fermentation to form sufficient resilience. Finally, the raw materials after simple fermentation are used in a molding machine Under the conditions of molding pressure 80MPa and molding temperature 1...

[0028] Example 3: Preparation of paper pulp slag, furfural slag, and sheep manure mixed molding fuel III

[0029] Collect waste papermaking pulp slag, furfural slag, sheep manure and carbonized elements from various manufacturers, and crush the dried papermaking pulp slag to a particle size ≤ 3mm, simply crush the sheep manure, and sieve the furfural slag. Pulp slag 65%, furfural slag 17%, sheep manure 15%, and carbonization 3%. Weigh the treated raw materials, stir to mix them evenly, and spray water evenly to the raw materials during the stirring process to keep the water content of the raw materials. 18% of the mass, the uniformly stirred raw materials are stored in an environment with a temperature of 25-30°C and a humidity of 30-35% and stored for 2-3 days for simple fermentation to form sufficient resilience. Finally, the raw materials after simple fermentation are used The molding machine is pressed under the conditions of molding pressure 900MPa and molding temperature...

Abstract

The invention discloses a papermaking pulp residue, furfural residue and sheep manure mixed-formed fuel and a preparation process thereof. The fuel comprises the following components in percentage by weight: 55%-65% of papermaking pulp residue, 15%-25% of furfural residue, 15%-20% of sheep manure and 1%-3% of carbonization elements; the density of the mixed-formed fuel is more than or equal to 1000kg / m<3>, the heat value is more than or equal to 4000 kilocalories per kilogram, and the forming rate is more than or equal to 98%. The preparation process comprises the steps of firstly sieving the furfural residue, grinding charcoal dust and wood residue, weighing each processed raw material in percentage by weight, adding lime powder, uniformly stirring, uniformly spraying water in the stirring process to enable the moisture to be 9%-13% of total mass of the raw materials, stacking to store for 2-4 days, simply fermenting to generate adequate crease recovery, carrying out curing formation by virtue of a foaming machine, and airing in a natural environment until the water content is less than or equal to 8%. The fuel prepared from industrial waste residues has the advantages that the density, the heat value and the forming rate are high, the combustion is adequate, the thermal efficiency is relatively high, the sulfur content is extremely low, the cost is low, and the like; by changing the heat attribute of the fuel by adjusting the proportion, the fuel can be widely applied to industrial boilers or family heating.

Description

technical field [0001] The invention belongs to the field of biomass energy and solid waste reuse, and in particular relates to a mixed molding fuel of papermaking pulp slag, furfural residue and sheep dung, and also relates to a preparation process of the mixed molding fuel. Background technique [0002] At present, various paper mills and furfural factories discard a large amount of pulp residue and furfural residue every year. Cleaning and landfilling increases production costs for enterprises and pollutes the environment. In the prior art, there have been cases of using industrial waste residues as raw materials to process and produce various types of biomass fuels, so as to turn waste into wealth and achieve the environmental protection purpose of energy saving and emission reduction. [0003] However, the combustion properties of biomass fuel used by different biomass boilers are also the same. For example, during the operation of a biomass power plant, it is hoped to ...
