Description

Technical Field

[0001] The invention relates to the technical field of solid waste regeneration, and in particular to a solid waste regeneration fuel ball and a processing method thereof. Background Art

[0002] Solid waste recycled fuel balls (hereinafter referred to as "fuel balls") are usually spherical fuels made from combustible solid wastes such as municipal solid waste, industrial waste, and biomass after sorting, crushing, drying, and compression molding. These fuel balls have a high calorific value and can be used as a renewable energy source to replace traditional fossil fuels.

[0003] Existing solid waste recycled fuel balls are formed by processing combustible solid wastes such as urban solid waste, industrial waste, and biomass, but the proportion of the waste is generally not clear, which will cause the calorific value of the processed solid waste recycled fuel balls to vary greatly. The fuel balls with high industrial solid waste content have high combustion calorific value, while the combustion calorific value of light industrial and agricultural waste is low, which makes it difficult to measure their combustion efficiency. At the same time, when combustible solid wastes such as urban solid waste, industrial waste, and biomass are processed, if there are too many impurities in them, it will also affect their combustion calorific value, thereby reducing energy utilization efficiency. Therefore, the present application provides a solid waste recycled fuel ball and a processing method thereof. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a solid waste recycled fuel ball and a processing method thereof, which solves the problem that the existing solid waste recycled fuel balls are formed by processing combustible solid wastes such as urban solid waste, industrial waste, biomass, etc., but the proportion of the waste is generally not clearly defined, which results in a large difference in the calorific value of the processed solid waste recycled fuel balls. The fuel balls with a high industrial solid waste content have a high combustion calorific value, while the fuel balls with a low combustion calorific value of light industrial and agricultural wastes have a low combustion calorific value, which makes it difficult to measure their combustion efficiency. At the same time, when combustible solid wastes such as urban solid waste, industrial waste, biomass, etc. are processed, if there are too many impurities in them, their combustion calorific value will be affected, thereby causing a decrease in energy utilization efficiency.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a solid waste regeneration fuel ball, including industrial solid waste and light industrial and agricultural waste, wherein the mass ratio of the industrial solid waste to the light industrial and agricultural waste is 1:1;

[0009] Preferably, the processing method includes specifically: proportioning→mixing→drying→conditioning→feeding into molds→granulation→drying→inspection and packaging.

[0010] Preferably, the proportioning step is specifically:

[0011] Step 1: Use a batching scale to accurately weigh various raw materials to ensure accurate proportions, so that the mass ratio of industrial solid waste to light industrial and agricultural waste is 1:1;

[0012] Step 2: Using a pulverizer to crush the above raw materials into a particle size suitable for subsequent processing;

[0013] Step 3: Use a screening machine to screen the crushed raw materials and remove particles that do not meet the requirements.

[0014] Preferably, the mixing step specifically comprises: using a mixer to fully mix the raw materials processed in the proportioning step by means of rotational stirring.

[0015] Preferably, the drying step specifically comprises: preheating and drying the raw materials mixed in the mixing step by using a hot air furnace and natural cooling and ventilation.

[0016] Preferably, the conditioning step is specifically:

[0017] The raw materials are homogenized and matured using a homogenizer and a maturation chamber to further improve their physical and chemical properties.

[0018] Preferably, the step of feeding into the mold is specifically as follows:

[0019] Step 1: Use a feeder to feed the raw materials processed in the tempering step into the mold;

[0020] Step 2: After the raw materials are fed into the mold, they need to be vibrated using a vibration table to fill them tightly in the mold.

[0021] Preferably, the granulation step is specifically:

[0022] The material is subjected to pressure in the die, extruded through the holes of the die, and formed into a ball during the extrusion process.

[0023] Preferably, the drying step specifically includes: using a dryer to dry the granulated fuel balls by heating and ventilation to remove excess moisture and volatile substances.

[0024] Preferably, the inspection and packaging step specifically includes: conducting quality inspection on the dried fuel balls, including calorific value, ash content, and moisture indexes, and packaging and storing the fuel balls that have passed the inspection using a packaging machine.

[0025] The present invention discloses a solid waste regeneration fuel ball and a processing method thereof, which has the following beneficial effects:

[0026] 1.

By optimizing the fuel ratio and improving the production process measures, the calorific value of the fuel ball can be further improved to meet the demand for high-quality energy in more fields.

[0027] 2. The solid waste recycled fuel ball and its processing method, in the process of processing the fuel ball, the raw materials processed in the tempering step are fed into the mold by a feeder; after the raw materials are fed into the mold, a vibration table is used to vibrate them to make them tightly filled in the mold, the material is subjected to pressure in the mold, extruded through the holes of the mold, and formed into a spherical shape during the extrusion process, so that fuel balls with moderate particle size can be obtained. The fuel balls have a large combustion surface area, which is conducive to the combustion reaction, thereby improving the calorific value. Too large or too small particles are not conducive to combustion, which may lead to a decrease in calorific value.

[0028] 3.

[0053] Particularly disclosed, the step of feeding into the mold is specifically as follows:

[0054] Step 1: Use a feeder to feed the raw materials processed in the tempering step into the mold;
