Embodiment

[0066] Weigh raw materials (kg) according to the following proportioning ratio:

[0067] Household garbage 65, deodorant 3, ignition agent 3, combustion aid 20, sulfur-fixing, hydrogen chloride-fixing substance 4, anti-corrosion, adhesive 5.

[0068] The specific ratio of the additives is as follows:

[0069] Deodorant: 2% bleaching powder, 0.5% sodium hypochlorite, 0.5% permanganate;

[0070] Ignition agent: 0.8% ammonium nitrate, 0.6% ammonium carbonate, 0.8% calcium nitrate, 0.6% sodium chloride, 0.2% zinc powder;

[0071] Combustion aid: 15% coal gangue, 5% coke powder;

[0072] Sulfur-fixing and hydrogen chloride-fixing substances: prepare 2% calcium oxide, 1% sodium hydroxide, 0.6% ammonium carbonate, and 0.4% others according to the proportion;

[0073] Bonding and preservatives: 3% water glass, 1% sodium propionate, 1% sodium diacetate.

[0074] The preparation method of garbage recycled coal products is as follows:

[0075] 1. Firstly, put the municipal solid was...

Abstract

The invention relates to a living garbage renewable coal product and a preparation method thereof. The product comprises: 65 percent to 70 percent of living garbage, 15 percent to 20 percent of comburent, 3 percent to 6 percent of deodorant, 3 percent to 7 percent of ignition agent, 2 percent to 5 percent of sulfur fixing and hydrogen chloride fixing substances, 1 percent to 2 percent of preservative and 2 percent to 3 percent of adhesive. The preparation method comprises the following steps: the garbage is collected to all the additive components are prepared to the scratch, the vibration selection and the magnetic selection pre-treatment are carried out, thereby removing coarse visible inert materials and iron and steel metals and then carrying out the coarse breaking of the garbage by using a coarse breaker to the coarsely broken garbage is extruded to carry out the dehydration by using a high-speed rotary extruder, the deodorant and the sulfur fixing and chloride fixing substances are added for even mixing to the high-temperature drying by a tunnel kiln is carried out to the fine breaking is carried out after the drying, the ignition agent, the comburent, the preservative and the adhesive are added to the even mixing with the garbage particles after the fine breaking is carried out to the extrusion forming is carried out. The product and the preparation method can ensure the urban living garbage to achieve the purposes of resourceful treatment, harmless treatment and industrialization.

Description

technical field [0001] The invention relates to an environment-friendly solid waste treatment technology, in particular to a domestic garbage regenerated coal product and a preparation method thereof. Background technique [0002] With the acceleration of urbanization and the improvement of people's living standards, the problem of domestic waste urgently needs to attract the attention of the city government. my country's municipal solid waste treatment started in the 1980s. Before 1990, the national urban waste disposal rate was less than 2%. After entering the 1990s, the level of municipal solid waste treatment has been continuously improved. According to the statistics of 661 cities across the country in 2005, the volume of domestic garbage removal was 156 million tons. However, due to the problems of funds, technology, and sites, many cities have not been able to fundamentally solve the problem of urban waste disposal. Every day, tens of thousands of tons of waste can...
