preparation example Construction

[0056] The method for preparing artificial coal of the present invention comprises steps:

[0057] (i) mixing 30-75 parts by weight of organic sludge and 10-40 parts by weight of swill to form a first mixture;

[0058] (ii) drying the first mixture obtained in step (i) so that the water content is lower than 30 wt% of the weight of the first mixture, and then adding 5-20 parts by weight of waste engine oil and / or waste rubber to form a second mixture;

[0059] (iii) shaping the second mixture to form solidified artificial coal.

[0060]In the preparation method of the present invention, in step a, the organic sludge and slops are semi-dried first, so that the water content is less than 60%, more preferably, the water content is 10-15%.

[0061] The sludge is semi-dried first, and then fully dried after discarding part of the water. In this way, the production capacity of the full-drying equipment is significantly improved, and the dust is significantly reduced, which increase...

Embodiment 1

[0076] Production of manufactured coal 1

[0077] 1. Beating 20 kg of slops to separate pulp and slag to obtain swill;

[0078] 2. The slag is mixed with 60 kg of organic sludge and semi-dried so that the water content is lower than 60%;

[0079] 3. Add 1 kg of wood flour to the above mixture;

[0080] 4. The mixture obtained in step 3 is mixed in a mixing cylinder and then dried with fluidized bed drying equipment;

[0081] 5. Carry out oil-water separation to the slurry gained after slurry slag separation in step 1, add the mixture (mixing ratio is 1: 1) of 10 kilograms of waste engine oils and waste rubber powder (calorific value 9859) in the oil of gained, add The dried product obtained in step 4 is mixed in the oil distribution cylinder;

[0082] 6. Pack artificial coal after briquettes are formed, and the water content is 15%.

[0083] According to laboratory testing, the combustion value of the prepared artificial coal is 5270 kcal.

Embodiment 2

[0085] Produce artificial coal 2

[0086] 1. Beating 10 kg of slops to separate pulp and slag to obtain swill;

[0087] 2. The slag is mixed with 30 kg of organic sludge and semi-dried to make the water content less than 60%;

[0088] 3. The mixture obtained in step 2 is mixed in a mixing cylinder and then dried with fluidized bed drying equipment;

[0089] 4. carry out oil-water separation to the slurry obtained after pulp slag separation in step 1, add 5 kilograms of waste engine oil, waste rubber powder (calorific value 7619) and waste plastic powder (calorific value 6381) in the oil of gained Mixture (the mixing ratio is 1:1:0.2), then add the dried product obtained in step 3, and mix in the oil distribution cylinder;

[0090] 5. After the briquettes are formed, the artificial coal is packaged, and the water content is 12%.

[0091] Through laboratory testing, the combustion value of the artificial coal prepared in the embodiment is 5100 kcal.

Abstract

This invention relates to a method for preparing artificial coal that can produce thermal energy. The artificial coal comprises: organic sludge 30-75 parts, hogwash/residual leaves/waste sawdust 10-40 parts, and waste engine oil/waste plastic/waste rubber 5-20 parts. The artificial coal adequately utilizes a variety of wastes, and is environmentally friendly.

Description

technical field [0001] The invention relates to the field of energy, in particular to artificial coal capable of generating thermal energy and a preparation method thereof. Background technique [0002] According to reports, my country's per capita recoverable energy reserves are far below the world average. In 2000, the per capita oil reserves were only 2.6 tons, the per capita natural gas recoverable reserves were 1074 cubic meters, and the per capita recoverable coal reserves were 90 tons, which were 11.1 of the world average. %, 4.3% and 55.4%. [0003] Since 1980, my country's total energy consumption has increased by about 5% per year, which is nearly three times the world's average growth rate. There is already a huge gap between China's energy reserves and its development needs in the next few decades, and this gap will become wider and wider. Some experts have calculated that my country's domestic energy gap will exceed 100 million tons of standard coal in the earl...
