Embodiment 1

[0037] After sending the special sealed container for food waste to the disposal point, refer to figure 1 , do the following:

[0038] 1) Preprocessing

[0039] Food waste is weighed and measured before sorting. Sorting uses twisted cages to remove plastic bags (cloth) and large debris for subsequent crushing. The rest of the sorted food waste is crushed with a reamer and screened by a vibrating screen (Guosheng DZSF520 type) to remove impurities, and the food waste with a particle size of 10mm or less is obtained, and the removed impurities are landfilled.

[0040] After removing impurities, the food waste with a particle size of 10mm or less is heated to 80°C, kept warm for 20 minutes, and then enters the three-phase separation equipment Fuller LW-350 horizontal spiral sedimentation centrifuge for deoiling, separating oil, water, Slag. The water separated by deoiling enters the wastewater treatment system, the grease is used as fuel oil raw material, and the residue after...

Embodiment 2

[0049] After sending the special sealed container for food waste to the disposal point, refer to figure 1 , do the following:

[0050] 1) Preprocessing

[0051] Food waste is weighed and measured before sorting. Sorting uses twisted cages to remove plastic bags (cloth) and large debris for subsequent crushing. The rest of the sorted food waste is crushed with a reamer and screened by a vibrating screen (Guosheng DZSF520 type) to remove impurities. The food waste with a particle size of 10mm or less is obtained, and the removed impurities are buried.

[0052] After cleaning, the food waste with a particle size of 10mm or less is heated to 80°C, and the briquette fuel obtained in Example 1 is burned with a biomass burner (Zinhai H60 type), and the combustion flue gas is used for heating.

[0053] After 20 minutes of heat preservation, it enters the three-phase separation equipment Fuller LW-350 horizontal spiral sedimentation centrifuge for deoiling, and separates oil, water a...

Abstract

The invention provides a method for preparing briquettes fuel from deoiled kitchen waste. Specifically, the method comprises the steps of 1) pre-processing; 2) deep dewatering; 3) hot air drying; 4) shaping. The method has an advantage of making full use of energy of organic matters in the kitchen waste to prepare fuel oil from grease and prepare briquettes fuel from solid slag, thus achieving a high energy utilization rate; the method, which prepares the solid slag into briquettes fuel, can avoid solid phase landfill and guarantee thorough reduction. The briquettes fuel prepared by the method is applicable to heat supply in pre-processing and hot air drying steps, and can realize cyclic utilization.

Description

technical field [0001] The invention relates to solid waste treatment technology, in particular to a method for preparing briquette fuel from kitchen waste after deoiling. Background technique [0002] Food waste refers to food residues from restaurants, restaurants, unit canteens, and family daily life, commonly known as swill. The development of social economy, the acceleration of people's life rhythm and the increase of floating population have all led to the rapid development of the catering industry, resulting in a large amount of food waste. [0003] In the past, the main outlets for food waste were: first, it was fed to pigs without any treatment by urban and rural pig farmers, and thousands of "garbage pigs" were slaughtered; Sold in oil. This problem of disorderly management and arbitrary disposal has seriously affected the health of residents and the quality of the environment. As the key to waste disposal, food waste has been paid more and more attention by the...
