Embodiment Construction
[0044] Below in conjunction with each accompanying drawing, the present invention is described in detail.
[0045] Such as figure 1 As shown, a method for disposing of urban and rural solid waste by a cracking gasification system 19 includes the following steps:
[0046] 1) Receive the domestic waste 1, mix and homogenize the domestic waste 1, filter out the leachate and crush it to obtain the first material to be dried, and transport the leachate obtained from the domestic waste 1 to the domestic waste sewage treatment system 12 for treatment ;
[0047] receiving the kitchen waste 2, draining the kitchen waste 2 to obtain leachate, and then crushing the kitchen waste 2 to obtain the second material to be dried;
[0048] Receive the catering waste 3, drain the catering waste 3 to obtain leachate, then sort the catering waste 3, and sort out the food waste 3 that is larger than the set value to obtain the third material to be dried, and the rest enter the three-phase extracti...

The present application discloses a method for disposing of urban and rural solid waste by a pyrolysis gasification system. 2) The three-phase oil extraction system works to obtain the material to be dried; 3) Each material to be dried enters the bin-type biological drying unit through the distribution system for drying operation; 4) After drying The final mixture enters the sorting unit; 5) The sieved soil and light combustibles selected in step 4) are transported to the cracking gasification system for cracking and gasification operation; 6) The high temperature combustible gas obtained by the purification system is used for Purify. This application focuses on the disposal of urban and rural domestic waste, and co-disposes of waste oil, catering waste and kitchen waste. Among them, the solid residues from catering, kitchen waste, and waste oil are bio-dried together with domestic waste, and all materials have been effectively recycled.
Description
technical field [0001] The invention relates to the field of solid waste treatment, in particular to a method for disposing of urban and rural solid waste in a cracking gasification system. Background technique [0002] At present, the difficulties in urban and rural solid waste disposal are as follows: [0003] 1. The amount of garbage provided is low. Taking domestic waste as an example, the amount of domestic waste in general counties is below 300t / d, and the total amount of catering, kitchen waste, and gutter oil is below 50t / d. Implementation requires a large amount of investment. [0004] 2. During the disposal of catering, kitchen waste, and gutter oil, there will be a large amount of solid residue that needs to be transported abroad for disposal, which greatly increases the investment cost. Contents of the invention [0005] Aiming at the above problems, the present invention overcomes at least one deficiency, and proposes a method for disposing of urban and rur...
