Embodiment 1

[0038] A kind of domestic refuse processing method of embodiment one, such as figure 1 shown, including the following steps,

[0039]S1. Put the garbage into the dissolving furnace, feed the dissolving oil into the dissolving furnace, and the dissolving oil dissolves the organic matter in the garbage into the dissolving oil to form a mixed oil, and collects the volatilized organic gas;

[0040] S2. Send the above solid-liquid mixture into a solid-liquid separator for solid-liquid separation to obtain the remaining mixed oil and residual solid.

[0041] S3. Send the residual solid produced in step S2 into a pyrolysis furnace for pyrolysis to obtain fuel carbon and organic gas.

[0042] S4. The fuel carbon in step S3 is sent into the incinerator, and air is introduced into the incinerator to obtain heat and high-temperature waste gas. The heat is used to supplement the heat of the cracking furnace and maintain the stability of the pyrolysis temperature in the pyrolysis furnace....

Embodiment 2

[0056] Such as figure 2 As shown, the domestic waste disposal method comprises the following steps:

[0057] S1. Put the garbage into the melting furnace, first feed low-temperature dissolved oil into the melting furnace, and the low-temperature dissolved oil dissolves the organic matter in the garbage into the low-temperature dissolved oil to form a low-temperature mixed oil, and collects volatile organic gases;

[0058] After the low-temperature mixed oil is discharged into the low-temperature heat exchanger for heating, the low-temperature mixed oil is returned to the melting furnace, and after a certain period of time, the low-temperature mixed oil in the melting furnace is discharged to the low-temperature heat exchanger and another melting furnace , and during the cycle, collect the organic gas produced.

[0059] Then feed the medium-temperature dissolved oil into the dissolution furnace, which dissolves the organic matter in the garbage into the medium-temperature dis...

Embodiment 3

[0078]In this embodiment, on the basis of Embodiment 1 or Embodiment 2, domestic waste is sent to the drying furnace intermittently after preliminary sorting and crushing to dry, and the dried waste and turbid steam are obtained, and the dried waste is sent into In the dissolution furnace, the turbid steam is sent to the steam purification device for purification. Waste heat recovery is performed on the steam purified by the steam purification device to obtain a product including condensed water.

Abstract

The invention relates to the technical field of garbage treatment, in particular to a household garbage treatment method. The method comprises following steps that garbage is fed into a dissolving furnace, dissolving oil is led into the dissolving furnace, organic matter in garbage is dissolved into dissolving oil and / or grease generated through heating and decomposing of the organic matter through dissolving oil is blended into the dissolving oil to form mixed oil, and volatile organic gas is collected; a solid-liquid mixture is fed into a solid-liquid separator to be subject to solid-liquid separation, and remaining mixed oil and residual solids are obtained; the generated residual solids are fed into a cracking furnace to be subject to high-temperature cracking, and fuel carbon and organic gas are obtained; the technical problem that when an existing product carries out pyrolysis on household garbage, the pyrolysis temperature higher than the garbage resistant to high temperature is adopted to carry out pyrolysis on the garbage resistant to low temperature, and energy is wasted is solved, and the household garbage treatment method can reduce energy consumption during household garbage pyrolysis.

Description

technical field [0001] The invention relates to the technical field of garbage disposal, and more specifically, relates to a domestic garbage disposal method. Background technique [0002] With the rapid development of economy, the continuous growth of population and the improvement of people's living standards, the generation of domestic waste has also increased sharply, which has caused a great burden on the environment. There are many methods of garbage disposal, such as landfill, composting and incineration, which are relatively mature methods. Garbage pyrolysis treatment has attracted widespread attention due to its high energy recovery rate and low pollution. The pyrolysis method will become a very promising garbage treatment method to replace traditional garbage treatment methods. Biomass pyrolysis (also known as pyrolysis or cracking), usually refers to the process in which biomass is heated and heated to cause molecular decomposition to produce coke, condensable li...
