Problems solved by technology

[0005] The characteristics of the equipment require that the garbage be sorted in advance. Due to the uncertainty of the garbage, the crusher cannot be satisfied with the presence of large metal objects and large stones in the garbage.
This kind of equipment is often caused by the downtime of the rotary cracking furnace during the cracking process due to the mixing of hard-to-break substances. The equipment itself is a large energy-consuming equipment, and the loss of a shutdown is relatively large.
Secondly, urban waste treatment does not allow downtime for too long, so this type of equipment is not widely used in China

[0046] The main body of the cracking equipment 2 is a body of furnace 9, a movable airtight door 10 is arranged on the body of furnace 9 connecting ...

Embodiment 2

[0054] The harmless classification-free solid waste pyrolysis method of this embodiment includes the following steps:

[0055] 1) The first stage: the solid waste loaded in the material basket 8 is placed in the cracking chamber of the cracking equipment 2, and the temperature is raised to 150° C., and the reaction time is xx hours;

[0056] 2) The second stage: heat up to 600°C, reaction time: xx hours; generate combustible gas, cracked gas and solid carbon powder;

[0057] 3) The third stage: discharge the oil-air mixture and solid powder after cooling.

[0058] Step 2) The resulting cracked gas is condensed through a chemical catalyst reaction to obtain a mixed oil including gasoline, diesel oil and heavy oil.

[0059] The combustible gas obtained in step 2) is recovered and introduced into the burner 13 to provide the heat source of step 1) and step 2).

Abstract

The invention discloses a harmless classification-free solid waste splitting decomposition device and splitting decomposition method. The splitting decomposition device comprises a feeding segment, a splitting decomposition device body and a discharging segment which are sequentially connected. The device comprises a bracket penetrating the feeding segment, the splitting decomposition device body and the discharging segment, and transmission rollers installed on the two sides of the bracket. The transmission rollers are meshed with a chain. A transmission motor drives chain wheels to rotate. The chain wheels drive the chain meshed with the chain wheels so that the transmission rollers can be driven to rotate. The splitting decomposition device body is a furnace body and is a closed space. A splitting decomposition chamber and a combusting chamber are arranged in the furnace body. The outer side of the portion, where the combustion chamber is located, of the furnace body is provided with a combustor, and a combustion gas outlet is led into the combustion chamber. A plurality of overheat steam pipelines are arranged in the splitting decomposition chamber. Overheat steam is led into the splitting decomposition chamber. An oil and gas inner pipeline is arranged on the top of the splitting decomposition chamber and is connected into a catalytic agent generator on the top of the splitting decomposition chamber. An outlet of the catalytic agent generator is connected with an oil and gas outer pipeline. Organic matter in waste is completely processed through high-temperature anaerobic splitting decomposition, the resource conversion rate is high, and waste is processed in a harmless, reduced and resourceful manner.

Description

technical field [0001] The invention belongs to the technical field of solid waste treatment, and in particular relates to a harmless classification-free solid waste pyrolysis device and a pyrolysis method. Background technique [0002] At present, landfill, incineration, cracking and other methods are used to deal with garbage in China. The existing domestic garbage cracking mostly uses rotary kiln cracking equipment. The limitations are: [0003] The rotary kiln can make the garbage go forward with the rotary kiln, but the whole operation process requires crushing and dehydration of the garbage. [0004] The crushing of garbage requires high-power motors, and the consumption of electric energy is very high. This is far from the requirements for the cost of garbage disposal and the requirement to ensure that the garbage disposal industry gradually gets rid of government subsidies. [0005] The characteristics of the equipment require that the garbage be sorted in advance. ...
