Problems solved by technology

[0003] In the garbage recycling industry chain, for those low-value recyclables, there is no back-end processing and utilization chain to undertake the front-end resource recovery, and there is also a lack of corresponding support policy support, because the environmental attributes of low-value recyclables are far greater. Because of its economic valu

Embodiment Construction

[0032] The invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0033] refer to figure 1 , the present invention provides a low-value and bulky domestic solid waste treatment method, specifically, comprising the following steps:

[0034] (1) Crushing and iron removal: put large solid waste into the crusher for crushing treatment, the particle size after crushing is less than 12cm, and remove iron through a magnetic separator to obtain iron removal particles;

[0035] (2) Deoxygenation: The particles in (1) are compressed and pumped through a deoxygenation equipment to form compressed blocks, which are transported to the next step;

[0036] (3) Cracking: Introduce natural gas into the cracking furnace, add the lumps from the previous step, and crack at a temperature of 550°C to 700°C, preferably 600°C, to obtain solid phase residue and gas phase product respectively; the obtained solid phase residue is used as ra...

Abstract

The invention discloses a low-value large solid waste treatment method and device. The treatment method comprises smashing and iron removal, deoxidation, pyrolysis and gas-oil phase separation. The treatment device comprises a solid waste supply system, a smashing and iron removal system, a belt feeding machine, deoxidation equipment, a pyrolysis furnace and a recovery system, which are connected in sequence. According to the device and the method provided by the invention, low-value large solid waste, especially foam-containing waste, such as abandoned desks, chairs, stools and sofas, is treated by means of smashing, carbonization and pyrolysis, so that at a collection station of low-value large solid waste, the problems about quantity reduction, harmlessness and resource utilization can be solved, and meanwhile the problems about collecting and transporting the waste separately and finally treating the waste separately are solved. Therefore, the problem that waste is classified at first and then is combined in waste classification is solved from the source, and the costs of waste landfill and incineration are greatly saved.

Description

technical field [0001] The invention belongs to the field of environmental protection, and in particular relates to a method and device for treating low-value and large-sized domestic solid waste. Background technique [0002] The so-called large domestic solid waste refers to the weight of more than 5kg or the volume of more than 0.2m 3 And large and durable solid waste such as waste furniture, office appliances, waste electrical appliances, packing boxes, and baskets with a length of more than lm. Bulky domestic solid waste includes many types, ranging from household appliances such as microcomputers, refrigerators, and televisions, down to tables, chairs, stools, sofas, etc. Low-value and large-sized fixed waste refers to discarded furniture, Forest wood and other waste materials. The types of low-value bulky domestic solid waste are closely related to the economic level. The more developed the economy, the more types there will be. At the same time, the faster the rene...
