Household waste pretreatment device and pretreatment method adopting same

Abstract

The invention discloses a household waste pretreatment device and a pretreatment method adopting same and belongs to the technical field of waste pretreatment. The household waste pretreatment devicecomprises a base, an outer cylinder arranged on the upper side of the base, a plurality of far-infrared heating pipes arranged on the inner wall of the outer cylinder in an annular array, an annular baffle plate arranged on the inner side of the outer cylinder and an inner cylinder arranged on the inner side of the annular baffle plate; the outer cylinder and the base are connected through a plurality of supporting legs for supporting; the upper part of the outer cylinder is open; the lower part of the outer cylinder is closed; a water outlet is formed in the lower part of the outer cylinder;a water discharging valve is mounted on the water outlet; the annular baffle plate is connected with the supporting legs through a plurality of groups of heat conducting connecting rods; the upper part and the lower part of the annular baffle plate are open; the upper part of the inner cylinder is open; the lower part of the inner cylinder is closed; a plurality of water draining holes are uniformly formed in the circumferential surface of the inner cylinder. The household waste pretreatment device skillfully integrates smashing, drying and solid-liquid separation and is skillful in concept.

Description

technical field [0001] The invention relates to the technical field of garbage pretreatment, more specifically, to a domestic garbage pretreatment device and a pretreatment method thereof. Background technique [0002] With the improvement of my country's economic strength, people's living standards continue to improve, and the domestic waste generated by households and catering industries has also increased. At present, the amount of domestic waste generated has a geometric growth trend compared with decades ago. A large amount of domestic waste The emergence of the environment will inevitably bring great harm to the environment. However, my country's domestic waste treatment industry is in its infancy, and the method of anaerobic fermentation capacity treatment is one of the key points of future development. This technology is an advanced treatment of domestic waste. And now there are mature technological processes and schemes, but this technology has high requirements for t...

[0002] With the improvement of my country's economic strength, people's living standards continue to improve, and the domestic waste generated by households and catering industries has also increased. At present, the amount of domestic waste generated has a geometric growth trend compared with decades ago. A large amount of domestic waste The emergence of the environment will inevitably bring great harm to the environment. However, my country's domestic waste treatment industry is in its infancy, and the method of anaerobic fermentation capacity treatment is one of the key points of future development. This technology is an advanced treatment of domestic waste. And now there are mature technological processes and schemes, but this technology has high requirements for the pretreatment of domestic waste. The technical methods and equipment for the pretreatment of domestic waste mainly focus on solid-liquid separation, oil-water separation, and the collection of stench Gas, the effect of pretreatment directly affects the effect of subsequent anaerobic production capacity and the impact on the environment. Most of the existing domestic waste pretreatment methods and equipment are located in waste treatment plants or landfills, and their characteristics are basically Large-scale, energy-intensive and centralized processing

[0003] In the prior art, the pretreatment of domestic waste requires processing steps such as crushing, drying, and solid-liquid separation. However, there is no equipment in the prior art that can simultaneously achieve crushing, drying, and solid-liquid separation, and the above-mentioned The processing steps are combined, which is time-consuming and labor-intensive
