Description

Technical Field

[0001] This invention relates to the field of waste treatment equipment technology, specifically to a fully automated centralized waste treatment equipment and its treatment method. Background Technology

[0002] Fully automated centralized municipal solid waste processing equipment is a modern technological device for processing municipal solid waste, and is an ideal choice for solving waste disposal problems in modern cities. It can quickly and accurately classify municipal solid waste, and mainly consists of a conveying system, a sorting system, a collection system, and a control system.

[0003] For example, application number CN202110818868.2 discloses a centralized domestic waste treatment device. When an appropriate amount of domestic waste is poured into the frame, the drive mechanism is activated. The drive mechanism moves downward and contacts the trigger mechanism. The drive mechanism drives the trigger mechanism to operate, and the operation of the trigger mechanism makes the grid plate horizontal. The trigger mechanism continues to operate and drives the grid plate to move downward. The downward movement of the grid plate compresses the domestic waste. In this way, the domestic waste is convenient for subsequent treatment and occupies little space.

[0004] However, the above-mentioned device only compresses household waste to facilitate subsequent processing. When processing household waste, such as incinerating it, the compressed waste needs to be disassembled before incineration. Otherwise, it is not conducive to the incineration of the compressed waste. Furthermore, the above-mentioned device cannot process household waste in a fully automated manner.

[0011] Optionally, the regeneration mechanism includes a first oil-gas separator and a temperature heating sensor. The first oil-gas separator is connected to an oxygen-free chamber. The end of the first oil-gas separator away from the pyrolysis chamber is connected to a first reactor.

The pyrolysis chamber is connected to a sorting chamber, and the sorting chamber is connected to a carbon dioxide capture device. A second reactor is connected to one side of the first reactor, and a third reactor is disposed above the second reactor.

[0012] Optionally, the specific processing procedure is as follows:

[0013] a) The waste material is lifted to the first crushing mechanism through the feeding component for fine crushing to achieve the best processing effect. The crushed material is then transported to the second crushing mechanism for secondary fine crushing through the conveying component for further crushing. It is then stored in the storage and distribution chamber and then transported through the conveying component. During the conveying process, the waste material is heated evenly by the drying component to dry it to 90% before falling into the inner cavity of the first shell through the feed port.

[0014] b) First, the waste material is preheated in the preheating chamber and then falls into the oxygen-free chamber. The material is further dispersed by the conveying components to avoid affecting the pyrolysis effect due to the presence of moisture and oxygen. Then, the material falls into the inner cavity of the pyrolysis chamber. The waste material is placed in a medium-temperature pyrolysis environment of 400℃~600℃ to allow the molecules in the material to be converted and purified. After pyrolysis, the material undergoes a condensation (oil-gas separation) process. The first oil-gas separator separates the oil and gas. The fuel gas can be reused and the oil can be purified again. At the same time, the temperature heating sensor monitors the temperature of the pyrolysis environment in real time to ensure the stability of the pyrolysis process. The temperature heating sensor is also used to detect the drying and preheating temperatures.

[0015] c) The materials are then classified in the sorting chamber according to different material categories for subsequent processing and utilization. At the same time, the carbon dioxide capture equipment captures and stores the carbon dioxide generated during the pyrolysis process for subsequent processing and utilization. During the collection process, the second oil-gas separator separates the oil and gas. The fuel gas can be reused, and the oil can be purified. After carbon dioxide capture, an alkaline agent is added to the first reactor to convert it into water and nitrates. These two substances can be combined with carbon ash in the second reactor, and then granulated and naturally dried in the third reactor to finally form a usable product.

[0016] This invention provides a fully automatic centralized municipal solid waste treatment equipment and method, which has the following beneficial effects: The fully automatic centralized municipal solid waste treatment equipment and method feeds waste material into a crushing component for crushing and then performs fully automated processing to ultimately transform the waste material into usable products. This equipment adopts a fully automatic control system, which can realize the automatic collection, crushing and incineration of waste, improve the efficiency and quality of waste treatment, realize the harmless and resource utilization of waste, reduce the pollution of waste to the environment, and enable the equipment to utilize waste as a resource.

[0017] This fully automatic centralized municipal solid waste treatment equipment and its treatment method involves lifting the waste material through a feeding assembly to a first crushing mechanism for fine crushing to achieve the best treatment effect. The crushed material is then conveyed through a conveying assembly to a second crushing mechanism for secondary fine crushing. Since the distance between the first crushing roller and the second crushing roller in the first crushing mechanism is greater than the distance between the first crushing roller and the second crushing roller in the second crushing mechanism, the second crushing mechanism performs a fine crushing process. The waste material then enters a storage and distribution chamber for storage, and is then conveyed through a conveying assembly. During the conveying process, the waste material is uniformly heated by a drying assembly to dry it to 90% before falling into the inner cavity of the first shell through the feed inlet.

[0018] This fully automated centralized municipal solid waste treatment equipment and its treatment method preheats the waste material in a preheating chamber before it falls into an oxygen-free chamber. The material is then further dispersed using a conveying component to prevent the presence of moisture and oxygen from affecting the pyrolysis effect. The material then falls into the inner cavity of the pyrolysis chamber, where it is placed in a medium-temperature pyrolysis environment of 400℃~600℃, allowing the molecules in the material to be converted and purified. The pyrolyzed material undergoes a condensation oil-gas separation process, where the oil and gas are separated by a first oil-gas separator. The fuel gas can be reused, and the oil can be purified again. At the same time, a temperature heating sensor monitors the temperature of the pyrolysis environment in real time to ensure the stability of the pyrolysis process. The temperature heating sensor is also used to monitor the drying and preheating temperatures.

[0019] This fully automated centralized municipal solid waste treatment equipment and its treatment method classify materials in a sorting chamber, categorizing the pyrolysis materials according to different material categories for subsequent processing and utilization. Simultaneously, a carbon dioxide capture device captures and stores the carbon dioxide generated during the pyrolysis process for subsequent processing and utilization. During the collection process, a second oil-gas separator separates oil and gas. The fuel gas can be reused, and the oil can be purified. After carbon dioxide capture, an alkaline agent is added to the first reactor to convert it into water and nitrates. These two substances can combine with ash in the second reactor, and then granulation and natural drying are carried out in the third reactor to finally form a usable product.
