Description

Technical Field

[0001] This invention belongs to the field of thermal battery manufacturing technology, and specifically relates to a thermal battery waste treatment system. Background Technology

[0002] The waste generated after the production of thermal batteries mainly consists of FeS2, CoS2, LiCl, KCl, LiF, LiCl, LiBr, MgO, LiSi, LiB, Fe, KClO4, Zr, BaCrO4, and asbestos paper. Among these, FeS2, CoS2, LiSi, LiB, Fe, KClO4, Zr, and BaCrO4 can undergo combustion reactions when exposed to fire. LiCl, KCl, LiF, LiCl, and LiBr react with water. MgO and asbestos paper do not react with either water or fire, but they will suspend in water. Therefore, the current method for treating thermal battery waste is to first treat it using pyrometallurgical methods, and then spray the waste gas from the pyrometallurgical treatment with an alkaline liquid. After the sprayed liquid evaporates, it is treated together with the waste from incineration as solid waste. Current treatment methods generally employ open-air, uncontrolled methods, requiring manual operation at each stage. If gas leaks during the treatment process, it can cause irreparable harm to the air and human health. Furthermore, in order to save manpower and resources, traditional methods involve centralized, unsafe disposal of the gas in large bags. This disposal method not only affects the efficiency of combustion but also poses a safety hazard to production. Summary of the Invention

[0003] To address the aforementioned problems, this invention aims to provide a thermal battery waste treatment system.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a thermal battery waste treatment system, including a waste conveying system and an incineration system. The incineration system is connected to a dust purification system in sequence through pipes. After the dust purification system, a first waste gas purification system, a second waste gas purification system, and a gas emission mechanism are connected in sequence through pipes. A human-machine operating system is also provided at the terminal of the equipment.

[0005] The incineration system is used for the incineration and destruction of waste. An ignition system is embedded on the side of the incineration system for igniting the waste.

[0006] Dust purification system for dust purification and filtration after incineration of waste materials from thermal batteries;

[0007] The first and second waste gas purification systems are used for the purification and treatment of waste gas generated after waste incineration.

[0008] Gas emission mechanisms are used for the emission of purified gases;

[0009] Pipelines are used for connecting various subsystems and for transporting waste gas;

[0010] The human-machine operating system is used for the control of the entire system.

[0011] The waste conveying system includes a conveyor chain, a variable frequency motor, and a fixed support. One end of the waste conveying system is a feeding port, and the other end is a feeding port. When the waste conveying system is running, the variable frequency motor drives the conveyor chain to send the waste from the feeding port to the feeding port, thereby feeding the waste into the incineration system.

[0012] The incineration system includes an incinerator with a ramp design at the inlet. When waste enters the incineration system, it slides down the ramp to the ignition zone. The incinerator is constructed of refractory bricks and refractory cement and can withstand temperatures above 1100℃.

[0013] The ignition system includes a high-pressure atomizing pump, a high-pressure electronic ignition device, and a combustion accelerant. The combustion accelerant is atomized under high pressure by the high-pressure atomizing pump, and then the combustion system is ignited by a remotely controlled electronic ignition device.

[0014] The combustion aid is diesel oil. During waste treatment, once the first bag of waste enters the incineration system, it only needs to be ignited once using the ignition system. After that, no further ignition is required.

[0015] The dust purification system includes a flame purifier, a gas cooler, and a pulse-jet bag filter. After the waste is incinerated by the incineration system, the high-temperature exhaust gas enters the flame purifier and gas cooler through pipelines for flame filtration and gas cooling, and finally enters the pulse-jet bag filter for dust purification.

[0016] The pipes connecting the dust purification system and the incineration system are longer than those connecting other systems to prevent the high temperatures from the incineration system from damaging the pipes and the dust purification system.

[0017] The first and second waste gas purification systems include a spray tower and a spray cabinet. The spray tower contains a weakly alkaline liquid with a pH value of 10 to purify sulfur oxides and nitrogen oxides in the waste gas. The spray cabinet contains a neutral liquid to further purify the purified waste gas.

[0018] The gas emission mechanism includes a fan, which uses negative pressure to draw out the gas purified by the second waste gas purification system and discharge it into the atmosphere. The gas emission mechanism is the power mechanism for transporting waste gas.

[0019] The human-machine operating system mainly includes a PLC controller, a human-machine interface, and electrical control components, which perform logical control and human-machine interaction on the above-mentioned equipment subsystems.

[0020] Compared with the prior art, the present invention has the following advantages:

[0021] 1. The treatment of thermal battery waste has been changed from an uncontrollable open-air treatment method to an indoor controllable treatment method, which adopts remote operation of electronic system, increasing safety and improving production efficiency.

[0022] 2. The waste gas after waste treatment is changed from being discharged directly without purification to being treated by a purification system. A single pipeline runs through the entire system, and the waste gas is discharged only after it meets the standards.

[0023] 3. The waste disposal method has been changed from centralized disposal in large bags without safety measures to phased feeding, making the disposal safe and controllable. Attached Figure Description

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. However, it should not be construed that the scope of the subject matter of the present invention is limited to the following embodiments. All modifications, substitutions and alterations made based on ordinary technical knowledge and common practices in the art without departing from the above-described technical concept of the present invention are included within the scope of the present invention.

[0028] Reference Figure 1 A thermal battery waste treatment system includes a waste conveying system 1 and an incineration system 2. The incineration system 2 is connected to a dust purification system 3 via a pipe 7. Following the dust purification system 3, a first exhaust gas purification system 4, a second exhaust gas purification system 5, and a gas emission mechanism 6 are connected to it via pipe 7. A human-machine interface 8 is also installed at the end of the system. The incineration system 2 is used for waste incineration and destruction. An ignition system is embedded on the side of the incineration system 2 for igniting the waste. The dust purification system 3 filters and purifies the dust generated after thermal battery waste incineration. The first exhaust gas purification system 4 and the second exhaust gas purification system 5 are used for purifying the exhaust gas generated after waste incineration. The gas emission mechanism 6 is used for the emission of purified gas. The pipe 7 is used for connecting the various subsystems and conveying exhaust gas. The human-machine interface 8 is used for controlling the entire system.

[0029] First, waste is conveyed from the waste conveying system 1 to the inlet via a conveyor chain driven by a variable frequency motor. The waste is conveyed in multiple batches, with each batch weighing 1 kg, and fed into the incineration system 2. Once inside the incinerator in incineration system 2, the waste slides down a ramp to the ignition zone. The incinerator is constructed of refractory bricks and refractory cement, capable of withstanding temperatures above 1100℃. When the first bag of waste enters the incinerator, the ignition system 3 next to the incinerator is activated. Diesel fuel is atomized under high pressure by a high-pressure atomizing pump and then ignited using a remotely controlled electronic ignition device. At this point, combustion begins in the incinerator.

[0030] Secondly, the high-temperature exhaust gas after combustion enters the flame purifier and gas cooler through pipe 7 for flame filtration and gas cooling, and finally enters the pulse-jet bag filter for dust purification. The pipe 7 connecting the dust purification system 3 and the incineration system 2 is longer than the connection length between other systems to prevent the high temperature from the incineration system 2 from damaging the pipe 7 and the dust purification system 3.

[0031] Then, the gas exiting the dust purification system 3 enters the first waste gas purification system 4 and the second waste gas purification system 5 in sequence. The spray tower contains a weakly alkaline liquid with a pH value of 10 to purify the sulfur oxides and nitrogen oxides in the waste gas, while the spray cabinet contains a neutral liquid to further purify the purified waste gas.

[0032] Finally, the gas emission mechanism 6 includes a fan that uses negative pressure to draw the purified gas from the second exhaust gas purification system 5 out and discharge it into the atmosphere. The gas emission mechanism 6 serves as the power mechanism for exhaust gas transport. Throughout the process, the human-machine interface 8 performs logical control and human-machine interaction for the various subsystems mentioned above. It mainly includes a PLC controller, a human-machine interface, and electrical control components.

[0033] This system can automatically transfer, ignite, and incinerate waste thermal batteries, as well as purify the waste gas generated after incineration. It achieves separation of humans and machines in the treatment of waste thermal batteries, improving the safety and environmental friendliness of waste thermal battery treatment.

[0034] The thermal battery waste treatment system provided by this invention has been described in detail above. Specific examples have been used to illustrate the structure and working principle of this invention. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this invention. It should be noted that those skilled in the art can make several improvements and modifications to this invention without departing from the principles of this invention, and these improvements and modifications also fall within the scope of protection of the claims of this invention.
