Description

Technical Field

[0001] This utility model relates to the field of solid waste treatment technology, specifically to a solid waste combustion pollution early warning device. Background Technology

[0002] Solid waste refers to solid, semi-solid, and gaseous items and substances placed in containers that are generated during production, daily life, and other activities and have lost their original utilization value or have been discarded or abandoned even if they have not lost their utilization value. It also includes items and substances that are included in waste management according to laws and administrative regulations, liquid waste that cannot be discharged into water bodies, and gaseous substances that cannot be discharged into the atmosphere and are placed in containers. Because they are often highly hazardous, they are generally classified into the solid waste management system. In the prior art, Chinese utility model application number CN202222789822.5 discloses a solid waste harmless combustion device, including a combustion chamber, a connecting groove at the upper end of the combustion chamber, and support plates symmetrically fixedly installed at the lower end of the combustion chamber. Sliding grooves are provided on the opposite ends of the two support plates. A flue gas chamber is fixedly installed at the upper end of the combustion chamber and is connected to the connecting groove. Inclined plates are symmetrically fixedly installed on the inner wall of the flue gas chamber. A support block is fixedly connected to the combustion chamber. A fan is fixedly installed at the upper end of the support block. A surrounding filter screen is fixedly installed on the side wall of the fan, located in the flue gas chamber. An outlet pipe is fixedly installed on the end of the fan away from the surrounding filter screen, allowing the flue gas to be fully mixed with the purification solution inside the purification chamber for purification. The purified flue gas is further filtered and adsorbed when passing through an activated carbon filter screen, and then discharged through a strip groove, resulting in better purification effect of the device during use. While the above-mentioned technical solutions can purify flue gas, solid waste combustion produces a large amount of harmful gases. Incomplete combustion of solid waste can cause the concentration of harmful gases to exceed the threshold. Since the device does not have an early warning structure, it cannot notify staff in a timely manner, which leads to the aggravation of pollution from solid waste combustion. Therefore, we need to propose a solid waste combustion pollution early warning device. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of this utility model are: This invention primarily utilizes the coordination between a flue gas channel, a first gas sensor group, a second gas sensor group, an early warning module, and a data acquisition unit. The first and second gas sensor groups monitor the gas composition during the solid waste combustion process in real time and transmit the detected signals to the data acquisition unit.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-3This utility model provides a technical solution: a solid waste combustion pollution early warning device, including an incinerator 1, a purification water tank 2 above the incinerator 1, a flue gas channel 3 between the purification water tank 2 and the incinerator 1, a gas collection hood 13 above the purification water tank 2, a first gas sensor group 16 inside the flue gas channel 3, a second gas sensor group 17 at the gas outlet of the gas collection hood 13, temperature sensors 18 in both the inner cavity of the flue gas channel 3 and the top of the incinerator 1, an early warning module 11 and a data acquisition unit 12 on one side of the purification water tank 2, and a processor 10 electrically connected to the early warning module 11 and the data acquisition unit 12 on one side of the incinerator 1; The first gas sensor group 16 and the second gas sensor group 17 both contain a variety of gas sensors, such as sulfur dioxide sensors, nitrogen oxide sensors, carbon monoxide sensors, particulate matter sensors, etc., which are used to monitor the concentration of various pollutants emitted during the combustion of solid waste in real time. The data acquisition unit 12 is used to collect real-time data from various sensors and perform preliminary signal amplification and analog-to-digital conversion to convert analog signals into digital signals for subsequent processing. The processor 10 performs in-depth analysis on the collected data and compares it with preset pollution thresholds. The processor 10 can also perform trend analysis on the data and predict the changing trend of pollution emissions.

[0016] The warning module 11 includes a speaker 111 and multiple sets of LED beads 112. The multiple sets of LED beads 112 are arranged at equal intervals. The speaker 111 and LED beads 112 can easily emit alarm sounds and flashing lights to remind staff to take appropriate measures.

[0017] The flue gas passage 3 includes an inlet pipe 31 connected to the incinerator 1. One end of the inlet pipe 31 is provided with a guide pipe 32. One end of the guide pipe 32 is located at the bottom of the inner cavity of the purification water tank 2. One end of the guide pipe 32 is provided with an exhaust pipe 33. Multiple sets of exhaust holes 34 are opened on the lower surface of the exhaust pipe 33. The flue gas passage 3 facilitates the introduction of the flue gas generated by waste combustion into the solution in the purification water tank 2, thereby facilitating the adsorption of harmful gases and dust in the flue gas by the solution and improving the purification effect of the flue gas.

[0018] A support frame 14 is installed at the top of the inner cavity of the purified water tank 2, and an activated carbon filter plate 15 is installed above the support frame 14. Inlet and outlet water pipes are installed on one side of the purified water tank 2. The activated carbon filter plate 15 can further filter the purified flue gas, thereby ensuring the safety of the discharged flue gas.

[0019] The incinerator 1 is provided with a waste inlet 6 and a ventilation unit 9 on the side adjacent to the processor 10. A baffle 7 is rotatably installed inside the waste inlet 6. A feed hopper 8 is provided at the feed end of the waste inlet 6. The ventilation unit 9 facilitates the supply of oxygen to the incinerator 1, thereby accelerating the incineration of waste. The waste is discharged through the feed hopper 8, and the baffle 7 can prevent waste from overflowing.

[0020] Two sets of support plates 4 are fixedly connected to the lower surface of the incinerator 1. A waste residue collection box 5 is set between the two sets of support plates 4. Both sides of the waste residue collection box 5 are provided with protruding strips. A sliding groove is opened on the opposite side of the two sets of support plates 4 for the protruding strips to slide. The waste residue collection box 5 can be easily pulled out by the protruding strips, thereby facilitating the collection and treatment of the waste residue.

[0021] The bottom of the incinerator 1 has multiple sets of perforations 19 arranged in a rectangular array to facilitate the falling of waste residue generated during waste combustion for collection.

[0022] During use, solid waste enters the incinerator 1 through the feed hopper 8 and waste inlet 6. The ventilation unit 9 provides oxygen for combustion. The waste residue produced by incineration falls into the waste residue collection box 5 below through the leakage hole 19 at the bottom of the incinerator 1. The waste residue collection box 5 can slide in the groove of the support plate 4 through the convex strip, making it easy to pull out and clean.

[0023] The flue gas generated by incineration enters the purification water tank 2 through the flue gas passage 3. The flue gas first passes through the air inlet pipe 31, then through the air guide pipe 32 into the bottom of the purification water tank 2, and finally exits through the exhaust hole 34 on the exhaust pipe 33, so that the flue gas can fully contact the water in the tank for preliminary purification. The activated carbon filter plate 15 on the top of the purification water tank 2 performs secondary filtration on the flue gas. The purified flue gas is discharged from the gas collection hood 13.

[0024] Throughout the process, the first gas sensor group 16 and the second gas sensor group 17 monitor the gas composition at the outlet of the flue gas channel 3 and the gas collection hood 13 in real time, respectively. The temperature sensor 18 monitors the temperature of the inner cavity of the flue gas channel 3 and the top of the incinerator 1. The data acquisition unit 12 collects the data from these sensors and transmits it to the processor 10.

[0025] The processor 10 compares and analyzes the received data with preset pollution and temperature thresholds. If the monitored data exceeds the threshold, the processor 10 controls the early warning module 11 to issue an early warning, the speaker 111 emits an alarm sound, and the LED beads 112 flash to remind staff to take measures to prevent pollution caused by the combustion of solid waste.
