Description

Technical Field

[0001] The utility model relates to the technical field of chemical waste treatment, in particular to a chemical waste harmless treatment device. Background Art

[0002] Chemical waste harmless incineration is a process that converts hazardous chemical waste into harmless substances through high-temperature incineration. This method is mainly applicable to organic waste that cannot be recycled or chemically treated. During the incineration process, the waste is sent to a specially designed incinerator. Under high temperature conditions, organic matter is oxidized and decomposed into basic molecules such as carbon dioxide and water, while inorganic pollutants such as heavy metals remain in the form of ash, which then needs further treatment to ensure safe disposal.

[0003] Although the existing chemical waste incineration treatment technology has achieved waste reduction and disinfection to a certain extent, there are still many problems, resulting in its inefficiency and environmental protection. First, the design and technical level of traditional incinerators are limited, resulting in incomplete incineration, generating a large amount of smoke, fly ash and harmful gases, especially the emission of persistent organic pollutants such as dioxins, which have long-term hazards to human health and the environment. Secondly, the energy consumption in the incineration process is large, and there is a lack of effective energy recovery mechanism, which makes the economic benefits of the whole process low. Furthermore, for chemical waste with certain special components, such as chlorine-containing and sulfur-containing compounds, incineration treatment may produce more harmful by-products, increasing the difficulty of subsequent treatment.

An exhaust pipe 13 is connected to the top of the incinerator 2, and an exhaust end of the exhaust pipe 13 is fixedly connected to a waste gas treatment tower 14, and an exhaust port is provided on the top of the waste gas treatment tower 14.

[0021] like Figure 1 , Figure 5 and Figure 6As shown, it also includes a connecting shell 11, a water storage tower 12, a water receiving bucket 15, a filter screen 16, an activated carbon placement plate 17 and a sprinkler 18. The top of the incinerator 2 is fixedly connected to the connecting shell 11, the top of the connecting shell 11 is fixedly connected to the water storage tower 12, the exhaust pipe 13 is spirally arranged inside the water storage tower 12, the top of the water storage tower 12 is fixedly connected to a water inlet pipe, the bottom of the outer wall of the water storage tower 12 is fixedly connected to a water outlet pipe, and the exhaust gas treatment tower 14 is fixedly connected to two filter screens 16, the mesh number of the upper filter screen 16 is greater than the mesh number of the lower filter screen 16, thereby realizing multi-stage filtration Two activated carbon placing plates 17 are fixedly connected to the inside of the exhaust gas treatment tower 14, and activated carbon for purifying exhaust gas is placed on the activated carbon placing plates 17. The two activated carbon placing plates 17 are both located above two filter screens 16. A water receiving bucket 15 is fixedly connected to the bottom of the exhaust gas treatment tower 14, and a sewage outlet is provided on the outer wall of the water receiving bucket 15.

[0022] Initially, the sealing door 5 is in an open state away from the incinerator 2, and the locking assembly 6 is separated from the incinerator 2. When processing chemical waste, the chemical waste is temporarily placed on the top of the sealing door 5, and then the chemical waste is put into the ash partition board 3 from the feeding port. After the chemical waste is ignited, the sealing door 5 is rotated to make it vertical, and then the sealing door 5 is slid along the slide groove to approach the incinerator 2. The sealing door 5 is embedded in the incinerator 2 and the feeding port is closed. The locking assembly 6 is threadedly connected to the incinerator 2, and the locking assembly 6 is rotated to make it close to and squeeze the sealing door 5. The sealing door 5 can be fixed, and the sliding embedded sealing door 5 can improve the sealing performance of the treatment device, prevent the harmful gases generated by combustion from being continuously discharged into the atmosphere, and prevent the heat in the incinerator 2 from being lost to the outside, thereby ensuring the safety of the staff. The ashes after the chemical waste is burned out fall between the left and right inclined plates 101 through the through groove, and the inclined plates 101 can concentrate the ashes. When the ashes in the incinerator 2 need to be cleaned, the movable door 102 is opened, and then the ashes are shoveled out with tools, and the high-temperature waste generated by the incineration is The exhaust gas is discharged from the exhaust pipe 13. The high-temperature exhaust gas heats the exhaust pipe 13. The water in the water storage tower 12 can absorb the heat of the exhaust pipe 13 and reuse the high-temperature exhaust gas, which can reduce the factory's demand for additional heat sources, such as coal-fired or gas-fired boilers, thereby reducing energy consumption and greenhouse gas emissions. The exhaust gas is discharged from the exhaust end of the exhaust pipe 13 into the bottom of the exhaust gas treatment tower 14. The exhaust gas moves upward from the bottom of the exhaust gas treatment tower 14. Multiple filter screens 16 and activated carbon placement plates 17 filter the exhaust gas, and finally it is discharged from the exhaust port on the top of the exhaust gas treatment tower 14. The filter screen 16 can filter large particles in the exhaust gas. The activated carbon on the activated carbon placement plate 17 can absorb harmful substances in the exhaust gas to prevent the exhaust gas from polluting the environment. After using it for a period of time, use a sprayer 18 to spray water to clean the filter screen 16 to prevent the filter screen 16 from being blocked by large particles and causing the exhaust gas to be unable to be discharged normally from the exhaust port. The cleaned sewage falls into the water receiving bucket 15 for storage, and the sewage in the water receiving bucket 15 is discharged through the sewage outlet.
