It should also be understood that terms defined in general dictionaries should be interpreted as having meanings consistent with their meanings in the context of the relevant technology, and should not be interpreted in an idealized or extremely formal sense, unless explicitly defined herein.

[0030] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0031] When producing or using hazardous chemicals, some solid or liquid hazardous chemicals will be produced. The volatilization of these hazardous chemicals will produce harmful waste gas. When disposing of harmful waste gas, not only emission reduction is required, but also the cost of disposing of hazardous chemical waste will be increased.

[0032] Based on this, the utility model aims to provide a hazardous chemical waste collection device, the gaseous hazardous chemicals collected by which are suitable for high-concentration waste gas treatment equipment, which can reduce the operating energy consumption of the waste gas treatment equipment and reduce the emission of solid and liquid hazardous chemical wastes.

[0033] refer to Figure 1 and Figure 2 In some embodiments, the hazardous chemical waste collection device includes a barrel body 1, a cover plate 2 and a connecting pipe 3.

[0034] The barrel body 1 is formed with a containing cavity and an open end, and the containing cavity is configured to contain solid or liquid hazardous chemicals.

[0035] The cover plate 2 is arranged at the open end, and an exhaust area is arranged on the cover plate 2, and a plurality of first holes 21 are arranged in the exhaust area. The plurality of first holes 21 form a filter mesh structure in the exhaust area.

[0036] The first end of the connecting pipe 3 is connected to the exhaust area to enclose the plurality of first holes 21, and the second end of the connecting pipe 3 is configured to be connected to a pipeline of an exhaust gas treatment device so that the exhaust gas generated by the volatilization of hazardous chemicals can be burned through the exhaust gas treatment device.

[0037] The aperture of the first hole 21 is much smaller than the diameter of the connecting pipe 3. A plurality of first holes 21 are arranged in the exhaust area, which is beneficial to exhausting gas and forming a filter part in the exhaust area to prevent solid matter of a certain volume from entering the exhaust gas treatment equipment through the first holes 21.

[0038] In the above embodiment, the accommodating cavity of the barrel body 1 is used to accommodate solid or liquid hazardous chemicals, providing space for the volatilization of solid or liquid hazardous chemicals. The waste gas generated by the volatilization of the hazardous chemicals is discharged through the multiple first holes 21 on the cover plate 2, and is collected through the connecting pipe 3 and sent to the waste gas treatment equipment for combustion treatment. It is easy to operate, low in cost, can reduce the emission of hazardous chemicals, and protect the environment.

[0039] Exhaust gas treatment equipment often uses direct combustion technology, which heats the exhaust gas to 800°C or higher to oxidize and decompose the organic components in the exhaust gas into harmless carbon dioxide and water vapor. This method can effectively purify the concentration of 1.8g / m 3 Up to 6g / m 3 The purification efficiency of the exhaust gas within the specified range is as high as over 99%, which is particularly suitable for treating high-concentration organic pollutants.

[0040] Since the exhaust gas treatment equipment needs to heat the exhaust gas to 800℃ or higher, the energy consumption is relatively large, but the exhaust gas treatment equipment has the ability to self-maintain operation. That is to say, when the exhaust gas treatment equipment is treating high-concentration exhaust gas, it can use the exhaust gas as its own fuel source, greatly reducing the dependence on external fuel gas, thereby reducing energy consumption and reducing operating costs. However, if the exhaust gas concentration is lower than 1.8g / m 3 , the self-sustaining mechanism of the exhaust gas treatment equipment is difficult to maintain, and additional fuel gas must be added to ensure that the purification process continues, which leads to unnecessary consumption of energy and increased costs.

[0041] Based on this, the hazardous chemical waste collection device provided in the embodiment of the utility model can collect the waste gas generated by the gasification of hazardous chemicals, and send the waste gas to the waste gas treatment equipment. It can not only effectively treat the waste gas through the waste gas treatment equipment, reduce the emission of harmful gases, and protect the environment, but also provide the waste gas treatment equipment with high-concentration waste gas as fuel, so that the waste gas treatment equipment has a self-sustaining operation state, reduce the energy consumption and cost of the waste gas treatment equipment, and improve the economy.

[0042] In some embodiments, the hazardous chemical waste collection device further comprises a fan, which is arranged on a pipeline connecting the connecting pipe 3 and the waste gas treatment device. The waste gas generated in the barrel body 1 is sucked out by the fan to provide power.

[0043] In some embodiments, the hazardous chemical waste collection device also includes a first tube 4, the first end of the first tube 4 is located on the outside of the barrel body 1, and the second end of the first tube 4 extends into the barrel body 1. The first tube 4 is configured to blow air into the barrel body 1 to disturb the liquid hazardous chemicals in the barrel body 1.

[0044] In the above embodiment, by blowing air into the barrel body 1 through the first pipe 4, the liquid hazardous chemicals in the barrel body 1 can be disturbed, thereby accelerating the volatilization of the liquid hazardous chemical waste in the barrel body 1, which is conducive to generating high-concentration exhaust gas.

[0045] In some embodiments, the hazardous chemical waste collection device further includes a blower connected to the first pipe 4 for providing gas to the first pipe 4 .

[0046] In some embodiments, the hazardous chemical waste collection device further includes a second tube 5 , a first end of the second tube 5 is connected to the second end of the first tube 4 , and the second end of the second tube 5 extends into the bottom of the barrel 1 .

[0047] In the above embodiment, the second tube 5 extends into the bottom of the barrel body 1, which can disturb the hazardous chemicals from the bottom of the liquid hazardous chemicals, better accelerate the volatilization of the liquid hazardous chemical waste in the barrel body 1, and is conducive to the generation of high-concentration exhaust gas.

[0048] In some embodiments, the hazardous chemical waste collection device further includes a third pipe 6 and a fourth pipe 7. The fourth pipe 7 is constructed as an annular pipe and is provided with a plurality of second holes 71. The middle region of the third pipe 6 is connected to the second end of the second pipe 5, and the two ends of the third pipe 6 are connected to different parts of the fourth pipe 7, respectively.

[0049] In some embodiments, a plurality of second holes 71 are arranged in a circle along the fourth tube 7 .

[0050] In the above embodiment, the gas introduced by the first tube 4 passes through the second tube 5 and the third tube 6, and is finally discharged from the multiple second holes 71 set on the fourth tube 7. The fourth tube 7 is an annular tube, and the second holes 71 are set along the fourth tube 7. The gas can be discharged from multiple positions, and the liquid hazardous chemicals in the barrel body 1 are fully and evenly disturbed, thereby improving the volatilization of liquid hazardous chemical waste, which is conducive to the generation of high-concentration exhaust gas.

[0051] In some embodiments, the first tube 4 or other blast tube inserted into the barrel body 1 is suitable for collecting the volatilization of liquid hazardous chemicals. The specific operation process is: the liquid waste of hazardous chemicals generated in the production process is placed in the barrel body 1 for volatilization, and the waste gas generated by volatilization is sent to the waste gas treatment equipment through the connecting pipe 3.

[0052] In some embodiments, the exhaust area in the connecting pipe 3 is provided with a plurality of first holes 21, which can form a filter mesh exhaust area, thereby preventing debris from being sucked into the exhaust gas treatment equipment.

[0053] In some embodiments, the hazardous chemical waste collection device further includes a fan control system, and the fan control system is used to control the rotation speed of the fan.

[0054] The fan is adjusted through the fan control system to control the volatilization suction force in the barrel body 1. At the same time, an anti-corrosion blower pipe (first pipe 4, second pipe 5, third pipe 6, fourth pipe 7) is installed in the barrel body 1. The first pipe 4 is externally connected to a blower or air compressor that can be automatically turned on and adjusted for intelligent control.

[0055] When the exhaust gas concentration entering the exhaust gas treatment equipment is low and cannot maintain a self-sustaining state, the fan control system controls the fan to increase suction and turns on the blower or air compressor to stir the liquid hazardous chemicals, accelerating the volatilization of hazardous chemical wastes, so as to facilitate the volatilization to produce high-concentration exhaust gas. This can not only save the operating energy consumption of the exhaust gas treatment equipment, but also reduce the discharge of hazardous chemical liquid wastes. When there are too many hazardous chemical liquid wastes in the barrel body 1 and the liquid level of the liquid hazardous chemicals is higher than the warning line, stop adding hazardous chemical liquid wastes into the barrel body 1, and add volatilized hazardous chemical liquid wastes into the barrel body 1 after the liquid level is lower than the warning line.

[0056] refer to Figure 3 In some embodiments, the hazardous chemical waste collection device further includes a filter screen 8, which is disposed in the barrel body 1 and has a preset distance from the bottom of the barrel body 1, and the filter screen 8 is configured to carry solid hazardous chemicals.

[0057] In the above embodiment, by setting the filter screen 8 in the barrel body 1, the solid hazardous chemicals are placed on the filter screen 8, which is suitable for the volatilization collection of solid hazardous chemicals. The liquid hazardous chemicals mixed in the solid hazardous chemicals fall into the barrel body 1 through the filter screen 8 and are located below the filter screen 8.

[0058] In some embodiments, the hazardous chemical waste collection device further includes a support frame 9, which is disposed in the barrel body 1, and the filter screen 8 is placed on the support frame 9. The filter screen 8 is supported by the support frame 9 so that there is a preset distance between the filter screen 8 and the bottom of the barrel body 1, so as to separate liquid hazardous chemicals from solid hazardous chemicals.

[0059] The solid waste of hazardous chemicals generated during the production process, such as rags and gloves stained with volatile chemicals, are put into the barrel 1 and placed on the filter 8. The solid hazardous chemicals are volatilized on the filter 8 in the barrel 1.

[0060] In some embodiments, the exhaust area in the connecting pipe 3 is provided with a plurality of first holes 21, which can form a filter mesh exhaust area, thereby preventing debris from being sucked into the exhaust gas treatment equipment.

[0061] In some embodiments, the hazardous chemical waste collection device further includes a fan control system, and the fan control system is used to control the rotation speed of the fan.

[0062] The fan is adjusted through the fan control system to control the volatilization suction force in the barrel body 1. At the same time, an anti-corrosion blower pipe (first pipe 4, second pipe 5, third pipe 6, fourth pipe 7) is installed in the barrel body 1. The first pipe 4 is externally connected to a blower or air compressor that can be automatically turned on and adjusted for intelligent control.

[0063] In some embodiments, the fan automatically adjusts the volatilization suction of the barrel 1 through the fan control system, and performs intelligent control at the same time. When the exhaust gas concentration entering the exhaust gas treatment equipment is low and cannot maintain a self-sustaining state, the fan control system controls the fan to increase the suction force, accelerate the volatilization of hazardous chemical waste, and volatilize to produce high-concentration exhaust gas.

[0064] When the hazardous chemicals in the hazardous chemical solid waste are evaporated, the weight of the hazardous chemical solid waste becomes lighter. At the same time, the volatilized rags can be reused, and the generated hazardous waste is further reduced.

[0065] When the hazardous chemicals placed on the filter 8 are in a solid-liquid mixed state, the liquid hazardous chemicals flow through the filter 8 to the bottom of the filter 8. When the liquid level of the hazardous chemical waste in the barrel 1 is too high, the addition of the hazardous chemical solid waste is stopped. After the liquid hazardous chemical waste is volatilized and the liquid level is lower than the warning line, the hazardous chemical solid waste is added for filtering and volatilization, or the excess hazardous chemical liquid waste is moved to the barrel 1 with the blast pipe for volatilization disposal.

[0066] In some embodiments, the support frame 9 includes three legs 91 and a support surface 92 . The three legs 91 are supported and connected to the support surface 92 , and the support surface 92 is constructed as a hollow structure.

[0067] The support surface 92 is configured as a hollow structure, which is conducive to the liquid hazardous chemicals passing through the filter screen 8 and the support surface 92 to flow to the bottom of the filter screen 8, and can allow the solid hazardous chemicals to remain on the filter screen 8 for volatilization.

[0068] In some embodiments, the inner wall of the barrel body 1 is provided with a support platform protruding toward the center of the barrel body 1, and the support platform abuts against the outer circumferential area of ​​the filter screen 8 to support the filter screen 8 so that there is a preset distance between the filter screen 8 and the bottom of the barrel body 1.

[0069] In the above embodiment, three support platforms may be arranged at intervals in the circumferential direction of the inner wall of the barrel body 1 to support the filter screen 8 .

[0070] In the above embodiment, a hook may be further provided on the inner wall of the barrel body 1 , and the filter screen 8 is connected through the hook to prevent the filter screen 8 from falling to the bottom of the barrel body 1 .

[0071] In some embodiments, the hazardous chemical waste collection device further includes a liquid level sensor 10, which is disposed in the barrel 1 and is configured to detect the liquid level in the barrel 1. When the liquid level sensor 10 detects that the liquid level in the barrel 1 is higher than a preset value, an alarm is issued to stop adding hazardous chemicals into the barrel 1.

[0072] In some embodiments, the cover plate 2 includes a first cover body 22 and a second cover body 23 rotatably connected to each other. The first cover body 22 and the second cover body 23 can be opened separately, and the exhaust area is provided in the first cover body 22 .

[0073] In the above embodiment, the second cover 23 can be opened to inject liquid hazardous chemicals into the barrel 1, or solid hazardous chemicals can be placed on the filter 8. The first cover 22 can remain stationary without affecting the connection with the exhaust gas treatment equipment.

[0075] The utility model is suitable for the volatilization collection of solid hazardous chemicals and the volatilization collection of liquid hazardous chemicals. By centrally collecting and volatilizing solid hazardous chemical and liquid hazardous chemical wastes, the waste gas generated by the volatilization is discharged to the waste gas treatment equipment for pollution-free treatment. It can provide high-concentration waste gas for equipment suitable for treating high-concentration waste gas, so as to ensure that the waste gas treatment equipment is in a self-sustaining state, reduce the operating energy consumption of the waste gas treatment equipment, and reduce production costs.

[0076] Hazardous chemical solid waste and hazardous chemical liquid waste are respectively placed in a volatilization unit suitable for collecting hazardous chemical solid waste and a volatilization unit suitable for collecting liquid waste for volatilization disposal. The hazardous chemical solid waste can be reduced in weight after volatilization and drying, and a small amount of solid waste remains after volatilization of hazardous chemical liquid waste, with a weight reduction of more than 90%.
