Description

Technical Field

[0001] The utility model relates to the technical field of waste gas pretreatment, in particular to a high-concentration waste gas incineration pretreatment device for hazardous waste industry. Background Art

[0002] In the hazardous waste industry, waste gas treatment faces numerous challenges. Exhaust gas emissions and concentrations fluctuate significantly, and the complex composition, high viscosity and high molecular weight components, and corrosive properties make stable operation of waste gas treatment equipment challenging. Furthermore, safety accidents at environmental protection facilities continue to occur. Currently, commonly used waste gas pretreatment processes, such as uniform air flow systems, scrubbing, filtration, and cyclone sedimentation, have some effectiveness at fixing waste gas components and concentrations. However, the unique characteristics of the hazardous waste industry make these conventional processes unsatisfactory. While mature, efficient, and energy-efficient, regenerative thermal incinerators (RTOs) for industrial organic waste gas incinerators impose strict requirements on the concentration and impurities of incoming waste gas.

[0003] The composite liquid sealant is the key to the exhaust gas pretreatment device, and its sealing during injection is of vital importance. However, when the composite liquid sealant is injected into the interior of the pretreatment device, poor sealing may occur. For example, when replacing the injector or adding the composite liquid sealant inside the injector, the injection port will inevitably be opened. At this time, external impurities may be introduced to destroy the characteristics of the liquid sealant, which will not only affect the composite liquid sealant's ability to dissolve different substances in the exhaust gas, making it unable to cope with complex exhaust gas components, but also reduce the buffering and anti-backfire effects of the pretreatment device, increase safety risks and affect the exhaust gas treatment effect, thereby reducing the practicality of the pretreatment device.

[0004] In view of this, we propose a high-concentration waste gas incineration pretreatment device for hazardous waste industry. Summary of the Invention

[0005] The purpose of the utility model is to solve the above shortcomings and provide a high-concentration waste gas incineration pretreatment device for the hazardous waste industry, which can keep the composite liquid sealing agent injection port sealed when the composite liquid sealing agent is injected.

[0006] Through the pushing member and auxiliary member on the mounting seat, the injector body is driven to move toward the sealing member and enter the interior of the pretreatment device body during the pushing process, so that the sealing member is opened. At the same time, the injector control member is continuously pushed to realize the injection of the composite liquid sealant into the pretreatment device body.

[0007] Therefore, the utility model provides a pretreatment device for incineration of high-concentration waste gas in the hazardous waste industry, which includes a pretreatment device body, an exhaust gas injection pipe, a composite liquid sealant injection port and an injector body, wherein the injector body includes at least an injector body and an injector control component, and a sealing member is provided on the upper end of the inner wall of the pretreatment device body near the composite liquid sealant injection port, and the sealing member is used to seal with the composite liquid sealant injection port;

[0008] A mounting seat is provided on the outer wall of the pretreatment device body near the composite liquid sealant injection port, transparent covers are connected to both sides of the upper surface of the mounting seat by hinges, a storage groove for storing the injector body is provided on the upper surface of the mounting seat, a pusher is provided on the side of the storage groove away from the composite liquid sealant injection port, and auxiliary parts are provided on both sides of the pusher;

[0009] During the pushing process, the pushing member drives the auxiliary member to move its position, so that the injector body is pushed toward the sealing member into the interior of the pretreatment device body. At the same time, the sealing member is opened, and the continuous pushing of the pushing member drives the injector control member to push, so that the composite liquid sealant enters the interior of the pretreatment device body.

[0010] As a further improvement of the present technical solution, the seal comprises at least a mounting block and a cover plate. The side of the mounting block away from the inner wall of the pretreatment device body is threadedly connected to the cover plate through an automatic reset hinge, and an elastic sealing ring is provided on the side of the composite liquid sealant injection port close to the cover plate.

[0011] As a further improvement of the present technical solution, the pushing member at least includes a cylinder, a push plate is provided at the end of the piston rod inside the cylinder, and movable grooves are provided on both sides of the storage groove.

[0012] As a further improvement of the present technical solution, the auxiliary part includes at least a movable plate, a sliding groove is provided inside the movable plate, a slider for sliding connection with the sliding groove is provided on the side of the push plate close to the movable plate, an elastic part is provided on the end of the sliding groove close to the cylinder, and the end of the elastic part away from the cylinder is fixedly connected to one side of the slider.

[0013] As a further improvement of the present technical solution, the elastic force of the elastic member is greater than the elastic force of the spring in the automatic reset hinge.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] In the high-concentration waste gas incineration pretreatment device for the hazardous waste industry, the synergistic effect of the sealing member, the pushing member and the auxiliary member is used to improve the sealing performance during the injection of the composite liquid sealant, prevent the entry of external impurities, and ensure the waste gas treatment capacity of the liquid sealant. This not only improves work efficiency and precision, and reduces the tediousness and errors of manual operation, but also controls the injection sequence through the synergistic effect of the pushing member and the auxiliary member, thereby improving the reliability and stability of the device, reducing the risk of failure, extending the service life of the equipment, and reducing economic losses, thereby improving the practicality of the pretreatment device.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] The composite liquid sealant is the key to the exhaust gas pretreatment device, and its sealing during injection is of vital importance. However, when the composite liquid sealant is injected into the interior of the pretreatment device, poor sealing may occur. For example, when replacing the injector or adding the composite liquid sealant inside the injector, the injection port will inevitably be opened. At this time, external impurities may be introduced to destroy the characteristics of the liquid sealant, which will not only affect the composite liquid sealant's ability to dissolve different substances in the exhaust gas, making it unable to cope with complex exhaust gas components, but also reduce the buffering and anti-backfire effects of the pretreatment device, increase safety risks and affect the exhaust gas treatment effect, thereby reducing the practicality of the pretreatment device.

[0027] See also Figure 1-Figure 4 The embodiment of the utility model shown in the figure comprises a pre-treatment device body 10, an exhaust gas injection pipe 11, a composite liquid sealant injection port 12 and an injector body 30. The injector body 30 comprises at least an injector body 31 and an injector control member 32. A sealing member 13 is provided on the inner wall of the pre-treatment device body 10 near the upper end of the composite liquid sealant injection port 12. The sealing member 13 is used to seal with the composite liquid sealant injection port 12.

[0028] A mounting base 20 is provided on the outer wall of the pretreatment device body 10 near the composite liquid sealant injection port 12. Transparent covers 201 are hingedly connected to both sides of the upper surface of the mounting base 20. A storage groove 21 for storing the injector body 30 is provided on the upper surface of the mounting base 20. A pusher 22 is provided on the side of the storage groove 21 away from the composite liquid sealant injection port 12. Auxiliary members 23 are provided on both sides of the pusher 22.

[0029] During the pushing process, the pushing member 22 drives the auxiliary member 23 to move its position, so that the injector body 31 is pushed toward the sealing member 13 into the interior of the pretreatment device body 10. At the same time, the sealing member 13 is opened, and the continuous pushing of the pushing member 22 drives the injector control member 32 to push, so that the composite liquid sealant enters the interior of the pretreatment device body 10.

[0030] First, the specific structure of the seal 13 is disclosed. The seal 13 at least includes a mounting block 131 (through Figure 4 The position of the mounting block 131 is known) and the cover plate 132. The side of the mounting block 131 away from the inner wall of the pretreatment device body 10 is threadedly connected to the cover plate 132 through an automatic reset hinge. The side of the composite liquid sealant injection port 12 close to the cover plate 132 is provided with an elastic sealing ring 133 (through Figure 2 The seal 13 is shown in the figure when it is not opened.

[0031] When the pusher 22 is pushed, it drives the injector body 31 toward the cover 132, causing the spring in the automatic reset hinge to deform. At the same time, the cover 132 is opened, and the injection head of the injector body 31 enters the interior of the pretreatment device body 10, and the elastic sealing ring 133 is used to wrap the outside of the injector body 31 to prevent external impurities from entering the interior of the pretreatment device body 10 during the injection process, thereby ensuring the purity of the composite liquid sealant, thereby ensuring the composite liquid sealant's ability to dissolve different substances in the exhaust gas, enabling it to better cope with complex exhaust gas components, reduce safety risks, and improve exhaust gas treatment effects, thereby improving the reliability and stability of the pretreatment device.

[0032] Next, the specific structure of the pusher 22 is disclosed. The pusher 22 at least includes a cylinder 221 (the position of the cylinder 221 is determined by the Figure 2 and Figure 3 As can be seen, a push plate 222 is provided at the end of the piston rod inside the cylinder 221, and a movable groove 223 is provided on both sides of the storage groove 21 (the position of the movable groove 223 is determined by the Figure 2 and Figure 3 can be known).

[0033] The cylinder 221 is powered on to make it work. The piston rod inside the cylinder 221 pushes the push plate 222 to move toward the composite liquid sealant injection port 12. At the same time, the auxiliary part 23 slides inside the movable groove 223, so that the injection head of the injector body 31 enters the interior of the pretreatment device body 10 until the end of the auxiliary part 23 is close to the end of the movable groove 223 close to the composite liquid sealant injection port 12. At this time, the piston rod inside the cylinder 221 continues to push to inject the composite liquid sealant into the interior of the pretreatment device body 10, which not only realizes the automation and efficiency of the injection process, reduces the tediousness and errors of manual operation, and improves work efficiency and injection accuracy. Moreover, through the control of the cylinder 221, the injection speed and pressure can be adjusted according to actual needs to adapt to the exhaust gas treatment requirements under different working conditions. At the same time, the sliding fit of the auxiliary part 23 in the movable groove 223 ensures the smoothness and accuracy of the movement of the injector body 31, thereby improving the performance and stability of the pretreatment device.

[0034] The specific structure of the auxiliary member 23 is disclosed again. The auxiliary member 23 at least includes a movable plate 231, a sliding groove 232 is provided inside the movable plate 231, a sliding block 234 for slidingly connecting with the sliding groove 232 is provided on the side of the push plate 222 close to the movable plate 231, an elastic member 233 is provided on the end of the sliding groove 232 close to the cylinder 221, and the end of the elastic member 233 away from the cylinder 221 is fixedly connected to one side of the sliding block 234 (according to Figure 2 and Figure 3 can be known).

[0035] When the end of the movable plate 231 is close to the inside of the movable groove 223 and close to one end of the composite liquid sealant injection port 12, the piston rod inside the cylinder 221 continues to push, causing the slider 234 to slide inside the slide groove 232. At the same time, the elastic member 233 also deforms and stretches with the movement of the slider 234, and the composite liquid sealant is injected into the interior of the pretreatment device body 10, which not only improves the stability and accuracy of the injection process, but also the setting of the elastic member 233 can play a buffering role in the injection process, reducing the impact caused by the instantaneous thrust of the cylinder 221, making the injection action softer. At the same time, the elastic member 233 can make the injector body 31 enter the interior of the pretreatment device body 10 first, and then inject the composite liquid sealant, avoiding leakage or inaccurate injection problems caused by improper injection sequence. In addition, the buffering effect of the elastic member 233 and the control of the injection sequence improve the reliability and stability of the pretreatment device, reduce the risk of failure of the equipment during operation, and at the same time, help to extend the service life of the equipment.

[0036] The elastic force of the elastic part 233 is greater than the elastic force of the spring in the automatic reset hinge, which enables the injector body 31 to enter the interior of the pretreatment device body 10 first, and then inject the composite liquid sealant when continuing to push the push plate 222, thereby preventing the injector control part 32 from being directly pushed when the injector body 31 has not entered the interior of the pretreatment device body 10, thereby causing waste of the composite liquid sealant. It also improves the safety and controllability of the operation, and at the same time, reduces equipment damage and maintenance costs caused by incorrect operation, thereby reducing economic losses.

[0037] In summary, the working principle of this solution is as follows: first, open the transparent cover 201, place the injector body 30 into the storage tank 21, and cover the transparent cover 201, then connect the power supply of the cylinder 221 to make it work, and push the piston rod inside the cylinder 221 to drive the push plate 222 to move toward the composite liquid sealant injection port 12, so that the spring in the automatic reset hinge is deformed, driving the cover plate 132 to open, and the injection head of the injector body 31 enters the interior of the pretreatment device body 10, and the elastic sealing ring 133 is used to wrap the outside of the injector body 31. At the same time, the movable plate 231 slides inside the movable groove 223, so that the injection head of the injector body 31 enters the interior of the pretreatment device body 10 until the end of the movable plate 231 is opened. The upper portion is close to the end of the composite liquid sealant injection port 12 inside the movable groove 223, and the piston rod inside the cylinder 221 continues to push, so that the slider 234 slides inside the slide groove 232. At the same time, the elastic member 233 is also deformed and elongated with the movement of the slider 234, so that the composite liquid sealant is injected into the interior of the pretreatment device body 10. After the injection is completed, the piston rod inside the cylinder 221 is reset, so that the elastic member 233 is reset, and the slider 234 is driven to slide inside the slide groove 232 until the movable plate 231 moves to the end of the movable groove 223 away from the composite liquid sealant injection port 12. At the same time, the rebound force of the spring in the automatic reset hinge closes the cover plate 132, and the injection of the composite liquid sealant is completed.
