Description

Technical Field

[0001] The present application relates to the technical field of waste liquid incineration, and in particular to a small-volume integrated combined waste liquid spray gun. Background Art

[0002] At present, in the field of solid waste treatment, rotary kilns are often used as a highly efficient incineration equipment (incinerator) to treat various solid wastes. In order to improve the incineration efficiency and reduce operating costs, rotary kilns often use waste liquids with a certain high calorific value as supplementary combustion materials during the incineration process. These waste liquids can not only provide additional heat, but also react with harmful substances in solid waste through their chemical composition to achieve more thorough harmless treatment. In related technologies, waste liquid spray guns are usually used to atomize the waste gas and then spray it into the rotary kiln, and the waste liquid spray guns mostly adopt a split design, that is, the spray gun is installed separately on the kiln head hood of the rotary kiln, and is separately equipped with auxiliary equipment such as combustion-supporting air, fire detection and ignition.

[0003] Regarding the above-mentioned related technologies: In actual applications, the space at the kiln head of some rotary kilns is limited, and the space required for the split waste liquid spray gun is relatively large, which easily makes the waste liquid spray gun unsuitable for situations where space is limited. Summary of the invention

[0004] In order to make the waste liquid spray gun better adapt to the situation of limited space, the present application provides a small-volume integrated combination waste liquid spray gun.

[0005] The present application provides a small-volume integrated combined waste liquid spray gun, which adopts the following technical solution:

[0006] A small-volume integrated waste liquid spray gun comprises a shell, a spray gun body, an auxiliary module and a power module, wherein the power module, the spray gun body and the auxiliary module are sequentially arranged in the shell along the length direction of the shell, the auxiliary module is electrically connected to the power module, and the auxiliary module is used to ignite the mixture sprayed from the spray gun body and monitor the flame state;

[0007] A combustion-supporting chamber is formed between the shell and the spray gun body. The combustion-supporting chamber passes through the end surface of the shell away from the power module. A compressed air connector is provided on the shell, and the compressed air connector is connected to the combustion-supporting chamber.

[0008] By adopting the above technical solution, the power module, the spray gun body and the auxiliary module are integrated into the same shell, realizing the integrated design of the equipment. This integrated design not only reduces the installation space, but also improves the integration and stability of the system, so that the waste liquid spray gun can better adapt to the space limitations of the rotary kiln head. In addition, due to the close fit of the various components, the flame ignition and monitoring are more reliable, avoiding the problem of misjudgment of fire detection caused by external factors. And the design of the combustion chamber enables compressed air to be delivered to the shell through the compressed air connector to ensure sufficient supply of combustion air. This not only enhances the rigidity and stability of the flame, but also extends the flame length, making it more suitable for use in the rotary kiln. At the same time, the introduction of compressed air helps to improve the atomization effect of the waste liquid, thereby improving the combustion efficiency and reducing the discharge of incompletely burned waste liquid.

[0009] Optionally, the spray gun body includes a liquid inlet joint, an air inlet joint, an inner liquid inlet tube, an outer air inlet tube and an atomizer, the inner liquid inlet tube and the outer air inlet tube are respectively arranged in the shell and arranged along the length direction of the shell, the outer air inlet tube is sleeved on the inner liquid inlet tube, the liquid inlet joint and the air inlet joint are respectively arranged on the shell, the liquid inlet joint is communicated with the inner liquid inlet tube, and the air inlet joint is communicated with the outer air inlet tube;

[0010] The atomizer is arranged at one end of the liquid inlet inner tube away from the power module. The atomizer is respectively provided with a liquid inlet hole and an air inlet hole. The liquid inlet hole is communicated with the liquid inlet inner tube, and the air inlet hole is communicated with the air inlet outer tube.

The air inlet outer tube is sleeved on the liquid inlet inner tube, and the liquid inlet hole and the air inlet hole on the atomizer are respectively connected to the liquid inlet inner tube and the air inlet outer tube, so that the waste liquid and compressed air can be fully mixed at the atomizer, which is beneficial to improve the atomization effect of the waste liquid, and then to improve the combustion efficiency and stability. This structural design makes the flame sprayed by the spray gun rigid, slender and stable, which is suitable for use in incinerators, especially in the kiln head area with limited space, and effectively avoids interference with other solid waste combustion flames.

[0012] Optionally, a support sleeve is sleeved on one end of the air intake outer tube away from the power module, a support member is provided between the support sleeve and the atomizer, and the auxiliary module is provided between the support sleeve and the shell.

[0013] By adopting the above technical solution, the setting of the support sleeve makes the connection between the air inlet outer tube, the liquid inlet inner tube and the atomizer more stable, avoiding loosening caused by vibration or other external factors, thereby ensuring the stability of the waste liquid spray gun during operation. The support further enhances the fixing effect between the support sleeve and the atomizer, ensuring the normal operation of the atomizer under high pressure. In addition, the auxiliary module is set between the support sleeve and the shell, which not only saves space, but also facilitates installation and maintenance, and improves the reliability and service life of the overall equipment.

[0014] Optionally, pressure detectors are provided on the shell in sequence at positions corresponding to the liquid inlet connector, the air inlet connector and the compressed air connector.

[0015] By adopting the above technical solution, pressure detectors are sequentially arranged at the positions corresponding to the liquid inlet connector, air inlet connector and compressed air connector on the shell, which can monitor the pressure changes of each fluid in real time. This not only helps to ensure the stability of the pressure of each part of the waste liquid spray gun during operation, thereby improving the combustion efficiency and stability, but also can promptly detect and eliminate problems caused by abnormal pressure to ensure the safe operation of the equipment. Especially when applied to incinerators, this real-time monitoring function is particularly important for maintaining the rigidity and slenderness of the flame, effectively avoiding the interference of the flame of other solid waste burning in the kiln, and improving the incineration effect.

[0016] Optionally, the liquid inlet connector has the same structure as the air inlet connector, and comprises an external connecting tube and an internal hose, wherein the external connecting tube is movably disposed on the shell, and the internal hose is disposed inside the external connecting tube and is connected to the liquid inlet internal tube, and the external connecting tube is used to drive the internal hose to rotate to a position in contact with the shell surface.

[0017] By adopting the above technical solution, the external tube is movably arranged on the shell, which can drive the inner hose to rotate to a position in contact with the shell surface. On the one hand, the liquid inlet connector and the air inlet connector have high flexibility and stability during installation and use, and the position of the liquid inlet connector and the air inlet connector can be adjusted according to actual work needs, so as to facilitate the transportation of waste liquid and compressed air through the liquid inlet connector and the air inlet connector when space is limited. On the other hand, it is convenient for operators to perform maintenance, thereby improving the overall performance and reliability of the waste liquid spray gun.

[0018] Optionally, a plug-in slot is provided on the shell, and a through hole is provided on the shell along its length direction, one end of the through hole passes through the end face of the shell close to the power module, and the other end of the through hole is connected to the plug-in slot, the spray gun body includes a movable plate, the movable plate is movably arranged on the shell, the external tube is embedded in the movable plate, and when the movable plate is inserted into the plug-in slot, the external tube is connected to the through hole.

[0019] By adopting the above technical solution, the movable plate can drive the external tube to be inserted into the plug-in slot, so that the external tube is connected to the through hole, thereby facilitating the use of the through hole to transport waste liquid or compressed air into the external tube, so that the spray gun can spray flames, and when the installation space is limited, making it inappropriate to transport waste liquid or compressed air into the external tube through the through hole, the movable plate can drive the external tube to disengage from the plug-in slot to adjust the position of the external tube, which is beneficial to improve the flexibility of the spray gun during use, thereby improving the scope of application of the spray gun and ensuring the stability and reliability of the spray gun in the working state.

[0020] Optionally, a sliding groove is opened on the inner wall of the plug-in slot, a sealing component is slidably arranged in the sliding groove, a movable component is slidably arranged in the through hole, and the sealing component is used to seal the movable component in the through hole. When the movable plate is inserted into the plug-in slot, the sealing component shrinks into the sliding groove, and the movable component is inserted into the external tube and connected with the external tube.

[0021] By adopting the above technical solution, when the movable plate is not inserted into the plug-in slot, the blocking component can block the through hole to block the movable component in the through hole, and when the movable plate is inserted into the plug-in slot, the movable plate can push the blocking component to move into the slide slot to shrink the blocking component into the slide slot, and at the same time, the movable component can be smoothly inserted into the external pipe and connected thereto, thereby achieving a fast and reliable connection and improving operational convenience and maintenance efficiency.

[0022] Optionally, a sliding hole is opened in the shell, the sliding hole is connected to the through hole and is coaxial, the movable component includes a movable tube and a first elastic member, the movable tube is slidably set in the through hole, the movable tube extends out of the through hole at one end away from the movable plate, the first elastic member is set in the sliding hole and connected to the movable tube, when the movable plate is inserted into the plug-in slot, the first elastic member drives the movable tube to be inserted into the external tube and connected with the external tube.

[0023] By adopting the above technical solution, when the movable plate is inserted into the plug-in slot, the first elastic member can automatically drive the movable tube to be inserted into the external tube and connected thereto, thereby ensuring the connection reliability and sealing between the external device and the spray gun. This design not only simplifies the operation steps and improves work efficiency, but also effectively prevents leakage problems caused by poor connection and ensures the safe operation of the waste liquid spray gun. In addition, since the sliding hole and the through hole are coaxially arranged, the stability of the movable tube during movement is further improved, making the entire device more stable and reliable during use.

[0024] Optionally, the blocking assembly includes a blocking plate and a second elastic member, the blocking plate is slidably disposed in the slide groove, the second elastic member is disposed between the blocking plate and the inner wall of the slide groove, and the second elastic member is used to push the blocking plate to move out of the slide groove so that the blocking plate blocks the movable assembly in the through hole.

[0025] By adopting the above technical solution, when the movable plate is not inserted into the plug-in slot, the second elastic member pushes the blocking plate to move outward, so that the blocking plate fits tightly at the outlet of the through hole, thereby firmly blocking the movable component in the through hole. This not only avoids the invasion of external pollutants, but also ensures the safety and stability of the internal structure of the spray gun. When the movable plate is inserted into the plug-in slot, the blocking plate is compressed into the slide slot, and the movable component can be smoothly inserted into the external pipe and connected with it, realizing the normal operation of the spray gun. This design not only simplifies the operation steps, but also improves the reliability and service life of the equipment.

[0026] Optionally, the auxiliary module includes a support plate, an ion fire detector and an igniter. The support plate is arranged on the inner wall of the combustion-supporting chamber and close to the side of the spray gun body away from the power supply module. The ion fire detector and the igniter are respectively arranged on the support plate and electrically connected to the power supply module. The ion fire detector and the igniter are respectively arranged close to the end surface of the shell away from the power supply module.

[0027] By adopting the above technical solution, the support plate, ion flame detector and igniter are integrated on the inner wall of the combustion chamber and close to the side of the spray gun body away from the power module. This design allows the ion flame detector and igniter to be closer to the flame generation area, thereby ensuring timely and accurate detection of the flame state and rapid completion of the ignition process. Since the ion flame detector and igniter are directly electrically connected to the power module, signal transmission is more reliable, reducing the problem of signal attenuation caused by long lines. In addition, this compact design not only saves space, but also improves the overall stability of the system, avoids external interference, and ensures the normal operation of the waste liquid spray gun under complex working conditions.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:

[0029] 1. By integrating the power module, the spray gun body and the auxiliary module into the same housing, the integrated design of the equipment is realized, the integration and stability of the system are improved, thereby effectively reducing the volume of the waste liquid spray gun, so that the waste liquid spray gun can better adapt to the situation of limited space;

[0044] Reference Figure 3 and Figure 4 The spray gun body 2 mainly includes a liquid inlet joint 21, an air inlet joint 22, a liquid inlet inner tube 23, an air inlet outer tube 24 and an atomizer 25. The liquid inlet inner tube 23 and the air inlet outer tube 24 are respectively installed in the shell 1 and arranged along the length direction of the shell 1. The air inlet outer tube 24 is sleeved on the liquid inlet inner tube 23. This double-layer pipeline design is conducive to improving the uniform mixing effect of gas and liquid.

In this embodiment, the liquid inlet connector 21 is used to communicate with an external waste liquid conveying device so as to convey waste liquid to the liquid inlet inner tube 23 through the liquid inlet connector 21, and the air inlet connector 22 is used to communicate with an external air supply device so as to convey compressed air to the air inlet outer tube 24 through the air inlet connector 22.

[0046] Reference Figure 3 and Figure 4A support sleeve 26 is sleeved on one end of the air intake outer tube 24 away from the transformer 42 , and the circumferential inner wall of the support sleeve 26 away from the one end of the air intake outer tube 24 is spaced apart from the circumferential outer wall of the liquid inlet inner tube 23 .

[0047] The atomizer 25 is arranged at one end of the liquid inlet inner tube 23 away from the transformer 42, and a support member 27 is fixedly connected to the circumferential outer wall of the atomizer 25, and the support member 27 abuts against the circumferential inner wall of the support sleeve 26, thereby facilitating the fixing effect between the support sleeve 26 and the atomizer 25 to ensure the normal operation of the atomizer 25 under high pressure environment.

[0048] The atomizer 25 is provided with a liquid inlet hole 251 and an air inlet hole 252, respectively. The liquid inlet hole 251 is connected to the liquid inlet inner tube 23, and the air inlet hole 252 is connected to the air inlet outer tube 24 through the support sleeve 26. The atomizer 25 adopts a vortex design, and the liquid is broken into tiny particles by the high-speed rotating gas, thereby achieving an efficient atomization effect. In other embodiments, the support sleeve 26 may not be provided, and the air inlet hole 252 is directly connected to the air inlet outer tube 24.

[0049] Reference Figure 2 and Figure 3 , the auxiliary module 3 includes a support plate 31, an ion flame detector 32 and an igniter 33. The support plate 31 is fixed between the support sleeve 26 and the housing 1, and the ion flame detector 32 and the igniter 33 are respectively mounted on the support plate 31 and electrically connected to the transformer 42, and the ion flame detector 32 is used to detect whether the flame is burning normally, and the igniter 33 is responsible for igniting the mixture at startup. This integrated design not only saves space, but also improves the response speed and reliability of the system.

[0050] Reference Figure 2 and Figure 3 A combustion-supporting chamber 11 is formed between the circumferential inner wall of the housing 1 and the circumferential outer wall of the air inlet outer pipe 24, and the combustion-supporting chamber 11 is arranged through the end surface of the housing 1 away from the power module 4, and the auxiliary module 3 is located in the combustion-supporting chamber 11. A compressed air connector 12 is fixedly connected to the housing 1, and the compressed air connector 12 is connected to the combustion-supporting chamber 11. In this embodiment, the compressed air connector 12 is used to communicate with an external air supply device to facilitate the delivery of compressed air to the combustion-supporting chamber 11.

[0051] Reference Figure 3 The housing 1 is provided with pressure detectors 13 at positions corresponding to the liquid inlet connector 21, the air inlet connector 22 and the compressed air connector 12. In this embodiment, the pressure detector 13 is provided with a pressure gauge or a pressure sensor, so that the pressure detector 13 is used to monitor the pressure of various media entering the spray gun in real time, and then to facilitate accurate adjustment, thereby ensuring the stability and safety of the system operation.

[0052] The implementation principle of a small-volume integrated combined waste liquid spray gun in the embodiment of the present application is as follows: when the waste liquid spray gun needs to be started, compressed air is first delivered to the air inlet connector 22, and waste liquid is delivered to the liquid inlet connector 21, so that the compressed air enters the atomizer 25 through the air inlet outer tube 24 and the air inlet hole 252, and the waste liquid enters the atomizer 25 through the liquid inlet inner tube 23 and the liquid inlet hole 251, so that the waste liquid is atomized, and the mixture of waste liquid and air is sprayed out of the combustion-supporting chamber 11. At the same time, the igniter 33 works to ignite the mixture so that the waste liquid spray gun sprays fire. In this process, compressed air is delivered to the combustion-supporting chamber 11 through the compressed air connector 12 to form a combustion-supporting wind, further increasing the length of the flame, and thus facilitating the use of the waste liquid spray gun to incinerate solid waste in the rotary kiln.

[0053] The small-volume integrated waste liquid spray gun of this embodiment integrates multiple functional modules to achieve the effects of small size, strong flame rigidity, slender flame and online continuous adjustment, which is particularly suitable for working conditions with limited space at the head of the rotary kiln. Compared with the split design, this solution significantly reduces the floor space, simplifies the installation and maintenance process, and also improves the combustion efficiency and safety performance.

[0054] Example 2: Reference Figure 5 The difference between this embodiment and embodiment 1 is that the spray gun body 2 includes a movable plate 28, and the movable plate 28 is hinged on the shell 1.

[0055] A plug-in slot 14 is provided on the shell 1, and a through hole 15 is provided on the shell 1 along its length direction. One end of the through hole 15 passes through the end face of the shell 1 close to the power module 4, and the other end of the through hole 15 is connected to the plug-in slot 14. There are two through holes 15, and the two through holes 15 are respectively arranged in one-to-one correspondence with the air inlet connector 22 and the air inlet connector 22.

[0056] The liquid inlet connector 21 and the air inlet connector 22 are respectively connected to the movable plate 28. When the movable plate 28 rotates into the insertion slot 14, the movable plate 28 can drive the liquid inlet connector 21 and the air inlet connector 22 to move so that the liquid inlet connector 21 and the air inlet connector 22 are respectively connected to the two through holes 15.

[0057] The liquid inlet connector 21 has the same structure as the air inlet connector 22, and the liquid inlet connector 21 includes an external tube 211 and an internal hose 212. The external tube 211 is embedded in the movable plate 28, and the internal hose 212 is coaxially and fixedly connected to the external tube 211, and one end of the internal hose 212 extends into the housing 1 and communicates with the liquid inlet internal tube 23, so that when the movable plate 28 drives the external tube 211 to rotate, the internal hose 212 can rotate with the rotation of the external tube 211, so as to adjust the entry position of the medium. In other embodiments, the movable plate 28 may not be provided, and the external tube 211 may be directly hinged to the housing 1.

[0058] Reference Figure 5 A sliding groove 16 is provided on the inner wall of the plug-in groove 14, a blocking component 17 is slidably provided in the sliding groove 16, and a movable component 18 is slidably provided in the through hole 15. The blocking component 17 is used to block the movable component 18 in the through hole 15. When the movable plate 28 is inserted into the plug-in groove 14, the blocking component 17 is retracted into the sliding groove 16, and the movable component 18 is inserted into the external pipe 211 and communicated with the external pipe 211.

[0059] A sliding hole 19 is provided in the housing 1, and the sliding hole 19 is connected to and coaxial with the through hole 15. The movable assembly 18 includes a movable tube 181 and a first elastic member 182. The movable tube 181 is slidably disposed in the through hole 15, and one end of the movable tube 181 away from the movable plate 28 extends out of the through hole 15. The first elastic member 182 is disposed in the sliding hole 19 and is fixedly connected to the movable tube 181. In this embodiment, the first elastic member 182 is a spring, so that the first elastic member 182 is used to drive the movable tube 181 to be inserted into the plug-in slot 14.

[0060] The blocking assembly 17 includes a blocking plate 171 and a second elastic member 172. The blocking plate 171 is slidably disposed in the slide slot 16, and the second elastic member 172 is disposed between the blocking plate 171 and the inner wall of the slide slot 16. In this embodiment, the second elastic member 172 is a spring, so that the second elastic member 172 is used to drive the blocking plate 171 to be inserted into the insertion slot 14.

[0061] When the movable plate 28 is not inserted into the insertion slot 14 , the blocking plate 171 can block the through hole 15 under the action of the second elastic member 172 , so that the first elastic member 182 is not easy to push the movable tube 181 out of the through hole 15 , thereby avoiding the invasion of external pollutants.

[0062] The implementation principle of Example 2 is as follows: when it is necessary to transport the medium from the end of the housing 1, the movable plate 28 is rotated so that the movable plate 28 drives the external pipe 211 to be inserted into the plug-in slot 14. In this process, the movable plate 28 first contacts the blocking plate 171 and pushes the blocking plate 171 to move into the slide slot 16, so that the blocking plate 171 no longer blocks the through hole 15. At this time, the first elastic member 182 works to push the movable pipe 181 to move, so that the movable pipe 181 is inserted into the external pipe 211, thereby realizing the connection between the movable pipe 181 and the inner hose 212, and then facilitating the transportation of waste liquid and compressed air into the liquid inlet inner pipe 23 and the air inlet outer pipe 24 through the movable pipe 181 and the inner hose 212. At this time, the movable pipe 181 can limit the movable plate 28 to prevent the movable plate 28 from automatically rotating out of the plug-in slot 14.

[0063] When it is not necessary to transport the medium from the end of the housing 1, the movable tube 181 is first moved away from the movable plate 28, so that the movable tube 181 is separated from the external tube 211. At this time, the second elastic member 172 can drive the blocking plate 171 to move into the plug slot 14, and the blocking plate 171 pushes the movable plate 28 out of the plug slot 14, and the blocking plate 171 blocks the through hole 15, so as to facilitate the movable tube 181 to be restricted in the through hole 15. At this time, the movable plate 28 can drive the external tube 211 to move to a position perpendicular to the length direction of the housing 1, thereby completing the adjustment of the external tube 211.

[0064] In the embodiment of the present application, through the mutual cooperation of the movable plate 28, the movable tube 181 and the sealing plate 171, the positions of the air inlet connector 22 and the liquid inlet connector 21 can be adjusted according to actual work needs, thereby facilitating the transportation of waste liquid and compressed air through the liquid inlet connector 21 and the air inlet connector 22 when space is limited, so as to improve the flexibility of the waste liquid spray gun during use, which is beneficial to improve the scope of application of the waste liquid spray gun.

[0065] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
