Technical Field
[0001] This utility model belongs to the technical field of incineration devices, specifically relating to a saline waste liquid incineration device. Background Technology
[0002] For toxic and harmful high-salinity wastewater generated in industrial production, an effective method is incineration. This involves burning the wastewater in an incinerator through spontaneous combustion or the addition of auxiliary fuel to eliminate harmful substances. However, conventional saline wastewater incineration devices only incinerate the saline wastewater and cannot fully incinerate it, thus affecting the effectiveness of the treatment. Utility Model Content
[0003] To address the problems mentioned in the background art, this utility model provides a saline waste liquid incineration device, which solves the problem that the single method of incinerating saline waste liquid cannot fully incinerate it, thus affecting the performance.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a saline waste liquid incineration device, comprising a first incineration box, a connecting pipe connected to one side of the first incineration box, a second incineration box connected to one end of the connecting pipe, a high-pressure atomizer installed on the top of the first incineration box, a waste liquid conveying pipe connected to the input end of the high-pressure atomizer, an air conveying pipe connected to the surface of the waste liquid conveying pipe, a first discharge pipe installed at one end of the second incineration box, and burners installed on the other side of both the first and second incineration boxes, a diverter pipe connected to the input end of the burner, a three-way control valve connected to one end of the diverter pipe, and an air inlet pipe connected to one side of the three-way control valve.
[0005] Preferably, a second discharge pipe is provided at the bottom of the other side of the first incinerator, and the second discharge pipe extends into the interior of the first incinerator. A motor is provided at one end of the second discharge pipe, and the output end of the motor is connected to a rotating shaft. The surface of the rotating shaft is provided with a spiral blade, and both the rotating shaft and the spiral blade are located inside the first incinerator.
[0006] Preferably, the inner wall of the first incinerator is provided with inclined sliding plates, and one end of the inclined sliding plate is connected to the second discharge pipe.
[0007] Preferably, explosion-proof doors are installed on the upper side of one end of both the first incinerator and the second incinerator.
[0008] Preferably, a one-way solenoid valve is installed on the surface of both the air delivery pipe and the waste liquid delivery pipe.
[0009] Preferably, a discharge pipe is provided at the bottom of the surface of the second discharge pipe, and a threaded cap is threadedly connected to the bottom of the discharge pipe.
[0010] Preferably, the bottom of the first incinerator and the second incinerator are respectively provided with support legs around their perimeter, and the bottom of the support legs is provided with an anti-slip base.
[0011] Compared with the prior art, the beneficial effects of this utility model are: Air is delivered through an air supply pipe to the interior of the waste liquid supply pipe, mixing it with the saline waste liquid to increase the internal air volume and facilitate combustion. The mixed saline waste liquid then enters the interior of a high-pressure atomizer, where it is sprayed out in an atomized state inside the first incineration chamber. The burner then operates to incinerate the contents of the first incineration chamber at a temperature of 700 to 850 degrees Celsius. The atomized waste liquid remains in the first incineration chamber for a few seconds. The residual flue gas is transported through a connecting pipe to the interior of the second incineration chamber, where a burner located on one side operates to perform secondary incineration on the flue gas entering the explosion-proof door. The secondary incineration temperature is approximately 1100 degrees Celsius. This dual incineration process ensures thorough combustion of the saline waste liquid, preventing incomplete combustion in a single incineration and ensuring optimal performance.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0015] Please see Figure 1-3 The present invention provides the following technical solution: a saline waste liquid incineration device, including a first incineration box 1, a connecting pipe 7 connected to one side of the first incineration box 1, a second incineration box 8 connected to one end of the connecting pipe 7, a high-pressure atomizer 3 provided on the top of the first incineration box 1, a waste liquid conveying pipe 5 connected to the input end of the high-pressure atomizer 3, an air conveying pipe 4 connected to the surface of the waste liquid conveying pipe 5, a first discharge pipe 10 provided at one end of the second incineration box 8, and burners 9 provided on the other side of both the first incineration box 1 and the second incineration box 8, a diversion pipe 19 connected to the input end of the burner 9, a three-way control valve 17 connected to one end of the diversion pipe 19, and an air inlet pipe 18 connected to one side of the three-way control valve 17.
[0016] In this embodiment, the main bodies of the first incinerator 1 and the second incinerator 8 both adopt a vertical refractory structure. Due to the high temperature inside the incinerator, some salt in the waste liquid will vaporize and turn into salt particles as the flue gas cools during the incineration process. 80-90% of the salt residue falls into the primary incineration chamber, and the fallen salt residue falls to the bottom of the first incinerator 1. Then, the motor 15 works, so that the motor 15 drives the salt residue to move through the rotating shaft 21 and the spiral blade 20, so that the salt residue is transported outward and then discharged through the discharge pipe 14, thereby increasing the convenience of discharge and avoiding the accumulation of salt residue, which would affect the use effect.
[0017] In this embodiment: by setting an inclined slide plate 22, one end of which is connected to the second discharge pipe 16, the salt residue can slide down the inclined slide plate 22 into the interior of the second discharge pipe 16, so that it can be easily discharged through the rotating shaft 21 and the spiral blade 20, thereby increasing the processing effect and preventing the salt residue from accumulating inside.
[0018] In this embodiment, by setting the threaded cap 13 to be threadedly connected to the feed tube 14, the sealing of the connection is increased, and leakage is avoided, which would affect the performance.
[0019] In this embodiment, one-way solenoid valves 6 are installed on the surfaces of both the air delivery pipe 4 and the waste liquid delivery pipe 5 to restrict backflow and prevent it from affecting the performance.
[0020] In this embodiment, an explosion-proof door 2 is installed to protect the device and increase its safety.
[0021] In this embodiment, the first incinerator 1 and the second incinerator 8 are supported by the support legs 12 and the anti-slip base 11, thereby increasing the stability of the equipment and preventing shaking that would affect its performance.
[0022] The working principle and usage process of this utility model are as follows: After installation, during use, the pipeline for conveying saline waste liquid is connected to the waste liquid conveying pipe 5, the pipeline for conveying air is connected to the air conveying pipe 4, and the pipeline for conveying natural gas is connected to the air inlet pipe 18. Air is then conveyed through the air conveying pipe 4 to the interior of the waste liquid conveying pipe 5, mixing with the saline waste liquid to increase the internal air volume, thus facilitating combustion. The mixed saline waste liquid enters the interior of the high-pressure atomizer 3 and is sprayed out by the high-pressure atomizer 3, causing the waste liquid to be atomized and located inside the first incinerator 1. Then, the burner 9 operates to ignite the interior of the first incinerator 1. The incineration process takes place at a temperature of 750-800°C. The atomized waste liquid remains in the first incineration chamber 1 for 2 seconds. The residual flue gas is transported to the interior of the second incineration chamber 8 through the connecting pipe 7. The burner 9 located on one side of the second incineration chamber 8 operates, thereby performing secondary incineration on the flue gas entering the explosion-proof door 2. The combustion temperature of the secondary incineration is around 1100°C. Through this dual incineration process, the saline waste liquid can be fully incinerated, avoiding incomplete incineration in a single incineration, which would affect the performance. All electrical equipment in this device is powered by an external power source, and all motors in this device are connected and controlled by a PLC control system.
[0023] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
