[0002] Petrochemical waste residue refers to the solid waste generated in the process of petrochemical production. These wastes usually come from the pretreatment, refining, chemical reaction and separation processes of raw materials, and may include unreacted raw materials, catalysts, sludge and other solid impurities. These waste residues may contain certain harmful components, so they need to be properly treated. Incineration can significantly reduce the volume and weight of the waste residue, facilitating subsequent management and disposal. High-temperature incineration can effectively degrade or transform the harmful substances in the waste residue, reducing the environmental pollution risk.

[0003] In the prior art, the flue gas after petrochemical waste residue incineration will be treated and then discharged into the air. Since the flue gas after incineration is high-temperature flue gas and no recycling is carried out on it, the waste of heat energy resources is increased. Therefore, a petrochemical waste residue incineration and heat energy comprehensive utilization device is needed. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem that when the existing equipment is in use, due to the lack of recycling of the high-temperature flue gas generated after incineration, the waste of heat energy resources is increased, and a petrochemical waste residue incineration and heat energy comprehensive utilization device is proposed.

[0016] In the present utility model, through the action of the first temperature sensor and the controller, when the water temperature in the water tank reaches a certain temperature, the valve is opened, and the hot water inside the water tank will be utilized by other devices along the water outlet pipe. Then, through the action of the second temperature sensor, the temperature of the flue gas passing through the water tank can be detected.

Driving rods 8 are fixedly installed on one side of the outer walls of the two driving motors 7. A plurality of stirring blades 9 are fixedly installed on the outer walls of the two driving rods 8.

[0028] The effect achieved by the entire embodiment 1 is that when the petrochemical waste residue is completely incinerated in the main incinerator body 2, under the action of the blower 17, the high-temperature flue gas will enter the water tank 5 along the smoke pipe 4. At this time, the driving motors 7 installed on the two fixing plates 6 are started through the controller 19, so that the two driving rods 8 drive and rotate inside the two fixing blocks 10, thereby driving the plurality of stirring blades 9 to rotate in the water tank 5, so as to increase the fluidity of the water, improve the contact area between the water and the smoke pipe 4 and the high-temperature flue gas inside it, ensure that the water in the water tank 5 can more effectively absorb the heat in the high-temperature flue gas, and thus through the heat exchange between the flue gas and the water, it can recover the heat energy generated during the incineration process, reduce heat loss, improve energy efficiency, and thus improve the use effect of the device for incinerating petrochemical waste residue and comprehensively utilizing heat energy.

[0029] Embodiment 2, as Figures 2 - 6 shown, two fixing blocks 10 are fixedly installed on one side of the inner wall of the water tank 5, and the outer walls of the two driving rods 8 are movably inserted into the two fixing blocks 10. A first temperature sensor 11 is fixedly installed on one side of the inner wall of the water tank 5. A water inlet pipe 12 is fixedly installed on one side of the outer wall of the water tank 5. A water outlet pipe 13 is fixedly installed on one side of the outer wall of the water tank 5. A valve 14 is fixedly installed on the outer wall of the water outlet pipe 13. A top plate 15 is fixedly installed on the top of the water tank 5. A flue gas treatment device 16 is fixedly installed on the top of the support 3, and the output end of the smoke pipe 4 is communicated with the inside of the flue gas treatment device 16. A blower 17 is fixedly installed on the top of the support 3. A connecting pipe 18 is fixedly installed on one side of the outer wall of the blower 17, and the output end of the connecting pipe 18 is communicated with the inside of the flue gas treatment device 16. A controller 19 is fixedly installed on one side of the outer wall of the water tank 5, and one side of the outer wall of the controller 19 is electrically connected to the outer wall of the first temperature sensor 11. A second temperature sensor 20 is fixedly installed on the outer wall of the smoke pipe 4. A water collecting tank 21 is fixedly installed on the top of the operation panel 1. A first water adding pipe 22 is fixedly inserted into the top of the water collecting tank 21. A water pump 23 is fixedly installed on the outer wall of the first water adding pipe 22. A second water adding pipe 24 is fixedly inserted into one side of the outer wall of the water collecting tank 21.

[0030] The effect achieved by the entire Embodiment 2 is that since the first temperature sensor 11 is fixedly installed on one side of the inner wall of the water tank 5, and the first temperature sensor 11 is electrically connected to the controller 19, the temperature inside the water tank 5 is monitored by the first temperature sensor 11. When the water temperature reaches a certain value, the valve 14 is opened, and the hot water is applied to other fields along the water outlet pipe 13. Since the second temperature sensor 20 is installed on the outer wall of the water tank 5 where the smoke pipe 4 exits, the temperature of the smoke pipe 4 here is detected by the second temperature sensor 20. When the temperature exceeds a certain value, it indicates that the heat in the high-temperature flue gas passing through the water tank 5 has not been fully absorbed. At this time, the water pump 23 on the first water supply pipe 22 is turned on, and the cold water in the water collection tank 21 enters the water tank 5 along the first water supply pipe 22, increasing the heat energy exchange between the cold water and the high-temperature flue gas in the smoke pipe 4 until the value of the second temperature sensor 20 reaches the set value. Secondly, the flue gas whose heat has been absorbed enters the flue gas treatment device 16 along the smoke pipe 4. The flue gas treatment device 16 includes physical sedimentation, catalytic oxidation, wet desulfurization, activated carbon adsorption, etc. Through a series of multi-stage treatments, the emission standard is achieved, and the environment will not be polluted.

[0031] Working principle: First, after the petrochemical waste residue burns in the incinerator main body 2, under the action of the fan 17, the high-temperature flue gas generated will enter the water tank 5 along the smoke pipe 4. At this time, two driving motors 7 are started, which drive two driving rods 8 and a plurality of stirring blades 9 to rotate in the water tank 5, thereby increasing the fluidity of the water and increasing the contact area between the water and the smoke pipe 4 and the high-temperature flue gas in the smoke pipe 4, ensuring the heat exchange efficiency between the high-temperature flue gas and the water, so that the heat energy in the high-temperature flue gas generated by the combustion of the petrochemical waste residue is fully utilized. Then, under the action of the first temperature sensor 11, when the water temperature reaches a certain temperature, the valve 14 is opened, and the hot water is applied to other fields along the water outlet pipe 13. Then, the water tank 5 is filled with water through the water inlet pipe 12. Secondly, the temperature of the smoke pipe 4 here is detected by the second temperature sensor 20. When the temperature exceeds a certain value, it indicates that the heat in the high-temperature flue gas passing through the water tank 5 has not been fully absorbed. At this time, the water pump 23 on the first water supply pipe 22 is turned on, and the cold water in the water collection tank 21 enters the water tank 5 along the first water supply pipe 22, further increasing the heat energy exchange between the cold water and the high-temperature flue gas in the smoke pipe 4 until the value of the second temperature sensor 20 reaches the set value. Secondly, the flue gas enters the flue gas treatment device 16, and through the multi-stage treatment inside it, the flue gas reaches the emission standard and will not pollute the environment. Generally speaking, the use effect of the petrochemical waste residue incineration and heat energy comprehensive utilization device is improved.
