[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.
[0025] Example 1
[0026] like Figures 1-3 As shown, this embodiment proposes a heating reactor for hazardous waste treatment, including a reactor body 1, a purification component 2 fixed on the side of the reactor body 1, and a crushing component 3 fixed on the top of the reactor body 1.
[0027] The purification component 2 includes a bracket 21, in which a purification pipe 22 is installed. A support column 23 is fixed to the top of the bracket 21, and a liquid storage tank 24 is fixed to the top of the support column 23. A delivery pump 25 is fixed inside the liquid storage tank 24. A delivery pipe 26 is sealed to the side of the delivery pump 25. The other end of the delivery pipe 26 passes through the top of the purification pipe 22 and is fixed with a spray head 27. The liquid storage tank 24 stores an alkaline solution, which causes the acidic gas inside the harmful gas to undergo a neutralization reaction with the alkali, thereby purifying the harmful gas.
[0028] The purification pipe 22 has a drainage groove 28 inside. The bottom of the purification pipe 22 away from the drainage groove 28 is sealed and connected to a drainage pipe 29. A valve 210 is installed on the side of the drainage pipe 29. The drainage groove 28 can prevent the liquid after spraying and purifying the harmful gas from flowing into the reaction vessel body 1. The liquid can flow through the drainage groove 28 into the drainage pipe 29 and be discharged. The valve 210 is used to control the opening and closing of the drainage pipe 29.
[0029] Five sets of conveying pipes 26 are provided, and the five sets of conveying pipes 26 are evenly distributed inside the purification pipe 22. The five sets of conveying pipes 26 can fully spray the gas, thereby preventing some gas from not being sprayed.
[0030] A suction fan blade 211 is installed at the end of the purification pipe 22 away from the reactor body 1. A filter screen 212 is installed inside the purification pipe 22. The filter screen 212 is installed directly below the suction fan blade 211. The suction fan blade 211 is used to draw out the harmful gas generated in the reactor body 1. The harmful gas is further filtered when it passes through the filter screen 212.
[0031] A gas sensor 213 is fixed inside the reactor body 1. The gas sensor 213 is a TGS2611-E00 sensor. The gas sensor 213 is electrically connected to the delivery pump 25 via a PLC.
[0032] In this embodiment, after the waste materials are thoroughly stirred inside the reactor body 1, the harmful gas generated inside the reactor body 1 is drawn in by the suction fan blade 211 and flows into the purification pipe 22. When the harmful gas passes through the gas sensor 213, the gas sensor 213 detects the gas change, and then controls the delivery pump 25 to work through the PLC. The alkaline solution is delivered to the delivery pipe 26 through the delivery pump 25 and sprayed into the harmful gas inside the purification pipe 22 through the spray head 27. The alkaline solution neutralizes the acidic gas in the harmful gas, thereby purifying the harmful gas. The purified harmful gas is then filtered through the filter screen 212 and discharged from the top of the suction fan blade 211. The alkaline solution sprayed into the purification pipe 22 flows into the drain pipe 29 through the drain trough 28, and the alkaline solution can be cleaned by opening the valve 210.
[0033] Example 2
[0034] like Figures 4-5 As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes that the crushing component 3 includes a motor 31, a rotating rod 32 is fixed at the output end of the motor 31, a stirring rod 33 is fixed on the side of the rotating rod 32, an extension block 34 is fixed at the bottom of the rotating rod 32, a rotating shaft 35 is fixed on the side of the extension block 34, and a crushing blade 36 is hinged in the rotating shaft 35.
[0035] There are four sets of crushing blades 36, which are symmetrically distributed on the outside of the extension block 34. The four sets of crushing blades 36 can crush the solid waste at the bottom of the reactor body 1, so that the inside of the reactor body 1 can be stirred more evenly.
[0036] The external shape of the crushing blade 36 is streamlined. The streamlined shape of the crushing blade 36 makes it easier for the crushing blade 36 to expand outward when the rotating rod 32 drives the crushing blade 36 to rotate, thereby increasing the crushing area.
[0037] In this embodiment, when waste and other items are placed inside the reactor body 1, the motor 31 drives the rotating rod 32 to rotate, causing the stirring rod 33 to stir the waste and other items. During the stirring process, the solid waste accumulates at the bottom of the reactor body 1 by gravity. The crushing blade 36 is extended outward by the rotating shaft 35 through the rotation of the rotating rod 32, so that the crushing blade 36 is in an inclined state, thereby enabling the crushing blade 36 to crush the solid waste at the bottom of the reactor body 1.
[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
