Abstract
Description
Technical Field
[0001] This utility model relates to the field of ammonia-containing waste gas treatment technology, specifically to a waste gas treatment device for synthetic ammonia production. Background Technology
[0002] Ammonia, a gas that is easily soluble in water, is produced in large quantities in waste gases from industries such as metal smelting and chemical production. In order to reduce the pollution of ammonia-containing waste gases to the environment, it is necessary to treat them.
[0003] A search revealed that patent document CN215822757U discloses an ammonia-containing waste gas treatment device. This device includes an air intake system, a conduit, and a reaction tank. The air intake system includes a waste gas inlet pipe, an inert gas inlet pipe, an air inlet pipe, and an air intake control cabinet. The reaction tank is connected to the air intake system via the conduit. The ammonia-containing waste gas treatment device also has a reaction tank inlet and an outlet, located at the top and bottom of the reaction tank, respectively. The device also has a perforation hole located at the bottom of the reaction tank. Furthermore, the device has a mixed gas outlet located at the bottom of the air intake system. The device also has a mixed gas inlet and a gas outlet, with the mixed gas inlet located at the bottom of the reaction tank and connected to the mixed gas outlet via the conduit. The gas outlet is located at the top of the reaction tank.
[0004] In operation, the aforementioned treatment device mixes ammonia-containing waste gas, inert gas, and oxygen to form a mixed gas, which is then introduced into a reaction tank through a conduit. Simultaneously, reactants and additives are added to the reaction tank through the inlet, causing the mixed gas to react within the tank. However, the conduit is in a fixed position during this process, meaning the mixed gas can only be directed to a constant location within the reaction tank. This can lead to uneven distribution of the mixed gas within the tank. Even with a stirrer, the area that the stirrer can agitate is limited, thus restricting its effectiveness in distributing the mixed gas within the tank.
[0005] Based on this, we propose a waste gas treatment device for ammonia synthesis to solve the above problems. Utility Model Content
[0006] The purpose of this invention is to address the problems in the prior art by proposing a waste gas treatment device for ammonia synthesis production. This device delivers ammonia-containing waste gas into the reaction chamber through a gas pipe, and simultaneously utilizes a driving component to move the gas pipe inside the reaction chamber, achieving uniform distribution of the ammonia-containing waste gas within the reaction chamber and improving treatment efficiency.
[0007] To solve the above problems, this utility model provides the following technical solution:
[0008] A waste gas treatment device for ammonia synthesis includes a reaction chamber and a gas pipe disposed inside the reaction chamber. The gas pipe is movable along the height direction of the reaction chamber. The gas pipe has a plurality of gas outlets along its length direction. The treatment device also includes a driving component for driving the gas pipe to reciprocate inside the reaction chamber so that the waste gas discharged from the gas outlets is evenly distributed inside the reaction chamber.
[0009] As a further embodiment of this utility model: a guide rod is fixedly provided on the side wall of the reaction chamber, and the guide rod is arranged along the height direction of the reaction chamber. A counterweight is slidably installed on the guide rod, and a driving component is used to drive the counterweight to reciprocate inside the reaction chamber. The gas pipe is set inside the reaction chamber by means of the counterweight.
[0010] As a further embodiment of this utility model: the driving component includes a winding drum disposed outside the reaction chamber, and a wire bundle is wound on the winding drum. One end of the wire bundle extends into the reaction chamber and is fixedly connected to the counterweight. The driving component also includes a drive motor, which is used to drive the winding drum to rotate, so as to realize the winding drum winding or unwinding of the wire bundle.
[0011] As a further embodiment of this utility model: the air pipe includes two parallel pipes, both of which are set on the counterweight, and a connecting pipe is provided between the two parallel pipes. The connecting pipe has the plurality of air outlets opened along its length direction.
[0012] As a further embodiment of this utility model, a nozzle is connected to the air outlet.
[0013] As a further embodiment of this invention, the processing equipment also includes a stirring assembly disposed inside the reaction chamber.
[0014] As a further embodiment of this utility model: the gas pipes are configured as two sets and respectively arranged on both sides of the reaction chamber, and the stirring assembly is located between the two sets of gas pipes.
[0015] As a further embodiment of this utility model: the stirring assembly includes a rotating shaft rotatably disposed inside the reaction chamber, a plurality of stirring rods fixedly disposed on the rotating shaft along its length direction, and a stirring motor that is drively connected to the rotating shaft is fixedly disposed on the reaction chamber.
[0016] As a further embodiment of this utility model: the top of the reaction chamber is connected to an inlet pipe and an exhaust pipe, and the bottom of the reaction chamber is connected to a drain pipe.
[0017] As a further embodiment of this utility model: the parallel pipe is connected to a delivery hose.
[0018] Compared with the prior art, the present invention has the following beneficial effects:
[0019] 1. The advantage of this waste gas treatment equipment lies in its unique design. Through the gas pipe that can move along the height of the reaction chamber and the driving component that drives its movement, the waste gas is evenly distributed inside the reaction chamber, which improves the efficiency and effect of waste gas treatment.
[0020] 2. By setting guide rods on the side wall of the reaction chamber and slidingly installing counterweights, this design not only provides stable guidance for the movement of the gas pipes, but also further enhances the uniformity and stability of the waste gas treatment through the reciprocating motion of the counterweights.
[0021] 3. The drive unit adopts an external winding drum and wire harness design, combined with a drive motor, to realize the automated control of the reciprocating motion of the counterweight and gas pipe inside the reaction chamber, thereby improving the reliability and ease of operation of the equipment.
[0022] 4. The gas duct is designed as two parallel pipes connected by a connecting pipe, which not only increases the exhaust area but also achieves uniform exhaust discharge through the exhaust port on the connecting pipe, further improving the efficiency of exhaust gas treatment.
[0023] 5. The gas pipes are set into two groups and arranged on both sides of the reaction chamber. The stirring component is located between the two groups of gas pipes. This layout not only ensures the uniform distribution of waste gas, but also achieves full mixing of waste gas and reaction liquid, thus improving the overall treatment effect.
[0024] 6. The parallel pipe connection not only ensures the stable delivery of waste gas, but also enhances the flexibility and adaptability of the gas pipe to move inside the reaction chamber through the flexibility of the hose. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0030] like Figures 1-2 As shown, a waste gas treatment device for synthetic ammonia production includes a reaction chamber 1 and a drive component installed on the reaction chamber 1. The top of the reaction chamber 1 is connected to an inlet pipe 11 and an exhaust pipe 12, and the bottom of the reaction chamber 1 is connected to a drain pipe 13. The inlet pipe 11 can be used to transport the reaction materials into the reaction chamber 1, and the drain pipe 13 can be used to discharge the liquid inside the reaction chamber 1. A guide rod 3 is fixedly installed on the inner wall of the reaction chamber 1. The guide rod 3 is arranged along the height direction of the reaction chamber 1. A counterweight 4 is slidably installed on the guide rod 3. A gas pipe 2 is installed on the counterweight 4. A driving component is used to drive the counterweight 4 to move on the guide rod 3. Several gas outlets on the gas pipe 2 face the middle of the reaction chamber 1. A conveying hose 14 is connected to the gas pipe 2. The ammonia-containing waste gas is then conveyed into the gas pipe 2 through the conveying hose 14 and discharged into the reaction chamber 1 through the gas outlets on the gas pipe 2 to react with the reactants. The waste gas after the reaction is discharged to a designated location through the exhaust pipe 12.
[0031] This application enables the gas pipe 2 to move within the reaction chamber 1, allowing it to distribute ammonia-containing waste gas throughout the interior of the reaction chamber 1. This achieves uniform contact with the reactants, resulting in a large contact area, good contact effect, and improved treatment efficiency for ammonia-containing waste gas.
[0032] Regarding the aforementioned driving component, the driving component includes a spool 5 disposed outside the reaction chamber 1, with a wire harness 6 wound on the spool 5. One end of the wire harness 6 extends into the reaction chamber 1 and is fixedly connected to the counterweight 4. The driving component also includes a drive motor (not shown in the figure), which drives the spool 5 to rotate, thereby enabling the spool 5 to wind or unwind the wire harness 6. The winding or unwinding of the wire harness 6 can cause the counterweight 4 to move up and down at the guide rod 3. Of course, this application is not limited to setting the driving component to the above structure; it can also be set to other conventional technical means in the prior art, such as conventional lifting components, as long as they can achieve the up and down traction movement of the counterweight 4.
[0033] like Figure 2 As shown, further, the gas pipe 2 can be configured to include two parallel pipes 201, each mounted on the counterweight 4, and a connecting pipe 202 connecting the two parallel pipes 201. The connecting pipe 202 has several gas outlets along its length, and nozzles 7 are connected to the gas outlets. Of course, to increase the spray range of the nozzles 7 on the ammonia-containing waste gas, the angle of the nozzles 7 on the connecting pipe 202 can be adjusted, and the required angle can be adjusted according to actual usage.
[0034] To further improve the mixing effect of ammonia-containing waste gas and reactants, this application may also install a stirring component inside the reaction chamber 1. The stirring component can fully mix the ammonia-containing waste gas and reactants entering the reaction chamber 1, so that the ammonia-containing waste gas sprayed from the nozzle 7 can be quickly carried away and will not accumulate in its spray area.
[0035] Based on the setup of the stirring assembly, the gas pipes 2 can be set into two sets and arranged on both sides of the reaction chamber 1 respectively. The stirring assembly is located between the two sets of gas pipes 2. When both sets of gas pipes 2 spray ammonia-containing waste gas towards the middle of the reaction chamber 1, the ammonia-containing waste gas on both sides will generate a convection effect. At the same time, under the stirring action of the stirring assembly, it can be more fully mixed and contacted with the reactants.
[0036] The stirring assembly mentioned above can be any stirring component in the prior art. For example, the stirring assembly can include a rotating shaft 8 rotatably disposed inside the reaction chamber 1, with multiple stirring rods 9 fixedly disposed on the rotating shaft 8 along its length direction, and a stirring motor 10 fixedly disposed on the reaction chamber 1 and drivenly connected to the rotating shaft 8.
[0037] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
