Description

Technical Field

[0001] This utility model relates to the technical field of waste gas treatment equipment, and specifically to a spray tank for waste gas treatment equipment. Background Technology

[0002] In the field of waste gas treatment, spray absorption is a commonly used technology for removing particulate matter and harmful gases from waste gas. In the spray absorption process for waste gas treatment, the core pain points of the spray tank are concentrated in two aspects: insufficient gas-liquid mass transfer efficiency and inefficient sludge cleaning and maintenance. After entering the tank through the inlet pipe, the exhaust gas tends to flow in a directional manner, and when mixed with the spray liquid, a local "short circuit" phenomenon occurs, which limits the adsorption and removal efficiency of pollutants. Particulate matter or reaction byproducts in the exhaust gas tend to settle at the bottom of the tank. Traditional tanks require manual cleaning of the sediment after interrupting operation, which is not only time-consuming and labor-intensive, but also prone to tank blockage due to delayed cleaning, thus restricting the continuous operation capability of the equipment. Therefore, a spray tank for exhaust gas treatment equipment is proposed to improve the efficiency of exhaust gas treatment. Utility Model Content

[0003] This utility model aims to solve the above-mentioned technical problems by providing a spray tank for a waste gas treatment device.

[0004] The technical solution adopted by this utility model to solve the technical problem is as follows: a spray tank for a waste gas treatment device, including a tank body, one end of which is connected to an air inlet pipe, and a V-shaped baffle plate is fixedly connected inside the tank body near that end, with the groove of the V-shaped baffle plate facing the air inlet pipe; a partition plate is fixedly connected to the middle of the inner wall of the tank body, the top of the partition plate is fixedly connected to the top inner wall of the tank body, and the bottom of the partition plate is lower than the middle cross-section of the tank body; a slag discharge port is connected to the bottom of the end of the tank body away from the air inlet pipe, and a discharge pipe is fixedly connected to the bottom of the slag discharge port; a water inlet pipe is fixedly connected to the top of the tank body near the air inlet pipe, and a spray head is fixedly connected to the end of the water inlet pipe inside the tank body; and an air outlet pipe is connected to the top of the tank body away from the air inlet pipe.

[0005] As a preferred embodiment of this utility model, the discharge pipe is internally equipped with a spiral feeding rod driven by a servo motor, and a discharge port is provided at the bottom of the end of the discharge pipe away from the slag discharge port.

[0006] As a preferred embodiment of this utility model, a support leg is fixedly connected to the bottom of the outer wall of the tank, a universal wheel is fixedly provided at the bottom of the support leg, and a threaded lifting leg for adjusting the height is threadedly connected to the bottom of the support leg on one side of the universal wheel.

[0007] As a preferred embodiment of this utility model, the bottom of the tank is fixedly connected to a liquid outlet pipe, which is connected to the outside.

[0008] This invention has the following advantages: the V-shaped baffle inside the tank forcibly disperses the incoming airflow through grooves, breaking the directional flow trend; combined with the spatial layout of the bottom of the baffle being lower than the middle of the tank, the residence time and flow path of the exhaust gas are extended, so that the spray liquid and the exhaust gas form multi-level turbulent contact, significantly improving the pollutant purification efficiency; the discharge pipe at the bottom of the tank has a built-in servo motor-driven spiral feeding rod, which can continuously transport the sediment to the discharge port by spiral pushing, and the sediment can be discharged without stopping the machine, greatly reducing the cost of manual operation and maintenance, and ensuring the continuous and stable operation of the equipment.

They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0012] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0013] The present invention will be further described below with reference to the accompanying drawings.

[0014] Please refer to the following: Figure 1-3 This utility model discloses a spray tank for a waste gas treatment device, comprising a tank body 1. One end of the tank body 1 is connected to an air inlet pipe 3. A V-shaped baffle 4 is fixedly connected inside the tank body 1 near the air inlet pipe 3, with the groove of the V-shaped baffle 4 facing the air inlet pipe 3. A partition 7 is fixedly connected to the middle of the inner wall of the tank body 1, and the partition 7 is fixedly connected to the top of the tank body 1, with the bottom of the partition 7 lower than the middle of the tank body 1. A slag discharge port 9 is connected to the bottom of the tank body 1 away from the air inlet pipe 3, and a discharge pipe 10 is fixedly connected to the bottom of the slag discharge port 9. A water inlet pipe is fixedly connected to the top of the tank body 1 near the air inlet pipe 3. 5. A spray head 6 is fixedly connected to one end of the water inlet pipe 5 inside the tank body 1. An air outlet pipe 2 is connected to the top of the tank body 1 away from the air inlet pipe 3. A spiral feeding rod 11 driven by a servo motor is rotatably connected inside the discharge pipe 10. A discharge port 12 is opened at the bottom of the discharge pipe 10 away from the slag discharge port 9. A support leg 13 is fixedly connected to the bottom of the outer wall of the tank body 1. A universal wheel 14 is fixedly connected to the bottom of the support leg 13. A threaded lifting leg 15 is threadedly connected to the bottom of the support leg 13 on one side of the universal wheel 14. A liquid outlet pipe 8 communicating with the outside is fixedly connected to the bottom of the tank body 1.

[0015] Specifically, when this utility model is used, the exhaust gas enters the tank horizontally through the inlet pipe 3, and after hitting the groove of the V-shaped baffle 4, it is forcibly dispersed into multiple turbulent flows. When flowing, it is blocked by the baffle 7. The bottom of the baffle 7 is lower than the middle, so the airflow needs to bypass the bottom of the baffle, which prolongs the flow path and increases the residence time. At the same time, the top spray head 6 sprays and comes into contact with the exhaust gas in the opposite direction. The particulate matter is captured and settled by the droplets. Carbon black and a small amount of sodium sulfide crystals generated in the reaction are deposited at the bottom of the tank and fall into the discharge pipe 10 through the slag discharge port 9. The servo motor drives the spiral feeding rod 11 to rotate, continuously pushing the slag to the discharge port 12 and falling into the slag collection bucket below.

[0016] During equipment installation, the equipment is moved a short distance to the designated location in the workshop using the casters 14. The handwheel of the threaded lifting leg 15 is rotated to raise the support leg 13 as a whole to match the height difference of the workshop floor, ensuring that the exhaust pipe 2 is accurately connected to the subsequent pipeline without the need for additional padding or pipe cutting. After a batch of processing is completed, when cleaning the tank 1, the threaded lifting leg 15 can be used to tilt both ends of the tank 1, making it easier for the final wastewater to be discharged from the liquid outlet pipe 8 and the slag discharge port 9.

[0017] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0018] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0019] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
