Description

Technical Field

[0001] This utility model relates to the field of gas treatment equipment technology, and in particular to a novel demister. Background Technology

[0002] A demister is a device used to separate liquid droplets (or air bubbles) entrained in gas. Its core function is to remove tiny liquid droplets suspended in the gas flow, preventing liquid from being lost with the gas, contaminating the equipment, or affecting subsequent processes. It is widely used in chemical, petroleum, pharmaceutical, and environmental protection fields. Its basic principle is to use gravity, inertial force, centrifugal force, or filtration to cause the liquid droplets (usually ranging in diameter from a few micrometers to hundreds of micrometers) entrained in the gas to aggregate, collide, and grow, eventually settling or adhering to the surface of the equipment, thereby separating them from the gas.

[0003] In the production industry of cathode materials for new energy batteries, electrolytic cobalt and nickel production workshops are required. During production in these workshops, a large amount of acid mist is generated, which needs to be collected and treated before it disperses. Current treatment methods generally involve separating the liquid entrained in the gas using a demister after collection. Existing demisters require regular maintenance after prolonged use. Most existing demisters have a maintenance cover on top for opening during maintenance to remove the main functional component, the wire mesh assembly, for easy inspection and maintenance. However, in actual use, due to the acidic environment and the complex composition of the liquid to be separated, the outer frame of the wire mesh assembly may become stuck to the demister body due to corrosion or sedimentation, making it difficult to remove the wire mesh assembly smoothly. Excessive pulling force may also damage the wire mesh assembly or the demister body, indicating room for further improvement. Utility Model Content

[0004] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art and to provide a new type of demister that solves one of the aforementioned problems.

[0005] To achieve the above objectives, this utility model provides a novel demister, comprising a demister housing, a first connecting shell and a second connecting shell fixedly connected to both sides of the demister housing, an inlet pipe and a outlet pipe fixedly connected to the ends of the first connecting shell and the second connecting shell away from the demister housing, a recovery trough provided below the demister housing, an inclined groove provided above the recovery trough near the outlet pipe, and side wall limiting frames fixedly connected to both sides above the inclined groove of the demister housing, with a demister mesh assembly provided between the two side wall limiting frames; The defogging wire mesh assembly includes a wire mesh frame, a wire mesh body, a lever movable plate, a lifting handle, and a hanging flange. The wire mesh body is located inside the wire mesh frame. The two sides of the wire mesh frame are slidably connected to the corresponding side wall limiting frames. The two top edges of the wire mesh frame are rotatably connected to lever movable plates. The two ends of the lever movable plates that protrude from the wire mesh frame are provided with hanging flanges. The two ends of the lifting handle are flexibly connected to the middle of the two lever movable plates away from the hanging flanges by soft ropes.

[0006] Furthermore, the side wall limiting frame has a U-shaped structure with a U-shaped cavity that runs vertically through it, and the two sides of the wire mesh frame are arranged inside the U-shaped cavity to form a channel for vertical sliding.

[0007] Furthermore, the lever movable plate and the suspension flange are integrally formed. A movable groove is provided at the contact point between the lever movable plate and the suspension flange. A latch is provided in the movable groove. The latch is fixedly connected to the top of the wire mesh frame. The latch has a rotatable end, which enables rotatable connection with the lever movable plate. The latch and the movable groove cooperate to form a lever fulcrum.

[0008] Furthermore, the top of the wire mesh frame includes a horizontal section in the middle and inclined sections at both ends of the horizontal section. The buckle is located at the end of the horizontal section and at the contact point between the horizontal section and the inclined section. The suspension flange is correspondingly provided with the inclined section.

[0009] Furthermore, both the feed pipe and the discharge pipe are provided with a connecting flange at the end away from the demister housing.

[0010] Furthermore, a magnetic level gauge is installed on one side of the demister housing at a position corresponding to the recovery tank, and a wire mesh support frame is fixedly connected to the inside of the demister housing near the discharge pipe.

[0011] Furthermore, an inspection channel is provided above the demister housing, and an inspection cover is fixedly connected above the inspection channel. An acid-resistant rubber pad is provided at the lower edge of the inspection cover.

[0012] Furthermore, a recycling pipe interface is provided at the lower center of the recycling tank. The end of the recycling pipe interface away from the recycling tank is fixedly connected to a recycling pump via a flange and a pipe, and the discharge end of the recycling pump is connected to a waste liquid recycling system.

[0013] Furthermore, two level gauge flanges are vertically spaced on the side of the demister housing, and the level gauge flanges are located at the bottom of the recovery tank. The two level gauge flanges are fixedly connected to the inlet and outlet ends of the magnetic float level gauge, respectively.

[0014] Furthermore, both of the suspension flanges are positioned above the side wall limiting frame and cover the top of the side wall limiting frame.

[0015] The above solution has at least one of the following beneficial effects: 1. This utility model is equipped with a defoaming wire mesh assembly, which, in conjunction with the side wall limiting frame, can be hung on the side wall limiting frame via the two protruding hanging flanges at the top during installation. During maintenance, the long end of the lever movable plate can be raised by pulling the handle, and the hanging flange at the short end can be forced downward through the lever principle. This significantly increases the movement force between the wire mesh frame and the side wall limiting frame in the initial stage without increasing the overall lifting force, reducing the impact of attached debris on the demister wire mesh assembly and enhancing the practicality of the device.

[0016] 2. This utility model, through the connection structure between the magnetic level gauge and the demister body, can intuitively and in real time monitor the amount of liquid accumulation, avoiding the decrease in separation efficiency due to excessive liquid accumulation or the gas leakage due to insufficient liquid accumulation, thereby improving operational stability and enhancing the practicality of the device.

A recovery pipe interface 8 is provided in the middle of the lower part of the recovery tank 6. A recovery pump is fixedly connected to the end of the recovery pipe interface 8 away from the recovery tank 6 via a flange and a pipe. The outlet end of the recovery pump is connected to a waste liquid recovery system. An inclined groove 7 is provided at the upper end of the recovery tank 6 near the outlet pipe 4 to facilitate the flow of liquid separated by the wire mesh into the recovery system. Inside the tank 6, a magnetic level gauge 10 is installed at a position corresponding to the recovery tank 6 on one side of the demister housing 1. Two level gauge flanges 9 are arranged vertically on the side of the demister housing 1, and the level gauge flanges 9 are located on the side of the recovery tank 6. The two level gauge flanges 9 are fixedly connected to the inlet and outlet ends of the magnetic level gauge 10 respectively to form a communicating vessel structure. Through the communication structure between the magnetic level gauge 10 and the demister body 1, the amount of liquid accumulation can be monitored intuitively and in real time, avoiding the decrease in separation efficiency due to excessive liquid accumulation or the gas leakage due to insufficient liquid accumulation, thus improving the operational stability. A maintenance channel 11 is provided above the demister housing 1, and a maintenance cover plate 15 is fixedly connected above the maintenance channel 11. An acid-resistant rubber pad is provided at the lower edge of the maintenance cover plate 15. A wire mesh support frame 12 is fixedly connected to the inside of the demister housing 1 near the discharge pipe 4. Side wall limiting frames 13 are fixedly connected to both sides of the demister housing 1 above the inclined chute 7. A demister wire mesh assembly 14 is arranged between the two side wall limiting frames 13. The demister wire mesh assembly 14 includes a wire mesh frame 141, a wire mesh body 142, a lever movable plate 143, a lifting handle 144, and a hanging flange 145. The wire mesh body 142 is located inside the wire mesh frame 141. The two sides of the wire mesh frame 141 are slidably connected vertically to the corresponding side wall limiting frames 13. The side wall limiting frames 13 are structured as follows: Figure 7 As shown. Lever movable plates 143 are rotatably connected to both sides of the top edge of the wire mesh frame 141. The lever movable plates 143 have movable grooves 17. A latch 18 is located above the movable grooves 17 on the top of the wire mesh frame 141. The latch 18 is fixedly connected to the top of the wire mesh frame 141 and has a rotatable end, through which it is rotatably connected to the lever movable plates 143. The latch 18 and the movable grooves 17 cooperate to form a lever fulcrum. (See related structural references.)
