[0002] A flue gas collection device is a collection unit for pollution sources in a flue gas purification system. It can guide dust and gaseous pollutants into the purification system while preventing them from spreading into the production workshop and the atmosphere, thus preventing pollution. Traditional flue gas collectors are inconvenient to move, causing inconvenience for personnel to use, and most flue gas collectors are not easy to adjust in terms of collection position, making it difficult for the device to collect flue gas from different locations. Therefore, a mobile flue gas collector is proposed to address the above problems. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this utility model provides a novel flue gas collection device.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] This utility model discloses a novel flue gas collection device, comprising a base with wheels at the bottom, a vertically upward-facing frame on one side of the base, a downward-facing smoke collection hood mounted on the frame via a lifting frame, a water curtain adsorption mechanism and a suction fan on the base, the water curtain adsorption mechanism comprising a box on the base, a liquid storage tank at the top of the box, a collection tank below the liquid storage tank, and an air duct between the liquid storage tank and the collection tank, an air inlet pipe and an air outlet pipe at both ends of the air duct, the air inlet pipe being connected to the air outlet of the smoke collection hood via a guide pipe, and the air outlet pipe being connected to the air inlet of the suction fan, a strip-shaped liquid outlet at the bottom of the liquid storage tank, a water curtain passing through the strip-shaped liquid outlet and hanging down to the bottom of the collection tank inside the liquid storage tank, and a pump pipe for pumping the adsorbent in the collection tank into the liquid storage tank.

The straight frame is provided with a drive motor that drives the lead screw to rotate.

[0007] As a preferred technical solution of this utility model, the storage tank is equipped with a level gauge, and the outside of the box is equipped with a controller. The level gauge and the circulation pump in the pump pipe are both connected to the controller. When the level gauge detects that the liquid level of the adsorbent in the storage tank reaches the replenishment value, the controller controls the circulation pump to work and pump the adsorbent in the collection tank into the storage tank.

[0008] As a preferred technical solution of this utility model, the strip-shaped liquid outlet is provided in multiple ways, and each strip-shaped liquid outlet is provided with a water curtain.

[0017] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0018] Example: Figure 1 , Figure 2 , Figure 3 As shown, this utility model discloses a novel flue gas collection device, comprising a base 1 with wheels 2 at the bottom, a vertically upward-facing frame 3 on one side of the base 1, a downward-facing smoke collection hood 5 mounted on the frame 3 via a lifting frame 4, a water curtain adsorption mechanism 6 and a suction fan 7 on the base 1, and the water curtain adsorption mechanism 6 including a housing 8 mounted on the base 1, with a liquid storage tank 9 at the top of the housing 8, and a collection tank 10 located below the liquid storage tank 9. A duct 11 is formed between the two sides, and the box body 8 is provided with an air inlet pipe 12 and an air outlet pipe 13 at both ends of the duct 11. The air inlet pipe 12 is connected to the air outlet end of the smoke hood 5 via a guide pipe, and the air outlet pipe 13 is connected to the air inlet end of the suction fan 7. The bottom of the liquid storage tank 9 is provided with a strip-shaped liquid outlet 14, and the liquid storage tank 9 is provided with a water curtain 15 that passes through the strip-shaped liquid outlet 14 and hangs down to the bottom of the liquid collection tank 10. The liquid collection tank 10 is provided with a pump pipe 16 that pumps the adsorbent liquid in the liquid collection tank 10 into the liquid storage tank 9. It can move freely, allowing it to be moved to areas where smoke collection is needed, thus providing strong flexibility. This utility model uses a specific water curtain 15 type adsorption mechanism 6 to adsorb harmful gases in the flue gas. A duct 11 is formed between the liquid storage tank 9 and the liquid collection tank 10, and a water curtain 15 is also provided between the liquid storage tank 9 and the liquid collection tank 10. In this way, the adsorbent in the liquid storage tank 9 flows down along the water curtain 15 to form a water curtain. Under the adsorption action of the suction fan 7, the flue gas passes through the water curtain. In this way, the adsorbent can adsorb the harmful components in the flue gas, preventing them from spreading into the surrounding environment. It also has the characteristics of simple structure. The liquid collection tank 10 is equipped with a pump pipe 16 to pump the adsorbent in the liquid collection tank 10 into the liquid storage tank 9, thus realizing the recycling of the adsorbent.

[0019] The lifting frame 4 includes a vertically arranged lead screw 17 and a guide rod 18 mounted on a straight frame 3. The lead screw 17 is provided with a moving block 19 that moves along the lead screw 17, and the guide rod 18 is provided with a movable block 20 that moves along the guide rod 18. A lifting frame 21 is installed between the moving block 19 and the movable block 20, and the smoke hood 5 is fixed on the lifting frame 21. The straight frame 3 is provided with a drive motor that drives the lead screw 17 to rotate, which facilitates the height adjustment of the smoke hood 5 to meet different smoke collection needs.

[0020] The storage tank 9 is equipped with a level gauge 22, and the external part of the housing 8 is equipped with a controller. The level gauge 22 and the circulation pump in the pump pipe 16 are both connected to the controller. When the level gauge 22 detects that the liquid level of the adsorbent in the storage tank 9 has reached the replenishment value, the controller controls the circulation pump to work and pump the adsorbent in the collection tank 10 into the storage tank 9. This circulation replenishment avoids insufficient adsorbent in the storage tank 9, which would result in incomplete adsorption.

[0021] The strip-shaped liquid outlet 14 is provided in multiple ways, and each strip-shaped liquid outlet 14 is provided with a water curtain 15, so as to carry out multiple adsorption and ensure a good adsorption and purification effect.

[0022] The exhaust duct 13 is equipped with a flue gas sensor 23. When the flue gas sensor detects that the adsorbed flue gas has reached the alarm value, the concentration of the surface adsorption liquid is lower than the usage requirements, thus reminding the staff to replace the adsorption liquid in time.

[0023] During operation, this novel flue gas collection device can move freely to the area where smoke needs to be collected, thus exhibiting strong flexibility. This invention utilizes a specific water curtain 15-type adsorption mechanism 6 to adsorb harmful gases in the flue gas. A duct 11 is formed between the storage tank 9 and the collection tank 10, and a water curtain 15 is also installed between them. The adsorbent in the storage tank 9 flows down the water curtain 15, forming a water curtain. Under the adsorption action of the suction fan 7, the flue gas passes through the water curtain. This utilizes the adsorbent to adsorb harmful components in the flue gas, preventing them from spreading into the surrounding environment. It also features a simple structure. The collection tank 10 is equipped with a pump pipe 16 that pumps the adsorbent from the collection tank 10 into the storage tank 9, thus enabling the recycling of the adsorbent.

[0024] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
