DETAILED DESCRIPTION

[0028] The following will clearly and completely describe the technical solutions of the present invention in conjunction with specific embodiments. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0029] Reference Figure 1-3, a wet method for removing pollutants from flue gas of a glass kiln, comprising a treatment tank 1, a storage tank 2, a water storage tank 3, an air intake pipe 11, an exhaust pipe 4, a water pump 51 and a hollow plate 12, the air intake pipe 11 and the exhaust pipe 4 are both fixedly mounted on the treatment tank 1, a plurality of through holes are provided on the top inner wall of the hollow plate 12 and are arranged in the treatment tank 1, the air intake pipe 11 passes through the treatment tank 1 and extends upward from the center position of the bottom of the treatment tank 1 into the treatment tank 1 and is fixedly connected to the hollow plate 12, and the air intake pipe 11 and the hollow plate 12 are kept in communication, which can achieve the purpose of controlling the air intake to a certain extent. The pipe 11 is injected into the treatment tank 1 for preliminary cooling of the flue gas to be treated. The storage tank 2 and the water tank 3 are respectively fixedly installed with a connecting pipe 1 21 and a connecting pipe 2 31, and the storage tank 2 and the water tank 3 are connected to the treatment tank 1 through the connecting pipe 1 21 and the connecting pipe 2 31, respectively. A slag discharge pipe 22 is fixedly installed on the storage tank 2, and a hollow plate 2 5 is rotatably installed on the exhaust pipe 4. A plurality of spray heads are fixedly installed on the inner wall of the bottom side of the hollow plate 2 5, which can spray the flue gas floating in the treatment liquid below. One end of the exhaust pipe 4 is rotatably installed with a bottom opening and connected to the exhaust pipe 4. The shell 41 is connected to the hollow plate 2 5, and the water pump 51 is fixedly installed on the outside of the treatment tank 1. The water inlet and outlet of the water pump 51 are respectively fixedly installed with a water pumping pipe 52 and a delivery pipe 53, and the water pumping pipe 52 is connected to the water storage tank 3. A circular opening is opened in the center of the top side of the hollow plate 2 5, and the delivery pipe 53 extends into the circular opening at one end away from the water pump 51. A sealing ring 54 for movable sealing at the top of the hollow plate 2 5 is fixedly installed on the delivery pipe 53, which can ensure that the delivery pipe 53 delivers the treatment liquid in the water storage tank 3 to the hollow plate 2 5, and at the same time can ensure that the spray head During normal spraying operation, two porous plates 13 are fixedly installed in the treatment tank 1. The two porous plates 13 are respectively located on the upper and lower sides of the hollow plate 12, and the connecting pipe 1 21 and the connecting pipe 2 31 are respectively located above and below the lower porous plate 13. The upper porous plate 13 can slow down the rising speed of the flue gas in the treatment liquid, and the porous plate 13 arranged at the bottom can reduce the impact of the flue gas on the sediment in the treatment tank 1 when it is injected into the treatment liquid without affecting the downward sedimentation of the solid sediment, and at the same time, it can prevent the residual solid debris on the lower porous plate 13 from submerging the connecting pipe 2 31.

[0030] In this embodiment, in order to obtain a rotational driving force for the hollow plate 2 5 and enable the multiple spray heads on the hollow plate 2 5 to re-treat the flue gas emerging from the treatment liquid by a rotary spraying method, fan blades 42 are fixedly installed on the inner wall of the shell 41.

[0031] In this embodiment, in order to intercept and filter the moisture in the exhaust pipe 4 when exhausting the gas, a dehumidification filter plate 43 with a spherical surface is fixedly mounted on the inner wall of the shell 41 .

[0032] In this embodiment, in order to further reduce the moisture in the exhaust flue gas and effectively collect the moisture, the part of the exhaust pipe 4 located outside the treatment tank 1 is provided with a downward U-shaped bend, and a collection tank 401 is installed on the exhaust pipe 4 with a sealing thread, and the collection tank 401 is set at the lowest point of the U-shaped bend.

[0033] In this embodiment, in order to prevent solid debris from entering the water storage tank 3 through the second connecting pipe 31 and at the same time not affect the backflow of the treated liquid into the water storage tank 3, a spherical mesh plate 311 adapted to the second connecting pipe 31 is fixedly installed on the inner wall of the treatment tank 1.

[0034] In this embodiment, in order to ensure that the settled debris flows into the storage tank 2 by itself, the bottom inner wall of the processing tank 1 is set to be low on the left and high on the right, and the connecting pipe 21 is located at the lowest point of the bottom inner wall of the processing tank 1.

[0035] In this embodiment, in order to facilitate intuitive observation of the amount of treatment liquid in the treatment tank 1, a transparent glass tube 101 arranged in an E shape is fixedly installed on the treatment tank 1, and the two lower ports of the transparent glass tube 101 are respectively located on the upper and lower sides of the porous plate 13 below.

[0036] Working principle: When in use, first turn on the power and inject an appropriate amount of treatment liquid into the water storage tank 3, then keep the treatment tank 1 connected with the glass kiln flue gas exhaust port through the air inlet pipe 11 and start the water pump 51. The treatment liquid in the water storage tank 3 is sucked into the water pump 51 through the suction pipe 52, and then transported to the hollow plate 2 5 through the delivery pipe 53, and then evenly sprayed into the treatment tank 1 through the multiple spray heads on the hollow plate 2 5. When the air inlet pipe 11 introduces the flue gas generated by the glass kiln into the treatment tank 1, the flue gas is first implanted into the treatment liquid through the multiple through holes of the hollow plate 12 for treatment.

[0037] The flue gas comes into contact with the treatment liquid in the treatment tank 1, and the pollutants therein are absorbed or adsorbed by the treatment liquid to achieve wet removal. Since two porous plates 13 are installed in the treatment tank 1, the flue gas will be delayed by the upper porous plate 13 during the rising process, causing the floating speed to be slowed down, thereby increasing the contact time with the treatment liquid and thus improving the removal efficiency. At the same time, the lower porous plate 13 can also prevent the solid precipitate from sinking to the bottom inner wall of the treatment tank 1 and being affected by the treatment liquid disturbed by the flue gas, thereby ensuring the stable sedimentation of the precipitate.

[0038] The treated flue gas continues to rise and is further sprayed through the spray head of the hollow plate 2 5 to ensure that the residual pollutants in the flue gas are completely removed. The treated flue gas then enters the exhaust pipe 4, and the fan blades 42 in the shell 41 drive the hollow plate 2 5 to rotate, realizing rotary spraying and further improving the treatment effect.

[0039] In the exhaust pipe 4, the dehumidification filter plate 43 intercepts and filters out most of the moisture in the flue gas, reducing moisture emissions. At the same time, due to the U-shaped bend design on the exhaust pipe 4, the moisture in the flue gas will condense here and flow into the collection tank 401, realizing effective collection of moisture.

[0040] The spherical mesh plate 311 at the bottom of the treatment tank 1 is set to prevent solid debris from entering the water storage tank 3, while allowing the treatment liquid to flow back freely. The precipitated debris will naturally flow into the storage tank 2 due to the inclined design of the bottom of the treatment tank 1, which is convenient for subsequent cleaning and treatment. The transparent glass tube 101 is set so that the operator can intuitively observe the water level of the treatment liquid in the treatment tank 1, ensuring the normal operation of the entire device, realizing the effective removal of pollutants in the glass kiln flue gas, and achieving the goals of environmental protection and energy saving.

[0041] The above describes in detail the wet-process removal device for glass furnace flue gas pollutants provided by the present invention. This article uses specific examples to illustrate the principles and implementation methods of the present invention. The description of the above examples is only intended to help understand the method and core concept of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications also fall within the scope of protection of the claims of the present invention.
