Description

Technical Field

[0001] The utility model relates to the technical field of gas tail gas, and particularly relates to an industrial gas tail gas absorption device. Background Art

[0002] Industrial gas tail gas absorption technology is widely applied in many industrial production fields such as chemical industry, metallurgy, garbage incineration, etc. Through industrial gas tail gas absorption equipment, the emission of harmful substances in waste gas can be greatly reduced, thus protecting the environment and human health. Reference can be made to the patent publication number: CN 216149398 U - a Chinese utility model patent for an industrial gas tail gas absorption device. This patent processes tail gas through a filter box. However, there is only one tail gas treatment process in the above patent, resulting in low tail gas treatment efficiency and difficulty in achieving the purification purpose. Content of the Utility Model

[0003] The main purpose of the utility model is to provide an industrial gas tail gas absorption device to solve the problem that the existing industrial gas tail gas absorption device has only one tail gas treatment process with low efficiency and difficulty in achieving the purification purpose.

[0004] To achieve the above purpose, the utility model provides an industrial gas tail gas absorption device, which includes a delivery pipe, a cooling tank, a primary treatment tank, a blower, and a secondary treatment box;

[0005] The delivery pipe is connected in series with the cooling tank, the primary treatment tank, the blower, and the secondary treatment box along the way;

[0006] A first mesh plate is horizontally arranged in the primary treatment tank. The first mesh plate divides the primary treatment tank into an upper cavity and a lower cavity. The inlet end of the delivery pipe is connected to the upper cavity, and the outlet end is connected to the lower cavity. Adsorption particles are laid on the first mesh plate;

[0007] A plurality of polypropylene fiber plates are arranged at intervals in the secondary treatment box along the waste gas transmission direction.

[0008] Preferably, a collection hood is connected to the initial end of the delivery pipe.

[0009] Preferably, a second mesh plate is fixedly arranged at the inlet end of the collection hood.

[0010] Preferably, a switch door is detachably arranged on one side of the primary treatment tank. Slots are arranged on both sides of the cooling tank along its length direction, and the first mesh plate is inserted into the two slots.

[0011] Preferably, the metal beads are steel beads.

[0012] Preferably, the adsorption particles are activated carbon particles.

[0013] Preferably, a water inlet pipe and a water outlet pipe are connected to the cooling tank, and the delivery pipe located in the cooling tank is in a spiral structure.

[0014] Preferably, a layer of metal beads is laid on the first wire mesh plate, and adsorption particles are laid on the metal beads.

[0015] The beneficial effects of the above solution are as follows:

[0016] The driving blower starts to work, and the tail gas first enters the cooling tank through the delivery pipe. The cooling tank cools the tail gas in the delivery pipe. Among them, in tail gas treatment technologies such as adsorption, there is an optimal working temperature range. If the tail gas temperature is too high, the treatment efficiency of these technologies may be reduced. By lowering the temperature, the waste gas temperature can be controlled within an appropriate range, thereby improving the treatment efficiency. Further, the tail gas enters the upper cavity, and the tail gas sequentially passes through the adsorption particles, metal beads, and the first wire mesh plate and enters the lower cavity. When the tail gas passes through the adsorption particles, the adsorption particles perform the first purification treatment on the harmful substances in the tail gas. Further, the tail gas passes through the lower cavity and the blower and enters the secondary treatment box, and the tail gas passes through multiple polypropylene fiber plates to form the second purification treatment. The tail gas treatment efficiency and purification effect are greatly improved through two purifications.

[0017] Among them, a layer of metal beads is laid on the first wire mesh plate. The aperture of the first wire mesh plate is relatively large. Assuming that the adsorption particles are directly placed on the first wire mesh plate, the adsorption particles will pass through the first wire mesh plate and leak into the lower cavity. By laying a layer of metal beads, the above situation is avoided. The tail gas sequentially passes through the adsorption particles, metal beads, and the first wire mesh plate and enters the lower cavity. In addition, it is easy to replace the adsorption particles by laying the adsorption particles on the metal beads. Description of the Drawings

Many specific details are set forth in the following description in order to fully understand the present utility model, but the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below. Embodiment

[0032] As Figures 1 to 4 shown, this embodiment provides an industrial gas tail gas absorption device, including a conveying pipe 1, a cooling tank 2, a primary treatment tank 3, a blower 4 and a secondary treatment tank 5. The conveying pipe 1 is connected in series with the cooling tank 2, the primary treatment tank 3, the blower 4 and the secondary treatment tank 5 along the way. As Figure 2 shown, a collection hood 6 is connected to the initial end of the conveying pipe 1. A second mesh plate 61 is fixedly arranged at the air inlet end of the collection hood 6. The second mesh plate 61 is arranged to prevent larger sundries from being adsorbed into the conveying pipe 1. A first mesh plate 31 is horizontally arranged in the primary treatment tank 3. The first mesh plate 31 divides the primary treatment tank 3 into an upper chamber 32 and a lower chamber 33. The air inlet end of the conveying pipe 1 is communicated with the upper chamber 32, and the air outlet end of the conveying pipe 1 is communicated with the lower chamber 33. A layer of metal beads 34 is laid on the first mesh plate 31. The metal beads 34 are steel beads. Adsorption particles are laid on the metal beads 34. The adsorption particles are activated carbon particles. A plurality of polypropylene fiber plates (not shown) are arranged at intervals in the secondary treatment tank 5 along the waste gas transmission direction. Among them, a layer of metal beads 34 is laid on the first mesh plate 31. The aperture of the first mesh plate 31 is relatively large. Assuming that the adsorption particles are directly placed on the first mesh plate 31, the adsorption particles will directly pass through the first mesh plate 31 and leak into the lower chamber 33. By laying a layer of metal beads 34, the above situation is avoided. The tail gas sequentially passes through the adsorption particles, the metal beads 34, and the first mesh plate 31 and enters the lower chamber 33.

[0033] The driving blower 4 is started to work, and the tail gas first enters the cooling tank 2 through the conveying pipe 1. The cooling tank 2 cools the tail gas in the conveying pipe 1. Among them, in the tail gas treatment technology, when encountering high-temperature tail gas, it is necessary to cool down to avoid the activated carbon from heating up and catching fire. Further, the tail gas enters the upper chamber 32, and the tail gas sequentially passes through the adsorption particles, the metal beads 34, and the first mesh plate 31 and enters the lower chamber 33. When the tail gas passes through the adsorption particles, the adsorption particles perform the first purification treatment on the harmful substances in the tail gas. Further, the tail gas passes through the lower chamber 33 and the blower 4 and enters the secondary treatment box 5, and the tail gas passes through a plurality of polypropylene fiber plates to form the second purification treatment. The tail gas treatment efficiency and the purification effect are greatly improved through the two-stage purification.

[0034] The polypropylene fiber plate is made of continuous polypropylene fibers and has a porous structure and a large specific surface area, which makes it an effective filtering medium. Due to its fine fiber diameter and dense arrangement, the polypropylene fiber plate can capture and block fine particles such as dust, smoke, and other suspended substances, thereby purifying the tail gas.

[0035] A switch door 35 is detachably arranged on one side of the primary treatment tank 3. Slots (not shown) are provided on both sides of the cooling tank 2 along its length direction, and the first mesh plate 31 is inserted into the two slots. This facilitates the replacement of the adsorption particles.

[0036] The cooling tank 2 is connected with a water inlet pipe 7 and a water outlet pipe 71, and the conveying pipe 1 located in the cooling tank 2 has a spiral structure 11.

[0037] Preferably, the aperture of the first mesh plate 31 is 1 cm, the diameter of the steel beads 34 is 4 cm, and the particle size of the activated carbon particles is 2 cm.

[0038] In another embodiment, the steel beads 34 are not provided on the first mesh plate 31, and only the activated carbon particles are provided.

[0039] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
