Description

Technical Field

[0001] The utility model relates to the technical field of chemical production tail gas treatment, in particular to a safe washing tower with high-efficiency filtering function. Background Art

[0002] The scrubber is a new type of gas purification equipment. It is an improvement on the floating packing layer gas purifier and is widely used in pre-treatment of industrial waste gas purification and dust removal, with good purification effect. For coal gasification process, gas scrubbing is inevitable, and this unit operation is used in all coal gasification technologies. Because its working principle is similar to the scrubbing process, it is named the scrubber.

[0003] The scrubber is similar to the distillation tower, and is composed of a tower body, a tower plate, a reboiler, and a condenser. Since the scrubber is a device for rough separation, the number of tower plates is generally small, usually not more than ten. The scrubber is suitable for separating mixed gases containing a small amount of dust. The components will not react, and the product should be easy to liquefy. Impurities such as dust (also known as high-boiling substances) are not easy to liquefy or solidify. When the mixed gas enters the scrubber from the middle of the scrubber, due to the presence of product component liquid between the tower plates, the product component gas liquefies and evaporates at the same time, while the impurities cannot be liquefied or solidified. When passing through the tower plate with liquid, they will be fixed by the product component liquid, producing a washing effect. The scrubber is designed and manufactured based on this principle.

[0004] As an example of the prior art, referring to patent document CN212942198U, an impurity storage structure of a washing tower water tank and a washing tower are provided. In the impurity storage structure of the washing tower water tank, a liquid outflow outlet is provided on the washing tower water tank, and the direction in which the liquid in the washing tower water tank flows toward the liquid outflow outlet is in the same direction as the axial direction of the liquid outflow outlet; a plurality of pattern plates are sequentially arranged on the bottom surface of the washing tower water tank, and the length direction of each pattern plate is interlaced with the direction in which the liquid in the washing tower water tank flows toward the liquid outflow outlet; there is a gap between one end of all the pattern plates and the inner wall of the washing tower water tank, and all the gaps form a sedimentation channel; a sewage outlet is provided on the washing tower water tank; and a sewage flushing inlet is also provided on the inner wall of the washing tower water tank. All the pattern plates of the utility model form a corrugated structure on the bottom surface of the washing tower water tank. When the liquid is transported through the liquid outflow outlet, the impurities in the liquid cannot move with the water flow and will be stored between two adjacent pattern plates to prevent the impurities from diffusing in the liquid.

[0005] As shown in the above patent, there is no special description of the structure, shape, and arrangement of the nozzle. For the washing tower, the internal space is fixed according to the model. Therefore, parameters such as the nozzle's water jet pressure and spray coverage area will directly affect the filtering, purification, and cooling effects of the exhaust gas treatment.

[0006] Therefore, there is an urgent need for a washing tower with a high-efficiency filtering nozzle to improve the use effect of the washing tower. Summary of the invention

[0041] Embodiment 1

[0042] Reference Figure 1 to Figure 5 A washing tower which is safe and has an efficient filtering function comprises: a tower body 1 which is cylindrical and has a washing chamber 101, and an air inlet 102 and an air outlet 103 which are connected to the washing chamber 101 are provided on the tower body 1, and a liquid storage area 104 is provided at the lower part of the washing chamber 101; a centrifugal pump 2, one end of which is connected to the liquid storage area 104 through a water inlet pipe 201, and the other end of which is connected to the upper end of the washing chamber 101 through a water outlet pipe 202; a spray assembly 3 which is connected to and connected to the water outlet pipe 202; a wire mesh grille 4, a packing area 105 for placing packing is formed between the wire mesh grille 4 and the spray assembly 3. The structural features of the utility model are as follows: the spray assembly 3 includes a cross-shaped spray pipeline 301, a plurality of reversing joints 302 arranged under the spray pipeline 301, and a spray nozzle 303 connected to the reversing joint 302; the spray nozzle 303 is provided with a spiral nozzle 3031, and the size of the spray nozzle 303 is gradually reduced from the top, which plays a role in pressurizing and guiding the water outlet.

[0043] Compared with a single straight-line arrangement of the pipeline, the cross-shaped spray pipeline 301 is more stable in structure and has a wider and more balanced spray coverage area.

[0044] The above content is the basic structural scheme of the utility model, and its working principle is: the exhaust gas enters the washing chamber 101 from the air inlet 102. Because the exhaust gas has a certain temperature, it can naturally rise upward in the washing chamber 101. During the rising process, it is effectively purified and filtered through the filling area 105. The centrifugal pump 2 draws the liquid (generally water) in the liquid storage area 104 upward and sprays it into the washing chamber 101 through the spray assembly 3, which plays a further filtering, purification and cooling role. Finally, the treated gas is discharged from the washing tower from the air outlet 103.

[0045] The advantage of the present invention is that it adopts a special spray component 3, specifically a spray nozzle 303 with a spiral nozzle 3031, so that when the liquid is sprayed, it can be sprayed outward along the spiral nozzle 3031, which can form a multi-level 360-degree spray effect, and the spiral jet flow can accelerate the outflow to improve the spray effect.

[0046] Embodiment 2

[0047] Reference Figure 6 In a preferred embodiment of the utility model, a pressure valve assembly 5 is further provided in the spray assembly 3, and the pressure valve assembly 5 at least includes a closed sealing position state and an open water outlet position state. When water enters the spray assembly 3 and the water pressure reaches a critical value, the pressure valve assembly 5 can be pushed open by the water pressure, thereby switching to the open water outlet position state. At this time, the water circuit is connected, and the spray assembly 3 sprays water outward to purify the gas; once the water pressure drops and is lower than the critical value, the pressure valve assembly 5 automatically switches to the closed sealing position state, so that the spray assembly 3 no longer sprays water outward. Therefore, the utility model can realize automatic control of the opening and closing of the water circuit through the setting of the pressure valve assembly 5, and will not discharge water when the water pressure does not meet the requirements, so that the staff can promptly discover and increase the working power of the centrifugal pump 2, thereby ensuring that the water pressure is high enough, and then the spray effect can meet the use requirements.

[0048] The further configuration of the above embodiment is that the pressure valve assembly 5 includes a sealing plug 501 and a spring 502, the sealing plug 501 is arranged in the reversing joint 302, and the spring 502 acts on the sealing plug 501, so that the sealing plug 501 always has a movement tendency of moving upward and switching to a closed sealing position state. Further, a stepped hole 503 is arranged in the reversing joint 302, and the stepped hole 503 has a large diameter section 5031 and a small diameter section 5032; the sealing plug 501 includes a base 5011 and an outer edge 5012, and a plurality of through holes 5013 are opened on the outer edge 5012. The working principle when in use is as follows:

[0049] When the sealing plug 501 abuts against the small-diameter section 5032, the upper end of the through hole 5013 is blocked, so that the pressure valve assembly 5 switches to a closed sealing position; when the sealing plug 501 separates from the small-diameter section 5032, the upper end of the through hole 5013 is connected, so that the pressure valve assembly 5 switches to an open water outlet position.

[0050] Therefore, the pressure valve assembly 5 composed of the sealing plug 501 and the spring 502 is simple in structure and stable and reliable in use while meeting the functional requirements.

[0051] Embodiment 3

[0052] Based on the structure of any of the above embodiments, this embodiment provides some multifunctional preferred structural solutions, referring to Figures 1 to 8 , as follows:

[0053] 1. A liquid level gauge 6 is also provided on one side of the tower body 1, and the upper and lower ends of the liquid level gauge 6 are respectively connected to the washing chamber 101. During use, the liquid will rise and evaporate continuously, and the washing tower is generally made of invisible metal materials. Therefore, through the setting of the liquid level gauge 6, the liquid level height of the liquid storage area 104 can be observed in time, so that it can be replenished in time after the liquid level drops to ensure the stability of the use effect. In addition, when the liquid absorbs enough waste gas impurities and no longer meets the requirements, the color of the liquid in the liquid storage area 104 can be checked through the liquid level gauge 6, so that it can be replaced in time.

[0054] Furthermore, switch valves 601 are provided at both the upper and lower ends of the liquid level meter 6 , which is equivalent to the liquid level meter 6 having a switch function, so that the staff can selectively open the liquid level meter 6 through the switch valve 601 .

[0055] 2. The tower body 1 is provided with a plurality of detection ports 7, which are distributed at the upper and lower ends of the wire mesh grille 4, and the detection ports 7 are all detachably connected with sealing plugs 701. Through the setting of the detection ports 7, the gas in the washing tower can be sampled and tested externally to determine the working status of the washing tower. In addition, the distribution of multiple detection ports 7 can realize the function of multi-point sampling, so that the test results are more comparative and authentic. When the sampling is completed, the sealing plug 701 is re-covered to seal the detection port 7, thereby preventing internal gas leakage and ensuring the normal operation of the washing tower.

[0056] 3. A ceiling bracket 8 is also fixed on the upper part of the washing chamber 101, and the spray assembly 3 is connected to the ceiling bracket 8. When the spray assembly 3 is in use, water flows through it, and therefore it becomes unstable due to the pressure of the water pressure, causing the spray pipeline 301 to shake or even fall off, and then the equipment is damaged and affects normal use. By using the ceiling bracket 8, an installation position can be provided for the spray assembly 3 to provide a good support effect, balance the impact of the water pressure, and ensure that the spray assembly 3 can be stably suspended in the washing chamber 101 for use.

[0057] 4. In order to facilitate the discharge of the aqueous solution in the liquid storage area 104 , a liquid discharge port 9 is opened on the side wall of the tower body 1 . The liquid discharge port 9 is connected to the liquid storage area 104 , and a manual valve 901 is provided on the liquid discharge port 9 .

[0058] 5. The water inlet pipe 201 and the water outlet pipe 202 are both provided with flanges 10, which play a good connection role. The flange 10 is provided with a sealing gasket 11 to ensure the sealing of the connection. The sealing gasket 11 is provided with a foolproof indicator rib 1101, which can serve as an operation prompt for the operator. Specifically, according to the preset tightness, when the foolproof indicator rib 1101 points to a specific direction, it means that the installation is in place.

[0059] It is worth noting that other technical solutions of the present invention belong to the prior art and will not be described in detail.

[0060] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the concept of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
