With the long-term use of the purification tower, the fillers will scale and affect the use effect. Therefore, the fillers need to be removed for cleaning or replacement. However, since the fillers of the existing purification tower are tightly attached to the inner wall of the tower body, it is not convenient to remove the fillers. Utility Model Content

DETAILED DESCRIPTION

[0031] The present application is further described in detail below in conjunction with the accompanying drawings.

[0032] Reference Figure 1 A glass fiber reinforced plastic purification tower includes a plurality of tower tubes 1 stacked up and down. The tower tubes 1 are made of glass fiber reinforced plastic. A flange 11 is fixed to the end face of the tower tube 1. Adjacent tower tubes 1 are fixed by the flange 11 and bolts. Adjacent flanges 11 are sealed by setting a sealing ring. An air inlet 12 is arranged on the side wall of the bottom tower tube 1, and an air outlet 13 is opened on the top of the top tower tube 1. A packing layer 2 is arranged on the inner wall of the tower tube 1. Multiple groups of packing layers 2 are arranged in the vertical direction. The packing layer 2 is generally made of polymer material. The complex shape makes it have a large surface area. The packing layer 2 is formed by stacking multiple layers of polymer material.

[0033] A water tank 14 is fixed at the bottom of the bottom tower 1, and a water pump 15 is installed on the water tank 14. An annular spray pipe 16 is fixed in the tower 1, and a plurality of nozzles 17 are evenly arranged at the bottom of the spray pipe 16. The water inlet of the water pump 15 is connected with the water tank 14, and the water outlet of the water pump 15 is connected with the spray pipe 16 through a pipeline. The water pump 15 pumps the alkali solution in the water tank 14 into each spray pipe 16, and then the alkali solution is sprayed from the nozzle 17 onto the packing layer 2 below, absorbing the harmful gas passing through, and the alkali solution falls back into the water tank 14, thereby forming a cycle. The alkali solution in the water tank 14 needs to be replaced regularly.

[0034] Reference Figure 1 and Figure 2 A plurality of support blocks 10 are fixed to the inner wall of the tower 1 along the circumferential direction, a support ring 3 is placed on the support block 10, a support net 31 is fixed to the inner ring wall of the support ring 3, a packing layer 2 is placed on the support ring 3 and the support net 31, and the outer wall of the packing layer 2 is in close contact with the inner wall of the tower 1. The packing layer 2 can be stably supported by the support net 31, and the support net 31 has excellent air permeability, which is convenient for gas and liquid to pass through. The support net 31 is preferably a stainless steel net. The packing layer 2 is in close contact with the inner wall of the tower 1, which, on the one hand, achieves an accurate positioning effect, and on the other hand, prevents the gas from moving upward without passing through the packing layer 2.

[0035] When the packing layer 2 is placed on the support block 10 through the support ring 3, the top surface of the packing layer 2 is higher than the top surface of the tower 1. This arrangement allows the packing layer 2 located below to be inserted into the upper tower 1 when the upper tower 1 is hoisted, thereby achieving a positioning effect. On the other hand, it also facilitates the upward removal of the packing layer 2.

[0036] A suspension rod 4 is inserted at the top of the packing layer 2, a suspension hook 41 is fixed at the top of the suspension rod 4, and the bottom end of the suspension rod 4 penetrates the packing layer 2 and is threadedly connected to the support ring 3. At least two suspension rods 4 are provided along the circumference of the support ring 3, and the plurality of suspension rods 4 are evenly distributed along the circumference of the support ring 3. In this embodiment, the number of suspension rods 4 is specifically four, and the suspension rods 4 are all vertically arranged. The top surface of the support ring 3 is provided with threaded holes for the bottom end of the suspension rod 4 to be threadedly connected. Through the suspension rod 4 and the suspension hook 41, it is convenient to take out the support ring 3 together with the packing layer 2, and it is convenient to disassemble and assemble.

[0037] Reference Figure 2 and Figure 3The top of the suspension rod 4 is threadedly connected to a limit block 42, which is located below the hook 41. The bottom surface of the limit block 42 contacts the top surface of the packing layer 2. By rotating the limit block 42, the limit block 42 can be moved along the suspension rod 4. The limit block 42 has a pressing effect on the packing layer 2 to prevent the packing layer 2 from separating under the action of the airflow. It should be noted that the limit block 42 is first threadedly connected to the top of the suspension rod 4, and the hook 41 is then welded and fixed to the top of the suspension rod 4, so that the limit block 42 and the suspension rod 4 can be assembled.

[0038] The limit block 42 is a regular polygonal block. The regular polygonal limit block 42 is easy to turn with a wrench and can also be turned directly by hand. The number of polygons of the limit block 42 is consistent with the number of the suspension rods 4. Each side wall of the limit block 42 is provided with a slot 43, and the slot 43 penetrates the limit block 42 in the vertical direction. A connecting rod 44 is provided between adjacent limit blocks 42. The two ends of the connecting rod 44 are respectively plugged into the slots 43 on the surfaces facing each other of the adjacent limit blocks 42. The connecting rod 44 is installed after the limit block 42 is rotated to a certain angle. The weight of the connecting rod 44 improves the pressing effect on the top surface of the packing layer 2, and the connecting rod 44 is plugged into the slot 43 to prevent the threaded connection position of the limit block 42 from loosening.

[0039] The implementation principle of the FRP purification tower of the present application is: harmful gases are introduced into the purification tower from the air inlet 12, and the harmful gases are discharged from the tower body from the air outlet 13 after passing through multiple packing layers 2 in sequence. During this process, the alkaline solution sprayed by the nozzle 17 reacts and absorbs the components in the harmful gases.

[0040] When the packing layer 2 has been used for too long and needs maintenance, after unscrewing the bolts on the flange 11, use the lifting equipment to lift the tower 1 in turn, and then use the lifting rope to connect the hook head of the lifting equipment to the multiple hooks 41 on the corresponding packing layer 2 at the same time. The support ring 3 together with the packing layer 2 can be directly lifted out of the tower 1 by lifting. The method of installing the packing layer 2 into the tower 1 is similar. It is relatively simple for the packing layer 2 to enter and exit the tower 1, and the packing layer 2 is firmly supported by the support ring 3 and the support net 31, and the lifting stability is good.

[0041] After the packing layer 2 is lifted out of the tower 1, first move the connecting rod 44 upward to separate its two ends from the limit blocks 42, then drive the hanging rod 4 to rotate by rotating the hook 41, so that the lower end of the hanging rod 4 is disconnected from the threaded connection with the support ring 3, and then pull the hanging rod 4 upward to replace or clean the packing layer 2.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
