Description

Technical Field

[0001] The utility model belongs to the technical field of absorption towers, in particular to a jet sieve plate absorption tower. Background Art

[0002] Absorption tower is a device for realizing absorption operation, which is divided into three categories according to the contact form between gas and liquid. The first category is plate tower, bubbling absorption tower, stirring bubbling absorption tower in which gas is dispersed in liquid phase in the form of bubbles; the second category is ejector, venturi, spray tower in which liquid is dispersed in gas phase in the form of droplets; the third category is packed absorption tower and falling film absorption tower in which liquid contacts gas phase in film-like motion. The flow mode of gas and liquid in the tower can be countercurrent or cocurrent. Countercurrent operation is usually adopted, and the absorbent is added from the top of the tower to flow from top to bottom, contacting with gas flowing from bottom to top, and the liquid that absorbs the absorbent is discharged from the bottom of the tower, and the purified gas is discharged from the top of the tower.

[0003] The absorption tower in the prior art also has the following problems when in use:

[0004] 1. The sieve hole of the sieve plate tower is prone to clogging. Cleaning the sieve hole is cumbersome, which will reduce the working efficiency of the absorption tower and make it inconvenient to use;

[0005] 2. The position of the spray head used to spray the absorption liquid in the absorption tower is fixed, and there will be a dead angle for spraying, which makes it impossible for the air to be purified to fully contact with the absorption liquid.

[0006] The sieve holes of the sieve plate in the prior art are easily clogged during use.

[0007] In view of the above problems, the utility model document proposes a jet sieve plate absorption tower. Utility Model Content

[0008] The utility model aims to provide a jet sieve plate absorption tower, which can drive the shaking component to move when the swing component moves, so as to continuously shake the sieve plate to prevent the sieve plate from being blocked, thereby solving the existing technical problems.

[0009] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0014] and two groups of shaking assemblies used in conjunction with the swing assembly, two fixed blocks are fixed on the surface of the tower body, and the two groups of shaking assemblies are respectively arranged between the two fixed blocks and the tower body for shaking and dredging the two sieve plates;

[0015] Two sets of locking assemblies are respectively arranged in two fixed blocks for releasing the connection between the swing assembly and the two sets of shaking assemblies.

[0016] Optionally, the swing assembly includes a driven gear fixed to the surface of the connecting rotating tube, a half-toothed ring is slidably provided at the bottom end of the fixed frame, a driving rack meshing with the driven gear is fixed at the side end of the half-toothed ring, a half-toothed gear intermittently meshing with the half-toothed ring is rotated at the bottom end of the fixed frame, a second drive motor is fixed to the top end of the fixed frame, and the second drive motor is connected to the half-toothed gear through a coupling.

[0017] Optionally, each group of the shaking components includes two first grooves opened in the fixed block, connecting plates are slid in the two first grooves, vibration rods are fixed at the bottom ends of the two connecting plates, the two vibration rods are intermittently contacted with the top ends of the two sieve plates respectively, a connecting column is slid in the fixed block, the connecting column is fixed between the two connecting plates, a first spring is fixed at the bottom end of the upper connecting plate, the side end of the first spring is fixed in a first groove, and the first spring is sleeved on the surface of the connecting column.

[0019] Optionally, a second spring is fixed to the bottom end of the connecting plate at the lower side, and a side end of the second spring is fixed in one of the first grooves.

[0020] Optionally, each group of the locking assembly includes a second groove opened in the fixed block, a threaded block slides in the second groove, a screw rod rotates in the second groove, the threaded block is threadedly connected to the surface of the screw rod, the threaded block is in contact with the top of the upper connecting plate, and a first drive motor is fixed to the top of the fixed block, and the first drive motor is connected to the screw rod through a coupling.

[0021] In the present application, the second driving motor is started to drive the half-tooth gear to rotate, the rotation of the half-tooth gear drives the half-tooth gear ring to reciprocate at the bottom end of the fixed frame, the half-tooth gear ring drives the driving rack to reciprocate linearly, the reciprocating movement of the driving rack drives the driven gear to swing, the driven gear drives the connecting rotating pipe to swing, the swinging of the connecting rotating pipe drives the connecting plate to swing, the connecting plate drives multiple spray heads located on the lower side of the connecting plate to swing and spray, so that the spraying of the absorption liquid is more uniform;

The connecting plate drives the lower connecting plate to move downward through the connecting column, and the two connecting plates respectively drive the two vibrating rods to move downward to beat the side ends of the two screen plates. When the second semicircular extrusion block leaves the surface of the first semicircular extrusion block, the elasticity of the first spring and the second spring pushes the two connecting plates to reset, and the vibrating rods are driven to beat the surface of the screen plate back and forth, so that the screen plate itself vibrates and does not get blocked.

[0023] When there is no need to shake the screen plate, the first drive motor can be started to drive the screw rod to rotate. The rotation of the screw rod drives the threaded block to move downward, and the threaded block drives the connecting plate to move downward. The downward movement of the connecting plate drives the first semicircular extrusion block to move downward. The downward displacement of the first semicircular extrusion block releases the contact with the second semicircular extrusion block, making it convenient to use.

[0024] In the utility model, the jet sieve plate absorption tower can achieve the effect of driving multiple spray heads to swing and spray through the swing component;

[0025] In the utility model, the jet sieve plate absorption tower can achieve the effect of continuously shaking the sieve plate to prevent the sieve plate from being blocked by shaking the assembly;

[0026] The swing component in the technical solution can drive multiple spray heads to swing and spray, which can effectively reduce the spraying blind spots and enable the air to fully contact the absorption liquid. At the same time, the swing component also drives the shaking component to move during movement, which can continuously shake the screen plate to prevent the screen plate from being blocked.

[0027] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
