Description

Technical Field

[0001] This utility model relates to the technical field of waste gas treatment equipment, and in particular to a two-stage alkaline spray tower. Background Technology

[0002] Alkaline spray towers are widely used equipment in industrial waste gas treatment, mainly for absorbing and purifying harmful gases containing acidic components. Their basic principle is to atomize alkaline liquid through a spray device, allowing it to fully contact the waste gas flowing upwards, resulting in a neutralization reaction and thus purifying the gas.

[0003] However, in actual working conditions, the industrial waste gas to be treated often contains a large amount of dust or particulate matter. If this dust enters the tower directly with the gas without treatment, it will quickly adhere to and clog the internal spray heads, causing the spray liquid to be unable to be sprayed evenly. This results in a sharp reduction in the gas-liquid contact area, severely reducing the purification efficiency of the waste gas, and may even force the entire equipment to be shut down for unblocking.

[0004] To address this issue, existing spray towers typically incorporate a filter at the air inlet to intercept dust particles in the exhaust gas. While this design offers some protection, the filter itself gradually becomes clogged after trapping dust, increasing airflow resistance and necessitating regular disassembly and cleaning.

[0005] In existing technologies, these filters are mostly fixed inside the air intake pipe by bolts or flanges. This fixed structure makes the removal and installation of the filters very cumbersome. Maintenance personnel need to carry tools and go deep into the pipe to operate. Especially in some large equipment or in situations where installation space is limited, disassembly and repositioning are extremely inconvenient and time-consuming, resulting in excessively long equipment downtime maintenance cycles and affecting the continuity of production.

[0006] Therefore, this utility model proposes a two-stage alkaline spray tower to overcome the shortcomings of the prior art. Utility Model Content

The pressing block and the buckle are fixedly connected. The fixing assembly also includes a spring, with both ends of the spring abutting between the two pressing blocks respectively. Under the elastic force of the spring, the buckle is engaged in the groove of the T-shaped slider to lock the interception assembly.

[0011] Preferably, the two-stage alkaline spray tower further includes a fan and a chimney, with the fan connected between the exhaust pipe and the chimney.

[0012] Preferably, the two-stage alkaline spray tower further includes an adjustment mechanism, which is disposed on the water pipe. The adjustment mechanism includes a fixed cover fixed to the water pipe, an adjustment cover rotatably disposed on the fixed cover, and a plurality of sliding blocks rotatably disposed inside the fixed cover.

The adjustment cover is connected to the plurality of sliding blocks in a transmission manner.

[0013] Preferably, a protruding handle is fixedly connected to the upper surface of the adjusting cover.

[0014] Preferably, the adjustment mechanism further includes a pin, and the adjustment cover and the fixed cover are provided with mutually alignable insertion holes, and the pin can be inserted into the mutually alignable insertion holes.

[0036] Based on the above embodiments, the present invention may further include the following preferred technical solutions:

[0040] As another preferred embodiment, in order to achieve the transmission between the adjusting cover 601 and the sliding block 606, please refer to... Figure 3 The adjusting cover 601 has a second slot 605. The adjusting mechanism 6 also includes a locking block 608, one end of which engages with the second slot 605 and the other end is connected to the sliding block 606. The fixed cover 603 has a third slot 609. The adjusting mechanism 6 also includes a connecting block 607, which is fixed to the bottom of the sliding block 606 and slidably engages with the third slot 609.

[0041] As another preferred embodiment, in order to clarify the installation method of the adjustment cover 601, the adjustment cover 601 and the fixed cover 603 are rotatably connected.

[0042] Working principle: When harmful gas containing dust enters through the inlet pipe 201, the filter screen 202 inside the inlet pipe 201 intercepts the dust in the gas. After passing through the filter screen 202, the gas enters the tower body 1. At the same time, the water pump 4 starts, introducing alkaline spray liquid into the regulating mechanism 6 through the water pipe 5, and finally into the interior of the tower body 1. The spray liquid and the gas in the tower body 1 are subjected to flushing absorption and purification. The purified gas enters the fan 8 through the outlet pipe 7 at the top of the tower body 1. Finally, the fan 8 blows the gas out of the chimney 9.

[0043] When the filter screen 202 needs to be removed for cleaning, the operator presses the pressing block 302 along the mounting base 301. The pressing block 302 drives the fixed connection buckle 304 to move synchronously, and together they squeeze the spring 303 until the buckle 304 disengages from the groove of the T-shaped slider 203. The fixing component 3 is then removed, and the lock is released. Then, along the first slot 204 in the air intake pipe 201, the T-shaped slider 203 and the filter screen 202 at the bottom are removed together for cleaning.

[0044] When it is necessary to adjust the flow rate of the spray liquid, hold the protruding handle 602 to drive the adjusting cover 601 to rotate along the rotating connection of the fixed cover 603. The rotation of the adjusting cover 601 drives the second slot 605 on it to rotate synchronously. The second slot 605 drives the locking block 608, and the locking block 608 drives multiple sliding blocks 606 to rotate. The connecting block 607 at the bottom of the sliding block 606 slides along the third slot 609 in the fixed cover 603, which ultimately changes the closed state between the multiple sliding blocks 606, that is, changes the flow area of ​​the inlet 610, thereby adjusting the water volume of the spray liquid. After the adjustment is completed, insert the pin 604 into the sockets on the adjusting cover 601 and the fixed cover 603 that can be aligned with each other to prevent the adjusting cover 601 from rotating.
