Description

Technical Field

[0001] The utility model relates to the technical field of graphite tower circulation purification, in particular to a device for graphite tower circulation purification using a multi-layer filter membrane. Background Art

[0002] Graphite tower is a tower equipment made of graphite material for gas-liquid or liquid-liquid mass transfer. Graphite material has strong corrosion resistance, but is limited by the strength of the material. Graphite towers generally have thicker walls, smaller pressure bearing capacity and inner diameter. Graphite towers can be divided into two categories according to their structure: packed towers and plate towers.

[0003] The existing negative pressure energy-saving graphite tower with recyclable purification for treating furnace exhaust gas (Announcement No.: CN112807970B) has at least the following disadvantages: the device filters through the second filter membrane body, the first filter membrane body and the third filter membrane body, and enters the filter chamber. Then, as the air pressure increases, the gas is repeatedly filtered and purified at the filter membrane for many times. However, the exhaust gas will contain solid particles. The filtering effect is not ideal if the exhaust gas is only treated by the filter membrane. Solid impurities will still be mixed in the gas, which is not conducive to discharge. Moreover, after long-term use, the filter membrane will accumulate certain impurities and pollutants. The device only flushes the inner wall of the tower body through the nozzle, the first reflective baffle and the second reflective baffle, but cannot evenly flush the multi-layer filter membrane body above, which easily affects the normal use of the multi-layer filter membrane and is not conducive to effective filtration of the gas. Utility Model Content

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

A partition is fixedly installed below the annular tube second, and a liquid accumulation tank is provided below the partition. A drive rod is movably installed in the liquid accumulation tank, and a filter plate is fixedly provided on the drive rod.

[0008] As a further solution of the present invention, a movable plate is provided on the top of the sealing ring, a spring member is fixedly installed between the top of the movable plate and the inner wall of the tower body, a number of the spring members are provided on the movable plate, a motor is installed on the bottom end of the tower body through fasteners, and a connecting pipe is fixedly installed on the top of the liquid storage tank.

[0009] As a further solution of the present invention, a water pipe 1 is provided on the annular tube 2, and the two ends of the water pipe 1 are respectively fixedly connected to the annular tube 2 and the connecting tube, and pass through the side wall of the tower body. The motor is fixedly connected to the bottom end of the driving rod through the output shaft, and the end of the driving rod away from the motor is connected to the inner wall of the partition through a rotating shaft, and a water pipe is provided at the bottom end of the liquid storage tank.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. First, the exhaust gas is introduced into the tower body through the air inlet pipe, and the treatment liquid is introduced into the liquid trough to make the exhaust gas contact with the liquid. The motor is started, and the motor drives the drive rod to rotate through the output shaft. The drive rod drives the filter plate to rotate, accelerating the liquid flow, so that the exhaust gas is fully in contact with the treatment liquid. The filter plate contains activated carbon filter material, which is used to adsorb solid particles in the exhaust gas. After preliminary filtration, the exhaust gas rises through the air outlet and contacts filter membrane one, filter membrane two and filter membrane three in turn, thereby performing multi-layer filtration.

The exhaust pump can be started to draw the gas at the movable plate into the liquid trough, and the gas is filtered again, which is conducive to enhancing the gas filtration effect.

[0014] 2. By starting the water pump on the water pipe, the used treatment liquid can be extracted and the waste liquid can be sent into the liquid storage tank. After the filter element further filters the waste liquid, the liquid can be sent into the annular pipe 1 and the annular pipe 2 respectively. The spray dropper is installed in an inclined shape on the annular pipe 1, and a number of spray droppers are installed on the annular pipe 1 and the annular pipe 2. The inner wall of the tower body is sprayed and washed through the several spray droppers, and the multi-layer filter membrane can be evenly washed at the same time, which is beneficial to enhance the filtration performance of the filter membrane, strengthen the recycling of the liquid, and reduce the waste of resources.

A filter element (203) is fixedly installed inside the liquid storage tank (2).

[0025] When in use, first, exhaust gas is introduced into the interior of the tower body (1) through the air inlet pipe (201), and a treatment liquid is introduced into the liquid storage tank (101) so that the exhaust gas contacts the liquid. The motor (4) is started, and the motor (4) drives the driving rod (803) to rotate through the output shaft. The driving rod (803) drives the filter plate (802) to rotate, accelerating the flow of the liquid so that the exhaust gas contacts the treatment liquid fully. The filter plate (802) contains activated carbon filter material for adsorbing solid particles in the exhaust gas. After preliminary filtration, the exhaust gas passes through the exhaust outlet.
