Description
Technical Field
The utility model belongs to the technical field of purification of chemical gas, and particularly relates to a filler washing tower.
Background
The packed column is suitable for the case where the gas handling capacity is large and the liquid amount is small because the fluid resistance is small. The liquid flows from top to bottom along the surface of the packing, and the gas and the liquid flow in a counter-current or co-current manner, depending on the specific reaction. The liquid storage amount in the packed tower is small. The flow pattern within the column is close to plug flow, whether in the gas or liquid phase. If the reaction process is carried out by solid phase production, a packed column is not suitable.
The packed tower has the following problems in application: 1) after the gas phase and the liquid phase are in contact reaction, a large amount of liquid phase substances are carried in the gas, and if corrosive media are used, the discharged gas pipeline is easily corroded. 2) If the mist catcher is arranged at the outlet of the gas pipeline, at present, a silk screen mist catcher and a rotational flow mist catcher are more applied, and both the two mist catchers can generate larger resistance to greatly influence the system. 3) The method of arranging the mist catcher in the gas outlet pipeline has the disadvantages of difficult installation and difficult maintenance. 4) The common packed tower can cause larger resistance to the system and has larger influence on the system. Most of gas purification systems of iron and steel enterprises in China are built, blowers with larger replacement capability cannot be realized, and a novel tower type device which can realize the function of the original packed tower and has the function of mist catching is urgently needed under the condition that the gas purification system is continuously provided with newly increased treatment procedures.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model aims to provide a packing washing tower, which adopts a mode of combining the packing washing tower with a mist catcher, and does not need to separately arrange the mist catcher in a gas phase outlet pipeline for gas-liquid separation.
In order to achieve the purpose, the utility model is realized by the following technical scheme:
a filler washing tower comprises a tower body, wherein a gas outlet is formed in the upper portion of the tower body, a gas inlet is formed in the lower portion of the tower body, a mist catching layer is arranged in the tower body, a liquid phase spraying device is arranged below the mist catching layer, a grid plate for supporting mist catching filler is arranged above the mist catching layer, and a filler pressing plate is fixed above the mist catching filler.
The top of the tower body is provided with a mist-catching layer purging device, and the mist-catching layer purging device is arranged above the gas outlet.
The packing pressing plate is arranged below the gas outlet.
The mist catching filler is a rhombus heavy-ring filler.
The packing press plate is fixedly connected to the tower body through bolts.
Compared with the prior art, the utility model has the beneficial effects that:
the filler washing tower realizes the purpose of realizing gas-liquid separation of the reacted substances while purifying the gas-phase substances by using the filler washing tower, and does not need to separately arrange a mist catcher on a gas-phase outlet pipeline. The concrete advantages are that:
1) the packing tower is convenient to manufacture and install, and the mist catcher does not need to be installed independently after the packing tower is combined with the mist catcher;
2) the packed tower is convenient to overhaul, and the mist-catching layer blowing device is started when the packed tower is overhauled;
3) the investment is saved, and the investment for independently setting the mist catcher is saved;
4) the occupied area is small, and the mist catcher is arranged in the packed tower;
5) the influence on the running resistance of the system is small, the independent rotational flow mist catching device and the screen mist catching equipment can generate larger resistance, and the resistance reduction value caused by mist catching is greatly reduced in the running process of the device.

Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings, but it should be noted that the present invention is not limited to the following embodiments.
Referring to fig. 1, the filler washing tower comprises a tower body 2, wherein a gas outlet 7 is arranged at the upper part of the tower body 2, a gas inlet 1 is arranged at the lower part of the tower body 2, a mist catching layer is arranged in the tower body 2, and a liquid phase spraying device 3 is arranged below the mist catching layer and used for uniformly spraying liquid phase substances to enable the liquid phase substances to be in contact with and react with gas phase substances. The bottom of the tower body 2 is provided with a water seal device which is arranged below the gas inlet 1 to prevent the reaction gas from leaking and is also used as a liquid collecting device for separating the mist catching layer. And a grating plate 4 and a support frame for supporting the mist catching filler 5 are arranged above the mist catching layer and are used for supporting the mist catching filler 5 and installing the mist catching filler 5. A packing pressure plate 6 for preventing the gas phase from blowing down the packing is fixed above the mist catching packing 5, and the packing pressure plate 6 is arranged below the gas outlet 7. The mist catching filler 5 is a rhombus heavy-ring filler which has large specific surface area and small resistance.
The top of the tower body 2 is provided with a mist-catching layer blowing device 8, the mist-catching layer blowing device 8 is arranged above the gas outlet 7, the mist-catching layer blowing device 8 can blow and clean the mist-catching filler 5 by using circulating liquid, and the mist-catching layer blowing device 8 can be introduced with industrial water or steam and other media.
The packing pressing plate 6 is fixedly connected to the tower body 2 through angle steel and bolts, installation is convenient, and the reduction of the packing pressing plate 6 can be furthest influenced by system resistance. The distributor and the filler layer are arranged below the liquid phase spraying device 3.
The operation mode of the packing washing tower is as follows: gas phase substances enter the tower from the gas inlet 1 and contact and react with liquid phase substances sprayed by the liquid phase spraying device 3 from top to bottom after being uniformly distributed, the liquid phase substances are discharged out of the tower from the bottom of the tower, the gas phase substances carrying the liquid phase substances continuously flow upwards to enter the mist catching filler 5, the mist catching filler 5 catches mist to realize a gas-liquid separator, pure gas phase substances flow upwards to enter the next process through the gas outlet 7, liquid phase substances directly flow into the filler at the lower section of the mist catching layer, a flow dividing pipe is not needed to be arranged independently, and the weight of the tower is saved. And meanwhile, when the system resistance is increased and the gas-liquid separation effect is not obvious, the mist-catching layer is blown by the mist-catching layer blowing device 8.
