Description

Cyclone dust removal membrane type separation device for treating tail gas of fertilizer granulation high tower

Technical Field

The utility model belongs to the technical field of the technique of compound fertilizer manufacturing machinery and specifically relates to a cyclone film type separator that is used for fertilizer granulation high tower tail gas to handle.

Background

The high tower melt granulation technology in China develops rapidly, and fertilizers bloom all the time in a high tower. According to incomplete statistics, the number of towers which are put into production in China by 2018 is over 200, and the number of towers is more than ten. In the actual production process, the tail gas of the high tower is directly emptied at first, and dust is scattered around the tower top with the height of hundreds of meters.

At present, high tower tail gas is treated by adopting an empty tower spraying washing absorption mode, but in actual operation, because the high tower tail gas contains more coarse particles, a spray head for spraying is easy to block, simultaneously, the problems that liquid-gas ratio is large, a dust absorption collection bag is easy to dewing and stick with a bag, the top of a high tower emits white smoke and the like can be caused, the operation environment of workers is severe, and the roof of a nearby resident is often an expanse of white snow. Therefore, a separation device capable of performing gas-solid separation on the high tower tail gas is needed to reduce the pollution of the high tower tail gas to the environment near the fertilizer high tower.

SUMMERY OF THE UTILITY MODEL

The to-be-solved problem of the utility model is to the above-mentioned not enough that exists among the prior art and provide a carry out the cyclone membrane type separator that is used for fertilizer granulation high tower tail gas to handle of gas-solid separation to high tower tail gas.

The above utility model discloses an above-mentioned utility model purpose can realize through following technical scheme:

the utility model provides a whirlwind dust removal membrane type separator for fertilizer granulation high tower tail gas is handled which characterized in that: including circulating water tank, washing circulating pump and along cyclone, scrubbing tower and the polyimide membrane type separator that tail gas flow direction connects in order, the scrubbing tower includes delivery port and water inlet, polyimide membrane type separator includes the leakage fluid dram, delivery port and leakage fluid dram all communicate in circulating water tank, there is the washing circulating pump in order to be used for carrying the liquid in the circulating water tank to the water inlet through the pipe connection between circulating water tank and the water inlet.

The utility model discloses further set up to: the cyclone separator further comprises a coarse particle collector arranged at the bottom of the cyclone separator, and coarse particles separated by the cyclone separator are output into the coarse particle collector through an ash discharge port of the cyclone separator.

The utility model discloses further set up to: the polyimide membrane separator is composed of a stainless steel material.

To sum up, the utility model discloses a beneficial technological effect does: the cyclone separator is used for carrying out preliminary gas-solid separation on the high tower tail gas, then the circulating washing unit is formed by the circulating water tank, the washing circulating pump and the washing tower so as to wash the separated waste gas, and finally the polyimide membrane type separator is used for carrying out gas separation on the washed water vapor.

In the figure, 1, a cyclone separator; 2. a washing tower; 3. a polyimide membrane separator; 11. a first air inlet; 12. a first air outlet; 13. a coarse particle collector; 21. a second air inlet; 22. a second air outlet; 23. a circulating water tank; 24. a washing circulating pump; 25. a water inlet; 26. a water outlet; 31. a third air inlet; 32. a third air outlet; 33. a liquid discharge port; 34. and a liquid discharge pipe.

Detailed Description

In order to make the utility model realize that technical means, creation characteristics, achievement purpose and effect are clearer and easily understand, it is right to combine below the figure and the detailed implementation mode the utility model discloses do further explanation:

referring to fig. 1, for the utility model discloses a cyclone membrane type separator for fertilizer granulation high tower tail gas is handled, including circulating water tank 23, washing circulating pump 24 and along cyclone 1, scrubbing tower 2 and the polyimide membrane type separator 3 that tail gas flow direction connects in order. The first outlet port 12 is connected to the second inlet port 21, and the second outlet port 22 is connected to the third inlet port 31. Wherein, the structural component of the polyimide membrane type separator 3 is made of stainless steel and needs to be cleaned once every half year.

In addition, a coarse particle collector 13 is arranged at the bottom of the cyclone separator 1, and coarse particles separated by the cyclone separator 1 are output into the coarse particle collector 13 through an ash discharge port of the cyclone separator.

The separating apparatus further comprises a circulation water tank 23, a washing circulation pump 24. A drain pipe 34 is arranged at the drain port 33, the drain pipe 34 is connected with the circulating water tank 23, and the water outlet 26 is communicated with the circulating water tank 23 through a pipeline. The washing circulation pump 24 pumps the washing water in the circulation tank 23 through a pipe and delivers the washing water to the water inlet 25. When the washing water in the circulating water tank 23 reaches the mass concentration of 10%, the washing water is discharged and used as supplementary water for a compound fertilizer roller production system.

The implementation principle of the embodiment is as follows: high tower tail gas enters the cyclone separator 1 through the first gas inlet 11, under the action of the cyclone separator, coarse particles enter the coarse particle collector 13 through the ash discharge port, and waste gas after gas-solid separation enters the washing tower 2 through the first gas outlet 12.

Then the washing circulating pump 24 pumps water in the circulating water tank 23, the washing water is sprayed downwards through the water inlet 25 and washes waste gas entering from the second gas inlet 21; the washed water vapor rises to the second air outlet 22 and enters the third air inlet 31, and the washing water flows back to the circulating water tank 23 through the water outlet 26.

Finally, the washed water vapor is separated by the polyimide membrane separator 3, the separated air is discharged from the third air outlet 32, the separated liquid is accumulated at the bottom of the polyimide membrane separator 3, and the accumulated liquid enters the circulating water tank 23 through the liquid discharge port 33 and the liquid discharge pipe 34.

Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
