Abstract
The utility model discloses a fluorine hydride gas recovery device comprising a water washing tower, a circulating pump and a vacuum pump, wherein an outlet of the water washing tower is connected with an inlet of a fluorine hydride absorption tank which is connected with the water washing tower through the circulating pump; and the vacuum pump is connected with a gas outlet of the fluorine absorption tank. The fluorine hydride gas recovery device can make the double recovery of fluorine hydride, thus improving the recovery rate of the fluorine hydride and further reducing the use quantity of washing water; and the power consumption of the vacuum pump is reduced as the packing water washing tower is used and the gas resistance is low.
Description
Technical field
The utility model relates to a kind of chemical industry equipment, especially a kind of hydrogen fluoride gas retrieving arrangement.
Background technology
In Chemical Manufacture, regular meeting produces a large amount of waste gas that contains hydrogen fluoride gas, and a large amount of waste gas that contains hydrogen fluoride gas in air, had both caused the pollution of environment by equipment exhausting, also workman healthy has been caused very big influence.For addressing this problem, factory adopts the single loop water washing tank to absorb usually, but there is following defective in this method:
(1) can not eliminate hydrogen fluoride in the waste gas completely;
(2), need the power of consumption vacuum pump big because of the absorption process resistance is big;
(3) water consumption in the absorption process is big.
The utility model content
The technical problems to be solved in the utility model provides that a kind of hydrogen fluoride absorbed dose is big, and the washing water usage quantity is little, the hydrogen fluoride gas retrieving arrangement that the vacuum pump power consumption is few.
In order to solve the problems of the technologies described above, hydrogen fluoride gas retrieving arrangement of the present utility model comprises water wash column, recycle pump and vacuum pump, and the outlet of described water wash column links to each other with the import of hydrogen fluoride tourie; Described hydrogen fluoride tourie links to each other with water wash column by described recycle pump; Described vacuum pump links to each other with the pneumatic outlet of hydrogen fluoride tourie.
Further, water wash column is two: first water wash column and second water wash column; Described hydrogen fluoride tourie is two: the first hydrogen fluoride tourie and the second hydrogen fluoride tourie; Described recycle pump is two: first recycle pump and second recycle pump; The outlet of first water wash column links to each other with the import of the first hydrogen fluoride tourie, and the first hydrogen fluoride tourie links to each other with first water wash column by recycle pump; The outlet of water wash column second links to each other with the import of the second hydrogen fluoride tourie, and the second hydrogen fluoride tourie links to each other with second water wash column by second recycle pump; The pneumatic outlet of the first hydrogen fluoride tourie also links to each other with the gas feed of second water wash column, and the second hydrogen fluoride tourie pneumatic outlet also links to each other with the gas feed of first water wash column.
Further, described water wash column is the filler water wash column.
Owing to adopted said structure, hydrogen fluoride has been carried out dual recovery, improve the rate of recovery, and then reduced the usage quantity of washing water; Owing to used the filler water wash column,, thereby reduced the power consumption of vacuum pump so air resistance is little.
Description of drawings
Be described in further detail below in conjunction with accompanying drawing and embodiment of the present utility model:
Fig. 1 is a kind of hydrogen fluoride gas retrieving arrangement synoptic diagram.
Embodiment
Hydrogen fluoride gas retrieving arrangement shown in Figure 1, comprise first water wash column 1, second water wash column 2, the first hydrogen fluoride tourie, 3, the second hydrogen fluoride touries, 4, the first recycle pumps 5, second recycle pump 6, link to each other with the import of the first hydrogen fluoride tourie 1 with the outlet of vacuum pump 7, the first water wash columns 1, the first hydrogen fluoride tourie 1 links to each other with first water wash column 1 by first recycle pump 1; The outlet of second water wash column 2 links to each other with the import of the second hydrogen fluoride tourie 2, and the second hydrogen fluoride tourie 2 links to each other with second water wash column 2 by second recycle pump 2; The pneumatic outlet of the first hydrogen fluoride tourie 1 links to each other with second water wash column 2, and vacuum pump links to each other with the pneumatic outlet of the second hydrogen fluoride tourie 2.Water wash column can be the filler water wash column, also other water wash columns that can be easy to associate for other those skilled in the art.During working order, in first water wash column 1 and second water wash column 2, feed and contain hydrofluoric waste gas, in first water wash column 1 and second water wash column 2, feed water simultaneously, in first water wash column 1 and second water wash column 2, finished hydrofluoric preliminary absorption, finish containing of preliminary absorption hydrofluoric water and waste gas be sent to the first hydrogen fluoride tourie 1 and the second hydrogen fluoride tourie 2.In the first hydrogen fluoride tourie 1 and the second hydrogen fluoride tourie 2, feed water, carry out the hydrofluoric secondary that contains in the waste gas in the jar is absorbed.Contain that hydrofluoric water is passed into first water wash column 1 by recycle pump respectively and second water wash column 2 carries out hydrofluoric preliminary absorption to the waste gas of firm feeding once more after finishing secondary and absorbing; The waste gas that still contains low amount of fluorinated hydrogen after finishing secondary and absorbing feeds first water wash column 1 once more and second water wash column 2 absorbs.By such washing of repeatedly round-robin and absorption, can be with the hydrogen fluoride that absorbs completely in the waste gas.
Above embodiment only is the utility model a kind of embodiment wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
