Abstract
The utility model relates to an ammonia recycling device, which belongs to the technical field of chemical equipment, and comprises an absorption tower, an ammonia circulation tank, an ejector pump, acirculating pump and the like, wherein the ammonia circulation tank is mounted on one side of the absorption tower, an ammonia water discharge pipe is mounted at the bottom of the ammonia circulationtank, the circulating pump is mounted on one side of the bottom of the ammonia circulation tank, and the ejector pump is mounted above the ammonia circulation tank and connected with an ammonia inletpipe. The device has the benefits that the first spraying and the recycling of ammonia to be recycled is performed through the circulating pump, the ejector pump and a circulation pipe, and then thedual spraying of the ammonia is performed through the low-density ammonia water ejected from an ammonia water pipe and the purified water ejected from a purified water pipe, so that the ammonia is dissolved and enters the ammonia circulation tank through an ammonia water collection pipe for the dual recycling. Therefore, the recycling rate is improved from original 30 percent to 90 percent, and the problem of low absorption efficiency and slow speed in the prior recycling device is solved. Furthermore, the ammonia recycling device has the advantages of simple structure, low manufacturing costand convenient operation, and is particularly suitable for recycling the ammonia in the chemical industry.
Description
Technical field:
The utility model relates to a kind of ammonia retracting device, belongs to technical field of chemical.
Background technology:
Chemical industry is in the production process of using liquefied ammonia, because the effumability of ammonia, a large amount of gaseous ammonias is discharged in the air by the equipment exhausting pipeline, has both caused serious environmental to pollute, and the strong and stimulating smell of ammonia causes discomfort to the direct labor again simultaneously.For addressing this problem, all be to adopt the absorption pattern of single cycle water spray to reclaim usually, be about to ammonia to be recycled and introduce the bottom of spray column after distributor is capable from bottom to top, clear water then enters from the spray column top, through distributor to filler, flow to tower from cat head at the bottom of, obtain weak aqua ammonia at the bottom of the tower.But there is following defective in this absorption pattern:
1. absorption efficiency is low, can only reach the assimilation effect of total amount 30%;
2. the absorption tower is limited by equipment blow-down pipe distance and potential difference, very easily forms gas and stops up, and the normal use of emptying device is impacted.
3. water consumption is big, and the weak aqua ammonia content that obtains is low, must absorb through secondary just can obtain high-load ammoniacal liquor.
4. nearly 70% ammonia that can't absorb enters atmosphere, and environmental pollution is serious.
Summary of the invention:
The purpose of this utility model is: a kind of ammonia of the discharging of synchronous collection in process of production is provided, conventional absorption efficiency can be promoted to more than 90%, and low to solve existing retracting device organic efficiency, the ammonia retracting device of the problem that infiltration rate is slow.
The utility model is to realize above-mentioned purpose by following technical solution:
A kind of ammonia retracting device, it is by the absorption tower, the ammonia circulating tank, jet pump, circulating pump constitutes, and it is characterized in that: absorption tower one side is equipped with the ammonia circulating tank, and the ammoniacal liquor discharge nozzle is equipped with in the bottom of ammonia circulating tank, bottom one side of ammonia circulating tank is equipped with circulating pump, and the top of ammonia circulating tank is equipped with jet pump and is connected with the ammonia air inlet pipe; Pure water pipe, ammonia water pipe, ammonia pipe and ammoniacal liquor collecting pipe are housed on the described absorption tower from top to bottom successively.Described circulating pump connects with the ammonia circulating tank by circulation pipe with jet pump and is connected; Described ammonia water pipe is connected with circulation pipe.Described ammonia pipe is connected with the ammonia circulating tank with the ammoniacal liquor collecting pipe.
The utility model beneficial effect compared with prior art is: the utility model is at first through circulating pump with ammonia to be recycled, jet pump, circulation pipe carries out the spray recovery first time, making it a part is dissolved in the ammonia circulating tank, not dissolving part enters in the absorption tower by the ammonia pipe, by by the low concentration ammoniacal liquor of ammonia water pipe ejection and the dual spray of water purification of pure water pipe ejection, makes its dissolving once more, and enter in the ammonia circulating tank by the ammoniacal liquor collecting pipe, ammonia is carried out dual recovery; Make the rate of recovery bring up to 90%, avoided low, the slow-footed problem of existing retracting device absorption efficiency by original 30%.And the utility model is simple in structure, and cost is low, and is easy to operate, is specially adapted to the recycling of chemical industry to ammonia.
