SO3The absorption of gas.Dry, absorption process is strong exothermal reaction, needs the hot concentrated sulfuric acid drop for exporting drying tower, absorption tower
The concentrated sulfuric acid is squeezed into dry, absorption tower top by low temperature by circulating pump again, by the spray and SO of acid trap2Or SO3Gas connects
It touches, temperature increases；High-temperature sulfuric acid goes out acid tube by bottom of tower and enters acid tank.The cooling temperature range of the concentrated sulfuric acid：Sulfuric acid tower exit temperature
It it is 120-60 °, tower acid temperature is 80-45 ° on sulfuric acid.
Generally use anodic protection stainless steel shell-and-tube concentrated sulfuric acid cooler, plate heat exchanger, shell-and-tube sulfuric acid are cold at present
But device device cools down hot sulfuric acid, and cooling medium is industrial circulating water or soft water, about 20-50 ° of initial temperature, by with hot sulphur
After the heat exchange of acid, water temperature is promoted.It is followed after the reduction water temperature that cooling water after acid cooler passes through common glass fibre reinforced plastics cooling tower
Ring utilizes.
It since cooling water has the evaporation loss of 5%-10%, needs to be continuously replenished, the loss of water is serious.And process pipelines
It is long.Once acid cooler leakage occurs, sulfuric acid will enter circulation, very harmful.All there is floor space in current method
Greatly, pipeline is long, operating personnel are required with the apparent disadvantages such as high, cooling water low temperature heat energy can not utilize, water consumption is big.And for
The arid area of water shortage, water resource are of great rarity, and seriously restrict the operation of sulfuric acid apparatus.

Top；The vacuum heat-pipe is located in shell and concentrated sulfuric acid circulating slot；The lower portion of vacuum heat-pipe is in concentrated sulfuric acid circulating slot
It is interior；The bottom of vacuum heat-pipe is located at the liquid level of concentrated sulfuric acid circulating slot hereinafter, and there are gaps with the slot bottom of concentrated sulfuric acid circulating slot；Very
The upper portion of empty heat pipe is provided with heat exchange fin in shell；The lower part of the shell is provided with air inlet, the top of shell
Portion is provided with air outlet；The enclosure is provided with fan above vacuum heat-pipe；The fan is by being arranged in shell
The motor at top drives.
Further, the concentrated sulfuric acid circulating slot uses anodic protection with concentrated sulfuric acid contact portion.
Further, there are being multiple air inlets in the lower part of the shell along its circumferential spaced set.
Further, n row's m row air outlets are provided at the top of the shell；N > 1；M > 1.
Further, the groove body of the concentrated sulfuric acid circulating slot is horizontal or vertical tank.
The beneficial effects of the utility model：
1）The utility model eliminates sulfuric acid cooler and corresponding pipeline, reduces the risk of sulfuric acid leakage pollution.
2）The utility model eliminates corresponding cycle cooler water system, reduces a large amount of investment and operating cost.
3）The utility model is particularly with water shortage arid area, using air cooling way, by the thorough puzzlement for solving cooling water.
