GX-type tubular graphite falling film absorber
The absorption and heat exchange element of the tubular graphite falling film absorber is an impermeable graphite tube. Compared with the graphite evaporator , the equipment has excellent film forming conditions and high absorption efficiency (generally a single tube produces 0.8-1.2 tons 31% per day) Hydrochloric acid), good product purity, low outlet temperature, stable operation and convenient control.
This equipment is mainly used to absorb HCI gas to produce hydrochloric acid. It can also be used to absorb other gases (SO2, NH3, HF, P2O5, H2S).
This equipment is divided into type I and type II. Type I lower head is impregnated graphite, type II lower head is steel rubber.
Allowable pressure MPa
Design temperature ℃
Executive standard: HG / T3188-2000
Uses: This equipment does not pollute the product. It is mainly used to absorb HCI gas to produce hydrochloric acid. It can also be used for membrane absorption of other gases (SO2, NH3, P2O5, H2S, etc)
1.High absorption efficiency
2.Lower pressure drop in the absorption system
3. The temperature of the produced acid is low, generally 3 ~ 15 ℃ higher than the cooling water, so there is no need for post-cooling, which simplifies the production process.
4. High heat transfer efficiency, equipment corrosion resistance, long service life
