Description
Technical field
Environmental technology field is the utility model is related to, more particularly to one kind prevents molecular sieve in the gas such as oxygen processed or nitrogen processed
One kind of efflorescence prevents molecular sieve device.
Background technology
Molecular sieve wettability power is extremely strong, for the purification process of gas, in industrial production the gas of drying process have air,
Hydrogen, oxygen, nitrogen, argon gas etc..
Two major reasons of molecular sieve：
1st, excessive gas shock：Because sieve particle is smaller, if being not provided with gas distribution or gas flow homogenization device, cause gas
A certain fritter molecular sieve is impacted in adfluxion, causes its efflorescence.
2nd, molecular sieve is not compacted：Once molecular sieve is not compacted, with the running of system, the impact of air-flow, it may appear that point
Directly friction or the impact of son sieve, can aggravate the efflorescence of molecular sieve, as a small amount of molecular sieve is discharged with air-flow, molecular sieve drum
Interior space increases, and the impact between molecular sieve can be bigger, and pulverization situation is incremental by geometric progression.
3rd, moisture enters in molecular sieve drum：Because moisture enters, molecular sieve is caused to absorb water, the intensity of molecular sieve after water suction
Drastically decline, in the case of gas shock, easily cause molecular sieve, although substantially air, ducted systems front end all can
Moisture is handled, but is substantially difficult by moisture removal to preferable degree due to cost considerations.
Utility model content
The utility model is in order to solve above mentioned problem existing for prior art, there is provided a kind of dress for preventing molecular sieve
Put, including adsorption tower, Shang Tagai, Xia Tagai, the upper tower lid are fixedly mounted on the upper end of adsorption tower, pass through sealing ring and absorption
Tower is tightly connected, and the lower tower lid is fixedly mounted on the lower end of adsorption tower, is tightly connected by sealing ring and adsorption tower, the suction
Cavity of the attached tower by Shang Tagai with lower tower cap-shaped into a sealing；
Further, multiple cavities are formed by the isolation of air distribution plate in the adsorption tower；
Further, the air distribution plate is respectively equipped with the first air distribution plate, the second air distribution plate, the 3rd air distribution plate, will inhale respectively
Cavity in attached tower is isolated into the first cavity, the second cavity, the 3rd cavity, the 4th cavity；
It is fixed in first cavity to set spring as further scheme of the present utility model, pass through spring and control first
Tensile force between air distribution plate and upper tower lid；
Activated alumina is placed in second cavity, the gas entered in the second cavity is carried out by activated alumina
Moisture solution；
Molecular sieve is placed in 3rd cavity, gas is further processed by molecular sieve, being finally reached will
Ask, gas is flowed out by the 4th cavity and lower tower lid.
As further scheme of the present utility model, the air distribution plate uses disc structure, and bottom is provided with multiple apertures, outside
Surface is tightly connected with adsorption tower.
Effect of the present utility model is：1st, air-flow is ensured by the aperture on the air distribution plate that is set between cavity and cavity
It is evenly distributed, reduces impact of the air-flow to molecular sieve；2nd, molecular sieve compressing is avoided by the spring that is set in the first cavity
Molecular sieve is vibrated during transport or use and produces molecular sieve sinking, to reduce the friction of molecular sieve and impact；3rd, second is passed through
Activated alumina is set in cavity, moisture solution is carried out to the gas by the second cavity, effectively reduces and enters in the 3rd cavity
Gas moisture.
