Abstract
The utility model disclose and provide a kind of reasonable in design, structure for molecular sieve adsorption oxygen simple, effectively can slow down gas velocity and the airflow distribution device that can extend molecular sieve work-ing life.This airflow distribution device being used for molecular sieve adsorption oxygen comprises ventilation cylindrical shell (1) and spiral deceleration splitter (2), and described spiral deceleration splitter (2) is arranged on the inside of described ventilation cylindrical shell (1) and suitable with the inside of described ventilation cylindrical shell (1).The utility model is applicable to medical molecular-sieve oxygen generator Application Areas.
Description
Technical field
The utility model relates to a kind of airflow distribution device for molecular sieve adsorption oxygen.
Background technology
At present, on market, medical molecular-sieve oxygen generator all adopts tank type adsorption tower structure, the intake pressure that its molecular sieve oxygen generation generally adopts is all higher than 5bar, and general tank body when air inlet in tank original pressure be less than 0.5bar, both draught heads are remarkable, and the inlet end of this kind of tank body all adopts vertical barrel type gas distributor, its effective gas distribution limited area, in the tank of High Pressure Difference during gas distribution, the phenomenon that ubiquity not rationally causes the generation of sparger periphery molecular sieve to replace because of distributor designs, thus cause molecular sieve friction and efflorescence, duration of service one is long, just the work-ing life of molecular sieve can be shortened, more can have a strong impact on the oxygen effect of molecular sieve.
Utility model content
Technical problem to be solved in the utility model overcomes the deficiencies in the prior art, provide a kind of reasonable in design, structure for molecular sieve adsorption oxygen simple, effectively can slow down gas velocity and the airflow distribution device that can extend molecular sieve work-ing life.
The technical scheme that the utility model adopts is: the utility model comprises ventilation cylindrical shell and spiral deceleration splitter, and described spiral deceleration splitter is arranged on the inside of described ventilation cylindrical shell and suitable with the inside of described ventilation cylindrical shell.
Described ventilation cylindrical shell presents that end is remained silent, the cylinder of lower ending opening, and the barrel of the upper end of described ventilation cylindrical shell is evenly provided with several ventilating pits, and lower end is provided with the bottom plate horizontally outward extended from port.
The two ends up and down of described spiral deceleration splitter are fixedly installed through hole spreader plate respectively, and the inwall of described through hole spreader plate and described ventilation cylindrical shell is suitable.
Leave space between the upper surface of described spiral deceleration splitter and the upper surface of described ventilation cylindrical shell, described ventilating pit is all arranged on the barrel on the upper surface being in described spiral deceleration splitter.
Gas voltage stabilizing space is left between the lower surface of described spiral deceleration splitter and the lower port of described ventilation cylindrical shell.
The beneficial effects of the utility model are: the utility model is arranged on the ingress of the tank body of oxygen molecular sieve, in the utility model, owing to have employed lower ending opening, upper end is provided with the ventilation cylindrical shell of ventilating pit, and the inside of this ventilation cylindrical shell is provided with spiral deceleration splitter, so this is crossed after spiral deceleration splitter can carry out spiral deceleration to outside high velocity air enter molecular sieve tank interior with allowing gas uniform again, in protection tank body, in adsorbing tower with molecular sieve, sieve particle is no longer subject to the impact of high-voltage high-speed airflow, thus extend the work-ing life of sieve particle, more ensure that sieve particle performance, ensure that its oxygen effect.
Accompanying drawing explanation
Fig. 1 is the new structural representation of this practicality;
Fig. 2 is the working state structure schematic diagram that the utility model combines with molecular-sieve oxygen generator.
Embodiment
As shown in Figure 1, the utility model comprises ventilation cylindrical shell 1 and spiral deceleration splitter 2, described ventilation cylindrical shell 1 is remained silent in upper end, the cylinder of lower ending opening, the barrel of the upper end of described ventilation cylindrical shell 1 is evenly provided with several ventilating pits 11, lower end is provided with the bottom plate 12 horizontally outward extended from port.
The global shape size of described spiral deceleration splitter 2 and the interior barrel chamber of described ventilation cylindrical shell 1 suitable and be arranged on wherein.The two ends up and down of described spiral deceleration splitter 2 respectively fixing horizontal are welded with through hole spreader plate 21, and described through hole spreader plate 21 is suitable with the inwall of described ventilation cylindrical shell 1.
Leave space between the upper surface of described spiral deceleration splitter 2 and the upper surface of described ventilation cylindrical shell 1, described ventilating pit 11 is all arranged on the barrel on the upper surface being in described spiral deceleration splitter 2.
Leave gas voltage stabilizing space between the lower surface of described spiral deceleration splitter 2 and the lower port of described ventilation cylindrical shell 1, this voltage stabilizing space is the pressure stabilizing cavity 13 of extraneous gas.
Principle of work:
As shown in Figure 2, the utility model is arranged on tank mouth 31 place of the adsorption tower 3 of medical molecular-sieve oxygen generator, the upper end that described ventilation cylindrical shell 1 is provided with ventilating pit 11 extends to the inside of described adsorption tower 3 completely, described bottom plate 12 is clamped between the end plate 32 on a flange 4 with centre hole 41 and described tank mouth 31, and then make described ventilation cylindrical shell 1 be fixed on described tank mouth 31 place, described flange 4 external gas source.
Open described external air source, the gas of high pressure enters described pressure stabilizing cavity 13 through described centre hole 41, described gas at described pressure stabilizing cavity 13 after preliminary slow voltage stabilizing, the inside of described spiral deceleration splitter 2 is entered and the flight helicoidal flow along described spiral deceleration splitter 2 inside through described through hole spreader plate 21, in the process, slow down the velocity of flow of described gas further, then, through a part of last part without described flight of described gas of deceleration, the described through hole spreader plate 21 through the upper end surface of described spiral deceleration splitter 2 enters the upper end of described ventilation cylindrical shell 1, another part of described gas then directly enters the upper end of described ventilation cylindrical shell 1 after the last part through described flight, and the gas entering described ventilation cylindrical shell 1 upper end is the inside entering described adsorption tower 3 regularly finally by described ventilating pit 11, and contact with sieve particle 5.
When discharging the gas of described adsorption tower 3 inside, the flowing-path of this gas is contrary with above-mentioned path, but its effect is consistent.
The utility model is applicable to medical molecular-sieve oxygen generator Application Areas.
