Description
Technical field
The utility model belongs to oxygen generating plant technical field, relates to oxygen adsorption tower, especially relates to a kind of admission gear of adsorption tower.
Background technology
Oxygenerator be take pressure-variable adsorption (PSA) technology as basis, from air, extract the novel device of oxygen, it utilizes molecular sieve physical absorption and desorption technique in oxygenerator, to load molecular sieve, can be by nitrogen adsorption in air when pressurization, remaining unabsorbed oxygen is collected, and becomes highly purified oxygen after purified treatment.Specific works process is compressed air after air purification drying machine purifies, and by transfer valve, enters adsorption tower.In adsorption tower, nitrogen is by molecular sieve adsorption, and oxygen enters oxygen storage tank after adsorption tower top is built up, then through eliminating the unusual smell, dust removal filter and sterilizing filter filter and obtain qualified medical oxygen.Adsorption tower of the prior art, due to gas in adsorption tower from the bottom to top through sorbing material, the gas after purified treatment is discharged from tower top, makes the size of oxygen adsorption tower have relatively high expectations.
For example, Chinese patent literature discloses a kind of admission gear for adsorption tower [application number: 201220368074.7], comprise cylindrical shell, the bottom of described cylindrical shell is provided with air inlet, in described air inlet, be provided with the airtight adapter of air inlet, the centre of the described airtight adapter of air inlet is provided with sleeve, and the head of described air inlet is provided with inlet flange.Admission gear for adsorption tower is simple in structure, easy to use.
Although such scheme can provide air inlet, it is reasonable not that such scheme still exists design, and air inlet effect is undesirable, cannot reach people's demand, cannot be applicable to the non-oxygen tower filtering from the bottom to top of gas.
Summary of the invention
The purpose of this utility model is for the problems referred to above, provides a kind of reasonable in design, simple in structure, the admission gear of the oxygen adsorption tower that air inlet is satisfactory for result.
For achieving the above object, the utility model has adopted following technical proposal: the admission gear of this oxygen adsorption tower, comprise the lower cover that is fixed on tower body bottom, center at lower cover is provided with air inlet pipe, it is characterized in that, in described tower body, be fixed with the distributor that is positioned at lower cover top, form the large conical cloth air cavity in little upper end, lower end between described distributor and lower cover, described conical cloth air cavity has and is gas outlet circular and straight up.
Further, owing to being provided with distributor, thereby make the gas of output enough even, the air pressure that can make gas by conical cloth air cavity further strengthens or air pressure is remained unchanged.Can certainly use the cloth air cavity of other shapes.
In the admission gear of above-mentioned oxygen adsorption tower, described air inlet pipe is provided with pre-distributor.
Further, by pre-distributor, the distribution of energy air-flow is more even, stable.
In the admission gear of above-mentioned oxygen adsorption tower, between described distributor and lower cover, be provided with some at the equally distributed support plate of circumferencial direction.
Further, some at the equally distributed support plate of circumferencial direction owing to being provided with, make structure more firm, can adapt to different air inlet air pressure.
In the admission gear of above-mentioned oxygen adsorption tower, described lower cover is large coniform in little upper end, lower end, described distributor is the large coniform and distributor in little upper end, lower end and has the vertex of a cone that tapering is greater than periphery position, and the described vertex of a cone is positioned on the axial line extended line of air inlet pipe.
Further, because being the large coniform and distributor in little upper end, lower end, distributor there is the vertex of a cone that tapering is greater than periphery position, thereby air-flow can be shunted by the vertex of a cone, because the vertex of a cone is positioned on the axial line extended line of air inlet pipe, thereby make the shunting effect of gas better.
In the admission gear of above-mentioned oxygen adsorption tower, between described conical cloth air cavity and gas outlet, there is arc gas transmission portion.Owing to being provided with arc gas transmission portion, thereby make gas transmission more smooth.
In the admission gear of above-mentioned oxygen adsorption tower, the outside of described lower cover is provided with some reinforcements.Reinforcement can strengthen the structural strength of lower cover.
Compared with prior art, the advantage of the admission gear of this oxygen adsorption tower is: 1, reasonable in design, simple in structure, air inlet is satisfactory for result.2, divide gas effective, the air flow energy of formation effectively improves oxygen making amount.3, structural strength is high, can adapt to different air inlet air pressure, long service life.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model provides.
In figure, tower body 1, lower cover 2, air inlet pipe 3, distributor 4, conical cloth air cavity 5, gas outlet 51, pre-distributor 6, support plate 7, arc gas transmission portion 8, the vertex of a cone 41, reinforcement 9.
The specific embodiment
As shown in Figure 1, the admission gear of this oxygen adsorption tower, comprise the lower cover 2 that is fixed on tower body 1 bottom, at the center of lower cover 2, be provided with air inlet pipe 3, in tower body 1, be fixed with the distributor 4 that is positioned at lower cover 2 tops, between distributor 4 and lower cover 2, form the large conical cloth air cavity 5 in little upper end, lower end, conical cloth air cavity 5 has and is circular and gas outlet straight up 51.
