Description

The chemical oxygenerator of adjustable catalyst converter

The utility model relates to a kind of chemical oxygen generation device.

Existing chemical oxygenerator all adopts oxygen producing agent and catalyst fines to add preparation oxygen in back in the entry jointly mostly.Though this method is fairly simple, because catalyst fines is not easy to reclaim, uses up at every turn and can only throw away, cause very big waste, and easy pollution clothes and environment.Chinese patent CN2387920Y for example, just there is above-mentioned shortcoming, and because the liquid level of oxygen generating bin and filtration humidifying bin is bigger to the space of loam cake, in the starting stage of producing oxygen, can not be drawn onto pure oxygen in the Oxygen tube exit, but the gas mixture of air and pure oxygen just becomes pure oxygen gradually after after a while.After the oxygen producing agent total overall reaction was intact, because oxygen generator inside has not had pressure, this part pure oxygen also just can't be discharged.These unserviceable oxygen have accounted for 10～15% of each oxygen absorbed.

The purpose of this utility model provides a kind of chemical oxygenerator, and it not only can realize the permanent use of catalyzer, and can regulate according to the demand of producing oxygen, can also reduce unnecessary space in the chemical oxygenerator, and the oxygen of preparing can be fully utilized.

The purpose of this utility model is achieved by the following scheme: the chemical oxygenerator of this adjustable catalyst converter, form by staving (6), loam cake (5), adjustable catalyst converter (8), gas washing chamber's liner (1), reaction chamber liner (3) and porous filtering layer (11) etc., staving (6), be divided into gas washing chamber (13) and reaction chamber (7) two portions, communicate by airway (2); Adjustable catalyst converter (8) in the wall and the bottom of catalyst converter framework (84), is equipped with catalysis side net (85) and catalysis spacer screen (86) that the tabular or network-like porous material of embedded catalyst surrounds, the structure of top for opening wide, and be placed on reaction chamber (7) bottom; By locating slot (83) catalysis mobile network (81) is moved and the location on catalyst converter framework (84) top freely, catalysis mobile network (81) is to form link as hinge by the multi-disc catalysis net with steady brace (82), and, changed contact area with oxygen producing agent by closed and be opened into W shape; Gas washing chamber's liner (1) and reaction chamber liner (3) tighten with loam cake (5) respectively.

The making material of adjustable catalyst converter (8), catalyst converter framework (84) is a plastic cement, catalysis net is the tabular porous material that is embedded with catalyzer, network-like porous material, any in surface applied, the plate material that deposits catalyzer, filamentary material, the Web materials, catalyzer is Manganse Dioxide, cobalt oxide, silver or their mixture.

Porous filtering layer (11) is a placing porous foam layer in the middle of gas washing chamber's liner (1) and oxygen outlet (10), and porous plastics has granules of catalyst in the hole.

The utility model is described in more detail below in conjunction with accompanying drawing and specific embodiments.

Fig. 2 is the structural representation of the chemical oxygenerator of the adjustable catalyst converter of the utility model;

Fig. 3 is the front view of adjustable catalyst converter;

Fig. 4 is two synoptic diagram that the catalysis mobile network combines.

Among the figure: (1) gas washing chamber liner, (2) airway, (3) reaction chamber liner, (4) locking buckle, (5) loam cake, (6) staving, (7) reaction chamber, (8) adjustable catalyst converter, (9) seal gasket, (10) oxygen outlet, (11) porous filtering layer, (12) gauging line, (13) gas washing chamber, (14) fining air bubbles plate, (81) catalysis mobile network, (82) steady brace, (83) locating slot, (84) catalyst converter framework, (85) catalysis side net, (86) catalysis spacer screen.

In Fig. 1, gas washing chamber's liner (1) and reaction chamber liner (3) become an integral body after tightening with loam cake (5).Because liner inside is airtight, so after loam cake (5) and staving (6) covered tightly, liner had been filled unnecessary space on the spot, when beginning to prepare oxygen, has obtained pure oxygen soon at oxygen outlet (10).

Because the utility model adopted adjustable catalyst converter, when preparation oxygen, undesirable black liquor no longer appears in reaction chamber (7), thus staving (6) make with transparent plastics so that observe the situation of product oxygen.Staving (6) and loam cake (5) lock buckle (4) chucking, more difficult gas leakage with 4.Fining air bubbles plate (14) adopts the larger area porous ceramics piece, can allow oxygen bubble more tiny on the one hand, and the pressure of reaction chamber is reduced.

The utility model locates to have placed porous filtering layer (11) at gas washing chamber's liner (1) and oxygen outlet (10), its objective is and eliminates the stimulation of hydrogen peroxide steam to respiratory tract comparatively completely.Present widely used oxygen producing agent mostly is solid peroxide, and the utility model uses is the solid SPC-D.In producing the oxygen process, SPC-D is broken down into yellow soda ash and hydrogen peroxide earlier in water, and hydrogen peroxide is become the oxygen G﹠W by catalyst decomposes again.In newly-generated oxygen, exist hydrogen peroxide steam, also can contain the hydrogen peroxide steam of trace through the oxygen behind the gas washing.Too much suction hydrogen peroxide steam can damage respiratory mucosa.Porous filtering layer (11) is made of sponge plastics, is filled with the activated carbon particle of adsorptive catalyst powder in the hole of sponge plastics, or carries silver-colored activated carbon particle.When through the oxygen behind the gas washing during by the porous filtering layer, the hydrogen peroxide steam of trace will be by catalyst decomposes, thereby has eliminated harm.

Fig. 2 shows the utility model with the spatial array configuration.

Fig. 3 is an adjustable catalyst converter of the present utility model.This catalyst converter is to be injection molded into as the catalyst converter framework (84) among the figure with plastic cement, at catalyst converter framework wall and bottom catalysis side net (85) and catalysis spacer screen (86) is housed.Both sides on the top of catalyst converter framework respectively have a horizontal groove, and some locating slots (83) are arranged in the lower edge of groove, and the effect of locating slot is to fix mobile catalysis net (81) by blocking steady brace (82).Be semicircle between locating slot and the locating slot, can when needs slide mobile catalysis net, reduce resistance like this.Multi-disc move catalysis net by steady brace as the link of the hinge (see figure 4) of getting up, can draw back a plurality of W shapes of picture, also can closure get up, thereby changed contact area with oxygen producing agent.

In the practical application of chemical oxygenerator, generally use the solid oxygen producing agent, this narrated in front, and the product oxygen speed of solid oxygen producing agent is to be directly proportional with the real contact area of input amount, water temperature and catalyzer.Oxygen producing agent all once drops into when each the use, and the solid oxygen producing agent of input sinks to the bottom, contact with the catalysis spacer screen and decomposes product oxygen, and catalysis side net catalytic decomposition is dissolved in the hydrogen peroxide in the water.Because the purposes during each the use is different sometimes, the product oxygen speed that needs during first aid is more faster than the product oxygen speed of health care oxygen uptake, the catalysis speed of depending the catalysis spacer screen alone is just not much of that, at this moment before throwing in oxygen producing agent, product oxygen speed is as required opened mobile catalysis net, until all opening.The solid oxygen producing agent is thrown in the V-type space that per two mobile catalysis nets form, and this has just realized the increase and decrease of catalysis area.Therefore, the utility model has just solved different this problem of product oxygen speed of controlling well.
