When the downstream device needs high-pressure high-concentration hydrogen peroxide, the upstream device delivers the extrusion gas into the accommodating space 1200 through the second interface 1121, the extrusion gas is a high-pressure gas, and the extrusion gas enters the accommodating space 1200 and then extrudes the high-concentration hydrogen peroxide therein, so that the high-concentration hydrogen peroxide in the accommodating space 1200 is discharged through the first interface 113 in a high-pressure manner and is supplied to the downstream device.

Wherein, the arrangement of the partition 130 provides stable support for the inner tube layer 120, and the overflowing hole 131 on the partition 130 is arranged for realizing communication between the upper layer and the lower layer of the partition 130.

Wherein the tangent plane is a virtual plane.

That is, an extension line of the axis of the first swirl hole 1210 is coplanar and intersects with the axis of the inner cylindrical layer 120, and the axis of the second swirl hole 1211 is coplanar with the axis of the inner cylindrical layer 120. Therefore, the stabilizer entering the accommodating space 1200 through the first swirl holes 1210 is directly injected into the high-concentration hydrogen peroxide, and the stabilizer entering the accommodating space 1200 through the second swirl holes 1211 generates a swirl effect. And then the stabilizer is injected into the accommodating space 1200 in two ways to stir the high-concentration hydrogen peroxide, so that the stabilizer and the high-concentration hydrogen peroxide are sufficiently mixed, and the mixing effect is improved.

It can be understood that there are a plurality of the first swirl holes 1210 and the second swirl holes 1211, and the plurality of first swirl holes 1210 and the plurality of second swirl holes 1211 are distributed on the sidewall of the inner cylinder layer 120.

Further, the axis of each first swirling hole 1210 intersects with the outer side surface of the inner cylinder layer 120 at a first intersection point, and the angle formed by the axis of the first swirling hole 1210 and a tangent plane passing through the first intersection point is 90 °.

The first swirl holes 1210 are matched with the second swirl holes 1211, so that the stabilizer entering the accommodating space 1200 through the first swirl holes 1210 and the second swirl holes 1211 generates a better swirl effect.

In some embodiments, the axis of the second swirl hole 1211 makes an angle of 60 ° to 85 ° with a tangent plane passing through the second intersection point.

In other embodiments, the angle between the axis of the second swirl hole 1211 and the tangent plane passing through the second intersection point may be one of 65 °, 64 °, 68 °, 70 °, 73 °, 74.5 °, 77 °, 80 °, 82.5 ° and 84.5 °, and it should be understood that the above description is only illustrative and should not be taken as limiting the scope of the present application.

Further, the cross section of the inner cylinder layer 120 in the radial direction is a circular ring, the first swirl holes 1210 are located at least one quadrant point of the circular ring, and the second swirl holes 1211 are distributed on both sides of the first swirl holes 1210 to improve the mixing effect.

It will be understood that a notional point is a quadrant of an arc, that is, a circle has four notional points which divide the circle into four equal segments of an arc.

In some embodiments, the first swirl holes 1210 are disposed at four quadrant points of the circular ring, and the second swirl holes 1211 are disposed on four segments of the circular arc.

Further, the second swirl holes 1211 positioned at both sides of the first swirl hole 1210 are symmetrical with respect to the axis of the first swirl hole 1210, that is, the axial directions of the second swirl holes 1211 positioned at both sides of the first swirl hole 1210 form an angle with each other.

In other embodiments, the first swirl holes 1210 and the second swirl holes 1211 are alternately distributed along the axial direction of the inner cylindrical layer 120, so that the orientations of two adjacent swirl holes 121 along the axial direction of the inner cylindrical layer 120 are different, thereby improving the mixing effect.

In other embodiments, the first swirl holes 1210 and the second swirl holes 1211 are alternately distributed along the circumferential direction of the inner cylindrical layer 120, so that the orientations of two adjacent swirl holes 121 along the circumferential direction of the inner cylindrical layer 120 are different, thereby improving the mixing effect.

Of course, the first swirl holes 1210 and the second swirl holes 1211 may be alternately distributed along the axial direction and the circumferential direction of the inner cylindrical layer 120, so that the orientations of the two adjacent swirl holes 121 are different, and the mixing effect is further improved.

The end cover 111 is connected with the upper cylinder section 110a through a flange structure, and a sealing ring is arranged at the joint of the end cover 111 and the upper cylinder section 110a to realize sealing fit. In some embodiments, a welded connection may be possible.

Further, the inclined nozzle 1120b is distributed along the ridge of the conical surface, that is, the end of the end cover 111 far away from the gas-liquid nozzle 112 has a structure of multiple circles of inclined nozzles 1120b along the axial direction of the end cover 111, so that the distribution of the stabilizer entering the flow passage gap 1100 is more uniform.

It should be noted that hydrogen peroxide (H2O2) is widely used as an oxidant in textile, paper, electronics, chemical synthesis, etc. industries, and when used with strong oxidants, it has reducibility.

Because of the influence of temperature, pressure, pH value, metal ions, packaging containers and the like, the general hydrogen peroxide has poor stability, can be slowly and automatically decomposed in the production process and the storage, transportation and practical application process, and meanwhile, the specific application backgrounds can deliberately increase the hydrogen peroxide activity or change the hydrogen peroxide property, if the conditions of high temperature, alkali, metal ions, organic matters and the like are polluted, the hydrogen peroxide can be violently decomposed out of control, oxygen and a large amount of heat energy are released, so that economic loss and even accidents are caused. Therefore, the principle of the application is that the decomposition rate of the hydrogen peroxide can be slowed down by adding the stabilizing agent at the initial stage of the decomposition of the hydrogen peroxide, and the safety of the storage tank and the conveying system thereof is ensured.

Wherein high concentrations of hydrogen peroxide generally refer to concentrations of 90%, 95%, or 98% hydrogen peroxide.
