Description

The present invention relates to injection equipment for compressing air and other gases (hereinafter referred to as air for short), which devices are of the type in which air is carried by a mass of water falling from its own weight in the intake or compressor channel, after which it is released and is compressed in a chamber from which, in a compressed state, it is directed to a storage tank or to an apparatus driven by compressed air. In previously known devices of this kind, the liquid freed from entrained air in the compressor chamber is then not used, in the proposed device the liquid used for compression and continuously circulates from high level to low and back, keeping the same volume and production compressed air. One or more liquid return channels located between the compressor chamber and the high level are used, in conjunction with a centrifugal pump of such capacity and power that it is able to overcome the pressure difference and maintain a constant circulation of the liquid, which thus flows from high level, through the inlet or compressor channel to the compressor chamber and then through the return channels back to the high level. two or several devices of the indicated type, forming a compressor device of two or several stages, in which the compressed air from the compressor chamber of the first device is directed into a closed chamber of the device containing liquid at a high level, etc., if the number of devices According to the proposed device You can have consistently

more than two. In this way, it is possible with a relatively small difference in the levels to achieve a high degree of air compression, as compared with a single-stage apparatus.

FIG. 1 and 2 are schematic side views of two forms of the proposed devices, FIG. 3-side view of the device with two devices connected in series and in FIG. 4 is a modification of the device shown in FIG. 3

In the device shown in FIG. 1 and 2, designation A represents an inlet or compressor pipe, a high-level drive fluid / to a compressor chamber A, provided at or near the top with a tube for directing compressed air to storage tanks or to an apparatus that acts with compressed air, and near the bottom has a tube B for discharging liquid from said chamber. The upper end of the tube A extends into the reservoir / —high level — and has an inlet head B- of a known suitable device.

FIG. 1 BI discharge tube leads to an open reservoir C, positioned so that it forms a lower level of liquid 2, compared to a reservoir / high level; Thus, pipe B corresponds to the upward channel in existing devices. The other pipe C, leading from the open tank C to the high level tank 1, is equipped with a return pump C2 of centrifugal type. This pump has such a capacity and power that pumps the liquid from tank C to a high level 7 at approximately the same speed as the supply of liquid to tank C from chamber B.

In the device shown in FIG. 2, tank C is absent; the tube fii in this case goes without interruption from the compressor chamber B to a high level / and has a height equal to the sum of the lengths of the tubes fii and C1 of the device of FIG. , moreover, the centrifugal pump is connected to the tube B in its lower part.

In the battery device shown in FIG. 3, the compressed air from the compressor chamber B is directed along

tube b into closed chamber D containing liquid at tank level I, which descends into compressor chamber B through compressor pipe L and returns again from chamber B to chamber D, under the action of pump C-, through the pipe. Above the upper end of the compressor tube A is located the inlet head B. Thus, in the device shown in FIG. 3, the air pressure in chamber B will be double against the pressure in chambers B and D if tubes A to A have the same length and the air tube b serves to discharge compressed air from chamber B to storage tanks or apparatus acting with compressed air . Several devices of this kind can be connected in series, subjecting the air to re-compression, according to the number of devices.

The apparatus of the first stage can also have the device shown in FIG. one; the apparatus — the second and subsequent compression stages — must have a continuous return tube, as shown in FIG. 2

In the modified battery device shown in FIG. 4, tube b removes compressed air from chamber B to chamber D, as in FIG. 3, but fluid is passed from chamber B to chamber D through pipe 50, equipped with a centrifugal pump — the required capacitance and capacity, and the liquid from chamber B returns to a high level / through pipe — by air pressure in chamber B. This device needs only one pump, whereas in the device shown in FIG. 3, requires two pumps.

Water usually serves as a liquid, but since no liquid is lost in an improved apparatus, it is possible to use any other liquid, depending on the desired purpose.

SUBJECT OF THE PATENT.

1. A two-stage or multi-stage hydraulic injection device for compressing air and other gases using pumps to continuously maintain the circulation of fluid in it, characterized in that two or more injection devices of the well-known device are connected in series with the help of pipe b (Fig. 3 ) supplying the compressed gas from the compressor chamber B of the first apparatus into the closed chamber D containing the high level / second fluid liquid, and so on for each subsequent apparatus, if there are more than two, with I eat each unit has a singly pump. Apparatus according to claim 1, characterized in that the liquid from the compressor chamber B of the first apparatus (Fig. 4) is sent to the closed chamber D of the second through the channel B equipped with pump C, and the liquid from the compressor chamber fi of the second apparatus is transferred through channel 500 to a high level / of the first under the action of the pressure of compressed gas in the designated chamber 3, and two devices are serviced by one pump. 2. Modification of the two-step
