SU6515A1 - Adaptation to pipelines to remove vapors or gases from them. - Google Patents

Description

The proposed adaptation to pipelines for the removal of vapor from them gases emitted by liquids is intended primarily for those cases where the removal of vapors or gases using an ordinary ventante is made impossible or irrational, such as when diverting from the upper bend of siphons high pressure pipelines, etc.

To solve this problem, it is proposed to apply a plunger in combination with a gas or steam pipeline running from it, adjoining again either to the main line or to a parallel pipe, or to any suction device. At the same time, in order to move along the shunt or front, just to the gas oils of the steam line, a pressure difference must be created by any suction device placed on the main at the mouth of the bypass, for example, a Venturi pipe, an injector, etc. To increase the pressure difference in At the beginning and end of the withdrawal, a diaphragm can be placed on the bypass section of the highway and entered more easily.

rounding, or like a piece, giving added resistance.

Since the presence of a water meter or an oil gauge will also provide ample resistance, according to the invention, it is possible to arrange a shunt with a plunger in its source around the water meter. In this case, the vapor and air will move along the shunt, while the liquid will not move, since the vent valve will prevent this. For ease of repair, at the beginning and end of the shunt, you can put valves and taps. To be able to observe the operation of the shunt, the plunger can be equipped with water-measuring glass and the shunt-water-measuring valve.

The proposed adaptability is represented in the drawing, pa of which FIG. 1, 2, J and 4 depict schematic variations of its implementation forms and FIG. 5.6 and 7 is the same, with the use of water meters or meters.

Pa figs. 1 shows an example of steam and gas through line A using a suction device B, namely the Venturi tube, which branch D is attached to the throat. It comes from the plunger C installed on tee J of the pipeline A. Vantuz C is equipped with water-meter glass and, and branch D- N, N vent valves. Between pipeline A and plunger C, a valve is installed.

FIG. Figure 2 shows a variant of the device, where a head is created by some shaped part 5 supplied on the encircled section: the highway. The bypass will join the cylindrical part of the highway. In this example, under the letter B of course the diaphragm.

Sometimes there are times when accumulations of vapor and gases are desirable to remove from the mainline. This can be done with the aid of the proposed fixture, adjoining the end of the branch to any other pipeline. In this case, the branch is transformed into a transfer pipe. In order for the transfer pipe to move, it is necessary that the pressure at the end of it be lower than the pressure at the beginning. In the receiving pipeline, it is possible to place a suction device at the mouth of the front pipe or temporarily reduce the pressure at the inlet of the transfer pipe with the help of a Venturi pipe and make it smaller than the pressure in the source of the non-ejection pipe. In practice, such transmission can reduce heat loss and eliminate shocks and shocks in the network. Using this method, it is possible to transfer vapors released in the pipeline with hot water to a lower pressure steam pipe located in the same room. If the receiving steam line is under higher pressure, then some suction device should be placed on it.

FIG. 3 shows the implementation of such a transfer from the pipeline shown in FIG. 1. Branch D is attached to the throat of the Venturi B pipe installed on the A line. At the end of the D branch, the F valve is positioned and the N valve is in front of it. The Venturi pipe can be replaced with any suction device, if the pressure in the receiving pipe is lower than the pressure the source of the transfer pipe, the suction device is not necessary. Finally, suction

can be made with any suction device: pump, condenser, etc.

FIG. 1 and 3 there is also an option where on branch D there is a three-way valve W, from which branch D goes to branch D in FIG. 1. With the help of a crane M, the vapors and gases can be directed either to the main line A (Fig. 1) or to the auxiliary pipeline A (Fig. 3).

Node line means not only a cylindrical pipeline, but a wire of fluid in a vessel of any shape.

FIG. Figure 4 shows a variant of the adaptation, consisting in the use of a siphon, in which the rising knee serves as a bell, embracing the descending knee, for example, a drain pipe in the rinsing tanks.

The siphon is made of a vertical pipe, including a venturi pipe embraced by the bell JS at the bottom of the tank. From the inside to the bottom of the bell attached with a few bolts funnel -b. Due to the tides or washers, a gap is formed between the bottom of the bell and the upper funnel f.e6poM. By raising the level of the liquid in the tank, it establishes its flow along arrows a and the flow of vapors or gases along arrows d. The same results can be achieved if a tube is drawn from the top of the bell bottom, D through the bell to the throat of the Venturi tube or any suction device B.

In cases where there are instruments for measuring the flow of hot liquids in the pipelines, the measurement is made difficult by the presence of steam and air, which usually contain impulses in the water meters, disrupting their performance, spoiling the mechanism and altering the accuracy of the readings. It is impossible to remove air and vapors into the atmosphere with the help of a conventional vent, since hot water usually travels under high pressure and, therefore, vapor and gases will not be released into the air from the vent hole, since the float pressed with high pressure the accumulation of air or steam in the vaptuz does not fall

and therefore will not open the outlet.

In order to eliminate these inconveniences, it is possible to take advantage of the fact that each water meter creates more or less significant head losses. To do this, a plunger A is placed before the water meter B (Fig. 5), to which there is a branch J connected at the water meter. Along this circuit, the vapors and gases from the plunger chase after the water meter and again enter the pipeline E.

In the embodiment illustrated in FIG. 6 shows a water meter consisting of a Venturi tube C, a counter D, a plunger, a bypass J, valves of various purposes G and .P, flush valves N and blow-off valves M. At the same time, the plunger can be placed not on the line, but on the bypass, a vapor or gas or air duct can be directed not by the end, but into the throat of the venturi. An example is shown in FIG. i, where meter B is placed on the bypass, which in turn is equipped with valves F. F} c with a flushing valve M. There is a tee in front of the Venturi pipe, valve G and Vantuz A are located next to the gas pipeline /, also attached. to the throat of the tube Vbnturi. A bypass valve DT and a crane in case of repair. Tap F. The Venturi tube is also equipped with flush valves N N. The plunger can be equipped with a waterglass for easy monitoring of its operation.
