CZ278685B6 - Flow-through gas separator from liquids - Google Patents

Abstract

The basis of the flow-through separator is the compensation of pressure differences between a liquid tank (1) and the large underpressure in the vacuum pump (8), to prevent drawing in of the transflowing liquid. To this aim the compensating section (3), beyond the regulated swelling of liquid into the inner space of the separator, is uniformly widened and separated by rows of fire bar surfaces (4). The fire bar surfaces are connected at the top in the suction space (7) of the pump by the jaws of the guide sections (6) for catching the released fluid drops. In the fluid of the separator there is a flow regulator (12) which, by means of a drawbar (10), controls the flow through the suction neck of the pump (11), located at the end of the separator in at its lowest point.<IMAGE>

Description

(57)

The basis of the flow separator is mainly to equalize the pressure differences between the liquid reservoir (1) and the high vacuum in the pump suction (8) so that the liquid flowing through it cannot be sucked in. evenly expanded and overlaid with rows of grate surfaces (4). These grate surfaces are connected in the suction space (7) of the pump at the top by an integral baffle part (6) for catching loose liquid droplets. In the separator fluid there is a flow regulator (12) which, by means of a rod (10), controls the flow through the suction port of the pump (11) located at the end of the separator at its lowest point.

The device is for separating various gases from liquids in a flow-through manner. For this separation, boiling of liquids can also be achieved in the apparatus.

So far small amounts of different gases in liquids are very difficult to remove. For example, waste water with a certain amount of ammonia cannot be discharged into watercourses, and the usual method of dispensing is expensive in the present case.

The flow-through gas separator according to the invention is also suitable for equalizing the pressure differences between the liquid reservoir and the high vacuum in the pump suction so that the liquid flowing through it cannot be sucked in. For this purpose, the alignment part is overlapped by rows of grate surfaces and the space in the alignment part is multiplied many times. The rows of grate surfaces are also spaced one after the other in the suction space of the pump. At these locations, they are connected at the top by a single baffle portion to retain the released portions of the liquid. The liquid in the separator is equipped with a float regulator which controls the flow through the suction port of the pump located at the end of the device in its lowest part by means of a rod.

Various gases are separated from the liquids by the flow separator device in the same way as the liquid boils. This is achieved by the fact that the high inlet velocity of the liquid flowing into it, caused by the pressure difference, is reduced by the impact on the grate surfaces and by a very large widening of the flow cross section. In this way, it is possible to reduce the inflow velocity of, for example, 12 m / s to 0.05 m / s, which is necessary for perfect gas separation. Their separation takes place mainly behind the wide grate surfaces, whose centers receive relatively little liquid, which is a large area for gas evacuation. When gas is sucked off, droplets of liquid may escape, which in any case are heavier than the mass of the gas. However, these droplet droplets are rectified by the integral baffle portions of the flat gratings and therefore, due to their inertia in motion, strike the other surfaces of the integral baffle portions and lead them back into the flowing liquid. In order to prevent the flowing liquid from rising, it is pumped away by a liquid pump located at the end of the inner space in its lowest part and its suction port is controlled by a float.

The device is shown in longitudinal section in the attached drawing. In the atmospheric pressure liquid reservoir 1 there is a flow control regulator 2. The grate surfaces 4 in the equalizing part 2 are for reducing the inflow velocity of the liquid which is distributed laterally. Since the alignment portion 3, which is divided by the rows of grate surfaces 4, is greatly increased, the swirling liquid can no longer regain its original pressure and thus reduce its speed. Because. the released gas passes through many grates, is freed of loose liquid droplets, and the relatively clean gas then enters the first exhaust chamber 5. All exhaust chambers 5 opening into the exhaust chamber 7 are provided with integral rectifying parts 6 on their grating surfaces 4. which are to retain loose liquid droplets. To retain the droplets their inertia is used in the movement in the designated direction. Since the integral baffle portions 6 overlap and determine the direction of movement to the opposite side of the original path, only

-1f gas without heavier admixtures. The gas flows from the suction chamber 7 through the suction tube 8 to the pump or condensation pump.

In order to keep the liquid between the grate surfaces 4 at the same height level, the interior space is provided with a float 9, which controls the flow through the regulator 12 of the suction nozzle of the pump 11 by means of the control rod 10. above it has a contact surface for switching electrical circuits. By closing the contacts, for example, the electromagnetic control valve 2 closes the supply of additional liquid to the buffer part 2 ·

For separating the gas or vapor while boiling the liquid, the separator is longer and the heat for boiling the liquid is supplied by the bottom or possibly through the hollow surfaces of the grates 4.

In particular, the brewing process for the exhaustion of gases or vapors of various substances has many applications and economises the various prior operations. This separator, which is arranged in a flow-through manner, is very small compared to existing systems, and by reducing the pressure for exhaust gas or vapor evaporation, the power is greatly increased at the same power input. For example, in the food industry where it is necessary to concentrate a certain liquid substance by evaporating water and to cook it at a temperature of 80 ° C for a precise period of time and to feed it continuously and accurately at a precise amount into a canning machine. All of this can be achieved in a simple manner by the separator according to the invention. At the exact flow rate of this liquid, the amount of heat supplied is controlled according to the liquid inlet temperature and the precise boiling point is controlled by controlling the pump power.

This work of the device has been achieved by very large and expensive boilers in which parts of the liquid to be treated are damaged by a higher boiling point. In addition, it is difficult to achieve the continuity of the canned liquid and its precise temperature. Moreover, this arrangement is used mostly for high power only, whereas the device according to the invention for its low production cost can be produced for any power.
