Description

113083532

The invention relates to apparatuses of the supercavitation cavity for the degassing of a liquid and may be (caverns). used in the chemical, petrochemical industry, in the energy sector for the degassing of make-up water, heat gas liquids 5, liquid degassing networks, feed water is desalinated, and the gas from the caverns of the disposal plants, as well as through the valve 5 by means of a vacuum system, for example a vacuum pump. Execution of the outer surface

Since the pressure in the cavity is less than the partial pressures of the dissolved

engineering apparatus for degassing

binder and reinforcing material

used for the manufacture of a ballo-cavitation element of waves or high-pressure reactor vessel housings allows to obtain more

degassing surface developed in comparison with the known device,

pressure. The purpose of the invention is to increase the capacity and quality of the treatment of the liquid through its physical modification.

Figure 1 shows a device for degassing, a general view; figure 2 - node I in figure 1; on fig.Z - section aa in figure 2.

A device for degassing a liquid includes a circulation pump 1, a regulating valve 2, a working section 3, a container 4 for collecting liquid, a valve 5 for evacuating gas from the liquid being degassed, and a cylindrical pipe 6. Along the axis of the working section 3, which is a circular pipe on the ground 7 is reinforced

the magnitude of which can be regulated by changing the magnitude of the difference between the radial protrusion 9 and the depression 10 o The larger it is, the more developed the degassing surface and vice versa.

Element 8 can also be made in the form of an impeller with wavelike blades,

With an increase in the degassing surface, the degassing rate increases, which means that the capacity and quality of the liquid treatment.

The results of laboratory tests of the proposed device show that, compared with the known surface degassing, ceteris paribus,

the cavitation element 8, for example, co-30 catches (the power of the pump 1, the length of the pipe, the outer surface of which would be 6, the tank 4) increases by

made wavy with conjugate radial protrusions 9 and depressions, 10, located along the axis of the working section 3, B-body of the cavitation element 8 provides channels 11, which are connected through the internal cavity of the rod 7 and valve 5 with a vacuum system. The device also contains a confuser 12 and a valve 13 for draining degassed liquid.

The device for degassing Ldkost works as follows

Using a circulation pump 1, the degassable fluid through the valve 2 and the confuser 12, in which the required flow velocity (5–15 m / s) and the drop in static pressure is reached, is supplied to the working section 3, where during flow past the element 8 attached to floor rod 7, supercavitational cavities (cavities) form. liquids of gases, the liquid is degassed, and the gas from the cavity is removed through the valve 5 by means of a vacuum system, for example, a vacuum pump. Execution of the outer surface

Since the pressure in the cavity is less than the partial pressures of the dissolved

the magnitude of which can be regulated by changing the magnitude of the difference between the radial protrusion 9 and the depression 10 o The larger it is, the more developed the degassing surface and vice versa.

Element 8 can also be made in the form of an impeller with wave-like blades,

With an increase in the degassing surface, the degassing rate increases, which means that the capacity and quality of the liquid treatment.

The results of laboratory tests of the proposed device show that, compared with the known surface degassing, other things being equal

The oxi x (power of pump 1, length of pipe 6, tank 4) is increased by

35–40%, productivity — by 25–30%, and quality of liquid treatment (degree of degassing) —8–10%, if 35 over 100% takes the amount of gas to be removed in the same time in the known and proposed devices.
