Description

(St) SEPARATOR

The invention relates to separators used to separate a liquid from a gas, and can be applied in chemical engineering. A separator for separating methanol from gas is known; it contains a vertical casing with a bottom, provided with openings for gas and methanol output, covered from above with a lid with a pipe for inlet of a gas-liquid mixture attached to it, the lower end of which is immersed in liquid methanol 1 Closest to the proposed the technical essence and the achieved result is a separator comprising a vertical casing with openings for gas and liquid outlet, a coaxial tube for introducing the cleaned gas, the lower end of which is immersed in a liquid bone, cone mounted outside the pipe | 2. A disadvantage of the known separators is that they do not provide a degree of separation of impurities from the gas, which is necessary for modern production, whose work is characterized by a long catalyst run. Under these conditions, even minor impurities of carbonyl iron in the gas lead to accumulation on the catalyst surface. fine elemental iron, as a result of which the catalyst produces not only methanol, but also methane. Insufficiently effective operation of the separator reduces the efficiency of the entire production of methanol. The purpose of the invention is to increase the efficiency of separation of liquid from gas to improve its quality. This goal is achieved by the fact that the separator, which includes a vertical casing with openings for gas and liquid output, a coaxial pipe for introducing the gas to be cleaned and a cone, is equipped with a coaxial but installed above the cone with a multi-turn screw thread, a settling cylinder and a cylindrical cone shell, while the settling the cylinder is attached to the cone, and the lower edges of the cone and shell are immersed in the liquid.

The drawing shows a separator.

The separator comprises a housing 1, which is closed on top with a lid 2 with a central opening 3 for introducing a gas-liquid mixture. Holes t and 5 are drilled in the body thickenings at the top and bottom for the outlet of gas and liquid. A tube 6 is attached to the lid 2 for the introduction of purified gas. Its lower end is plugged from the end and provided with perforations. In the upper section of the pipe 6, a swirler 7 is fastened, equipped with a multi-way screw thread. It is placed with a small gap in the cavity of the settling cylinder 8. From below, the cylinder 8 rests on the flange of the inner cone 9, which with its notches is attached to the plates 10, which are attached to the housing 1. From above, the cylinder 8 is clamped by a ring 11, which is fastened to the plates with the help of bolts TO, which are attached to the housing 1. From above, the cylinder 8 is clamped by a ring 11, which with the help of bolts is attached to the flange of the shell 12. The latter with its lower edge rests on the cone 9. The lower portions of the cone 9 and the shell 13 are located below the level of the liquid in Lost casing and form a gap with the housing,

The settling cylinder is made of a material that provides the movement of fluid from its inner surface to the outer one. For this purpose, various materials permeable to liquids can be used: foam rubber, multilayer nets — steel or from plastic filaments. The cylinder 8 can also be made by sintering various grains, for example, grains of thermosetting resins. The material for the manufacture of the cylinder and other parts of the separator must have the necessary stability in the medium of gas and the separated liquid.

The separator can be manufactured for pressures up to 350 atm and more.

The separator works as follows.

The gas-liquid mixture to be separated through the pipe 6 enters the body cavity. Through perforation

the lower portion of the pipe 6, the gas-liquid mixture enters the liquid layer. The gas is bubbled up, the liquid is attached to its layer, which is located in the body cavity. When gas bubbles rise upward, carbonyls of iron are released from it and dissolve.

Then the gas passes at high speed with the grooves of the multi-way screw thread, where, under the action of centrifugal forces, liquid droplets are seized from it, trapped by it as it leaves the liquid layer. The separating liquid is deposited on the cylinder 8, moves onto its outer surface and, downwardly, connects to the liquid in the body cavity. The gas, having undergone a multi-threaded thread, is directed into the holes 4 and covers the separator.

In the proposed construction, an additional separation gas from the liquid layer is used, the swirling channel of the swirler passes with great speed and twists. Under the action of the resulting centrifugal forces, liquid droplets are separated from the gas, which pass to the outer surface of the droplet deposition cylinder, flow down, and combine with the liquid in the lower part of the separator, thus ensuring high quality gas separation.
