Description

The invention relates to devices for cleaning compressed gases from dropping liquid in compressor units, pneumatic drives, steam boilers, and can be used in various areas of national economy, for example, in power engineering, metallurgy, the building materials industry, and in the chemical industry.

The aim of the invention is to increase the efficiency of trapping liquid components.

Figure 1 shows a device for separating liquid components from compressed gas, longitudinal section; figure 2 - section aa in Fig, 1; Fig. 3 shows a section BB in Fig. L; FIG. 4 is a net bag.

The device has a vertical cylindrical body 1 with an internal body; an inlet pipe 3, an output pipe o4, a condensate collector 5. In the center of the case 1 a shaft 6 is vertically mounted with tubular wheels 7 and longitudinal rotor blades 8 mounted on it bearings 9 and 10.

The stationary cylinder 11 encloses the turbine wheel 7 and has tangential slots 12 opposite it,

The vertical cylinder of the chamber 13 encloses the cylinder 11, perforated in a proper manner along the length of the rotor blades 8 by holes 14. The perforation of the cylinder 11 of camera 13 is made by holes 14 with dimensions increasing from top to bottom, about 5 to 15 mm. The increase in the size of the openings 14 is caused by the elimination of the possibility of overflowing of compressed gas through the internal cavity of chamber 13 from the bottom up, besides the main amount of the separated liquid is carried out in the lower part of chamber 13, in the lower part of chamber 13 there is an intermediate condensate collector 15, the blades of the rotor 8 - the end condensate collector 16, the drain pipes 17 and 18 with hydraulic locks 19 and the drain pipe 20, In the lower part of the tank 1 there is a partition 21, and in the end condensate collector 16 - a partition and 22 mounted on the shaft 6, the rotor blade Over 8, on the side in the rotational direction of the reinforced net bags 23 pie shape.

The mesh bag; the 23 is made of about 0.5-1 mm in diameter wire with 3-5 mm mesh openings and an external fixing frame that is designed to prevent deformation of the mesh bag.

The device works as follows

The gas-liquid flow through the inlet 3 is introduced tangentially into the vertical cylindrical body 1, whereby the flow makes circular motions in the body 1. pipe 2 to the tangential slot m 12.

Through the slots 12, the compressed gas enters CI.PINDR 1 1, a turbine wheel is driven to rotate and 6 rotor blades 8 are located on the same shaft, where the action of the rotating blades 8 and the mesh bags 23 fixed on them 23 combines two processes: coagulation, , coarsening of fluid particles as a result of their merging during collision both with each other, and when colliding with the wire of the mesh bag 23, and centrifuging, i.e., under the influence of centrifugal force, the enlarged droplets of fluid in the radial direction,

Separated. dropping liquid through the holes 14 of the cylinder 11 enters the chamber 13, then flows into the intermediate condensate collector 15, and from it through the drain valve 18 of the hydraulic lock. 19 - to the condensate collection unit 5, from which the liquid components are periodically drained through the pipe 20,

The cleaned compressed gas through the outlet 4 is supplied to the consumer, and the liquid extracted from the gas is pressed from secondary entrainment by squeezing with gas with partitions 21 and 22.

B starts-shsh period of operation of the device or when it stops, when the rotor blades 8 still do not have the desired rotational speed, part of the dropping liquid can get into the end, condensate collector 16. And in this case, the separated liquid through the drain pipe 17 through the hydraulic lock

19 also enters the condensate trap 5.

The proposed device performs a more complete purification of the compressed gas (air) from the dropping liquid due to combining several processes: circular flow in the housing 1 with dropping the dropping liquid on its walls (the first cleaning stage), as well as combining coagulation and centrifugation when the coarsening of the fluid particles as a result of their merging, both in the collision of the mesh bag 23 with the wire, and in the collision of these particles with each other due to the disordered movement of the gas flow, on complex paths during its movement through the reticulated bystrovraschayuschies packets aggregated with the removal of liquid droplets in the radial direction due to centrifugal force (second cleaning step). In addition, the energy of compressed gas (air) flow is used to drive the shaft 6 of the turbine wheel 7 and the rotor blades 8.
