Description

one

The invention relates to devices for the purification of gases from liquid particles and may find application in the chemical, oil refining, food, metallurgical and other industrial sectors.

The purpose of the invention is to increase the separation efficiency by reducing secondary entrainment.

FIG. 1 is a schematic representation of a spray trap, vertical section; figure 2 - section aa on. figure 1; on fig.Z - a fragment of the package, a horizontal section ;; figure 4 - section bb in fig.Z; on - view B on fig.Z; figure 6 - a separate visor.

The sprinkler includes a housing 1 with a lid 2, a diffuser 3, and an infusor 4, to which the inlet 5 and outlet 6 are attached. Package 1 contains a package 7 consisting of parallel plates 8, resting on a grid 9 located in the lower part of case 1. The drain fitting 10 is attached to the case. Trapezoidal holes 11 arranged in a staggered manner are attached to the case 8. The vertical edges of the holes 11 are attached to the peaks 12, made in the shape of a rectangular trapezoid, the large base 13 of which is connected to the vertical edge of the hole, and the inclined side 14 is located at the bottom at an angle dt 5-25. Peaks 12 are installed at an angle of 30-45 to the plane of the plate. Holes 11 in adjacent plates are offset relative to one another in such a way

that the surface of the other plate is located against the hole of one plate.

The drip tray works as follows.

The gas along with the liquid particles through the inlet 5 enters the housing 1, where, having passed the diffuser 3, it enters the bag 7. The passage through the latter, the gas makes a long zigzag path due to the arrangement of the holes 11 in a checkerboard pattern, the presence of inclined canopies and the displacement of the holes adjacent plates. When a stream collides with the surface of the plates and visors, the liquid particles settle on them and flow down in the form of a film into the lower part of the housing 1. The location of the inclined side 14 of the visor 12 at the bottom at an angle of 5-25 ensures a continuous flow of the liquid film along this edge, indicating a sharp Kapleunos in the specified range.

By trapping liquid particles, an air purification efficiency of about 90% is achieved. When the angle of inclination decreases (less than 5 °), the cleaning efficiency drops sharply to 65–70%, and with an increase (over 25), the cleaning efficiency begins to decrease due to the smaller degree of overlap of the holes due to the lengthening of the inclined side. The installation angle of the visors also influences the character of the flow of the flow between the plates. 1 The best values for droplet separation efficiency are observed in inter

Claims (2)

1. SPRAY catcher containing a housing and a package of parallel plates placed in it with staggered trapezoidal holes with visors, the holes in adjacent plates being offset relative to each other so that the solid surface of the other plate is opposite the hole of one plate, and the visors are opposite parties, characterized in that, in order to increase the separation efficiency by reducing the secondary droplet, the visors are made in the form of a rectangular trapezoid, more whose base is connected to the vertical edge of the hole, and the inclined side is located below at an angle of 5-25 ° to the horizontal. 2. Spray catcher according to claim 1, characterized in that the visors are installed at an angle of 3045 ° to the plane of the plate. >
