Description

The invention relates to equipment for the wet cleaning of gases from dispersed particles with sprayed water and can be used, in particular, in installations for separating polymers when cleaning a vapor-gas mixture from polymer chips, for example, rubber.

The purpose of the invention is to increase the reliability and efficiency of the device, as well as to increase the separation efficiency.

FIG. 1 shows the structure of the proposed device; in fig. 2 - flushing distribution unit

Noah water.

The device contains a vertical cylindrical body 1 with an expanded upper section 2, a pipe 3 for supplying the dusty gas mixture a pipe 4 for discharging the cleaned gas mixture, a pipe for supplying washing water 5 and its drain 6. In the extended section 2 there is a conical fairing 7, along the periphery of which installed louvered plate ring separator 8.

Along the height of the cylindrical body 1, means 9 are installed for distributed fluid supply, comprising a supply pipe 10, nozzles Vnpuri 11, flow dividers 12 with an upper cone 13 provided with helical grooves 14, and a lower cone 15 mounted in a bearing 16 which is placed free wheeling. The upper cone 13 is introduced into the diffuser 18 of the Venturi nozzle 11 with a gap of 19.

The device works as follows. (Consider the case of using a device to clean a vapor-air mixture from rubber crumbs coming from a horizontal dryer - a vibroconveyor of the LC line to the entrance of an exhaust fan of a vapor-air mixture outlet system from a department of discharge).

ka, through pipe 3 enters the cylindrical part of the device and rises in the opposite direction to the swirling films of water forming the conical surface of rotation.

Upon contact with the conical surfaces of water films, fine particles of rubber that are in the flow of the vapor-gas mixture are captured by the liquid and are thrown onto the cylindrical surface of the housing 1, flow along it and are removed through several conical surfaces of rotation of the WATER films; the vapor – gas mixture is completely cleared of rubber crumbs. Proceeding further into the ring-shaped separator 8, the vapor-gas mixture is dried and removed from the apparatus through the nozzle 4.

It goes through the supply pipes 10, passes through the Venturi nozzles 11 and enters the screw grooves 14 of the upper cones 13 of the dividers 12 and the gap a.

Owing to the reactive forces arising during the movement of water along the screw grooves 14, the spreaders spin up. In this case, the water flowing from the upper cones of the dividers 12 forms rotating cones-sprays, which overlap the cross-section of the housing 1, upon contact with which the vapor-air mixture is cleared of small crumb of rubber.

The proposed device, with minimal hydraulic resistance, will ensure that crumbs of rubber and water do not get into the vapor-air mixture drainage system from the separation plant. At the same time, the rubber crumb will be completely recovered from the installation and returned to its production cycle.

In the device, the process of mass transfer is carried out mainly by contacting the vapor-gas mixture with swirling films of water oriented in inclined planes to the gas flow, and the separators, in addition to washing with water, are also cleaned by centrifugal forces caused by the rotation of the dividers. In addition, the placement of a louvered separator along the periphery of the cone fairing 7 makes it possible to achieve a uniform load of the separator with minimal hydraulic resistances.
