Description

The invention relates to heat engineering equipment of boiler houses, heat networks, central heat points and heat centers of buildings, and can be used to trap, precipitate and remove mechanical impurities during operation of this equipment.

The purpose of the invention is to increase the degree of purification of the environment from contamination.

The drawing shows a schematic circuitry.

A storm ring consists of a vertically placed body 1, an inlet nozzle 2, an outlet nozzle 3, a breakdown cone 4, a central pipe 5, slots 6, plates 7, nozzles 8 for cleaning and faucets 9 for draining sludge.

Gr serge is as follows.

The coolant entering the body 1 with a scaprost V0 is lowered onto the fender 4 and smoothly spreads over the entire cross section of the body. The coolant flow smoothly flows around the first plate along the course and rotates 180 °, resulting in particles of contaminants separating and settling to the bottom of the sludge cup. Then the coolant flow passes in the space between the plate 7 and the central tube 5 and through slot 6, the output pipe 3 goes further to the heat network

The space between the plate generator and the central tube provides the laminar flow regime of the medium, i.e., a speed of 0.05 m / s or less. As a result, the required degree of cleaning of the medium from pollution is provided

The flow of coolant for the second and subsequent plates is significantly reduced and the degree of purification of the coolant from contamination increases

In a sandbox, mechanical particles of pollution fall out in the process of turning the flows through 180 ° around the forming plates under the action of gravitational (gravity) and pushing (Archimedean) forces. This force difference is counteracted by the resistance force of the medium, which is significantly reduced under the plates due to the creation by making cuts in

cavity of laminar flow regime plates.

The condition of guaranteed deposition of mechanical particles of contamination is determined by the size of the gap between the plates, the number of plates, the size of the particles and the speed of deposition of particles.

An additional degree of purification of the medium is achieved by the formation of a stagnant zone between the body and the central tube, from which the sediment cannot be carried away by the flow of medium from the body.

In addition, decreasing slot lengths, equal to the depths of adjacent plates along the heat carrier, ensure equalization of the hydraulic head between the housing plates themselves, which increases the overall cleaning ratio of the gearbox.

The removal of sludge is carried out through the faucets 9, and clearing through the nozzles 8 during the period of repair or shutdown of the system.
