Description

. Devices for thermal descaling of water are known, which consist of a cylindrical boiler supplied with distribution distributor. for water with several rows of plates for heating with water vapor in a thin layer and with a trigger pipe for MUTI UNDER.

In the proposed device, a horizontal partition and 3 several rows of plates are placed to trap dregs from the water on the way after the sieve.

In FIG. 1 depicts the relative position of the faucet and evaporator; FIG. 2 is a cross-section of the device; FIG. 3 is the same in longitudinal section, Fig 4, 4 in three projections of the plate, over which the water discharged from the tolus is distributed; FIG. 5, 5, view in three projections of the plate for retaining the turbidity.

In the upper part of the device (Fig. 2 and 3) there is a gullet /, into which the pump and water under pressure equal to the date (in the device {4 atmospheres) and above are driven. . The groove serves to distribute the zod over the plate 2 (Fig. 4). Water i. erasers poured

in broad jets, it flows downward but in a zigzag path, forming a large area of contact between it and the vapor that fills the upper part. The steam heats the water and condenses as it does. Steam is introduced into the device from one end through hole 70. At the other end, through hole / 7, continuous air is blown to remove air released from the water when it is heated, and carbon dioxide formed from decomposition of temporary hardness salts together with some steam. The solid residues formed from the decomposition of temporary hardness salts when water is heated 135-140 ° (or higher), in the form of small crystals, are partially deposited on the plates. Water flowing down the plates is co6HpaetcH into chute 3, from which it goes downward through pipe 4 down into a crushing line, 5, in which additional sludge occurs. From the horizontal siphon-baffle 6, the water is directed to the end of the cylindrical part of the device, from where it flows to the other end of the scoop. In order to detain the turbulence that is possible to remain completely in the water, a plate .iCTHHbi 7 is located on the path of its movement (Fig. 5). By stratifying the flow of water into several layers having a small height, the turbidity is delayed on these plates.

The device is equipped with a purging hole 72 from the mud 5 that settled in it, a hole (5) for flushing when cleaning the plates 7 from the turbidity settled on them, a hole in the safety valve, and a laser 75 to pull the plates 2 outwards and to clean them from yakipi. In addition, there is a hatch 76, which is opened for the duration of the cleaning to ventilate the device.

The booster is equipped with a float / m regulator 17 Sfig. 1), supporting the water level and acting on the valve on the pipe from the pump, and the water-measuring glass 7, as well as with the safety claine (fHa drawing not shown). :

The device does not require any maintenance during operation, except for the periodic blowing of the sieve 5 (twice a day) and cleaning it from scale. This will be produced in approximately fifteen days of continuous operation. To clean the boiler. from the operation by overlapping the respective valves, and hot water is discharged through the vent hole 12.

The Blender is then cooled by passing cold water through it & and at the same time the opening of the manhole 75 and the hatch 76 is made. Through the manhole 75, a worker climbs inside the boiling pan, removes one after the other plate 2 and feeds them to another worker who is outside; the latter, turning the plates, easily releases them from loose; scum.

After cleaning, the -2 plates are put in place. Then the cleaning of the 7in is performed with a jet of water from the hose. The washings are washed out with water and removed through the hole / 5. Then the doors are closed and the device is again ready for operation. Duration of cleaning is two hours per hour.

The subject matter of the invention.

A device for thermal purification of water from scale, consisting of a cylindrical boiler, equipped with an internal 55. three distribution trough for water with several rows of plates. To heat the water in a thin layer and a drain pipe for turbidity under it, characterized by the use of a horizontal partition 6 and located in several rows of plates 7 for trapping dregs from the water on the way after the sieve 5.
