Abstract

The invention relates to a power system and can be used to preheat water with waste gases. The aim of the invention is to increase reliability by simplifying the design. The heater contains a gas outlet 1 and a gas supply pipe 2, separated by a longitudinal partition 4 into sections 5 and 6 with irrigation nozzles 7 and 8, a horizontal partition, an overflow device made in the form of pipes 10, 11, 12 and 13, a transverse partition 14 with windows 15, forming a gap 17 with the walls of the housing. Under the horizontal partition there is a moisture collector communicated with the sprinkler 21 and equipped with a heat sink device. The flue gases, having passed through section 5, are directed through nozzle 7, windows 15, a gap 17 into pipe 1. Washing the nozzle 7, the gases dry it and give it their heat. Section 6 is filled with water to the level of overflow pipe 13, and section 5 is dry. During the irrigation of the nozzle 8, heat is removed from it and discharged into a moisture collection chamber, from which cooled water enters section 5 and 6 in turn. The overflow device plays the role of a hydraulic lock during irrigation. 2 Il.

The invention relates to a power system and can be used to heat water with waste gases.

The aim of the invention is to increase reliability by simplifying the design.

FIG. 1 shows a water heater, a cross-section; in fig. 2 is a section A-A in FIG. one.

The heater contains a housing 3 provided with an upper gas discharge 1 and a gas inlet 2 branch pipes, divided by a vertical longitudinal partition 4 into sections 5 and 6 with irrigated nozzles 7 and 8 mounted on a horizontal partition 9, and an overflow device, filled in pipes 10-13. The casing 3 has a vertical transverse partition 14 with windows 15 and 16 in the lower part, which forms a gap J with the walls of the casing 3.

The partition 14 is adjacent to the partition 9 and in the zone of windows 15 and 16 to the ends of the nozzles 7 and 8. The gas supply pipe 2 is located above the nozzles 7 and 8, and the gas outlet pipe 1 is connected to the gap 17. The pipes 10-13 are fixed in the partition 9, a continuous continuous one, the upper section of pipes 11 and 13 being located between nozzles 1 and 2 and nozzles 7 and 8. Under the partition 9 there is a moisture collector 18 connected via line 19, equipped with control valves 20, to sprinklers 21 and 22 nozzles 7 and 8. The moisture collector 18 is also equipped with a heat sink device 23, -.

 The water heater works as follows.

Hot flue gases are fed to the nozzle 2, from which they are sent to section 5 and, after passing through the desiccation 7, the windows 15, the gap 17, discharging it through the tubing 1. The gases, washing the nozzle 7, drain it and give it their heat . At the same time, section 6 is filled with water — up to the upper cut of pipes 13, and section 5 is dry.

During the heating of the nozzle 7, the nozzle 8 is irrigated, which transfers its heat to the heated liquid. Irrigation water in section 6,

it fills it up to the level of pipe 13 and is poured into the moisture collector 18. At the same time, the water along the pipe 12 is also drained into the moisture collection 18. The cross section of the pipes 12 and 13g, as well as 10 and 11 is selected so as to eliminate the water inlet of the pipe 2.

After the heating time of the nozzle 7, the valve 20 on the sprinkler 21 opens and the valve 20 on the sprinkler 22 closes. Section 5 is filled with water, which draws heat from the heated nozzle 7, and section 6 is emptied. In this case, the overflow device fulfills the role of a water seal and prevents gas from entering the moisture collector 18. The irrigation process of sections 5 and 6 occurs cyclically. The heated water gives off its heat to the device 23 of the heatsink and cooled water is supplied to the nozzle irrigation.
