Description

The present invention relates to evaporators, in which, in order to promote the circulation of liquid and the capacity of the devices, it is provided to let in water vapor or a mixture of gas and vapor inside the tubes of the heating drums. In the proposed device with the above purpose, the joint inlet of steam or smbsi of vapor and gas with a vaporized liquid into the heating pipes of the drum is made either through a bell with thin tubes entering the inside of the heating tubes or through obliquely cut unplugged ends of the heating tubes in the bottom of the drum. Steam or cm: Either it is taken from the gas either from the side, or from a special steam generator, - placed, inside or outside the evaporator.

In the schematic drawing of FIG. 1 shows a vertical section through an evaporator with steam supply pipes; FIG. 2 is a vertical section of the apparatus with a steam generator installed on the side; FIG. 3, 4., 6 and 6 are vertical sections of the device with the internal one installed in various parts of it. steam generator; FIG. bottom bottom of the heating drum with obliquely cut ends of the heating t {) slab of FIG. 8 with z-shaped ends of the tubes and FIG. 9 is the same, with a bell and thin tubes in it.

The proposed device consists of a conventional type of evaporator equipped with steam heated tubes 1.1. . . (Fig. 1) through which the liquid to be evaporated circulates. Fire tubes 1.1. . .in the ends of the reinforced two bottoms by rizvaltsovki. After 2, heating steam is supplied, condensate is withdrawn through pipe 3, and non-thickened gases are removed through pipe 4. In the lower part of the apparatus, where the ends of tubes 1 are somewhat released, steam is supplied through pipes 5 through various methods. 6 and 7. Liquid under evaporation enters through pipe 8 and descends through trlbe 9. Under the bottom of the heating chamber a small vapor space is formed. The ends of the heating bodies t |) slaughter 1.1. . . cut at an oblique angle. Fluid and steam, under the same pressure, flow into the heating tubes, mix and fill them. For jiapa rali mix it up with gas, under the bottom

: at the bottom of the bar of the apparatus, an icebreaker A is installed (fig. 9), -03 which collects steam or gas, or a mixture of them, and through the narrow tubes 16 is directed to the heating tube 1.1. . ; Said steam injection can also be modified in such a way that, instead of using a claw A, protruding ends / heating protruding from the bottom, 1.1 tubes. . . obliquely cut (fig. 7) or provided with openings. {fig. 8) with a view through them into tubes 1.1. . . simultaneously, -pair and.

Required for the above mentioned, the target can be supplied to tubes 1.1. . . different ways. Steam can be taken from the side of the pipe 5, and it is also possible to use non-thickened gases removed from the heating pipes through pipes 4 and 7 from the heating pipes. You can also bring. Pi at. assistance E (njektora 11, action: naJJOM: from pipe 4 looking for quiescent steam. Thpy6bf 10: finally, for the same purpose you can use the injector 12, operating with a liquid designed for steaming or; mechanical compressor 13- (Fig. 1). / In addition, the required auxiliary steam may be in the lower part of the apparatus (Fig. 5) from some additional heating surface 3 in the video bar, etc. To generate a sufficient number of steam, the apparatus is equipped outside or inside with a special PA: p) Formation 14-15. In the case when the steam generator is installed at the bottom of the evaporator, as shown in FIG. 2, steam is supplied to the heating tubes 1.1. . . through the pipe 6. When installing the vapor inside the apparatus, it may not be given the shape of a drum evaporator (Fig. 3), a coil (Fig. 5) or a cover, in addition by a cap 4 of the additional temperature 17 (Fig. 6); equally paro4:) the decorator in one form or another will be placed at the top (Fig. 2 and 3),; According to FIG. 4 and 5) or another part of the evaporator. In particular, in FIG. 6 shows an application option within the apparatus of the so-called subsupply additional evaporator. One-way evaporators, for example, 17,

stands out as an auxiliary has a cap 4 on top and below an insulated space, where the liquid is supplied, and auxiliary steam; the newly formed steam is collected under the cap 4 and passes through pipes 6-f5 to the lower part of the adjacent chambers 1 and 3.

The proposed device for increasing circulation in the heating tubes of evaporators can find application to different areas of industry, where it is necessary to evaporate liquid quantities, for example, in sugar, copper, etc., as well as it is adapted to water tube boilers and surface condensers. . In the latter case, its action will take place in the manner described above, with it being necessary only, instead of steam, to supply air. A mixture of air and: water will move at high speed through pipes; water will be heated, partially evaporated, and heat will be removed. Such use of the proposed device to the condenser makes it possible to obtain a smaller heating surface and a reduced coT of the required cold water.,:, -

PROPOSITION OF;

1. A device for increasing circulation in the heating tubes of the evaporators using a steam inlet or a mixture of gas and steam inside each tube, characterized in that a bell A is installed on the bottom of the evaporator drum bottom, equipped with thin tubes, entering the inside of the heating pipe 1 of the drum for admitting a thin jet of steam blown under the bell through pipes 5, 6 or; 7 (Fig. 1) or using the steam injector 11, or the water jet injector 12, or the mechanical compressor 13.,,,

2.To change the device, shown in 1, which differs; m ;, that the bottom bottom of the heating drum is equipped with a protrusion; they obliquely cut (.7) or the end p of the tubes (Fig. 8) these are both a pair and a jndkostn.

3.When the device specified in pp. 1 d.2, application of special 1-steam formation 14 (Fig. 2), connected by TJ) y6oK) 6: with the space under the bottom of the drum p (n distribution of steam over separate heating m {s) d 4. With the device specified in paragraphs 1 and 2, the use of additional steam generator installed inside the same.
