SU10214A1 - Apparatus for heating a liquid flowing in a variable amount - Google Patents

Description

The present invention relates to apparatus for heating a liquid entering it, in varying amounts, consisting of a cylinder with two bottoms, heating tubes and lids with nozzles for steam and condensate.

FIG. 1 the apparatus is shown in longitudinal section; FIG. 2 - in cross section.

The housing of the apparatus consists of a cylindrical part 1 and the bottoms 2 and 3 connected to it. Inside the housing are placed heating tubes b, the ends of which are fixed in heights 2 and 3; covers 4 and 5 are attached to the outside; the lid 4 has a nozzle 8 and a cavity 14, the lid 5 has a nozzle 9. A trough 7 is placed above the heating steam tubes b with holes 10 in its bottom and with partitions 11 increasing in height from the middle. The casing has a pipe 12 and holes 13, 15. The device operates as follows. The heated fluid enters through the pipe 12 of the housing 1 into the part of the trough bounded by the abovementioned partitions 11. If the amount of incoming liquid is such that the holes 10,

} G in the bottom of the mentioned part of the trough is enough to flow through the entire amount of the incoming liquid, then, falling on the tubes and the stack through them, the fluid washes only the surface of the tubes that lies under this part of the trough. tube, will occur only at the surface surrounded by liquid. The vapor intended for heating the liquid, having a saturation temperature above the liquid heating temperature, is injected through the pipe 8 into the cavity 14 of the cover 4 and from there it enters the tubes b, where the contact with the part of the surface of the tubes that is washed outside by the liquid condenses. Condensate flows through pipe 9; the heated liquid through the opening 13 and the gases are removed through the opening 15.

The subject of the patent.

An apparatus for heating a liquid flowing in a variable amount, consisting of a cylinder with two bottoms and hardened inside by heating

tubes, and on the outside, lids with nozzles for the supply of steam and condensate drain, characterized in that above the heating and steam tubes 6 there is a trough 7 with openings 10 in the bottom, provided with increasing

the height from the middle to the edges by transverse partitions 11, in order to automatically change the working surface of the heating tubes, with a variable amount of liquid entering through the nozzle 12 to be heated.
