SU1224532A1 - Contact water heater - Google Patents

Description

The invention relates to industrial heat engineering and can be used to heat water in contact machines.

The aim of the invention is to increase the reliability of the contact water heater by increasing the degree of cooling of g, the basics and their drying.

The drawing shows a contact water heater.

The contact water heater contains a vertical housing 1 with an upper outlet 2 and a lower supply 3 gas nozzles.

A funnel-shaped tank 4, connected to the water supply system 5, irrigator 6, nozzle 7, located on the support grid 8 and equipped with discharge pipes 9, a cascade of inclined distribution ramps 10 and a water collection bin with TRUs 12. Upper skates 10 placed with a gap relative to the walls of the housing 1 and is made with the direction of the slope from the center to the periphery. The lower slope is also made with the direction of the slope from the center to the periphery, perforated with holes 13 and fastened with peripheral edges to the housing 1. Slab 10, except the extreme top, is made with central openings 14 and decreasing from one to another. .

river dimensions. Ramps 10 can be made corrugated.

Contact water heater works as follows. 5 Cold water is supplied through the water supply system 5 to the funnel-shaped tank 4 and further to the irrigator 6, which irrigates the nozzle 7. At the same time as the water supply through the supply gas pipe 3, hot gases are supplied, which give part of the heat to the pipes 12, passage through them, and further sent to the central openings 14 of the slopes 10. The passage through the gaps between the slopes 10, the gases enter the nozzle 7 and into the discharge pipes 9 and are removed through the exhaust gas nozzle 2. The heated in the nozzle 7 water flows into the slopes 10 and through the bottom hole 13 skate 10 enters moisture bilberry 11, where it is sent to the consumer. When it comes to slopes 10 from nozzle 7, water flows down along the film, while the stack goes from one slope to another, water constantly contacts with hot flue gases of the same temperature, which increases its heating. Moist flue gases leaving the area wash the funnel-shaped container 4, further reduce their temperature, and the moisture contained in them condenses to drain. nozzle 7.
