Abstract

Использование: теплоэнергетика, система отоплени и гор чего водоснабжени , контактный нагрев воды. Сущность изобретени : в корпусе 1 размещены два сло 4 и 5 орошаемой насадки. Нижний слой 4 установлен на опорной решетке 6 и имеет газоперепускной патрубок 7, а также перфорированную пластину (ПП) 8 и концентрично расположенные в теле сло перфорированные обечайки 9. Перфорации в последних и в ПП 8 выполнены с переменным проходным сечением, увеличивающимс в первых в сторону опорной решетки 6. а в пластине - от центра к периферии. Газ поступает в спой 4 насадки через патрубок 7 и далее, огиба торцы обечаек 9, неоднократно мен ет направление движени внутри сло 4. Из последнего в слой 5 насадки газовый поток поступает через ПП 8. 4 ил.Usage: heat power system, heating and hot water supply system, contact heating of water. SUMMARY OF THE INVENTION: Two layers 4 and 5 of an irrigated nozzle are placed in the housing 1. The bottom layer 4 is mounted on the support grid 6 and has a gas transfer pipe 7, as well as a perforated plate (PP) 8 and perforated shells 9 concentric in the body of the layer. support grid 6. and in the plate - from the center to the periphery. Gas enters nozzle nozzle 4 through nozzle 7 and beyond, envelopes the ends of shells 9, repeatedly changes the direction of movement inside layer 4. From the latter, gas stream flows into nozzle layer 5 through PP 8. 4 sludge.

Claims

The claims

A CONTACT WATER HEATER comprising a vertical casing and an upper outlet and lower supply ducts and located between the latter with the formation of an intermediate opening of at least two layers of the irrigated nozzle, the lower of which is mounted on a support grid and equipped with a gas outlet, characterized in that to increase the efficiency of the heat transfer process

in order to increase the contact time between j media, the lower layer of the nozzle is equipped with a perforated plate placed above it and concentric perforated shells inserted into its body, fixed with ends alternately on the support grid and perforated plate, with the formation of gaps between the last and free ends of the shells, with perforations in the plate and in the shells are made with a variable cross-section, increasing, firstly, from the center to the periphery, and secondly, towards the support grid.
