Advantage of the present utility model and beneficial effect are:
1, this horizontal spray film evaporator, red liquid enters evaporator shell by shower, evenly spray is to the upper liquid film that forms of the superiors' pipe of heating tube group, liquid film produces heat exchange with the interior steam of pipe, thereby lower boiling part water in red liquid is undergone phase transition and become steam, and the liquid not undergoing phase transition pools drop and drops onto on lower one deck heating tube in heating tube bottom, and drop when heating tube upside moves downward, can on heating tube outer wall, form liquid film and with pipe in steam generation heat exchange, repeat the heat exchanging process of ground floor pipe until fluid drips drops out heating tube group, steam enters heating tube group by vaporium and with the outer red liquid heat exchange of pipe and be condensed into water, condensed water is pooled in the water tank of right side and sends, water in red liquid undergoes phase transition the secondary steam of generation and is sent by the road by case top steam.
2, this horizontal spray film evaporator, adopts one group of nozzle consisting of nozzle body and water conservancy diversion bolt, and body enters the water conservancy diversion bolt of first flowing through after nozzle body, through water conservancy diversion bolt effect liquid, becomes rotation status; The liquid of rotation forms uniform circular distribution face by the bottom ejection of nozzle body; And because the outlet at bottom of nozzle body is little compared with nozzle body import, therefore liquid locates to obtain higher flow velocity again, make the liquid of ejection present spray pattern; And can there is flash distillation in the very first time in the atomized liquid spraying through nozzle, the part water in the much more popular liquid of band, a booster action to red liquid evaporation; Red liquid through nozzle ejection is uniform circle, and cloth liquid is even, and the efficiency of evaporimeter is improved a lot.
3, the utility model scientific structure design is reasonable, adopts horizontal spray film mode, makes red liquid realize full flashing when entering evaporimeter inside, and then carries out falling film evaporation, and heat exchange efficiency is high; Tube side is walked in heating steam, and required medium amount is little, and energy consumption is low, after the outside fouling of heating tube group, is easy to cleaning, is a kind of horizontal spray film evaporator with higher innovation.
