Description of drawings
Fig. 1 is a structural representation of the present invention, and Fig. 2 is the vertical view of evaporimeter, and Fig. 3 is the evaporimeter front view.
The specific embodiment
As shown in Figure 1, devaporizer of the present invention, one water tank 1 is arranged in its lower end, the top of water tank 1 is provided with the air intake 5 that is made of shutter, de-icer 2 is installed in water tank 1, and axial fan 13 is installed in the upper end, is being positioned at installation secondary heat exchange layer 4 on the air intake 5 above the water tank 1, secondary heat exchange layer 4 is made of the honeycomb filler, and evaporimeter 14 is installed above secondary heat exchange layer 4.
As Fig. 2, shown in Figure 3, the tube bank 14 that evaporimeter 14 is arranged by staggered triangular pitch ' forms, restrain 14 ' two ends be installed in respectively about two bobbin carriages 14 " in.As shown in Figure 1, with pipeline bobbin carriage 14 " is separately installed be cooled the fluid intake valve 7 and the fluid issuing valve 8 that is cooled; respectively at the fluid intake valve 7 that is cooled; fluid issuing valve 8 and bobbin carriage 14 are cooled " on two pipelines that communicate between on thermometer 9 and Pressure gauge 6 are installed, at bobbin carriage 14 " on temperature sensor 10 is housed; shower water pipeline 17 is installed above evaporimeter 14; whenever keeping at a certain distance away has nozzle 11; water inlet of shower water pipeline 17 connects with the delivery port of water pump 23; water inlet of water pump 23 communicates with the filter 24 of water tank 1 on shower water pipeline 17; installation one PVC separator 12 above shower water pipeline 17, axial fan 13 is installed in the top of PVC separator 12.At the evaporimeter outer wall peephole 15 is installed.On the inwall of water tank 1, scribble one deck wear-and corrosion-resistant coating 3.Splashproof row 19 is installed on air intake 5 next doors.
As shown in Figure 1, the water inlet of shower water pipeline 17 is connected on the delivery port of hydrotreater 18, and the water inlet of hydrotreater 18 is connected on the water pump 25.One electromagnetic type water level meter 22 is installed on the sidewall of water tank 1, is connected with two magnetic valves 21 of control to water tank 1 supplementing water.Bobbin carriage 14 at evaporimeter 14 " on a pipeline is installed, an air bleeding valve 16 is installed on this pipeline.
