Water collecting tank heating unit, sewage collecting tank heating unit include fluid heater 1 and circulating-heating circuit, specifically, at this
Fluid heater 1 is fuel heater in embodiment, and fuel heater provides heating fluid by being heated to anti-icing fluid, that is, is added
Hot fluid is anti-icing fluid, thus is avoided that when fuel heater is shut down heating fluid freezes, it is of course also possible to use conduction oil is made
To heat fluid.Fluid heater herein refers to that the heater that fluid is heated can be mainly used for exporting high temperature
Fluid.
As shown in Figure 3 and Figure 4, the bottom in the outside of tank body 9 is equipped with seal closure 6, and seal closure 6 is the external shape fits of tank body 9
And the arc-shaped cover of the length direction extension along tank body, each side of arc-shaped cover are sealedly connected on the outer wall of tank body 9, thus with
The outer wall of tank body 9 surrounds the heat conduction inner cavity for accommodating heat-conducting fluid, and heat-conducting fluid is full of in entire heat conduction inner cavity, in this implementation
Heat-conducting fluid specifically uses conduction oil in example.The both ends of seal closure 6 are all provided with, there are two slotting, can adapt to phase on tank body 9 in this way
The mounting structure answered.In the serpentine-like heat conduction inner cavity for being distributed in arc panel and being surrounded with tank body 9 of heating pipeline section 7, enhance add in this way
Hot pipe section 7 and the contact area of heat-conducting fluid, improve the efficiency of heating surface.The straightway of the heating pipeline section of snakelike distribution is received along sewage
Collect the length direction extension of tank, thus be avoided that and excessive bend pipe is set, reduce the resistance of heating fluid flow.Outside seal closure 6
Side is equipped with thermal insulation layer 8, and thermal insulation layer 8 is specifically made of the heat insulation foam for being wrapped in 6 outside of seal closure in the present embodiment, reduces heat
Loss, improve the efficiency of heating surface.
Heating pipeline section 7 is transferred heat to by heat-conducting fluid on tank body 9, increases thermal conductive contact area in this way, is heated
Uniformly, the efficiency of heating surface is significantly improved, and can also shortens the length of heating pipeline section 7 to a certain extent in this way, reduce heating
The resistance that fluid flows in pipeline section 7 is heated reduces energy consumption.Pipeline section 7 will be heated in the present embodiment is arranged on 9 outside of tank body
Bottom, it is more convenient in this way to be conducive to heat the sewage in tank body 9, because sewage can be concentrated under gravity in tank body 9
To the bottom of tank body 9.
