If bubble enters the performance that can influence pump in above-mentioned first circulation pump 8 and second circulation pump 11, and feed liquid is into excessively above-mentioned air
Gas-liquid separation when kettle 18, when the gas in above-mentioned air kettle 18 is more than certain limit, the air outlet valve at 18 top of above-mentioned air kettle
19 automatically open and detach the gas in kettle, to make the feed liquid entered in above-mentioned first circulation pump 8 and second circulation pump 11 not have
There is bubble.
In the present embodiment, further include demister in above-mentioned vaporising device, above-mentioned demister is set to above-mentioned annular hydrojet
1 top of pipe, wherein since in above-mentioned explosive evaporation area 13, boiling will produce many foams to feed liquid, when foam is excessive, above-mentioned ring
The non-boiling feed liquid that nozzle on shape sparge pipe 1 sprays can not be fallen directly into the feed liquid of lower section, and understood some and accumulated
In the foam, it is discharged not only bad for forming non-boiling area and steam and can not be successfully from above-mentioned steam (vapor) outlet 5, therefore, works as bubble
Foam, which rises through above-mentioned demister, makes the gas in foam and drop separation, gas are discharged from above-mentioned steam (vapor) outlet 5, under drop
It falls, to improve production efficiency.
The evaporator and vaporising device of the utility model, by increasing above-mentioned annular sparge pipe 1 and towards in above-mentioned tank body
The said nozzle 2 of wall makes above-mentioned cavity be divided into spraying zone 3 and non-spraying zone 4, and above-mentioned explosive evaporation area 13 is positioned at above-mentioned non-
In spraying zone 4, above-mentioned explosive evaporation area 13 is set not contacted with above-mentioned inner tank wall, and the feed liquid of above-mentioned spraying zone 3 is constantly washed away
Above-mentioned inner tank wall, so as to avoid accumulation forms caking on the inner wall of above-mentioned evaporator after the feed liquid evaporation of boiling；Pass through
Air kettle is added in above-mentioned lower circulation pipe 10, the feed liquid entered in above-mentioned first circulation pump 8 and second circulation pump 11 is made not have gas
Bubble damages pump so as to avoid bubble the working efficiency and service life for influencing pump.
The above is only the preferred embodiment of the present invention, and it does not limit the scope of the patent of the present invention,
Equivalent structure or equivalent flow shift made by using the description of the utility model and the drawings, is directly or indirectly transported
Used in other related technical areas, it is equally included in the patent within the scope of the utility model.
