The upper tube box includes upper tube tank shell, and the top of the upper tube tank shell is equipped with collection gas port, is set on the down tube tank shell
There is the second air inlet, the collection gas port, the second air inlet are connected to by pipeline；
The step（2）In, stoste steam enters heat exchanger tube from horn mouth, wherein most of stoste steam enter inner tube with
In gap between outer tube, also fraction stoste steam is entered from lower gas vent in inner tube, between inner tube and outer tube
The stoste steam in gap is contacted with outer tube to which heat exchange is condensed into the stoste of liquid rapidly, and the proportion of stoste is more than stoste steam,
To which stoste flows down from the first air inlet and enters lower tube box, into inner tube a stoste steam part enter from air admission hole it is interior
It exchanges heat in gap between pipe and outer tube, partial condensation is run down into from lower gas vent in lower tube box at stoste, remainder
Stoste steam then enters upper tube box from upper air-vent, then by pipeline from collection gas port be delivered to the second air inlet, again into
Enter into lower tube box, continues to condense operation.
7. condensation method according to claim 5, which is characterized in that the condensation of the steam forced circulation and vacuum energy-saving
Device further includes spray water tank, which includes down tube tank shell, which is equipped with stoste steam inlet, under this
Top in bobbin carriage shell is equipped with spray equipment, and the bottom of the lower tube box is respectively equipped with stoste outlet, the spray water tank respectively with
The spray equipment, stoste outlet are connected by pipeline；
The spray equipment includes cyclic annular spray tube and the connecting tube that is connected to the ring-type spray tube, the connecting tube and the shower water
Case is connected to by pipeline, and the ring-type spray tube is horizontally disposed, and spray apertures are evenly distributed on the tube wall of the ring-type spray tube；
The stoste for the liquid gathered in down tube tank shell is extracted by stoste outlet, and is existed by the spray apertures on spray equipment
It is sprayed in down tube tank shell, stoste steam is made first once to be exchanged heat before entering heat exchanger tube, reduce the temperature of stoste steam,
Part stoste steam is directly condensed into liquid stoste.
8. condensation method according to claim 5, which is characterized in that be equipped with the first liquid level in the lower part of the heat exchanger shell
Meter is equipped with second liquid level gauge in the top of the heat exchanger shell, which is located at the lower section of the cloth liquid disk；
When the coolant liquid liquid level in the heat exchanger shell reaches at the second liquid level gauge, coolant liquid is extracted out from outlet tube, directly
When reaching at the first liquid level gauge to coolant liquid liquid level, stop coolant liquid extraction action.
