Flow the weak filtrate storagetank.
Further, the heat sink includes feed liquor portion, goes out liquid portion and some tubules, some tubule both ends difference
With the feed liquor portion with it is described go out liquid portion be connected, and be arranged in parallel, and with interval；It is described go out liquid portion include tapping bucket and going out
The necking connection of liquid pipe, outlet tube and tapping bucket；The feed liquor portion includes feed liquor bucket and inlet tube, the contracting of inlet tube and feed liquor bucket
Mouthful connection, the bottom of feed liquor bucket connect with one end of some tubules, and if the bottom of feed liquor bucket diameter more than described in
The summation of dry capillary diameter；Bottom of the other end of some tubules respectively with the tapping bucket is connected, and the bottom of tapping bucket
Portion's diameter is more than the summation of some capillary diameters.
Further, the tubule for connecting feed liquor bucket is 30-50 root tubules, which is thin-wall metal pipe, and aperture is
3- 5cm, length 1-2m, the distance between tubule are more than 10cm.
Further, logical cold wind or logical cooling water outside tubule.
Using technical solutions of the utility model, has the following advantages：The aluminium oxide square position filtering washing lotion of the utility model is followed
Loop system replaces condensed water to rinse filter cloth using weak filtrate, has saved condensation water consumption, alleviates the production burden of process,
Production consumption is reduced, reduces operating cost.Weak filtrate is delivered to horizontal table filter to hydrogen again after heat sink cooling
Alpha-alumina crystals wash, and drop few water vapour volatilization, avoid big calorimetric highly basic water vapour from volatilizing, and hot highly basic water vapour volatilization is not only
The waste of resource, while be also the pollution to atmospheric environment.
