Side is provided with condensation-water drain A, and opposite side is provided with steam inlet A, and described tank base sets
There is sewage draining exit.
Further, upper and lower two parts of described tank body are sealed even by end socket adpting flange
Connect.
Further, described formaldehyde fumigation pot bottom is provided with supporting leg.
Further, described tank base connects sewage draining exit by valve.
Further, described tank body is additionally provided with Pressure gauge.
The present invention is claimed a kind of side being carried out sterilizing by above-mentioned formaldehyde fumigation tank simultaneously
Method, the method comprises the steps: by compressed air hose, compressed air is passed through tank base,
Then formaldehyde enters room by formaldehyde conveying pipe under compressed-air actuated effect, passes through steam inlet
A is passed through steam PARA FORMALDEHYDE PRILLS(91,95) in tank interlayer to carry out heating and being incubated, by steam inlet B to set
Doing auxiliary heating by steam in pipe clamp layer, the condensed water of steam passes through condensate port A, condensate port
B discharges, and the dirt of tank interior is discharged by sewage draining exit.
Beneficial effects of the present invention is as follows: the formaldehyde fumigation jar structure that the present invention provides is simple, make
With convenient, enter each room for pure formaldehyde gas, then efficient by room
Air-supply reaches sterilization effect, and the pipeline installation electromagnetic valve entering room can control formaldehyde gas respectively
The inlet of body, and when using, do not have the phenomenon of formaldehyde crystallization, there is operation safety, go out
The feature that bacterium is effective.

Detailed description of the invention
As it is shown in figure 1, a kind of formaldehyde fumigation tank, by supporting leg 6 stable stand on ground,
Tank body is provided with formaldehyde inlet 11 and heat-insulation layer A 4, and compressed air inlet pipe 2 is passed through tank body
Bottom, tank body top connects formaldehyde conveying pipe 1, described formaldehyde conveying pipe by control valve 7
It is cased with heat-insulation layer B 9 outside 1, between formaldehyde conveying pipe 1 and heat-insulation layer B 9, forms cannula clamp
Layer 10；Described heat-insulation layer A 4 forms tank interlayer 8 with tank body；Heat-insulation layer A 4 side is provided with
Condensation-water drain A 12, opposite side is provided with steam inlet A 13；Heat-insulation layer B 9 is provided with cold
