Description
Technical field
The present invention relates to a kind of formaldehyde fumigation sterilization method, the invention further relates to a kind of formaldehyde fumigation chlorination equipment.
Background technology
The formaldehyde fumigation disinfection way for using at present is to add in rustless steel container formaldehyde, and container is placed on support, is used
Alcolhol burner is heated, and formaldehyde is evaporated in the method for indoor fumigation, and the shortcoming of the method is that operation link is cumbersome, there is safety
Hidden danger：The method need to be lighted after alcolhol burner, and operating personnel just may exit off room, and now formaldehyde has begun to volatilization, can be right
The operator's health not withdrawn from a room produces influence, or even causes formaldehyde poisoning symptom, severe formaldehyde poisoning entail dangers to life；
Alcolhol burner is naked light, easily causes disaster hidden-trouble.
The content of the invention
In order to solve the above mentioned problem existing for prior art, the invention provides a kind of formaldehyde fumigation sterilization method and its
Chlorination equipment, is carried out disinfection using chemical principle, and it can be very good to control the time of contact of formaldehyde and potassium permanganate, to make
Formaldehyde reaction is complete, it is ensured that formaldehyde liquid noresidue is reaching the effect to the fumigation of closed room；Make formaldehyde and Gao Meng
Sour potassium is reacted after operating personnel open 30 seconds of valve, and the time for leaving clean room is reserved to operating personnel, and
And whole disinfecting process avoids the generation of naked light, it is ensured that the safety of operating personnel.
The technical scheme is that so constitute：
A kind of formaldehyde fumigation sterilization method, it is characterised in that comprise the following steps：Formalin is through formaldehyde trench bottom aperture
It flow to the formaldehyde transfer pipeline with valve；Opening valve makes formalin flow into time delay groove and control formalin flow velocity size；
Formalin is flow in time delay groove through formaldehyde transfer pipeline；When height of the formalin in time delay groove reaches spillway hole highly
When, formalin flows out from spillway hole, flow in the potassium permanganate groove equipped with potassium permanganate solid；Formalin and potassium permanganate
Solid contact is reacted, formaldehyde gas release, and fumigation is carried out to closed room.Described formalin concentration is
36%, the liquid-solid ratio of formalin and potassium permanganate solid is 25:1(V：W)；At least through 30 seconds formalin after opening valve
Beginning reacts with potassium permanganate solid.
Present invention also offers a kind of chlorination equipment for above-mentioned formaldehyde fumigation sterilization method, it is characterised in that including
Formaldehyde groove, support, potassium permanganate groove, time delay groove and formaldehyde transfer pipeline, the formaldehyde trench bottom depressed area are provided with aperture；It is described
The bottom of formaldehyde groove is fixed on above support；One end of the formaldehyde transfer pipeline is connected to formaldehyde trench bottom and is communicated with aperture,
The other end of formaldehyde transfer pipeline is stretched into potassium permanganate groove sidewall, and lower section is provided with the time delay for being fixed on potassium permanganate trench bottom
Groove；The formaldehyde transfer pipeline is provided with valve；The time delay groove side is provided with spillway hole.
Preferably, the interior diameter ratio of hole diameter and formaldehyde transfer pipeline is 1:10.
Preferably, the time delay groove is cylinder or cuboid, and formaldehyde transfer pipeline stretches into length in potassium permanganate groove sidewall
Spend the cell body without departing from time delay groove.
Preferably, the spillway hole is highly apart from time delay trench bottom 1-1.3cm, a diameter of 0.2- of spillway hole
0.4cm。
Preferably, the formaldehyde groove is cylinder；Support is square or cuboid, and at least one side is movable to tear open
Unload；Potassium permanganate groove is rectangle or square.
Preferably, one end of the formaldehyde transfer pipeline is welded on formaldehyde trench bottom and is communicated with aperture, and hole diameter is
1.0mm, the interior diameter of formaldehyde transfer pipeline is 1.0cm.
Preferably, it is a cuboid after support and the combination of potassium permanganate groove.
Preferably, the chlorination equipment material is stainless steel.
The present invention has buffered the reaction of formalin and potassium permanganate solid by time delay groove, and spillway hole therein is even more control
The time of formalin and potassium permanganate solid contact is made, clean room has been left there is provided the time to operating personnel.
Now inventor is described as follows in the development of existing equipment：
Experiment for the first time is improved：
It is electrically operated valve that the present invention is initially use, due to inconvenient operation, electrically operated valve is removed afterwards, installs hand-operated valve
Door, realizes artificial control chemical reaction.The method is simple and convenient, but it is still very violent to chemically react.
Second experiment is improved：
The hole diameter of formaldehyde trench bottom depressed area is set to 1.5mm；Valve is opened, and formalin 2-3s flows into permanganic acid
In potassium groove, there is acutely chemical reaction.
Third time experiment is improved：
The hole diameter of formaldehyde trench bottom depressed area is improved to by 1.0mm using the drill bit redrilling of 1.0mm, reaction is acute
Strong degree is substantially reduced.
Inventor is found that while that response intensity can be controlled by improving hole diameter, but general clean area fumigation
All put the formaldehyde fumigation chlorination equipment of more than 2, can not be reached if only above-mentioned improvement is carried out operating personnel safety from
The effect at the scene of opening, being then determined as the present invention increases time delay groove, delays the reaction time of formalin and potassium permanganate solid,
Reach operating personnel and leave the requirement reacted after clean room.Comprise the following steps that：
A. assume that operating personnel need the time of 30s to withdraw stifling scene, measuring formalin by beaker passes through formaldehyde
The liquid volume of transfer pipeline stream 30s calculates the volume of time delay groove.
B. because flow into time delay groove formalin volume exceed time delay sump volume when take place chemical reaction, it is necessary to
Gap, control formalin outflow time delay groove and the time of potassium permanganate solid reaction are outputed in the corresponding position of time delay groove, lead to
Overtesting determines a diameter of 0.2-0.4cm of gap, makes valve that chemical reaction takes place by the time of 30s after opening, this
Can just there is the safe escape time of 30s after sample operating personnel opening valve.4th experiment is improved：
Appropriate formaldehyde and potassium permanganate are poured into formaldehyde groove and potassium permanganate groove respectively, meter is started while opening valve
When, chemically reacted after 30s, illustrate that time delay groove and gap can reach the effect for delaying above-mentioned reaction.But off-test
Find to remain formaldehyde in time delay groove afterwards, illustrate not reacted fully.It is fully anti-to reach to need adjustment spillway hole height
The requirement answered.
The height (h spillway holes) of computation delay groove spillway hole, measurement reaction terminates the height (h mixing) of rear mixed solution,
React the formalin in time delay groove then needs h mixing ＞ h spillway holes completely.
Mix removing residue formaldehyde solution conditions in the time delay groove poor with h spillway holes different height, experiment knot by testing measuring and calculating h
Fruit is shown in Table 1.Experiment explanation h mixing should be higher than that h spillway holes 15mm, and to reach, the reaction of the formalin in time delay groove is complete to be required,
Determine that spillway hole is highly 1-1.3cm.
