Description
Technical field
The utility model relates to a kind of for the liquid of high temperature corrosion is carried out fast cooling device, belongs to the fast prompt drop of high-temp liquid
Temperature technique field.
Background technology
Corrosivity refers to the physics between metal and environment and chemical interaction, makes metallicity change, causes metal,
The phenomenon that environment and composition thereof sustain damage.Corrosion is a kind of physical electrochemistry change.The type of corrosion can be divided into wet etching
With dry etching two class.Wet etching refers to metal corrosion in the presence of water, and dry etching then refers in the presence of without aqueous water
Dry gas in corrosion.Owing to air generally containing water, Chemical Manufacture also often processes the various aqueous solution, the wettest
Method corrosion is modal.
Wet etching refers to metal a kind of electrochemical reaction in aqueous.An anode region and negative electrode is formed in metal surface
Separate from corrosion cell, metal loses electronics in the solution, becomes the ion of positively charged, and this is an oxidizing process i.e. sun
Pole process.Meanwhile in the metal surface of the contact aqueous solution, electronics has a large amount of chance to be neutralized by certain material in solution,
The process neutralizing electronics is reduction process, i.e. cathodic process.Along with the carrying out of corrosion process, as a rule, negative electrode or
Anodic process can be blocked and slack-off, and this phenomenon is referred to as polarization, and corrosion of metal slows down with polarization.
High temperature corrosion is that metal material at high temperature reacts with surrounding medium the destruction caused.Generally according to corrosive medium
State, is divided three classes high temperature corrosion.(1) high-temperature gas dielectric corrosion, commonly referred to high-temperature oxydation, high-temperature gas burn into
Exhaust gas corrosion or dry corrosion etc..(2) high-temperature liquid state dielectric corrosion, is also named high-temp liquid corrosion or heat erosion, including high-temperature liquid
State metal erosion and dissolved salt corrosion etc..(3) high-temp solid dielectric corrosion, is also named high temperature abrasion or erosion.
High temperature corrosion liquid refers at a temperature of more than 260 DEG C, does not cover with strong acid or alkali corrosion body surface thus removal
The region of film protection, reaches the liquid of the appearance graphic needed.
In many processing technology thereofs, need to use the high temperature corrosion liquid handling body surface of more than 260 DEG C, thus reach
Required technological requirement.Because high temperature corrosion liquid has strong corrosivity, and Temperature fall is slow, has influence on life
Produce efficiency, cause the increase of cost.
Summary of the invention
Lowering the temperature problem slowly for high temperature corrosion liquid present in existing high temperature corrosion technology, the utility model provides a kind of energy
Enough make the high temperature corrosion liquid fast cooling device of high temperature corrosion liquid fast cooling.
High temperature corrosion liquid fast cooling device of the present utility model, by the following technical solutions:
This device, including tubulose cooling body, cooling circulating water water inlet pipe and cooling circulating water return pipe, the two of tubulose cooling body
End is connected with cooling circulating water water inlet pipe and cooling circulating water return pipe respectively.
Described tubulose cooling body is spring-like, to increase the contact area in high temperature corrosion liquid.Described tubulose cooling body diameter
10-20cm, the number of turn is 10-15.
The utility model utilizes cooling water circulation that by 260 DEG C, high temperature corrosion liquid is quickly dropped to discharge standard 75 DEG C, it is not necessary to complicated
Safeguard, low cost, safely and effectively.This device and contrast when not adding fast cooling Temperature fall, temperature fall time substantially shortens,
Shorten temperature fall time and reach more than 60%, and decrease operating personnel's workload, improve utilization rate of equipment and installations.

Detailed description of the invention
High temperature corrosion liquid fast cooling device of the present utility model, utilizes the quick fluxion strap of low-temperature circulating water to walk heat, real
Existing high temperature corrosion liquid fast cooling.As it is shown in figure 1, this device includes tubulose cooling body 1, cooling circulating water water inlet pipe 3 and cold
But recirculated water return pipe 4, the two ends of tubulose cooling body 1 respectively with cooling circulating water water inlet pipe 3 and cooling circulating water return pipe 4
Connect.
Tubulose cooling body 1 uses acid and alkali-resistance, resistant to elevated temperatures Teflon Φ 6mm tube material to make, and spirals into spring-like, diameter
The annulus of about 10-20cm, the number of turn, at 10-15 circle, so can increase the contact area in high temperature corrosion liquid.Teflon
Dragon (polytetrafluoroethylene (PTFE) Polytetrafluoroethene, english abbreviation is PTFE) film has excellent heat-resisting low temperature tolerance characteristics
And corrosion resistance, the short time can high temperature resistant to 300 DEG C, typically can use continuously between 240 DEG C～260 DEG C, have notable
Heat endurance, it can work under cryogenic temperature and the most brittle, not melt；It is little affected by medicine to invade simultaneously
Erosion, it is possible to bear except melted alkali metal, fluorinated dielectric and (including higher than all strong acid outside 300 DEG C of NaOH
Chloroazotic acid), strong oxidizer, reducing agent and the effect of various organic solvent, can protect parts from suffering any kind of chemistry
Corrosion.
When needing to lower the temperature to high temperature corrosion liquid, the tubulose cooling body 1 in said apparatus is placed in high temperature corrosion liquid bath 2, and
It is immersed in high temperature corrosion liquid liquid level less than 5.High temperature corrosion liquid bath 2 is the etching tank of equipment, and material is quartz.High temperature corrosion
Liquid level inside high temperature corrosion liquid bath 2 when liquid liquid level 5 is work.Cooling water is made to be entered tubulose by cooling circulating water water inlet pipe 3
Cooling body 1, and discharged by cooling circulating water return pipe 4, form cooling water circulation, lower the temperature.Equipment cavity is required during cooling
Room door is closed, safety operation.When reaching 75 DEG C of emission requests of low temperature of regulation, fast cooling device can be taken out, use clear water
Rinse well, remain use next time.
