Technical field
This utility model belongs to silicon dioxide hydrolysis stove technical field, is specifically related to a kind of silicon dioxide aerosol
Chiller.
Background technology
Silicon dioxide hydrolysis stove is one of topmost equipment in silicon dioxide producing device.From nozzle reaction with
After aerosol under the effect of negative pressure from top to bottom enter hydrolysis stove, in body of heater through with as cooling
After the air heat-exchange of medium, flow out from the discharging opening of bottom of furnace body, aerosol be minimized temperature to adapt to after
The technological requirement of continuous operation.
The hydrolysis stove of prior art, owing to structure configuration is not reasonable so that containing the heat of mixing of silicon dioxide
Gas can not be sufficiently cool, it is impossible to meets and produces needs, on the other hand there is also cooling gas and the wave of time
Take, add production cost.
Such as Chinese patent ZL 201420489689.4, the practicality of entitled " silicon dioxide hydrolysis stove " is new
Type patent, open a kind of silicon dioxide hydrolysis furnace structure of knowing clearly, including the body of heater of jacketed, the material of this body of heater
Entrance is for cutting sth. askew to entrance, and the entrance of chuck, for cutting sth. askew to entrance, is cut sth. askew to the most right for two.The height of this patent
Temperature silicon dioxide aerosol enter from the top of body of heater body of heater with the cooling air heat-exchange entered chuck, but
It is that its body of heater cavity is in the most through structure so that high temperature silica aerosol the most only flows through
The extremely short time, then the most directly filling and let out furnace bottom outflow, the structure of this heat exchange causes high temperature titanium dioxide
Silicon aerosol is short owing to spending the stream time in body of heater, adds that its heat exchange area is little, so heat transfer effect is poor, high
Temperature silicon dioxide aerosol can not cool to required temperature.
Summary of the invention
Technical problem to be solved in the utility model is, overcomes the silicon dioxide hydrolysis stove of prior art to exist

Silicon dioxide aerosol prolongs cooling Bottomhole pressure from top to bottom, cooling medium, and i.e. cooling air is from lower
On in the flows outside of cooling tube, both become countercurrent flow relation to configure, and the advantage of countercurrent flow is to work as bar
When part is identical, the logarithmic mean temperature difference (LMTD) of countercurrent flow is all bigger than other all of heat exchange modes, and especially ratio is suitable
Stream heat exchange is much greater, and countercurrent flow can make hot fluid cool down most effectively.
Cooling tube is arranged by helical form, greatly extends the distance that silicon dioxide aerosol flows through, Ye Jiyan
Grow the time of heat exchange cooling, in other words, for same heat transfer effect, so that it may the structure making body of heater is tighter
Gather, volume smallerization of body of heater.
Cooling tube is arranged by helical form, the high temperature fluid of crooked position flowing in spiral helicine cooling tube, its
Flow velocity near kernel of section position fluid is less than the flow velocity of the fluid near cross section outside left, if slightly disturbing
Dynamic, easily form turbulence effects, in other words, lateral fluid hybrid switching in being formed, this is for higher temperature
Fluid flow to wall with improve heat transfer effect be highly advantageous.
Prolong tangentially connected air inlet pipe joint, it is to avoid kinetic energy rejection is caused in Fast Cooling gas direct collision furnace wall,
And make cooling fluid be prolonged diagonal upward direction spiral flow by face, furnace wall guiding, i.e. expand and described serpentine pipe
Time of contact, improve heat exchange efficiency.
Preferred version, feed pipe prolongs and is tangentially connected with bell, and discharge nozzle prolongs and is tangentially connected with bottom of furnace body.
Preferred version, cooling tube is parallel with 2-3 root.
Preferred version, the cooling tube of described 2-3 root parallel connection is pressed point intervals such as multiple start thread form and is arranged.
The beneficial effects of the utility model are:
1, countercurrent flow can make hot fluid cool down most effectively；
2, drastically increase the distance that silicon dioxide aerosol flows through, namely extend the time that heat exchange cools down,
More compact structure and the miniaturization of body of heater can be made；
3, form turbulence effects in being beneficial to cooling tube, improve heat transfer effect；
4, tangentially connected air inlet pipe joint, it is to avoid high-speed gas kinetic energy rejection, and make cooling fluid by furnace wall
Face guides prolongs diagonal upward direction spiral flow, improves heat exchange efficiency.
