Description
Technical field
The invention belongs to field of electric fires, and in particular to a kind of gas-liquid two-phase cooling device.
Background technique
Electric furnace in process of production, temperature of the high-temperature area caused by electric arc up to several thousand degrees celsius, in electric furnace molten bath
Generally also between 1500~1600 DEG C, therefore electric furnace liner temperature is also very high.In order to reduce furnace lining erosion, reduce furnace lining due to
The resistance to material damaged condition of furnace lining caused by alternating thermal stress need to carry out cooling down to it.Electric furnace liner cooling down is main at present
There are two types of modes: by cooling water cooling and passing through cooling gas cooling.Wherein due to technique and operating cost, general electricity
Furnace sidewall is cooling by cooling water, and furnace bottom is cooling by cooling gas；But cooling gas is since density is smaller, room temperature, often
Density is depressed usually in 1~2kg/m3, specific heat is in 1kJ/kg or so, therefore its thermal capacitance ability is limited；The water of same volume with it is cold
But gas absorbs identical heat, and cooling gas temperature increases more than 4000 times of about water；In actual production, we usually meet
To raising cooling gas flow, but cooling capacity is not the case where improving.
In addition, generally also there are two types of the types of cooling in iron runner cooling procedure: by cooling water cooling and passing through cooling air
Body is cooling.Cooling due to its lower operating cost by cooling gas, smaller operation risk is also extensive in iron runner is cooling
Using；It is cooling the same with furnace bottom, using air-cooled iron runner there is also excessively high, the problem of cooling capacity deficiency that exports wind-warm syndrome,
Especially in the case where iron runner ditch lining material corrodes especially severe, the problem is more obvious.
Summary of the invention
In view of this, the purpose of the present invention is to provide a kind of gas-liquid two-phase cooling device, the device combine water cooling and
Air-cooled advantage considerably increases the cooling performance of device, efficiently solve it is air-cooled present in the insufficient technology of cooling capacity
Problem.
In order to achieve the above objectives, the invention provides the following technical scheme: a kind of gas-liquid two-phase cooling device, including cooling tube
Road, cooling pipe are laid at region to be cooled, further include humidifier and mixing tube, and mixing tube one end is connected to cooling pipe
At arrival end, humidifier setting is in mixing tube cooling gas come to end and its gas outlet is connected with mixing tube.
It further, further include controller, temperature sensor and humidity sensor, wherein temperature sensor and humidity sensor
It is arranged at the outlet end of cooling pipe, and temperature sensor and humidity sensor are electrically connected with the controller, controller is again
It is electrically connected with humidifier.
Further, the length of mixing tube is at least five times of its diameter.
Further, mixed tube diameter is greater than cooling pipe diameter.
Further, discharge outlet is equipped at the rear end bottom of mixing tube.
Further, discharge outlet is connected by pipeline with the water inlet pipe of humidifier.
The beneficial effects of the present invention are: the humidifier in the cooling device is by cooling water atomization to generate droplet, droplet
It is mixed in mixing tube with cooling gas, mixed gas, mist are when flowing through required cooled region, on the one hand by cooling gas pair
Stream heat exchange absorbs the heat in cooled region；On the other hand, droplet also absorbs heat from cooled region by the way that evaporative phase-change occurs
Amount.In the case where retaining the advantage that air-cooled operating cost is lower, safety is good, by the micron order atomized drop of addition, greatly
The cooling capacity for increasing system greatly, solves the insufficient technical problem of cooling capacity existing for traditional air cooling system.
Detailed description of the invention
In order to keep the purpose of the present invention, technical scheme and beneficial effects clearer, the present invention provides following attached drawing and carries out
Illustrate:
Fig. 1 is the structural diagram of the present invention.
Specific embodiment
Below in conjunction with attached drawing, a preferred embodiment of the present invention will be described in detail.
As shown, the gas-liquid two-phase cooling device in the present invention, including cooling pipe 3, cooling pipe 3 are laid in electric furnace
Region to be cooled at, further include humidifier 1 and mixing tube 2,2 one end of mixing tube is connected at the arrival end of cooling pipe 3, separately
Cooling gas is accessed in one end, and the cooling gas that mixing tube 2 is arranged in humidifier 1 is come to end and its gas outlet and mixing tube 2
It is connected.
In the cooling device, by cooling water atomization to generate droplet, the cooling gas for being blown into mixing tube 2 is passing through humidifier 1
It is uniformly mixed in mixing tube 2 when crossing humidifier 1 with droplet, uniformly mixed droplet and cooling gas are flowing through required cooling zone
When domain, the heat in cooled region is on the one hand absorbed by cooling gas heat convection；On the other hand, droplet is by occurring evaporation phase
Become, also absorbs heat from cooled region.At 30 DEG C of room temperature, the evaporation latent heat of water is 2424kJ/kg, and air is in room temperature 30
DEG C when specific heat be about 1kJ/kg；In cooling procedure, evaporating absorbed heat by droplet is about phase homogenous quantities cooling gas
Temperature increases 2424 times of 1 DEG C of absorbed heat.
It should be noted that: by selecting then humidifier, it is allowed to generate micron-sized droplet, on the one hand, micron-sized droplet
Its transpiration-cooled specific surface area can be greatly increased, to be conducive to the rapid evaporation of droplet, improves the cooling capacity of device；Separately
On the one hand, micron-sized droplet can also effectively prevent the droplet not being evaporated to form a large amount of liquid water in cooling device.
It as a further improvement of the foregoing solution, further include controller 6 and signal transducer 4, signal transducer 4 herein
For temperature sensor and humidity sensor, wherein temperature sensor and humidity sensor are arranged at the outlet end of cooling pipe 3
Place, and temperature sensor and humidity sensor are electrically connected with controller 6, controller 6 is electrically connected with humidifier 1 again.
Specifically, the temperature sensor of 3 outlet end of cooling pipe and humidity sensor, which is arranged in, can correspond to detection cooling tube
