Abstract
The utility model discloses a liquid nitrogen water circulation device which mainly comprises a liquid nitrogen storage tank, a liquid nitrogen vaporizer, a hot water storage pool, a cooling tower, a cold water storage pool and a brazing furnace. The liquid nitrogen vaporizer is installed in the hot water storage pool. The cooling tower is installed above the cold water storage pool. According to the principle of the liquid nitrogen water circulation device, hot water in a water cooling section of the brazing furnace is led to the liquid nitrogen vaporizer and the liquid nitrogen vaporizer is heated through the hot water, so that liquid nitrogen inside the liquid nitrogen vaporizer is fully vaporized, the liquid nitrogen vaporizing efficiency is improved, and the liquid nitrogen consumption is reduced. Meanwhile, the hot water discharged out of the water cooling section of the brazing furnace is preliminarily cooled, the preliminarily-cooled hot water becomes cold water after being cooled again through the cooling tower, and the cold water is pumped into the water cooling section of the brazing furnace and used for cooling a product device. According to the liquid nitrogen water circulation device, the phenomenon that a large amount of the liquid nitrogen is consumed and wasted due to the fact that the liquid nitrogen vaporizer is frozen can be prevented and the purpose that the cooling water can be supplied for cooling the device can be achieved as well, so that the water use rate is improved through mutual circulation, and the purposes of energy conservation and environment protection are achieved.
Description
Technical field
The utility model relates to one and prevents that liquid nitrogen vaporizer from freezing, and can be the liquid nitrogen water circle device of soldering oven cooling.
Background technology
When continuous tunnel furnace high temperature brazing operation, must guarantee the inner oxygen content < 0.001% of burner hearth, therefore must, to the high-purity normal temperature nitrogen of annotating in burner hearth, guarantee that product is at high temperature not oxidized.Product welds stokehold and need to be cooled through high temperature furnace, and now cooling temperature is very important, the too low deformation of products that causes of chilling temperature, chilling temperature is too high, can cause product to be come out of the stove after remaining Wen Taigao operative employee is caused to potential safety hazard.And water-cooled (soldering oven water-cooled section) just can address this problem completely, if by cooling water through apparatus for supercooling, then reaching chilling temperature by discharge control can be too not high or too low.Nitrogen is the high inert gas of volatility, aerial content exceedes 70%, during for industry, nitrogen is separated from air, for just as store, the nitrogen being separated is compressed into liquid state, when use, again liquid nitrogen is vaporized by liquid nitrogen vaporizer, because liquid nitrogen temperature is extremely low, a large amount of heat around vaporizer absorption in the process that is converted into gaseous state, force ambient air temperature to decline, the condensation of airborne moisture chance is formed the globule and is adsorbed on evaporator surface, when temperature continues to drop to freezing point, the evaporator surface globule congeals into ice, cover above vaporizer, make liquid nitrogen vaporization decrease in efficiency, also increased the consumption of liquid nitrogen simultaneously.
summary of the invention
The utility model object is to provide one to prevent that liquid nitrogen vaporizer from freezing, and can carry out cooling water circle device to soldering oven product.
for achieving the above object, the technical scheme that the utility model is taked is:
A kind of liquid nitrogen water circle device, mainly comprises the filling of liquid storage nitrogen, liquid nitrogen vaporizer, hot water cistern, cooling tower, cold water cistern and soldering oven, it is characterized in that: described liquid nitrogen vaporizer is arranged in hot water cistern; Described cooling tower is arranged on cold water cistern top position; A suction pump is installed between hot water cistern and cooling tower; Cold water cistern is connected with pipeline with soldering oven water-cooled section, is also connected with a suction pump in the middle of it.
the utility model has the following advantages:
1, the utility model has solved easily icing problem of vaporizer in liquid nitrogen vaporization process, improves liquid nitrogen vaporization efficiency, has reduced the loss of liquid nitrogen.
2, the utility model easily can also, for soldering oven provides cooling water, improve the utilization rate of water in icing problem solving vaporizer, has saved water resource and reached the object of energy-conserving and environment-protective.
3, the utility model is easy to operate and with low cost.
Accompanying drawing explanation
Fig. 1 overall structure figure of the present utility model.
The specific embodiment
as shown in Figure 1:a kind of liquid nitrogen water circle device, mainly comprises liquid nitrogen storage tank 1, liquid nitrogen vaporizer 2, hot water cistern 3, cooling tower 4, cold water cistern 5 and soldering oven 6, and described liquid nitrogen vaporizer 2 is arranged in hot water cistern 3; Described cooling tower 4 is arranged on cold water cistern 5 top positions; A suction pump 7 is installed between hot water cistern and cooling tower; Cold water cistern 5 is connected with pipeline with soldering oven 6 water-cooled sections, is also connected with a suction pump 8 in the middle of it.
When device work, first open the liquid nitrogen fluid stop valve of liquid nitrogen storage tank 1, temperature passes through pipeline flow-direction liquid nitrogen vaporizer 2 at the liquid nitrogen of subzero 198 degrees Celsius, flow in hot water cistern 3 by pipeline to the hot water of product facility cooling from the water-cooled section of soldering oven 6 simultaneously, because liquid nitrogen temperature is extremely low, a large amount of heat around liquid vaporizer 2 absorptions in the process that is converted into gaseous state, force ambient air temperature to decline, the condensation of airborne moisture chance is formed the globule and is adsorbed on liquid nitrogen vaporizer 2 surfaces, when temperature continues to drop to freezing point, liquid nitrogen vaporizer 2 surface water drops congeal into ice, hot water in hot water cistern 3 can be heated and prevent icing formation liquid nitrogen vaporizer 2, also accelerated the vaporization of liquid nitrogen, reduce the loss of liquid nitrogen.The nitrogen of having vaporized is delivered to and is used terminal 9 by pipeline.Hot water in hot water cistern 3 through with liquid nitrogen vaporizer 2 in liquid nitrogen to carry out heat exchange tentatively cooling, be arranged on suction pump 7 between hot water cistern 3 and cooling tower 4 by hot water be extracted in cooling tower 4, carry out again cooling.Cooling good cold water flows in cold water cistern 5, by being arranged on suction pump 8 between outlet conduit and soldering oven 1 inlet channel of cold water cistern 5, the cold water in cold water cistern 5 is transported in soldering oven 1 and is lowered the temperature for equipment and product.Flow control apparatus for water is installed in soldering oven, and discharge control reaches chilling temperature can be too not high or too low, guaranteed the quality of product.
Although above-described embodiment is to the mentality of designing of the present utility model detailed text description of contrasting; but these text descriptions; just the utility model mentality of designing simple text is described; rather than restriction to the utility model mentality of designing; any combination, increase or modification that does not exceed the utility model mentality of designing, all includes in protection domain of the present utility model.
