Liquid chlorine enters into safety groove through the liquid inlet, safety groove is filled with rear liquid chlorine and is progressed into each vaporization tubulation, hot water in the water bath containers is in the liquid chlorine of temperature conduction to each vaporization tubulation, makes the vaporization of being heated of liquid chlorine, and the chlorine after the vaporization is discharged from gas outlet.As everyone knows, the boiling point of agene is than high (71 ℃ of the agene boiling points of the boiling point of liquid chlorine, liquid chlorine boiling point-34 ℃), and common the requirement about 45 ℃ of bath temperature that is used for improving liquid chlorine saturation vapour pressure, hence one can see that, in the process of liquid chlorine vaporization, most agene is failed vaporization and is deposited in the remaining liquid chlorine.Generally, because the design deficiency of technology and equipment structure, remaining liquid chlorine is less, so the relative concentration of agene is higher, has the danger of blasting above 5%.Improvements of the present invention just are, set up the safety groove that connects liquid inlet and each vaporization tubulation, have increased the amount of remaining liquid chlorine after the vaporization, thereby have reduced the concentration of the agene of deposition, have improved Security.In addition, the beneficial effect of setting up safety groove also is, has avoided making the agene of deposition to be in for a long time heated condition, has reduced the outside inducement that agene is blasted, and has further improved Security.
All be provided with fluid level controller in the common liquid chlorine vaporizing unit, produce continuously with raising automatic production level and realization, but work as liquid chlorine vaporizing unit structure not simultaneously, the setting position of fluid level controller is also different.In liquid chlorine vaporizing unit proposed by the invention, fluid level controller is positioned at the vaporization container, and is controlling the liquid chlorine feeding valve that is connected with the liquid inlet, automatically controls liquid chlorine gas-liquid face height in the container of vaporizing according to need of production.Particularly, the information gathering end of fluid level controller can be hydrostatic sensor, and hydrostatic sensor can be positioned at safety groove, thus the liquid level height in the Real Time Monitoring vaporization container.
In order to improve further novel chlorine vaporizing unit proposed by the invention, in above-mentioned vaporization container, set up the dashpot that connects each vaporization tubulation upper end and gas outlet, below the gas outlet of dashpot, safety valve is set, thereby prevent that liquid level is too high and overflow, the liquid chlorine of avoiding not vaporizing is discharged from gas outlet.When because fluid level controller is unusual or set incorrectly when causing liquid level to arrive safety valve, and unnecessary liquid chlorine can be discharged from safety valve, safety valve sends signal simultaneously, closes liquid chlorine feeding valve.
Similar with common water bath principle, water bath containers heats each vaporization tubulation by the hot water that passes into set point of temperature among the present invention, and changes the hot water of set point of temperature according to environment in good time.The effect of water outlet is can the incrustation scale of deposition be discharged by water outlet when water bath containers service time is longer, stop rapidly heating water bath thereby maybe can hot water be discharged by water outlet, before water-bath begins, also need by water outlet the cold water in the water bath containers to be discharged.When water outlet was closed, it was excessive to pass into for fear of hot water, and container pressure is excessive, can set up flow-off to discharge excessive hot water in the water bath containers upper end.
