Abstract
The invention discloses a method for vaporizing liquid chlorine by using heat energy produced from sulfur combustion. The method includes the following steps: (i) carrying out mixed combustion of sulfur and air; (ii) carrying out heat exchange with a jacketed heat exchanger; and (iii) vaporizing the liquid chlorine. A water medium is heated by the heat energy produced from sulfur combustion in a bromine production process by an air blowing-out method, and then the heated water medium is used for vaporizing the liquid chlorine; the method fully applies the heat energy produced from the sulfur combustion, effectively reduces the energy consumption and realizes energy-saving and environmental-protection purposes.

Using drusen and air as raw material, in combustion furnace, carry out burning produce sulfur dioxide gas；
() carries out heat exchange with jacket heat-exchanger
Sulfur dioxide gas step () obtained, is passed in the pipeline with multiple jacket heat-exchangers, and sulfur dioxide gas carries out heat exchange with the medium in jacket heat-exchanger；
() vaporization liquid chlorine
Medium through heat exchange in jacket heat-exchanger is passed into chlorine water bath, the tubular heat exchanger in chlorine water bath is heated, makes the liquid chlorine in tubular heat exchanger vaporize, obtain gaseous state chlorine。
It is 300 DEG C～600 DEG C that described step () obtains sulfur dioxide gas temperature。
The plurality of jacket heat-exchanger connects in series。
Medium in described jacket heat-exchanger is water。
Described chlorine water bath is provided with temperature measurer。

The invention has the beneficial effects as follows:
The present invention utilizes the energy heats aqueous medium that in bromine by air blowing-out process technique, sulfur burning produces, then the method carrying out liquid chlorine vaporization with heating aqueous medium again, the heat energy that sulfur burning is produced by the method is applied fully, effectively reduce energy resource consumption, it is achieved the purpose of energy-conserving and environment-protective。
Detailed description of the invention
Method liquid chlorine being vaporized by the heat energy that present invention sulfur burning produces below in conjunction with embodiment is described in detail:
The method that liquid chlorine is vaporized by the heat energy that a kind of sulfur burning produces, comprises the following steps:
() sulfur and air carry out mixed combustion
Using drusen and air as raw material, in combustion furnace, carry out fully burning according to reaction ratio and produce sulfur dioxide gas；
() carries out heat exchange with jacket heat-exchanger
Step () obtaining the sulfur dioxide gas of 500 DEG C, is passed in the pipeline being provided with 2 series connection jacket heat exchanger, sulfur dioxide gas carries out heat exchange with the aqueous medium in jacket heat-exchanger；Sulfur dioxide gas participates in after cooling to 100 DEG C in the reduction reaction of closed acid system Air blowing bromine；
() vaporization liquid chlorine
Aqueous medium through heat exchange in jacket heat-exchanger is passed into chlorine water bath, the tubular heat exchanger in chlorine water bath is heated, makes the liquid chlorine in tubular heat exchanger vaporize, obtain gaseous state chlorine。Being provided with temperature measurer in chlorine water bath, when in water bath, temperature reaches 65 DEG C, the temperature that pipeline pump is fed back controls and stops circulation；After temperature arrives 40 DEG C, the temperature that pipeline pump is fed back controls and starts circulation, and the water in water bath is heated。
The present invention utilizes the energy heats aqueous medium that in bromine by air blowing-out process technique, sulfur burning produces, then the method carrying out liquid chlorine vaporization with heating aqueous medium again, the heat energy that sulfur burning is produced by the method is applied fully, effectively reduce energy resource consumption, it is achieved the purpose of energy-conserving and environment-protective。
