Abstract
The incomplete method of liquid chlorine vaporization is avoided using T-T control methods the invention discloses a kind of, when being vaporized under a certain pressure using liquid, its liquid phase temperature remains unchanged principle, control discharge nozzle implication temperature keeps certain difference with temperature is fed out, that is Outlet Gas Temperature t2 is greater than inlet feed temperature t1 in a certain range, then can guarantee all vaporizations of discharging at this temperature；Vaporizer system output gas temperature t2 is greater than vaporizer system feeding temperature t1 within the scope of 15 ± 5 DEG C；When t2-t1 < 15 DEG C, control valve opening is turned down, reduces liquid chlorine inlet amount；When t2-t1 > 15 DEG C, big control valve opening is opened, increases liquid chlorine inlet amount.The present invention avoids liquid chlorine vaporization incomplete using T-T control methods, is reliably realized with unidirectional linearity relationship and avoids the incomplete problem of liquid chlorine vaporization, method is simple and easy, and cost is relatively low.
Description
Technical field
The incomplete method of liquid chlorine vaporization is avoided using T-T control methods the present invention relates to a kind of.
Background technique
Chlorine is a kind of important industrial chemicals, can carry out substitution reaction with organic matter and inorganic matter and addition reaction is raw
At a variety of chlorides.Be widely used in produce plastics (such as PVP), synthetic fibers, dyestuff, pesticide, disinfectant, bleaching agent solvent with
And various chlorides, China produce every year and using chlorine up to more than 3,000 ten thousand tons.For the ease of storing and transporting, existing chlorine
Product largely needs to carry out liquefaction processing, re-vaporizes and uses when needing.The reaction occurred when chlorine is as raw material is largely
Chlorination reaction.Chloridization process belongs to high-risk technique, raw material chlorine used in chloridization process be largely by liquid chlorine vaporization come
Chlorine, if when liquid chlorine vaporization control it is improper cause in chlorine carry secretly liquid chlorine enter reaction system, will be brought to chlorination reaction
Very big uncertainty and security risk, therefore it is particularly important to ensure that liquid chlorine completely vaporizes.Existing liquid chlorine vaporization technique is in chlorine
When vaporizing quality high request, all it was heating or gas-liquid separation, and prevented entrainment liquid chlorine in chlorine from entering reaction process.It is this
Method had both increased installations and facilities investment, also waste of energy.
Chinese patent application CN107065982A discloses the automatic control system and control of a kind of low temperature ethylene vaporizer
Method provides one kind in heat exchanger w-1 and heats the heat transfer medium vaporization with steam, using vaporized heat transfer medium in heat exchanger
Liquid ethylene is vaporized in w-2, ethylene gas a part of output is excessively heated into overheat by heat transfer medium by heat exchanger w-3
Gas controls cold and hot two bursts of ethylene gas mixed proportions using three-way control valve and reaches control vaporization dress output ethylene gas body temperature
Degree.When system temperature, pressure parameter are more than setting value to liquid ethylene or heating steam interlocking cutting.
Chinese patent application CN201180903Y discloses a kind of automation control liquid chlorine vaporization system, and vaporizer is by center
Cylinder and coil pipe composition, are a kind of wet type carburetion systems, need the timely sewage treatment accumulation liquid chlorine of agene containing high concentration and chlorine
Gas.The hot water temperature in steam feed flow control hot water storgae.
Chinese patent application CN205781984U discloses a kind of PLC automatic control, and tubular type vapourizing unit, steel cylinder heat preservation are certainly
Dynamic heating and vaporizing device uses side by side, including weighing device, steel cylinder attemperator, and carburetor arrangement, 2 surge tanks, chlorine are anti-
Answer container and chlorine absorption processing unit.
Not about the incomplete control method of the how anti-devaporation of vaporizer itself or function in the above patents state
It is required that and description.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the defect of the prior art, provides and a kind of avoided using T-T control methods
The incomplete method of liquid chlorine vaporization.
In order to solve the above-mentioned technical problems, the present invention provides the following technical solutions:
The present invention disclose it is a kind of avoid the incomplete method of liquid chlorine vaporization using T-T control methods, using liquid certain
When vaporizing under pressure, liquid phase temperature remains unchanged principle, and control discharge nozzle implication temperature keeps one with temperature is fed out
Determine difference, i.e. Outlet Gas Temperature t2 is greater than inlet feed temperature t1 in a certain range, then can guarantee that discharging is all at this temperature
Vaporization.
Further, vaporizer system output gas temperature t2 is greater than vaporizer system feeding temperature t1 in 15 ± 5 DEG C of models
In enclosing.
Further, when t2-t1 < 15 DEG C, control valve opening is turned down, reduces liquid chlorine inlet amount；When t2-t1 > 15 DEG C,
Big control valve opening is opened, liquid chlorine inlet amount is increased.
The beneficial effects obtained by the present invention are as follows being:
The present invention avoids liquid chlorine vaporization incomplete using T-T control methods, is reliably realized with unidirectional linearity relationship and avoids liquid chlorine
Incomplete problem is vaporized, method is simple and easy, and cost is relatively low.
Detailed description of the invention
Attached drawing is used to provide further understanding of the present invention, and constitutes part of specification, with reality of the invention
It applies example to be used to explain the present invention together, not be construed as limiting the invention.In the accompanying drawings:
Fig. 1 is structural schematic diagram of the invention.
Specific embodiment
Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, it should be understood that preferred reality described herein
Apply example only for the purpose of illustrating and explaining the present invention and is not intended to limit the present invention.
As shown in Figure 1, liquid phase temperature remains unchanged principle when being vaporized under a certain pressure using liquid, control out
Expects pipe implication temperature keeps certain difference with temperature is fed out, i.e. Outlet Gas Temperature t2 is greater than inlet feed temperature t1 one
Determine range, then can guarantee all vaporizations of discharging at this temperature；Process require that vaporizer system output gas temperature t2 is greater than vapour
Change device system feeding temperature t1 within the scope of 15 ± 5 DEG C.When t2-t1 < 15 DEG C, control valve opening is turned down, reduces liquid chlorine charging
Amount；When t2-t1 > 15 DEG C, big control valve opening is opened, increases liquid chlorine inlet amount.
Finally, it should be noted that the foregoing is only a preferred embodiment of the present invention, it is not intended to restrict the invention,
Although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art, still may be used
To modify the technical solutions described in the foregoing embodiments or equivalent replacement of some of the technical features.
All within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in of the invention
