Description
Technical field
The utility model relates to the energy conservations in chlorine industry production.
Background technique
Status of the country in terms of chlorine gas liquefaction, liquid chlorine vaporization energy saving：
It is organized the compilation by former the Ministry of Chemical Industry《Chlor-alkali production technology》The liquid chlorine heat exchanger that one book is mentioned energy saving can disappear
Consumption 40%, unit area evaporating capacity is big, but process CIMS is complicated, and there are agenes to gather risk, needs periodically to arrange
A certain amount of liquid chlorine can be both lost in dirt, and blowdown process easily sends out safety accident.
The heat that low pressure chlorine gas liquefaction is released is supplied to liquid chlorine by refrigerant freon by certain domestic chlor-alkali plant
Vaporization uses.And a kind of new method of liquid chlorine vaporization of disclosure of the invention that number of patent application is 2013102240749.Utilize three
The cooling water generated in phosphorus chloride or phosphorus oxychloride production process is allowed to vaporize to heat chlorine.The present invention takes full advantage of energy
Source gives the present invention beneficial enlightenment, but the utilization method and its benefit to chlorine resource fail disclosure.
Summary of the invention
Purpose of utility model：
There is provided a kind of energy for making full use of chlorine gas liquefaction and gasification, for the liquid chlorine of phosphorus trichloride production and supply quality raw materials
With chlorine mixed production with use equipment.
Technical solution：
The liquid chlorine and chlorine mixed production equipment of the utility model, have the pressurized liquefied device of chlorine（With primary chlorine
Entrance, liquid chlorine outlet, extra exit A；Outer wall separately has cooling water water route, and auxiliary provides the cooling capacity that liquefaction needs）, liquid chlorine storage
Device（Liquid chlorine entrance, liquid chlorine outlet）, heat-exchange device（Can by chlorine gas liquefaction generate heat absorption and release be used as chlorine
Gasify the heat needed）, liquid chlorine gasification device（With liquid chlorine entrance, high-purity chlorine gas outlet；Outer wall separately has Water, steam circulation water route,
Auxiliary provides the heat that gasification needs）, air accumulator（With high-purity chlorine inlet, chlorine feed outlet, extra exit B）, trichlorine
Change phosphorus process units（With chlorine feed entrance）.
Liquid chlorine exports connection liquid chlorine entrance, and liquid chlorine exports connection liquid chlorine entrance, and high-purity high-purity chlorine of chlorine gas outlet connection enters
Mouthful, chlorine feed exports connection chlorine feed entrance.
Extra exit A guarantees pressure security in the pressurized liquefied device of chlorine for completely not liquefied chlorine outflow.Safety goes out
Mouth B is released for the chlorine after superpressure, guarantees pressure security in air accumulator.The equal connection of extra exit A, extra exit B is primary
Chlorine inlet into next circulation, and cannot directly enter phosphorus trichloride process units, because chlorine therein may adulterate
Air, purity do not reach requirement the purity that phosphorus trichloride synthesis needs.
The heat-exchange device can use heat-exchange medium, carry out heat absorption and two kinds of heat exchanging process of heat release, so that
Heat can store or convey after carry out heat exchange release, meet production line it is longer when heat transfer requirements.
The utility model technical process：
External compression chlorine gas source enters liquefier, is largely liquefied, and the chlorine not being liquefied on a small quantity passes through first
Gas-liquid separator separates flow away distribution platform after coming out, the part being largely liquefied enters liquid chlorine storage tank.
It needs in use, liquid chlorine storage tank outflow liquid chlorine enters superheater heating, small part passes through the second gas-liquid separator, gas
Change is partly refluxed to liquefier entrance, remaining liquefaction is partly refluxed to liquid chlorine storage tank.Major part after superheater heating passes through gas
Change device, which is gasified, finally sends to the use of phosphorus trichloride synthesizer into Chlorine Buffer Vessel for almost pure chlorine.
In the utility model, by heat exchange, fails liquefied chlorine on a small quantity or fail the liquid chlorine of vaporization on a small quantity, rely on
The heat exchange pipe less important work of respective outer wall guarantees that liquid chlorine vaporizes needs entirely.
The utility model can also connect energy saving vapourizing unit, be connected between superheater and Chlorine Buffer Vessel, energy saving vapour
Change is connected by circulation with superheater, and heating load circulation is used interchangeably, and carries out Energy Saving Control.It is preferred that the pressurized liquefied device primary chlorine of chlorine
The pressure of gas entrance is 0.5MPa or so, the chlorine gas pressure of high-purity chlorine gas outlet of liquid chlorine gasification device in 0.15 MPa or so,
The cooling capacity of the substantially equivalent liquid chlorine vaporization of heat of chlorine gas liquefaction generation in this way（Gasify the heats of needs）, can reach at this time best
Using energy source and energy-saving effect.
Not liquefied chlorine distributes platform by tail gas, sends to synthetic hydrochloric acid.
System chlorine is extracted out when leading to safety valve jumping up or system overhaul such as system pressure height, removes light chlorine through pipeline
Aspiration tower absorbs chlorine with lye.
Beneficial effect：
The utility model economy and safety benefit.
Chlorine gas liquefaction consumes cooling capacity in chlor-alkali production, and liquid chlorine vaporization needs heat, which combines the two processes
Energy is made full use of, is up to energy-saving purpose.
Applicant enterprise has 12.6 ten thousand tons/year of liquid chlorine yield（It 15.75 ton/hours, was calculated by 8000 hours）.After compression
The chlorine of 0.5Mpa or so carries out heat exchange, liquid chlorine feed liquor chlorine storage tank in liquefier and 6 DEG C of lithium bromide chiller of chilled water.It is another because
Downstream product phosphorus trichloride manufacturing technique requirent high-purity chlorine, it is therefore necessary to requirement can be only achieved by liquid chlorine vaporization, use
Hot water heating dry type gasification process route, evaporating capacity are 12 ton/hours.The two combines, and reaches following effect：
Overall process is the vaporization of liquid chlorine dry type, and no liquid chlorine accumulates in vapourizing unit（Energy-saving appliance, hot water vaporization device）.Sufficiently benefit
With energy saving vaporizer ability.After device operation, expense is saved every year（It is originally intended to the thermal energy of liquid chlorine vaporization and chlorine gas liquefaction is provided
Cooling capacity expense）About 6,000,000.
