Abstract
A kind of long-time iodine vapor feedway of the invention is related to CW chemical oxygen-iodine laser device gas supply technology.The main body of device is divided into two parts, and one is electrically heated iodine vapor storage tank, secondly for the combustion chamber of two kinds of gas burning.Solid-state iodine is heated to the liquid iodophor of certain temperature by electrically heated iodine vapor storage tank, and the iodine vapor with certain saturated vapor pressure is formed on liquid level.Carbon monoxide is in combustion chamber and oxygen provides the confined space of burning and the high temperature and high pressure gas generated enters in iodine vapor storage tank after diluent gas adjusts temperature.The carbon dioxide gas of high temperature forms bubble after entering in the liquid phase of iodine vapor storage tank, and transferring thermal energy to liquid iodophor makes iodine evaporation become iodine vapor, and the iodine vapor of certain density is just contained in bubble.During bubble constantly rises in the liquid phase, this mass-and heat-transfer phenomenon constantly occurs until reaching balance.It is entered from outflow in liquid phase and flows through supply air line after gas phase and enter laser bodies.
Description
Technical field
The present invention is related with oxygen iodine chemical laser material supply.
Technical background:
Iodine vapor is one of the material of CW chemical oxygen-iodine laser device indispensability, and the method generated determines iodine vapor stream
Stability, volume and the duration of amount.The method of generation is mainly physical evaporation method, also there is chemical method.
Physical evaporation method is that solid-state iodine high-temperature heating is become liquid, controls liquid surface iodine by adjusting iodine solution temperature
The saturated vapor pressure of steam, after the vent valve of closed container is opened, iodine vapor, which can flow out, to be entered in steam line.Tool
Body is embodied as being placed on iodine crystal in the heatable stainless cylinder of steel body of vacuum tightness, have on tank body thermometric, survey pressure, pneumatic operated valve and
The attachmentes such as temperature control.Heating device is generally stainless steel heating tube, is realized by temperature measuring equipment and temperature control equipment to tank
The heating and temperature control of internal material.It is that pneumatic operated valve is opened when the intracorporal iodine vapor of tank reaches setting value, iodine vapor outflow enters
Into steam line.
The shortcomings that iodine vapor feedway of such electric heating evaporation be iodine vapor be during supply gradually under
Drop, it is gradually reduced so as to cause iodine vapor flow.Its reason is that stainless steel heating tube is placed in iodine solution body and conducts effect
Rate is slower, is unable to satisfy the demand that iodine solution body persistently evaporates.
Summary of the invention
Present invention aims at provide a kind of iodine vapor flow confession of long-time stable for CW chemical oxygen-iodine laser device
To device, the long-time steady operation of laser can satisfy.
In order to achieve the object of the present invention, specific technical solution is:
Long-time iodine vapor feedway mainly includes two parts, and one is that fluid reservoir, that is, iodine of electrically heated material iodine steams
Gas storage tank, secondly the characteristics of being the combustion chamber of two kinds of gas burning, corresponding to CW chemical oxygen-iodine laser device, both gases
It should be carbon monoxide and oxygen, wherein carbon monoxide is excessive.Iodine vapor storage tank uses the electricity with temperature control feedback device to add
Hot systems, slow heating makes iodine solution body and iodine vapor in storage tank be in the state of constant temperature and pressure after heating reaches set temperature.
The effect of combustion chamber is that oxidant gas and reducing agent gas is made to burn in its closed system, the high temperature that combustion reaction generates
High pressure gas outflow enters in iodine vapor storage tank after diluent gas adjusts temperature.High-temperature gas passes through gas in air accumulator
Distributor forms uniform bubble.Mass-and heat-transfer is completed with the iodine of liquid phase during bubble rises in liquid, in bubble
It forms the iodine vapor of saturated vapor pressure and finally flows out.
Solid-state iodine is heated to the liquid iodophor of certain temperature, and the shape on liquid level by the electrically heated iodine vapor storage tank of the present invention
At the iodine vapor with certain saturated vapor pressure.Combustion chamber for carbon monoxide and oxygen provides the confined space of burning and generates
High temperature and high pressure gas enters in iodine vapor storage tank after diluent gas adjusts temperature.The carbon dioxide gas of high temperature enters iodine
Bubble is formed after in the liquid phase of steam storage tank, transferring thermal energy to liquid iodophor makes iodine evaporation become iodine vapor, just contains in bubble
The iodine vapor of certain density.During bubble constantly rises in the liquid phase, this mass-and heat-transfer phenomenon constantly occurs until reaching
To balance.It is entered from outflow in liquid phase and flows through supply air line after gas phase and enter laser bodies.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of long-time iodine flow feedway of the invention.
Specific embodiment
As shown in Figure 1, cavity 2 and 10 tank body of fluid reservoir are respectively the fluid reservoir of combustion chamber and material iodine.Combustion chamber has not
Rust steel is made and can not have gas leak phenomenon in hyperbar.The periphery of combustion chamber is the air inlet pipeline 2 of oxygen and carbon monoxide
With 3.The spark plug 4 of igniting is used in outer wall of combustion chamber connection.Pipeline 5 is used to be added the diluent gas of regulating gas temperature such as
Helium or nitrogen etc..Helium mix of the carbon dioxide gas of high temperature after the outflow of combustion chamber with low temperature, it is pneumatic to flow through first
Valve 6 enters in gas distributor 9.Connecting line between first pneumatic operated valve 6 and gas distributor is used to be controlled with temperature
Power supply 7 and heating tape 8 heat, keep its temperature identical or slightly higher as the intracorporal equilibrium temperature of tank.10 tank body of fluid reservoir is same
Carrying out preheating to tank body using power supply 7 and heating tape 8 makes the internal material iodine solid installed become liquid iodophor.Component 11 and 12
Respectively thermocouple and pressure sensor are for monitoring the pressure of liquid iodophor temperature and iodine vapor in tank body.Second pneumatic operated valve 13 is beaten
The iodine vapor outflow tank body of tank body enters pipeline 14 when opening, and enters eventually into laser bodies.
