Detailed description of the invention
The invention will be further described with reference to the accompanying drawings
As shown in Figure 1, a kind of iodine vapor dispenser that can add iodine online, by iodine vapor generation systems, carrier gas pre-heating system, adds iodine system and connects the pipeline of each device and valve forms online.Air compressor 25 is connected with gas bomb 24, gas bomb outlet is connected with flowmeter 26, flowmeter 26 is connected with needle valve 1, helix tube 3 one end is connected with needle valve 1, the other end is connected with triple valve 4, the other two ends of triple valve are respectively with air inlet pipe 15 with balance tracheae 5 and be connected, and what the other end of air inlet pipe 15 connected is iodine vapor generating means, and what balance the other end connection of tracheae 5 is charging system.Before system cloud gray model, air compressor 25 runs the Compressed Gas making to store certain pressure in gas bomb 24, the temperature of water-bath 19 and water-bath 20 is set to desirable value simultaneously, and when temperature reaches setting value, water-bath stops heating automatically.When system is normally run, dry compressed air carrier gas is heated to temperature required by entering helix tube 3 after needle valve 1 adjust flux, iodine pond 13 is entered inner by triple valve 4 and air inlet pipe 15, carrier gas forms radial radiation air-flow by diffusion sprayer 18, mix with the iodine vapor produced, gaseous mixture upwards flows through the annular gap between diffusion sprayer 18 and iodine pond 13 to be regulated to enter by escape pipe 21 and needle valve 22 successively after lower equal pore version 16 and upper equal pore version 14 and uses iodine system.
Figure 2 shows that the iodine pond 13 of iodine vapor generating means and the structural representation of charging system, the iodine pond 13 of iodine vapor generating means is vertical tank body, cylindrical cavity, and its welded top has air inlet pipe 15, escape pipe 21, Pressure gauge 9 and thermocouple 12.Iodine pond 13 non-integral, but be divided into upper and lower two parts, middlely to connect with snap joint 17, with for convenience detach when maintenance.Air inlet pipe 15 enters in vertical tank body by vertical tank body 13 top, and successively through upper gas averaging board 14 and lower gas averaging board 16, its end and diffusion sprayer 18 weld together, and keep leaving certain gap bottom diffusion sprayer and iodine pond 13, leave certain space to added iodine particle.Upper gas averaging board 14 and lower gas averaging board 16 are welded with iodine pond inwall by its excircle, upper gas averaging board 14 peripheral different-diameter be circumferentially uniformly distributed with several circular holes, lower gas averaging board 16 is circumferentially uniformly distributed with several circular holes, as shown in Fig. 3 (a)-(b) the different-diameter near center.Balance tracheae 5 bottom in charging system is fixed by welding in the top of loading hopper 8, in order to the pressure of inside, iodine pond during equalizing addition.Loading hopper 8 is divided into upper and lower two parts, and centre connects with snap joint 7, so that when reinforced, for convenience detach, curtails the feeding hours.Also be connected with a blast pipe at the top of loading hopper 8, blast pipe has an air bleeding valve 6, in order to get rid of gas remaining in reinforced rear charge pipe.The latter half of loading hopper 8 is connected with globe valve 10 by pipeline, and globe valve 10 is connected with charge pipe 11 afterwards, and charge pipe 11 is together with the lower weld in iodine pond 13, and the reinforced mouth of pipe should lower than diffusion sprayer 18, in order to avoid iodine particle is blocked by annular gap when adding iodine.Before the work of iodine vapor generating means, a certain amount of iodine particle need be added as the raw material producing iodine vapor in iodine pond 13 by feeding device, do not need when initially adding iodine to balance source of the gas, because loading hopper 8 and inside, iodine pond 13 are normal pressure, it is inner that iodine particle can rely on gravity to enter iodine pond, the maximum of added iodine particle should ensure that it does not highly flood diffusion sprayer 18, in order to avoid block the circular hole on diffusion sprayer.Diffusion sprayer 18 is semicircular arc, several circular holes in its surface distributed, can to make like this carrier gas by time radially, its structural representation is as shown in Fig. 4 (a)-(b).Along with the iodine vapor produced more and more is pulled away, the iodine number in iodine pond is fewer and feweri, when iodine number less to a certain extent after, the iodine vapor that carrier gas is carried can not meet by the iodine number required by iodine system, now needs in iodine pond, to add iodine by feeding device.When adding iodine, first open snap joint 7, a certain amount of iodine is added in loading hopper 8, snap joint 7 is tightened rapidly, then while triple valve 4 being switched to balance tracheae 5, ball valve 10 is opened, because inside, iodine pond 13 stops air feed, therefore it is inner that the pressure now in loading hopper 8 is greater than iodine pond, and added iodine can enter the inside in iodine pond 13 smoothly.When after reinforced end, close ball valve 10 rapidly, triple valve 4 is switched to air inlet pipe 15, then iodine vapor generator is started working again, now at charge line 11 and inner some gas remaining of loading hopper 8, opens air bleeding valve 6, gets rid of these gas.
Iodine vapor generation systems of the present invention is made up of iodine pond 13, upper gas averaging board 14, carrier gas pipe 15, lower gas averaging board 16, snap joint 17, carrier gas diffusion sprayer 18, precision pressure gauge 9, thermocouple 12, temperature controlled water bath 20, and object is the supply of iodine vapor long-time continuous stable.
The output of iodine steam is relevant with the temperature and pressure of inside, iodine pond 13, when temperature and pressure is fixed, in iodine pond 13 iodine distillation and sublimate and can reach a homeostasis process, therefore when the temperature and pressure of inside, iodine pond 13 remains unchanged, the amount of the iodine vapor produced in the internal unit time of iodine pond 13 is certain, and load volume and the iodine vapor amount of carrying exist following relation.The iodine vapor amount that initial carrier gas is carried increases with the increase of carrier gas flux, this is because the iodine vapor amount of carrying in this stage unit time carrier gas is less than the amount of the iodine vapor that iodine distillation produces in the internal unit time of iodine pond 13; After continuing to increase carrier gas flux to a certain value, the amount of the iodine vapor carried out reaches a maximum, keep stable afterwards, now continue augmented flow, the iodine vapor amount carried out also can not increase, this is because the iodine vapor amount of carrying within this carrier gas unit interval in stage is greater than the amount of the iodine vapor that iodine distillation produces in the internal unit time of iodine pond 13.Therefore, the amount of the iodine vapor that carrier gas is carried can be controlled by two kinds of methods: keep iodine pond 13 internal temperature and pressure constant, controlled the amount of the iodine vapor that carrier gas is carried by the flow controlling carrier gas, thus make the amount of the iodine vapor carried out be stabilized in desirable value; Keep carrier gas flux constant, controlled the iodine vapor amount produced by the temperature and pressure controlling inside, iodine pond 13, the iodine vapor amount carried out can be made equally to be stabilized in desirable value.Described iodine vapor generating means is an airtight structure, in plant running process, the carrier gas of heat forms radial air-flow through carrier gas pipe 15 by diffusion sprayer 18, then mix with the iodine vapor that produces in iodine pond, then mist is flowed to top, iodine pond by the annular gap between diffusion sprayer 18 and iodine pond 13, because carrier gas can reach identical temperature inner with iodine pond through preheating, therefore carrier gas can not cause disturbance to the temperature of inside, iodine pond, can maintain the homeostasis process that inside, iodine pond has been set up all the time.In the process that mist upwards flows through annular gap, first by lower gas averaging board 16, lower gas averaging board 16 is having two weeks uniform circular holes near immediate vicinity, and it is while changing mist flow process, and what also make the concentration of mist become is more even.After lower gas averaging board 16, mist continues upwards to flow, gas averaging board 14 in arrival, upper gas averaging board 14 circumferentially has the uniform circular hole of two rows close peripheral different-diameter, change the flow process of mist in order to second time, thus again make gas and vapor permeation even, upper and lower gas averaging board is set, carrier gas can be made fully to mix with iodine vapor, thus ensure the stable of outlet iodine vapor concentration.After upper gas averaging board 14, mist just flows out iodine pond 13 through escape pipe 21.At the top in iodine pond 13, the measuring point of pressure and temperature is housed, in normal course of operation, precision pressure gauge 9 and thermocouple 12 can monitor the pressure and temperature of inside, iodine pond at any time, in order to avoid large fluctuation occurs for iodine pond internal temperature and pressure, thus cause the fluctuation of iodine vapor output.Iodine pond 13 adopts the mode of heating water bath, and the advantage of the method is: accurately can control the temperature of inside, iodine pond 13 for certain certain value, not need to take Insulation in addition; By changing the temperature of water-bath flexibly, and then the temperature of inside, iodine pond 13 can be changed, controlling the output of iodine steam, with satisfied different operating mode to the demand of iodine vapor concentration.
The iodine system that adds of the present invention is made up of balance tracheae 5, air bleeding valve 6, snap joint 7, loading hopper 8, globe valve 10, feed pipe 11.For convenience of dismounting, save feed time, loading hopper 8 is by dimerous up and down, and the snap joint 7 of upper and lower two parts connects.The top of loading hopper 8 is connected with balance tracheae 5, and balance tracheae 5 is in order to provide a road balance source of the gas, and to balance the pressure of inside, iodine pond 13, the iodine added by guarantee can enter iodine pond 13 smoothly.Globe valve 10 is in normally off, in order to isolate iodine pond and to add iodine system, opening, namely closing after adding iodine when adding iodine.Air bleeding valve 6 is in normally off, opens adding after iodine process completes, and in order to discharge the gas remained in loading hopper, avoids adding next time remaining gas when iodine opens snap joint and sprays, ensure that adding iodine next time can carry out safely.Because iodine vapor is poisonous, therefore above-mentioned iodine vapor generating means and add iodine system online and be all placed in fume hood, avoids possible leakage to cause iodine vapor in the diffusion of indoor.
Carrier gas pre-heating system of the present invention is in order to heat carrier gas, because cold carrier gas enters inside, iodine pond 13, the temperature of meeting inside, disturbance iodine pond 13, thus break the homeostasis process set up inside, iodine pond 13, preheating is carried out to carrier gas, can ensure that the temperature of carrier gas is consistent with the temperature in iodine generator, thus maintain the dynamic equilibrium of inside, iodine pond 13 all the time, ensure the stable of iodine generator outlet iodine vapor concentration.Above-mentioned carrier gas preheating device is made up of needle valve 1, helix tube 3, temperature controlled water bath 19 and thermocouple 27.Needle valve 1 can regulate the flow of carrier gas in a big way, to adapt to the requirement of different operating mode.Economizer bank 13 is spiral helicine copper tube, adopts helix tube can increase the contact area of economizer bank and water, thus exchange capability of heat is strengthened; Copper tube is selected to be that exchange capability of heat is strong, corrosion-resistant because the heat transfer coefficient of copper tube is large.Thermocouple 27 for monitor carrier gas outlet temperature, with thermocouple 12 with the use of, can ensure carrier gas and iodine pond inside remain identical temperature.
Dispensing loop mainly contains air compressor 25, gas bomb 24, flowmeter 26, needle valve 1 and carrier gas preheating device and iodine vapor generating means composition.Air compressor 25 provides the air of certain pressure to gas bomb 24, and compressed air is adjusted to after required flow through needle valve 1 and enters carrier gas preheating device 2, and carrier gas is heated to required temperature and enters iodine pond 13, takes the iodine vapor of generation out of system to needing iodine.
