Abstract
The utility model discloses a drying device, which is used for purifying gas. The utility model is suitable for various gases such as hydrogen, air, nitrogen, oxygen, argon, etc. The utility model provides a hydrogen drying process on the basis of the combination of vapor heating and vacuum pumping by using a water ejector and also provides the structure of the drying device for the process. The drying device is provided with an outer jacket and is filled with silica gel inside, etc. The hydrogen drying device designed according to the process and the structure of the drying device has the advantages of simple device and convenient operation, no electric spark for generating the explosion of the hydrogen, good safety, and no hydrogen consumption during regeneration and is suitable for departments such as electric force departments, chemical industry departments, metallurgy departments, construction material departments required definite hydrogen moisture content.
Description
The invention is the drying installation that a kind of Purge gas is used, it adopts silica gel that gas is carried out drying treatment, with steam moisture eliminator is heated when silica gel need be regenerated, and vacuumizes with water-jet exhauster, two moisture eliminators switch use, reach the purpose of dry gas according to this.
The method of removing moisture in the gas is a lot, adsorption dry be use more a kind of.Moisture eliminator has more than two usually in this class device or equipment, and they regularly switch; Adsorb satisfied moisture eliminator and usually adopted hot regenerated method, and to use more be electrically heated.When such device is used for dry hydrogen, the explosion-proof problem of the sealing problem of equipment and electrically heated part is to cause to close important thing, because the leakage of hydrogen will cause serious unsafe factor, an electric heating element and lead portion then are the immediate causes that sets off an explosion.The common in addition heat regeneration that has needs other dry gas or self hydrogen, will consume self hydrogen when not possessing dry source of the gas or not allowing to use other source of the gas.
The purpose of the invention provides a kind of hydrogen drying unit, it adopts the steam heating moisture eliminator, water-jet exhauster vacuumizes the satisfied moisture eliminator of absorption of regenerating, so just overcome that ordinary hydrogen air dry appliance arrangement is numerous and diverse, operation inconvenience and unsafe shortcoming, also solved the problem of wasting self hydrogen.
Accompanying drawing 1 is the general flow chart that the invention is adopted.
This flow process is by air water separator 1, moisture eliminator 2 and 3, and water-jet exhauster 4, air water shield retaining 5, and major equipments such as several valves and trap are formed.All load silica gel in two moisture eliminators.
This hydrogen drying unit adopts flow process shown in Figure 1, and it mainly comprises the regenerative process of hydrogen desiccation process and moisture eliminator.
To the hydrogen desiccation process, raw hydrogen enters moisture eliminator 2 after air water separator 1 separates oversaturated water, and the silica gel adsorption that the moisture in the gas is dried in the device is fallen, and gets rid of the product hydrogen bleeder of moisture.
For the regenerative process of moisture eliminator, when moisture eliminator 2 work, can regenerate to moisture eliminator 3.Steam is fed the chuck internal heating moisture eliminator 3 of moisture eliminator 3, and condensed water is discharged by trap.The water intaking valve of injector 4 of meanwhile fetching boiling water makes and keeps vacuum in the moisture eliminator 3, and the water intaking valve of steam off admission valve and water-jet exhauster after a few hours stops heating and finds time, and water coolant is fed the chuck internal cooling moisture eliminator 3 of moisture eliminator 3.Water and gas that water-jet exhauster is discharged enter air water shield retaining 5, and water is discharged by the shield retaining bottom, and gas causes outdoor emptying by shield retaining top.
When moisture eliminator 3 be cooled to normal temperature or during when moisture eliminator 2 operational failures two moisture eliminators changeable.
Accompanying drawing 2 is dryer configuration figure of the invention.
Moisture eliminator is a steel welding container, filling silica gel 8 in the device, and raw hydrogen is entered by upper interface 6, and product hydrogen is discharged by bottom interface 10.The interface 7 on chuck 13 tops advances steam or water coolant, the interface 9 discharging condensed water of chuck 13 bottoms; Another interface 11 on chuck 13 tops is adorned a valve, the noncondensing gas when heating to get rid of in the chuck.The extraction pipe 12 that a root bottom part is shut is inserted at the center of moisture eliminator, opens aperture on the tube wall, and the mouth of pipe is connected with water-jet exhauster, has so just solved the suction steam problem of can not arranging of taking off that causes because of tower height; The same silica gel of also packing in the pipe is to overcome because of inserting the air-flow short circuit problem that extraction pipe that tube wall has aperture causes in the moisture eliminator.
It is simple that the hydrogen drying unit that the invention proposed and existing device are compared its equipment, and volume is little, and is easy and simple to handle; Because therefore its not electricity consumption does not exist the electrical spark that causes hydrogen explosion, security is good; Because it is a vacuum regeneration, therefore do not consume hydrogen, reduced energy consumption.This hydrogen drying unit is applicable to departments such as electric power, chemical industry, metallurgy, building materials that the hydrogen water capacity is had certain requirements.
The hydrogen drying unit that the invention proposed also is applicable to the drying of multiple gases such as air, nitrogen, oxygen, argon gas.
According to technical process that the invention proposed and dryer configuration and the significant parameter of the hydrogen drying unit that designs sees Table 1.
