Description
Technical field
The present invention relates to a kind of drier, particularly a kind of electrical heating gas-drying apparatus.
Background technology
In the application of various automatic industrial, compressed air is the source of the gas served many purposes, and air is by the process compressed, and contained steam is together compressed, and result in the air after compression and has relatively high atmospheric dew point.Relative humidity in general atmosphere, up to more than 65%, can inevitably be entrained with a large amount of liquid water droplets in the saturated air formed after compressed condensation, and they are basic reasons of equipment, pipeline and valve corrosion.
No matter too much moisture in compressed air, be at liquid or vapor stage, all may bring various problem to user operation, such as, cause damage to article such as the electrical equipments in container, corrode etc. ducted material.In addition on the one hand, in the application of humidity generator, as one of the important composition of carrier gas type drying system, require high to Gas reclamation drying device, dried gas to mix with its water saturation gas as original gas and produces the adjustable ambiance of relative humidity afterwards.
Existing air drying device of compressor mostly is the large-scale drying equipment that factory uses, poor to the dew point controlling of dry gas, can not fully absorb the moisture in air and reach stable outlet dew point; And distribution of gas is uneven in tower, easily there is phenomenon of stopping over.
Summary of the invention
The object of this invention is to provide a kind of electrical heating gas-drying apparatus, getting rid of the moisture in compressed air, while reducing compressed-air actuated dew point, ensure continuously dried compressed air to be sent into air accumulator.
The object of the present invention is achieved like this: a kind of electrical heating gas-drying apparatus, comprise liquid-gas separator, air blast, heater, drying chamber one and drying chamber two, described drying chamber one and drying chamber two offer the gas port one being positioned at tank body top and the gas port two being positioned at tank body lower part respectively; Described liquid-gas separator is connected with the gas port two of drying chamber two by stop valve one, pneumatic ball valve two, the gas port two of drying chamber two is also connected with the pneumatic ball valve three be connected with air; The gas port two of drying chamber one is connected to pneumatic ball valve one and pneumatic ball valve four, pneumatic ball valve one be connected the pipeline of stop valve one with pneumatic ball valve two and be connected, pneumatic ball valve four is connected with air; The gas port one of drying chamber one is connected to check valve one and check valve four, and the gas port one of drying chamber two is connected to check valve two and check valve three, and check valve one is connected with check valve two by pipeline one; Check valve four-way piping two is connected with check valve three; Between pipeline one and pipeline two, cross-over connection has coldblast magnetic valve; The air outlet of described air blast is connected with the air inlet of described heater, and the air outlet of described heater is connected with pipeline two by check valve five.
When pneumatic ball valve one and pneumatic ball valve three are opened, when pneumatic ball valve two and startup ball valve four are closed, Wet Compression air enters liquid-gas separator by surge tank, enters drying chamber one drying after removing droplet through stop valve one, pneumatic ball valve one.Air accumulator is entered through upper one-way valve one and piping filter after drying.Meanwhile, after the air of 0.35MPa is heated to 200 DEG C by heater by air blast, sends into drying chamber two top through check valve, from top to bottom drive moisture in drying chamber two out of, and through pneumatic ball valve three emptying.Be raised to 80 DEG C through 3 ~ 4h delivery temperature, complete drying chamber two hot recycling, stop heating and air blast.Then coldblast magnetic valve is opened, and makes a small amount of dry air enter drying chamber two, through 3 ~ 4h, stops coldblast, wait to be switched after making tank internal desiccant be cooled to about 50 DEG C.
To timing, first pneumatic ball valve one and pneumatic ball valve three close, and pneumatic ball valve two and pneumatic ball valve four are opened again, switch operating drying chamber, start to work/regeneration cycle process next time, ensure continuously dried compressed air to be sent into air accumulator.
Compared with prior art, the invention has the beneficial effects as follows: when a tank carries out compressed air drying, another tank then carries out the regenerative process that moisture in tank is got rid of in electrical heating, and the work of two tanks and regenerative process exchange-column shift, guarantee the continuity of air feed; Adopt the modular, pneumatically powered ball valve of 4 cover to realize gas circuit to switch, gas flow resistance can not only be reduced, reduce the pressure loss, and control gas circuit can use oil lubrication, improves the reliability of control valve.
