The present invention provides a kind of dry method resolution systems of exhaust gas, with adsorption-desorption tank and it is set to its internal adsorbent material, and it is embedded in the coil pipe among adsorbent material in advance, the coil pipe has the multiple action of conveying refrigerant or heating agent, from the cooling of adsorbent material inside or heating adsorbent material.The present invention using when coil pipe in be passed through hot steam, from the inside of adsorbent material heating adsorbent material fast resolving come out.When being passed through refrigerant in coils, the temperature of adsorbent material can be reduced to -10-30 DEG C, and adsorption effect is more preferable.
Description
Technical field
The present invention relates to a kind of adsorption-desorption technologies of exhaust gas.
Background technique
Adsorption-desorption device is commonly used for carrying out preliminary treatment to exhaust gas, and adsorption-desorption device generally has tank body, in tank
Internal portion has adsorbent material, and when exhaust gas enters tank body, adsorbent material can adsorb the portion in exhaust gas.Work as adsorption material
After material adsorbs more exhaust gas, desorbed, desorption is that steam or nitrogen are passed through into tank body, so that in adsorbent material
Exhaust gas releases, and is able to carry out next step adsorption-desorption circulation.But the heat in common adsorption-desorption tank is not uniform enough,
The adsorption capacity of filler is not applied adequately, and the desorption of exhaust gas is also not thorough when desorption.
Summary of the invention
Goal of the invention:
There is provided one kind can be improved exhaust gas adsorption-desorption speed, not increase the dry of the exhaust gas of adsorbent material and stripping liquid secondary pollution
Method parses technique and its system.
Technical solution:
Exhaust gas dry method resolution system of the invention with adsorption-desorption tank and is set to its internal adsorbent material, also has
The coil pipe being embedded among adsorbent material in advance (i.e. coil pipe is adsorbed material package or portion envelops wherein).The import of coil pipe goes out
Mouth is respectively provided with the wall surface for being placed on adsorption-desorption tank.
The coil pipe has the multiple action of conveying refrigerant or heating agent, inhales from adsorbent material inside supplement heat rejecter or heating
Enclosure material.
Import, the outlet of coil pipe are preferably each provided at bottom, corresponding valve are just also mounted at device bottom, convenient for inspection
It repairs.And abhiseca is preferably in paraboloid, inverts downlink after gas overshoot.The condensation water flowed out from bottom is to utilize siphon principle
Discharge, without providing suction power.
The entrance of coil pipe is provided with Self controlling valve, and temperature sensor, Self controlling valve and temperature are provided in adsorption-desorption tank
Induction controller is connected between degree sensor, temperature in tank can be sent to induction controller, induction control by temperature sensor
Device processed can control the opening degree of Self controlling valve according to temperature data.When temperature increases or reduces, the folding of Self controlling valve
Degree increases, and guarantees in coil pipe that perhaps flow rate of heat medium increases so that adsorbent material fast cooling or being rapidly heated for the refrigerant that enters.
When temperature is basicly stable, illustrate to reach thermal balance, the opening degree of Self controlling valve remains unchanged, and guarantees the refrigerant entered in coil pipe
Or flow rate of heat medium is basically unchanged, so that adsorbent material temperature substantially constant.
Coil pipe by internal layer to outer layer caliber from large to small, the heat that can be exchanged of inside is also most, in this way with guarantee
The balance of heat exchange, avoids centre from overheating in tank body, guarantees that each regional temperature is identical in pipe as far as possible.It is preferred that on coil pipe wall surface
Offer numerous diameters less than 1mm micropore and control micropore folding unidirectional micropore valve (such as by setting electromagnetism
Sensing valve and its control circuit, energizing magnetic closure, are unidirectionally opened to adsorbent material direction when power-off).When needed,
Unidirectional micropore valve is opened, it is directly fast convenient for the fluid of misty cooling or the fluid of heating is discharged outward from coil pipe
Fast dispersing contact adsorbent material and exhaust gas more rapidly cool down adsorbent material and increase its adsorption capacity, or more rapidly heating is inhaled
Enclosure material increases its desorption ability.When not needing or in which fluid is not suitable for opening unidirectional micropore valve, remain closed, wall surface
Wherein fluid gives adsorbent material negative impact.
There is other desorption gas (steam or nitrogen) entrance and stripping liquid to export, the solution on the outer wall of adsorption-desorption tank
The flows outside of air-breathing body and its stripping liquid in coil pipe.
Vacuum evacuation device can also be connected on adsorption-desorption tank.
Absorption parsing processing step is as follows:
1) adsorption-desorption tank is passed through hot steam or hot water in coil pipe when desorbing exhaust gas, heats and adsorbs from the inside of adsorbent material
Material, so that the substance fast resolving of absorption comes out；
2) after being parsed, it is passed through refrigerant in coils, it is from the cooling adsorbent material in the inside of adsorbent material to room temperature or lower
Temperature so that adsorbent material be quickly cooled down, convenient for rapidly enter subsequent cycle absorption exhaust gas；
3) in the absorption phase of adsorption-desorption tank, it can also be passed through refrigerant in coils, so that the temperature of adsorbent material reduces, increase
Strong adsorption capacity, quickly export absorption heat (such as summer temperature it is higher when so that the temperature fast cooling of adsorbent material
To -10 to 10 DEG C, or it is down to 10-25 DEG C (guaranteeing absorption and energy saving double effects), adsorption effect is more preferable, adsorbs safer).
It is passed through refrigerant or heating agent inside coil pipe, (for example steaming can be passed through in conjunction with desorption mode conventional in adsorption-desorption tank
Vapour desorption mode perhaps nitrogen desorption mode or vacuumize desorption mode), from adsorbent material outwardly and inwardly respectively into
Row cooling absorption or heating desorption, so that absorption or desorption progress faster, while more exhaust gas can be adsorbed or can be made
It desorbs more thorough.So that the present invention can be improved the absorption and desorption working efficiency several times of adsorption-desorption tank or more.
In conjunction with the case where vacuum analysis, heating agent, while vacuum analysis are passed through inside coil pipe, it is ensured that resolving absorption
Filler temperature will not decline, and be conducive to the parsing and abjection of higher boiling goods and materials, be conducive to save parsing energy consumption, be conducive to improve solution
The safety of analysis.
The utility model has the advantages that
Coil pipe of the invention is built in adsorbent material, small in size, mobile convenient for skid.And hidden setting, avoid competition quotient
Business secret is known easily in family.When not being passed through heating agent or refrigerant in coil pipe, which can be used as common device and carries out
Absorption or desorption operation；When being passed through heating agent or refrigerant in coil pipe, heats or cool down simultaneously from the interior outside of adsorbent material, adsorption material
Material heating or cooling rate are fast, and absorption or desorption rate are fast, and equipment handles the capability improving one of exhaust gas again to four times.And coil pipe
In heating agent or refrigerant do not contacted directly with adsorbent material, can be easily separated, will not pollute adsorbent material make its " poisoning " reduce inhale
Attached or desorption ability, and the waste liquid desorbed is easy to carry out post-processing.
