Technical field
The present invention relates to oil gas absorption regeneration technical field, more particularly to a kind of absorption regeneration dress with solid-liquid phase change material
Put and adsorpting regenerating process.
Background technology
The VOC such as oil gas gases typically make emission compliance by processes such as absorption, during absorption frequently with specific surface area very
Big activated carbon, because adsorption process is an exothermic process, and after charcoal absorption oil gas, its burning-point may be reduced to 100 DEG C
Left and right, therefore the Standard such as GB 50759-2012 controls within 65 DEG C adsorption temp, if adsorption process temperature control is not
It is good, huge potential safety hazard will be brought.
For the problem of adsorption temp control, had before oil gas enters acticarbon, first by oil gas condensation, make oil
A large amount of coercibility material phase transformations in gas, reduce the gas concentration for entering acticarbon, are also lowered into acticarbon
Temperature technique, referred to as condensation+absorbing process, relative to absorbing process, the efficiency that it intercepts oil gas is relatively for condensation process
It is low, energy consumption undoubtedly increased using such technique.
Also have by increasing cooling coil in absorbent charcoal adsorption tank to take away the design of heat of adsorption, such as patent
CN201020252215, increased cooling coil in adsorption tanks, and adsorption tanks, band are recycled into by the cold gasoline for condensing out
Walk heat of adsorption.This can undoubtedly increase investment, increase system complexity.
It is general that regenerating active carbon is made using vacuum regeneration technique after charcoal absorption oil gas, during regeneration, due to absorption oil gas
Volatilization adsorbent is lowered the temperature, temperature reduction cause oil gas difficult desorption.More seriously, for some high-melting-point things such as benzene
Matter, due to evaporation endothermic during desorption, may make temperature be reduced to the freezing point of the high-melting-point substances such as benzene, and adsorbate is in activated carbon capillary
Interior crystallization, causes the destruction of activated carbon capillary, activated carbon " poisoning " is failed, so, during desorption, it is often necessary to introduce heating
Air or nitrogen, to avoid the crystallization of adsorbate, enable regeneration to smoothly complete, and such as patent CN201110090661 is by introducing 60
~80 DEG C of nitrogen makes desorption thoroughly, and this undoubtedly increases energy consumption, also increases operating cost.

Bottom, after balance purging valve is opened 1~3 minute, vavuum pump stops pumping, while the second vacuum valve is closed, balances blow down valve
Door continues to open tonifying Qi, makes that the pressure in the second adsorption tanks for exhaust vacuum gradually recovers to close after normal pressure or left and right adsorption tanks are cut
Closed when changing, to treat the alternate run of next time and the first adsorption tanks；
Step 3：During high concentration desorption gas after vavuum pump is vacuumized is delivered to follow up device.
15. a kind of adsorpting regenerating process with solid-liquid phase change material, it is characterised in that comprise the following steps：
Step A：Pending oil gas enters through oil and gas import, and oil gas enters the second adsorption tanks through the second oil-feed air valve, and the
Adsorbed by the second adsorbent in two adsorption tanks and intercepted, solid-liquid phase change material absorbs a large amount of heats of adsorption by finned tube makes solid-liquid phase change
Material becomes liquid by solid, and stabilization adsorption temp, remaining cleaning tail gas goes out after being heated up by remaining a small amount of heat of adsorption through second
Oil gas valve enters air, and while the second adsorption tanks absorption oil gas, the first adsorption tanks are in regeneration, the alternating for regenerating and adsorbing
Between be 10~20 minutes；
Step B：Recovery time is set as 20 minutes, when the first adsorption tanks start regeneration, the first vacuum break valve, while vacuum
Pump startup, the negative pressure that vavuum pump is produced makes adsorbate evaporate and be discharged by vavuum pump, while adsorbate absorbs solid-liquid from finned tube
The heat of phase change material, makes solid-liquid phase change material gradually become solid by liquid, and temperature during stabilization desorption, the time to be regenerated reaches
When reaching 1~15KPa after by 10~15 minutes or according to the pressure in the first adsorption tanks for being regenerated, blow down valve is balanced
Door is opened, and the first adsorption tanks are filled into the heated clean tail gas from the discharge of the second adsorption tanks, makes regenerating active carbon more thorough
Bottom, after balance purging valve is opened 1~3 minute, vavuum pump stops pumping, while the first vacuum valve is closed, balances blow down valve
Door continues to open tonifying Qi, makes that the pressure in the first adsorption tanks for exhaust vacuum gradually recovers to close after normal pressure or left and right adsorption tanks are cut
Closed when changing, to treat the alternate run of next time and the second adsorption tanks；
Step C：During high concentration desorption gas after vavuum pump is vacuumized is delivered to follow up device.
A kind of 16. adsorpting regenerating process with solid-liquid phase change material according to claims 14 or 15, it is characterised in that
In step 1 or step A, in the first adsorbent or the second adsorbent exotherm, oil gas is intercepted, and remaining clean gas are taken away
Partial adsorbates heat simultaneously discharges the first adsorption tanks or the second adsorption tanks, and the heat of adsorption for being left part is acted on by the convection heat transfer' heat-transfer by convection of gas
The accumulation of energy material being filled in hollow the first heat exchanger tube or the second heat exchanger tube, accumulation of energy thing are passed to the conductive force of adsorbent
Matter heat-absorbing liquefaction, accumulation of energy material absorbs substantial amounts of heat in the case where temperature is basically unchanged when liquefying, will not overtemperature when making absorption.
A kind of 17. adsorpting regenerating process with solid-liquid phase change material according to claim 16, it is characterised in that the storage
Energy material uses calcium chloride hexahydrate, hypo, sodium acetate trihydrate, disodium hydrogen phosphate, acetic acid or paraxylene,
Its crystalline temperature is higher than the environment temperature for being used 3~20 DEG C.
A kind of 18. adsorpting regenerating process with solid-liquid phase change material according to claims 14 or 15, it is characterised in that
In step 2 or step B, absorption regeneration makes the first adsorbent or the second adsorbent reactivation after 20 minutes using vacuum desorption, regeneration
When, temperature is gradually decrease to accumulation of energy substance crystallization point, and accumulation of energy material starts phase transformation and releases substantial amounts of heat, makes regeneration be more easy to carry out,
Adsorbate is set to crystallize at low temperature simultaneously, the microcellular structure of the first adsorbent of protection or the second adsorbent；In regeneration most
Stage afterwards, vavuum pump makes the first adsorption tanks or the second absorption pressure inside the tank be reduced to 1~15KPa, slow to open first and go out oil gas
Valve or the second fuel-displaced air valve or balance purging valve, fresh air purging adsorbent and the accumulation of energy thing of introducing portion low temperature
Matter, it is ensured that regeneration is complete and ensures the whole phase transformations crystallization of accumulation of energy material.
A kind of 19. adsorpting regenerating process with solid-liquid phase change material according to claims 14 or 15, it is characterised in that
In step 2 or step B, the vavuum pump is used to control oil gas flow by Frequency Converter Control, and will not mistake when starting it
Carry.
