Abstract
The present invention provides a kind of multi-stage absorption stripping apparatus of exhaust gas, successively there are main adsorption tanks, knockout drum, adsorption tanks A, adsorption tanks B, adsorption tanks C, three kinds of adsorption tanks adsorb different exhaust gas constituents respectively, the waste liquid obtained after the adsorption tanks C desorption of the equipment can become the very high fuel of fuel value, and the purified gas of discharge is completely environmentally friendly.
Description
Technical field
The present invention relates to a kind of processing units of exhaust gas.
Background technique
Exhaust gas can be usually collected using adsorbent equipment, and then parsing obtains high-concentration waste gas, then do depth again
Purified treatment.
Adsorbent equipment can be that multi-stage absorption is reduced and discharged convenient for improving adsorbance.But common multi-stage absorption lacks
It is designed respectively for the stepwise adsorption of different exhaust gas kinds, the gas of absorption is caused to mix, also need to carry out complexity after desorption
Isolation of purified process.
Summary of the invention
Goal of the invention:
A kind of absorption heterogeneity gas respectively is provided, the absorption duration of each adsorption tanks is automatically adjusted, obtains the useless of high fuel value
The multi-stage absorption stripping apparatus of gas.
Technical solution:
The present invention uses multi-stage absorption desorption apparatus and its process route.
This equipment flows through route by waste exhaust gases, and successively having main adsorption tanks, (or air collector collects the useless of higher concentration
Gas, or be pretreatment tank), (exhaust gas and waste liquid initial gross separation avoid waste liquid from infiltrating the filler below in adsorption tanks to knockout drum
Reduce its adsorb exhaust gas ability), adsorption tanks A, adsorption tanks B, adsorption tanks C.There is different adsorption stuffings in three kinds of adsorption tanks,
Different waste exhaust gases are adsorbed respectively.
(number of certain exhaust gas concentration after absorption is measured with specific gas concentration detector in exhaust gas between three kinds of adsorption tanks
According to using the absorption duration of each adsorption tanks of Self controlling valve (or PLC control valve) control).Detector is chain with Self controlling valve,
I.e. according to the concentration of detector test, the folding of Self controlling valve is controlled.
Air collector uses liquid absorption exhaust gas, for example absorbs light oil using heavy oil.Main adsorption tanks can also have cooler
Part increases adsorption function to cool down.
Adsorption stuffing in three kinds of adsorption tanks can adsorb or absorb gas componant different in exhaust gas.
Preferably, successively there is hydrophilic filler, reactivity to fill out for adsorption tanks A, adsorption tanks B, the adsorption stuffing in adsorption tanks C
Material, organophilic material or hydrophobic filler, the gas that absorbs water and water-soluble exhaust gas constituents respectively, can chemically react,
Most of organic molecule.
Hydrophilic filler, clay etc., adsorption dewatering are preset in adsorption tanks A.
Chemical reactivity filler is preset in adsorption tanks B, it can be with part inorganic molecule or small part small organic molecule
It is chemically reacted, becomes substantially harmless small gas.Such as oxygenolysis organic substance, become carbon dioxide and water.Or
With the substance that absorption carbon dioxide (or sulfur dioxide, sulfur trioxide) and water are chemically reacted, such as quick lime, raw stone
Ash water suction, which becomes calcium hydroxide and reabsorbs carbon dioxide, to be become calcium carbonate (or sulfur dioxide absorption or sulfur trioxide becomes sulfurous
Sour calcium or calcium sulfate), remove carbon elimination or element sulphur.Or using the adsorbent material that can be desorbed, to reuse.It is dropped after absorption
Low gas pressure reduces container pressure, increases safety；There is condensation facility in the tank body of adsorption tanks B simultaneously, guarantee will be chemical
The heat cooling that reaction generates is further ensured that air pressure reduces and increases security reliability, otherwise useless containing oil gas for adsorbing
Gas is than relatively hazardous.
Preset synthetic organic polymers in adsorption tanks C, such as fusion-jetting polypropylene filler, and only physical absorption,
It is not susceptible to chemically react, to solve adsorption desorption.
Preferably, there are also desulfurization (sulfur dioxide, hydrogen sulfide) fillers in adsorption tanks A or adsorption tanks B, or there are also deoxidations to inhale
Enclosure material (oxygen absorbent), so that into there was only organic substance in the exhaust gas of adsorption tanks C substantially.Adsorption tanks C has purified gas (nitrogen
Based on) evacuation port.After three kinds of adsorption tanks, adsorption tanks C desorption obtains desorption gas or liquid, so that light hydrocarbon, heavy hydrocarbons
Adsorption-desorption recycles respectively, wherein almost without moisture, carbon dioxide, sulfur dioxide, hydrogen sulfide, nitrogen, recycling compression
It is made into the higher fuel of fuel value, and the feature of environmental protection is fine.
The utility model has the advantages that
Multi-stage absorption stripping apparatus of the invention can centralized collection low concentration gas gas source, then focus on, can distinguish
Heterogeneity gas therein is adsorbed, does post-processing respectively, with strong points, high treating effect.Automatically adjust each adsorption tanks
Duration is adsorbed, not only improves adsorption efficiency, but also reduce manually-operated randomness；It is obtained after the adsorption tanks C desorption of the equipment useless
Liquid can become the very high fuel of fuel value, and the purified gas of discharge is completely environmentally friendly, obtains Gao Ran while can reducing discharge
The fuel of burning value, environmental protection and economy, utilization of resources.
