The work step principle for the organic exhaust gas adsorption desorption catalytic purifier that the present embodiment is related to is：
First stage：Exhaust gas enters gas inlet pipeline 1, and the purifier 31 of respective numbers is selected according to exhaust gas concentration,
The valve body of other spare purifiers 31 is turned off, and purifier 31 opens purification work, and the purification used at this time is set
Standby fifth hole 3117 and the 6th through-hole 3118 is overlapped with first through hole 3113 and third through-hole 3115 respectively so that adsorb into
Mouth pipe 3141, the cavity of shell 311 and absorption outlet 3142 constitute sorption channel, the absorption of the cleaning equipment used
Inlet tube 3141 and the valve body for adsorbing outlet 3142 are opened, and are adsorbed by filling block 312, when the of the first surge tank 71
When one gas-detecting device detects that discharge index is not achieved in exhaust gas, exhaust gas enters gas inlet pipeline by the first recovery tube 92
1 is adsorbed again, illustrates that 31 quantity of purifier is inadequate at this time, opens 31 quantity of purifier one by one successively so that slow down
The flow velocity of exhaust gas is buffered, the adsorption effect of purifier 31 is improved, until the first gas detection device of the first surge tank 71 is examined
It is that exhaust gas has downtake pipe 91 to be discharged by exhaust high tower to survey air care.
Second stage：Discharge index is not achieved when the first gas detection device of the first surge tank 71 detects exhaust gas again
When, illustrate 312 adsorption saturation of filling block of cleaning equipment, in the purifier 31 to come into operation at this time, 3132 turns of driving motor
It is dynamic that fifth hole 3117 and the 6th through-hole 3118 is caused to be overlapped respectively with the second through-hole 3114 and fourth hole 3116, import is desorbed
The valve body of pipe 3143 and desorption pipe 3144 is opened so that desorption inlet tube 3143, the cavity of shell 311 and desorption go out
Mouth pipe 3144 constitutes desorption channel, other spare purifiers 31 repeat first stage steps and carry out absorption work, and desorption is warm
The generation of source device 4 hot steam makes the substance desorption of absorption, desorption substance enter the condensation of condenser 51, divide in separator 52
From, be incorporated to catalytic combustion system 53 carry out catalyst combustion reaction handled, when the second surge tank 72 second gas detect dress
Set can not detect desorption substance when, purifier 31 is desorbed completely, at this time the second recovery tube 94 valve body closing, second exhaust
93 valve body of pipe is opened, and desorption heat power supply device 4 generates thermal current and filling block 312 is made to dry drying, and air-flow has second exhaust pipe 93
To exhaust high tower discharge, after being dried, be desorbed work purifier 31 carry out it is spare.
Phase III：When spare 31 adsorption saturation of purifier of second stage input absorption, into second stage
The desorption work, the purifier 31 that completion is desorbed at this time put into absorption work described in the first stage, weigh according to this again
Multiple cycle alternation work.
Whether the output object that wherein the third surge tank 73 is used to detect after catalysis burning reaches emission request, if
Detect that catalysis burning is not thorough, harmful substance does not remove thoroughly, then still enters gas inlet pipeline 1 by third return duct
It is handled, can be by third exhaust pipe 95 to exhaust high tower discharge if qualified, the 4th surge tank 74 is for sentencing
The adsorption capacity that disconnected filling block 312 gives up to various concentration, while effectively each purifier 31 is monitored, when the 4th
Surge tank 74 then shows that the full state of absorption occurs in this purifier 31, can switch at any time de- when detecting exhaust gas not situation up to standard
Attached work provides switching another input absorption work of spare purifier 31, while further desorption pipeline 32 and recycling
The purifier 31 different with external size difference, that is, adsorption capacity of pipeline 33, when the 4th surge tank 74 is reached in detection exhaust gas
When less than discharge index, the strong cleaning equipment of the larger adsorption capacity of changeable size is adsorbed.
The structure design of the utility model is reasonable, can carry out the exhaust gas of processing various concentration and flow velocity, while using net
Makeup, which sets to work independently, not to be interfere with each other, convenient in failure, is overhauled in the case where not influencing integral device operation
It replaces, while it is strong to handle exhaust gas logicality, each purifier has independent condition monitoring capabilities, so as to basis in production
State switches corresponding absorption or desorption work, for monitoring while in adsorption/desorption work, ensure that the up to standard of exhaust gas
Discharge.
Described in this specification above content is only to the utility model example explanation.The utility model
Person of ordinary skill in the field can make various modifications or additions to the described embodiments or use class
As mode substitute, content without departing from the utility model specification or surmount model defined in the claims
It encloses, all should belong to the protection range of the utility model.
