Operation principle of the present utility model is as follows:

Absorption casing, utilizes VOC_SCollection conduit, the VOC that workshop is produced_SWaste gas is delivered to adsorb casing and is adsorbed Collect, its internal employing honeycomb fashion activated carbon or zeolite, utilize its material to VOC_SGas and abnormal smells from the patient have the absorption of uniqueness The uniqueness of effect, to VOC_SWaste gas is collected, it is to avoid VOC_SGas the most externally discharges, and causes environmental pollution；And utilize Desorption so that adsorbing material can regenerate use.

Catalysis burning bed, including one group of heat-exchanging chamber, one group of electric heater, one group of catalytic bed, one group of combustor；Utilization is urged Change the electric heater in burning bed, cold air is heated, by piping, hot-air is sent into absorption casing, utilize hot-air handle VOC in adsorbing material_SGas is driven out of, after again through piping by desorption out containing VOC_SHot-air sends catalysis burning bed back to, Catalyst in catalytic bed, carries out sufficiently catalytic combustion decomposition in combustor, before discharging through heat-exchanging chamber, Intake air temperature exchange pre-heating temperature elevation, delivery temperature exchange reduce and after through discharge air-valve discharge；Heating in catalysis burning bed Device temperature takes PID control, stably catalyzed temperature.

De-adsorption cycle blower fan, when the electric heater temperature in catalysis burning bed reaches setting value, just starts de-adsorption cycle wind Machine, makes hot-air uniform circulation in system, the VOC in honeycomb fashion activated carbon or zeolite adsorption material_SGas is uniformly caught up with Out, and send back to catalysis burning bed carry out catalysis burning；The renewable recycling of adsorbing material after desorption.

Burning oxygenating air-valve, utilizes the temperature difference of the heater chamber in catalysis burning bed and combustor, and combustor is more than heating Device room temperature difference, judges whether it possesses burning condition, if possessing burning condition, and time opening minimum aperture, carry out one Supplementing of oxygen-containing air of fixing time, to help its catalysis burning.If heater chamber and the temperature approach of combustor are more than abundant burning Condition, then stop supplementing oxygen-containing air, in order to avoid ignition temperature is too high.When its ignition temperature difference is less than abundant fuel value, It is again turned on timing and supplements oxygen-containing air action；Its main effect is to control the required oxygen of burning, controls ignition temperature, controls The stability of burning, makes VOC_SGas is the sufficiently catalytic burning of consistent in catalysis burning bed.

Circulation blow valve, cold air electric heater in catalysis burning bed, flow through circulation through piping after heating and send Hot-air is sent into absorption casing by air-valve, carries out VOC_SDesorbing gas；VOC in catalysis burning bed_SWhen gas combustion is abundant, Minimum aperture opened by circulation blow valve, to avoid wind pushing temperature too high, causes the potential safety hazard of absorption casing, and utilizes minimum to open Spend and provide uniform heat to absorption casing, continual carry out VOC_SDesorbing gas；When the ignition temperature in catalysis burning bed surpasses When crossing setting higher limit, circulation blow valve regulation is closed, and after burning, hot-air is directly arranged via outside discharge air-valve, it is ensured that at system In safe mode；When desorption completes to cool, circulation blow valve cuts out, and carries out pressure via discharge air-valve and cools； Its Main Function is the wind pushing temperature after controlling burning and outer parallelism example, it is to avoid high temperature abnormality occurs in system.

Return air cooling valve, controls air supply duct temperature, by PID control, utilizes return air duct cold wind, carry out wind pushing temperature Regulation management and control, and control the VOC of proper proportion_SGas is even into catalytic combustor, continual and steady burning；When possessing During burning condition, return air cooling valve opens minimum aperture, controls temperature and does not wants acute variation；Burning temperature in catalysis burning bed When degree exceedes setting higher limit, return air cooling valve is closed, and after burning, hot-air is directly arranged via outside discharge air-valve, it is ensured that at system In safe mode, when desorption completes to cool, the regulation of return air cooling valve is closed, and cools via discharge air-valve； Its Main Function is, the wind pushing temperature of system is played conclusive effect, controls the VOC of proper proportion_SGas even into Catalytic combustor, continual and steady burning；Via PID control, utilize return air cold air, regulate stable feeding air temperature and burn dense Degree.

Discharge air-valve, links with burning oxygenating air-valve, when the oxygenating air-valve that burns is opened, and its corresponding united opening, When chamber temperature reaches to burn setting value, carrying out PID and automatically control, when desorption completes to cool, discharge air-valve is complete Drive row cooling into；Its Main Function is linkage oxygenating effect of playing together with burning oxygenating air-valve, in complete combustion process externally Discharge use, and it has been desorbed use when cooling.

Cooling blower and cooling air-valve, when high-temperature exception occurs in system, open cooling blower and carry out with cooling air-valve Forced cooling；Or system has been desorbed the use that cools；When high temperature alarm occurs in system, cooling blower is opened, and cools down wind Valve is opened 50% and is carried out forced cooling；When temperature over-range occurs in system, cooling blower is opened, and cooling air-valve is opened 100% and entered Row forced cooling；Desorption completes, and when cooling, cooling blower is opened, and cools down air-valve 100% standard-sized sheet.

The above is only preferred implementation of the present utility model, is not limited to this utility model, it is noted that For those skilled in the art, on the premise of without departing from this utility model know-why, it is also possible to do Going out some improvement and modification, these improve and modification also should be regarded as protection domain of the present utility model.
