The specific embodiment
Below in conjunction with accompanying drawing the utility model is done explanation further:
Like Fig. 1, a kind of organic waste gas catalytic combustion cleaning equipment shown in 2, comprise that air inlet 1, intake stack 2, air inlet 1 are positioned at the two ends of intake stack 2, intake stack 2 bottoms are connected with adsorption chamber 4 through air inlet pneumatic operated valve 3; Place adsorbent 5 in the adsorption chamber 4; Catalytic combustor 6 is positioned at adsorption chamber 4 belows, is provided with heating tube 7, catalyst 8 in the catalytic combustor 6, is provided with catalytic combustor intake valve 10 between catalytic combustor 6 and the pipeline 9; Be provided with catalytic combustor air bleeding valve 12 between catalytic combustor 6 and the pipeline that blower fan 11 is connected; Blower fan 11 is connected with pipeline 9, is provided with spark arrester 15 between pipeline 9 and the by-pass line 14, is connected through hot blast air inlet motor-driven valve 16 between pipeline 9 and the adsorption chamber 4; Air inlet pneumatic operated valve 3 tops are desorption exhaust motor-driven valve 17; By-pass line 14 tops are provided with exhaust pneumatic operated valve 18, and air outlet 19 is positioned at pipeline 9 two ends, and pipeline 9 is provided with motor-driven valve 13 with by-pass line 14; Described adsorbent 5 is the Alveolate activated carbon capable adsorbent; Described heating tube 7 materials are stainless steel; Described catalyst 8 is precious metal palladium, platinum.
The process for purifying of organic exhaust gas is: absorption-desorption-catalytic combustion.
Absorbing process: organic exhaust gas gets into adsorption chamber 4 through air inlet 1, and what place in the adsorption chamber 4 is Alveolate activated carbon capable adsorbent 5, and the air of organic exhaust gas after absorption is cleaned air passes, discharges through air outlet 19.
Separating process: after adsorbent 5 absorption is saturated, use the organic solvent that is adsorbed on the adsorbent 5 thermal current that produces through catalytic combustor 6 to deviate from, and be sent to catalytic combustor 6 and burn by certain cocnentration factor.Thermal current gets into adsorption chamber 4 behind blower fan 11 and spark arrester 15, by the following air inlet entering of adsorption chamber 4, the upper outlet of adsorption chamber 4 is discharged the desorption air-flow, behind the desorption pipeline, gets into catalytic combustor 6 once more and burns.
Catalytic combustion technology: catalytic combustor 6 is made up of heating tube 7 and catalyst 8 (palladium, platinum).After getting into the organic exhaust gas process heating tube 7 further heating of catalytic combustor 6, oxidation Decomposition under the effect that with precious metal palladium, platinum is catalyst 8 is converted into carbon dioxide and water.Decompose the heat that discharges and behind blower fan 11, send into adsorption chamber 4, with saturated adsorbent 5 desorption and regenerations.
The organic waste gas catalytic combustion cleaning equipment has automatic, manual two kinds of modes of operation, and when adopting automatic working method, equipment has full-automatic startup, operation, shutdown, and function such as warning; When adopting the manual work mode, operating personnel can start any apparatus as required.According to technological requirement, can change the control parameter, as: desorption cycle, adsorption cycle etc.
After pressing start button, then system is in automatic work.After the startup, the waste gas inlet and outlet, air draft blower fan (figure does not show, is positioned at air outlet 19 places) can not put into operation at once, because when beginning startup, system's first step is required to be catalytic combustor 6 and carries out preheating.
When circulation was heated in the catalytic combustor 6, by-pass line motor-driven valve 13 was opened, and carries out exhaust, made that the temperature in the catalytic combustor 6 are heated to uniform temperature.Its temperature is limited to 190 ℃ under setting, and the heat exchange lowest temperature is 280 ℃, and ceiling temperature is 400 ℃.
When preheat temperature reached the temperature upper limit setting value, blower fan 11 started, and catalytic combustor intake valve 10, catalytic combustor air bleeding valve 12 are opened work.When temperature reached lower limit, blower fan 11 stopped, and catalytic combustor intake valve 10, catalytic combustor air bleeding valve 12 are closed, and corresponding indicator lamp goes out.When blower fan 11 continuous operations, when catalytic combustor 6 temperature rose to the temperature preset lower limit, system's absorption, desorption began automatic work; (figure does not show the air draft blower fan; At air outlet 19 places) start working, and remain in system's running, each unit absorption, desorption can be recycled.
When adsorption chamber 4 beginning absorbing process, air inlet pneumatic operated valve 3 is opened with exhaust pneumatic operated valve 18, and hot blast air inlet motor-driven valve 16 cuts out with desorption exhaust motor-driven valve 17 automatically.When adsorption chamber 4 be adsorbed to saturated after, need carry out the regeneration of adsorbent 5, thus adsorption chamber 4 wherein a unit stop absorption, carry out separating process.When separating process carried out, hot blast air inlet motor-driven valve 16 was opened with desorption exhaust motor-driven valve 17 automatically, and air inlet pneumatic operated valve 3 cuts out with exhaust pneumatic operated valve 18 automatically, the beginning separating process.
When adsorption chamber 4 (needing desorption after adsorption chamber 4 absorption the are saturated) setting-up time of working (20 minutes); Then mend low temperature valve (figure does not show) and start working, adsorption chamber 4 is in the dry state of cooling (10 minutes), after the cooling; Adsorption chamber 4 is in dormant state, and this moment, hot-air system continued circulation.
After carrying out parking, system can not stop immediately, must after separating process is covered, could all stop.
