4. interior electrode is linked to each other with lead with another electrode of high-voltage ac power;
5. open the argon gas valve and adjust gas flow rate to 3L/s, the calcium carbonate powder in the fluid bed will fluidisation, controls gas flow rate by the gas flowmeter on the gas circuit, and when gas flow rate reached predetermined fluidizing velocity, dusty material will be in the fluidisation attitude; (different granular sizes, different air velocities);
6. regulate high-voltage ac power and will in fluid bed, produce plasma to 10KV, at this moment in argon gas, add HMDO steam, this organosilicon steam will be ionized into active group under action of plasma, form organosilyl low surface aggregate thing on the calcium carbonate powder surface, calcium carbonate powder just becomes hydrophobic material like this.
Two, waste water and gas is handled
Processing has three kinds of pattern: a. separately to the wastewater treatment pattern to waste water and gas at this contrive equipment; B. separately to the exhaust-gas treatment pattern; C. waste water and gas tupe simultaneously.For example utilizing Fig. 3. device is handled chemical plant wastewater and vehicle exhaust.
A. independent wastewater treatment pattern
The waste water that the chemical plant is discharged feeds external electrode (also can make waste water cycle through external electrode), bubbling air in the discharge tube, repeat step to the embodiment one of dusty material processing method, regulate high-voltage ac power to 10KV, make and produce plasma in the fluid bed and make the air of ionization pass through waste water, under the oxidisability active group in ionized air and the effect of plasma middle-ultraviolet lamp, waste water can effectively be degraded.
B. carry out the processing of waste gas (vehicle exhaust) separately:
External electrode can add any conducting liquid, and present embodiment is with KCl or the formulated conducting solution of NaCl inorganic salts, also available other any type of electrode, and on gas distributor, add catalyst granules corresponding to pending waste gas as V 2O 5, TiO 2Deng, repeating step to the embodiment one of dusty material processing method, vehicle exhaust feeds from bed body air inlet, by gas flowmeter control gas flow rate, makes its flow velocity be less than the carrying velocity of catalyst, after it flows through region of discharge, the NO in the waste gas, SO 2Will be oxidized to gas soluble in water Deng pernicious gas, reach the purpose of processing.
When C. waste water and gas is handled simultaneously: logical waste water in the external electrode shell, the tail gas that is open to the traffic in the discharge tube, and on gas distributor, add catalyst V 2O 5, TiO 2Deng, through waste water by adding alkali after after handling of the waste gas of region of discharge (in waste water, add an amount of alkali can with the sour gas reaction in the waste gas, thereby sour gas is filtered), will sour gas oxidized and soluble in water in the waste gas be filtered, acid and alkali generation neutralization reaction that sour gas generates become innocuous substance.
The discharge type of these three kinds of patterns is identical with calcium carbonate powder modification operation form, will not tire out and state.
