Abstract

The invention relates to a novel method for carrying out a rapid catalytic decomposition process on high concentration ozone gas at normal temperature through an effect from a high-intensity magnetic field. The novel method is characterized in that a strong magnetic magnet and catalyst powder are composed into a catalyst carrier, wherein air can flow through the catalyst carrier; the catalyst powder around the strong magnetic magnet is effected by a magnetic field produced by the strong magnetic magnet thus a catalytic activity of the catalyst powder is stimulated; and air flows through the catalyst carrier under an effect of a blower fan thus a purpose of ozone gas decomposition is realized. The novel method has the characteristics of low cost, long service life, high and stable rate of decomposition, and no restriction on temperature and humidity. The novel method can be utilized widely for catalytic decomposition of residual ozone gas in air after the processes of ozone deodorization and sterilization, waste water processing and air cleaning.

Description

A kind of under the effect of strong magnetic magnetic field the new method of catalytic decomposition ozone

[technical field]

The present invention relates to a kind of by the effect of strong magnetic magnetic field, at normal temperatures moment catalytic decomposition high-concentrated ozone gas new method, specifically with strong magnetic magnet and the powder that is used as catalyst, be combined into a kind of catalyst carrier of the air of flowing through, the magnetic field that utilizes strong magnetic magnet to produce, act on the catalyst powder of strong magnetic magnet periphery, excite the catalytic activity of catalyst powder, under the effect of blower fan, make the air catalyst carrier of flowing through, reach the purpose that moment at normal temperatures decomposes high-concentrated ozone gas.

[background technology]

Ozone has extremely strong oxidisability, all has at aspects such as deodorizing sterilizing, wastewater treatment, air cleanings comparatively widely to use.Yet, in application process, if not adding, remaining ozone with high concentration do not handle directly discharging, will bring the harm of secondary pollution to surrounding enviroment, when adopting high-concentrated ozone to dispose of sewage, the ozone that has a 10%--20% can't dissolve in fully in the water and overflow, therefore, this part ozone that overflows must adopt various suitable means to remove, and can not directly discharge.In various removing means, it is a kind of than simple effective method adopting ozone catalytic agent quick catalysis ozone decomposition gas.

Known ozone catalytic agent technology has transition metal series before month, noble metal series, types such as compounding ingredients series, the carrier of these ozone catalytic agent mostly adopts active carbon, gama-alumina, molecular sieve, material such as reticular polyurethane and cordierite, all take in the making to prepare with preparation, carrier impregnation, cure drying, this pattern of high-temperature roasting is the series of processes of standard, the product of making all exists catalytic effect and is subjected to temperature difference influence big (effective when temperature is high, otherwise it is then poor), moisture resistance is poor, need noble metal as co-catalyst, the more high major defect of use cost.

[summary of the invention]

The present invention is in order to overcome above-mentioned deficiency, designed a kind of in suitable ventilation shaft, be provided with by strong magnetic magnet, magnesium oxide powder and sponge as catalyst, be combined into a kind of under the effect of blower fan, the catalyst carrier that air can more smooth and easyly be flowed through, the magnetic field that utilizes strong magnetic magnet to produce, act on the magnesium oxide powder of strong magnetic magnet periphery, excite the catalytic activity of magnesium oxide powder, suck the air contain high-concentrated ozone gas by blower fan, make the air catalyst carrier of flowing through, reach the purpose that moment at normal temperatures decomposes high-concentrated ozone gas.

New method is by strong magnetic magnet, fill the sponge A of magnesium oxide powder, fill the sponge B of magnesium oxide powder, magnesium oxide powder, intercept powder loss sponge, ventilation shaft, blower fan, the ventilation shaft air intake, the ventilation shaft air outlet slit is formed, the magnetic field that utilizes strong magnetic magnet to produce, act on the magnesium oxide powder of strong magnetic magnet periphery, excite the catalytic activity of magnesium oxide powder, after opening blower fan, the air that contains high-concentrated ozone gas is inhaled into from the ventilation shaft air intake under the effect of blower fan, air is flowed through by strong magnetic magnet, magnesium oxide powder, fill the sponge A of magnesium oxide powder, fill the sponge B of magnesium oxide powder, intercept the catalyst carrier that powder loss sponge is formed, discharge from the ventilation shaft air outlet slit, can reach the purpose of moment decomposition high-concentrated ozone gas at normal temperatures.

For achieving the above object, designed a kind of under magnetic field effect the new method of catalytic decomposition ozone, comprise strong magnetic magnet, fill magnesium oxide powder sponge A, fill sponge B, magnesium oxide powder, obstruct powder loss sponge, ventilation shaft, blower fan, ventilation shaft air intake, the ventilation shaft air outlet slit of magnesium oxide powder.

It is characterized in that strong magnetic magnet (1) places sponge A (2) that fills magnesium oxide powder and the centre of filling the sponge B (3) of magnesium oxide powder, at the sponge A (2) that fills magnesium oxide powder with fill the mezzanine space filling magnesium oxide powder (4) of the sponge B (3) of magnesium oxide powder, intercept powder loss sponge (5) and be close to the sponge A (2) that fills magnesium oxide powder, the integral body of being made up of to (5) (1) places in the ventilation shaft (6), blower fan (7) places ventilation shaft air outlet slit (9) to locate, air is inhaled into from ventilation shaft air intake (8), discharges from ventilation shaft air outlet slit (9).

The operation principle of apparatus of the present invention is: by the sponge A (2) of strong magnetic magnet (1) and filling magnesium oxide powder, fill the sponge B (3) of magnesium oxide powder, magnesium oxide powder (4), intercept powder loss sponge (5) and form an ozone catalytic agent carrier, place in the ventilation shaft (6), strong magnetic magnet (1) forever produces powerful magnetic field, magnetic field acts on the magnesium oxide powder (4) that strong magnetic magnet (1) periphery is filled, and the sponge A (2) that fills magnesium oxide powder, magnesium oxide powder among the sponge B (3) of filling magnesium oxide powder, excite the catalytic activity of magnesium oxide powder, ozone is formed powerful catalyticing decomposition action.Under the effect of blower fan (7), after air is inhaled into from ventilation shaft air intake (8), the ozone catalytic agent carrier of can flowing through more swimmingly, contained high-concentrated ozone gas and magnesium oxide powder are under the effect in magnetic field in the air, the cartalytic decomposition effect of moment takes place, ozone gas is broken down into oxygen, discharges from ventilation shaft air outlet slit (9) again, reaches the purpose of moment decomposition high-concentrated ozone gas at normal temperatures.The size of the sponge B (3) of the sponge A (2) of filling magnesium oxide powder, filling magnesium oxide powder, thickness, the size of the loading of magnesium oxide powder (4) and strong magnetic magnet (1), number of the arrangement then should be according to the concentration of ozone gas, and actual needs such as draft capacity/h are determined.

Compared with prior art, advantage of the present invention is: 1. cost is low, and is easy to make because do not add noble metal, adds the product of noble metal with prior art and compares, and cost has only less than 1%.2. long service life, and can under the high-concentrated ozone condition, work for a long time.3. resolution ratio is high and stable, owing to be not subjected to the influence of temperature and humidity, but the decomposing state stable for extended periods of time.
