Description

Ozonolysis equipment

Technical field

The utility model belongs to the energy-conserving and environment-protective technical field, relates in particular to a kind of ozone decomposed method and device thereof.

Background technology

Ozone generator manufacturing company need to debug, try out each ozone generator before dispatching from the factory in the production process of reality, thus can a lot of ozone gas of output.These concentration of ozone gas are high, and flow is large, and there is no practical use, can only resolution process externally discharge.Therefore how these ozone gas being carried out energy-efficient resolution process is a difficult problem that perplexs enterprise.

General company adopts the method add thermal decomposition, and ozone gas is at 300 ℃ or when above, and in 1-2 reaction time second, 100% decomposes.Adopt thus the method for resistance heated or heat burning, allow ozone gas pass through a high temperature service, make ozone gas Yin Gaowen and the instantaneous heat decomposition, be reduced into oxygen.Though the method ozone decomposed effect is high, exists energy consumption large, high risk shortcoming.Be warmed to more than 300 ℃ and keep this high temperature always, needing to consume mass energy; The power of heating is corresponding with ozone gas amount simultaneously, and the larger chargeable heat power of tolerance is larger, and because temperature is very high, the decomposer design needs highly insulation, so this decomposition technique use cost is very high.Because the ozone reduction of high-temperature heating becomes oxygen, there is certain security risk, very easily cause explosion danger in case have an accident.

Adopt in addition the method for conventional catalytic decomposition, namely fill special catalyst by an oxidizing tower in inside and input from an end of tower by the ozone gas of high concentration, the other end is discharged, and makes its decomposition-reduction under the effect of catalyst become oxygen.

Ozone decomposed is an exothermal reaction process, discharges a large amount of heat energy in this process.Whole reaction unit heating is serious, causes the temperature of catalyst itself also very high, and the best catalytic temperature that even exceeds catalyst causes its inefficacy; This part heat energy is failed to take full advantage of and is wasted simultaneously.Also need catalytic tower is taked cooling provision when accumulated heat is serious, in order to make catalyst carry out cartalytic decomposition effect under optimum temperature.

Although the method is energy-conservation simple, effect is decomposed in the heat energy impact that produces, and fails to take full advantage of, and has increased on the contrary the consumption of catalyst, and catalytic decomposition efficient is not high yet.

So the decomposer to high-concentrated ozone gas that uses at present exists energy consumption high, dangerous or ozone decomposed produces the low shortcoming of heat utilization ratio.

The utility model content

For the shortcoming that the above-mentioned background technology exists, the technical problems to be solved in the utility model is to provide a kind of low energy consumption, and high efficiency is utilized ozone decomposed method and the device of heat circulation.

For solving the problems of the technologies described above, the utility model is achieved by the following technical programs:

A kind of ozone decomposed method comprises that ozone gas contacts the step of decomposing with catalyst, and the heat that produces in described step heats the ozone gas that will contact with catalyst.

A kind of ozonolysis equipment of realizing above-mentioned ozone decomposed method, comprise bucket in the sealing that ozone decomposition catalyst is housed, the inside of described interior bucket is provided with inner tube, Packed shell is established in the outside, its bottom is provided with the gas outlet, described inner tube connects by hole and the shell that is positioned on the bucket sidewall, and described shell is provided with air inlet.

The utility model need not auxiliary heating, be catalysed and reduced into oxygen after the ozone gas contact catalyst, and discharge simultaneously a large amount of heat energy, the a large amount of heat energy that produce in course of reaction have heated the ozone gas that will contact with catalyst, meeting high temperature ozone begins to decompose, its concentration descends, and is resolved into oxygen fully after contacting with catalyst.The utility model uses a small amount of ozone catalytic agent, and the heat energy that abundant recycling ozone decomposed produces carries out continuous high-efficient ground decomposition to high-concentrated ozone gas, reaches the safety dumping requirement, is ozone decomposed method and the device of energy-conserving and environment-protective.

Accompanying drawing is the utility model ozonolysis equipment structural representation.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is made and being further illustrated.

The utility model ozone decomposed method is achieved by ozonolysis equipment as shown in the figure, ozonolysis equipment comprises the interior bucket 104 of being furnished with seal cover board 101 and shares the shell 102 of base plates 108 with interior bucket 104, the interlayer of bucket 104 in ozone gas is entered ozonolysis equipment by air inlet 100 stainless steel casing 102 and stainless steel, fully contact with interior bucket 104 and carry out heat exchange, the 1st intensification thermal decomposition of ozone; Ozone gas enters stainless steel inner tube 106 by the hole that tube connector 107 passes on interior bucket sidewall, the 2nd heat exchange in inner tube 106, and ozone is by the 2nd intensification thermal decomposition; Ozone gas enters catalyst 105 by inner tube 106 tops, has carried out catalytic decomposition and thermal decomposition for the third time, is become oxygen by decomposition-reduction fully, and discharges a large amount of heat energy; Oxygen is outer or send in retracting device through gas outlet 109 drain chamber.

The heat energy that the ozone gas catalytic decomposition discharges has heated catalyst 105, inner tube 106 and interior bucket 104, produce heat exchange when the normal temperature ozone gas flows through, through heating, thermal decomposition occurs, greatly reduce concentration of ozone gas, alleviate the catalysis load of catalyst 105, reduced simultaneously the consumption of catalyst.

Circulation, realized low energy consumption and so forth, need not heating, utilizes the reaction heat release, and high efficiency heat energy is recycling, reaches the process of ozone gas being carried out repeatedly thermal decomposition and catalytic decomposition.
