Description
Technical field
The invention belongs to energy-conserving and environment-protective technical field, relate in particular to a kind of ozone decomposed method and device thereof.
Background technology
Ozone generator manufacturing company, in actual production process, need to debug, try out each ozone generator before dispatching from the factory, 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 are carried out to the difficult problem that energy-efficient resolution process is a puzzlement enterprise.
General company adopts and adds the method for thermal decomposition, and ozone gas is at 300 DEG C or when above, and in 1-2 reaction time second, 100% decomposes.The method that adopts thus resistance heated or heat burning, allows ozone gas pass through a high temperature service, makes ozone gas Yin Gaowen and instantaneous heat decomposition, is reduced into oxygen.Though the method ozone decomposed effect is high, exists energy consumption large, high risk shortcoming.Be warmed to 300 DEG C and also maintain this high temperature above always, need 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, decomposer design needs highly insulation, and therefore 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 once have an accident.
Adopt in addition the method for conventional catalytic decomposition, fill special catalyst by an oxidizing tower in inside and input from one 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 make full use of and is wasted simultaneously.In the time that accumulated heat is serious, also need catalytic tower to take cooling provision, 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 producing, and fails to make full use of, and has increased on the contrary the consumption of catalyst, and catalytic decomposition efficiency is not high yet.
So the decomposer to high-concentrated ozone gas using at present, exists energy consumption high, dangerous or ozone decomposed produces the low shortcoming of heat utilization ratio.
Summary of the invention
The shortcoming existing for above-mentioned background technology, the technical problem to be solved in the present invention 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 present invention 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 producing in described step is to heating the ozone gas contacting 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 outside, its bottom is provided with gas outlet, described inner tube connects by the hole and the shell that are positioned on bucket sidewall, and described shell is provided with air inlet.
The present invention is without auxiliary heating, after ozone gas contact catalyst, be catalysed and reduced into oxygen, and discharge a large amount of heat energy simultaneously, the a large amount of heat energy that produce in course of reaction have heated the ozone gas contacting with catalyst, meeting high temperature ozone starts to decompose, its concentration declines, and after contacting, is resolved into oxygen completely with catalyst.The present invention uses a small amount of ozone catalytic agent, fully recycles the heat energy that ozone decomposed produces, and high-concentrated ozone gas is carried out to continuous high-efficient and decompose, and reaches safety dumping requirement, is ozone decomposed method and the device of energy-conserving and environment-protective.
Brief description of the drawings
Accompanying drawing is ozonolysis equipment structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is made and being further illustrated.
Ozone decomposed method of the present invention is achieved by ozonolysis equipment as shown in the figure, ozonolysis equipment comprises being furnished with the interior bucket 104 of seal cover board 101 and the shell 102 with interior bucket 104 shared base plates 108, the interlayer of bucket 104 in ozone gas is entered ozonolysis equipment stainless steel casing 102 by air inlet 100 and stainless steel, fully contact and carry out heat exchange, the 1st intensification thermal decomposition of ozone with interior bucket 104; Ozone gas enters stainless steel inner tube 106 by tube connector 107 through the hole 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, and discharge a large amount of heat energy by complete decomposition-reduction; Oxygen is outer or send in retracting device through gas outlet 109 drain chamber.
The heat energy that ozone gas catalytic decomposition discharges has heated catalyst 105, inner tube 106 and interior bucket 104, normal temperature ozone gas produces heat exchange while flowing through, through heating, thermal decomposition occurs, and greatly reduces concentration of ozone gas, alleviate the catalysis load of catalyst 105, reduced the consumption of catalyst simultaneously.
Circulation, has realized low energy consumption and so forth, without heating, utilizes reaction heat release, and high efficiency heat energy recycles, and reaches the process of ozone gas being carried out to repeatedly thermal decomposition and catalytic decomposition.
As preferably, in the interlayer in inner tube 106 and/or stainless steel casing 102 and stainless steel between bucket 104, be provided with spiral deflector 103; Air inlet 100 is positioned at the top of described shell 102, the hole of passing for tube connector 107 on interior bucket 104 sidewalls is positioned at the bottom of sidewall, extend the heat exchanger time of ozone gas, improve heat exchanger effectiveness, further reduced the ozone concentration that enters catalyst and carry out catalytic reaction.
The description of above embodiment is comparatively concrete, detailed; but can not therefore be interpreted as the restriction to this patent scope; it should be noted that; for the person of ordinary skill of the art; without departing from the inventive concept of the premise; can also make some distortion and improvement, these all belong to protection scope of the present invention.
