Description

Ozone heating device and method thereof
Technical Field
The disclosure belongs to the field of ozone heating, and particularly relates to an ozone heating device and an ozone heating method.
Background
The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art.
Ozone is a substance with very strong oxidizing ability, and when other substances (except fluorine) are encountered, the substances can be oxidized and the ozone can be decomposed into oxygen, so that special attention needs to be paid to how to reduce the oxidative decomposition of the ozone during heating, and the concentration of the ozone gas after heating can not be reduced only by reducing the decomposition of the ozone. Ozone gas has a short half-life at room temperature, and decomposition prevention is a problem to be considered particularly in ozone heating.
Experiments show that the half-life period is about 10 hours at 26-27 ℃, about 14-16 hours at 24.5-25 ℃, and about 14-20 hours at 19.5-20.0 ℃. This indicates that the activity of ozone (the oxidizing power of ozone) shows an exponential nonlinear rapid increase with increasing temperature, and the activity increases dramatically. In the practical application of ozone, the oxidation capability of ozone at normal temperature can not meet the needs of people. For example, ozone is used to treat wastewater and oxidize impurities in wastewater, and there are two phenomena, one is slow and the other is poor reaction effect, so people have to research a new technology, namely an ozone catalyst, to improve the oxidizing ability of ozone, so as to achieve the purposes of quick oxidation and treatment effect improvement. Ozone is then used, for example, to decompose photoresist in the production of integrated circuits. At normal temperature, the time for decomposing the photoresist by ozone is too long, and the photoresist is not clean and is easy to remain. However, the time for decomposing the photoresist after increasing the temperature of ozone (about 80 ℃) is short, and the photoresist is clean and has no residue. It is a pursuit goal to increase the operating temperature of ozone to achieve high oxidation capacity of ozone.
The inventor finds that the conventional heating device generally only considers that the heating material is heated to the set temperature, calculates the quantity and the temperature value of the heating material and the required heating electric power, does not consider the temperature field distribution of the heating device, and does not consider the connection between the heating device and the normal temperature. When the heating mass enters the heating device, it encounters a temperature difference or several temperature difference steps, which is actually a step of energy (electrical heating). When the heating substance is excited by the energy step, the quantum transition of the substance molecule occurs, and the ozone molecule is decomposed due to the quantum transition of the substance molecule.

As known from the background art, there is no way to heat ozone due to the restriction that the decomposition of ozone at high temperature is rapidly promoted. To date there is no established solution to achieve heating of ozone. According to quantum mechanics, heating is a change of the spin state of molecules, if the electron orbit of an atom is violently collided by the outside, the rotation of the atom is in an excited state, and the change of the electron orbit of the atom is a process that ozone molecules are decomposed and are re-synthesized into oxygen molecules. Heating of ozone in such a heating device entails decomposition of the ozone. Therefore, the distribution of the heating temperature field of the ozone heating device is necessarily considered in an important way, so that the occurrence and the existence of large temperature difference are prevented, and the smooth connection between the heating temperature field of the ozone heating device and the ambient temperature is realized.
