Description

High-efficiency and energy-saving fluid decontamination and inactivation device

[0001] An energy-efficient fluid decontamination and inactivation device belongs to the technical field of fluid removal.

Background technique

[0002] Ozone is an allotrope of oxygen. At normal temperature, ozone is a blue gas with a special odor. Ozone has many uses, and it can deeply treat industrial sewage, domestic sewage and hospital sewage. Remove all kinds of impurities in water, can be sterilized and sterilized; ozone can remove scale and prevent blocking of pipelines; use ozone to sterilize and sterilize residues that are harmful to human body (such as chlorine-sterilized carcinogenic halogenated organic matter), The quality of disinfection of drinking water is very effective. At present, the application of ozone is still accelerating, and the high-quality oxide film formation process, the photoresist film corrosion cleaning process, the ozone ice preparation, the medical and health aspects, etc. in the field of semiconductor manufacturing are inseparable from the ultra-high concentration. Ultra high purity ozone. The above various uses of ozone are based on the fact that ozone reaches a certain concentration and a certain high purity. Therefore, the development of ozone technology is aimed at high concentration, high purity and low consumption.

[0003] The development of artificially manufactured ozone technology has also been more than one hundred years old. At present, it is widely used that the ozone generator corona discharges oxygen or air in the air gap to generate ozone. Nowadays, industrial ozone is usually produced from industrial oxygen. Since industrial oxygen contains impurities such as carbon monoxide, methane and acetylene, the ozone produced contains impurities such as carbon monoxide, methane and acetylene, and is flammable gas such as carbon monoxide, methane or acetylene. The presence of ozone affects the use of ozone. Generally, these impurities are removed by conventional filtration, absorption, low-temperature precious metal catalysis, molecular sieve adsorption, etc., and the cost of removing impurities is high, and the removal effect cannot be guaranteed. This is mainly because the effectiveness of the work of substances such as molecular sieves and low-temperature catalysts cannot be quantitatively evaluated. At present, there is no system theory and evaluation index system for how to remove chemical gases and liquids with small impurity content in the industry. Although a impurity removal device is installed in a production system, the impurity removal effect is very poor, and the impurity removal equipment often has the same arrangement. This has led to the current international and domestic chemical processing equipment work cycle is not long, and some large equipment often have a work cycle less than one year will be discontinued maintenance. The current ozone production equipment is also the same, the working cycle is extremely short, usually about one year. To achieve this work cycle, the equipment should be disassembled, cleaned and maintained. This causes inconvenience and cost increase for the user. [0004] At present, in the chemical industry, air separation industry and ozone industry at home and abroad, there is no ideal and feasible technical process device for how to remove impurities from raw material gases. The problem of exposure has the effect of removing impurities and energy consumption. It is necessary to replace the impurity components regularly. This poses a great challenge to the operation of the ozone generator unit. From the perspective of the ozone industry, from the birth to the present more than 100 years, there is no solution to the interference of impurities on equipment and production. This is a serious problem that has been plaguing the industry. This requires us to make great efforts in theory and practice to explore and research and develop a device to completely solve this problem.

[0053] New theories and experiments prove that the excessively high electric field strength Td, when the average energy of the electrons is greater than 20 ev, the excessive energy applied will be transferred in a heat-generating manner and will thermally decompose the ozone. The ionization of oxygen molecules is excited into active particles, and the formation of ozone molecules by collision does not help much. Microscopically, when the oxygen molecules get less than 20 ev, the electric field strength is not too high. According to the new theory, a condition is designed in which a relatively low electric field strength is used, which is 300-700 Td. The average distance of the molecules in the physical space is 510, and the length of the channel is 800 mm. The utility model also provides a plurality of uniform discharge channels of active free electrons, which reduces the diameter of the micro-discharge column and increases the density of the electric column by 2 to 3 times, and the equivalently greatly increases the discharge area, which can greatly improve the dynamic effect of oxygen molecular dissociation. Oxygen molecular dissociation, ionization and three-body collision generation Ozone plasma reaction process is represented by the following formula:

O ₂ (x ³ Lg )+e^O ₂ (A ³ Lu ⁺ ) +e

O ( ³ P) +0 ( ³ P) +e

0( 'D)+0( ³ P)+e

O ₂ (x ³ Eg-)+e 0 ₂ (A ³ JTU ⁺ ) +e

-^O ( ³ P) +0 ⁺ ( ^! S °) +2e

[0060] o+o ₂ +M o ₃ +M o ₃ +M

[0061] As shown in FIG. 7, the oxygen molecules have a maximum dissociation cross-sectional area when the electron energy is about 20 ev. The 20 ev electron energy is 0 ₂ (x ³ I: g -) 0 ₂ (B ³ I: u -) is more than twice as long as the forbidden transition O ₂ (x ³ I: g -) 0 ₂ (A ³ [ u ⁺ ) is more than 3 times. Experiments show that the electron energy of 20 ev should be the boundary value of high concentration and low power.

[0062] As shown in FIG. 8 : the electric field strength expressions of the dielectric and the air gap electric field in the discharge channel are respectively

(2)

[0065] In the above formula, U is a voltage application peak,

E d

Is the dielectric constant of the dielectric,

For the thickness of the medium,

For the air gap distance,

It is the dielectric constant of the air gap. It can be seen from equation (2) that the electric field strength of the air gap increases with the increase of U, with Increase and decrease

The decrease increases.

[0066] As shown in FIG. 9, the electric field strength of the electron average energy of 700 deg of 20 ev can be satisfied. It is worth pointing out that the above are only the basic conditions for the conversion of oxygen molecules to ozone, but not all conditions. Studies have shown that electric field energy application is not the only provider of active particles, nor is it the optimal power of all active particles. The cold unbalanced thermal plasma requires the induction of other activations. The conditions set above also verify the correctness of this inference.

[0067] According to the above design conditions, a sophisticated air-gap discharge ozone large-capacity industrial generator was designed and developed, resulting in an ultra-high ozone concentration of 660 g/Nm3 (40 wt%), which directly produced ozone concentration by the ozone generator. The highest value ever seen in the world, power consumption S

12kwh/kgo3

At this ultra-high concentration, the power consumption is currently the lowest in the world. The appearance of this ultra-high concentration and low power consumption fully proves the correctness of the theory and modeling of micro-discharge, and makes a big step in the theory and technology of ozone discharge. Achieving a rise in concentration and a simultaneous decline in power consumption have opened the door to low-cost preparation of ozone. The intended effects of the present invention are achieved.

The present invention also provides a method for ozone flow detection, wherein a mass flow meter is disposed on both the intake pipe 4 and the outlet pipe 5, and both mass flow meters are connected to the PLC controller. Specifically, the following steps are included:

[0069] Step 1), under the same conditions, real-time measurement of the volume flow of the gas before the chemical reaction occurs and the volume flow rate Q ₂ of the gas after the chemical reaction occurs _;

[0070] In this embodiment, the chemical reaction that occurs is a chemical reaction in which oxygen is converted to ozone. Under the same temperature conditions and pressure conditions, the volume flow rate Q _{h of the} incoming gas is measured in real time, and the volume flow rate Q _{2 of the} discharged gas is measured in real time, and Q ₂ includes the ozone volume flow rate 0 ₃ and the unreacted oxygen flow rate Q ₄ . It is also possible to measure the mass flow rate of the gas before the reaction in real time, and calculate the volume flow rate based on the measured mass flow rate and the density of the gas.

[0071] Step 2), calculating the real-time volume flow difference AQ of the fluid before and after the chemical reaction, [0072] AQ=IQ _r Q ₂ l;

[0073] The chemical equation for the conversion of oxygen to ozone is as follows: 30 ₂ =20 _3° Since the volume of the gas after the chemical reaction is reduced, AQ=Q r Q _2° If the volume of the gas after the chemical reaction increases, AQ =Q ₂ -

Q ₁ .

[0074] Step 3), calculating the volume flow rate Q _{3 of the} fluid to be detected after the reaction _;

[0075] It can be seen from the above chemical equation that every 3 L of oxygen can be converted into 2 L of ozone, that is, the conversion ratio is 1.

5:1, from which the following relationship can be derived:

[0076] Q i = 1.5Q ₃ + Q ₄ ;

Wherein Q ₄ is the volume flow rate of Q ₂ that does not participate in the reaction under the same conditions.

[0078] The exhausted gas is a mixed gas of ozone and oxygen that does not participate in the reaction, and can obtain:

Q ₂ =Q ₃ +Q _4; (4)

[0080] Substituting the formula (3) into the formula ( ⁴ ) can be obtained:

Q ₃ = 2 (Q _r Q ₂ ); (5)

[0082] Step 4) Calculate the percentage concentration of ozone mass of the fluid to be detected C:
