Description

Plate module type ozone generator {Plate Module Type Ozone generator}

The present invention relates to a plate modular ozone generator, comprising a high voltage terminal box, 24 sets of discharge cells, an oxygen pipeline, an ozone pipeline, a cooling water supply pipe, and a cooling water recovery pipe. It is composed of a water return pipe and a generator support structure, and has a small volume and power consumption compared to other existing ozone generators, but has high ozone production and concentration. It also relates to a plate module-type ozone generator that has non-pressure, explosion-proof and flame-retardant functions, and is safer and further improves the reliability of the product by allowing the working status of the generator to be checked on-site or remotely through a display in real time.

Ozone production using low-temperature plasma technology has a 100-year history.

With recent technological advancements, ozone generators using DBD (Dielectric Barrier Discharge Interceptor) technology have been released. DBD's ozone generator has characteristics such as small volume, large yield, low concentration reduction, low power consumption, and easy maintenance compared to existing tube structure ozone generators, and all performances, including device safety and stability, are superior to the tube type. .

The importance of the environment, which directly affects human health, continues to be emphasized, and as regulatory standards for the environment, such as fine dust, have recently been strengthened, the demand for air quality management and water pollution management that improves air quality continues to increase. Many companies and researchers develop numerous environmental technologies to reduce pollutants emitted and apply them to the field to control air and water quality.

Meanwhile, ozone is a strong oxidizing agent that does not cause secondary pollution and has been used for a wide range of purposes for a long time. However, due to the characteristics of ozone that are difficult to store and distribute, ozone generators must be installed where ozone is needed, but the cost of ozone generators is high, making field application difficult.

Therefore, there is an urgent need to supply ozone generators that provide high performance, high stability, high reliability, and high level of security with low initial introduction and operating costs.

Ozone generators are divided into tube type and plate type depending on their structure. The ozone generators that have been distributed in the field so far are tubular and have a cellular structure including a cylindrical container, tubular electrodes, and a porous flange, and an earth electrode. The cylindrical container contains an internal cooling water pipe inside, and is an integrated piece in which the tube electrode and the cylindrical container are welded together. The disadvantage of the tube type is that there is a lot of deformation during welding, making assembly difficult and maintenance difficult. In addition, there are many connection parts, so it is not easy to seal, the coolant pipes are unreasonable, and the number of parts is very large, so it is difficult to find the cause when a problem occurs in the device.

The plate module type ozone generator of the present invention was developed to solve the problems of tube-type ozone generators that occurred during field operation.

Therefore, the present invention to solve the above problems includes a high voltage terminal box, 24 Set discharge cells, oxygen pipeline, ozone pipeline, cooling water supply pipe, and cooling water return pipe. It is composed of a pipe, a generator support, etc. The volume of the ozone generating device is small, the power consumption is low while the ozone production and concentration are high, and product performance can be expected to improve by being compact and modular. The purpose is to provide a very safe and stable plate module type ozone generator that includes functions and can monitor and operate the status of the generator on-site or remotely through the display in real time.

The present invention for achieving the above purpose is

In the oxygen and ozone pipes and cooling system, n-group parallel high-pressure discharge units are installed between the front and rear supports of the generator support, and high-pressure discharge cells are installed and connected on top of the n-group high-pressure discharge units. Each high-pressure discharge cell is fixed to the top of each group of high-pressure discharge cells by a fixed bracket. Install m number of coolant pipe prefixes at the top of the discharge cell, connect each coolant pipe to the top of the coolant pipe of n/m layer (n divided by m), connect the end to the main coolant, and circulate the internal coolant. constitutes. The horizontally installed main oxygen pipe and main ozone pipe are located between the n-group high-pressure discharge unit, the cooling water pipe, and the cooling water outlet. M cooling branch connections are formed at the top of the water intake pipe, and each connection is connected to the first end of the cooling outlet pipe of the n/m layer (n divided by m) forming the circulation of the cooling water. The first end is connected to the feed gas, and the opposite end has a p branch connecting the n/p (n division p) group and the opposite side of the high-pressure discharge cell. Circulation in the air is created by connecting the Feed Gas Pipe and the Ojo Pipe, and n, m, and p are all positive integers.

The oxygen branch uses PTFE hoses and consists of quick joints on each PTFE hose.

The front and rear supports of the generator are rail-type, and the lower part of the generator is equipped with V-shaped wheels, making installation and disassembly easy.

According to the present invention, the volume of the ozone generating device is very small compared to the existing tube method, the power consumption is low while the ozone production and concentration are high, the non-pressure container includes explosion-proof and flame retardant functions, and the on-site display is provided in real time through a display. Alternatively, the status of the generator can be monitored and operated remotely, enabling very safe and stable operation.

It is characterized by being configured to ensure internal circulation of airflow by connecting the engine and escape pipe. (However, n, m, and p are all positive integers.)

In addition, the oxygen branch pipe adopts a PTFE flexible pipe, and a quick coupling is installed in each PTFE flexible pipe.

In addition, the stand is installed on a V-shaped pulley before and after the generator at the bottom of the generator front support assembly and the rear support assembly, and is installed on the stand cap plate.

Reference numeral 4 is the generator rear support structure, reference numeral 5 is the oxygen pipeline group, and reference numeral 6 is ozone. The assembly sequence is to first install 24 sets of discharge cell modules on the support structures at the front and rear ends of the generator, and then install the oxygen pipeline and ozone pipeline as shown in Figure 1.

The 24 Set discharge cell module indicated by reference numeral 1 in Figure 1 is a key component of the entire ozone generator. Corona discharge occurs inside the module, and is divided into 8 independent discharge channel units in the 24 Set discharge cell module. The pneumatic pressure of all independent discharge channel units pushes ozone gas into the ozone main pipe through internal serial connection and pneumatic seal fitting. . Since all ozone generation through internal corona discharge is completed inside the discharge space sealed in several stages, there is no need for a separate sealing interface, fundamentally solving the sealing problem of the ozone generator, which was a difficult problem with the tube type.

The high-pressure pipe tool is connected to 23 groups, and there is a high-pressure fuse in the discharge space. When a short circuit occurs, the high-pressure fuse melts and blows immediately, so it does not affect the safety of the generator. The high-voltage electrode box 12 includes a high-voltage fuse, pipe tool, fixing plate, and ammeter display assembly placed inside the box, and all high-voltage parts are sealed through a cap plate.

Figure 6 shows the overall system of the coolant inlet pipe circuit. The coolant inlet pipe circuit is composed of coolant inlet pipe 15, coolant pipe quick fitting pipe 16, coolant cutoff pipe 17, coolant pipe quick T-type joint pipe 18, and high temperature resistant coolant hose 19. . All seals are sealed with O-ring seals and quick fittings. 16The coolant water pipe inlet pipe protrusions are evenly located at each outlet to match the flow rate and traffic implementing all outlets, and the aluminum magnesium titanium alloy material surface is adopted to prevent corrosion, and the coolant water pipeline connection adopts O-ring sealing. This allows for easy maintenance, inspection and repair while achieving complete sealing. The pressure and traffic at all eight cooling water inlets are the same, so the flow rate is consistent, and when connected to the 24 discharge cell cooling water channels, excellent cooling effects are achieved.

As shown in Figure 7, the oxygen pipeline assembly is composed of oxygen main pipes 22 and 23 and an oxygen main pipe connector 24, and is sealed through a plastic O-ring method. The oxygen main pipe (22) is made of aluminum alloy to prevent corrosion.

The ozone pipeline consists of an oxygen main pipe (21) (23) and an oxygen main pipe connector (24), and sealing is achieved through a threaded O-type plastic ring method.

As shown in FIG. 7, the stand assembly is composed of a stand 28 before and after the generator, a stand cap plate 29, and a V-shaped wheel pulley assembly 27.

The front and rear support structures can all fix the generator, high-voltage electrode cables and coolant pipelines. The front and rear support assemblies have a pulley scroll function and are combined with the track of the fixed generator, making it very easy to move, install, inspect and repair.

At the same time, the assembly is made of a semi-open U-shaped aluminum alloy material and has been subjected to special surface treatment to prevent corrosion.
