Description

Mist collecting device using thermoelectric device {omitted}

The present invention relates to a mist collecting device using a thermoelectric element. In general industry, oil and water mist (MIST) is discharged into the factory or into the atmosphere, and this is achieved by physical methods such as centrifugal force, cohesion force, and adsorption force by using impeller, screw propeller, and filter. There is a device that separates oil and water mist into air and liquid (water oil) and collects and removes them.In general, when oil and water mist is discharged into a factory or air, problems such as worker health and air pollution in working environment In order to improve, the mist elimination device using a filter is used.

According to the prior art described in FIG. 5, the oil-soluble mist passed through the suction port by the rotation of the impeller is sucked into the drum, and passes through the drum filter attached to the inner surface of the drum to make the fine particles of the water-soluble mist into large particles. By the way, the fumes filtered by air and liquid pass through the filter through the inside of the outer cylinder, and the oil and water-soluble fumes are separated into the collecting liquid and the air, and the air is discharged through the air outlet, and the collecting liquid is discharged through the liquid outlet. There is a water-soluble mist elimination device for discharging, and the conventional technique is a drum filter and a filter, and the problem that occurs when separating the oil-soluble mist into air and the collecting liquid is the first water-soluble mist passed through the drum filter and filter. While the filter hole is clogged, the filter's function decreases, which reduces the ability to remove oil and water mist. Is the exchange cycle of the filter shortened dream has environmental problems are caused, such as degrading the operation of the high consumption of the filter much maintenance costs third machine and waste treatment of waste filter. In order to solve the problems described above, the collecting device, which was previously filed by me, is a screw propeller method of screw propeller method rather than a filter method for separating oil and water-soluble fumes into air and collecting liquid. As the oil-soluble mist passes through the groove (space) between the spiral screw propeller and the screw propeller, the oil / water-soluble mist uses the natural physical properties such as centrifugal force, cohesion force, and adhesion force. During repeated rotations, the water-soluble mist is made into large particles, and the oil-soluble mist is separated into air and the collecting liquid. Most of the oil and water-soluble fumes remaining after the air is separated into the collecting liquid pass through the SAFETY FILTER, are separated into air and the collecting liquid, and the air is discharged to the atmosphere through the air outlet, and the collecting liquid is discharged through the liquid outlet. Discharged. That is, an inlet and an air outlet are formed in front and rear surfaces, an outer cylinder having a liquid discharge hole formed therein, an inner cylinder installed concentrically with the outer cylinder inside the outer cylinder, and an impeller installed in front of the inner cylinder; It is connected to the rear of the impeller is installed in the inner cylinder is composed of a motor for driving the impeller, a screw propeller is installed in a plurality of spiral on the cylindrical outer surface of the inner cylinder, between the inner cylinder and the motor There is an industrial oil- and water-soluble mist elimination device installed with a cylindrical safety filter in the inner cylinder and concentric shape.

In more detail, the process of separating and removing the water-soluble mist is carried out by the operation of the motor, and the oil-water-soluble mist is sucked through the suction port while the impeller, which is the mist suction unit (A), rotates and passes through the impeller and then is sucked into the mist separator (B). do. The sucked oil-soluble mist passes through the outer cylinder, the inner cylinder, the screw propeller, and the safety filter of the mist separation unit (B), and is separated into the collecting liquid and the air.

At this time, the principle of separating water-soluble mist into collecting liquid and air is based on the spiral space between the outer cylinder, the inner cylinder and the spiral screw propeller by the rotation of the impeller. Using the inherent physical properties of oil-soluble mists, such as centrifugal force, cohesive force, and adhesive force, the oil-water-soluble mists are naturally separated into the collecting liquid and air, respectively. When rotating in the direction from the standard, the air proceeds while rotating in the direction, but the particles of oil-soluble mist and water oil collide with the inner surface or the point of the outer cylinder by centrifugal force and collide with each other. The collected liquid is discharged through the liquid outlet port along the inner surface of the outer cylinder.

As shown in FIG. 1 again, the liquid mist containing the liquid mist contained in the air while passing through the helical groove of the screw propeller passes through the safety filter. It is completely separated into air and collecting liquid.

The separated air is discharged through the air outlet to the atmosphere, and the collected liquid is collected through the liquid outlet to be collected or reused.

As described in detail above, the above-described invention of the present application uses a spiral screw propeller and a filter to completely separate and remove oil-water-soluble fumes into the collecting liquid and air, and thus to work conditions of the worker and the atmospheric environment. In addition, the helical screw propeller device and the liquid mist can be removed by separating the oil-water-soluble mist into air and liquid by using the physical properties of the centrifugal cohesion force. The cost and time of replacement can be reduced, and the screw propeller method can maintain semi-permanent life as there is almost no filter replacement.

Oil- and water-soluble mist (MIST) removal device is composed of a mist inlet (A), mist separation (B), air discharge (C), liquid discharge (D), the mist intake (A) is an impeller The mist is sucked by the rotation of (IMPELLER), and the mist separation part (B) is a centrifugal force for the water-soluble mist (MIST) while the mist rotates at a high speed along the spiral groove (space) of the spiral screw propeller (SCREWPROPELLER). Separating fumes and air naturally by using physical fluid engineering methods such as cohesion and adhesion, and filtering the fumes of the remaining liquid with a filter to completely separate the fumes into air and liquid, and the air discharge unit ( C) is a step of discharging the separated air through the air outlet, the liquid discharge unit (D) is a skew propeller characterized in that the step of discharging the collected liquid separated into air and liquid in the oil-soluble mist (SCREW PROPELL It is oil-soluble mist elimination device with ER) method.

However, the biggest feature of mist and water vapor is that it is a particulate but liquid.

Therefore, the latest collection device currently developed and used at home and abroad is a collecting device for agglomerated liquid fine particles to separate each other into large particles and air. However, the biggest drawback and limitation of this collection device is that it is impossible to collect at high temperatures (40 ° C is specified in the specification as almost all manufacturers), and there is a drawback that the collection efficiency varies greatly depending on the temperature. .

The present invention has been made to solve the problems as described above,

The thermoelectric element is used to reduce the temperature of water-soluble mists and the like to inhibit the activation of these materials to increase the surface tension and to make them stick together.

In general, oil and water mist generated during machining and working using lathes, water vapor containing contaminants generated during heat treatment and washing operations, and water vapor generated in the food industry are exposed to workplaces and workers, It leads to safety problems, workplace health and environmental problems, and thus industrial safety and environmental problems and productivity decreases.

Hazardous substances, such as water-soluble mists, adversely affect workers' respiratory organs and lungs when exposed to workers, and because their properties are floating liquids with appropriate temperatures, they create an environment suitable for microbial habitat in air conditioners and piping, and spread them throughout the workplace. It causes health and environmental problems, and it can also be the cause of failure of sensitive electronic devices such as precision machinery.It can also settle on the floor of the workplace and make the floor slippery, which can cause safety accidents. Since more is generated more, the productivity is reduced due to the adjustment of the working speed accordingly.

In order to solve this problem, the industry uses a collection device using various methods. These are devices of the method for collecting general particulates according to the property that mist and water vapor are aerodynamically particulate matter.

However, the biggest feature of mist and water vapor is that it is particulate but liquid.

Therefore, the latest collection device currently developed and used at home and abroad is a collecting device for agglomerated liquid fine particles to separate each other into large particles and air. However, the biggest drawback and limitation of this collection device is that it is impossible to collect at high temperatures (40 ° C is specified in the specification as almost all manufacturers), and there is a drawback that the collection efficiency varies greatly depending on the temperature. .

Procedural description of the collection method by the collecting device of the present invention that improved this is as follows.

Inhalation (contaminated air with constant temperature mist and water vapor) → Rectification (keep the flow of air through constant) → Cooling (make the temperature required for passing air) → Condensation (liquid mist, water vapor Exhaust large particles) → Exhaust (Exhaust cooled air or send to next collector)

The configuration of the present invention is composed of a rectifying plate, a cooling plate, etc. If described in detail as follows. First, the rectifying plate, which is one of the main components of the present invention, is a perforated plate which is located between the inlet and the cooling plate, and has a hole smaller than the gap of the cooling plate, and the main function of uniformly introducing the air entering the inlet into the next cooling plate. It also functions as a filter to protect the cold plate.

The cooling plate is located in the center of the main body after the rectifying plate and uses a metal material with excellent thermal conductivity such as aluminum. Its function is to cool the required temperature of inlet air, including high temperature mists, water vapor, etc. In addition to the main cooling function, it collects by inertia and collision.

The heat sink is located in the heat generating part of the outer thermoelectric element of the dual structure body, and uses a metal material having excellent thermal conductivity such as aluminum. Its function protects the thermoelectric element from overheating, thus maximizing its lifetime and function.

The heat dissipation method is forced air cooling, and the surrounding air is sucked through the main heat inlet and the other air inlet.

The liquid discharge port is located at the inner end of the main body and the front of the air discharge port formed of a double structure of the outer cylinder and the inner cylinder, and the material is installed in the same pipe as the main material. Its function is to separate and discharge the liquid collected in the cooling plate due to cohesion or inertia and collision to prevent it from passing outside.

Thermoelectric element is a next-generation cooling method that replaces the existing compressor cooling method that can achieve cooling, heating, and power generation only by supplying DC power by using heat transfer material. The object can be kept at a constant temperature by cooling and heating from -30 ° C to +150 ° C.

1930-Russian scientists begin research on rural electricity supply and power generation

1950-ALOFFE and his team: Research and practical application of technology improvement of semiconductor materials. Through this process, it is currently being commercialized and commercialized in the areas of cooling, heat generation and power generation.

Advantages and disadvantages of thermoelectric elements include miniaturization, ease of installation, easy cooling, simultaneous heating cooling, precision temperature, control function, high reliability, low noise, zero gravity operation, simple power supply, local cooling, replacement of thermal power generation, environmentally friendly Mars. Its disadvantage is the use of direct current power supplies and overheating measures. One of the features of the mist collecting device using the thermoelectric element of the present invention is a cooling function, the liquid fine particles having an irregular temperature such as oil, water-soluble mist, water vapor, etc. to be collected by the device have a cohesive force which is a pulling force between the molecules constituting them. Maximize and condense to collect. Condensation, a phenomenon in which a gas turns into a liquid, occurs when it is cooled at a certain pressure and lowered below a certain temperature, or when pressure is applied at a constant temperature to exceed the saturated vapor pressure of the material. The device is a way of causing condensation to occur by cooling. Another aspect of the present invention relates to a collision trapping cold plate device, which has made the contact surface of the inlet air cooler to maximize the cooling effect of the inlet air, and is capable of self-collecting due to inertia collision. The liquid is designed to flow down without being affected by the passage airflow.

This device is a new collection method that maximizes the efficiency by adding cooling function to the collision collecting device.

In order to capture liquid particles having irregular temperatures such as oil, water-soluble mist, and water vapor, which are the targets of the device, SURFACE TENSION, a force acting to reduce the surface of the liquid, is used. It lowers the activation of these substances and increases the surface tension to make them stick together to separate.

Another feature of the present invention is that the thermoelectric element generates heat simultaneously with cooling. Therefore, if heat is not effectively treated, this heat is transferred to the cooling plate, which lowers the cooling function, burns internal materials, contacts, etc., and leads directly to failure. Therefore, the heat dissipation function is very important in the thermoelectric element, and this apparatus solves this problem by an adjustable forced air cooling method. Collectors such as mist and water vapor are essential for absorbing them (FAN, BLOWER, etc.). This device uses this suction force to inhale the surrounding air and pass heat radiation through the heat sink. The solution is self-contained without the use of a heat sink, water (if water cooled) or complicated heat sinks. The device can be miniaturized, so that 40 x 40 mm thermoelectric elements are connected in series or in parallel, which is much smaller than existing refrigeration machines or devices. In addition, there is no noise because there is no mechanical or power unit. It is pollution-free and environmentally friendly because it uses only electricity and does not use freon gas for cooling.

On the other hand, there is a characteristic of the configuration that the cooling and heat dissipation are simultaneously performed while operating the machine to suck the mist, steam and the like. In addition, the trapping device using the thermoelectric element can be used in conjunction with the front and rear surfaces of the existing mist collecting device, simply by attaching only the thermoelectric element to the cylindrical outer surface of the existing mist collecting device, such as the present invention The mounting position can be changed wherever necessary. Therefore, in the present invention, the oil-soluble mist passing through the suction port by the rotation of the impeller passes through the drum filter attached to the inner surface of the drum after suctioning into the drum to make the fine particles of the oil-soluble mist into large particles, and the primary mist is air and liquid.
