Description

Air Pollution Prevention Facility of Vehicle Paint Booth

The present invention is a prevention facility for vehicle painting booths, and if this is explained in more detail, it is intended to more efficiently filter and discharge dust and odors generated from painting booths that paint vehicles.

When painting the exterior of a vehicle, painting is performed at the painting booth. Depending on the painting range, a spray is used or an air gun connected to a compressor is used.

It is important to remove the odor of the paint and dust containing volatile organic compounds generated when the paint is sprayed from the paint booth for air conditioning inside the painting booth and a comfortable working environment for the worker.

Since substances that may pollute the atmosphere cannot be discharged to the outside in accordance with the Air Conservation Act determined by the Ordinance of the Ministry of Environment, a prevention facility must be installed to filter the dust and odor of the fluid inside the painting booth and discharge it to the outside. .

As published in Korean Registered Patent No. 1225624 (announced on January 24, 2013), in a device that controls the supply and discharge of air in the painting and drying process of automobiles, an insulation panel is provided above the underground exhaust, A booth providing direct fire with a gas burner; Air supply means connected to one side of the booth through a plurality of filters and including an air supply fan driven by an inverter motor; Exhaust means connected to the other side of the booth via a plurality of filters and including an exhaust fan driven by an inverter motor; And a controller for controlling the air supply means and the exhaust means in response to the process of performing the drying, wherein the technology is developed by discharging air to the lower part of the vehicle by an exhaust fan. This is a description of the composition of a general painting booth prevention facility configured to be filtered by an exhaust filter.

As published in Republic of Korea Patent Publication No.0014186 (published on February 15, 2003), volatile organic compounds generated from automobile painting booths are adsorbed and removed with an activated carbon filter to suppress the emission of pollutants. By raising the temperature of the activated carbon filter to desorb volatile organic compounds and then decomposing and removing them in the microbial processor, the operating life of the activated carbon filter can be extended from 3 months to 1 year. In addition, the treatment device is installed in the filter part and the intake part. It relates to a device for treating volatile organic compounds in automobile painting facilities, which can be assembled and installed regardless of the installation of the existing painting booth by separating into an exhaust part and convenient transport. In particular, volatile organic compounds are absorbed by an activated carbon filter. In the volatile organic compound treatment device of the automobile painting facility, which is designed for desorption removal and regeneration operation, a perforated plate is attached to the front of the intake air so that volatile organic compounds and harmful dust can evenly flow into the entire filter area. To prevent contaminated air from flowing into the purified air (over-flow), a specially structured pre-treatment filter, intermediate filter, and zeolite filter are stacked, respectively, placed above the intake and intake parts that adsorb harmful dust, followed by volatile organic compounds. Two activated carbon filters that adsorb substances are in a group, and the flow area is adjusted in a way that they are installed opposite to each other in a triangular structure with a wide bottom and a narrow top, so that the flow is uniformly introduced to the front of the filter. In order to prevent unpurified air from leaking out of the activated carbon filter, each activated carbon filter is equipped with a presser to maintain airtightness, and the activated carbon is heated by using a heater between these filters to desorb and desorb volatile organic compounds. A technology has been developed to suppress the emission of pollutants by decomposing and removing the volatile organic compounds in a microbial processor.

However, in the above technology, an activated carbon filter for removing odors is formed in a mountain shape, and in the known general technology, the activated carbon filter is configured in a horizontal plane or mountain-type arrangement, and in reality, the area through which dust and odors pass is small, so the life of the filter is short. There was a problem that the period was also shortened and the maintenance cost increased.

Since the amount of air blown to the space of the prevention facilities installed by each company was different, there was also inconvenience in customizing the ventilation facilities that fit the space.

The present invention is intended to provide a prevention facility for a vehicle painting booth, and this will be described in more detail with the drawings below, and the accompanying drawings are only examples for easily explaining the content and scope of the technical idea of the present invention. This is not limited thereto, and the terms used are also intended to specifically describe the embodiments, and are limited to the corresponding terms and should not be interpreted.

As shown in the drawings, the prevention facility of the vehicle painting booth of the present invention communicates with the vehicle painting booth 100 to discharge dust and odors from the vehicle painting booth 100 to the outside, and It includes a filtering means 3 consisting of a dust filter 31 interposed between the vehicle painting booth 100 and the blowing means 4 to collect dust, and an activated carbon filter 32 for collecting odors, and an activated carbon filter ( 32) is an upper blocking portion (32a) formed to induce the flow of fluid to the side, a standing filtration unit (32b) that is coupled to the lower portion of the upper blocking unit (32a) to form a closed curve in a plane, and a standing filtration unit (32b) A support plate 32e formed with an opening 32c formed to allow fluid to be introduced into the lower portion of the panel, and a support plate to communicate air in correspondence with the support plate 32e in which the activated carbon filter 32 is placed, and the opening 32c of the activated carbon filter 32 Characterized in that the communication hole (32f) formed in (32e) is further included.

In addition, the dust filter 31 includes one or more of the Andrea filter 31a or the pre-filter 31b, and a carbon filter that collects dust and harmful gases from the top of the Andrea filter 31a or the pre-filter 31b (31c) may be characterized in that it is further included.

In addition, the upper blocking portion 32a is formed to be inclined laterally to the vertical guide portion 32a-1 formed to extend downwardly to the lower portion of the upper blocking portion 32a, and is formed to be inclined laterally to the opening 32c. The induction guide part 32a-2 formed to guide the incoming air to the standing filtration part 32b, and the standing filtration part without air from reaching the upper blocking part 32a from the uppermost induction guide part 32a-2. It further comprises a blocking guide part (32a-3) for guiding to be transferred to 32b) and a guide inlet part (32a-4) through which air is introduced into the guide guide part (32a-2), and communication between the support plate (32e) The ball (32f) is formed in a size corresponding to the guide inlet (32a-4), characterized in that it reduces the pressure loss inside the activated carbon filter (32) to reduce the power consumption of the blowing means (4). When coupling the blocking part 32a to the standing filtration part 32b, the gap part 32a-5 can be further configured so that the outside of the vertical guide part 32a-1 does not interfere with the inside of the standing filtration part 32b. The gap portion 32a-5 is preferably narrower in order to increase the guide efficiency.

In addition, a speed control unit 43 for controlling the number of revolutions of the blowing means 4 and a sensor 42 for measuring the internal pressure of the vehicle painting booth 100 are further included, and blowing according to the internal pressure of the vehicle painting booth 100 It may be characterized in that the air volume of the means (4) is adjusted to correspond to the filtering power of the filter.

Looking at the above configuration in more detail with the action are as follows.

As shown in Fig. 1, the vehicle painting booth 100 improves the health and work efficiency of the worker, and the dust and smell floating in the air generated from the paint sprayed on the vehicle to improve the painting quality of the painting object 102 Including volatile organic compounds, it is necessary to discharge foreign substances that are harmful to the human body and deteriorate the quality of painting.

The foreign matter must be purified and discharged outdoors according to the Air Environment Conservation Act determined by the Ordinance of the Ministry of Environment.

Therefore, on one side of the vehicle painting booth 100, a prevention facility 1 communicated with the suction port 2 is installed.

Since the internal air of the vehicle painting booth 100 is sucked into the prevention facility 1, the vehicle painting booth 100 is further configured such that an inlet 101 through which outside air can be introduced is interposed with an inlet filter.

The prevention facility 1 discharges the purified air to the outside through the communicated outlet 5, and may be configured such that the outlet 5 is connected to the inlet 101, not the outdoor, if necessary.

As shown in FIG. 2, the prevention facility 1 is provided with a blowing means 4 capable of forcibly transferring a fluid in order to suck in air through the inlet 2.

The blowing means 4 is composed of a motor 41 and a fan 42.

Therefore, the air is pushed out to the outside where the outlet (5) is formed in accordance with the operation of the blowing means (4), so the air inside the vehicle painting booth (100) is sucked into the prevention facility (1) through the inlet (2) due to the pressure difference. It will enter.

A filtering means 3 is interposed between the suction port 2 and the blowing means 4.

The filtering means (3) filters foreign matters such as dust and odor, and discharges the clean air to the outside through the blowing means (4).

The filtering means 3 includes an Andrea filter 31a, a prefilter 31b, a carbon filter 31c, and an activated carbon filter 32 in the order in which air passes, as shown in FIG. 3, and the Andrea filter 31a ) And the pre-filter 31b can be applied only to one or more of the two.

Andrea Filter (31a) is one of the commercially available technologies, and uses thick paper or synthetic fibers in the form of overlapping V-shapes, and collects more than 50% of paint dust.

While there is a high possibility that the filter made of non-woven fabric will be clogged by the dust of the paint, the Andrea filter 31a collects dust accumulatively, so it is possible to collect a much larger amount of dust, so the dust filtration efficiency is excellent, and the filter by the collected dust Since there is little fear of clogging, it is suitable for use as the primary dust filter 31.

Pre Filter (31b) is one of the commercialized technologies made of polyester non-woven fabric. It is a filter that filters dust of a smaller size than the dust collected by Andrea filter (31a). Can be filtered.

However, the pre-filter 31b has a high risk of obstructing the fluid flow of the blowing means 4 due to clogging of air gaps by dust, so that the filtering unit area is formed to have a long life.

The pre-filter 31b is suitable for use as a secondary dust filter 31 following the Andrea filter 31a, and according to the amount of dust to be filtered according to the amount of paint used in the vehicle painting booth 100, the Andrea filter 31a It can also be used as the primary dust filter 31 without.

The existing prevention facility 1 constitutes at least one of the Andrea filter 31a and the pre-filter 31b to collect dust, but the paint dust is not properly filtered and reaches the activated carbon filter 32 to reach the activated carbon filter ( When dust adheres to the surface of 32), the filtering efficiency of activated carbon decreases rapidly, so it is important to properly filter the dust in the dust filtering means (3).

Therefore, in the present invention, a carbon filter 31c may be additionally interposed between the dust filter 31 and the activated carbon filter 32 of the Andrea filter 31a and the prefilter 31b.

The carbon filter 31c is manufactured by impregnating polyester carbon and has a collection rate of about 20%.

Following the Andrea filter 31a and the pre-filter 31b, it acts as a third dust filter 31, and has a function of removing some odors and harmful gases in addition to dust.

Air passing through the dust filter 31 composed of the Andrea filter 31a, the pre-filter 31b, and the carbon filter 31c is then passed through the activated carbon filter 32 made of activated carbon.

Conventionally, the activated carbon filter 32 has been formed in a horizontal or mountain shape, but in this case, there is a problem in that the active carbon area is relatively small and the replacement cycle is short.

Thus, in the present invention, the shape of the activated carbon filter 32 is formed to guide the flow of fluid to the side, the upper blocking part 32a, the standing filtration part 32b coupled to the lower part of the upper blocking part 32a, and the standing filtration It was configured with an opening 32c formed to allow fluid to be introduced into the lower portion of the portion 32b.

The standing filtration unit 32b has a shape of any one of various polygonal shapes such as a circular shape, a triangular shape, or a square shape, or a hexagonal shape when viewed in plan to form a closed curve.

An upper blocking portion 32a is coupled to the upper part of the standing filter unit 32b so that the upper part is closed according to the shape of a closed curve formed by the standing filter unit 32b.

An opening 32c with an empty inside is naturally formed under the standing filtration unit 32b according to the shape of a closed curve formed by the standing filtration unit 32b, and the opening 32c also serves to closely adhere to the dust filter 31. .

Therefore, the air that has passed through the dust filter 31 is introduced into the opening 32c of the standing filter unit 32b, is guided to the side by the blocked upper blocking unit 32a, and is formed in the standing filter unit 32b. It is filtered while passing through and removes odors, dust and harmful gases by adsorption of hydrocarbons floating in the air.

Compared to the conventional mountain type or horizontal type, since the filter is formed in an erected shape in all directions, the cross-sectional area where filtration is performed is substantially larger, so that the life of the filter is extended, and the amount of air that can be filtered at one time is also increased.

The activated carbon filters 32 are configured such that several are spaced apart from each other by a predetermined distance, and each activated carbon filter may be fixed in close contact with the uppermost filter of the dust filters 31.

The space between the activated carbon filter 32 is separated from the activated carbon filter 32 in order to prevent the air passing through the dust filter 31 from being discharged without passing through the activated carbon filter 32. ) May be further configured, or the dust filter 31 may be formed to correspond to the size of the activated carbon filter 32.

The separation cut-off part 32d is configured such that a separate support plate 32e is interposed between the activated carbon filter 32 and the dust filter 31, so that the activated carbon filter 32 is coupled to the support plate 32e. In addition, a communication hole 32f is formed in the support plate 32e so as to correspond to the opening 32c of the activated carbon filter 32.

As shown in FIG. 4, the activated carbon filters 32 spaced apart from each other can be configured in various ways as necessary.

As shown in (b) of FIG. 4, the standing filtration part 32b of the activated carbon filter 32 may be formed in a circular or arc shape without an angle, and several may be arranged.

As shown in Fig. 4 (a), (c), and (d), the standing filtration unit 32b of the activated carbon filter 32 may be formed in a polygonal shape and several may be arranged.

In addition, as shown in FIG. 5, an induction guide 32a-2 may be further installed under the upper blocking portion 32a.

At least one pair of plates is installed to be symmetrically inclined in an oblique line, so that the air flowing in through the opening 32c reaches the upper blocking portion 32a, and the air is erected by the induction guide 32a-1. Is to induce them to be transferred to.

Therefore, it is possible to reduce the pressure loss because the filtration proceeds even if the inflowed air does not fill the inside of the activated carbon filter 32 until it reaches the upper blocking part 32a. Therefore, the filtration can be performed even with low-speed blowing. Since the output of the device can be reduced, it is expected to reduce the maintenance cost due to low power.

The air purified by passing through the filtering means 3 consisting of the dust filter 31 and the activated carbon filter 32 is transferred to the blowing means 4.

The blowing means (4) is composed of a motor (41) and a fan (42) and serves to push the air toward the outlet (5).

The fan 42 also responds to this by a constant rotational force of the motor 41 and has a constant blowing force.

In addition, a speed control unit 43 such as an inverter that adjusts the rotational force may be added to the motor 41.

A lot of foreign matter such as dust accumulates in the filters of the filtering means 3 to reduce the filtering power, and as the life of the filter decreases, the amount of air passing through the filter decreases.

Therefore, since positive pressure is generated in the vehicle painting booth 100, a separate sensor 42 can be installed inside the vehicle painting booth 100 to detect the pressure.

According to the pressure detected by the sensor 42, when positive pressure is detected in the vehicle painting booth 100, the air inside the vehicle painting booth 100 cannot be properly discharged, so the rotational force of the motor 41 through the speed control unit 43 Increased to induce forced exhaust.

When a negative pressure is detected in the vehicle painting booth 100, the blowing force is relatively too strong, so that the rotational force of the motor 41 is automatically lowered through the speed control unit 43.

If the internal pressure of the vehicle painting booth 100 is not lowered even though the positive pressure is detected in the vehicle painting booth 100 and the rotational force of the motor 41 is increased by the speed control unit 43, the life of the filter has arrived. It is possible to additionally provide a separate notification means to determine and notify the user of the replacement warning.

If the filter is clogged with paint dust or the like, the air inside the vehicle painting booth 100 may not circulate properly, which may eventually deteriorate the painting quality, which can be prevented in advance.

In addition, even if the motor 41 of the blowing means 4 is not suitable for the volume of the vehicle painting booth 100, the speed control unit 43 is operated according to the internal pressure of the vehicle painting booth 100 Since it is possible to appropriately adjust the blowing force of (41), it is possible to increase the compatibility of the motor 41 for various vehicle painting booths 100.

As described above, in the detailed description of the present invention, the most preferred embodiment of the present invention has been described, but various modifications are possible within the scope not departing from the technical scope of the present invention. Therefore, the scope of protection of the present invention is not limited to the above embodiments, but the scope of protection should be recognized from the techniques of the claims to be described later and from these techniques to equivalent technical means.
