Description

Fine bubble generating device for vehicle equipped fine bubble washing apparatus for calcium chloride and fine dust removal on road facilities}

The present invention relates to a micro-bubble generating device, more specifically, to remove the calcium chloride used in roads, bridges, tunnels, etc. (hereinafter referred to as road facilities) to improve the corrosion prevention and durability of structures and to cause air pollution. The present invention relates to a microbubble generating device for a vehicle-mounted microbubble cleaning device for removing calcium chloride and fine dust from road facilities that can effectively remove fine dust (PM10).

Road facilities (roads, bridges, soundproof walls, tunnels, etc.) are particulate matter (fine dust), organic materials (nutrient salts), tire wear materials, oils, lubricants, aromatic hydrocarbon compounds (PAHs), heavy metals, etc. Various pollutants such as pathogenic microorganisms and calcium chloride exist, and municipalities including road construction are periodically cleaned.

According to the cleaning efficiency of these pollutants, it affects the maintenance cost of water usage, working hours, manpower, etc., and the damage, aging and recovery costs of road and bridge-related structures are determined according to the level of desalination.

In particular, when looking at the salt concentration of calcium chloride for snow removal purposes measured in a bridge structure, 5 to 25 g/m2 is distributed, and a salt concentration of 30 to 70 mg/L is measured at the pier side. The serious damage caused by calcium chloride is the spalling/porthole of the road, and the cost of repairing the road is higher than the annual cost of spraying calcium chloride for snow removal, and pier/vehicle corrosion is causing a very serious safety problem.

In particular, in winter, the water that is standing freezes and begins to crack gold in the structural material. When a freeze-preventing agent such as calcium chloride is used to dissolve the salt, the salt rapidly accelerates corrosion. When the salinity concentration reaches the limit, the concrete part is seriously damaged, and in addition, river water flowing from below can crush the pier and the foundation of the pier little by little, causing collapse of the pier.

Calcium chloride, which has the most influence on corrosion and aging of road, bridge, and tunnel structures, according to data from the 2013 Fire and Disaster Prevention Agency, the amount of snow removal used by local governments, the National Land Administration and the Korea Highway Corporation is 500,000,509 tons, and 30,000 tons of 15 ton dump truck It is about 3767 units. Considering private consumption, it appears that a larger amount of snow-removing agent was used.

According to the Korea Highway Corporation data in 2017, to remove calcium chloride, we carried out sprinkling work on major structures on national highways such as bridge railings, barriers, drains, and high-volume joints. .

Currently, there are periodic road cleaning and dust removal calcium chloride cleaning methods by pure manpower, wet cleaning method using a fixed sprinkling device, and wet cleaning method using a water cleaning vehicle. It can be divided into a high-pressure sprinkler with the function of spraying water at high pressure, a brush-sprinkler equipped with a brush, and a vacuum-suction sprinkler that sucks the sprayed water.

The pH of calcium chloride used for snow removal is about 11, and it has a relatively strong strong basicity compared to pH 7~8 of ordinary calcium chloride, which greatly affects the corrosion of the structure, so it is used for snow removal and effectively removes the remaining calcium chloride There is an urgent need for a method for this.

Currently, high-pressure water jet cleaning equipment is used to prevent corrosion and durability of structures by removing calcium chloride used for roads, bridges, tunnels, etc., and to effectively remove particulate matter (PM10) that causes air pollution. There is a problem and the cleaning efficiency is poor, so a new type of vehicle-mounted micro-bubble cleaning device is required.

Accordingly, the present invention was devised to solve the problems described above, and removes calcium chloride used for roads, bridges, tunnels, etc., thereby improving corrosion prevention and durability of structures and effectively controlling air pollution-causing particulate matter (PM10). An object of the present invention is to provide a microbubble generating device for a microbubble washing device equipped with a removable amount.

Figure 2 is a block diagram of the primary rotating shear mixer agitator, forming a primary bubble of 20 ~ 50㎛.

To this end, the rotary stirrer mixer stirrer 100 according to the present invention includes a rotor 10 rotated by a motor and a stator 20 coupled against the rotor.

The rotor 10 includes a first rotor 2 and a second rotor 4 protruding from the upper surface in a disc shape. The first rotor 2 is formed to protrude in a circular shape on the upper surface of the disc, and a slit 1 through which bubbles are penetrated at regular intervals is formed.

In addition, the second rotor 4 is formed to protrude in a circular shape on the original plate like the first rotor, but is configured to surround the first rotor 2 from the outside, similarly, a slit through which air bubbles penetrate at regular intervals (3) is formed.

The stator 20 is disposed to face the rotor, and the first stator 6 and the second stator 8 arranged in a circle are protruded on the disk. The first stator 6 and the second stator 8 are also formed with slits 5 and 7 at regular intervals to allow air bubbles to pass therethrough.

The first stator 6 is opposed to be disposed between the primary rotor 2 and the secondary rotor 4 constituting the rotor, and the second stator 8 is disposed outside the secondary rotor 4 To provide a passage for air bubbles.

As described above, the rotary shear mixer stirrer 100 according to the present invention is mixed with water introduced into the center and gas entering the inlet, and bubbles are destroyed while passing through the slit 1 of the rotating first rotor, and the first It is discharged through the slit 5 of the stator 6.

As the water containing bubbles passing through the slit 5 enters the slit 3 of the rotating second rotor, the bubbles are further destroyed and become finer bubbles. Through this process, it becomes a microbubble of 20-50 μm and is discharged through the slit 7 of the second stator 8.

3 is a configuration diagram of a vortex multi-stage collision plate 200 according to the present invention. The vortex multi-stage collision plate 200 according to the present invention is disposed such that the disk-shaped primary collision plate 210 and the secondary collision plate 220 face each other.

The primary collision plate 210 is formed with a slit 211 and a collision surface 212 formed at regular intervals. The microbubbles supplied from the rotary shear mixer stirrer 100 of the front end through the slit 211 partly collide with the collision surface 212, and some pass through the slit 211, and the slit 211 The microbubbles that have passed are again introduced into the secondary collision plate 220 at the rear end.

The secondary collision plate 220 is also formed with slits 221 and collision surfaces 222 formed at regular intervals. However, the secondary collision plate 220 is characterized in that the primary collision plate 210, the slit and the collision surface are arranged so that they are out of order. Therefore, the microbubbles that have passed through the slit 211 of the primary collision plate 210 are crushed to a finer size by hitting the collision surface 222 of the secondary collision plate 220, and the crushed microbubbles are slit ( It is discharged through 221) and becomes a secondary microbubble of 1~20㎛ size.

The rotating collision collapsing nozzle 300 according to the present invention is characterized by a multi-stage pipe structure composed of a plurality of pipes 320 connected to a joint 310.

For each pipe, the protrusions 321 are formed to be offset from each other so as to interfere with the flow of the fluid inside, and the fluid is rotated to cause collision, so that the bubbles collapse.

For example, in the first pipe, the inner cross section has projections formed on the upper and lower surfaces in the longitudinal direction as shown in FIG. 4(a), and the second pipe connected to the joint has a hollow portion of the pipe as shown in (b). While partitioned in half with a partition wall, a cylinder having a circular cross section in the center may extend in the longitudinal direction, and the third pipe is formed such that (5) five projections on the inner surface of the pipe extend at regular intervals in the longitudinal direction. It is a structure, and the fourth pipe may be a structure formed such that four protrusions on the inner surface of the pipe extend at regular intervals in the longitudinal direction as shown in (d).

According to the configuration as described above, the microbubbles are further crushed by the protrusion structure formed on the inner or inner surface until the secondary microbubbles having a size of 1 to 20 μm enter the first pipe and sequentially penetrate to the fourth pipe. As a result, an ultrafine bubble having a size of 100 nm to 20 μm can be obtained.

As described above, the micro-bubble washing device including the micro-bubble generating device 100 according to the present invention can be manufactured in a vehicle-mountable form to ensure mobility, so that it can be moved anywhere where calcium chloride or fine dust removal is required. By removing the calcium chloride and fine dust, it provides an effective means to prevent corrosion and improve the corrosion and durability of the structure.
