Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a snow removal method and apparatus using high temperature water,

The present invention relates to a method and apparatus for snow removal using hot water, and more particularly, to a snow removal method and apparatus using hot water to replace a calcium chloride snow remover sprayed on a road for winter snow removal

Normally, when snow falls in the winter season and the snow falls on the road, the road surface will freeze, causing a great deal of trouble to the vehicle, as well as accidents such as vehicle accidents and pedestrian accidents. have.

In order to remove the snow on the road or to thaw the road surface, it is necessary to use a vehicle to spray the snowmelt mixed with calcium chloride and water, that is, salt water on the road, or to sand with the calcium chloride snow remover Snow removal work is being carried out to spread the friction agent on the road.

However, the method of spraying the snow remover using the moving snowmobile was not only time consuming to move the snowmobile to the place where the snow had melted, but also the snow was mixed with the rubbing agent and the road was dirty. In addition, there is a fundamental problem in snow removal of a wide area because there is a limit to the ability of the snow removal vehicle to store the snow removal agent.

In view of this, a method of performing a snow removal operation by installing a snow removal device capable of spraying the snow removal agent on both sides of the road without using a snow removal vehicle has been developed and used in recent years. Such a stationary snow removal apparatus has a predetermined effect by being installed in a region where a road is inclined to a great extent or in a region that can be greatly affected by snowfall.

However, not only does it take a considerable amount of time to mix the solid calcium chloride with water, but it is also a very difficult task to quickly produce a constant amount of snow removers that are uniformly mixed, and therefore, Spraying snow removers still has a lot of problems.

For example, Korean Patent No. 10-1245297 discloses a method for quickly producing a snow remover, i.e., brine, in which hot water and calcium chloride are rapidly mixed by heating water using a heat exchanger together with a snow remover installed in a vehicle Korean Patent No. 10-1666607 discloses a snow removal apparatus for a vehicle which mixes high temperature hot water with low temperature snow water to produce high temperature snow water. Korean Patent No. 10-1192992 discloses a salinity measuring apparatus for uniformly producing salt water based on salinity measurement of a calcium chloride solution. Korean Patent No. 10-1315020 discloses a salinity measuring apparatus for uniformly producing salt water from a tank provided with a stirring wing therein, One snow remover, a brine production system for the rapid production of brine, has been proposed.

The snow removal method using a liquid snow remover mixed with water and calcium chloride causes a problem that the saline used as a snow remover is not preferable in terms of environment in addition to a problem that it must be mixed quickly and uniformly. The calcium chloride used as a snow remover is superior to other snow removers in terms of melting performance and is used as an excellent snow remover in preparation for heavy snow. However, studies on damages caused by it are extremely limited in Korea It is true. However, since calcium chloride, which has been snow-covered, accumulates in the soil around the trees and damages the trees, it needs to be managed according to the characteristics of the trees in the trees. Considering that the amount of calcium chloride sprayed by the snow removal equipment is several tens of tons per year, Damage caused by calcium chloride can not be neglected because it has a great impact on concrete and asphalt as well as plant and soil pollution and water pollution such as trees.

Damage to the pavement caused by saltwater-based snow remover is caused by corrosion of the concrete or asphalt pavement surface, resulting in a decrease in durability. Secondary damage is the reduction in ride comfort. It can not be ignored that it accelerates corrosion by 4 to 5 times as a side effect to automobiles, roads and bridges, while it provides the advantage of absorbing and melting snow easily.

Various methods of solving this problem of calcium chloride for snow remover or reducing the damage of calcium chloride for snow remover are continuously being developed.

First, a method of using an eco-friendly material other than calcium chloride for snow remover and using it as a snow removing agent has been proposed. For example, Korean Patent No. 10-1025299 discloses a snow removal method using neutralization heat, -1168946 discloses a non-chloride-based liquid snow / snow melting composition and a snow removal / melting method, and Korean Patent No. 10-1176208 discloses an environmentally friendly calcium chloride-based liquid snow drier and a manufacturing method thereof.

However, the development of snow removers on the excellent snow-removing ability of calcium chloride has not been made yet, and since the price of the environmentally friendly snow removers developed in the meantime is remarkably different from that of calcium chloride snow removers, There are still many problems with the use of these snow removers that can be realized.

As an alternative, there are suggestions for minimizing the damage caused by the use of calcium chloride snow removers. Korean Patent No. 10-0939807 discloses a snow removal system that removes foreign matter such as snow-melting solids or chemicals left on the road after use of calcium chloride snow remover, Korean Patent No. 10-1654869 and No. 10-1702554 Two - phase flow is used to optimize spraying amount and injection range of snow remover, thereby improving the road performance and minimizing the amount of snow remover.

However, since all of these methods presuppose the use of calcium chloride snow remover, they are difficult to apply as a fundamental solution.

On the other hand, Korean Patent No. 10-1083707 discloses snow removal equipment using a water heater such as a heater and a boiler mounted on a vehicle, Korean Patent No. 10-1243352 discloses an automatic deicing mower using hot brine or hot water Korean Patent Laid-Open Publication No. 10-2014-0108847 discloses a snow removal apparatus using a fire hydrant.

These devices are realistic as a means to exclude the use of calcium chloride snow remover from the viewpoint that they are snow removers that use water heated by a vehicle or utilize water used for fire hydrants by power conversion devices, After the work was completed, the water used for snow removal did not offer an alternative to the problem of freezing in the winter, especially at night. Therefore, these snow removal apparatuses may be effective primarily in snow removal, but it is a reality that there is a fundamental problem that needs to be improved for practical use.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of a snow removal apparatus using hot water according to the present invention will be described with reference to FIGS. 1 to 6.

1 is a block diagram illustrating a snow removal method using hot water according to an embodiment of the present invention. Referring to FIG. 1, a snow removal method using hot water according to the present invention is characterized in that, Unlike the snow removal method, it does not use any snow removal system including calcium chloride or any component in the snow removal operation. This feature is achieved by using a spray line installed in the vehicle or fixedly installed along the road, The advantage of being able to fundamentally solve various problems arising from the freezing-preventing snow remover mixed with water, that is, the snow removing operation of spraying the brine on the road or spraying the rubbing agent such as sand with the snow remover on the road .

Referring to FIG. 1, as a preparation step for carrying out the snow removal method using hot water according to the present invention, a step of supplying a suitable container capable of storing a predetermined amount of water, that is, several liters (L) ≪ / RTI >

A single container may be used for this purpose, but it is not necessary to use a single container, and a plurality of containers capable of storing a predetermined amount of water at predetermined positions at appropriate intervals according to the site conditions may be used. Storing such a predetermined amount of water in a suitable container can be made in various ways in various ways.

A step of heating the water stored in the vessel immediately after snow begins to fall in the winter when water is supplied and stored in a container having a predetermined capacity is started. The heating of the water needs to be configured so as to quickly heat up to a predetermined heating temperature suitable for the optimum conditions in consideration of the predicted amount of heating, and the heating temperature is generally 80 ° C or higher, preferably 100 ° C or higher. To this end, as will be explained in more detail later, the capacity of the container for storing water needs to be optimized to such an extent that sufficient snow removal can be carried out for the anticipated snow cover.

The heating of the water can be performed in various ways, for example, by arranging a heating wire inside a container for storing water to instantaneously heat the entire water. Alternatively, a heating system may be installed at the outlet portion of the water outlet, and only the water to be discharged may be instantaneously heated. In this case, it is also possible to previously preheat the water inside the vessel storing the water to a predetermined temperature or more. This preheating system is a method in which after the previous snow removal work, Or by applying a system that maintains the temperature at a constant temperature.

It should be noted that the step of heating the water stored in the vessel to a predetermined temperature may be configured in various ways, and all of the various changes and modifications related thereto may be performed within the scope of the concept of the present invention.

Next, the step of pressurizing and transferring the water heated to the predetermined temperature to a predetermined high pressure is performed.

The method of pressurizing high temperature water is widely known as high temperature water heating or high-pressure hot-water heating, so a detailed description thereof will be omitted.

A separate pump chamber can be installed to perform this step.

The water heated to a high temperature and compressed at a high pressure is transferred to a plurality of injection means installed at a predetermined position through a transfer pipe. At this time, the transfer pipe for transferring the hot water is controlled by a control valve. It is known as a high temperature high pressure valve. The high temperature and high pressure valve material should be selected as a material which is resistant to the action of high temperature, hydrogen and oxygen and applicable to the pressure. Typically, high-temperature and high-pressure valves use chromium-molybdenum cast steels and chromium-molybdenum steels in which a small amount of titanium, vanadium, tungsten, or the like is added and the heat resistance is increased by special heat treatment.

Next, the high temperature water transferred to the predetermined position is discharged to the outside. Preferably, such high temperature water discharge is performed by spraying the high temperature water by an appropriate spraying means.

In order to more efficiently perform the spraying of the hot water, it is preferable that the spraying distance, the injection direction, and the injection amount of the hot water are controlled to be constant. In this regard, Such as the lane or width of the road, the gradient, or the turning radius of the lane, must be considered.

Further, the present invention includes a step of controlling a snow state based on an external snow removal environment in performing a snow removal operation using a snow removal system suitably designed in accordance with the concept of the present invention. The step of controlling the snow removal state needs to be controlled by inputting various parameters related to the snow removal environment, and a more detailed description thereof will be described later with reference to FIG.

When the spraying of the hot water is stopped by the step of controlling the snow state and the snow removal operation is completed, the snow remaining on the road, that is, the snow removed by the hot water, is generated by the spraying of the melted water and the hot water A step of preventing freezing of the hot water is performed so as to prevent the water from freezing on the road at a low temperature in winter.

The step of preventing freezing of the hot water can be performed in various ways, and various embodiments related thereto will now be described in detail.

According to a preferred embodiment of the present invention, the step of preventing freezing of the hot water may include a step of spraying an anti-icing agent such as an environmentally friendly snow removing agent, which does not contain calcium chloride, A method of preventing the freezing of water remaining on the road is provided.

Therefore, it is advantageous to use an eco-friendly snowmelt agent which is more expensive than the calcium chloride snowmobilizing agent.

Alternatively, a liquid snow remover containing components such as industrial grade salt may be used as an anti-icing agent at a lower cost, while the performance of preventing freezing is lower than that of a calcium chloride snow remover, Likewise, it can be used as an anti-icing agent in a mixed system by spraying a friction agent such as sand along with a liquid snow remover.

According to this configuration, it is possible to prevent various side effects of using a snow remover containing calcium chloride by spraying on the road by optimally determining the spray amount of the anti-icing agent. In addition, by using the hot water heated instantaneously as a snow remover, it is possible to minimize the time required for producing salt water, which is a mixture of calcium chloride and water at a constant concentration in the conventional snow removal work, It offers the advantage of being able to perform quickly and smoothly.

According to another preferred embodiment of the present invention, the step of preventing the freezing of the hot water can be realized by applying the air of warm air to the outside at a predetermined heating temperature and air volume.

As described above, according to another preferred embodiment of the present invention, the snow removal method using high temperature water can perform snow removal work with hot water and hot wind without using any calcium chloride snow remover or auxiliary snow removal system, There is no possibility of causing a fundamental problem that may occur in the method of using the snow-removing agent and the snow-removing method using the environmentally-friendly snow-removing agent, and the snow removal operation can be performed quickly and smoothly.

According to another preferred embodiment of the present invention, the step of preventing the freezing of the hot water can be realized by operating the heating cable installed at a predetermined position on the road at a predetermined operating temperature. That is, considering the snow removal conditions such as outside snowfall amount, high temperature water spray amount, temperature and humidity at a predetermined position, and snow removal environment such as outside wind direction and wind speed, which are provided from the step of controlling the snow removal state, It is possible to determine the amount of heating to be applied to the road in order to remove the high temperature water and to prevent the freezing of the high temperature water by providing a heating system for operating the heating cable installed at a predetermined position at a predetermined operating temperature There is a number.

Accordingly, the present invention provides a heating system for preventing freezing of high-temperature water. According to another aspect of the present invention, there is provided a method of removing snow by hot water and hot air, , It is possible to carry out the snow removal process by using the hot water and the heating cable without using any calcium chloride snow remover or auxiliary snow remover, There is no fear that fundamental problems will occur, and snow removal can be performed quickly and smoothly

As described above, in the snow removal method using hot water according to the present invention, snow removal using high temperature water is performed instead of using prior art calcium chloride or any other snow removing agent, It is possible to solve the problem of environmental pollution caused by the work. In addition, according to the snow removal method using the hot water according to the present invention, it is possible to determine the injection amount of the hot water under the optimum condition by controlling the snow removal operation based on the external snow removal environment, It is very economical because there is no need to use various parts to control the concentration of calcium chloride in the snow removal method using snow remover.

In addition, according to various preferred embodiments of the present invention, the snow is removed by the hot water at the completion of the snow removal operation without using any calcium chloride snow remover containing calcium chloride or other ingredients, In order to prevent freezing of the hot water so as to prevent the generated water from freezing on the road at a low temperature in the winter, it is preferable that a predetermined amount of the anti-icing agent to be sprayed out based on the data received from the step of controlling the snow- It is possible to determine the concentration of the heating cable and the predetermined injection amount, determine the heating temperature and the air flow amount of the air to be externally applied, or determine the operating temperature of the heating cable installed at a predetermined position.

Therefore, it is possible to use an eco-friendly antiseptic agent as an anti-icing agent or a friction agent such as low-priced snow remover and sand such as industrial salt, or to use hot water and hot wind without using any calcium chloride snow remover, It is possible to perform the snow removal work only by the system or the heating system, so that it is possible to solve various problems occurring in the snow removal method and snow removal apparatus of the prior art.

Now, with reference to FIG. 2, a method of controlling the snow removal state based on the external snow removal environment in the snow removal method using the hot water of the present invention will be described in detail.

Referring to FIG. 2, a block diagram of a method of controlling the snow removal state based on an external snow removal environment by the controller 30 in the snow removal method using hot water according to the present invention is shown.

According to one embodiment of the present invention, the controller 30 may include a snowfall measuring means, such as, for example, an ultrasonic design 32, for measuring the snowfall amount in order to perform the step of controlling the snowfall state, A hygroscope 34 for measuring the temperature and humidity of the air, and a wind direction anemometer 36 for measuring the wind direction and wind speed of the outside. In addition, at least one CCTV 38 installed at an appropriate external position so as to receive the external snowing state as an image and a flow meter (not shown) for measuring the injection amount of the hot water sprayed to the outside to directly perform snow removal 40 are provided. All data related to the snow removal environment measured from the ultrasonic design 32, the hygroscope 34, the wind direction anemometer 36, the CCTV 38 and the flow meter 40 are received by the controller 30, Is compared with the data of the database previously stored in the controller 30.

The data stored in advance in the database of the controller 30 may be stored in various data such as the snowfall amount, the amount of injection of the hot water, the temperature at a predetermined position, and the like, in order to make the snow removal work performed in an actual road situation an optimum condition, Humidity, external wind direction and wind speed.

For example, since the optimum injection amount of the hot water at a predetermined position is already input to the database under the conditions of the temperature and humidity, and the wind direction and the wind speed for an expected snowfall amount, the actual snow removal work is performed The control of the injection amount of the hot water is performed in a microprocessor programmed to adjust the injected amount of the hot water corresponding to an external snow removal environment such as a snowfall amount changing instantaneously.

When the snow removal by the injection of the high temperature water is completed, a signal for stopping the injection of the high temperature water is sent from the microprocessor built in the controller 30 to stop the injection of the high temperature water and to prevent the freezing of the high temperature water Step is initiated.

Referring to FIG. 3, FIG. 3 schematically shows a system for performing a step of preventing freezing of hot water according to a preferred embodiment of a snow removing apparatus using hot water according to the present invention.

Likewise, the installation position and the interval of the respective injection nozzles 20 can be arbitrarily determined in consideration of the width of the road, the lane on which the snow removal operation is performed, the inclination of the road surface, etc., The injection nozzle 20 can be changed to a fixed nozzle or a rotary nozzle in any way in consideration of the spraying direction of the spray nozzle 20, which is well known in the technical field of the present invention.

Likewise, a structure for measuring the external snowfall amount, the injection amount of the hot water injected to the outside, the temperature and the humidity at the predetermined position, and the external wind direction and the wind speed to control the snow state performed by the hot water sprayed to the outside, A microprocessor for performing a comparison and a substantial control command with respect to the structure of the database related to the snow accumulation amount, the injection amount of the high temperature water, the temperature and humidity at the predetermined position, Are also well known in the prior art, so a detailed description thereof will be omitted.

3, when a signal for stopping the injection of the hot water is generated from the controller 30, the on-off valve 18 is closed and the movement of the hot water through the transfer conduit 16 is stopped, 20 is stopped and the operation for preventing the freezing of the hot water is started.

In order to prevent freezing of the hot water, the concentration and the injection amount of the anti-icing agent (for example, eco-friendly snow remover) stored in advance in the separate anti-icing agent tank 60 are determined by the microprocessor stored in the controller 30 .

When the outside temperature and humidity at a predetermined position measured during the spraying of the anti-icing agent through the injection nozzle 20 reaches the predetermined temperature and humidity of the database stored in the controller 30, the controller 30 A signal for stopping the spraying of the anti-icing agent is generated from the microprocessor stored inside the mixing tank 80. Accordingly, the discharge port of the mixing tank 80 is closed to stop the spraying of the anti-icing agent.
