Description

Instrumentation Controls to Block the Effects of Corrosive Gases

The present invention is a technology for preventing harmful substances such as hydrogen sulfide inside the sewer from flowing into the instrumentation control device. Specifically, a line for protecting the power line that supplies power from the instrumentation control device to the equipment inside the sewer It relates to a technology that can prevent corrosion of internal equipment due to the inflow of harmful substances, particularly hydrogen sulfide, into the instrumentation control device through a protective tube, and can solve the problem of not being able to accurately measure harmful substances due to moisture.

A sewerage system is a type of underground discharge system that moves wastewater from households or industrial facilities to a wastewater treatment plant. In developed countries, sewers usually consist of pipelines connecting high-rise buildings and major underground wastewater storage facilities that carry wastewater to wastewater treatment plant facilities. A vertical pipe called a manhole connects the ground and major facilities, and it is also used as a means of checking or maintaining the sewage pipe and ventilating the gas generated from the sewer, and it makes it possible to straighten the angle of the pipe vertically and horizontally. Sewerage generally uses the principle of gravity and, if necessary, a pump is used.

A large number of manholes are connected to the pipe network leading to the sewage treatment plant. There are many devices in the manhole, such as an ultrasonic water level gauge that measures the water level, an Ottogi water level gauge, etc.

This is to prevent human damage due to gas poisoning due to corrosive gas in the pipe, solve the problem of measurement impossibility due to corrosion of the measurement sensor inside the pipe, sensor failure due to water level rise in the manhole, and the corrosive gas inside the control enclosure (panel). It is to solve various problems such as controller failure due to leakage.

Since these facilities are installed inside the sewer and it is difficult to directly operate them, an instrumentation control device equipped with a number of equipment for power supply and control to the facility is installed and operated on the ground nearby.

A schematic diagram of such a conventional instrumentation control device is shown in FIG. 1 . Referring to Figure 1, in the existing sewer interior (1) in which a manhole (2), etc. are installed, a water level gauge (4) and a gas containing hydrogen sulfide are collected in the sewage interior (1) to measure the concentration of hydrogen sulfide contained therein. Possible sensors 3 and pump 5 are installed and operated, and a power line 8 for supplying power to each facility from the instrumentation control device 100 in which a plurality of devices 6 described above is installed is installed and , a line protection pipe 7 for protecting the power supply line 8 is provided along the power supply line 8 .

In this case, as time passes, the corrosive gas leaked through the minute gap is diffused into the instrumentation control device 100 to cause corrosion of the metal contact point or the power line 8 .

In addition, in the case of the sensor 3, when moisture such as water vapor caused by the fluid inside the sewer 1 is present, the hydrogen sulfide around the sensor 3 is dissolved in the moisture. has occurred, and even in the high humidity time zone such as the morning, a dead zone where the concentration of hydrogen sulfide is not measured at all is sometimes formed.

According to this problem, there is a problem that precise measurement of the concentration of hydrogen sulfide inside is not performed, and as the sensor 3 is installed inside the sewer (1), the sensor itself corrodes or malfunctions, resulting in a measurement gap there is a problem.

Accordingly, the present invention is to provide a technology that can prevent harmful substances inside the sewer, particularly hydrogen sulfide, which causes corrosion of equipment inside the instrumentation control device, from flowing into the instrumentation control device through the above-mentioned line protection pipe, etc. There is a purpose.

In addition to the above-described technology, another object is to provide a technology capable of solving problems of dead zone formation and erroneous measurement when measuring existing hazardous substances in the sewage system.

In order to achieve the above objects, the instrumentation control device for blocking the inflow of corrosive gas according to an embodiment of the present invention is from an instrumentation control device mounted with a power supply device and a control device for supplying power to a facility installed near a sewage pipe. While accommodating a line protection tube accommodating a power line for supplying power to the equipment and a first connection region that is a connection region of the instrumentation control device, the gas flow between the internal equipments of the instrumentation control device and the first connection region is controlled. a bulkhead installed to block; and a discharging unit installed in a region in contact with an outer wall of the instrumentation control device as one region of the bulkhead and discharging the gas of the bulkhead to the outside.

The discharge unit may include: a penetrating portion penetrating the bulkhead and an outer wall of the instrumentation control device; and a fan installed in the penetrating portion to provide an external force for discharging gas to the outside.

It is possible to further include; a cleaning liquid spray unit installed outside the instrumentation control device near the discharge unit, and spraying the washing liquid toward the discharge unit to dissolve harmful substances present in the gas discharged through the discharge unit. .

It is possible to further include; a washing solution collecting unit installed under the washing solution spraying unit to collect the washing solution in which the harmful substances are dissolved.

In the partition wall part, a second connection area passing through the partition wall part is formed so that a power line connected from the first connection area and the power supply device to the line protection pipe goes to the first connection area inside the partition wall part, The first connection region and the second connection region may be sealed to block movement of the gas.

a hazardous gas storage unit for storing the gas transferred through a transfer line through which the gas in the sewer containing harmful substances is transferred from the sewage area from one side wall area of the sewer inside the partition wall; a sensor module for detecting a concentration of a hazardous substance in the hazardous gas storage unit; and a metering pump for applying a suction force so that the gas is transferred to the hazardous substance storage unit through the transfer line.

The hazardous material measuring unit may further include a moisture removal unit installed in the transfer line or the hazardous gas storage unit to remove moisture in the gas.

According to the present invention, the line protection pipe surrounds the first connection area connected to the instrumentation control device side, and the use of the instrumentation control device is reduced by the bulkhead portion that blocks the gas movement from other facilities of the instrumentation control device. Therefore, even if the sealing member of the first connection region is damaged, the harmful substances including hydrogen sulfide are introduced only to the partition wall portion, and at this time, the harmful substances are safely discharged to the outside by the discharge unit.

As a result, when harmful substances in the sewer, particularly hydrogen sulfide, which causes corrosion of equipment inside the instrumentation control equipment, are introduced into the instrumentation control system through the line protection pipe, contact with the corrosive equipment is minimized and the instrumentation control equipment There is an effect that the maintenance and maintainability are greatly improved.

In particular, since a hazardous substance measuring part capable of measuring the concentration of hazardous substances by collecting gas inside the sewerage and controlling moisture is installed in the partition wall, It is possible to remove the factors that hinder the accurate measurement of the concentration of hazardous substances, so it has the effect of enabling precise measurement of hazardous substances.

In the following description, the details described in the drawings are omitted, or excessively enlarged or reduced, in order to explain the function of each configuration of the present invention, but the illustrated matters are the technical features and scope of the present invention It will be understood that it is not intended to limit the

In addition, in the following description, a plurality of drawings will be simultaneously referenced and described in order to explain one technical feature or component constituting the invention.

Referring to the above drawings together, the instrumentation control device for blocking the inflow of corrosive gas according to an embodiment of the present invention (hereinafter referred to as 'the device of the present invention') includes a bulkhead part 10 and a discharge part 20 It is characterized in that it includes.

The bulkhead 10 is a facility installed near the sewer pipe, and the instrumentation control device 100 in which a power supply device and a control device for supplying power to the above-described sensor 3, water level gauge 4, and pump 5 are mounted. ), while accommodating the line protection tube 8 accommodating the power line 7 for supplying power to the equipment and the first connection area 11 which is the connection area of the instrumentation control apparatus 100, the instrumentation control device 100 For example, it means a closed box structure installed to block the gas flow of the first connection region 11 and internal facilities such as the bus bar 110 .

The bulkhead portion 10 is, for example, integrally formed to completely block the flow of gas or the like, or is implemented to be in welding or other sealing contact with the outer wall of the instrumentation control device 100, so that the gas is instrumented control It may be implemented so as not to flow into other facilities in the device 100 .

On the other hand, the wall surface of the partition wall portion 10 may be formed with a plurality of penetration portions in which the exhaust portion 20 to be described later, such as a fan through which the power line 7 passes or a fan for discharging gas, is installed while being sealed with a sealing member.

In this case, the power line 7 connected to the line protection pipe 8 from the power supply device 110 such as a busbar and the first connection area 11 described above is connected to the first connection area inside the partition wall 10 . This means that the second connection region 12 passing through the partition wall 10 is formed through the partition wall portion 10 in order to go to (11). Of course, as described above, the area in which the discharge part 20 is installed may also be formed to penetrate the outside. In this case, the outer wall of the corresponding area of the instrumentation control device 100 will be formed to penetrate.

Preferably, the first connection region 11 and the second connection region 12 are blocked by a sealing member, etc., so as to block the movement of a fluid such as gas, etc. Through this, the first connection region 11 or the line protection pipe 8 ), etc., to prevent gas containing harmful substances such as hydrogen sulfide from passing through the partition wall 10 .

The discharge unit 20 is a region of the bulkhead unit 10 and is installed in a region in contact with the outer wall of the instrumentation control device 100 { , and performs a function of discharging the gas of the bulkhead unit 10 to the outside.

The exhaust unit 20 may be provided with a filter for purifying gas, or the like, or may be passed through as it is and implemented so that the gas is naturally discharged. In addition, the discharge unit 20 includes a door 21 member that can be opened and closed for managing the configuration of a power line 7 that can be installed inside the partition wall 10 and a hazardous substance measuring unit 50 to be described later. Thus, the administrator can use the door 21 of the discharge unit 29 to check the inside of the bulkhead 10 or to manage equipment.

On the other hand, in various embodiments of the present invention, the following configurations may be included in order to more effectively discharge the gas.

First, the discharge unit 20 may include a fan installed there together with the partition wall unit 10 and a penetrating portion penetrating the outer wall of the instrumentation control device 100 to provide an external force for discharging gas to the outside. . Through this, by efficiently discharging the gas inside the partition wall 10 to the outside, as the amount of gas present inside the partition 10 increases, pressure is applied to the partition 10 so that the outer wall of the partition 10 is formed. It may be implemented to prevent damage or damage to the sealing member of the first connection region 11 or the second connection region 12 .

On the other hand, the gases discharged to the outside through the discharge unit 20, in particular, may contain a trace amount of hydrogen sulfide described above, thereby causing a bad odor or corrosion problem of the adjacent external installation structure.

In order to solve this problem, in another embodiment of the present invention, the device of the present invention may further include at least one of a washing solution spraying unit 60 and a washing solution collecting unit 61 as shown in FIG. 4 . .

The washing liquid spraying unit 60 is installed on the outside of the instrumentation control device 100 near the discharging unit 20 as shown in FIG. 4 , and spraying the washing solution toward the discharging unit 20 , the discharge unit It functions to dissolve harmful substances present in the gas discharged through (20).

At this time, preferably, the discharge unit 20 is composed of the above-described fan, so that the gas is discharged while applying an external force to the outside by the fan. Since the movement direction is set in an outward direction according to an external force, it is possible to effectively prevent the washing liquid from entering into the partition wall 10 .

On the other hand, harmful substances such as hydrogen sulfide are dissolved in the washing solution that comes into contact with the gas discharged while being sprayed through the washing solution spraying unit 60 . Natural drainage may adversely affect environmental pollution, so in the present invention, as shown in FIG. 4 , a drip tray structure such as a washing liquid collecting unit 61 is installed in the lower part of the washing liquid spraying unit 60, and it is harmful to the ground. It can be impermeable to the cleaning solution in which the substance has been dissolved.

In addition, a purification line 62 for, for example, a physical or chemical purification function may be installed in the cleaning liquid collecting unit 61 to purify the cleaning liquid in which harmful substances are dissolved and finally discharge it to the outside.

On the other hand, gas containing harmful substances such as hydrogen sulfide is present inside the partition wall 10, and accordingly, a configuration for measuring the concentration of harmful substances may be included in the sealed box-shaped member.

The hazardous substance measuring unit 50 may be installed in a box-shaped structure wrapped with a separate sealing member inside the partition 10 as shown in the drawings, for example. The hazardous substance measurement unit 50 includes a hazardous gas storage unit 51 , a sensor module 52 , and a metering pump 53 .

The hazardous gas storage unit 51 is a sealed box, and is installed inside the instrumentation control device 100 for controlling the equipment installed for opening and closing the pipe in the sewer 1 and transferring the sewage, and to perform the function of the present invention. It means a configuration in which the gas containing hydrogen sulfide transferred from the inside of the sewage system (1) is stored.

Hydrogen sulfide is produced a lot in places related to wastewater, such as sewage pipes, sewage pipes, sewage terminal treatment plants, wastewater treatment plants, sewage treatment plants, and landfills. However, the fatal among them can lead to fainting, respiratory arrest, and death from suffocation when exposed to more than 700 ppm in an enclosed place.

In addition, hydrogen sulfide is converted to SO2 by aerobic microorganisms. After being oxidized to SO3, when it is dissolved in water droplets (moisture) in the pipe part, sulfuric acid (H2SO4) is generated. It can corrode the components, which can cause problems.

To solve this problem, the hazardous gas storage unit 51 is installed in an area inside the instrumentation control device 100 that is sealed separately from the inside of the sewer system 1 so as to precisely check the concentration of hydrogen sulfide in the gas, It will be understood as a composition that performs the function of inhaling and storing hydrogen sulfide.

On the other hand, since the gas storage of the hazardous gas storage unit 51 is finite, in order to solve this problem, an exhaust fan structure (not shown) for periodically discharging the gas of the hazardous gas storage unit 51 to the outside is stored. It can be installed and driven to connect the part 51 and the outside. Of course, the operation of the exhaust fan structure may be controlled inside the instrumentation control device 100 or by a separate control unit.

In order to prevent corrosion and damage to various facilities as hydrogen sulfide or gas and moisture containing hydrogen sulfide are introduced into the instrumentation control device 100 under such an environment, in an embodiment of the present invention, a hazardous gas storage unit ( 51) is preferably formed to have a closed structure so that external moisture is not introduced or internal gas is not discharged. In particular, it is preferable that the region other than the above-described exhaust fan structure is formed to be sealed.

The sensor module 52 is configured to perform a function of checking (sensing) the concentration of hydrogen sulfide in the hazardous gas storage unit 51 . Of course, the sensor module 52 will be driven with power supplied by the power supply unit of the instrumentation control device 100 .

In the present invention, the sensor module 52 may be any device that measures the concentration of hydrogen sulfide in the gas, but is preferably configured as a sensor module having a specification that can block moisture.

The transfer line 30 extends from one side wall area 31 of the sewer interior 1 area under the manhole 2 to the hazardous gas storage unit 51, and the gas in the sewer interior 1 containing hydrogen sulfide is discharged from the sewage system. It means a pipe-type configuration to be transferred from the area to the toxic gas storage unit 51 . In addition, in order to prevent excess gas from being stored in the harmful gas storage unit 51 , a discharge line 40 for discharging the harmful gas back into the sewer may be installed adjacent to the transfer line 30 . The configuration of the discharge line 40 and the transfer line 30 may be understood as being composed of similar structures and materials.

In order to prevent an accident due to the inflow of moisture and hydrogen sulfide into the instrumentation control device 100 as mentioned above, the inflow of moisture is primarily prevented in the area of one side wall where the inside of the sewage system 1 and the transfer line 30 are connected. A filter and a sealing member for blocking may be additionally installed. In addition, the inflow of moisture may be additionally blocked by the configuration of the metering pump 53 and the moisture removal units 55 and 56, which will be described later.

The transfer line 30 is configured in a form in which a pipe such as a straight line or a curved line is connected, so that only the gas inside the sewer containing hydrogen sulfide (1) is transferred to the hazardous gas storage unit 51 without moisture entering. desirable.

The metering pump 53 refers to a pump for transferring a fluid that provides a suction force so that the gas is transferred to the toxic gas storage unit 51 through the transfer line 30 .

In the present invention, the metering pump 53 may be configured as a general peristaltic pump. As the volume of the fluid precisely and precisely defined in the metering pump 53 is sucked in the return stroke of the displacer and discharged to the injection pipe in the compression stroke, only the correct amount of gas can be introduced into the hazardous gas storage unit 51, , which is an essential configuration for precise measurement and prevention of ingress of moisture, which is the object of the present invention.

As the metering pump 53 , a solenoid, a motor, a dynamic pressure metering pump, etc. may all be used according to a pump drive. Precision Pump Drive refers to equipment that discharges a certain amount each time the pump is operated by applying the principle of intestinal peristaltic, which is the digestive action of animals. The liquid flows through a flexible tube inside the circular pump head, and as the rotor with several rollers rotates, the rollers and the circular pump head come into close contact. When the rotor rotates, the compression action takes place, so the liquid is transferred by pressure, and the liquid flows in such a way that one side is pushed along with compression by the next roller. This process is called peristalsis and is used in many biological systems, such as the gastrointestinal system. It was invented in 1932 when cardiologist Dr Michael DeBecky was a medical student. Such a peristaltic pump is variously called a metering pump, a tube pump, a roller pump, and the like.

The metering pump is mainly composed of three parts. Drive (drive body), the driving part that gives a constant speed to the rotor in the pump head, rollers and rotor parts that continuously discharge a certain amount using tubes of various sizes connected to the drive, from a very small amount to a large amount It is divided into a tubing part that selects and connects a tube according to various discharge capacities up to and various liquid materials.

In Drive (drive, main body), rpm directly affects the flow rate and the flow rate can be adjusted. Accurate and reproducible flow rate can be selected and the main body system can be controlled remotely. In addition, it has the advantage of being packaged to protect it from the surrounding environment against water and dust. The head is a part that directly affects the tube size and material, and the tube can be replaced. Many tubes can be used depending on the type of fluid to be transferred, and when using a chemical material, it is important to select the material of the head. Most of the standard type heads are characterized by accuracy and excellent reproducibility. If you look at the tubing part, various tubes can be used depending on the chemical application, and the lifespan of the tube varies depending on the liquid used and the duration of use. In particular, depending on the viscosity, temperature, and state of the liquid, the user can select various types of tubes to drive the product. In general, silicon tube is widely used. AND The metering pump flow rate is 0.1~3400mL/min for standard type and 10~45L/min for industrial type manufactured through custom production.

In the present invention, a gas-type metering pump is used so that a certain amount of gas is always introduced into the harmful gas storage unit 51, so that very precise, accurate, and real-time concentration sensing of hydrogen sulfide in the gas is possible.

On the other hand, even by the sealed structure of the metering pump 53 and the one side wall region 31 described above, moisture may be introduced into the hazardous gas storage unit 51 through the transfer line 30 . According to this, as described above, the hydrogen sulfide gas element is dissolved in moisture, which may cause a problem in which precise measurement is impossible.

In one embodiment of the present invention, as shown in FIG. 5 in order to completely solve this problem, the moisture removal units 55 and 56 may be included as an additional configuration of the device of the present invention.

As shown in FIG. 5 , the moisture removal units 55 and 56 are configured to remove moisture from the gas transferred to the toxic gas storage unit 51 through the transfer line 30 . In accordance with the above purpose, the moisture removal units 55 and 56 include at least one of the first heat exchanger 55 on the transfer line 30 side and the second heat exchanger 56 on the toxic gas storage unit 51 side. It can be understood as a configuration that

The first heat exchanger 55 and the second heat exchanger 56 are driven by the power supply of the instrumentation control device 100 described above, and the driving is controlled by a control unit or a control module of the instrumentation control device 100 to be described later. do.

The first heat exchanger 55 may be implemented as a heater attached to the transfer line 30 in order to heat the inside of the transfer line 30 in a direct or indirect heating method. Accordingly, the first heat exchanger 55 is operated so that the temperature in the transfer line 30 of the gas by the external temperature is higher than the dew point of the inner region including the gas, specifically, the hydrogen sulfide in the gas is transferred to the transfer line 30 . It is prevented from dissolving in the dew inside.

On the other hand, the second heat exchanger 56 may be implemented as a heater attached to the harmful gas storage unit 51 in order to heat the inside of the harmful gas storage unit 51 in a direct or indirect heating method. Accordingly, the second heat exchanger 56 is operated so that the temperature in the harmful gas storage unit 51 of the gas is higher than the dew point of the gas, specifically, the hydrogen sulfide in the gas is stored in the harmful gas storage unit 51 by the external temperature. It is prevented from dissolving in the dew inside.

On the other hand, the instrumentation control device 100 is, as described above, a configuration for controlling devices corresponding to a plurality of components included in the equipment such as sensors, pipes, and pumps in the sewage and the device of the present invention, or computing for corresponding control. It is a configuration in which the device, a power supply for supplying power to each component, and a communication module to be described later are installed. Accordingly, the instrumentation control device 100 is used for convenient access by the administrator and at the same time to prevent the inflow of gas or moisture in the sewer 1 as described above, the case of the instrumentation control device 100, etc. The configuration of the main body, as shown in the drawings, it will be preferably installed outside the sewage inner (1) area and moisture is blocked.

Meanwhile, in the present invention, a communication module may be further included to perform the functions of the present invention. The communication module is installed on the sensor board 54 or the like as shown in the drawings, or is installed in the instrumentation control device 100 to transmit the concentration value of hydrogen sulfide, which is a measured value received from the sensor module 52, to the outside. perform the function

On the other hand, in the present invention, the information on the moisture inside the hazardous gas storage unit 51 has a great influence on not only accurate and precise sensing of the concentration value of hydrogen sulfide but also damage to other equipment of the instrumentation control device 100 . Accordingly, the device of the present invention may further include the configuration of the humidity sensor (not shown) shown in the drawings.

As shown in the drawings, the humidity sensor (not shown) senses the humidity inside the hazardous gas storage unit 51 and transmits the sensed humidity data to the outside through the above-described communication module or the like.

Meanwhile. As the sensing value of the humidity sensor (not shown) is measured in real time, when it is used to remove moisture inside the hazardous gas storage unit 51, energy saving according to precise control of the driving of the moisture removal units 55 and 56 effects can be expected.

To this end, in the apparatus of the present invention, the control unit 80 as shown in FIG. 5 may be included in the control unit of the above-described instrumentation control device 100 or as a separate component thereof as an additional component.

The control unit 80 controls, for example, the driving of the metering pump 53 as well as the first heat exchanger 55 and the second heat exchanger 56 , the first heat exchanger 55 and the second heat exchanger. The operation of 56 may be controlled according to the sensing value of the above-described humidity sensor (not shown). For example, when the concentration of humidity sensed by the humidity sensor (not shown) exists or is sensed above the humidity corresponding to the dew point, the first heat exchanger 55 and the second heat exchanger 56 are driven and , when the humidity does not exist or is sensed to be less than the humidity corresponding to the dew point, feedback control for stopping the driving of the first heat exchanger 55 and the second heat exchanger 56 may be performed.

As described above, although the embodiments have been described with reference to the limited embodiments and drawings, those skilled in the art will understand that various modifications and variations are possible from the above description. Terms such as "include", "comprise" or "have" described above mean that a component without a particularly opposing description may be embedded, so other components are not excluded.
