Description

Airflow variable soil exhaust radon reduction control device {CONTROL APPARATUS FOR REDUCING RADON IN SOIL}

The present invention relates to an air volume variable soil exhaust radon reduction control device, and more particularly, to an air volume variable soil exhaust radon reduction control device capable of effectively reducing radon in soil entering a room by discharging radon in the soil out of a building. will be.

In general, radon (Rn) is a type of natural radioactive gas that causes alpha decay with a half-life of 3.8 days. It is introduced into the room through the air, but it is also generated from the uranium decay material contained in cement and earth and other interior and exterior materials used in building construction and flows into the room.

When radon enters the lungs through the respiratory tract, it kills cells in the lungs and becomes the main culprit in causing cancer. Therefore, the World Health Organization (WHO) and the US Environmental Protection Agency (USEPA) have determined that radon is second only to lung cancer after smoking. It is defined as a major causative substance that causes radon, and it is recommended to control the concentration of radon in the indoor air. Radon is also present in outdoor air and groundwater, but exposure through indoor air accounts for 95% of the exposure.

In other words, since radon is the heaviest gas on Earth, once it enters the room, it accumulates rather than escapes, and radon enters the lungs through human respiration and decays to emit alpha radiation. As an atomic nucleus (He2+), it has a weaker penetrating power than beta or gamma rays, but it has a relatively large mass and causes destruction of lung cells.

On the other hand, in order to reduce radon gas flowing into the room, periodic ventilation is mainly required by residents, but in the case of a cold winter or night, ventilation is not performed properly, so that residents are exposed to radon gas and suffer serious damage. .

In particular, in the case of classrooms where students live in groups, systematic management of radon gas is not carried out, so the health of students is concerned. In the current situation, facilities to reduce radon gas by measuring radon are obligatory to keep the radon gas of about 148 Bq/m3 or less.

As a prior art for managing indoor radon gas, Korean Patent Registration No. 10-1569270 (indoor radon removal device equipped with an air purifier) has been proposed. In this prior art, an air supply pipe that can supply fresh air is installed in the ceiling of a room such as a classroom, and an air exhaust pipe that sucks in and discharges polluted air is installed on the floor so that the air supplied through the air supply pipe passes through the air purifier. This is to bring fresh air into the room.

In addition, Korean Patent Registration No. 10-1650436 (Integrated control system for radon reduction facilities) describes a large classification in which a plurality of radon reduction facilities are classified into a plurality of categories, a medium classification in which each category of the large classification is classified into a plurality of places, and each of the intermediate classifications. A database is constructed by stratifying places into sub-classifications that have been classified into a plurality of radon influencing factors, and at least one radon influencing factor is sequentially identified in any one category at the level of the major classification, at least one place at the level of the middle classification, and at least one radon influencing factor at the level of the subclass By integrating and controlling a plurality of radon reduction facilities sequentially in each category unit, each place unit, and each radon influencing factor unit in a selection method, considering the characteristics of each place for radon exposure damage, there are numerous Systematic management and control of radon reduction facilities.

A typical radon gas reduction system installs a radon gas detection sensor to detect radon gas in each room or classroom, and then controls the ventilation facilities of each room or classroom according to the detected radon gas concentration to control each room or classroom. It is to manage the radon gas concentration of

On the other hand, in the case of domestic apartments or detached houses being built today, the sealing rate is very high at about 90%, so it is legally obligatory to install compulsory ventilation facilities.

This ventilation system is equipped with a static pressure ventilation fan so that it is minimally affected by the number of floors and the external environment, and is manufactured to focus only on indoor and outdoor air ventilation. Therefore, in the process of product installation, there are many cases where some products form indoor negative pressure due to internal pipe installation problems.

Because of this problem, it is often found in the generation where more radon is emitted indoors. The highest concentration of radon in the home is between 10:00 p.m. and 5:00 a.m. During this time period, the peak of domestic radon appears.

During these times, indoor ventilation should be continuously provided, but there is a problem of being exposed to radon as it is because ventilation is not actively performed due to heating and cooling problems.

Of course, there are total heat exchangers on the market that increase energy efficiency by exchanging the exhaust heat of the room through the exhaust fan to the supply air duct, but due to the nature of the ready-made product, the supply and exhaust amount of the total heat exchanger are specified, so there is a limit to precisely reducing radon .

On the other hand, in the case of schools, in the prior art, one fixed-speed soil exhaust fan is installed for each classroom, and when a plurality of multi-pipes are installed, the pressure operates differently depending on the length of each pipe. As a result, the suction pressure at a point far from the soil exhaust fan is low, so radon reduction cannot be effectively achieved.

This is the overall block diagram for

1 and 2, the air volume variable soil exhaust radon reduction control apparatus according to an embodiment of the present invention, a plurality of first to Nth soil exhaust piping parts (100-1 to 100-N) ( N is a natural number greater than 1), a guide pipe part 200, a plurality of first to N-th damper parts (300-1 to 300-N), a soil exhaust fan 400, a plurality of first to N-th radon The measuring units 500-1 to 500-N, a control unit 600, and a power supply unit 700 and the like are included.

It may include more. On the other hand, since the components shown in FIGS. 1 and 2 are not essential, the air volume variable soil exhaust radon reduction control apparatus according to an embodiment of the present invention may have more components or fewer components. .

Hereinafter, the components of the air volume variable soil exhaust radon reduction control apparatus according to an embodiment of the present invention will be described in detail as follows.

Each of the first to N-th soil exhaust piping parts 100-1 to 100-N is a plurality of first to N-th space parts 11-1 to 11-N separated by a predetermined area in the building 10 . They are buried in the floor, respectively, and perform a function of discharging radon emitted from the soil 1 existing under the bottom of each of the first to N-th spaces 11-1 to 11-N to the outside. At this time, the soil exhaust is a method in which high concentration radon emitted from the soil is sucked in from the middle before being introduced into the room and discharged to the outside of the building.

In the guide pipe 200 , each of the first to Nth soil exhaust pipe parts 100-1 to 100-N are connected to each other in communication with each other, and each of the first to Nth soil is connected to the roof side of the building 10 . It performs a function of inducing the flow of radon present in the exhaust piping (100-1 to 100-N).

Each of the first to Nth damper parts 300-1 to 300-N is installed one by one in each of the first to Nth soil exhaust piping parts 100-1 to 100-N, respectively, and each of the first to Nth damper parts 300-1 to 300-N. N performs a function of adjusting the flow rate of air moving the piping for soil exhaust (100-1 to 100-N).

Each of the first to N-th damper parts 300-1 to 300-N is installed to respectively control the air volume in the first to N-th soil exhaust piping parts 100-1 to 100-N, respectively, the control unit It is preferable that it is made of an automatic electric damper (Damper) capable of automatically adjusting the air volume according to the control of (600).

For example, each of the first to N-th damper parts (300-1 to 300-N) communicates with an unillustrated communication window formed in each of the first to N-th soil exhaust piping parts (100-1 to 100-N). It may be composed of a plurality of blades installed in a rotatable state on the window to open and close the communication window through rotation, and a driving motor or actuator that rotates the plurality of blades while being operated by the control unit 600 .

The soil exhaust fan 400 is installed in the guide pipe part 200, and is present in each of the first to Nth soil exhaust pipe parts 100-1 to 100-N according to the control of the controller 600. It functions to forcibly flow radon and exhaust it to the outside.

The soil exhaust fan 400 is a well-known one whose operation is controlled by the controller 600 and forcibly flows air by the rotation of the blade, and each of the first to Nth soil exhaust piping parts by the rotation of the blade. (100-1 to 100-N) and to allow the air in the inside of the guide pipe 200 to be forcibly discharged to the outside.

That is, it is preferable that the soil exhaust fan 400 is not a constant-speed exhaust fan, but a variable-air volume exhaust fan capable of varying the air volume according to the control of the controller 600 .

Each of the first to N-th radon measuring units 500-1 to 500-N is installed in each of the first to N-th spaces 11-1 to 11-N, respectively, and each of the first to N-th spaces (11-1 to 11-N) performs the function of measuring the concentration of radon.

Each of these first to N-th radon measuring units (500-1 to 500-N)) is preferably made of, for example, an ionization chamber type radon measuring sensor, but is not limited thereto, and for example, a device for detecting alpha particles. A surface barrier type, high purity semiconductor detector (pure Ge), a scintillation (scintillation) detector, a solid state junction counter, etc. may be applied.

That is, the radon measuring sensor of the pulsed ionization chamber type has a structure in which an electric field is formed by installing a probe-shaped electrode in the center of a metal cylindrical box and applying a bias voltage between the metal cylinder and the inner probe.

When alpha decay occurs inside the ionization chamber and alpha particles are released, the alpha particles are annihilated due to collision with air, but ionic charges are generated, so the alpha particles can be detected by absorbing them through the central probe and amplifying the signal. The sensor itself is composed of a metal cylinder and a probe, so it is very inexpensive, durable, and has the advantage of good ventilation because it is independent of light.

Looking at the surface barrier detector, a depletion layer such as a p-n junction is formed on the surface of a semiconductor due to a surface level or an oxide film, and thus, the vicinity of the surface becomes an obstacle for charge transfer. As a practical matter, gold is deposited on the surface of the n-type si by about 100 µm/cm 2 , and this is used as one electrode and radiation is incident on the back surface. Here, the thickness of the depletion layer is about 50 to 500 μm, and since the energy loss at the surface is small, it is mainly used for detection of charged particles generated by alpha radiation and has good energy resolution.

The high-purity semiconductor detector is generally referred to as a pure Ge detector. It is a high-purity Ge crystal with very little impurity concentration or defects, and it has very high electrical resistance at low temperatures and can apply a high bias voltage. The difference from Ge(Li) is that it can be stored at room temperature and only needs to be cooled with liquid nitrogen for measurement, so it is convenient to maintain and the energy resolution is not inferior to that of Ge(Li), so it is being put to practical use.

Looking at the scintillation detector, the phenomenon of emitting light when charged particles collide with a substance has been known for a long time, but luminescence by alpha radiation of zinc emulsion (ZnS) or NaI coating film is particularly strong, and detection and counting are possible with a magnifying glass in a dark room.

Such light emission is called scintillation (scintillation), and a material exhibiting this phenomenon is called a scintillator. In addition, a scintillation detector that combines a photomultiplier tube with a scintillator is called a scintillation detector.

On the other hand, the method of reading the output directly is mainly used for dosimetry and is called a scintillation dosimeter because it uses a scintillator. Any solid, liquid, or gas is used for the scintillator, and if liquid is used, it is a liquid scintillation counting device. say

The solid junction counter is a solid reverse bias p-n junction semiconductor, and is a counter designed to collect ionic charges from alpha particles passing through a depletion layer, and can be manufactured in a compact, mobile type.

A first control mode for controlling the opening at a set reference opening rate (O) and simultaneously controlling the soil exhaust fan 400 to operate for a preset operating time (eg, about 1 hour or more) at a preset reference operating rate (P) functions to perform

In this case, the reference open rate O is preferably set to any one of the open rates in the range of, for example, about 45% to about 55% (more preferably, about 50%). The reference operation rate P is, for example, preferably set to any one of operation rates in the range of about 45% to about 55% (more preferably, about 50%).

In addition, after performing the first control mode, the control unit 600 returns the radon concentration value measured by the first radon measurement unit 500-1 for a preset reference radon concentration reduction time (eg, about 1 hour or more). When the radon concentration is not reduced by the preset average reduction rate, the second control mode is performed in which the first damper unit 300-1 is further opened by the preset increasing opening rate from the current opening rate, and the first damper unit ( 300-1) performs a function of repeatedly performing the second control mode until the current open rate reaches the maximum open rate (eg, an open rate of about 100%).

In this case, the increased open rate is preferably set to any one of the open rates in the range of, for example, about 5% to 15% (more preferably, about 10%). The average radon concentration reduction rate is, for example, preferably set to any one of the average radon concentration reduction rates in the range of about 25% to 35% per hour (more preferably, about 30% per hour).

In addition, in the state of the maximum open rate of the first damper unit 300-1, the control unit 600 determines that the radon concentration value measured by the first radon measurement unit 500-1 during the reference radon concentration reduction time is the radon concentration.

In this case, the increased operation rate is preferably set to any one of the operation rates in the range of, for example, about 5% to 15% (more preferably, about 10%).

In addition, in a state where the maximum opening rate of the first damper unit 300-1 and the maximum operation rate of the soil exhaust fan 400 are reached, the control unit 600 controls the first radon measurement unit 500- during the reference radon concentration reduction time. When the radon concentration value measured from 1) is not reduced by the average radon concentration reduction rate, a preset inspection guide message for guiding the operation status check of the first damper unit 300-1 and the soil exhaust fan 400 is transmitted to the communication network.

In this case, although not shown in the drawings, the mobile communication network may include, for example, a Radio Network Controller (RNC). Meanwhile, although the WCDMA network is taken as an example, it may be a next-generation communication network such as a cellular-based 3G network, an LTE network, a 4G network, a 5G network, or other IP-based IP networks.
