Description

System for discharging gas in soil with dual case structure

The present invention relates to a soil gas discharge technology for discharging harmful soil gas such as radon existing in the soil layer under the floor of a building to the outside, and more particularly, to a soil gas discharge system having a double enclosure structure.

Sick buildings that cause pathological symptoms such as chronic cold, cough, phlegm, nasal irritation, respiratory distress, respiratory disease, headache, and eye irritation due to deterioration of indoor air quality caused by recent urbanization, building density, and complex housing types There is a growing social interest in the syndrome.

Sick house syndrome and soil gas from the soil layer are cited as the main causes of sick building syndrome. Sick house syndrome is carcinogenic substances such as benzene, toluene, chloroform, acetone, styrene, and formaldehyde, which are harmful substances from building materials and wallpaper used in new construction, and radon, asbestos, carbon monoxide, It is caused by pollutants such as carbon dioxide, nitrogen oxides, ozone, fine dust, and airborne bacteria.

Radon contained in soil gas and sick house syndrome causative substances is a naturally occurring colorless, odorless, tasteless, water-soluble radioactive gas, and has isotopes of atomic weights 219, 220 and 222, respectively, U-235, Th-232, As a radioactive decay product of U-222, it is a group 0 gas substance that is not chemically reactive, but when radon atoms in the air are inhaled through human respiration, some of them remain in the lungs and are separated into highly reactive metal atoms such as polonium, bismuth, and lead. do. In this process, harmful radiation is emitted to the sensitive lung tissue of the human body, causing lung cancer and the like.

Most of the radon, which is very harmful to health, comes from the soil or rocks of the building ground. Radon or other polluting gases that have passed through the soil layer and raised upwards continue to accumulate under the building floor. In general, the atmospheric pressure inside the building is lower than the pressure in the soil under the building. Due to the high pressure in the soil under the building, harmful gases such as radon are introduced into the room with a low pressure through the floor or wall of the building.

Radon introduced into the room does not easily escape to the outside and continues to accumulate indoors, becoming a risk factor that threatens the health of residents. In addition, since soil gas contains moisture in addition to radon gas, problems such as mold and bacterial growth occur due to the occurrence of condensation due to the temperature difference between indoor air or soil gas and outdoor air in summer and winter, and the soil exhaust gas system It may cause malfunctions in electrical systems such as fans.

In Korean Patent Publication No. 10-2019-0122605 (2019.10.30) invented and applied by the present inventors, a soil gas discharge system for discharging harmful soil gases such as radon existing in the soil layer under the building floor to the outside is proposed and have. This technology perforates the soil layer below the building floor and inserts a pipe, and through this, the soil gas containing radon in the soil layer is sucked and discharged to the outside, thereby preventing radon from penetrating into the building and harmful substances in the indoor air. It is designed to improve indoor air quality by discharging substances to the outside of the building.

In the Republic of Korea Patent Publication No. 10-2019-0122605 (2019.10.30), a soil gas discharge system of a rainwater prevention inlet type installed at a position higher than the roof of a building, and a single enclosure type installed at a position lower than the lower surface of the window frame of the building A soil gas discharge system is proposed. Since the soil gas discharge system of the rainwater prevention inlet type has to install the exhaust pipe vertically high, it is difficult to construct compared to the single enclosure type soil gas discharge system, and the appearance is not beautiful.

Therefore, the present inventors improve the housing structure of the single-enclosure type soil gas exhaust system presented as an embodiment in Korean Patent Laid-Open No. 10-2019-0122605 (2019.10.30) previously applied to improve soil gas discharge performance, prevent dew condensation A study was conducted on a soil gas discharge system with a new enclosure structure that can prevent inflow, reduce noise, and improve aesthetics.

At this time, since the slit grooves 250 are formed on both sides of the bottom surface of the enclosure body 210 , there is no risk of rain or snow flowing into the interior, and there is no risk of foreign substances such as fallen leaves or dust from entering the interior.

Figure 4 is a perspective view showing an embodiment of the inner box of the soil gas discharge system of the double enclosure structure according to the present invention. As shown in FIG. 4 , the inner box 151 according to this embodiment includes an inner box body 310 , a front panel 320 , and an exhaust pipe passage groove 330 .

The inner box body 310 has front and bottom surfaces respectively opened, and an intake fan receiving space 311 is formed therein. For example, the inner box body 310 may be implemented with a metal material or a flame-resistant plastic material that is strong from fire or external influences.

The front panel 320 integrally protrudes from the opened front surface of the inner box body 310 in both sides and the upper vertical direction, and is in close contact with the inner side of the rear surface of the enclosure body when the inner box 151 is accommodated in the enclosure body 210 .

The exhaust pipe passage groove 330 is formed in the central portion of the upper surface of the inner box body 310 and allows the exhaust pipe 130 to pass therethrough. In a state where the intake port of the intake fan 140 is coupled to the end of the intake pipe 120 passed through the intake pipe passage groove 240 formed in the center of the bottom surface of the enclosure body 210, the enclosure body 210 enters the enclosure body 310 ) is inserted from the front.

Then, since the front and bottom surfaces of the inner box body 310 are opened, respectively, the inner box body 310 is inserted into the enclosure body 210 without any interference, and the inner box body 310 is inserted into the rear surface of the enclosure body 210 . The front panel 320 formed on the front of the is in close contact.

At this time, when the size of the inner circumference of the back of the enclosure body 210 and the outside circumference of the front panel 320 are the same, the front panel 320 of the enclosure body 310 that is in close contact with the inside of the back of the enclosure body 210 is fitted. Since it is fixed in a custom manner, the inner box body 310 is fastened without flow inside the enclosure body 210 without a separate fastening means.

In this state, the exhaust pipe 130 is inserted through the exhaust passage 153, which is a spaced apart space between the inner box 151 and the outer box 152 of the double structure housing 150, and then the inner box body 310 is located in the center of the upper surface. After passing one end of the exhaust pipe 130 through the formed exhaust pipe passage groove 330 , one end of the exhaust pipe 130 is coupled to the outlet of the intake fan 140 . At this time, when using a T-shaped pipe as the exhaust pipe 130, the exhaust port in both directions is located in the exhaust passage 153, which is a spaced space between the inner box 151 and the outer box 152 of the double structure housing 150. will do

When the external temperature of the double-structured housing 150 is very low compared to the internal temperature, such as in winter, the exhaust passage 153, which is a spaced apart space between the inner box 151 and the outer box 152 of the double-structured housing 150, is used. The exhausted soil gas is condensed on the inner wall of the enclosure 152 and flows down along the inner wall of the enclosure 152 in the form of dew, and is discharged to the outside through the slit groove 250 .

However, when the difference between the external temperature and the internal temperature of the double-structured enclosure 150 is not very large, such as in summer, the inner box 151 and the outer box of the double-structured enclosure 150 in a gaseous state through the exhaust pipe 130 ( 152), the soil gas exhausted to the exhaust passage 153, which is a space between them, is not condensed and exists in a gaseous state, so there is a possibility that the soil gas flows back into the intake fan 140 side.

Since soil gas such as radon has high water solubility and strong adsorption power to water, the soil gas discharged through the exhaust pipe 130 is collected in the humidification spray sprayed by the humidifier 170 and discharged in the form of dew condensation. 151), since the installation space of the intake fan 140 is shielded, the condensation in which the soil gas is collected does not flow back into the installation space of the intake fan 140 inside the inner box 151.

On the other hand, according to an additional aspect of the invention, the insulation sound absorbing material 180 may be filled in the inner box 151 in which the intake fan 140 of the soil gas discharge system 100 of the double enclosure structure is installed. For example, the insulating sound absorbing material 180 may be a porous insulating sound absorbing material or a fiber insulating sound absorbing material, but is not limited thereto.

The insulating sound-absorbing material 180 filled in the inner box 151 in which the intake fan 140 is installed serves to prevent fire and reduces the noise of the intake fan 140 at the same time. By implementing in this way, the present invention has the advantage of being robust against fire and generating less noise. In this case, it may be implemented to mount a noise reducing device (not shown) for reducing noise instead of the insulating sound absorbing material 180 .

As shown in FIG. 5 , the moisture recovery unit 190 may be implemented in the form of a T-shaped pipe. An opening/closing part 191 that can be opened and closed in a direction not connected to the intake pipe 120 or the exhaust pipe 130 is formed, so that moisture can be discharged to the outside.

The direction in which moisture is collected in the moisture recovery unit 190 is preferably configured at an angle at which moisture can be automatically collected by gravity. The opening/closing part 191 that can be opened and closed of the moisture recovery part 190 is normally closed to prevent the intake fan 140 from consuming the suction power required for sucking and discharging the soil gas, and the moisture to the moisture recovery part 190 is prevented from being consumed. When a predetermined amount or more is recovered, the user may manually open the opening/closing unit 191 to discharge moisture.

On the other hand, by providing a sensor (not shown) for detecting the amount of moisture recovery, it detects that more than a certain amount of moisture is recovered in the moisture recovery part 190 and automatically opens the opening and closing part 191 to discharge moisture. may be
