Description

Condensation water remover of air suction type fire detection device {DEW CONDENSATION WATER REMOVER FOR FIRE SENSOR}

The present invention relates to a condensation water remover for an air suction type fire detection device. More specifically, a condensation water remover for an air suction type fire detection device capable of removing condensation water generated inside a sampling pipe due to a difference in internal and external temperatures. It's about.

As is well known, a fire detection device is a device that detects a fire and signals danger by sounding an alarm, and can minimize damage to valuable property and human life by extinguishing the fire at an early stage.

Fire detection devices are used to monitor and monitor large-scale warehouses, storage warehouses for combustible and combustible materials, large-area buildings such as buildings or apartments, and small-area buildings such as single-family homes or townhouses. and are installed in places that are difficult to manage.

Fire detection devices include fire detectors with an interlocked structure that operate in conjunction with a centrally controlled disaster prevention system depending on the installation location or monitoring area, and fire detectors with a stand-alone structure that operate individually in buildings with small areas such as single-family homes or townhouses. It is classified as a fire detection device.

Depending on the detection method, fire detection devices are roughly divided into a heat detection method that detects heat, a smoke detection method that detects smoke, and a flame detection method that detects flames.

Here, the heat detection method or flame detection method is a passive detection method that individually installs a detection sensor for temperature detection or flame detection on the indoor ceiling or wall, and detects the heat or flame generated in the event of a fire when it reaches the detection sensor. As a result, it is difficult to quickly detect a fire because the time from the beginning of a fire occurrence to detection of the fire is long, and there is a disadvantage in that it is difficult to detect the fire uniformly depending on the installed location of the detection sensor and the location of the fire occurrence.

On the other hand, the smoke detection method detects the smoke that first occurs at the beginning of a fire, so the time from the beginning of a fire to detection is short, so the fire can be detected quickly, and it has the advantage of enabling detection as uniformly as possible regardless of the installation location. For this reason, it has been widely used recently.

In particular, among smoke detection methods, the air suction type detection device is a method of detecting fire by actively sucking air from various locations through a piping network composed of sampling pipes, and can quickly detect the occurrence of a fire over a large area. The detection area can be expanded simply by installing additional sampling pipes in the piping network, making it very efficient when seeking to further expand the existing detection area.

As a prior art related to such an air-suction type detection device, 'Air-suction type fire detector', registered in Republic of Korea Patent No. 10-2488342 (registration date January 10, 2023), which was previously filed and registered by the present applicant, is disclosed.

The above prior art is “an enclosure connected to an outdoor air inflow pipe installed indoors and having an opening/closing door; A gas detection sensor attached to the top of the enclosure to analyze gas components in the outside air supplied from the outside air inlet pipe; A connection pipe installed inside the enclosure and connecting the outside air inflow pipe and the gas detection sensor; A three-way valve installed on the connection pipe; A bypass pipe connected to the three-way valve; A vacuum pump installed inside the enclosure, connected to the bypass pipe, and sucking in and discharging dust and foreign substances accumulated in the outside air inflow pipe and connection pipe; A power supply unit installed on the opening/closing door of the enclosure to supply power to the vacuum pump, gas detection sensor, and three-way valve; A controller installed on the opening/closing door of the enclosure to control the operation of the vacuum pump, gas detection sensor, and three-way valve, and to determine whether there is a fire by receiving data in real time from the gas detection sensor; An air suction type fire detector including a water trap installed at the bottom of the enclosure and collecting moisture contained in the outside air between the connection pipe and the gas detection sensor through a moisture adsorption filter and then discharging it to the outside through the open bottom at the bottom. ” is the gist of the technology.

However, the above-described prior art discharges moisture generated inside the connection pipe through a water trap. The moisture discharged from the water trap not only flows to the walls and floor, causing mold to grow, but also causes workers to work on slippery floors due to moisture. There were problems such as falling over, which could lead to an accident.

In addition, the above-described prior art had problems such as forming a visual environmental hazard, causing water leaks in gaps in the bottom layer due to frequent discharge of moisture, and preventing whitening of cement in the bottom layer.

In particular, when the sampling pipe is connected from a low-temperature warehouse where food or cargo is stored at low temperatures to a room where the temperature is maintained above zero, condensation water generated inside the sampling pipe continues to flow due to the difference in internal and external temperatures, causing a large amount of moisture to form in the water trap. As this is released, mold increases and the floor becomes more slippery.

In addition, as a prior art for discharging moisture generated from a sampling pipe, Korea Patent No. 10-1845263 (registration date March 29, 2018) ‘Air suction type fire detection device’ is disclosed.

However, the prior art had a problem in that the water trap that discharges moisture was exposed to the outside and was easily damaged by a forklift transporting cargo, which could cause a malfunction of the fire detection device.

The purpose of the present invention is to remove condensation water generated inside the sampling pipe due to the difference in internal and external temperatures to prevent the occurrence of mold and worker accidents. The purpose is to provide a condensation water remover for an air-suction type fire detection device that can prevent fire detection.

In order to achieve the above object, the present invention includes a sampling pipe that intakes air, a housing that accommodates the exhaust end of the sampling pipe, and a fire installed on one side of the housing to detect fire through detection of air sucked into the sampling pipe. An air-intake type fire detection device including a detector, comprising a condensation water eliminator built into the housing to evaporate and remove condensation water generated inside and outside the sampling pipe that supplies air to the detector, the condensation water eliminator is a drain pipe connected to the sampling pipe accommodated inside the housing to drain condensation water, a sump tank with an exhaust hole formed to collect condensation water drained into the drain pipe and exhaust the evaporated gas, and evaporate the condensation water collected in the sump tank. The technical idea is to include an evaporation member.

The evaporation member is a guide duct that is connected to one side of the water collection tank and guides the wind direction to exhaust the gas in which the condensation water has evaporated through the exhaust hole, and is installed on the outside of the guide duct to evaporate the condensation water. It may include an evaporation fan that blows air.

The evaporation member may include a diaphragm installed at the bottom of the sump, and an ultrasonic vibrator that vibrates the diaphragm to dissipate condensation water in gaseous form.

The evaporation member may be comprised of a heater that increases the temperature to evaporate the condensation water collected in the sump.

According to the present invention, which is implemented as a solution described above, condensation occurring in the sampling pipe due to the difference in internal and external temperatures collects in the sump and evaporates to the evaporation member and does not flow to the wall and floor, thereby causing mold growth and slipperiness of the floor. It has a very useful effect in preventing accidents from occurring.

In addition, according to the present invention implemented as a solution described above, the installation cost of the water trap of the prior art can be reduced, and there is no water trap exposed to the outside of the housing, preventing malfunction of the fire detection device due to damage to the forklift. There is a very useful effect that can be prevented in advance.
