Description

Rechargeable smoke exhaust system for fire fighting

The present invention relates to a flue gas system, in particular, power is supplied through a storage battery even in the event of a power outage or a power outage due to a fire to operate in real time, such as buildings, offices, small indoor spaces such as dormitory, one-room, high court, motel, container house, It is related to a capacitive exhaust system for fire fighting that can be applied to residential buildings, public buildings, warehouses, walls of buildings, windows, porches, and staircases.

When a fire occurs in a building, not only harmful gases, combustibles, and various toxic gases are generated, but also the oxygen concentration in the indoor air decreases due to the consumption of oxygen during combustion, and the oxygen concentration in the indoor air decreases due to the consumption of oxygen during combustion. Residents, such as high gas concentrations, suffer from gas poisoning or paralysis and, if severe, are threatened with life.

Therefore, in a high-rise building, it is necessary to have a smoke control system that blocks and discharges smoke in certain compartments so that smoke and toxic gases associated with the occurrence of a fire do not become an obstacle to evacuation.

In general, the term 'smoke control system' refers to a system that effectively discharges smoke and toxic gases generated during a fire to remove smoke that interferes with fire fighting activities. The system diagram of the existing ventilation system is installed in a high-rise building with 10 or more floors, so that in the event of a fire, a ventilation system is installed to prevent smoke or toxic gases from spreading to evacuation areas such as emergency passages and stairs to protect human life.

At this time, the configuration of such a ventilation system is a flue gas blower that sucks in smoke including toxic gases generated inside the building when a fire occurs, a supply air blower that supplies fresh air from outside, and a passage through which smoke is moved by the suction force by the flue gas blower. Flue gas duct, flue gas duct, which is a passage through which fresh air flowing in by the air blower flows, flue gas dampers controlled to seal a plurality of blades so that smoke generated by the fire moves along the flue gas duct, along the air duct In addition to the air supply damper that is controlled to open a plurality of blades to allow fresh air to flow in, it consists of a fire detector, a fire damper, a fire door, and a smoke control curtain.

In particular, the flue gas damper is connected to the flue gas duct, which is an air passage for discharging smoke, and it is important to prevent or prevent the initial suppression of fire, expansion of combustion, and human damage by discharging smoke generated during the fire to the outside through the flue gas blower. Plays a role.

In the event of a fire, the blades (wings) of the flue gas damper in the fire zone must be opened to discharge the smoke to the outside by the flue fan, and for this purpose, only the flue gas damper in the fire zone must be open. In other words, the blades of the flue gas dampers installed in the non-fire zones must remain fully closed. That is, in the non-fire zone, the flue gas damper blade must be completely closed so that the flue gas blower can suck smoke and harmful gases in the fire zone and smoothly discharge it to the outside of a high-rise building.

As shown in Fig. 2, the flue gas damper used for the above-described use has a horizontal arrangement of blades. More specifically, the flue gas damper is concavely formed so that both ends of the plurality of blades are engaged with each other (hinged), and thus, when the central damper shaft is rotated by a connecting link formed with a connecting hinge, it is connected to the remaining blades. It is a structure in which the rotation support shaft rotates along the connection hinge. That is, when the central damper shaft is rotated, the left and right remaining hinges are connected in series by the connecting hinge connected to the central damper shaft in the connection link object, such as a domino phenomenon, to open and close the blade of the exhaust damper. It is configured to adjust.

However, the flue gas damper operating in this principle, the damper shaft in the center of the flue gas damper is installed in the flue gas damper opening and closing device to install a plurality of blades in an airtight closed state and install the flue gas in the flue duct, and when the initial power is supplied, the flue gas damper It is rotated by the smoke damper opening and closing device mounted on. At this time, due to the characteristics of the flue gas damper structure as the blade is opened and closed, and the defects in the blade leakage gap generated during use, the closed state between the blades cannot be accurately performed, and thus there is a problem in that the ventilation system in a high-rise building cannot operate properly.

In addition, as the distance between the damper shaft in the center of the flue gas damper and the rotational support shaft increases, it is difficult to control a plurality of blades connected to the rotational support shaft only by the movement of the central damper shaft, and thus the mechanical play of the flue gas damper itself There is a problem in that it has a slit gap of 3 ~ 5% as a result.

However, the conventional flue gas damper has a problem in that exhaust efficiency is poor because the suction concentration is significantly lowered by horizontally inhaling during operation to exhaust smoke or harmful gases.

In addition, the conventional flue gas damper has a problem in that it is limited to the occurrence of a fire and performs a function of exhausting smoke and toxic gases, which cannot be utilized in everyday life.

It would be desirable to install it close to.

In addition, the oxygen sensor 30 checks the change in the amount of oxygen in the indoor space where the flue gas 50 is installed, and in the event of a non-fire, the fire extinguisher 50 does not generate a fire interlock signal with the fire hydrant 10 for ventilation. It is configured to transmit a signal that activates.

In addition, when the oxygen sensor 30 detects a signal from the local sensor unit 20 when a fire occurs in an indoor space where the flue gas 50 is installed, the oxygen amount sensor 30 controls the operation of the flue gas 50 and controls the exhaust air volume by changing the oxygen amount. Make up.

On the other hand, the fire hydrant 10 is connected to the local sensor unit 20 and the oxygen amount sensor 30 signally, and the power supplied to the building is charged to the storage battery 40.

It is constructed to be able to accurately and easily grasp the address, floor number, and room of the building.

The operation and effects of the present invention configured as described above are as follows.

As illustrated in FIGS. 1 to 12, the smokers 50 of the capacitive exhaust system 100 can be installed in various forms, which are largely installed using windows and windows or exterior walls of buildings. For example, it can be described, the smoker 50 is installed to face the inlet 58 toward the indoor side and the opening and closing flip 52 toward the outdoor side.

When the exhaust smoker 50 is installed on a window, a part of the upper glass of the window is partially removed and then fixedly installed by inserting the case 53, or the window of the window is opened to an area where the case 53 can be inserted, and then the window frame After the case 53 is fixed and installed, the opened / closed space of the window is blocked using a cabinet or a closing mechanism.

In addition, when the exhaust smoker 50 is installed on the outer wall of the building, an installation hole having a size to be inserted into the case 53 is formed on the outer wall, and then the case 53 is installed and fixed.

At this time, after installing the storage battery 40 in the case 53 of the flue gas 50 and signally connecting to the fire hydrant 10, the constant power is connected to the power supply means supplied to the building or from the fire hydrant 10. Connect to supply.

Thereafter, the local sensor unit 20 and the oxygen sensor 30 combined with the smoke detection sensor 11, the heat detection sensor 12, and the odor sensor 23 in the building space, especially the ceiling, are equipped with a fire hydrant 10 and a storage battery ( 40) Electrically connected to the control unit (41) installed in the unit, the storage battery (40) is supplied with power between the local sensor unit (20), the oxygen sensor (30), the fire hydrant (10), and the flue gas emergency bell (59) And a control unit 41 for blocking control and operation control.

Then, after the communication module 60 is installed on one side of the case 53 of the flue gas 50, it is set to interwork with a manager, a firefighting center, and a management program through the control unit 41 of each storage battery 40. The installation of the power storage type exhaust system 100 is completed by giving a unique identification number.

At this time, the flue gas 50 maintains a state in which the opening and closing flip 52 is closed and no electricity is supplied to the motor 57.

If the fire is generated after installing the capacitive exhaust system 100 and the operation according to the fire detection process is described as follows, the operating conditions are in common. Through 60), the non-fire operation status and the fire operation status are transmitted through real-time communication.

1. In non-fire situations, the operation of the capacitive smoke-reducing system 100 receives electricity from the fire hydrant 10 or the power supply to accumulate electricity, stops charging when fully charged, and recharges when the charge rate decreases. When receiving a signal detected by the oxygen amount sensor 30, when the amount of oxygen is insufficient than the value set in the indoor air, the opening and closing flip 52 is opened and the motor 57 is operated to rotate the fan 54 to rotate the room. It performs the purifying function of circulating indoor air by exhausting the polluted air to the outside.

The operation of the capacitive exhaust system 100 is operated so that the fire signal detected by the fire hydrant 10 is transmitted to the control unit 41 to operate the flue gas 50 and the flue gas emergency bell 59, and a local sensor unit. (20) When a fire is detected, it is transmitted to the control unit 41 to operate the flue gas 50 and simultaneously to the fire hydrant 10 to operate the emergency bell installed in the fire hydrant 10 to be notified.

In addition, when a power failure occurs due to the loss of a building electrical device due to a fire, the control unit 41 detects an interruption of the electricity supply.

2. In a fire situation, the smoker 50 installed at the fire site receives the signal through the fire hydrant 10 to open and close the opening and closing flip 52, and at the same time operate the motor 57 to rotate the fan 54 to rotate. The smoke and toxic gases generated by it are quickly exhausted outside the building.

3. One of the smoke detection sensor 11 and the heat detection sensor 12, the odor sensor 23 of the local sensor unit 20 due to a fire, or the oxygen amount due to a fire in the oxygen amount sensor 30 suddenly falls below a set value. When a decrease is detected, a signal is transmitted to the control unit 41 of the storage battery 40 to open and close the opening and closing flip 52, and at the same time, the motor 57 is operated to rotate the fan 54 at a set maximum rotational speed to fire. The smoke and toxic gases generated by it are quickly exhausted outside the building.

At this time, the smoke or toxic gas from the fire has a high pressure at the inlet side through the trumpet-shaped intake port 58, but the flow rate is slow, but the pressure decreases due to the smaller diameter as it progresses toward the 54 54, but the flow rate increases. The exhaust power is increased together with the suction power of 휀 54 to quickly exhaust smoke or toxic gases.

In addition, if the fire signal through the fire hydrant 10 or the fire signal through the local sensor unit 20 is no longer transmitted after the fire is extinguished or extinguished, the notification through the fire hydrant 10 stops and 휀 54 and The operation of the flue gas emergency bell 59 is stopped.
