Detailed Description
In order to make the purpose, technical solution and advantages of the present application more apparent, the present application is further described in detail below with reference to fig. 1 and 2 and the embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The embodiment of the application discloses new trend system of discharging fume.
Referring to fig. 1, the fresh air and smoke exhaust system is a system having an air supply state and a smoke exhaust state, and the air supply state and the smoke exhaust state can be switched with each other. The fresh air smoke exhaust system comprises a public pipeline 1, a fresh air pipeline 4, an exhaust pipeline 5, an air supply pipeline 2 and an air exhaust pipeline 3. One end of the public pipeline 1 is respectively communicated with one end of the air supply pipeline 2 and one end of the air suction pipeline 3, and the other ends of the air supply pipeline 2 and the air suction pipeline 3 are respectively communicated with the indoor environment. Because new trend system of discharging fume will carry out air supply work or the work of discharging fume to every room in the building, so the one end intercommunication of public conduit 1 has a plurality of supply air duct 2 and a plurality of exhaust duct 3, and all communicates in every room and is provided with the uncovered of at least one supply air duct 2 and the uncovered of at least one exhaust duct 3 to make the new trend can pour into indoorly, the foul smell can discharge indoorly. The air supply pipeline 2 and the air exhaust pipeline 3 in the same room can form a fresh air and smoke exhaust subsystem. The other end of the public pipeline 1 is fixedly connected with one end of a fresh air pipeline 4 and one end of an exhaust pipeline 5, and the other ends of the fresh air pipeline 4 and the exhaust pipeline 5 are respectively communicated with the atmospheric environment. Public pipeline 1, fresh air pipeline 4, exhaust duct 5, supply air duct 2 and exhaust duct 3 all can adopt high temperature resistant materials such as galvanized steel sheet to make, and two pipelines accessible welded mode intercommunication.
A first fan M1 is provided in the fresh air duct 4. The first fan M1 is used to make air enter the fresh air duct 4 from the opening of the fresh air duct 4. The exhaust duct 5 is provided with a second fan M2 therein. The second fan M2 is used to exhaust the smoke from the opening of the exhaust duct 5 when smoke exists in the room. The first fan M1 and the second fan M2 can be electric control fans, and the working power of the fans can be adjusted according to actual conditions.
Valves are arranged on the public pipeline 1, the fresh air pipeline 4, the exhaust pipeline 5, the air supply pipeline 2 and the air exhaust pipeline 3. The valve FM-2 on the fresh air pipeline 4 can be positioned at one end of the fresh air pipeline 4 connected with the public pipeline 1, the valve FM-3 on the exhaust pipeline 5 can be positioned at one end of the exhaust pipeline 5 connected with the public pipeline 1, the valve FM-5 on the air supply pipeline 2 can be positioned at one end of the air supply pipeline 2 connected with the public pipeline 1, and the valve on the air exhaust pipeline 3 can be positioned at one end of the air exhaust pipeline 3 connected with the public pipeline 1.
Considering that the outdoor environment will affect the first fan M1, a valve FM-1 may be further disposed at the open end of the fresh air duct 4.
The valves on the public pipeline 1, the fresh air pipeline 4, the exhaust pipeline 5, the air supply pipeline 2 and the air exhaust pipeline 3 can be electric control valves.
The valve FM-4 on the public pipeline 1 is positioned at one end of the public pipeline 1 connected with the fresh air pipeline 4 and the exhaust air pipeline 5. The valve FM-4 on the public pipeline 1 and the valve FM-6 on the air draft pipeline 3 can adopt an electric control fusing valve. When the fresh air smoke exhaust system is in a smoke exhaust state, smoke exists indoors. If the smoke is high-temperature smoke which possibly influences the fresh air smoke exhaust system, in order to protect the fresh air smoke exhaust system, when the smoke temperature reaches a specific high temperature, the valve FM-4 on the public pipeline 1 and the valve FM-6 on the air exhaust pipeline 3 are automatically closed so as to protect the fan and the circuit.
The smoke exhaust state of the fresh air smoke exhaust system mainly aims at the indoor fire hazard occurrence condition. When the fresh air smoke exhaust system is in a smoke exhaust state, the second fan M2 is in an open state and the first fan M1 is in a closed state, the valves on the exhaust duct 5, the common duct 1 and the exhaust duct 3 are in an open state and the valves on the fresh air duct 4 and the air supply duct 2 are in a closed state. In order to prevent air pressure difference between the indoor and the atmospheric environment after smoke discharge, an air supplement pipeline can be arranged to supplement air while smoke is discharged.
Referring to fig. 2, the fresh air smoke exhaust system further includes a controller. The controller can control the valves on the public pipeline 1, the fresh air pipeline 4, the exhaust pipeline 5, the air supply pipeline 2 and the air exhaust pipeline 3, particularly can control the valves to be opened or closed, and can also control the first fan M1 and the second fan M2 to be opened or closed.
The controller includes a manual control dial.
When a fire disaster occurs indoors, when people find the fire disaster, people can operate the manual control disc to control the first fan M1 to be opened and the second fan M2 to be closed, and control the valves on the public pipeline 1, the exhaust pipeline 5 and the exhaust pipeline 3 to be opened, and control the valves on the fresh air pipeline 4 and the air supply pipeline 2 to be closed, so that the fresh air smoke exhaust system is in a smoke exhaust state to start smoke exhaust work.
In order to reduce the indoor smoke concentration in case of an indoor fire, the fresh air smoke exhaust system can also automatically control the first fan M1 to be opened and the second fan M2 to be closed, control the valves on the public pipeline 1, the exhaust pipeline 5 and the exhaust pipeline 3 to be opened, and control the valves on the fresh air pipeline 4 and the air supply pipeline 2 to be closed, so that the fresh air smoke exhaust system is in a smoke exhaust state.
Therefore, the fresh air smoke exhaust system can also comprise a fire alarm device, a smoke sensing alarm device and a temperature sensing alarm device.
The fire alarm device can detect whether a fire disaster occurs indoors or not, and when the fire disaster occurs indoors, the fire alarm device outputs a high level signal, namely the fire alarm device outputs a fire alarm signal. When no fire occurs indoors, the fire alarm device outputs a low level signal, namely the fire alarm device does not output a fire alarm signal. The fire alarm device may be a fire alarm.
The smoke alarm device can detect indoor smoke concentration value, and when the indoor smoke concentration value is larger than the smoke concentration value preset in the smoke alarm device, the smoke alarm device outputs high-level signals, namely the smoke alarm device outputs smoke alarm signals. When the indoor smoke concentration value is smaller than the smoke concentration value preset in the smoke sensing alarm device, the smoke sensing alarm device outputs a low-level signal, namely the smoke sensing alarm device does not output a smoke sensing alarm signal. The smoke alarm device can be an ion smoke detector and the like.
The temperature sensing alarm device can detect an indoor temperature value, and when the indoor temperature value is greater than a preset temperature value in the temperature sensing alarm device, the temperature sensing alarm device outputs a high-level signal, namely the temperature sensing alarm device outputs a temperature sensing alarm signal. When the indoor temperature value is smaller than the temperature value preset in the temperature sensing alarm device, the temperature sensing alarm device outputs a low level signal, namely the temperature sensing alarm device does not output a temperature sensing alarm signal. The temperature sensing alarm device can be an electronic temperature sensing detector and the like.
The controller is connected with the fire alarm device, the smoke sensing alarm device and the temperature sensing alarm device and is used for receiving and processing the fire alarm signal, the smoke sensing alarm signal and the temperature sensing alarm signal. When the controller receives any one or more of a fire alarm signal, a smoke alarm signal and a temperature alarm signal, the controller outputs a first control signal. The first control signal is used for controlling the valves on the common pipeline 1, the exhaust pipeline 5 and the exhaust pipeline 3 and the second fan M2 to be in an open state, and the valves on the fresh air pipeline 4 and the air supply pipeline 2 and the first fan M1 to be in a closed state.
The valves on the public pipeline 1, the fresh air pipeline 4, the exhaust pipeline 5, the air supply pipeline 2 and the air exhaust pipeline 3, the first fan M1 and the second fan M2 are respectively connected with the output end of the controller and controlled by a first control signal. When a fire occurs, the controller receives any one or more signals of a fire alarm signal, a smoke alarm signal and a temperature alarm signal and outputs a first control signal, so that the valves on the public pipeline 1, the exhaust pipeline 5 and the exhaust pipeline 3 and the second fan M2 are opened, the valves on the fresh air pipeline 4 and the air supply pipeline 2 and the first fan M1 are closed, and the smoke exhaust system automatically switches to a smoke exhaust state to start smoke exhaust operation.
In order to save unnecessary resources used in the smoke exhaust process, the smoke exhaust can be performed by determining the number of the valves FM-6 on the ventilation pipe 3 according to the fire occurrence area. A smoke alarm device, a fire alarm device and a temperature alarm device can be arranged in each room, and the smoke alarm device, the fire alarm device and the temperature alarm device form an automatic smoke exhaust subsystem together with a fresh air smoke exhaust subsystem. When the controller receives a fire alarm signal, a smoke alarm signal or a temperature alarm signal in the automatic smoke exhaust subsystem, the controller outputs a second control signal. The second control signal is used for controlling the valve FM-5 on the corresponding air supply pipeline 2 in the automatic smoke exhaust subsystem to be closed, the valve FM-6 on the corresponding air exhaust pipeline 3 to be opened, controlling the second fan M2 and the valve FM-3 on the air exhaust pipeline 5 to be in an open state, and controlling the valve FM-1, the valve FM-2 and the first fan M1 on the new air pipeline 4 to be in a closed state.
When a fire occurs, a fire area can be determined by the positions of a smoke alarm device outputting a smoke alarm signal, a fire alarm device outputting a fire alarm signal, and a temperature alarm device outputting a temperature alarm signal. In the room with fire, the controller outputs a second control signal to control the opening of the valve FM-5 on the air draft pipeline 3 in the corresponding automatic smoke exhaust subsystem, so that the air draft pipeline 3 where the valve FM-5 is located starts to perform smoke exhaust work.
The air supply state of the fresh air smoke exhaust system can enable fresh air to flow indoors. When the fresh air and smoke exhaust system is in an air supply state, the first fan M1 is in an open state and the second fan M2 is in a closed state, the valves on the fresh air pipeline 4 and the air supply pipeline 2 are in an open state, and the valves on the exhaust pipeline 5, the public pipeline 1 and the air exhaust pipeline 3 are in a closed state.
No matter the new trend system of discharging fume is in air supply state or in the state of discharging fume, air and smog all circulate the pipeline in new trend system of discharging fume. Both air and smoke may contain impurities. In order to improve the adverse effect caused by the fact that two states of the fresh air and smoke exhaust system share one set of pipeline, filters can be arranged in the fresh air pipeline 4 and the exhaust pipeline 5.
The filter can filter out impurities contained in the air when the air flows through so as to obtain purer gas; it is possible to filter out impurities contained therein when smoke flows therethrough and to reduce pollution of the public pipe 1 by smoke. The filter in the fresh air duct 4 may be communicated between the valve FM-1 and the first fan M1 disposed near the opening of the fresh air duct 4, and the filter in the exhaust duct 5 may be disposed at the opening end of the exhaust duct 5.
A pressure difference alarm can be arranged at the position where the filter is arranged. The pressure difference alarm is used for detecting the gas pressure difference value on two sides of the filter. The differential pressure detector comprises two probes. One probe is located on one side of the filter and the other probe is located on the other side of the filter. When the pressure difference value generated by the gas pressure values collected by the two probes of the pressure difference alarm is larger than the preset pressure difference value in the pressure difference detector, the pressure difference alarm outputs a pressure difference alarm signal, so that the influence of impurities filtered by the filter on the gas flow in the pipeline can be reflected, and the filter needs to be replaced. Otherwise, the pressure difference detector does not output a pressure difference alarm signal.
The implementation principle of the embodiment is as follows: the fresh air smoke exhaust system has an air supply state and a smoke exhaust state. In the fresh air smoke exhaust system, two states share one set of pipeline work, and the switching between the two states can be realized by opening or closing valves on all pipelines and opening or closing two fans in the system. When a fire disaster occurs indoors, if people find the fire disaster, the people can operate the manual control panel to control the valves and the fans on all the pipelines so as to open the smoke exhaust state to exhaust smoke in the indoor smoke. If no person is in the room, the fire alarm device, the smoke alarm device and the temperature alarm device in the room can be detected. When the controller receives a fire detection signal, a smoke detection signal or a temperature detection signal, the valves and the fans on all the pipelines can be controlled to open the smoke exhaust state to exhaust smoke in the room. The fresh air pipeline 4 and the air suction pipeline 5 are provided with a filter and a pressure difference detector so as to improve the efficiency of air supply and smoke discharge, and the filter can be replaced at any time according to an alarm signal.
The foregoing is a preferred embodiment of the present application and is not intended to limit the scope of the application in any way, and any features disclosed in this specification (including the abstract and drawings) may be replaced by alternative features serving equivalent or similar purposes, unless expressly stated otherwise. That is, unless expressly stated otherwise, each feature is only an example of a generic series of equivalent or similar features.
