Technical Field
The invention relates to a fire-proof building, in particular to a new air purification, induced air and smoke exhaust integrated fire-proof building.
Background
Current building that has new trend purifier, like Chinese utility model patent ZL201921345877.9, the name is the structure that building intelligence new trend purifier disclosed, and it includes the equipment main part, the surface of equipment main part is run through the embedding and is had indoor air-supply line, the inner wall fixedly connected with bracing piece of indoor air-supply line, the surface of bracing piece is equipped with the rotating tube, the middle part fixedly connected with bearing on bracing piece surface, the surface of bearing and the inner wall fixed connection of rotating tube. Although this fresh air purification device of building can be with indoor dirty air exhaust outdoor to outdoor fresh air inputs indoor again, lets indoor fresh air, nevertheless when indoor conflagration breaks out, can't discharge indoor high temperature flue gas outside the building fast, thereby does not possess the fire prevention and the function of stretching. In addition, in the existing building with the fresh air purification device, the air inlet pipe for inputting fresh air is usually made of plastic pipes, and the air inlet pipes of the households are communicated with each other, so that on one hand, the air inlet pipe can store dirt and dirty, is difficult to disinfect and cannot be cleaned after being used for a long time, and causes harm to human health, and on the other hand, once a certain room is in a fire, the air inlet pipe can be ignited, so that the households are all in great risk of being ignited.
The utility model discloses a patent ZL201720685728.1, the name is a fire prevention building discloses a fire prevention building structure, and it includes the floor of constituteing by floor bottom plate and floor curb plate and the escape way of each floor of intercommunication, be equipped with the emergency exit that is used for sealing the escape way on the escape way, escape way and exhaust pipe have transversely been seted up along horizontal on the floor bottom plate, escape way is located the pipe top of discharging fume, set up the manhole of intercommunication floor bottom plate up end and escape way and intercommunication floor bottom plate terminal surface and the exhaust hole of discharging fume the pipe under the floor bottom plate along vertical direction on the floor bottom plate, be equipped with the operating mechanism who is used for opening and close the manhole on the manhole, set up the perpendicular groove that is used for communicateing all escape ways in the floor curb plate, floor curb plate one side is equipped with the exhaust passage along vertical direction, all exhaust pipes of exhaust passage intercommunication. The building with the structure can reduce the speed of smoke spreading to high floors, slow down the spread of fire and improve the survival rate of escaping from the fire, but when the fire does not happen indoors, outdoor fresh air cannot be input indoors, so that the building does not have the function of fresh air purification.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide the integrated fire prevention building with the functions of fresh air purification, air induction and smoke exhaust, which not only can effectively prevent a room with a fire disaster in the building from spreading to the periphery, but also can input outdoor fresh air into the room when no fire disaster occurs in the building and has a simple structure.
In order to solve the technical problem, the building with integrated functions of fresh air purification, air induction and smoke exhaust comprises at least one vertical smoke exhaust channel arranged in the building, at least one smoke exhaust window is arranged in each independent room of each floor of the building, each smoke exhaust window comprises a smoke exhaust window and a smoke exhaust window door for sealing the smoke exhaust window, the smoke exhaust windows are in fluid communication with the vertical smoke exhaust channels, the vertical smoke exhaust channels extend out of the top surface of the building, positive and negative rotating fans are arranged in top sections of the vertical smoke exhaust channels, the smoke exhaust windows are horizontally arranged, the smoke exhaust window doors are vertically arranged, the tops of the smoke exhaust window doors are hinged with the smoke exhaust windows through hinges, fusible stoppers are arranged on the bottom surfaces of the smoke exhaust windows, and the inner side surfaces of the bottoms of the smoke exhaust window doors abut against the fusible stoppers.
As a preferred embodiment of the present invention, the vertical smoke exhaust channel is made of a metal plate, a bottom plate is disposed at the bottom of the vertical smoke exhaust channel, and an opening for cleaning the vertical smoke exhaust channel and a hole cover for closing the opening are disposed on the bottom plate; and a rain shade is arranged at the top of the vertical smoke exhaust channel.
As a preferred embodiment of the invention, a heat insulating gasket is provided between the smoke evacuation window and the vertical smoke evacuation channel, the smoke evacuation window being in fluid communication with the vertical smoke evacuation channel via the heat insulating gasket.
In a preferred embodiment of the present invention, the smoke evacuation door, the hinge, and the fusible stop are made of a hot melt material.
As a preferred embodiment of the present invention, a detection sensor is disposed in the smoke exhaust window, the detection sensor includes a smoke detection sensor or a temperature detection sensor, and the detection sensor is connected to the forward/reverse rotation fan.
After adopting the structure, the invention has the following beneficial effects:
the smoke exhausting window is horizontally arranged, the smoke exhausting window door is vertically arranged, the top of the smoke exhausting window door is hinged with the smoke exhausting window through a hinge, the bottom surface of the smoke exhausting window is provided with a fusible stop block, and the inner side surface of the bottom of the smoke exhausting window door is abutted against the fusible stop block, so that when a fire disaster does not happen indoors, the forward and reverse rotating fan is started to rotate forward, the forward and reverse rotating fan blows fresh air outside the roof downwards and inputs the fresh air into the indoor through the vertical smoke exhausting channel, and the indoor has fresh air; when a fire disaster happens to a certain room, the positive and negative rotating fans are started to rotate reversely, high-temperature smoke in the room on fire is guided upwards and quickly discharged out of the building through the vertical smoke exhaust channel, so that the indoor fire can not spread to adjacent rooms around, the fire disaster is controlled in the room, and the occurrence of larger fire disasters is effectively prevented.
The vertical smoke exhaust channel is preferably made of a metal plate, the bottom of the vertical smoke exhaust channel is provided with a bottom plate, the bottom plate is provided with an opening for cleaning the vertical smoke exhaust channel, and a hole cover for closing the opening.
