Description
Technical Field
The invention relates to a fire-fighting system, in particular to an electric explosion type double-phase flow bus cabin water spraying fire-extinguishing system.
Background
The bus is difficult to evacuate quickly when a fire occurs, and great threats are caused to the life safety and property of passengers. Bus fires have become one of the most deadly disasters for buses. Meanwhile, casualties caused by burning of various vehicles after accidents are frequent, the condition causes high importance from top to bottom in China, direct economic loss of the vehicles after burning can reach millions or even tens of millions, and the social adverse effects caused by the direct economic loss are immeasurable. And the passenger often all can have the passenger to take a bus when the bus passenger cabin catches fire, therefore water becomes the first choice as traditional fire extinguishing agent, and the current mode of putting out a fire of bus has not adapted modernization development requirement, therefore develops the better bus fire extinguishing systems of fire extinguishing effect and is the technological problem that awaits the solution urgently.
Disclosure of Invention
The invention aims to solve the problems and provides an electric explosion type double-phase flow bus cabin water spraying fire extinguishing system which can effectively extinguish fire in a bus and has high automation degree.
The technical scheme is as follows:
an electric explosion type double-phase flow bus cabin water spray fire extinguishing system comprises a water storage tank body, a starting controller, a plurality of temperature-sensitive alarms, a plurality of smoke-sensitive alarms, a water spray pipeline, gas-producing agent columns, a plurality of compensation gas-producing agent columns and a plurality of spray heads, wherein the water storage tank body is fixedly arranged in a storage cabin at the lower end of a bus; the water spraying pipeline is arranged in an interlayer of the inner wall of the passenger car, the upper end of the water spraying pipeline is fixedly arranged in the ceiling of the bus, the plurality of spray heads are respectively arranged on the water spraying pipeline according to set positions, and the pressure sensor is arranged in the water storage tank and connected with the starting controller through a wire; the gas generating agent explosive columns and the plurality of compensation gas generating agent explosive columns are respectively arranged in the detonation starter cylinder, the gas generating agent explosive columns and the plurality of compensation gas generating agent explosive columns are respectively provided with an electric blasting head, and the electric blasting heads are respectively connected with the detonation starter cylinder through conducting wires; the starting controller install in the driver's cabin panel board, starting controller passes through the wire and is connected with on-vehicle battery, starting switch installs on the driver's cabin panel board, starting switch passes through the wire with starting controller and is connected, a plurality of temperature sensing alarms and a plurality of smoke sensing alarms are installed respectively in the bus shed roof, a plurality of temperature sensing alarms and a plurality of smoke sensing alarms are connected with starting controller through the wire respectively.
And a thin film is fixedly arranged at the lower port of the water spraying pipeline.
The plurality of detonation initiator cylinders are two detonation initiator cylinders, the plurality of compensation gas production agent explosive columns are 4 compensation gas production agent explosive columns, and the gas production agent explosive columns and the 4 compensation gas production agent explosive columns are respectively arranged in the two detonation initiator cylinders.
The plurality of spray heads are double-phase flow colliding spray heads.
In the invention, when a bus runs, a temperature-sensitive alarm detects that the temperature in the bus rises to a set value rapidly, a smoke-sensitive alarm detects that the smoke concentration in the bus reaches the set value, a controller is started to output an electric signal to detonate a starter cylinder to detonate a gas generating agent column through an electric detonating head, and generated gas penetrates through an aluminum foil sealing layer to increase the pressure in a water storage tank body to 0.8 MPa, water in the water storage tank body breaks a film, and a double-phase flow spray head sprays water mist through a water spraying pipeline to quickly extinguish fire. In the spraying process, the pressure sensor in the water storage tank body 1 transmits the pressure in the water storage tank body to the starting controller in real time, when the pressure in the water storage tank body is less than 0.6 MPa, the starting controller outputs an electric signal to detonate the starter cylinder to detonate the compensation gas production agent explosive column through the electric detonation head, the pressure in the water storage tank body is increased, so that the water mist spraying is continued, the water mist strength is kept, and the fire extinguishing effect is improved.
The starting device adopts multiple detonating, and can detonate multiple gas-generating agent powder columns for multiple times according to the pressure in the water storage tank, so that the pressure in the water storage tank reaches the optimal value of water mist spraying. The calculation and the experiment prove that the water mist fire extinguishing effect is optimal when the pressure in the water storage tank is 0.6-0.8 MPa, so the pressure compensation is very important. The solid medicine blocks are detonated at the initial stage of starting, so that the pressure in the water storage tank body reaches 0.8 MPa to burst the film, and water mist is sprayed to start fire extinguishing. The plurality of offset gas generant grains detonate in succession and produce gas. However, as the amount of water in the water storage tank decreases, the gas production per unit time for maintaining the pressure in the water storage tank increases by about 0.5 times. In order to stabilize the pressure in the water storage tank body, a pressure sensor is specially installed to detect the pressure in the water storage tank body. In the injection process, when the pressure in the water storage tank body is less than 0.65 MPa, the first gas production compensation agent column is started to generate gas compensation, and the pressure in the water storage tank body is kept. And (3) starting a second gas production agent compensation column when the pressure in the water storage tank body is less than 0.65 MPa along with the reduction of the water amount, so as to generate gas compensation and keep the pressure in the water storage tank body. If the pressure in the water storage tank body is continuously more than 0.65 MPa, the gas production agent compensation column is not started.
The theory and experiment of the double-phase flow colliding nozzle prove that the water mist has the best fire extinguishing effect at 400-plus-1000 micron particles, namely certain kinetic energy can penetrate through flame outer flame and directly act on flame inner flame, so that the flame energy is reduced, air can be isolated, the flame is prevented from expanding, and the fire extinguishing effect is achieved. Therefore, the system adopts the spray head to develop a double-phase flow colliding spray head for the company. The nozzle adopts 6 groups of 1 mm collision spray holes, 400-plus-1000-micron water mist is generated through high-pressure collision, and high kinetic energy is kept to achieve the fire extinguishing effect.
