Ask what a fire blister is and what is a fire bubble?

The fire water cannon is used in the normal large space, and the infrared beam or optical surface detector alarm system is used for fire detection and fire extinguishing treatment.

With the image-based fire detection and alarm system as the core, the conventional fire alarm linkage control system is supplemented to realize the distributed control-centralized management mode. Once a fire breaks out at the scene, the information processing host sends out an alarm signal, displays the image of the alarm area, and automatically turns on the video recorder for recording; At the same time, through the linkage console, the automatic fire cannon is activated in a human-machine collaborative way to extinguish the fire at a fixed point.

How can there be fire blisters? Only fire water cannons! It is usually set outdoors, fixed on a pedestal, and aligned with the exterior wall of the upper part of the building.

When it needs to be used, the high-pressure water pump must be activated to pressurize it first, and then it can be sprayed very high and far, which is essentially the same as the water cannon on a coast guard ship.

The fire water cannon is a fire extinguishing equipment that uses water as the medium to extinguish fires from a distance.

Principle: Components and functions:

1. Water supply system.

It is mainly composed of a water source, a fire pump, a high-level water tank or an air pressure stabilizing device, a water pump adapter and a pipeline, and its purpose is to provide a fast and sufficient water source for the device.

Second, the implementation system.

It is composed of intermediate actuators such as fire extinguishing devices, power supply devices, and automatic fire alarm devices, that is, when a fire occurs, the relevant components that execute fire extinguishing and alarm actions.

3. Control system.

It is composed of linkage control cabinet and regional control box, system power supply controller, and computer fire monitoring system. Its purpose is to control the water supply system and the actuation system, and can flexibly realize various operations such as manual, automatic, on-site and fire center. Effectively complete a series of actions from the discovery of the fire to the extinguishing of the fire.

And the automatic tracking and positioning jet fire extinguishing system can be directly connected with the automatic fire alarm center through the input module and the input and output module to ensure the integrity of the fire alarm system.

Fire foam is a kind of foam fire extinguishing equipment used to extinguish fires, and its principle is to use the isolation effect of foam to effectively prevent the fire from developing in the surrounding direction, and control the burning area in water in a short time, so as to protect the safety of people and other property. The fire fighting foam of Zhejiang Jinruiheng Fire Protection Department is composed of a foam generator and a control box The generator pushes the foam liquid to the control box through compressed air, in which the foam liquid is stored in a device called a foam tank, and the foam liquid must be in a foam state when it is stored, otherwise it cannot produce foam. The range of applications is very wide and can be applied to different types of combustion accidents.

In the event of a fire, the fire-fighting foam can quickly block the burning area in a short period of time, isolate the oxygen and cool the fire source, thus effectively reducing the spread of the fire and the expansion of the burning. The use of firefighting foam equipment requires regular maintenance and upkeep to ensure that it functions properly and can maximize its extinguishing effectiveness.

The commonly used chemical foam fire extinguishing agent is mainly a foam formed by the interaction between acidic salts (aluminum sulfate) and alkaline salts (sodium bicarbonate) and a small amount of foaming agent (plant hydrolyzed protein or licorice powder) and a small amount of stabilizer (ferric chloride).

The chemical foam extinguishing agent generates a large amount of carbon dioxide gas after the action, and it reacts with the blowing agent to form many bubbles. The foam is low density and sticky, and can cover the surface of the burning object to keep out the air. At the same time, carbon dioxide is an inert gas and does not support combustion.

This is used for oil and other venues, and the airport is also equipped.

There are several types of foam, generally used are ordinary foam fire extinguishing agent and class A foam, search it on the Internet.

Foam fire extinguishing is a fire extinguishing method that uses water and foam liquid mixed and sprayed to form a large number of bubbles, which is used to cover the surface of combustibles such as liquid, and isolate oxygen and cool down as a fire extinguishing mechanism.

Class B foam fire extinguishing agent is a new type of high-efficiency compressed air foam fire extinguishing agent. Its main advantages are fast fire control speed, high water use efficiency in the fire field, significant effects of heat insulation, radiation prevention, and anti-re-ignition, which can greatly reduce the loss of water stains at the fire site.

Anti-soluble foam For water-soluble flammable and flammable liquids, this fire extinguishing agent has good stability and can resist the destruction of water-soluble flammable and flammable liquids. When this insoluble foam liquid is mixed with water and produces foam under mechanical action, a kind of film is formed on the foam wall, which can effectively prevent the water-soluble solvent from absorbing the water in the foam, thereby protecting the foam, so that the foam is better covered on the liquid surface of the water-soluble solvent and plays a role in extinguishing the fire. In addition, the water precipitated from the anti-solvent foam can also have a dilution effect on the surface of the water-soluble solvent, which is also beneficial for extinguishing fires.

This is to prevent the pressure of the sprinkler pump from being insufficient to effectively extinguish the fire and fire hydrant

Fire hydrant, officially known as fire hydrant, is a fixed fire protection facility, the main role is to control combustibles, isolate combustibles, and eliminate ignition sources. It is divided into indoor fire hydrants and outdoor fire hydrants. Fire protection systems include, outdoor fire hydrant system, indoor fire hydrant system, fire extinguisher system, and some will also have automatic sprinkler system, water cannon system, gas fire extinguishing system, fire detection system, water mist system, etc.

The fire hydrant is mainly used by fire trucks to draw water from the municipal water supply pipe network or outdoor fire water supply pipe network to extinguish the fire, and can also be directly connected to the hose and water gun to extinguish the fire. Therefore, the indoor and outdoor fire hydrant system is also one of the important firefighting facilities for fire fighting.

Location: 1. The fire hydrant should be placed in a public shared space such as a corridor or hall, and it is generally in the wall of the above-mentioned space, no matter what kind of decoration it is made, it is required to be marked with eye-catching (indicated"Fire hydrants"and shall not set up obstacles in front of it to avoid affecting the opening of the fire hydrant door.

2. The fire hydrant is isolated in the room (such as the box), which does not meet the regulations of fire protection and is not conducive to the timely rescue of fire personnel.

Under certain conditions, the fire water cannon pump should be set independently, if the sprinkler pump is used in the case of sufficient sprinkler pump pressure, the fire pump can only be used if it is insufficient (generally in the building with a roof water tank, the sprinkler pump pressure can be satisfied). In principle, it should be a sprinkler pump, and I have managed a number of projects using fire water cannons, which are basically set up according to this principle, and have successfully passed the fire inspection, acceptance and put into use. The actual test effect is very good.

Fire hydrant The spray pressure is not enough.
