Fire Technology Product Introduction

1 smoke exhaust equipment - pneumatic smoke machine

As early as in 2009, electromechanical smoke exhauster was a common smoke exhaust device for public security firefighting units, but its disadvantage was that it could not be used without a power source and in flammable and explosive places. Centrifugal gasoline powered smoke evacuators are prone to gasoline leaks and extinguish due to high temperature and oxygen deficiency at the fire site. Hydraulic smoke exhauster is a new type of intrinsically safe explosion-proof fire - fighting equipment with smoke exhaust function and smoke elimination function; but in practical application process, especially in special fire situations where water cannot be saved, such as libraries and computer rooms, Archives, etc., can easily cause water damage, resulting in irreversible consequences.

Compared with electromechanical smoke exhauster and water driven smoke exhauster, pneumatic smoke exhauster has the following features:

(1) Use safety, widely used. Since the air source of the smoke evacuator can be connected to the fan through an arbitrarily long trachea, tees, valves, and power converters, the air source can be placed away from areas with flammable and explosive dangers, and the smoke evacuation device can be installed. It can be safely used in places where smoke is needed. The products are particularly suitable for various occasions such as flammable and explosive, high-rise buildings, underground buildings, subway tunnels, industrial and mining enterprises.

(2) It is easy to move and exhaust smoke. The product is small in size, light in weight, easy to push, and can also be hung. It will not cause secondary damage to the place where smoke is needed, and the effect of smoke exhaust is good. The amount of smoke can reach 4 000 to 6 000 m3 / h .

(3) Convenient and practical, low cost. There are many options for the gas supply of the smoke exhauster, which can be either an inflatable gas cylinder or an external pneumatic pump . It can also be directly connected to the gas pump of the vehicle, and the cost is only the same type of motorized smoke exhauster and water-driven row. A quarter of the smoke machine has a high promotion value.

2 vehicle gas leak alarm

In recent years, due to the requirement of environmental protection, domestic taxis and buses have become more and more used as a driving force for natural gas. However, natural gas is a kind of flammable and explosive gas. After a leak, it is prone to explosion and fire, threatening people's safety. Become a security risk.

The gas leak alarm for vehicles is designed and developed for gas vehicles and is suitable for various oil-to-gas vehicles. This type of alarm is mainly composed of an intrinsically safe gas detector, a car alarm connection assembly, and a vehicle alarm. It monitors the gas concentration in the space through the “detector” and transmits the processed signal to the controller through the “connection assembly”. The product is dustproof, moistureproof, air purifying and fault detection. It can be installed near the engine and gas tank. It can be widely used in taxis and buses to improve the safety factor of gas vehicles. Small cars are generally installed 2 only.

3 fire monitor

GRS PSKDY Wireless Mobile Electronic Control Fire Monitor

The wireless mobile electronically controlled fire monitor is a high-end product used in explosive environments and is mainly used for fire detection and fire extinguishing in explosion-hazardous locations.

The main advantage:

(1) The non-contact fire detection method compensates for the gap of fire detection in the outdoor open space explosion environment.

(2) The active visual alarming method realizes all-directional dead-end fire detection in the fire protection area and integrates with the security monitoring system.

(3) With explosion-proof, dust-proof, waterproof and other functions, it can be widely used in explosive gas atmospheres. For example: petroleum, chemical, nuclear industry and other flammable and explosive places. The explosion protection category is ExdlIBT6 .

(4) Adopt unique image processing technology to make fire detection more intuitive and reliable.

(5) beautiful appearance, strong and durable, can be. Use at 40 to 85 °C and various corrosive environments.

4 environmentally friendly compressed air foam fire extinguishers

The environmentally friendly compressed air foam fire extinguisher incorporates rocket jet technology and a new concept of fire extinguishing. Special nozzles and compressed air injection systems are used to mix the fire extinguishing agent and compressed air to form a uniform ultra-fine foam for long-range fire extinguishing. Fire fighting capability and speed are suitable for extinguishing solid and liquid fires.

The product has the characteristics of light weight, easy to carry, high efficiency and water saving, high fire extinguishing efficiency, and small damage to property after fire extinguishing. In particular, the fire extinguishing agent adopts an environment-friendly foam and can be completely degraded within 12 hours . It is non-pollution to the environment and is very suitable for fighting fire accidents such as traffic accidents, tunnels, forests and ships.

5 automatic fire extinguishing device

The fire extinguishing device consists of a plastic container, an extinguishing agent, a lead wire, an initiator, and a handy handle. In the event of a fire, open flames come in contact with the leads. The initiator activates the fire extinguishing device. The fire extinguishing device ejects the extinguishing agent. It functions as an oxygen barrier, cooling, and covering. It can quickly control the fire and extinguish the fire.

Water extinguishing device

After the water fire extinguishing device contacts the open flame, the initiator is activated, so that the entire fire extinguishing device is opened and the fire extinguishing agent is sprayed out in a mist, so that the fire can be quickly eliminated. The fire extinguishing device can be started automatically, without complicated operation, can be thrown ( safe for operator protection ) , can be fixedly installed, no pollution, and the fire extinguishing efficiency is greatly improved.

Foam fire extinguishing device

Foam fire extinguishing device

The foam fire extinguishing device used in the foam fire extinguishing device has the characteristics of anti-solvent, high efficiency, energy saving, environmental protection, universal, multi-functional, etc., and has a long shelf life, no "three wastes" for production, and no "three harms" for use. It is a multi-functional environmental protection foam. Extinguishing agent. In the event of a fire, the open flame contacts the lead wire, the initiator activates the fire extinguishing device, the fire extinguishing device ejects the multifunctional foam fire extinguishing agent, and the foam fire extinguishing agent is instantaneously emitted, which functions as an oxygen barrier, cooling, and covering, and can quickly control the fire to extinguish the fire.

6 Skyscraper Escape Round

The Skyscraper Escape Wheel overcomes the defects of the existing high-rise escape equipment and is designed with reasonable and simple operation. It mainly relied on a strong enough long rope to smoothly transport trapped people from the tall building to the ground.

Inventor of the Ferris wheel is a floor to escape • named Kevin Stone (KevinStone) plastic surgeon. The tragedy of the “ 9 • 11 Incident” inspired him to develop a simple and practical high-rise escape device. He was inspired by the fishing line and spent 6 years, costing 33 . 50,000 US dollars, finally successfully developed this kind of skyscraper escape wheel. The Ferris wheel is designed with a centrifugal braking system that automatically controls the speed and frequency of descent. The rope of the escape wheel protrudes from a spool and is then wrapped around a shaft connected to the brake device. As the spool rotates, a set of brake pads will exert pressure on the inner edge of the brake box and will be used smoothly and slowly. The person lays down. If this automatic braking system fails, the escape wheel is also equipped with a manual spare brake lever. In use, you need only open a drawer escape sized box, the one with Dupont Kevlar (KEVLAR) fibers ropes made on a secure robust connection point or object, and then the safety harness similar garment sleeve On the body, open the window and let it slip. It can be up to 100 floors away from the ground , and users do not need to receive special training to complete all the preparatory actions less than lmin , from the 100 -storey building to the ground, taking less than 4 minutes .
