Problems solved by technology

Especially the injection of dry powder fire extinguishing agent, because the dry powder is solid, light in specific gravity and fine in particle size, the spray distance is short, and the spray distance requirement cannot be met in many fire scenes, which limits the application of dry powder fire extinguishing agent

Embodiment Construction

[0017] combine figure 1 , the trolley-type composite jet fire extinguishing device of the present invention takes the trolley 1 as a carrier, and a gas cylinder 2, a water / foam tank 5 and an ultrafine dry powder tank 8 are arranged on the trolley 1, and the gas in the gas cylinder 2 is decompressed The valve 3 and the air pipeline 4 enter the water / foam tank 5, and the water and the foam premix in the water / foam tank 5 are pressed into the inlet of the injection device 11 through the water pipeline 7, and the ultrafine dry powder in the ultrafine dry powder tank 8 Enter the inlet of the injection device 11 through the powder outlet valve 9 and the dry powder pipeline 10, and spray water and ultrafine dry powder through the injection device 11 at the same time. The safety valve 6 protects the water / foam tank 5 from overpressure. The invention realizes the simultaneous spraying of water into fine water mist and superfine dry powder, which greatly improves the fire extinguishing ...

Abstract

The invention relates to a wheeled combined jet fire extinguisher which is characterized in that a wheeled cart is taken as a carrier; a gas cylinder, a water tank / foam tank and a superfine dry power tank are arranged on the wheeled cart; the gas in the gas cylinder enters the water tank / the foam tank through an air relief valve and a gas pipeline; the prefixed liquid of water and foam in the water tank / the foam tank is pressed in the inlet of a jet device through a water pipeline; the superfine dry powder in the superfine dry powder tank enters the inlet of the jet device through a powderdischarge valve, a dry powder pipeline; and the water and the superfine dry powder are jet out simultaneously. According to the invention, the water and the dry powder are organically combined, thus achieving compatible properties and complementary advantages. The wheeled combined jet fire extinguisher has extremely fast speed of extinguishment, and extinguishes fire almost instantly within a certain range.

Description

technical field [0001] The invention belongs to a fire extinguishing device, in particular to a cart-type compound jet fire extinguishing device. Background technique [0002] Existing fire extinguishing technology generally uses fire extinguishing agents such as water, foam liquid, and dry powder to extinguish fires. The fire extinguishing agent is delivered to the spray gun or cannon through a single pipeline. The liquid becomes a naturally formed ordinary foam through contact with the atmosphere, and the dry powder is directly sprayed to the fire scene. [0003] Existing cart-type fire extinguishing devices generally adopt fire extinguishing agents such as water, foam liquid, and dry powder to deliver the fire extinguishing agent to the injection device through a single pipeline, and no matter water, foam, or dry powder all adopt a single fire extinguishing agent to extinguish the fire. [0004] With the development of fire-fighting technology, we found that two or more ...
