Description
Technical Field
The invention relates to the technical field of CAFS pipeline detection, in particular to a compressed air foam detection system applied to a three-side firewall building.
Background
CAFS is a compressed air foam system, and is one of fire extinguishing modes. Water, high-efficiency foam concentration and compressed air are automatically mixed according to a required proportion through control, a large amount of fine fire-extinguishing foam is generated through the stirring and blowing actions of the compressed air, and the compressed air foam is sprayed to a fire source through a high-pressure fire pump to extinguish fire. It has the following main characteristics:
(1) High fire extinguishing efficiency and safety. CAFS adopts the powerful spraying mode of compressed air, high-efficient concentrated foam fire extinguishing liquid and water trinity, attaches the water film heat absorption area on the foam big, the heat absorption capacity is strong, and the foam has isolated air's effect again simultaneously, and chemical chain reaction can be prevented to dedicated foam liquid, and fire extinguishing effect is better than traditional foam, water tank formula fire engine far away. The foaming agent can obviously reduce the tension among water molecules, so that the foam liquid has strong permeability and can permeate into the combustion objects, and the fire extinguishing time is greatly shortened. Because the cooling is rapid, the risk of afterburning is reduced, and the formation of smoke is reduced, therefore, the fireman does not have the burden of high temperature, and the danger of the fireman can be greatly reduced.
(2) The water and the foam are used less, and the use cost is low. Because the water is completely attached to the surface of the foam, the foam water-saving fire truck completely plays a role in absorbing heat, reduces the loss of water, overcomes the defect of large water consumption of the conventional water tank type fire truck, and can save more than 80 percent of water compared with the conventional water tank type fire truck under the same fire extinguishing condition, thereby being particularly suitable for urban and rural areas which lack water early.
Based on the characteristics, the CAFS is deployed in many important places. In order to ensure that the CAFS meets the requirement of high-order release flow in practical application, various performances of the CAFS pipeline and various components thereof are regularly detected, such as a test of the high-order release flow. The valve hall of a converter station is mainly used for buildings for arranging converter valves and related equipment, and is the core of the building of the converter station. Because the current conversion operation generates a large amount of heat in the valve hall, a CAFS pipeline can be arranged besides the measures of cooling through ventilation, air conditioning and the like. However, when the flow rate at the tail end of the CAFS pipeline in the valve hall is detected, if the real simulation is adopted, the sprayed foam liquid or water can cause pollution and damage to equipment in the valve hall, and the cleaning work is very difficult.
At present, detection technologies for the quality of the foam liquid and other parameters are mature, but simulation or detection on a small-sized mobile foam liquid system is mostly adopted. The compressed air foam detection device disclosed in the application number CN201420135105.3 comprises a compressed air pipeline, a water pipeline I, a foam liquid pipeline I, a water pipeline II and a foam liquid pipeline II which are transversely and horizontally arranged, wherein a compressed air flowmeter, a water flowmeter I, a foam liquid flowmeter I, a water flowmeter II, a foam liquid flowmeter II, a compressed air pipeline, a water pipeline I, a foam liquid pipeline I and a foam liquid pipeline II are correspondingly arranged on each pipeline, and both ends of the foam liquid pipeline I and the foam liquid pipeline II are hollow straight pipes, and both ends of each hollow straight pipe are axially opened along a pipe body; the water pipeline II is a hollow straight pipe, the two ends of the water pipeline II are respectively and outwards symmetrically extended out of the water inlet and the water outlet in an inclined mode at the two sides of the end part, the two ends of the water pipeline II are symmetrically arranged in a Y shape, and the compressed air flow meter, the water flow meter I, the foam liquid flow meter I, the water flow meter II and the foam liquid flow meter II are in signal connection with the control box. The device can accurately measure the relevant parameters of the system, is not interfered by external climatic factors and human factors when receiving the foam liquid, and can carry out inspection and judgment more scientifically and accurately. The device detects to the foam liquid system on the fire engine, is not suitable for the foam liquid that lays in the building to detect, especially lays the condition of having multiple important equipment in the building.
