Test platform for conveying dry powder extinguishing agent

Abstract

The invention relates to a test platform for conveying a dry powder extinguishing agent. A fluidization blowing conveying device, a pipeline test device and a recycling transferring device are included, wherein the fluidization blowing conveying device is used for generating the dry powder extinguishing agent for injection; the pipeline test device is arranged at an outlet of the fluidization blowing conveying device, provided with a pipeline joint capable of being assembled and disassembled, and used for installing a conveying pipeline to be tested; and the recycling transferring device is arranged at an outlet of the pipeline test device, and can be used for collecting the dry powder extinguishing agent, separating various components in the dry powder extinguishing agent, and transferring the dry powder components which are separated out to the fluidization blowing conveying device. Based on the above technical scheme, the embodiment of the invention can at least achieve recycling ondry powder, and therefore the cost of a dry powder transporting test is lowered, and the personnel and environment safety in the test process is guaranteed.

Description

technical field [0001] The invention relates to the field of fire protection, in particular to an experimental platform for dry powder fire extinguishing agent delivery. Background technique [0002] The fire-fighting materials represented by dry powder-nitrogen fire extinguishing agent, the dry powder material can produce chemical inhibition and negative catalysis to interrupt the chemical reaction, or form a glassy covering layer under high temperature operation to isolate the burning area, and the high pressure in it Nitrogen can make the dry powder material be ejected uniformly at a certain speed in a fluidized state, and it can also play a certain degree of isolation. Therefore, fire-fighting equipment using dry powder-nitrogen two-phase flow as a fire extinguishing agent can be used to fight flammable liquids (such as oils, liquid hydrocarbons, alcohols, esters, ethers, etc.), combustible gases (such as liquefied petroleum gas, natural gas, coal gas, etc.) etc.) and e...

Problems solved by technology

However, due to the spraying of dry powder fire extinguishing agent, the dry powder will not only cause dust pollution to the environment, but also easily cause serious inhalation injuries to experimenters, so there is currently no safe and reliable experimental platform

In addition, the cost of dry powder fire extinguishing agent is relatively high (about 20,000 RMB / ton). To complete the test on the fluidization effect and transportation of dry powder, repeated spraying is required. The cost of this process is too high, which also leads to the lack of physical size An important reason for the dry powder blowing and conveying test platform
