Fire prevention method for foaming agent packaging

Abstract

The invention relates to the technical field of fire prevention for foaming agent packaging, and discloses a fire prevention method for foaming agent packaging. The fire prevention method comprises the steps that (1) air is heated by a heater, washed qualified ADC powders are put into a feeding hopper, the washed qualified ADC powders are sucked into an air blower together with the hot air, and the materials are crushed by the air blower and then sent into a drying tower for drying; and (2) the dried qualified ADC powders are fed into an ADC stock bin after being subjected to graded trapping through a first-stage cyclone and a second-stage cyclone, and an ADC feeding valve controls the feeding of the materials. According to the fire prevention method for the foaming agent packaging, a temperature detection element is arranged to detect the temperature in the ADC stock bin, when the materials are accumulated in the ADC stock bin, the temperature rises accumulatively, and after a fire occurs, the temperature in the ADC stock bin rises; and when the temperature in the ADC stock bin is higher than 80 DEG C, the ADC feeding valve is closed, the air blower stops running, a fire-fighting water valve is opened at the same time, then a fire-fighting water supply pipe sprays fire-fighting water into the ADC stock bin for cooling and fire extinguishing, and the spreading of the fire disaster can be effectively prevented.

Description

technical field [0001] The invention relates to the technical field of foaming agent packaging fireproofing, in particular to a method for foaming agent packaging fireproofing. Background technique [0002] Foaming agent is a substance that makes the target substance form pores. It can be divided into three categories: chemical foaming agent, physical foaming agent and surfactant. Chemical foaming agent can release gases such as carbon dioxide and nitrogen after thermal decomposition. , and form pores in the polymer composition, the physical blowing agent is the foam pores, which are formed by the change of the physical form of a certain substance, that is, the expansion of compressed gas, the volatilization of liquid or the dissolution of solid The compound and foaming agent have high surface activity, which can effectively reduce the surface tension of the liquid, arrange the double electron layer on the surface of the liquid film to surround the air, form bubbles, and the...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a fire-proof method for foaming agent packaging, which has the advantage of good fire-proof effect, and solves the problem that the foaming agents commonly used at present are all first-class flammable solids. There is a danger of combustion and explosion in contact with oxidants. The foaming agent needs to be dried during the production process. The foaming agent accumulates in the silo, and the temperature accumulates, which is prone to fire accidents in daily production
