Regeneration method of protein foam extinguishing agent

Abstract

The invention discloses a regeneration method for a protein foam extinguishing agent which consists of the following steps: (1) the inactive protein foam extinguishing agent is placed into a reaction kettle with the temperature being controlled between 60 DEG C and 70 DEG C; (2) under the situation of mixing, surfactant, salt-mixture, inorganic ammonia salt and one or more of mixtures of organic ammonia salt are added to dissociate the protein for the sedimentation of the protein, the mixing time is 30min to 60min; (3) sedimentation is rested for 30min to 60min; (4) a clear liquid is taken; (5) the clear liquid is heated in the reaction kettle with the temperature being controlled between 35 DEG C and 50 DEG C; (6) stabilizer and preservative are added into the clear liquid under the situation of mixing, the mixing time is 30min to 60min; (7) resting; (8) the clear liquid is taken so as to acquire the regenerated protein foam extinguishing agent. The regeneration method of the protein foam extinguishing agent can carry out treatment on the inactive protein foam extinguishing agent and lead various indexes to suit for GA219-1999 requirements, thus realizing the regeneration and secondary utilization of the protein foam extinguishing agent.

Description

technical field [0001] The invention relates to the recycling technology of protein foam fire extinguishing agent. Background technique [0002] In the prior art, the protein foam fire extinguishing agent is mainly composed of hydrolyzed protein, stabilizer, antifreeze and preservative, etc., and its storage period is two years. After two years of storage, the protein foam fire extinguishing agent will mutate and easily form mutant proteins. The protein foam turns black and becomes smelly, so that some main indicators of the protein foam fire extinguishing agent cannot meet the national use standards. The protein foam fire extinguishing agent beyond the storage period must be discarded forcibly, which not only pollutes the environment, but also causes great waste. Contents of the invention [0003] The invention provides a protein fire extinguishing agent regeneration method, which can process the invalid protein foam fire extinguishing agent so that its various indicators...
