Title:
FIRE-FIGHTING FOAM FOAMING APPARATUS, SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2024/045249
Kind Code:
A1
Abstract:
A fire-fighting foam foaming apparatus (100), system and method, relating to the technical field of compressed air foam fire suppression, and used for improving the foaming effect of fire-fighting foams. The fire-fighting foam foaming apparatus (100) comprises: an air nozzle assembly (120), comprising a liquid inlet hole (121), an air inlet hole (122), a first air outlet hole (123), and a flow guiding portion (124); the liquid inlet hole (121) being in fluid communication with a first flow path (111), and the liquid inlet hole (121) being located downstream of the first flow path (111); the air inlet hole (122) being in fluid communication with a second flow path (112) and being located downstream of the second flow path (112); and a foam mixing chamber (130), located downstream of the first flow path (111) and the second flow path (112) and in fluid communication with both the first flow path (111) and the second flow path (112); both the first air outlet hole (123) and the flow guiding portion (124) extending into the foam mixing chamber (130); and the first air outlet hole (123) and the flow guiding portion (124) being configured such that the airflow output via the air nozzle assembly (120) flows to different positions in the radial direction of the foam mixing chamber (130). Therefore, the foaming effect is improved.
