Abstract
The invention provides an anti-powder blocking lower inflatable structure of a gas storage bottle type dry powder extinguishing system. The structure includes an inflation tube; a large diameter part formed at the lower part of the inflation tube, and an extension section extending downward in the large diameter part of the inflation tube; and also a reception bowl connected right below the extension section. The extension section extends into the reception bowl, the edge of which is in connection with the inner side wall of the large diameter part. A seam exists between the reception bowl and the inner top wall of the extension section and the large diameter part. A vertically communicated channel is formed on the edge of the reception bowl, and is communicated with a air duct below. Therefore, the large diameter part, the extension section and the reception bowl form a ventilating bent path. A dry powder extinguishing agent falls into the reception bowl through the inflation tube, and cannot turn around and bypass the upper edge of the reception bowl to enter the air duct and an air inlet tube, thus avoiding powder blocking of the air duct and the air inlet tube. During fire extinguishing, the driving gas nitrogen bypasses the upper edge of the reception bowl through the channel and overcomes the resistance of the dry powder extinguishing agent to inflate and pressurize a dry powder storage tank, so that the lower inflatable structure provided in the invention can effectively prevent powder blocking.
Description
Technical field
The present invention relates to fire-extinguishing apparatus field, be specifically related to the lower inflatable structure that the anti-powder of a kind of air storage bottle-type powder extinguishing system is stifled.
Background technology
The inflatable structure of air storage bottle-type powder extinguishing system common on market mainly contains following two types:
For to open a single circular hole at the top of dry powder storage tank, gas tube inserts this circular hole and extend into the bottom of dry powder storage tank, and driving gas stirs as the powder extinguishing agent of nitrogen to inside and carries out supercharging to dry powder storage tank.There is not the stifled problem of powder in this kind of inflatable structure, but due to gas tube gas vent direction down, driving gas is by the impact exporting powder extinguishing agent below, and driving gas must overcome the resistance of the powder extinguishing agent of gas tube outlet surrounding, just can stir powder extinguishing agent.Make this kind of inflatable structure that driving gas cannot be made to form concentrated gas column, greatly reduce the kinetic energy of driving gas, make the pressurization time of whole system long; And owing to being single gas circuit supercharging, driving gas is made to mix extremely uneven with the gas powder of powder extinguishing agent, be difficult to " boiling " phenomenon forming powder extinguishing agent, and then cause powder extinguishing agent to be easily deposited on to spurt in pipeline, make agent application access denial, powder extinguishing agent surplus ratio is high, and powder extinguishing agent utilization rate is low, and consumption is large.
Another kind of for open single circular hole in the bottom of dry powder storage tank, air inlet pipe stretches into this circular hole, and driving gas to stir powder extinguishing agent as nitrogen and carries out supercharging to dry powder storage tank.First, this kind of inflatable structure does not arrange anti-powder block apparatus, and the powder extinguishing agent in dry powder storage tank is directly fallen in air inlet pipeline, causes powder to block up, and increases the hydrostatic head of powder extinguishing agent, extends the pressurization time of system, adds the danger of fire; Secondly, air inlet pipeline is single gas circuit supercharging, " boiling " poor effect of powder extinguishing agent, there is powder extinguishing agent equally to be easily deposited on and to spurt in pipeline, make agent application access denial, powder extinguishing agent surplus ratio is high, powder extinguishing agent utilization rate is low, the problem that consumption is large.
Given this, inventor furthers investigate the problems referred to above, then has this case to produce.
Summary of the invention
The lower inflatable structure that the anti-powder of air storage bottle-type powder extinguishing system that the object of the present invention is to provide a kind of not easily generation powder to block up situation is stifled.
