Urea hydrolysis fire sprinkler system

Abstract

The invention discloses a urea hydrolysis fire sprinkler system which comprises a sprinkling water supply device, a plurality of urea hydrolysis skid sprinklers and a controller, wherein a water outlet end of the sprinkling water supply device is connected with a water inlet end of each of the urea hydrolysis skid sprinklers; each of the urea hydrolysis skid sprinklers comprises an annular sprinkling pipeline, an ammonia leakage detector and a first pneumatic control valve; the first pneumatic control valves are arranged at water inlets of the annular sprinkling pipelines; the ammonia leakage detectors and the first pneumatic control valves are in electric interlock through interlocking switches; the ammonia leakage detectors are connected with the water outlet end of the sprinkling water supply device; alarm apparatuses are arranged on the interlocking switches; and the ammonia leakage detectors, the first pneumatic control valves and the alarm apparatuses are electrically connected with the controller. The urea hydrolysis fire sprinkler system has the following beneficial effects: remote control of sprinkling is realized without field operation of an operating worker, and direct contact with ammonia gas is avoided; point-to-point and face-to-face sprinkling is realized according to the area requiring sprinkling, so that fire fighting water volume is saved, leaking ammonia gas is effectively diluted, and the coverage area of the sprinkled area is complete.

Description

technical field [0001] The invention relates to the technical field of fire protection, in particular to a urea hydrolysis fire sprinkler system. Background technique [0002] In the prior art, using an indoor fire sprinkler system for fire protection has the following disadvantages: [0003] (1) When ammonia gas leaks from skids and accessories, operators must operate on site and cannot be remotely controlled. Since ammonia gas is a toxic gas, it has a corrosive effect on the human respiratory tract and skin, and direct contact may easily cause personal injury; [0004] (2) The fire sprinkler system cannot effectively spray the specific area of ​​the hydrolysis area, so when the system is turned on, all areas must be sprayed, resulting in waste of fire water, and the area covered by the spray is not comprehensive; [0005] (3) The fire sprinkler system cannot detect ammonia leakage in the air, which is prone to danger. Contents of the invention [0006] In order to solv...

Problems solved by technology

[0003] (1) When ammonia gas leaks from skids and accessories, operators must operate on site and cannot be remotely controlled. Since ammonia gas is a toxic gas, it has a corrosive effect on the human respiratory tract and skin, and direct contact may easily cause personal injury;

[0004] (2) The fire sprinkler system cannot effectively spray the specific area of ​​the hydrolysis area, so when the system is turned on, all areas must be sprayed, resulting in waste of fire water, and the area covered by the spray is not comprehensive;

[0005] (3) The fire sprinkler system cannot detect ammonia leakage in the air, which is prone to danger
