Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings. It is to be understood that the description of the embodiments herein is for purposes of illustration and explanation only and is not intended to limit the invention.

In the present invention, unless otherwise specified, the use of directional terms such as "one end, the other end" and the like generally refer to the orientation shown in the drawings.

According to the utility model discloses an aspect, as shown in fig. 1, provide one ammonia automatic spray system, ammonia automatic spray system includes inductive probe 1, alarm control case 2, power supply box 3, shower nozzle 4 and inlet channel 5, inductive probe 1 is arranged in the concentration of ammonia in the detection indoor environment, can adopt the well-known probe that has the detection gas concentration among the prior art, inductive probe 1's quantity sets up according to the size of indoor actual area. Alarm control case 2 passes through the pipe connection inductive probe 1 reaches inlet channel 5, solenoid valve 7 sets up alarm control case 2 with the junction of inlet channel 5, the one end of inlet channel 5 is used for rivers to flow in, and the other end is provided with shower nozzle 4, the quantity of shower nozzle 4 sets up according to indoor actual area's size. The inductive probe 1 is connected with the power box 3.

During daily work, the power box 3 is always in an open state and supplies power to the inductive probe 1 at any time, and the inductive probe 1 also monitors the concentration of the ammonia gas in a room at any time. When ammonia leakage occurs in a room or a factory building where an ammonia gas cylinder is stored in an ammonia gas supply station to cause the concentration of ammonia in the environment to rise to a certain value, the inductive probe 1 can immediately detect the concentration of ammonia in the environment, and if the concentration exceeds the national or enterprise safety standard, the inductive probe 1 immediately transmits a signal to the alarm control box 2 through the pipeline 6. The alarm control box 2 receives a signal and then immediately transmits the signal to the electromagnetic valve 7 through the pipeline 6, the electromagnetic valve 7 can be used for controlling the opening and closing of the water inlet pipeline 5, when the electromagnetic valve 7 receives a signal that the concentration of ammonia exceeds the standard, the electromagnetic valve 7 is opened, external water flow such as tap water can flow in through one end of the water inlet pipeline 5 and then flows into the spray head 4, the spray head 4 starts to carry out continuous spray operation indoors, when the spray operation is carried out for a certain time, the concentration of the ammonia in the room starts to decline after the spray operation starts because the ammonia has the chemical property of being easily soluble in water, when the inductive probe 1 detects that the concentration of the ammonia in the indoor environment is reduced below the safety standard, a new signal is transmitted to the alarm control box 2 through the pipeline 6, and the alarm control box 2 transmits the signal to the electromagnetic valve 7 through the pipeline 6 after receiving the new signal, after the electromagnetic valve 7 receives the signal, the electromagnetic valve 7 is closed, water flow can not flow into the spray head 4 again, so that the spray head 4 is controlled not to perform spraying operation, and the control of the indoor ammonia concentration is realized through the spraying operation. Through the utility model discloses, not only can carry out real-time supervision to the concentration of ammonia in the indoor environment, the system can also judge automatically whether need spray operation and automatic control spray the volume what, can guarantee that the measurement personnel get into again after indoor ammonia concentration reaches the safety standard indoor and examine and subsequent processing to the place of ammonia leakage for the measurement personnel can not directly carry out the ammonia environment that the concentration exceeds standard and cause harm to the human body.
