Problems solved by technology

Although this safety method is relatively simple, there is less monitoring of the liquid ammonia tank. If there are no leaks and other problems, tap water is always used for spraying, which is a waste of water resources.
If there is a security risk, there is no way to know, so this method is relatively backward and the security is poor

Embodiment Construction

[0019] The preferred technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0020] Such as figure 1 As shown, a liquid ammonia storage safety alarm device of the present invention includes a temperature sensor 1 fixed on the liquid ammonia tank, a concentration sensor 2 located outside the tank, and a pressure sensor 3 connected to the pipeline of the liquid ammonia tank The temperature sensor 1, the concentration sensor 2 and the pressure sensor 3 are respectively connected through the circuit control circuit, and the spraying device 4 used for cooling after reaching the induction condition is provided. The temperature sensor 1 usually contacts the tank through a multi-point contact method. body, the concentration sensor 2 generally has sensing contacts located around the tank body, and the pressure sensor 3 is set in the pipeline of the tank body to directly measure the internal pressure.

Abstract

The invention discloses a liquid ammonia storage safety alarm device. The liquid ammonia storage safety alarm device comprises a temperature sensor fixed on a liquid ammonia tank, a concentration sensor arranged outside the liquid ammonia tank, a pressure sensor communicated with a liquid ammonia tank pipeline, and spray equipment connected with the temperature sensor, the concentration sensor and the pressure sensor by circuit control lines respectively and used for cooling after a sensing condition is met. Compared with the prior art, the liquid ammonia storage safety alarm device can achieve the functions of alarming and automatic spraying cooling and diluting under the cooperation action of the temperature sensor, the concentration sensor and the pressure sensor, and also can improve the liquid ammonia storage safety.

Description

technical field [0001] The invention relates to an integrated safety alarm device, in particular to a liquid ammonia storage safety alarm device. Background technique [0002] Liquid ammonia is a colorless liquid with a strong pungent odor. As an important chemical raw material, ammonia is widely used. For the convenience of transportation and storage, the gaseous ammonia is usually pressurized or cooled to obtain liquid ammonia. Ammonia is easily soluble in water and forms an alkaline solution of ammonium hydroxide when dissolved in water. The solubility of ammonia in water at 20°C is 34%. [0003] Store in pressure cylinders or tanks. Liquid ammonia is widely used in industry, and it is corrosive, volatile, flammable and explosive, so its chemical accident rate is quite high. [0004] The existing safety assurance technology only uses water spray to absorb the leaked ammonia gas from the steel cylinder, and cools down the steel cylinder to prevent the gasification o...
