Description
Technical field
The utility model belongs to chemical production technical field, and in particular to a kind of liquefied ammonia stocking system.
Background technology
Liquefied ammonia, also known as anhydrous ammonia are a kind of colourless liquids, there is intense irritation smell.Ammonia is as a kind of important change
Work raw material, is widely used, and to transport and storing facility, gaseous ammonia usually is obtained liquid ammonia by pressurizeing or cooling down.Ammonia
It is soluble easily in water, the alkaline solution of formation ammonium hydroxide after water is dissolved in, solubility of the ammonia in 20 DEG C of water is 34%.
Liquefied ammonia is stored in pressure-resistant steel cylinder or steel tank, and cannot be coexisted with substances such as acetaldehyde, methacrylaldehyde, boron more.Liquefied ammonia is in work
It is widely used in industry, there is corrosivity, it is readily volatilized and inflammable and explosive, so its chemical accident incidence is quite high.
The ammonia that existing safeguard technology only reveals steel cylinder with water spray absorbs, and cools down to steel cylinder,
It prevents high temperature from causing liquid ammonia gasification, causes steel cylinder pressure is excessive to explode.Therefore the originally necessary round-the-clock unlatching of water spray,
If it during phenomena such as cutting off the water, cannot ensure safely.This secured fashion is although fairly simple, but to the monitoring of ammonia tank compared with
It is few, it is a kind of waste to water resource if existing without the problems such as leakage always using originally water spray.If there are security risk also without
From it is found that therefore the method more falls behind, safety is also poor.
Utility model content
The purpose of this utility model is that in view of the deficiencies of the prior art, now provide a kind of real-time monitoring alarming, anti-ammonia
Leakage, the liquefied ammonia stocking system of blast protection.
In order to solve the above technical problems, the technical solution adopted in the utility model is：A kind of liquefied ammonia stocking system, innovation
Point is：Including two independent liquid storage cylinders, it is connected between the liquid storage cylinder by gas-liquid equilibrium pipe, the storage ammonia cylinder interior peace
Equipped with pressure transmitter, liquid level sensor, Voltage force table, temperature sensor and super liquid level alarm, the storage ammonia cylinder and tail gas
Absorption system is connected, and toxic air alarm device is provided with by the storage ammonia cylinder, and the storage ammonia cylinder passes through feed pipe with liquefied ammonia tank vehicle
It is connected, is equipped on the feed pipe and unloads ammonia pump, the ammonia pump that unloads is connected with liquid level sensor.
Further, it is equipped in the tail gas absorbing system into water motor-driven valve, the tail gas absorbing system and storage ammonia cylinder
Between be connected with safety valve, the water inlet motor-driven valve is connected with pressure gauge and pressure transmitter.
Further, the toxic air alarm device is connected with controller, and the controller is equipped with audible-visual annunciator.
Further, the gas-liquid equilibrium pipe is connected with having tank car gas phase pipe and doing ammonium hydroxide system.
Further, it the liquefied ammonia tank vehicle and unloads filter is installed between ammonia pump.
The beneficial effects of the utility model are as follows：
（1）The utility model by storage ammonia cylinder by setting poisonous gas leakage alarm, when there is leakage situation to occur, factory
Value personnel can have found at the first time, reduce the generation of dangerous situation；
（2）The utility model can be incited somebody to action by installing pressure transmitter, temperature sensor, liquid level sensor on liquid storage ammonia
In temperature, pressure, level parameter remote transmission to controller in storage ammonia cylinder, when parameter exceeds setting value, controller occurs
Alarm can monitor temperature, pressure and liquid level in storage ammonia cylinder in real time；
（3）The utility model is attached by will unload ammonia pump with storing up the liquid level sensor on ammonia cylinder, when liquid level exceeds
During setting value, unloading ammonia pump will be stopped immediately, it is therefore prevented that liquefied ammonia is overflowed from storage ammonia cylinder；
（4）The utility model sets pressure gauge on storage ammonia cylinder, and pressure gauge and safety valve are attached, when in storage ammonia cylinder
Pressure when being more than the setting value on pressure gauge, safety-valve can automatic take-off, and discharge ammonia, it is therefore prevented that store up ammonia cylinder internal cause pressure
Power is excessive, and explodes；
（5）The utility model is absorbed the ammonia of release, it is therefore prevented that ammonia by being connected with tail gas absorbing system safety valve
Gas pollutes environment.
