At this time, bromine continuously enters the bromine storage tank from the bromine feeding pipe 11 through the discharging pipe of the bromine storage tank under the action of the pressure difference between the bromine storage tank and the emergency tank, and after the bromine is transferred from the emergency tank to the bromine storage tank, the first valve body 12, the third valve body 33 and the nitrogen compressor 32 are closed. In the whole bromine pressure delivery process, the air inlet of the bromine storage tank is required to be always in an open state, so that the bromine storage tank and the external air pressure are kept balanced, and the smooth bromine pressure delivery is ensured.

This embodiment adopts the nitrogen pressure to send the mode, shifts bromine to the bromine storage tank from emergent jar, avoids air and bromine direct contact, and labour saving and time saving improves work efficiency. The buffer tank 34 of the present embodiment serves to stabilize the gas pressure and reduce the fluctuation of the pressure. In the embodiment, nitrogen is adopted, so that on one hand, air is prevented from being in direct contact with bromine; on the other hand, after the bromine is conveyed from the emergency tank to the bromine storage tank in a pressing way, the emergency tank is filled with nitrogen, and the nitrogen isolates air from the inner wall of the tank body 1 of the emergency tank, so that the service life of the emergency tank is prolonged.

Example 4

As shown in fig. 2, this embodiment is further defined by any one of embodiments 1 to 3, where the first gas pipeline 21 is further provided with a bromine gas absorption tower 24, so as to absorb the volatilized bromine gas, thereby ensuring the life safety of emergency personnel and avoiding environmental pollution.

Example 5

As shown in fig. 2, this embodiment is further defined as any one of the embodiments 1 to 4, wherein the bromine feed pipe 11 penetrates into the tank 1 in a sealing manner, and the port position of the bromine feed pipe 11 located in the tank 1 is lower than the connection position between the bromine feed pipe 11 and the tank 1. After bromine is transferred from the bromine storage tank to the emergency tank, the connection position between the bromine feeding pipe 11 and the tank body 1 is higher than the liquid level in the emergency tank, so that the connection position between the bromine feeding pipe 11 and the tank body 1 is prevented from being directly corroded and perforated by bromine, and the service life of the emergency tank is prolonged.

Further, the bromine feeding pipe 11 is a straight pipe, and the bromine feeding pipe 11 is obliquely and downwards sealed and penetrates into the tank body 1.

Further, the bromine feeding pipe 11 is in an inverted L-shaped structure and is provided with a bromine feeding horizontal pipe 111 and a bromine feeding vertical pipe 112, and the bromine feeding horizontal pipe 111 and the bromine feeding vertical pipe 112 are communicated with each other in a sealing way; the bromine feeding horizontal pipe 111 is communicated with the bromine feeding vertical pipe 112 after penetrating into the tank body 1 in a sealing way; the bromine feed standpipe 112 is disposed inside the tank 1, and a port of the bromine feed standpipe 112 is near an inner bottom wall of the tank 1. After the bromine is transferred from the bromine storage tank to the emergency tank, the connection position between the bromine feeding pipe 11 and the tank body 1 and the bromine feeding transverse pipe 111 are made to be higher than the liquid level in the emergency tank, so that the connection position between the bromine feeding pipe 11 and the tank body 1 and the bromine feeding transverse pipe 111 are prevented from being directly corroded and perforated by bromine, and the service lives of the emergency tank and part of the bromine feeding pipe 11 are prolonged.

Example 6

The reservoir 42 is used for storing a liquid, which is required to have a density less than that of bromine, which is slightly or poorly soluble in the liquid; the liquid is preferably water. When in use, emergency personnel firstly open the fourth valve body 43 and start the pump body 44, water enters the tank body 1 from the liquid storage 42 through the liquid delivery pipeline 41, falls to the bottom in the tank body 1, and closes the pump body 44 and the fourth valve body 43 when the required water quantity is monitored through the liquid flow sensor 45; the bromine transfer from the bromine storage tank to the emergency tank was then performed as described in example 1. Because the density of water is less than that of liquid bromine, bromine is slightly dissolved in water, and the water in the emergency tank and bromine are layered, a layer of water seal is formed on the bromine, and the bromine is easy to volatilize and toxic, and can be effectively inhibited from volatilizing in a water sealing mode.

When the bromine storage tank is used, water with set temperature can be stored in the liquid storage tank 42 in advance according to the temperature of bromine in the bromine storage tank, and after the water in the liquid storage tank 42 enters the emergency tank, the bromine in the emergency tank exchanges heat with the water in the transferring process of the bromine from the bromine storage tank to the emergency tank, and finally the bromine reaches the temperature meeting the requirement. When the temperature of the bromine in the bromine storage tank is too low, a heater in the liquid storage tank 42 can be started to quickly heat the water so as to reach the set temperature.

For example, the gas port 2, the liquid level meter port 3, the pressure transmitter port 4 and the liquid inlet port 7 are arranged at intervals at the top of the tank body 1, the top is not necessarily provided with a specific direction, and after the bromine is sucked from the bromine storage tank to the emergency tank, the gas port 2, the liquid level meter port 3, the pressure transmitter port 4 and the liquid inlet port 7 are all arranged above the liquid level in the tank body 1 and are not contacted with each other so as to prevent the bromine from being directly immersed in the bromine and corroded and perforated.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model. For example, the emergency tank is not only suitable for emergency disposal of bromine, but also suitable for emergency disposal of other liquid major dangerous sources, and belongs to equivalent replacement. The second gas pipe 31 is connected in parallel with the first gas pipe 21 and then communicated with the gas port 2, and can be equivalently replaced by: the second gas pipe 31 communicates with the tank 1 through a first gas port, and the first gas pipe 21 communicates with the tank 1 through a second gas port.
