Embodiment 1

[0039] Such as figure 1 As shown, the 2-bromo-3,3,3-trifluoropropene filling device of the present invention includes a driving bottle 1, a pressure supplement valve 9, a draft tube 13 and 2-bromo-3,3,3-trifluoropropene Propylene storage tank 15.

[0040] The output port of the drive bottle 1 is communicated with the input port of the pressure reducing valve 2 through a pipeline; the output port of the pressure reducing valve 2 is communicated with the input port of the drier 4 through a pipeline, and a desiccant is housed in the drier 4, The desiccant can be anhydrous calcium chloride. The output port of the dryer 4 is connected with a tee joint 6 through a pipeline, and the three ports of the tee joint 6 are respectively connected to the output port of the dryer 4, the input port of the valve one 7, and the input port of the pressure supplement valve 9; The output port of 7 is communicated with the input port of 2-bromo-3,3,3-trifluoropropene storage tank 15, and the outpu...

Embodiment 2

[0044] This embodiment is improved on the basis of Embodiment 1. Specifically, the device also includes a silica gel heating plate for drying the finished bottle 14, and a thermocouple and a temperature display for adjusting and controlling the heating temperature of the silica gel heating plate. , relay, the thermocouple, temperature display, relay and the silica gel heating plate are connected by electrical lines to form a temperature control system, and the circuit connection mode of the thermocouple, temperature display, relay and the silica gel heating plate is the prior art.

[0045] By placing the finished bottle 14 on the silica gel heating plate, the finished bottle 14 is heated and dried through the silica gel heating plate; the thermocouple is used to measure the heating temperature of the silica gel heating plate, and the heating temperature is displayed and set through the temperature display; Control the heating temperature of the circuit. When the heating tempera...

Embodiment 3

[0048] This embodiment is improved on the basis of Embodiment 1. Specifically, the device also includes a vacuum pump 17 for vacuumizing the finished bottle 14, and the vacuum pump 17 is connected to the fourth port of the four-way joint 10 through a pipeline. On, the pipeline is provided with a valve three 18 for controlling the on-off of the pipeline.

Abstract

The invention discloses a 2-bromo-3,3,3-trifluoropropene filling device and method and relates to the technical field of fire-fighting. The device comprises a driving cylinder, a pressure reducing valve, a drier, a flow guiding pipe and a 2-bromo-3,3,3-trifluoropropene storage tank, wherein the driving cylinder communicates with the pressure reducing valve; the pressure reducing valve communicateswith the drier; the drier is connected with a first valve and a pressure compensation valve; the first valve communicates with the 2-bromo-3,3,3-trifluoropropene storage tank 1; the 2-bromo-3,3,3-trifluoropropene storage tank is connected with a second valve; the flow guiding pipe communicates with the pressure compensation valve and the second valve; and the flow guiding pipe communicates with afinished product bottle which is to be filled with 2-bromo-3,3,3-trifluoropropene. The 2-bromo-3,3,3-trifluoropropene filling device and method have the beneficial effects that the process of dryingand vacuumizing treatment, 2-bromo-3,3,3-trifluoropropene filling and driving gas supplement of the finished product bottle can be finished, air and water in the finished product bottle and a pipelinecan be discharged, and the influence, on a 2-bromo-3,3,3-trifluoropropene fire extinguishing agent, of the air and water is reduced.

Description

technical field [0001] The invention relates to the technical field of fire protection, in particular to a 2-bromo-3,3,3-trifluoropropene filling device and a filling method. Background technique [0002] "Halon" fire extinguishing agent (such as Halon1301, Halon1211) used to occupy a dominant position in the fire extinguishing medium market due to its low toxicity, high fire extinguishing efficiency, and excellent performance such as non-conductivity. However, since the 1980s, scientists studying the environment have gradually discovered that the "halon" fire extinguishing medium has a serious destructive effect on the atmospheric ozone layer, so the United Nations has imposed strict restrictions on its production and use through a series of treaties. As an influential big country, my country has completely eliminated the use of Halon1211 in the civilian field in 2005, and completely eliminated the use of Halon1301 in the civilian field in 2010. Therefore, the development ...
