Embodiment Construction
[0010] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0011] See attached figure 1 , the present invention includes that it comprises the liquid chlorine shunt filter 9 installed between the tank car valve 8 of the liquid chlorine tank car 6 and the crane pipe valve 7 of the unloading crane pipe 4, a belt normally closed valve connected with the liquid chlorine shunt filter 9 The gas pipeline 2 of the valve 3 and the air purification dryer 1 arranged at the other end of the gas pipeline 2 .
[0012] See attached figure 2 , the body shape of the liquid chlorine shunt filter 9 is cylindrical, and an upper baffle 9-2 and a lower baffle 9-3 are arranged at a certain distance inside, and a filter layer 9-3 is filled between the upper and lower baffles. 6. The filter layer 9-6 is made of silicic acid cotton. The lower part of the lower baffle 9-3 forms an air storage chamber 9-8, and the up...

The invention discloses a purification recovery device capable of preventing liquid chlorine leakage. The purification recovery device comprises 1, a liquid chlorine partial flow filter between a tank car valve and an unloading arm valve, 2, a gas pipe of which one end is connected to the liquid chlorine partial flow filter, and 3, an air purification dryer arranged at the other end of the gas pipe. The liquid chlorine partial flow filter has a cylindrical main body. An upper baffle plate and a lower baffle plate are arranged in the cylindrical main body. A filtration layer is arranged between the upper baffle plate and the lower baffle plate. A lower part of the lower baffle plate forms a gas storage chamber. The gas storage chamber is connected to the gas pipe by a first flange at the side. An upper part of the liquid chlorine partial flow filter is connected to the unloading arm valve by a second flange and a lower part of the liquid chlorine partial flow filter is connected to the tank car valve by a third flange. The liquid chlorine partial flow filter can purify liquid chlorine. Through high pressure air in the compressed air purification dryer, residual liquid chlorine in an unloading arm and between the tank car valve and the unloading arm valve is recovered in a liquid chlorine storage tank, and thus the purification recovery device solves the problem that residual liquid chlorine in the unloading arm after unloading of a liquid chlorine tank car is released into the air, and thus air pollution is avoided.
Description
technical field [0001] The invention relates to a liquid chlorine recovery device, in particular to a purification recovery device used on a liquid chlorine tank car to prevent liquid chlorine leakage. Background technique [0002] At present, after the unloading of the liquid chlorine tank truck in the chlor-alkali enterprise, the crane pipe used for unloading is separated from the tank truck. After the valve of the crane pipe and the tank truck valve are closed, the trace liquid chlorine residue between the two valves will leak, causing pollution, and Waste is generated. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a purification and recovery device that can prevent leakage of liquid chlorine and improve the quality of liquid chlorine. [0004] In order to solve the above problems, the technical solution adopted by the present invention is: a purification and recovery device for preventing leakage of liquid...
