Full recovery device of liquid chlorine system

Abstract

The invention discloses a full recovery device of a liquid chlorine system. The full recovery device comprises a working table, a filtering tank, a base and a liquid pumping tank are installed on thetop of the working table, pressure pipes are installed on the two sides of an inner cavity of the liquid pumping tank, an inner cavity of each pressure pipe is provided with a piston block and a pressure spring, a sealing plug is fixedly connected to the top of the liquid pumping tank, and an air pipe is fixedly connected to the middle portion of the top of the inner cavity of the liquid pumping tank; one end of the air pipe is fixedly connected with one side of an air pump, the other side of the air pump is fixedly connected with one end of an air pressure pipe, the other end of the air pressure pipe is fixedly connected with one end of a liquid sucking pipe, and the other end of the liquid sucking pipe is provided with a liquid sucking opening; and a containing table is arranged in an inner cavity of the base, and a liquid chlorine tank is installed at the top of the containing table. According to the full recovery device, the liquid sucking pipe, the air pressure pipe, the air pumpand the air pipe are used in cooperation, and the high pressure principle can be achieved; then residual liquid chlorine in the liquid chlorine tank can be sucked into the liquid pumping tank, and thecondition of liquid chlorine leakage caused when the liquid chlorine tank is replaced can be effectively prevented.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a full recovery device for a liquid chlorine system. Background technique [0002] The chemical name of liquid chlorine is liquid chlorine, which is a yellow-green liquid with a boiling point of -34.6°C and a melting point of -103°C. It is vaporized into a gas under normal pressure. It can be seriously poisoned to the human body if it is inhaled. It has a severe stimulating effect and is corrosive. Combustion and explosion occur when flammable gases are mixed. Chlorine is a very active substance and can react with most elements (or compounds). [0003] At present, when replacing chlorine gas cylinders in the market, it is easy to discharge liquid chlorine. The gas produced by liquid chlorine is not only difficult to remove, but also contains strong corrosiveness in liquid chlorine gas. When this happens, it will not only cause Environmental pollution, but also c...
