Description

Technical Field

[0001] This utility model relates to the field of chlorine preparation technology, and in particular to chlorine gasification equipment. Background Technology

[0002] Chlorine is a yellowish-green gas with a pungent odor. It has strong oxidizing properties and can react with many metals and nonmetals. Chlorine reacts with iron to form ferric chloride and with hydrogen to form hydrogen chloride. Chlorine is soluble in water, and its aqueous solution is called chlorine water. Chlorine water has bleaching properties because it reacts with water to form hypochlorous acid, which is a strong oxidizing agent that can decolorize colored substances. Chlorine has a wide range of industrial applications, including the manufacture of bleaching powder, disinfectant, plastics, and pesticides. However, chlorine is toxic, and inhaling excessive amounts can cause serious harm to the human body and even endanger life. Special attention must be paid to safety when using and storing chlorine.

[0003] Liquid chlorine can be converted back into gas under certain conditions. Liquid chlorine is a liquefied form of chlorine with a low boiling point. When liquid chlorine is heated or depressurized, it rapidly absorbs heat and vaporizes, transforming from a liquid to a gaseous state. In industry, liquid chlorine is transported through pipelines, and heating devices are used to control the vaporization rate, converting it into gaseous chlorine. This meets the needs of disinfection and chemical synthesis, enabling the storage, transportation, and flexible application of chlorine and ensuring an effective supply of chlorine in industrial production and daily life. However, if the vaporization temperature is too low, hydrogen trichloride will be produced. Hydrogen trichloride is highly toxic and cannot be released arbitrarily. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a chlorine gasification device, which aims to improve the problem in the prior art where hydrogen trichloride is produced when the temperature is too low during the vaporization of liquid chlorine. Hydrogen trichloride is highly toxic and cannot be discharged at will.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a chlorine gasification device, comprising a feed pipe, one end of which is connected to a dispersion pipe, the outer wall of which is connected to a conveying pipe, the other end of which is connected to a vaporization tank, a spiral tube I and a spiral tube II on the inner wall of the vaporization tank, both ends of the spiral tube I and spiral tube II being connected to a circulation tank, a conveying pump at one end of each spiral tube I and spiral tube II, a gas delivery pipe at the upper end of the vaporization tank, the other end of which is connected to a buffer tank, and an alkalization treatment mechanism at the bottom of the buffer tank for treating hydrogen trichloride.

[0006] As a further description of the above technical solution:

[0007] The alkalization treatment mechanism includes a first connecting pipe, the upper end of which is connected to the bottom of a buffer tank, the bottom of which is connected to a reaction tank, a second connecting pipe connected to the middle of the reaction tank, an alkali storage tank at the other end of the second connecting pipe, an automatic valve on the second connecting pipe, a motor fixedly connected to the bottom of the reaction tank, and a stirring rod fixedly connected to the output end of the motor through the bottom of the reaction tank.

[0008] As a further description of the above technical solution:

[0009] An inlet shut-off valve is provided at one end of the conveying pipe, and a regulating valve is provided in the middle of the conveying pipe.

[0010] As a further description of the above technical solution:

[0011] The vaporization tank is provided with a cover plate at the top, and multiple locking buckles are fixedly connected to the top of the cover plate, with a locking rod provided in the middle of the locking buckle.

[0012] As a further description of the above technical solution:

[0013] The inner wall of the circulation tank is fixedly connected with multiple heating plates, and a liquid level indicator is provided in the middle of the vaporization tank.

[0014] As a further description of the above technical solution:

[0015] A valve is provided at one end of the conveying pipe, and multiple dispersers are provided on the top of the cover plate.

[0016] As a further description of the above technical solution:

[0017] The bottom surface of the buffer tank is fixedly connected with multiple support legs, and the outer wall of the buffer tank is provided with a discharge port.

[0018] As a further description of the above technical solution:

[0019] The bottom of the reaction vessel is provided with a waste outlet, and the outer wall of the reaction vessel is provided with an acid-base indicator.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, liquid chlorine gas is input through the feed pipe and dispersed into multiple conveying pipes through the dispersion pipe. The conveying pipes transport the liquid chlorine gas to the vaporization tank. The water in the circulation tank is heated to 70 degrees Celsius by the heating plate. The spiral tubes one and two are arranged in opposite directions to ensure that the temperature in the vaporization tank is uniform and stable, resulting in higher vaporization efficiency and preventing the generation of a large amount of hydrogen trichloride due to excessively low temperature. The vaporized chlorine gas is transported to the buffer tank through the gas delivery pipe and then transported out from the buffer tank for use.

[0022] 2. In this invention, vaporized chlorine gas is stored in a buffer tank. Due to its higher density, hydrogen trichloride is deposited in the buffer tank and enters the reaction tank through a connecting pipe. An acid-base indicator monitors the acidity and alkalinity in the reaction tank. An automatic valve controls the alkaline solution in the alkaline storage tank to enter the reaction tank and react with the hydrogen trichloride. A stirring rod is installed in the reaction tank, and a motor drives the stirring rod to rotate, so that the hydrogen trichloride and alkaline solution are fully mixed, accelerating the neutralization reaction. The waste outlet is used to discharge the neutralized product from the reaction tank. Attached Figure Description
