Description

Technical Field

[0001] The utility model relates to the technical field of liquid chlorine gasifiers, in particular to a liquid chlorine gasifier for chemical production. Background Art

[0002] To facilitate gas storage, transportation and improve safety, people convert gas from gas to liquid by compressing the volume and lowering the temperature. Chlorine is an important basic chemical raw material used to produce plastics, pesticides, medicines, etc. It can also be used for disinfection and bleaching. It is stored and transported in liquid form. Liquid chlorine needs to be converted into chlorine gas by gasification before use. The conversion of liquid chlorine into chlorine gas is a physical process that absorbs heat and increases in volume. At the same time, chlorine is highly toxic and is a hazardous chemical, so chlorine-related processes and equipment must consider safety factors more.

[0003] The existing liquid chlorine gasifier has the following main drawbacks during use: the heat exchange area is small, and the temperature cannot be guaranteed to be stable, resulting in low gasification efficiency. In addition, due to the low temperature of liquid chlorine, the gasifier shell is prone to brittle changes, resulting in cracks and other damage, thereby causing liquid chlorine leakage. Therefore, there is room for improvement. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0022] Some embodiments of the present invention are described below in conjunction with the accompanying drawings.

[0023] Embodiment 1:

[0024] Combination Figure 1-3 As shown, this embodiment provides a liquid chlorine gasifier for chemical production, including: a main body module 100.

[0025] Among them, the main module 100 includes a cylinder 110, a liquid inlet pipe 120 installed on one side of the cylinder 110 and connected to the inner cavity of the cylinder 110, an exhaust pipe 130 installed on one side of the cylinder 110 and connected to the inner cavity of the cylinder 110, a bottom shell 140 fixed at the bottom end of the cylinder 110, a top shell 150 fixed at the top end of the cylinder 110, heat exchange tubes 160 installed in a circular array in the inner cavity of the cylinder 110 and extending at both ends of the cylinder 110 and connected to the bottom shell 140 and the top shell 150 respectively, a box 170 fixed to one side of the cylinder 110 by a bracket, a pump 180 installed at the bottom end of the box 170, and a temperature control component 190 installed on the box 170 and extending into the inner cavity of the box 170.

[0026] The cylinder 110 is used to provide a space for gasification of liquid chlorine and is sealed to prevent leakage of gasified chlorine. The cylinder 110 consists of an outer shell 111, a middle shell 112 fixed to the inner side of the outer shell 111, and an inner shell 113 fixed to the inner side of the middle shell 112. The three-layer shell setting can effectively prevent the problem of liquid chlorine becoming brittle and broken due to low temperature, resulting in leakage.

[0027] The liquid inlet pipe 120 is used to introduce liquid chlorine into the inner cavity of the cylinder 110, and the exhaust pipe 130 is used to discharge the vaporized liquid chlorine.

[0028] The heat exchange tube 160 is used for warm water to pass through. When the warm water passes through the heat exchange tube 160, the liquid chlorine can exchange heat with the warm water through the heat exchange tube 160, absorb heat, and then vaporize. The top end of the heat exchange tube 160 is connected with the top shell 150, so that the cooled water can be sent into the top shell 150. The bottom end of the heat exchange tube 160 is connected with the bottom shell 140, so that the warm water can enter the heat exchange tube 160. In addition, a plurality of annular plates 161 are fixed in an array on the surface of the heat exchange tube 160, so as to further increase the contact area between the liquid chlorine and the heat exchange tube 160 and improve the vaporization efficiency.

[0029] The box body 170 is used to be fixed on one side of the cylinder body 110 by a bracket and is used to store water. The top shell 150 is connected to the inner cavity of the box body 170 through a connecting pipe 171, so that the water after heat exchange can return to the inner cavity of the box body 170. The inlet of the pump 180 is connected to the inner cavity of the box body 170, and the outlet of the pump 180 is connected to the bottom shell 140 through a delivery pipe 181, which is used to pump the heated water in the box body 170 into the bottom shell 140, so that it enters the heat exchange tube 160 through the bottom shell 140 to form a circulation.

[0030] In addition, the box body 170 is made of heat-insulating material, which can effectively reduce unnecessary heat energy loss when heating water in the box body 170.

[0031] The temperature control assembly 190 includes an electric heating tube 191 fixed on the outside of the box 170 and extending into the inner cavity of the box 170, and a temperature sensor 192 installed on the top of the box 170 and extending into the inner cavity of the box 170. The electric heating tube 191 is used to heat the water in the inner cavity of the box 170, and the temperature sensor 192 is used to detect the water temperature and turn off the electric heating tube 191 when the water temperature reaches the set value.

[0032] The working principle and use process of the utility model are as follows: when in use, liquid chlorine is delivered to the inner cavity of the cylinder 110 through the liquid inlet pipe 120. At this time, the electric heating pipe 191 is started to heat the water in the box 170. At the same time, the temperature sensor 192 monitors the temperature of the water in the box 170 in real time. When the water temperature in the box 170 reaches the set value, the pump 180 is started to pump the water pump in the box 170 into the bottom shell 140 through the delivery pipe 181. The warm water enters the heat exchange tube 160 evenly through the bottom shell 140. At this time, the liquid chlorine and the warm water in the heat exchange tube 160 are heat exchanged through the heat exchange tube 160. The liquid chlorine absorbs heat and vaporizes, and the temperature of the warm water is reduced. The vaporized liquid chlorine is delivered through the exhaust pipe 130, and the cooled water enters the top shell 150 and returns to the box 170 through the connecting pipe 171. Then the above process is repeated to realize the vaporization of the liquid chlorine.

[0033] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
