[0017] In order to make the purpose, technical solutions and advantages of the application clearer, the application will be further described in detail below with reference to the drawings and examples. It should be understood that the specific examples described herein are only used to explain the application and do not limit the application.

[0018] Please refer to Figure 1The embodiment provides a temperature adjusting device for methyl sulfonic acid production, which comprises a heat conduction box 1, heat conduction plates 2, a heat conduction pipe 3 and a temperature adjusting assembly 4, the heat conduction box 1 is used for containing methyl sulfonic acid, the heat conduction plates 2 are used for exchanging heat with the methyl sulfonic acid, the heat conduction pipe 3 is used for changing the temperature of the heat conduction plates 2, and the temperature adjusting assembly 4 is used for adjusting the temperature of heat conduction medium in the heat conduction pipe 3.

[0019] A heat conduction cavity 1a is formed in the heat conduction box 1, a liquid inlet 1b is formed on one side, the methyl sulfonic acid enters the heat conduction cavity 1a through the liquid inlet 1b, and a liquid outlet 1c is formed on the other side, the methyl sulfonic acid is output from the heat conduction cavity 1a through the liquid outlet 1c.

[0020] A plurality of heat conduction plates 2 are arranged in the heat conduction cavity 1a in the horizontal direction, the plurality of heat conduction plates 2 are vertically and fixedly arranged in the heat conduction cavity 1a, and in the two adjacent heat conduction plates 2: the heights of the two heat conduction plates 2 are different, the lower side of one heat conduction plate 2 abuts against the bottom of the heat conduction cavity 1a, the top forms an upper overflow port 1d, and the lower side of the other heat conduction plate 2 is spaced from the bottom of the heat conduction cavity 1a to form a lower overflow port 1e, that is, the methyl sulfonic acid flows between the two heat conduction plates 2, flows out from the upper overflow port 1d of the lower heat conduction plate 2, flows to the upper heat conduction plate 2, then flows out from the lower overflow port 1e of the upper heat conduction plate 2, and then flows to the next lower heat conduction plate 2, so as to make the methyl sulfonic acid flow directionally in the heat conduction cavity 1a, lengthen the flow path and improve the heat conduction effect.

[0021] The heat conduction pipe 3 is filled with heat conduction medium, the heat conduction medium can be water, heat conduction oil and the like, the heat conduction pipe 3 is connected with the plurality of heat conduction plates 2 to transfer heat between the heat conduction pipe 3 and the heat conduction plates 2, and in the embodiment, the heat conduction pipe 3 penetrates through the middle of the heat conduction plates 2, so as to prevent the methyl sulfonic acid from corroding the heat conduction pipe 3 and the heat conduction plates 2, generally, the heat conduction pipe 3 and the heat conduction plates 2 are made of materials with high corrosion resistance to methyl sulfonic acid and high heat conductivity, such as stainless steel.

[0022] The temperature adjusting assembly 4 is communicated with the heat conduction pipe 3 to change the temperature of the heat conduction medium in the heat conduction pipe 3.

[0023] Preferably, the flow direction of the liquid in the heat conduction cavity 1a between the plurality of heat conduction plates 2 is a horizontal first direction, and the flow direction of the heat conduction medium in the heat conduction pipe 3 between the plurality of heat conduction plates 2 is opposite to the first direction. When the temperature of the heat conduction medium is higher than that of the methyl sulfonic acid, the temperature of the methyl sulfonic acid gradually increases in the first direction, and the temperature of the heat conduction medium gradually decreases in the opposite direction. When the temperature of the heat conduction medium is higher than that of the methyl sulfonic acid, the temperature of the methyl sulfonic acid gradually decreases in the first direction, and the temperature of the heat conduction medium gradually increases in the opposite direction. Therefore, the methyl sulfonic acid and the heat conduction medium form a convection, thereby improving the heat conduction efficiency.

[0024] Preferably, the temperature adjusting device for methyl sulfonic acid production further comprises a second temperature sensor 5 arranged at the liquid outlet 1c for detecting the temperature of the liquid in the heat conduction cavity 1a. There is a certain delay in the temperature conduction of the heat conduction medium to the methyl sulfonic acid. The first sensor is used to directly control the operation of the heater 4c and the refrigerator 4d. However, the first sensor cannot directly reflect the temperature of the methyl sulfonic acid. Therefore, the second sensor is needed to directly measure the temperature of the methyl sulfonic acid at the liquid outlet 1c in the heat conduction cavity 1a. When the readings of the first sensor and the second sensor are significantly different, the working power of the heater 4c or the refrigerator 4d is increased, and the temperature change rate is improved. When the temperatures detected by the second temperature sensor 5 and the first temperature sensor 4e are both lower than the predetermined temperature range, the heater 4c is operated to heat the heat conduction medium in the containing box 4a. The liquid pump 4b delivers the heat conduction medium to the heat conduction pipe 3, thereby increasing the temperature of the heat conduction plate 2 and increasing the temperature of the methyl sulfonic acid in the heat conduction cavity 1a. When the temperatures detected by the second temperature sensor 5 and the first temperature sensor 4e are both higher than the predetermined temperature range, the refrigerator 4d is operated to cool the heat conduction medium in the containing box 4a. The liquid pump 4b delivers the heat conduction medium to the heat conduction pipe 3, thereby decreasing the temperature of the heat conduction plate 2 and decreasing the temperature of the methyl sulfonic acid in the heat conduction cavity 1a.

[0025] In summary, the temperature adjusting device for methyl sulfonic acid production provided by the present application is described above. The methyl sulfonic acid enters the heat conduction cavity 1a from the liquid inlet 1b. The flow direction of the methyl sulfonic acid between the two heat conduction plates 2 is from the upper overflow port 1d of the low-side heat conduction plate 2, to the high-side heat conduction plate 2, and then to the next heat conduction plate 2 from the lower overflow port 1e of the high-side heat conduction plate 2. Therefore, the methyl sulfonic acid flows directionally in the heat conduction cavity 1a, and its temperature gradually increases when it contacts each heat conduction plate 2. The flow path of the methyl sulfonic acid is prolonged, and the heat conduction effect is improved.
