Description

Technical Field

[0001] The present application relates to the technical field of gas delivery equipment, and in particular to a gas delivery thermal compensation heating block. Background Art

[0002] Gas delivery equipment is widely used in industrial production, especially in the chemical, pharmaceutical, food processing and other industries. Gas delivery equipment mainly includes air pipes and control and detection equipment and other additional equipment installed on the air pipes. The control and detection equipment mainly includes control valves, safety valves, pressure gauges, flow meters and online analyzers, etc. Other additional equipment includes filters and pressure reducing devices, etc. The control and detection equipment and other additional equipment are mainly used for safety monitoring, production monitoring, gas delivery and gas pretreatment, etc. These control and detection equipment and other additional equipment are mainly concentrated in the gas inlet chamber. After the gas passes through the boosting equipment (such as blowers, compressors, pumps and boilers), the gas flows from the high pressure in the air pipe to the low pressure. It can also be transported by the gas's own pressure or gravity.

[0003] When designing and operating gas delivery equipment, it is very important to ensure that the temperature of the gas is stable, because temperature fluctuations will affect production efficiency and product quality. When the gas flow in the air pipe is controlled by a control valve or when the ambient temperature changes, the temperature of the gas in the air pipe will change, which will affect the delivery of the gas. In particular, when the pressure of the air flow in the air pipe is reduced by a pressure regulating valve, the Joule-Thomson effect will occur, causing the temperature in the air pipe to drop, and even causing condensation and frost inside the air pipe, which can easily affect the normal flow of gas and the service life of the air pipe. Summary of the invention The present application provides a gas transport thermal compensation heating block, the purpose of which is to perform thermal compensation on the fluid inside the air pipe so that the temperature of the fluid inside the air pipe can return to normal when it decreases, thereby reducing the temperature fluctuation of the fluid, ensuring the normal circulation of the gas and the service life of the air pipe.

[0063] After the outer fixing plate 13 is installed, the electromagnetic plate 182 is energized, and the electromagnetic plate 182 attracts the permanent magnetic plate 181. At this time, the auxiliary fixing plate 16 moves toward the direction of the corresponding outer fixing plate 13. At this time, the auxiliary fixing plate 16 and the corresponding outer fixing plate 13 can automatically clamp the corresponding heating tube group 21. This facilitates the automatic positioning of the auxiliary fixing plate 16.
