Description

Technical Field

[0001] This utility model relates to the field of desulfurization process technology, and more specifically, to a rich liquid heater. Background Technology

[0002] A rich liquid heater is a device used to heat liquids, mainly in industrial production, especially in chemical and fertilizer production processes. Rich liquid heaters are typically used to heat rich liquids to meet the temperature requirements of the production process. The working principle of a rich liquid heater is mainly to collect the waste heat generated in industrial production and use this heat to heat the liquid.

[0003] The desulfurization process usually generates heat, and the desulfurization reaction is usually an exothermic process, which means that heat is released during the reaction. The heat generated by the desulfurization in the current technology is not easy to utilize, resulting in a certain amount of waste. At the same time, after the rich liquid is in the rich liquid heater, due to the presence of certain solid particles inside, they will be adsorbed on the serpentine tube in the rich liquid heater for a long time, which will greatly reduce the heat exchange efficiency.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to propose a liquid-rich heater.

Both the temperature sensor and the water level sensor are electrically connected to an external controller.

[0008] Preferably, the serpentine waste heat utilization assembly includes a serpentine heat exchange pipe located inside the rich liquid heating tank, with one end of the inlet pipe and one end of the outlet pipe fixedly connected to the end of the serpentine heat exchange pipe.

[0011] Preferably, the bottom of the inner cylinder is fixedly connected to a lower filter screen via a central shaft, and the bottom of the upper cylinder is integrally connected to the lower cylinder, with the lower filter screen located inside the lower cylinder.
