Abstract

The invention discloses a waste heat recycling system which comprises a preheating barrel, a condensation crystallization barrel, a steam-water separator and an induced draft fan. The inner wall of the preheating barrel is provided with a coil pipe, and the two ends of the coil pipe extend out of the preheating barrel. The condensation crystallization barrel is connected with the preheating barrel and used for receiving raw material liquid in the preheating barrel; one end of the steam-water separator is connected with the upper portion of the condensation crystallization barrel through a pipe, the steam-water separator collects steam evaporated out of the condensation crystallization barrel and recycles condensed water in the steam, and the other end of the steam-water separator is connected with a coil pipe air inlet of the preheating barrel through a pipe and used for leading the steam into the coil pipe. The induced draft fan is connected with an air outlet of the coil pipe. The coil pipe is arranged on the inner wall of the preheating barrel, the steam can perform heat exchange with cold raw material liquid in the preheating barrel fully in process of passing in the coil pipe, and the steam heat usage rate is improved.

Description

technical field [0001] The invention relates to the field of heat utilization. More specifically, the present invention relates to a waste heat recovery system. Background technique [0002] In the process of concentrating crystallization raw material liquid in chemical plants, it is necessary to heat and evaporate the raw material liquid to carry out concentrated crystallization. The existing concentration and crystallization process allows the evaporated steam to be discharged directly, which not only causes a lot of energy waste, but also makes the temperature of the concentrated crystallization factory area higher, which leads to higher production costs for enterprises and cannot respond to the national call for energy conservation and emission reduction. , which is detrimental to the long-term development of the enterprise. Therefore, it is necessary to develop a system for recovering the exhausted heat to reduce the production cost of the enterprise and respond to th...
