Technical Field
[0001] This utility model relates to the field of amine-rich liquid heat exchanger technology, specifically to a novel amine-rich liquid heat exchanger device. Background Technology
[0002] Traditional amine-rich liquid heat exchangers typically utilize the temperature difference between high-temperature rich amine liquid and low-temperature lean amine liquid to achieve energy conversion and utilization through heat transfer. They are primarily used to recover heat from waste gas or waste liquid and convert it into usable energy, thereby improving energy efficiency.
[0003] However, this would require collecting other heat sources for heat exchange. In view of this, we propose a novel amine-rich liquid heat exchanger device, which mainly uses high-temperature amine-rich liquid as a heat source for heat exchange, thereby achieving the heating treatment of low-temperature amine-rich liquid.

[0006] Furthermore, the plate heat exchanger includes heat exchange plates, one side of which abuts against the container holding the low-temperature lean-rich amine liquid, and the other side of which abuts against the surface of the plate heat exchanger. In practical applications, this design facilitates the heating and temperature rise of the low-temperature lean-rich amine liquid.
[0007] Furthermore, the outlet pipe is equipped with a connecting sleeve, and the heat exchange assembly pipe also includes a mounting flange. The main installation pipe is detachably connected to the connecting sleeve via the mounting flange. In practical applications, this design facilitates installation.
[0008] Furthermore, the heat exchange assembly also includes a liquid inlet pump, which is installed at the liquid inlet pipe and located between the high-temperature lean-rich amine liquid and the plate heat exchanger. In practical applications, this design facilitates the liquid inlet pump to transfer the high-temperature lean-rich amine liquid.
[0009] Furthermore, the heat exchange assembly also includes a liquid outlet pump, which is installed at the liquid outlet pipe. In practical applications, this design effectively facilitates liquid pumping.
[0010] As can be seen from the above technical solution, the beneficial effects of the novel amine-rich liquid heat exchanger device provided by this utility model are as follows:
[0011] (1) In practical applications, the heat of the high-temperature lean amine liquid is transferred to the low-temperature lean amine liquid through the plate heat exchanger, which effectively reduces the reliance on other heat sources and thus reduces the overall cost of use.
