In the paper industry, the water consumption in the pulping process is extremely high, so water saving has always been one of the urgent problems in the paper industry. 
Water saving in the paper industry can not only reduce the consumption of clean water, but also reduce the discharge of wastewater. 
At the same time, it can also bring benefits of energy saving and consumption reduction. 
The plate heat exchanger improves the heat exchange efficiency in the heating and cooling stages of the production process. The final result is that it saves raw materials, improves energy efficiency and reduces waste water discharge. This is achieved with three birds with one stone, thanks to the plate heat exchanger 
This feature of high heat exchange efficiency.

The plate heat exchanger of the paper mill plays a major role in two production links, one is waste heat recovery and the other is wastewater treatment (workshop process wastewater, production wastewater, thermal power station wastewater, cooling water discharge, etc.). 
A large amount of high-temperature waste liquid will be produced in the cooking system of papermaking: in the process of high-temperature recycling and waste liquid treatment and secondary utilization, the high heat exchange efficiency of the plate heat exchanger comes in handy. 
Through the plate heat exchanger, the heat of the waste water is transferred to the tap water, and the heated tap water is used for the production of hot water or for the workers to take a bath. 
The treatment of waste liquid extracts the elements that were first fully utilized for secondary use. 
Qingdao RPT’s engineer team has been adhering to the principles of high efficiency, environmental protection, and energy saving, and has implemented the company values of "Honesty and Dedication". With nearly 20 years of industry experience, it has focused on the research and development of plate heat exchanger waste heat recovery and heat exchange equipment. 
Promote the development of environmental protection.
