Aging treatment heat recovery device

Abstract

The invention discloses a novel aging treatment heat energy recycling device. The novel aging treatment heat energy recycling device comprises a heat collecting module, a motor, a pipeline, a heat pump, an electric three-way regulating valve, a manual regulating valve, an environment filter, a temperature difference control module, a flow control module, a temperature control module and a speed control module, wherein the heat collecting module comprises a heat energy recycling module and a heat energy absorption exchange module, the heat energy absorption exchange module comprises a heat energy absorption exchange module B and a heat energy absorption exchange module C, and the heat energy recycling module comprises a heat energy recycling module A and a heat energy recycling module E. The novel aging treatment heat energy recycling device collects and utilizes clean heat energy directly emitted into atmospheric environment when large-power auxiliary equipment specific to BOPP factories normally run, and carries out recycling, combined distribution, circular treatment and utilization as well as intelligent regulation control so as to realize clean, environment-friendly and efficient heat energy recycling and utilization. The requirements of special high-value-added products on production technologies are met, and the energy utilizing efficiency is improved.

Description

technical field [0001] The invention relates to an aging treatment heat recovery device for a high-width, high-velocity biaxially stretched BOPP production line. Background technique [0002] At present, the general technical status of heat energy recovery equipment in the domestic BOPP industry equipment is: the TDO waste heat recovery device newly added through technical transformation, the main heat source of heat energy recovery and utilization is the exhaust gas with a high temperature of 150°C-170°C discharged from the TDO equipment , heat recovery and utilization realized by secondary heat exchange. The existing problems are that the heat conduction efficiency of the heat exchanger is limited by the design structure and installation materials, so that the heat exchange efficiency is not high. After the long-term application and operation test of this technology compared with the old line of our company's plastic industry factory, it is found that the technology of thi...

Problems solved by technology

The existing problems are that the heat conduction efficiency of the heat exchanger is limited by the design structure and installation materials, so that the heat exchange efficiency is not high. After the long-term application and operation test of this technology in the old line of our company's plastic industry factory, we found that the technology of this device is insufficient. There are the following three points: 1. Through the recycling of TDO waste gas, it will have an impact on the workshop environment

2. After long-term use and condensation of waste heat recovery equipment, oil pollution will occur. When the oil pollution reaches a certain amount, it will affect the quality of the products produced in the original workshop

3. The heat exchange efficiency of the device is not high, and the return on investment period is too long
