Embodiment 1

[0039] like figure 1 As shown, on the one hand, the embodiments of the present invention provide an air compressor waste heat recovery and utilization waste heat

[0040] A system for heating etching potion, including an oil-water heat exchanger and an insulated water tank, the hot oil inlet of the oil-water heat exchanger communicates with the hot oil outlet of the air compressor, and the cold oil return outlet of the oil-water heat exchanger It is connected with the cold oil inlet of the air compressor; the air compressor is a screw air compressor.

[0041] The hot water outlet of the oil-water heat exchanger communicates with the hot water inlet of the thermal insulation water tank, the cold return water outlet of the thermal insulation water tank communicates with the cold water inlet of the oil-water heat exchanger, and connects to There is a first circulating water pump 1; the communication pipes between each device can adopt thermal insulation pipes.

[0042] The hot ...

Embodiment 2

[0056] like figure 2 As shown, the difference from Example 1 is that a replenishment water tank is connected to the heat preservation water tank, and when the water in the heat preservation water tank is insufficient, the heat preservation water tank is replenished, and a check valve is also arranged on the water outlet pipeline of the water replenishment tank.

Embodiment 3

[0058] like image 3 As shown, the difference from Embodiment 2 is that a water filter is added at the water inlet of the replenishment tank.

[0059] In the embodiment of the present invention, the waste heat of the air compressor is stored in the form of hot water at 70-80°C to obtain free heat energy at a temperature between 70-80°C, and this part of the heat energy stored in the form of hot water, Through the insulation pipeline, it is transported to the potion tank of the PCB etching line, browning line, copper sinking line, developing line, etc. that need to be heated, or other hardware surface treatment processes, or other product surface treatment processes. Through the water and the water heat exchanger, the chemical medicine or solution in the above process, or the water used for cleaning is exchanged for heat.

[0060] For example, the electric heating pipe (or steam heating produced by diesel, gas, and coal combustion) equipped with a standard PCB sinking copper w...

Abstract

The invention relates to the technical field of recycling of waste heat, in particular to a system for recycling waste heat of an air compressor and heating etching chemical liquid by using waste heat. The system comprises the air compressor, an oil-water heat exchanger, a heat-insulation water tank, a circulating water pump, an electromagnetic valve, a temperature control device and the like. Various chemical liquid grooves in a production procedure of a circuit board can be heated through waste heat of the air compressor, so that the production cost is saved. Moreover, the temperature of recycled hot water ranges from 70 DEG C to 80 DEG C, and chemical liquid of a circuit board production line can be protected.

Description

technical field [0001] The invention relates to the technical field of waste heat recovery and reuse, in particular to a system and method for recovering waste heat from an air compressor and heating etching liquid by using the waste heat. Background technique [0002] At present, most of the potions and various solutions in various surface treatment processes such as etching lines, browning lines, immersion copper lines, and electroplating lines in the PCB board production process need to be heated. The heating temperature is generally 30-80°C. Electric heating rod way to heat. [0003] Above-mentioned conventional heating method has following shortcoming: [0004] 1. First of all, the cost is high. Electric heating, a standard immersion copper wire for heating electricity costs about 1 million yuan a year. [0005] 2. Not environmentally friendly. Although electric heating does not directly produce carbon dioxide, a large amount of carbon dioxide is also produced when ...
