The description of these embodiments is provided to assist understanding of the present utility model, but is not intended to limit the present utility model. In addition, technical features of the embodiments of the present utility model described below may be combined with each other as long as they do not collide with each other.
Fig. 1 is a schematic flow chart of a circuit board heat recovery system according to the present utility model. The circuit board heat recovery system comprises a waste heat supply unit 1, a first heat exchange unit 2, a second heat exchange unit 3 and an air compressor heat recovery unit 4. The heat return water of the waste heat supply unit 1 is from heat utilization equipment, and can be concentrated and stored in a buffer tank, wherein the temperature of the heat return water is 50-58 ℃, and the heat return water is used for heat recovery of the air compressor after passing through the first heat exchange unit 2 and the second heat exchange unit 3.
The first heat exchange unit 2 uses tap water as cooling water to cool the hot backwater provided by the waste heat providing unit, and the cooling water is heated for the life of factory workers. Specifically, the cooling water inlet end of the first heat exchange unit 2 is connected with a tap water pipe, and the water outlet end is connected with a domestic hot water tank. The tap water pipe connected with the first heat exchange unit 2 is a PPR75 pipe, the water temperature of the water outlet end of the cooling water is 42-50 ℃, and the tap water pipe can be used for workers in a factory living area. In practical application, the water in the domestic hot water tank needs to be heated, and when the water reaches the set value, the heating of the hot water in the domestic hot water tank is stopped. Because of the introduction of an external heat source, the energy consumption generated by heating the hot water in the domestic hot water tank can be saved. In order to further save energy consumption, a pipeline between the cooling water outlet end of the first heat exchange unit and the domestic hot water tank is designed to be a heat preservation pipe, so that heat dissipation is prevented.
The second heat exchange unit 3 is used for carrying out heat exchange cooling on the hot backwater subjected to heat exchange by the first heat exchange unit 2 again, so that the temperature of the hot backwater is reduced to be below 35 ℃ so as to be convenient for the air compressor. In the utility model, the second heat exchange unit 3 is formed by connecting two heat exchange units in series, and the cooling water of the two heat exchange units is provided by a cooling water tower. As the cooling treatment of the first heat exchange unit is carried out in the early stage, the temperature of the hot backwater entering the second heat exchange unit 3 is reduced, and compared with the scheme that the hot backwater of the waste heat providing unit is totally cooled by the cooling water tower in the prior art, the energy consumption of the operation of the cooling water tower can be reduced.
And the hot backwater after heat exchange and cooling by the second heat exchange unit 3 is conveyed to the air compressor heat recovery unit 4, and the air compressor is subjected to 1-level, 2-level and 3-level heat recovery heat exchange and air compressor gas cooling. The temperature of the backwater after heat exchange by the air compressor heat recovery unit 4 is raised to about 60 ℃, and the backwater can be used by workshop heat equipment, so that the backwater can be recycled.
In the present utility model, the heat exchangers used in the first heat exchange unit 2 and the second heat exchange unit 3 are plate heat exchangers.
The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings, but the present utility model is not limited to the described embodiments.
