[0002] In industrial production, industrial boilers are installed as long as the production process requires steam. Many industries use steam equipment. To maintain the temperature of process steam, a part of the cooled steam and high-temperature condensate must be discharged. About 30% of the heat energy in the discharged steam and high-temperature condensate can be recovered into the boiler for heat recovery, achieving the purpose of recycling and saving energy.

[0003] During the steam recovery process, the steam recovery machine needs to be supplied with cooling water, and at this time it is usually necessary to install it in a supply device. The supply device in the prior art is mostly composed of a water pump and a pipeline. The water pump is placed in a water source, extracts water from the water source and transports the water to the steam recovery machine to achieve the effect of cooling the steam. However, the disadvantages of the prior art are that the cooling water for the steam is directly supplied from the water source, which is prone to impurities, and after contacting with the steam recovery, it is easy to reduce the subsequent condensation effect of the steam. Secondly, impurities in the water quality are also easy to corrode the pipeline, and the pipeline in the prior art is connected by flanges, which is inconvenient to connect. For this reason, we design a cooling water supply device for steam recovery. Summary of the invention
