Description

High-temperature steam condensate water recovery device Technical Field The utility model belongs to the technical field of condensate water recovery, and particularly relates to a high-temperature steam condensate water recovery device. Background High temperature steam condensate refers to water formed by condensing steam after releasing latent heat, and the temperature of the water is close to the saturation temperature of the steam. In industrial applications, steam condensate typically has a relatively high temperature. The prior Chinese patent with the publication number of CN219015028U discloses a high-temperature steam condensate recovery device which comprises a steam condensate discharge pipe, a circulating water tank and a circulating pump which are connected through a pipeline, and circulating water arranged in the circulating water tank, and is characterized in that the lower section of a recovery cylinder is arranged in the circulating water, the tail end of the steam condensate discharge pipe penetrates through the recovery cylinder and is arranged below the liquid level of the circulating water in the recovery cylinder, an outlet of the circulating pump is connected with a spray head through a circulating pipe, and the spray head is arranged in the recovery cylinder above the liquid level of the circulating water. When the steam condensate is used, the steam condensate is led into the circulating water liquid level in the recovery cylinder through the steam condensate discharge pipe, the liquid seal formed by the insertion depth of the steam condensate discharge pipe is utilized, the outlet pressure of the condensate is increased, so that the phenomenon that flash evaporation occurs due to the reduction of the outlet pressure and secondary steam is generated is avoided, the low-temperature circulating water in the circulating water tank exchanges heat with the high-temperature condensate, a large amount of circulating water takes away the heat of the condensate, and meanwhile, the spray head sprays in the recovery cylinder, so that the pollution of the field environment caused by the overflow of a small amount of steam is prevented. In view of the above-mentioned related art, the inventors have found that there is at least a problem in that the high-temperature steam condensate is not completely pure, the high-temperature steam condensate may carry impurities in a boiler or a pipeline, if the high-temperature steam condensate with impurities is directly discharged into the circulation tank, the high-temperature steam condensate directly contacts with water in the circulation tank, and then the water in the circulation tank is polluted, so that the water quality in the circulation tank is reduced, and even if the heat of the high-temperature steam condensate is absorbed by the circulation water, the utility value of the circulation water is reduced.
