specific Embodiment 1
[0022] Such as figure 1 The lower end of the heating layer of the primary heating chamber 10 is connected to the first steam trap 13, the upper left side of the primary heating chamber 10 is provided with a steam inlet 14, and steam enters the heating layer of the primary heating chamber 10 from the steam inlet 14 to provide heat for it The primary heating chamber 10 heats the material liquid to be evaporated, and the steam condensed water formed in the primary heating chamber 10 is regularly discharged through the first steam trap 13 to ensure that the steam in the primary heating chamber 10 is saturated dry steam. The upper end of the primary heating chamber 10 is provided with a steam pressure gauge and a safety valve 11 to ensure heating within a preset pressure value and ensure production safety. The lower ends of the primary heating chamber 10 and the secondary heating chamber 30 are respectively provided with a first cleaning wastewater pipeline 12 and a second cleaning...
specific Embodiment 2
[0027] Such as figure 2 Compared with the specific embodiment 1, a condensate sensible heat recovery device is added. The condensate sensible heat recovery device includes a heat exchanger 80 and a high-temperature condensate recovery tank 70. The heat exchanger 80 is connected to the inlet of the primary heating chamber 10. On the feed liquid pipeline, the first steam trap 13, the second steam trap 51 and the third steam trap 61 are respectively connected to the water inlet of the high-temperature condensate recovery tank 70 through pipelines, and discharge the high-temperature steam condensate to the high-temperature condensate recovery tank 70.
[0028] The water outlet of the high-temperature condensate recovery tank 70 is connected to the heat exchanger 80, and the heat exchanger 80 is provided with a heating layer and a heat-receiving layer, and a delivery pump 71 is provided between the high-temperature condensate recovery tank 70 and the heat exchanger 80. The high-t...
