Abstract
Description
Technical Field
[0001] This utility model belongs to the field of steam generator technology, specifically relating to a new type of energy-saving pure steam generator. Background Technology
[0002] Pure steam generators are widely used in sterilization and disinfection of medical and health, biopharmaceutical, and food industries, as well as the disinfection of related equipment, effectively preventing recontamination by heavy metals and other impurities.
[0003] In existing technologies, pure steam generators often suffer from low heat exchange efficiency and high steam consumption, leaving considerable room for improvement. Utility Model Content
[0004] To overcome the above-mentioned technical problems, this utility model provides a novel energy-saving pure steam generator.
[0005] The present invention adopts the following technical solution:
[0006] A novel energy-saving pure steam generator includes an evaporator. The shell side of the evaporator has an industrial raw steam inlet. The steam outlet of the evaporator is connected to the steam inlet of the shell side of a heater. The steam outlet of the heater is connected to the steam inlet of the shell side of a preheater. The other end of the shell side of the preheater has a condensate outlet. The tube side of the preheater has a raw water inlet. The water outlet at the other end of the preheater is connected to the water inlet of the tube side of the heater. The water outlet at the other end of the heater is connected to the water inlet of the tube side of the evaporator. The steam outlet of the evaporator is connected to the inlet of a separator. The separator also has a liquid outlet and a steam outlet.
[0007] Preferably, the drain outlet of the separator and the outlet of the evaporator converge.
[0008] Preferably, a steam trap is installed in the pipeline between the steam outlet of the heater and the steam inlet of the preheater.
[0009] Compared with the prior art, the beneficial effects of this utility model are:
[0010] 1. This utility model utilizes the high-temperature steam condensate from the heater to further heat the raw water, and then uses industrial live steam to evaporate the raw water effectively, improving the evaporation effect, reducing steam condensate discharge, and lowering steam consumption. The heat of the steam condensate is transferred to the raw water through the preheater, which can also cool the steam condensate. After cooling, the condensate is discharged outside the machine. At the same time, the raw water is also preheated during the cooling process of the steam condensate. This achieves both steam condensate cooling and raw water preheating. The structure is simple, the construction and operation and maintenance costs are low, and the industrial live steam consumption is low.
[0011] 2. The secondary steam generated by the evaporator is separated into vapor and liquid by the separator to obtain pure steam, which is then discharged from the exhaust port. Under the action of centrifugal force of high-speed rotation in the separator, its separation factor can reach hundreds of times the acceleration of gravity. Tiny water droplets and mist in the secondary steam are centrifugally separated along the spiral tangential direction and thrown towards the isolation cylinder wall. Then, they are collected downward along the cylinder wall and discharged from the bottom drain port of the separator, achieving a significant and ideal separation effect and obtaining pure steam.

Throughout the drawings, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions. Unless otherwise specified, the raw materials and equipment used are commercially available or commonly used in the art.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0018] A novel energy-saving pure steam generator includes an evaporator. The shell side of the evaporator has an industrial raw steam inlet. The steam outlet of the evaporator is connected to the steam inlet of the heater shell side. The steam outlet of the heater is connected to the steam inlet of the preheater shell side. A steam trap is installed in this section of the pipeline to ensure that the upstream steam provides sufficient and uniform heating. The other end of the shell side of the preheater has a condensate outlet. The tube side of the preheater has a raw water inlet. The water outlet at the other end of the preheater is connected to the water inlet of the heater tube side. The water outlet at the other end of the heater is connected to the water inlet of the evaporator tube side. The steam outlet of the evaporator is connected to the inlet of a separator. The separator also has a liquid outlet and a steam outlet. The liquid outlet of the separator and the liquid outlet of the evaporator converge to drain water.
[0019] A new type of energy-saving pure steam generator, when in use:
[0020] Please see Figure 1 (Green pipeline) Figure 2 Steam route: Industrial raw steam enters the shell side of the evaporator from the industrial raw steam inlet, where it exchanges heat with the raw water in the tube side. The condensate generated after the heat exchange enters the shell side of the heater to heat the raw water. After heat exchange, it enters the shell side of the preheater and is cooled by heat exchange with the raw water before being discharged from the condensate outlet.
[0021] Please see Figure 1 (Blue and red pipes) Figure 3 Raw water route: Raw water enters the tube side of the preheater from the raw water inlet. After being preheated by the steam condensate, it enters the tube side of the heater and is further preheated by the steam-water mixture in the shell side. Then it enters the evaporator, where it exchanges heat with the industrial live steam in the shell side. The generated secondary steam enters the separator and is finally discharged as pure steam from the exhaust port through the spiral plate steam-liquid separation channel. Unevaporated raw water in the evaporator is discharged from the liquid outlet, and the condensate separated by the separator is discharged from the liquid outlet. The two waters merge and are discharged outside the machine.
