Description

Technical Field

[0001] This utility model relates to the field of condensate disposal, and in particular to an energy-saving device for steam condensation heat exchange equipment. Background Technology

[0002] Steam condensing heat exchange equipment is a type of heat exchange device commonly used in industrial fields. Its main function is to condense steam into water through a cooling medium and recover its latent heat, thereby improving energy utilization efficiency. This type of equipment is widely used in industries such as chemical, pharmaceutical, power, and food for heat recovery and management of steam circulation systems. Its basic principle is that steam exchanges heat with cooling water or other cooling media in the condenser, and the temperature of the steam is reduced through heat transfer, eventually transforming into water or other liquid forms.

[0003] Condensers come in various structural forms, including shell-and-tube, plate, and air-cooled types. The specific choice depends on factors such as steam volume, cooling requirements, and installation space. Steam condensing heat exchange equipment can not only effectively reduce energy consumption and production costs, but also improve system operating efficiency. Through reasonable design and optimization of equipment operating parameters, equipment lifespan can be extended, and system stability and safety can be guaranteed. In addition, with increasingly stringent environmental regulations, steam condensing heat exchange equipment can also help enterprises reduce emissions and meet the requirements of energy conservation and emission reduction.

[0004] In chemical production, there are a large number of devices that utilize the latent heat of steam for heating. After the steam condenses, a certain amount of condensate is generated and needs to be sent to a condensate recovery device. Currently, the design uses a steam trap to control the condensate in the heat exchanger to be sent to the condensate recovery device. However, when using a steam trap to recover condensate, it is difficult to control the condensate level in the heat exchanger, and the heat exchange area utilization rate cannot be maximized. The steam trap is also prone to jamming and damage, and steam is discharged while draining water, resulting in steam waste and making it impossible to monitor the process directly and effectively. Therefore, an energy-saving device for steam condensation heat exchange equipment is proposed to solve the above problems. Utility Model Content

[0028] Working Principle: When using this device, the temperature of the distillation column 1 is controlled by the steam regulating valve to control the steam feed flow into the heat exchanger body 3. The steam condenses and releases heat in the heat exchanger body 3, heating and vaporizing the process materials. The condensate from the heat exchanger body 3 enters the condensate tank 6. The connecting port at the top of the condensate tank 6 is connected to the steam port 17 via a three-way valve 16, ensuring that the condensate is discharged smoothly using the level difference. During the initial start-up, exhaust gas and polluted wastewater are discharged through the bottom drain 11 of the condensate tank 6. After sampling and analysis, if no solid impurities are found, the drain 11 is closed. When the liquid level in the condensate tank 6 rises to 30%, the destination of the condensate is determined based on the value of the online conductivity meter 8. If the conductivity is ≥40μ If the conductivity is <40μs / cm, the external discharge regulating valve 10 is opened to send the condensate to the circulating water system. If the conductivity is <40μs / cm, the recovery regulating valve 9 is opened to send the condensate to the condensate recovery device. The interlock between the on-site level gauge 4 and the conductivity detector 8 will, if the conductivity is ≥40μs / cm during operation, close the recovery regulating valve 9 and open the external discharge regulating valve 10 simultaneously to switch the condensate to the circulating water system. Under normal circumstances, the feed regulating valve 12 is opened by the flow meter 13 to discharge steam from the steam port 17. If the gas pressure is too high, the flow meter 13 will immediately open the discharge valve 14, and the steam will be quickly discharged from the discharge valve 14, thereby protecting the entire equipment and ensuring its normal operation. Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
