Device adopts condensed water circuit controls scheme, the small diameter electric control valve is installed between heat exchanger condensation-water drain and condensation water tank, control by the steam condensate (SC) liquid level in this valve heat exchanger, in heat exchanger, the height of condensed water liquid level has determined to enter the size of heat exchanger steam flow, thereby the surface area of a high-temperature water contact steam in vapour-water-to-water heat exchanger is changed, the condensed water liquid level is lower, the flow that steam enters heat exchanger is larger, the area that current contact with steam will be larger, and one time the high-temperature water temperature is higher; When the condensed water liquid level is higher, the flow that steam enters heat exchanger is less, and the area that current contact with steam is less, and one time the high-temperature water temperature is lower, thereby reaches the temperature of controlling a high-temperature water by controlling the steam condensate (SC) water level.
Control the condensed water liquid level of vapour-water-to-water heat exchanger by this device, along with constantly entering of steam flow, thereby can form water after steam-condensation causes condensate water level to change, when a high-temperature water temperature is controlled in setting range, unnecessary steam condensate (SC) will be expelled in condensation water tank by the small diameter electric control valve, condensate temperature in condensation water tank will be higher than the return water temperature of a pipe network at this moment, after pressure of return water is lower than desired value, condensed water will directly fill in return pipe net by small pump, directly improve return water temperature, and reduced the consumption of steam.
This device can be controlled at the liquid level in heat exchanger lower bound 10%; in high limit 90% scope; when the condensed water liquid level lower than 10%; change protected mode over to, stop condensed water and discharge, in order to avoid steam seals in condensation water tank; when condensation liquid level arrival 90% is above; change protected mode over to, safety valve is opened the discharge section condensed water, in order to avoid condensed water directly enters in main steam header.
The beneficial effects of the utility model are:
(1) reduce the investment at user's initial stage, expensive high temperature heavy caliber control valve is canceled, and with the lower common control valve of price, regulate the condensed water liquid level, realize the temperature control effect same with regulating the main steam valve;
(2) utilize the condensed water water replanishing device to reclaim the condensed water that steam produces, directly high-temperature condensation water is added in the secondary returning grid, directly heat, reduced the consumption of steam;
(3) owing to having adopted condensed water loop modulation device, the condensed water loop temperature is lower, and valve breaks down easy to maintenance, to safe operation, brings great benefit.
