Detailed Description
The present invention provides a steam condensate recycling system, and the purpose, technical scheme and effect of the present invention are more clear and definite, and the present invention is further described in detail below. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.
Referring to fig. 1, the present invention provides a steam condensate recycling system.
The steam condensate recycling system comprises a steam pipe 1, a paper machine drying cylinder 2, a condensate pipe 3, a vacuum groove 4 and a first water pump 501 which are connected in sequence. The first water pump 501 is sequentially connected with the hot water tank 7, the second water pump 502, the filter 8 and the starch diluting tank 9; the first water pump is provided with a first outlet conduit 51, which is provided with a first valve 61. In practice, a plurality of paper machine cylinders may be provided in the paper machine cylinder station, only one of which is schematically shown in the drawings.
Further, the first water pump is provided with a second outlet conduit 52, which is provided with a second valve 62. The second outlet pipeline is arranged to facilitate the improvement of the operation flexibility, and the second valve is opened to discharge the redundant steam condensate to other equipment, such as a boiler (not shown in the figure and not within the protection scope of the utility model).
Preferably, the first and second valves are electrically-controlled valves.
Preferably, the filter has a filtration accuracy of 50 microns.
Further, the hot water tank is provided with a thermometer (not shown in the figure) for detecting the temperature of the water in the hot water tank.
Preferably, the hot water tank is provided with a liquid level gauge (not shown in the figure) for controlling the liquid level of the hot water tank.
Preferably, the filters are arranged in two (only one filter is shown in the figure) side by side, so that one filter is ready for use and one filter is in operation.
In actual use, the first valve, the second valve, the first water pump, the second water pump, the thermometer and the liquid level meter are all connected with an automatic control system (not shown in the figure and not within the protection scope of the utility model) of a paper mill. When the temperature of the hot water tank is lower than a set value, opening the first valve and closing the second valve; when the temperature of the hot water tank is higher than the set value, the first valve is closed, and the second valve is opened. And the steam condensate water is filtered by a filter and then is sent to a starch diluting tank. After the scheme is implemented, the clean water does not need to be heated by a steam heating coil pipe and then sent to the powder diluting tank like the prior art. The steam condensate water generated at the station of the paper machine dryer can be fully recycled, the use of clear water and steam at the starch dilution station can be saved, the use amount of coal can be reduced, the waste discharge can be reduced, and the purposes of energy conservation and consumption reduction can be achieved.
It should be understood that the technical solutions and the inventive concepts according to the present invention may be equally replaced or changed by those skilled in the art, and all such changes or substitutions should fall within the protection scope of the present invention.
