Condensate Recovery Equipment with Different Pressure in Closed Loop Circulating Steam Boiler

摘要

The present invention is to provide a condensate recovery device having a different pressure of the closed circuit circulation steam boiler for recovering and recycling the condensed water generated by the heat exchange in the heat exchanger is a high-temperature, high-pressure steam generated in a closed circuit circulation steam boiler for heating water. The present invention relates to the use of one device to recover condensate with different pressure to the lower and upper tanks for resupply. To this end, the present invention integrates the condensate collection tank 50 for recovering the condensate 52 generated by heat exchange in the heat exchanger into the lower tank 50a and the upper tank 50b partitioned by the diaphragm 51 and the lower In the diaphragm 51 which divides the tank 50a and the upper tank 50b, upper and lower tank connecting pipes 81 having a check valve 82 are installed at an upper portion thereof, and the lower tank 50a and the condensate suction pipe 61 are provided. And the pump 60 connected to the condensate discharge pipe 63 are driven to the first condensate recovery pipe 62 in which the check valve 65 is installed, and the low pressure condensate 52 is recovered through the lower tank 50a. In this configuration, the condensate discharge tube 63 is extended to the inside of the upper tank 50b to install a vacuum generator 70 in the condensate discharge tube 63, the condensed water having a high pressure in the upper tank (50b) Connecting the second condensate return pipe 64 to the vacuum generator 70 so as to be recovered; The first condensate recovery pipe 62 and the second condensate recovery pipe 64 are connected to the bypass pipe 66, and the bypass pipe 66 is provided with an opening / closing valve 67 for opening and closing a flow path. The second condensate recovery pipe 64 is provided with a valve 64a for opening and closing the flow path so that the valve 64a and the check valve 65 are opened, and the valve 66 of the bypass pipe 66 is closed. When the 60 is driven, the low pressure condensate is recovered to the lower tank 50a through the first condensate recovery pipe 62, and the high pressure condensate is recovered to the upper tank 50b through the second condensate recovery pipe 64. When the check valve 65 and the open / close valve 67 are opened, and the pump 60 is driven while the open / close valve 67 installed in the bypass pipe 66 is opened, the low pressure condensate recovers the first condensate. Recovered to the lower tank (50a) through the pipe 62 and at the same time to be recovered to the upper tank (50b) through the bypass pipe (66) The.
