Abstract
The invention discloses a seal water system for a pump station. A water outlet end of a water taking pump is connected with a water inlet end of a pipeline mixer through a pipeline; a chemical adding device is connected with the water inlet end of the pipeline mixer through a pipeline; a water outlet end of the pipeline mixer is connected with a water inlet end of a sand filter through a pipeline; a filtered water outlet end of the sand filter is connected with a water inlet end of a stainless steel water tank through a pipeline; a mud water outlet end of the sand filter is connected with a water inlet end of a pump station forebay through a pipeline; a water outlet end of the stainless steel water tank is connected with a water inlet end of a seal water pipe network through a water delivery pump; a water outlet end of the seal water pipe network is connected with a water inlet end of a water pump stuffing box; a water outlet end of the water pump stuffing box is connected with the water inlet end of the pump station forebay through a sewer. The number of the pump stations with application of old seal water systems is not smaller than 50, and if the project can be extended in Shanghai, 15 million yuan can be saved every year on the basis that 0.3 million yuan can be saved by each pump station every year through rough calculation.
Description
technical field [0001] The invention relates to the technical field of sewage treatment systems, specifically the sealing water system of a pumping station, and particularly relates to its system connection structure. Background technique [0002] There are 6 large mixed flow pumps in the SB pumping station of Shanghai Urban Drainage Co., Ltd. Bailonggang Sewage Delivery Branch. This type of water pump has three water cooling protection systems of cooling water for the upper and lower bearings and sealing water for the pump stuffing box. Both the cooling water and the sealing water are supplied with tap water, and the cooling water of the bearings adopts an internal circulation device, and the loss is acceptable. However, due to the working principle, the sealing water is mixed with the sewage and directly discharged into the sewer, which cannot be recycled. According to the statistical analysis of the operation, the monthly water consumption of the pumping station is about...
