Energy-saving pump for recycling steam and condensed water

Abstract

The invention discloses an energy-saving steam condensed water recovery pump, which includes a frame, a crankcase, a pump body and a pipeline system. On the crankshaft, the crankshaft is fixed on the crankshaft end cover through bearings, the crankcase is fixed on the frame at the same time, the crankshaft connecting rod is installed on the crankshaft, the piston pin is installed on the crankshaft connecting rod, and the piston pin is fixed on the connecting support of the piston rod. The piston rod connection support is fixed on the piston rod; the piston is fixed on the piston rod, the front cover of the piston cylinder and the rear cover of the piston cylinder are fixed on the frame; the condensate water pipe of the equipment is connected to the condensate recovery tank, and the condensate recovery tank passes through The pipe is connected to the filter, the filter is connected to the water inlet one-way valve through a tee, the water inlet one-way valve is connected to the pump body through the drain pipe, and the pump body is connected to the water outlet one-way valve through the drain pipe, and the water outlet one-way valve The valve is connected to the boiler inlet pipe through another tee. Therefore, the transmission is stable and the wear is small.

Description

technical field [0001] The invention belongs to boiler auxiliary equipment, in particular to an energy-saving device for recovering boiler steam condensed water. Background technique [0002] The steam boiler is a large energy-consuming water consumer in my country. The high-pressure steam produced by the steam boiler and the condensed water discharged after being used by the steam equipment have a high temperature and a large waste heat resource, and the water quality is excellent. The condensed water is similar to pure distilled water. directly as boiler feed water. Therefore, condensate recovery is an important energy-saving measure, but most enterprises encounter a technical difficulty in the process of condensate recovery, that is, the condensate itself has very high pressure, and these high-pressure condensate must be pumped by high-pressure water In general, the sealing elements around the shaft of the water pump can hardly withstand the impact and pressure of high-pr...

Problems solved by technology

Therefore, condensate recovery is an important energy-saving measure, but most enterprises encounter a technical difficulty in the process of condensate recovery, that is, the condensate itself has very high pressure, and these high-pressure condensate must be pumped by high-pressure water into the boiler, but generally the sealing elements around the pump shaft can hardly withstand the impact and pressure of high-pressure water, the water pump basically cannot start and work normally, and the water pump is easily damaged

Therefore, most of the existing boiler systems adopt open recovery, that is, the condensed water generated by the heating equipment is directly led to the cement pool or iron tank connected to the atmosphere through the condensed water recovery pipe, and then the water is cooled to below 70 degrees. Then the water pump is transported to the boiler through the water inlet pipe. This open recovery method can only recover a small part of the heat energy of the condensed water, and the condensed water is in contact with the atmosphere during the recovery process, which is easy to cause secondary pollution, and the impurities and oxygen in the water increase greatly. The good quality of condensed water similar to distilled water is lost, and water quality treatment processes such as softening and deaeration must be carried out
