Steam condensation water recycling boiler system based on closed type recycling

Abstract

The invention provides a steam condensation water recycling boiler system based on closed type recycling. The steam condensation water recycling boiler system comprises a boiler, a workshop heat utilization device, steam traps, a closed type recycling device subsystem, a water tank for the closed type recycling device subsystem, wherein the boiler, the workshop heat utilization device, the steam traps, the closed type recycling device subsystem and the water tank for the closed type recycling device subsystem are sequentially connected to form a loop through a steam condensation water pipeline. A boiler water supplementing pump is arranged at the lower portion of the water tank for the closed type recycling device subsystem. A jet flow entraining device is connected between the boiler water supplementing pump and the water tank for the closed type recycling device subsystem in parallel. A one-time softening water tank is arranged above the water tank for the closed type recycling device subsystem. A boiler water feeding and supplementing mother pipeline is connected between an original boiler water feed pump and the jet flow entraining device in parallel. After being subjected to closed type recycling through a steam utilizing workshop, condensation water and flash dead steam are conveyed to a boiler room through a pipeline in a long-distance manner to be combined and matched with an intelligent recycling device, and therefore the normal recycling of working medium water of the industrial boiler is achieved. The structure is compact, the design is ingenious, and large-scale application and popularization are facilitated.

Description

technical field [0001] The invention relates to a steam condensed water recycling system, in particular to a steam condensed water recycling boiler system based on closed recovery. Background technique [0002] The thermal system of the industrial steam boiler uses demineralized water as the carrier of heat energy, and evaporates into steam in the boiler. The steam is transported to the heat-consuming equipment along the pipeline, and after doing work, the latent heat is released to become condensed water of corresponding pressure. In order to realize the recycling of hydraulic fluid, especially the recycling of high-temperature condensate and corresponding flash exhaust steam based on the characteristics of energy saving and emission reduction, people have found many technical measures for the recovery and use of high-temperature condensate, but the existing The measures and methods all emphasize the normal operation and discharge of condensed water without affecting the p...

AI Technical Summary

Problems solved by technology

However, for some heat-consuming equipment, the distance between the workshop and the boiler room is relatively far, for example, the distance between the pipelines is hundreds of meters or even thousands of meters, and there are many climbing and turning along the way, and there are even multiple workshops where the condensate needs to be routed from the branch road. In the complex situation where the pipeline and the main pipeline are in parallel, it is difficult to directly push the condensed water to the boiler room for a long distance by relying on the back pressure of the steam trap

The specific performance is that the resistance along the way is high, the pipeline water hammer is serious, and the condensate drainage ability of some equipment is reduced, so the normal recovery of condensate and exhaust steam cannot be realized, and even pipelines and equipment are damaged.
