Medium-pressure introduction device and method capable of improving parameters of tail end of low-pressure steam pipe network

Abstract

The invention discloses a medium-pressure introduction device and method capable of improving parameters of the tail end of a low-pressure steam pipe network. The medium-pressure introduction device comprises an inlet introduction pipe and an outlet introduction pipe, wherein an outlet of the inlet introduction pipe is connected with a first steam flow guide pipeline, the first steam flow guide pipeline is connected with a second steam flow guide pipeline through a regulating valve, the second steam flow guide pipeline is connected with an inlet of the outlet introduction pipe, an inlet of the inlet introduction pipe is located in a first steam pipeline, an outlet of the outlet introduction pipe is located in a second steam pipeline, and parameters of steam in the first steam pipeline are larger than those of steam in the second steam pipeline. According to the medium-pressure introduction device and method, the steam parameters of the whole low-pressure steam pipe network or the tail end of the low-pressure steam pipe network are improved to meet user requirements; and meanwhile, the supersaturation degree of low-pressure steam is improved to reduce dewatering and reduce the pipe loss, so that the economic benefit and the social benefit are increased.

Description

technical field [0001] The invention belongs to the technical field of low-pressure steam pipe network parameter adjustment, in particular to a medium-pressure introduction device and method capable of improving the terminal parameters of the low-pressure steam pipe network. Background technique [0002] At present, under the guidance of the government, my country's industrial enterprises are developing in the direction of "intensive, large-scale, large-scale, and integrated" parks, and the scale and number of users of steam heating pipe networks are greatly increasing. In this context, attention needs to be paid to the parameters at the end of the steam network. For long-distance pipe network transportation, the steam pressure and temperature will drop, and the steam parameters may drop below the saturated state, resulting in drainage, increased pipe network loss, and reduced economic benefits. At the same time, individual user steam parameters at the end of the pipe networ...
