Abstract

A vapor-liquid micro-negative pressure condensed water recycling system comprises a condensed water collection device and a condensed water recycling device, wherein the condensed water collection device comprises a condensed water collection tank and a flash evaporation ejector; the condensed water collection tank comprises a recycling cavity and a disposal cavity; the first condensed water inlet and the first steam exhaust port are arranged on the upper side of the recycling cavity; while steam-water mixing inlet and the second steam exhaust port are arranged on the upper side of the disposal cavity; one path of the first steam exhaust port connects the entrance of the flash evaporation ejector, the outlet of which connects the steam-water mixing inlet; the first condensed water outlet is arranged at the bottom of the disposal cavity. The first condensed water outlet is connected through delivery pump to the entrance of the three-way valve. One path of the outlet of three-way valve is connected to recycling pipes of the condensed water, and the other path is connected to the flash evaporation ejector. Inlet and outlet of the recycling pipes of the condensed water is connected to the recycling device of the condensed water. The vapor-liquid micro-negative pressure condensed water recycling systemis characterized by the advantage of opening and closed recycling system and by the solution to recycling of condensed water and smooth return of low pressure condensed water.

Description

technical field [0001] The invention relates to the technical field of steam condensed water recovery and utilization, in particular to a vapor-liquid split micro-negative pressure steam condensed water recovery system. Background technique [0002] Steam condensate recovery is mainly used in tobacco, food, electronics, petroleum, chemical and other industries. The existing steam condensate recovery methods are divided into two types: open recovery system and closed recovery system. The open recovery system has the advantage of stable system operation, but due to the secondary flash evaporation, the heat loss accounts for 50%-70% of the output heat of the steam trap, and the lost demineralized water accounts for 5%-20% of the condensed water, which not only causes The heat recovery is not complete, and it is easy to cause serious heat pollution and noise pollution to the environment. For example, the condensed water will be secondary polluted by oxygen and carbon dioxide in...
