Problems solved by technology

Neither the steam (air) delivery pump nor the electric hot water pump can be directly applied to the steam heat exchange equipment or the direct connection of the steam pipe network for condensate recovery. A steam trap must be installed behind the steam heat exchange equipment or the steam pipe network. The steam trap performs a steam-water separation, and then the steam trap is connected to the condensed water recovery conveying device for use

Abstract

The invention discloses a condensate water recycling and conveying system and a method thereof. The system comprises a condensate water collection tank connected with a steam conveying main pipeline or a high-temperature condensed water recycling pipeline. The bottom end of the water collection tank is connected with condensate water inlets of condensate water conveying tanks through pipelines. High and low liquid level double-contact electric contact liquid level meters are arranged in the condensate water conveying tanks. Power gas source input ports and power gas discharge pipe openings are formed in the upper ends of the condensate water conveying tanks. Each power gas source input port is connected with a power gas source through a first electromagnetic valve. The power gas discharge pipe openings discharge power gas, input in the condensate water conveying tanks, through second electromagnetic valves. The input power gas presses condensate water in the condensate water conveying tanks to be discharged from condensate water outlets of the condensate water conveying tanks. High liquid level contacts of the double-contact electric contact liquid level meters are connected with the first electromagnetic valves to control the power gas source to be opened and closed. Low liquid level contacts of the double-contact electric contact liquid level meters are connected with the second electromagnetic valves to control the power gas in the condensate water conveying tanks to be discharged and closed.

Description

technical field [0001] The invention relates to a condensed water recycling and conveying system and a method thereof, in particular to an efficient and environmentally friendly condensed water recycling and conveying system and a method based on electric contact liquid level gauge and electromagnetic valve control. Background technique [0002] Steam, as an indispensable power source for modern large-scale steel, chemical, and electric power industries, is being fully utilized. With the establishment of energy-saving enterprises, steam condensate recovery and reuse technology has been widely used. The existing steam condensed water recovery and reuse technology mainly includes two parts: condensed water recovery and condensed water transportation. [0003] Commonly used condensate recovery devices at this stage are divided into open recovery systems and closed recovery systems. The open recovery system is mainly used for drainage recovery of steam pipelines with different ...
