Falling-film evaporator blocking fault detection device

Abstract

The invention discloses a falling-film evaporator blocking fault detection device, which comprises a first heating box and a second heating box, wherein the upper right side of the first heating box is provided with a through-flow pipeline; the right side of the through-flow pipeline is provided with a first processing tank; the right side of the second heating box is provided with a second processing tank; and the second heating box is located at the right side of the first processing tank. According to the falling-film evaporator blocking fault detection device disclosed in the invention, asthe controller is arranged, online and concentrated blocking processing is carried out on the falling-film evaporator, the controller receives pressure sensing data at a pressure probe rod and a pressure sensing element, the data are processed, the pressure probe rod feeds back the fluid flow circulation condition inside each heating box, the pressure sensing element feeds back the fluid flow circulation condition of each pipeline structure, the controller sorts the information and controls on and off of a main flow solenoid valve and a side flow solenoid valve and on or off of a motor, and the blocking problem can be timely handled.

Description

technical field [0001] The invention relates to the technical field of fault detection of falling film evaporators, in particular to a blocking fault detection device for falling film evaporators. Background technique [0002] Falling film evaporation is to add the feed liquid from the upper tube box of the heating chamber of the falling film evaporator, and distribute it evenly into each heat exchange tube through the liquid distribution and film forming device. It flows from top to bottom. During the flow, it is heated and vaporized by the shell-side heating medium. The generated steam and liquid phase enter the separation chamber of the evaporator. After the vapor and liquid are fully separated, the steam enters the condenser for condensation (single-effect operation) or enters the lower The single-effect evaporator is used as the heating medium to realize multi-effect operation, and the liquid phase is discharged from the separation chamber. The working efficiency of the...
