Service life evaluation device and method for pre-filter filter element for condensate polishing

Abstract

The invention discloses a service life evaluation device and method for a pre-filter filter element for condensate polishing. The service life evaluation device of the pre-filter filter element comprises a flow meter (1), a temperature sensor (2), a first pressure meter (3), a second pressure meter (4), a signal converter (5), a single chip microcomputer (6), a display controller (7), a display (8), a computer (9) and a printer (10). The flow meter (1), the temperature sensor (2), the first pressure meter (3) and the second pressure meter (4) are connected with the signal converter (5), the signal converter (5) is connected with the single chip microcomputer (6) connected with the display controller (7) and the computer (9), the display controller (7) is connected with the display (8), and the computer (9) is connected with the printer (10). According to the service life evaluation method of the pre-filter filter element, data acquisition is conducted on pressure drop and flow, and the acquired data and set parameters are compared and analyzed to finish the service life evaluation of the filter element. By means of the method and device, accurate service life evaluation of the pre-filter filter element for the condensate polishing can be conducted, the analysis accordance can be provided for a filter element failure cause.

Description

technical field [0001] The patent of the present invention relates to a device and method for evaluating the operating life of a water treatment filter element, in particular to a device and method for evaluating the operating life of a pre-filter element for condensate polishing. Background technique [0002] Condensed water in a power plant is composed of water condensed in the condenser by the steam after the work done by the steam turbine and the drainage of the heater in the thermal system attached to the steam turbine. Condensed water is an important part of water supply, and its water quality is better. Condensate water and make-up water are combined to form boiler feed water, so the water quality of condensate water and make-up water determines the quality of feed water. Condensed water is formed by the condensation of steam. Theoretically, the water quality should be good. However, due to the leak of cooling water in the condenser and the metal corrosion products o...

AI Technical Summary

Problems solved by technology

If the power plant directly replaces the pre-filter element after a certain period of time, the filter element must be replaced before the end of its life, wasting money

In addition, the traditional evaluation method for the life of the filter element cannot provide strong evidence for the judgment of the cause of the filter element failure.
