Embodiment Construction

[0044] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0045] Such as figure 1 As shown, the embodiment of the present invention provides a method for setting the boiler blowdown time interval, including

[0046] Step 101, obtaining the boiler efficiency within the current blowdown time interval;

[0047] Specifically, the working efficiency of the boiler within the preset blowdown time period may be acquired through the preset blowdown tim...

Abstract

The invention discloses a method and device for setting a blowdown time interval of a boiler. The method comprises the steps that the blowdown time interval is set, and the efficiency of the boiler isobtained; the quality of blow-off water within the blowdown time interval is detected; and according to the quality of the blow-off water and efficiency of the boiler, the optimal blowdown time interval is determined. The device comprises an acquisition module, a detection module and a control module. According to the method and device, for the fixed blowdown mode blowdown interval time adopted by the gas-fired boiler, the blowdown interval time is reasonably adjusted by calculating the efficiency of the boiler within the blowdown interval and detecting the blow-off water quality condition, so that scientific guidance can be provided for specific boiler operation, the heat taken away by blowdown is reduced, the cost is saved, and the efficiency of the boiler is improved.

Description

technical field [0001] The invention relates to the application field of gas-fired boiler blowdown treatment technology, in particular to a method and device for setting a boiler blowdown time interval. Background technique [0002] Due to the clean fuel of gas-fired boilers, the pollution discharge burden is relatively small, so there is relatively little attention paid to the pollution discharge of gas-fired boilers. At present, the time interval of the fixed discharge method in sewage discharge is mostly determined by experience, which lacks certain scientificity. Although the blowdown effect of the boiler is guaranteed. However, unreasonable blowdown intervals lead to greater heat loss and reduced boiler efficiency. Contents of the invention [0003] The invention provides a method and device for setting the time interval of blowdown of boilers. Aiming at the blowdown interval of gas-fired boilers using a fixed blowdown method, the blowdown interval is reasonably adj...
