Problems solved by technology

The main method to ensure the salt concentration of the boiler water is blowdown. In the actual operation process, if the blowdown of the boiler is insufficient, the salt concentration of the boiler water will be too high and affect the safe operation of the boiler. If the blowdown is too large, a large amount of high-temperature and high-pressure water will be discharged, causing heat and Huge waste of water resources
At present, most boilers in China currently use the method of artificially timed sewage discharge. It is difficult to control the sewage discharge in an optimal state, which often causes excessive waste of heat energy. Therefore, it is necessary to study the minimum sewage discharge, control the boiler water to meet the standard, ensure the safe operation of the boiler, and improve Thermal efficiency, saving energy has important economic and social benefits

Embodiment Construction

[0044] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0045] In this article, if there is no special explanation, when involving formulas, " / " means division, and "×" and "*" mean multiplication.

[0046] A boiler thermal system. The boiler thermal system includes multiple boilers 14 for generating steam. The multiple boilers 14 are respectively connected to a central monitoring and diagnosis system 20 for monitoring the operation of the boilers.

[0047] By integrating the operation monitoring automation system of all boilers into a centralized monitoring automation monitoring platform, that is, the central monitoring and diagnosis system 20, this platform can realize automatic online monitoring of various parameters of all boilers, and solve the automation island existing in the existing boiler operation question.

[0048] Further, such as figure 1 As shown, the boiler thermal system incl...

Abstract

The invention provides an intelligent blowdown boiler which comprises an automatic control blowdown system. The automatic control blowdown system is automatically controlled according to the amount of steam generated by the boiler and the amount of water input into the boiler. The water supply amount and the generated steam amount of each boiler are monitored in real time, so that the dynamic relation of the water supply amount and the generated steam amount is obtained, whether the blowdown system of the boiler works normally or not is judged, and waste of a large amount of heat energy waste caused by faults of the blowdown system of the boiler is avoided.

Description

technical field [0001] The invention belongs to the field of boilers and belongs to the field of F22. Background technique [0002] During the operation of the boiler, the boiler water is concentrated with the steam output, so the salt concentration of the boiler water must be controlled to ensure the quality of the steam and the safety of the boiler operation. The main method to ensure the salt concentration of the boiler water is blowdown. In the actual operation process, if the blowdown of the boiler is insufficient, the salt concentration of the boiler water will be too high and affect the safe operation of the boiler. If the blowdown is too large, a large amount of high-temperature and high-pressure water will be discharged, causing heat and Huge waste of water resources. At present, most boilers in China currently use the method of artificially timed sewage discharge. It is difficult to control the sewage discharge in an optimal state, which often causes excessive was...
