Embodiment approach 1

[0074] Embodiment 1 Online monitoring device:

[0075] Such as figure 1 As shown, an on-line monitoring device for boiling degree of a blast furnace gas boiler economizer of the present invention includes a data acquisition unit, a one-way physical isolation device and a data processing unit, and the data acquisition unit and the data processing unit are separated by one-way physical isolation device to connect.

[0076] Wherein, the data acquisition unit includes a unit distributed control system, a real-time database server and a first switch, and the first switch is respectively connected to the unit distributed control system and the real-time database server. The unit distributed control system collects the operation data of the blast furnace gas boiler, and stores the collected operation data in the real-time database server. The operating data collected by the distributed control system of the unit includes the inlet temperature of the flue gas side of the economizer ...

Embodiment approach 2

[0078] Embodiment 2 online monitoring method:

[0079] The invention provides an online monitoring method for the boiling degree of an economizer of a blast furnace gas boiler, and the key points of its design include the following steps:

[0080] Step 1: The unit distributed control system of the data acquisition unit collects the operation data of the blast furnace gas boiler, and stores the operation data in the real-time database server, and the real-time database server sends the received and stored operation data to the mirror database server for storage .

[0081] Step 2: The calculation server of the data processing unit reads the operating data of the blast furnace gas boiler from the mirror database server through the KKS code point number of the measuring point. The read operating data collected by the distributed control system of the unit includes the inlet temperature of the flue gas side of the economizer θ y，in , economizer flue gas side outlet temperature θ ...

Abstract

The invention discloses a blast-furnace gas boiler economizer boiling degree on-line monitoring device and method. The monitoring device comprises a data acquisition unit and a data processing unit. Operating data of a gas boiler are collected through a unit distributed control system, the collected operating data are stored in a real-time database server and a mirror database server, a calculation server reads the operating data from the mirror database server and processes the operating data to obtain economizer boiling degree calculation results, the calculation results are stored in the mirror database server, a WEB publishing server publishes the calculation results to a user display terminal, and a user can look up the calculation results in real time through the user display terminal and master the operating conditions of an economizer in time. If the economizer boiling degree excesses a set upper limit value, the user can lower the economizer boiling degree in time through the boiler operation adjustment, so that the economizer is in the safety state, the safety operation of the blast-furnace gas boiler is accordingly guaranteed, and the service life of the blast-furnace gas boiler economizer is accordingly prolonged.

Description

technical field [0001] The invention relates to the boiler technology field of thermal energy engineering, in particular to an online monitoring device for the boiling degree of an economizer of a blast furnace gas boiler and a monitoring method based on the monitoring device. Background technique [0002] Iron and steel enterprises produce a large amount of by-product gas during the smelting process, including blast furnace gas, converter gas and coke oven gas. Among them, blast furnace gas is produced in the ironmaking process, and its quantity is the largest among the three types of gas. However, due to the high nitrogen content of blast furnace gas, low calorific value and poor combustion stability, many iron and steel plants do not fully utilize blast furnace gas, and a large amount of blast furnace gas is directly released, resulting in a huge waste of energy. How to make good use of the precious blast furnace gas resources has always been a common concern of relevant...
