Embodiment

[0025] The central ventilation control method of the tunnel kiln in this embodiment includes a detection unit and a ventilation control unit, including the following steps:

[0026] (1) Evenly arrange the temperature detection elements at each temperature detection point in the tunnel kiln;

[0027] (2) The signal output ends of the temperature detection elements are respectively connected to filter circuits to filter the clutter interference signals in the detection signals of the temperature detection elements at each detection point;

[0028] (3) connect the signal amplifier circuit after the filtered temperature signal to amplify the temperature signal;

[0029] (4) The amplified temperature signal is encoded to obtain an encoded digital signal for transmission;

[0030] (5) The encoded digital signal is transmitted to the transmission nodes of each control base station through wireless communication, and the transmission nodes are interconnected through repeaters;

Abstract

The invention relates to the technical field of tunnel kiln sintering, and provides a tunnel kiln center ventilation control method. The method includes a detection unit and a ventilation control unit. A temperature detection unit detects temperature signals at respective temperature detection points. The temperature signals undergo filtering, amplification, encoding, transmission, reception at areceiving end, decoding and software analysis and a result is output. The ventilation control unit is in-timely regulated for ventilation control. According to the invention, the method herein can regulate the temperature in the process of sintering in the tunnel kiln in an in-time and accurate manner, has high accuracy and flexibility, and can greatly increase the quality of sintering in the tunnel kiln.

Description

technical field [0001] The invention relates to the technical field of tunnel kiln sintering, in particular to a central ventilation control method of a tunnel kiln. Background technique [0002] Currently used sintering tunnel kilns, including drying and sintering separation type tunnel kiln, linear tunnel kiln, circular tunnel kiln, etc., all adopt tuyere on both sides of the kiln body to control the sintering temperature of the kiln; side ventilation controls the kiln temperature The method is to extract the airflow through the tuyeres on both sides of the kiln, supply oxygen to the kiln for combustion, and control the sintering temperature of the kiln by adjusting the air volume. There are gaps on both sides and the top of the tunnel kiln to facilitate the movement of the kiln car. In this way, while solving the mechanization of the kiln, the problem of "side gap effect" of the tunnel kiln is brought about. That is, the gas flow velocity on both sides and the top of the...
