Furnace pressure detection control system for high-boron glass total oxygen furnace

Abstract

The invention discloses a furnace pressure detection control system for a high-boron glass total oxygen furnace, and relates to the technical field of glass manufacturing equipment. The system comprises a melting furnace, the melting furnace is provided with a melting furnace breast wall, a pressure leading position is arranged on the melting furnace breast wall, and the system further comprises asteel plate, a first pressure guide pipe, a heat-resistant metal hose, a second pressure guide pipe, a first heat-resistant four-way pipe fitting, a heat-resistant movable flange, a third pressure guide pipe, a fourth pressure guide pipe, a second heat-resistant four-way pipe fitting, a fifth pressure guide pipe, a four-way pipe fitting, an electric ball valve, a sixth pressure guide pipe, a reducer pipe, a stainless steel seamless pipe, a micro differential pressure transmitter, a control station and an industrial personnel computer. The control and detection of the electric ball valve and the micro differential pressure transmitter are collected through the control, collected signals are transmitted to the industrial personal computer, the whole detection process is full-automatic, useis convenient, and the measurement precision is high.

Description

technical field [0001] The invention relates to the technical field of glass manufacturing equipment, in particular to a kiln pressure detection and control system for a high boron glass full-oxygen kiln. Background technique [0002] At present, the device used to detect the kiln pressure on the glass melting furnace is only a pressure-taking steel pipe leading out of the kiln and directly connected to the differential pressure transmitter. This simple pressure-taking device is in the traditional way (fuel + air combustion system) combustion technology There is no problem on the glass furnace. However, as the country's requirements for energy saving and emission reduction and environmental protection awareness continue to increase; with the development of national science and technology, people's living standards are getting higher and higher, and the demand for fire-resistant glass is bound to increase. become more and more common. In order to produce high-quality high-b...

Problems solved by technology

In order to produce high-quality high-boron glass, it is necessary to solve the problem of high-boron all-oxygen kiln combustion process. The high-temperature combustion of batch materials at high temperature forms a large amount of boric acid-containing water vapor generated by the combination of hydrogen molecules in boric acid and oxygen. The traditional pressure taking method Not only is it impossible to achieve post-maintenance, water vapor will also cause distortion of the measured value of the differential pressure transmitter, which cannot meet the requirements of process production data and directly affect the quality of glass
