Sulfur dioxide transmission remote monitoring system

Abstract

The invention provides a sulfur dioxide transmission remote monitoring system which comprises a DCS control system, an input pipeline, an output pipeline, a monitoring branch and a plurality of transmission branches, wherein the monitoring branch and the plurality of transmission branches are connected between the input pipeline and the output pipeline; all transmission branches are connected in parallel; the monitoring branch is connected with each transmission branch in parallel; a pressure transmitter and a flow transmitter are sequentially arranged on the monitoring branch from the near tothe distant from the input pipeline; the pressure transmitter and the flow transmitter are in signal connection with the DCS control system; and the DCS control system is configured for receiving signal data of the pressure transmitter and the flow transmitter and displaying the signal data. The sulfur dioxide transmission remote monitoring system has the beneficial effects that the pressure transmitter and the flow transmitter are arranged on the monitoring branch, and the signal data is sent to the remote DCS control system, so that the remote monitoring on a sulfur dioxide transmission site can be realized; the monitoring accuracy is improved; the manual inspection is omitted; the labor cost is reduced; and the harm to health of workers is reduced.

Description

technical field [0001] The disclosure relates to the technical field of sulfur dioxide transmission in float glass production, in particular to a remote monitoring system for sulfur dioxide transmission. Background technique [0002] Sulfur dioxide is an important gas used in the production of float glass, which plays an important role in protecting the quality of the glass plate. The sulfur dioxide used in the production process of float glass needs to be gasified in liquid state before entering the slag box. It absorbs a lot of heat. When the ambient temperature is low in winter, the gasification of sulfur dioxide is not sufficient. Once the inspection is not careful, the pressure and flow will be too low, which will affect the quality of the glass plate. [0003] In the prior art, on-site operators need to inspect the pressure and flow in the sulfur dioxide transmission pipeline every 2 hours. Frequent inspections will waste more labor on the one hand, and on the other ha...

[0002] Sulfur dioxide is an important gas used in the production of float glass, which plays an important role in protecting the quality of the glass plate. The sulfur dioxide used in the production process of float glass needs to be gasified in liquid state before entering the slag box. Absorbs a lot of heat. When the ambient temperature is low in winter, the gasification of sulfur dioxide is not sufficient. Once the inspection is not careful, the pressure and flow will be too low, which will affect the quality of the glass plate.

[0003] In the prior art, on-site operators need to inspect the pressure and flow in the sulfur dioxide transmission pipeline every 2 hours. Frequent inspections will waste more labor on the one hand, and on the other hand, sulfur dioxide is a poisonous gas. inhalation and thus presents a significant health hazard, so remote monitoring of sulfur dioxide transport is necessary
