Real-time detection system and method for water seal tank of rotary hearth furnace

Abstract

The invention discloses a real-time detection system for a water seal tank of a rotary hearth furnace. The system comprises a water seal main pipe and a plurality of water seal tanks communicating with the water seal main pipe; the system further comprises a water seal main pipe stop valve arranged on the water seal main pipe and a plurality of water seal straight pipelines, wherein an electric cut-off valve is connected to each water seal straight pipeline, each water seal straight pipeline communicates with the corresponding water seal tank through the electric cut-off valve, and a liquid level meter is arranged in each water seal tank; and the system also comprises a controller separately connected with the electric cut-off valve and the liquid level meter data, and the controller is further provided with an operation terminal HMI. According to the system and the method, the labor intensity of workers can be reduced, the real-time detection of the liquid level and automatic water supplementation for the water seal tanks can be realized, and gas leakage in the furnace can be prevented.

Description

technical field [0001] The invention relates to the field of iron-containing solid waste recycling control, and more specifically relates to a real-time detection system and a detection method for a water-sealed tank of a rotary hearth furnace. Background technique [0002] The rotary hearth furnace generally adopts a mechanized loading and unloading device, the furnace roof and furnace wall are fixed, and the furnace bottom is rotating. The total amount of dust and sludge in iron and steel enterprises is generally 8% to 12% of steel production, and the dust with high content of zinc, sodium, potassium and other elements accounts for about 25% to 30% of the dust in iron and steel plants. If the high dust is directly returned to sintering, it will cause the enrichment of zinc, sodium and potassium elements, which will affect the smooth operation and life of the blast furnace. Rotary hearth furnace technology effectively solves this problem. It directly reduces the dust sludg...

Problems solved by technology

In order to ensure that the liquid level in the inner and outer water seal tanks of the rotary hearth furnace is kept at the required height, the furnace workers need to patrol every 2 hours to check the liquid level in the water seal tank one by one. If the liquid level is lower than the required height, manual work is required. Manually open the water valve to replenish water, such a cyclic inspection cannot monitor the real-time liquid level of the water seal tank in real time, which increases the labor intensity of personnel
