Description

Pressure release device for calciner of carbon plant

Technical Field

The utility model relates to the technical field of carbon processing environmental protection equipment, in particular to a pressure release device of a calciner of a carbon plant.

Background

The calcining workshop of the carbon plant uses a calcining furnace to calcine the petroleum coke, so that the moisture and volatile matters in the petroleum coke are removed, and the product quality is improved. Petroleum coke is discharged from the top of the calciner to the bottom. The novel calciner is provided with a feed box at the bottom of the furnace, namely at the lower part of the discharger, so that the calciner can normally operate when the calcined coke horizontal vibration conveying device is overhauled or damaged, and the yield of the calciner is improved. When the volatile matters in the raw materials are not completely combusted in the furnace chamber and enter the material box, the volatile matters are combusted in contact with air in the material box to form positive pressure, so that pressure relief is needed, and if a pressure relief port is not formed in the material box, the material box can explode to cause a safety accident. In general, a pressure relief valve is mounted on the bin in such a way that the bin is depressurized. However, because the working condition of the calciner is complex, the pressure value in the material box is continuously changed, so the pressure relief time is not fixed and random occurrence occurs according to the calcination working condition; and the toxic and harmful gas generated during pressure relief is a serious test for the post environment and the physical and psychological health of operators. Thus requiring a pressure relief device to complete the pressure relief to the tank.
