Abstract

The invention relates to a fire tube type heating furnace with an integral descaling function. The heating furnace comprises a furnace body, wherein a plurality of descaling mechanisms are arranged inthe length directions of a smoke tube and a fire tube in a furnace body, each descaling mechanism is driven by a power mechanism, each descaling mechanism is driven by the power mechanism to move along a guiding mechanism installed in the furnace body, and a scale collecting mechanism communicating with the interior of the furnace body is arranged at the bottom of the furnace body. The heating furnace has the advantages that the smoke tube and the fire tube in the furnace body are subjected to integral descaling, so that scale on the outer surface of the smoke tube and the outer surface of the fire tube can be treated in time, the problems that a fire tube type heating furnace is low in heat efficiency and easy to burst due to the fact that the scale is not timely cleared are solved, andthe heat efficiency is greatly improved.

Description

technical field [0001] The invention relates to a torch-type heating furnace for overall descaling. Background technique [0002] At present, the torch-type heating furnaces used in the three-component polymerization drive process in the oil drilling industry are all traditional heating furnaces without descaling devices (only a few have local descaling devices). During the operation of the heating furnace, the circulating water containing the catalyst in the shell side medium contains calcium carbonate, sediment particles, oil, etc. As a result, after the heating furnace has been running for a period of time, the outer surface of the fire tube and the smoke tube of the heating furnace will form a 3cm-thick generation scale and a 6-7cm-thick deposition scale. This leads to a significant reduction in the thermal efficiency of the heating furnace. Most run at 40%-60%. Cause great waste of energy. What's more serious is that the temperature of the wall of the fire tube outs...
