Extractable fire cylinder smoke tube

Abstract

The invention provides an extractable fire cylinder smoke tube which comprises a fire cylinder smoke box, a vessel flange, a sliding channel, a tube body rear sealed end, a fire cylinder smoke tube body and an explosion door, wherein a heating furnace body adopts a dual-return travel structure; the fire cylinder smoke tube body and the fire cylinder smoke box are connected via the vessel flange with an equipment cylinder to form a whole; a support is arranged at the bottom of the fire cylinder smoke box; the sliding channel is arranged in the cylinder body of the fire cylinder smoke box; a lifting lug capable of lifting is arranged at the upper part of the fire cylinder smoke box; the cylinder rear sealed end is located at the rear part of the fire cylinder smoke box; both the explosion door and the cylinder rear sealed end adopt a packing box type structure; the fire cylinder smoke tube is simple and reasonable in structure, safe and convenient to use and convenient to maintain, can be dismounted and replaced by applying a gantry and a lifting hoist on application site rapidly, can quickly recover production, and satisfies demand for field production.

Description

technical field [0001] The invention relates to a split heating furnace with pressure, in particular to a fire pipe of the heating furnace. Background technique [0002] Corrosion of torches, smoke pipes and coils is a common phenomenon in commonly used heating furnaces in oil fields. Once corroded and perforated, maintenance is very troublesome. Especially for large-scale pressurized split-type heating furnaces, the bottom is the heating furnace body (i.e. steam boiler), the upper part is a heat exchanger, and the furnace body has a large diameter, and in remote areas, there is often no demineralized water in the shell side of the heating furnace It can be added that the outer wall of the torch may be scaled, resulting in poor heat transfer, and may also damage the torch due to local high temperature. Once damage is caused at the site of use, a hot fire report must be issued for maintenance, and various lifting, disassembling, cutting tools, etc. must be used. Contents o...

Problems solved by technology

[0002] In the heating furnaces commonly used in oil fields, corrosion of torches, smoke pipes and coils is a common phenomenon. Once corroded and perforated, maintenance is very troublesome

Especially for large-scale pressurized split-type heating furnaces, the bottom is the heating furnace body (i.e. steam boiler), the upper part is a heat exchanger, and the diameter of the furnace body is relatively large, and in remote areas, there is often no softened water in the shell side of the heating furnace It can be added that the outer wall of the torch may be scaled, resulting in poor heat transfer, and may also damage the torch due to local high temperature

Once damage is caused at the site of use, a hot fire report must be issued for maintenance, and various lifting, disassembling, cutting tools, etc. must be used for maintenance.
