Description

Steam internal heating pipe of horizontal container

Technical Field

The invention belongs to chemical production equipment, and particularly relates to a steam internal heating pipe of a horizontal container.

Background

In industrial production, materials in a horizontal container need to be heated for heat preservation, condensation prevention and the like. A common heating method is to arrange steam heating coils inside a horizontal vessel. The steam heating coil can provide a larger heat exchange area, and when a large amount of heat is needed, the production requirement can be well met by adopting the coil.

The existing steam heating coil has the following technical problems: the structure is complex, and the requirement on manufacturing precision is high; when the equipment size is larger, the coil pipe is huge in appearance and difficult to manufacture and install; in the operation process of the equipment, the coil pipe is difficult to overhaul; when the equipment requires less heat, the overall performance of the coil is poor.

For the above reasons, there is a need for an improved structure of a steam heating pipe in a horizontal vessel.

Disclosure of Invention

The invention mainly solves the defects in the prior art and provides a steam internal heating pipe for a horizontal container.

The invention is mainly solved by the following technical scheme: the steam inner heating pipe of the horizontal container is characterized by comprising a steam inlet pipe and a horizontal sleeve, wherein the steam inlet pipe extends into the horizontal sleeve and is fixed through a limiting plate, a closed pipe cap is arranged at the inner end of the horizontal sleeve which can extend into the horizontal container, and a liquid outlet is arranged at the outer end of the horizontal sleeve.

Preferably, the inlet end of the steam feeding pipe is connected with the outer end of the horizontal sleeve through a flange and a flange cover, and the inner end of the horizontal sleeve is sealed by a welding pipe cap.

Preferably, the wall of the steam feeding pipe is welded with a plurality of groups of limiting plates.

Preferably, each group of limiting plates comprises an upper limiting plate and two lower limiting plates.

Preferably, the included angle between the two lower limiting plates is 60 degrees.

Preferably, the distance between the limiting plate and the inner wall of the horizontal sleeve is 1.5 mm.

Preferably, the nominal diameter of the horizontal sleeve is 5 times the nominal diameter of the steam feed pipe.

Preferably, the steam feed pipe is offset from the horizontal casing centerline by a distance equal to the nominal diameter of the steam feed pipe.

When the steam internal heating pipe of the horizontal container provided by the invention needs to be heated, steam is fed into one end of the horizontal sleeve through the steam feeding pipe, the steam is condensed and releases heat in the horizontal sleeve, and condensed water is discharged through the liquid outlet at the outer end of the horizontal sleeve.

The diameter and length of the steam feed pipe and the horizontal sleeve in the invention are determined according to the heating requirement calculation.

The number of groups of heating pipes in the steam is determined according to the size of the equipment and the required heat quantity.

The steam inner heating pipe for the horizontal container is simple in structure, convenient to install and maintain, capable of enabling condensed water to naturally flow out and guaranteeing steam heating effect, and particularly suitable for the horizontal container with low heat demand.
