Embodiment Construction

[0036] In this manual, the unit of length, width and thickness without a clear unit is mm.

[0037] Example: a chlorination furnace used for an annual output of 60,000 tons of titanium dioxide. In this embodiment, the tolerance of cylinder length is ±20mm, and the tolerance of outer circumference is ±17.65 / 17.5mm.

[0038] After the material arrives and passes the acceptance check, the barrel is blanked according to the layout drawing, and the beveling machine is used for groove processing.

[0039] The outer diameter of the upper cylinder of the chlorination furnace is φ7060㎜, the thickness of the cylinder wall is δ=50㎜, and the blanking dimensions of the steel plate are: length 9000×width 2000×thickness 50, four pieces, length 4023×width There are two pieces of 2000×thickness of 50; a total of 6 pieces of steel plates for upper cylinder and blanking.

[0040] Among them, two steel plates with a width of 9000×2000×50 and a length of 4023×2000×50 are welded into the first an...

Abstract

The invention discloses a making and construction method of a chlorination furnace. The making and construction method comprises the following steps of carrying out processing and blanking in a factory, carrying out installation on a construction site, carrying out integral heat treatment, carrying out a hydraulic pressure test and an air-tight test, and carrying out equipment painting. The chlorination furnace comprises an upper head, an upper cylindrical shell, a lower cylindrical shell and an outer jacket. The upper head is arranged on the upper cylindrical shell. The upper cylindrical shell is arranged on the lower cylindrical shell. The outer jacket surrounds the lower cylindrical shell. Support annular plates are welded on the upper cylindrical shell. Multiple support rib plates and water holes are arranged on the support annular plate at equal intervals. The support rib plate is provided with a water groove. The upper head is provided with four water outlet weir plates. The water outlet weir plates are provided with concave-convex teeth and water holes. A lower part of the lower cylindrical shell is provided with a lower head. The wall plate groove of 50mm is made by butt joint of steel plates having different thickness, and then is processed. In construction, the groove is manufactured by flame machining and is rubbed flat by a grinding machine so that the construction period is reduced and grinding wheel sheet consumption is greatly reduced and manpower is saved.

Description

technical field [0001] The invention belongs to large thin-walled pressure vessels. In particular, it involves the production and construction method of the boiling chlorination furnace for the chlorination process titanium dioxide project below 60kt / a. Background technique [0002] The chlorination furnace is the core equipment of the chlorination titanium dioxide project process. Its main media include: rutile, chlorine, oxygen, TiCl4 and other by-products. The reaction temperature is high, about 900-1000°C, and the upper temperature is reduced to 300°C by quenching process. . In China, similar containers are produced in factories and hoisted on site as a whole. [0003] The equipment of the chlorination furnace has a large diameter and belongs to a large thin-walled pressure vessel. The overall installation is in the form of hanging from a high place, and it cannot be manufactured on site. Generally, it is manufactured in a large pressure vessel manufacturer, and it is ...
