Embodiment 1

[0059] Such as figure 1 The shown re-enamelled new reaction tank includes a tank body 1 that has passed the inspection, and the tank body 1 includes an inner cylinder body 2 that has passed the renovation inspection and a new outer jacket 3 that has passed the inspection. The inner cylinder body 2 and the new outer jacket 3 are welded into an integrated structure, and there is a cavity 4 between the two; the upper opening of the inner cylinder body 2 is provided with a large equipment flange 5, and the lower opening is provided with a discharge port flange 23, so The inner wall of the inner cylinder body 2 is coated with a glass-lined glaze layer 6 .

[0060] Such as figure 2 As shown in the inner cylinder body, the inner cylinder body 2 includes a straight cylinder body 2.1 and an inner head piece 2.2 connecting the straight cylinder body 2.1, and there are three sets of butt welds on the outer wall of the inner cylinder body 2, including butt straight welds 2.11, The uppe...

Embodiment 2

[0092] In the re-enameling new reaction tank and its manufacturing process steps of this embodiment, except that the process conditions in the following steps are different, the rest are manufactured according to the steps of Example 1. Wherein, in step 9) and step 11), the firing process of medium-temperature pre-firing, high-temperature sintering, heat preservation, and stage-by-stage controlled firing is adopted during firing. 3 hours, and then fired at 860-960°C for 0.5-1 hour. In step 11), the number of times that the calibrated reaction tank is repeatedly boiled is 5 times.

[0093] The re-enamelling new reaction tank manufactured by adopting precision-controlled internal heating electric furnace, automatic glaze slurry spraying equipment, equipment large flange shaping device and electric heating temperature control insulation cylinder, the maximum and minimum diameter difference of the large flange of the equipment is ≤3mm, the plane The thickness tolerance is ≤1mm, a...

Abstract

The invention relates to a re-lined and renewed reactor after repair and a manufacturing method thereof which are used in the chemical and pharmaceutical industries and belong to the field of pressure vessels. A damaged glass-lined reactor which originally does not conform to the Supervision Regulation on Safety Technology for Pressure Vessel is repaired to become the re-lined and renewed reactor which comprehensively realizes the Supervision Regulation on Safety Technology for Pressure Vessel and can be repaired and utilized multiple times. The manufacturing method is characterized in that a precisely controlled inner heated electric furnace is adopted to implement staged controlled firing and an integral firing process with jackets; and full-automatic glaze slurry spraying equipment, an equipment large flange reshaping device and an electrical heating and temperature controlling insulating cylinder are adopted for manufacturing. The reactor and the manufacturing method have the following advantages: the reactor initiates and lays a foundation for that the manufacturing technology standards of the glass-lined reactors in China all realize the Supervision Regulation on Safety Technology for Pressure Vessel; the integral quality of the reactor is comprehensively and obviously superior to the current national standard; the reactor steps and is developed to innovate and be ahead of the conditions that the international outer heated electric furnace iron billets have no alternative to secondary forming during manufacturing and the core technology of controlled enamelling has the defect of uneven heating; and the reactor sells well in the international markets with the obvious omnibearing technical, quality and economic advantages and has obvious economic benefits and global market competitiveness.

Description

technical field [0001] The invention relates to a repaired and repaired new reaction tank for chemical and pharmaceutical industries and a manufacturing method thereof, belonging to the field of pressurized container equipment for chemical and pharmaceutical industries. Background technique [0002] The glass-lined reaction tank belongs to the reaction equipment of the first and second types of pressure vessels. The tank body is composed of an inner cylinder body (the inner wall is coated with glass-lined glaze) and an outer jacket. At present, the firing of glass-lined reaction tanks at home and abroad is all externally heated furnaces, including the secondary molding of foreign iron blanks. The glass-lined glaze layer on the inner wall of the inner cylinder body with the upper and lower connecting rings (outer jacket transitional structural parts) is first fired, and then the outer jacket is welded and assembled, and the single-sided butt ring welding of the lining plate ...
