Embodiment 1

[0062] Such as Figure 1a The new glass-lined reaction tank shown includes a qualified tank body 1, and the tank body 1 includes a qualified new inner cylinder body 2, a qualified new outer jacket 3 and multiple sets of reinforced steel plates 4. The new inner cylinder body 2 and the new outer jacket 3 are welded into an integrated structure, and a cavity 6 is formed between the two; the upper opening of the new inner cylinder body 2 is provided with a large flange 5 for equipment, and the lower opening is provided with a There is a discharge port flange 24, and the inner wall of the new inner cylinder body 2 is coated with a glass-lined glaze layer 7.

[0063] Such as figure 2 As shown in the new inner cylinder body, the new 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 new inner cylinder body 2, including butt direct welding s...

Embodiment 2

[0094] In the new glass-lined reaction tank of this embodiment and its manufacturing process steps, except that the process conditions in the following steps are different, the others are manufactured according to the steps of Example 1. Wherein, in step 9) and step 10), the firing process of medium-temperature pre-firing, high-temperature sintering, heat preservation, and stage-by-stage controlled firing is adopted during firing. Heat preservation, and then use 450-750°C to heat up and pre-fire and heat-preserve. The time for temperature-raising pre-fire and heat preservation is 2-4 hours in total, and then use 700-920°C for high-temperature firing and heat preservation. The time for high-temperature firing and heat preservation is 1 hour in total. -1.5 hours. The precision-controlled internal heating electric furnace with intelligent temperature program control / regulation / recorder can accurately compile, set and automatically record the firing temperature curves of the whole...

Abstract

The invention relates to a new glass-lined reactor and a manufacturing method thereof which are used in the chemical and pharmaceutical industries and belong to the field of pressure vessels. The reactor is characterized in that new inner cylinder bodies and new outer jackets are welded into an integral structure; glass-lined protection glaze layers are coated and fired on the surfaces of butt welds on the inner cylinder bodies and the outer jackets; and the Supervision Regulation on Safety Technology for Pressure Vessel is comprehensively realized. The manufacturing method is characterized in that a precisely controlled inner heated electric furnace formed by intelligent temperature program controllers / regulators / recorders is adopted to implement staged controlled firing and an integral firing process with jackets; and full-automatic glaze slurry spraying equipment 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 and initiates and lays a foundation for datamation and automation of the core technology of controlled enamelling; the integral quality of the reactor is 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 integral quality of the reactor is superior to the international leading level, therefore the reactor has global market competitiveness.

Description

technical field [0001] The invention relates to a new glass-lined 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 at the upp...
