Problems solved by technology

The research team of our unit has been committed to improving the performance of glass-lined and glass-lined equipment for many years. The products currently developed have greatly improved in terms of fish scale resistance and corrosion resistance. Glaze can be firmly combined with the embryo body, reducing fish scale explosion, the surface is beautiful and clean, and has good acid corrosion resistance, but the alkali corrosion resistance is average, which limits its application range

Abstract

The invention discloses a high-strength corrosion-resistant glass-lined reactor, which comprises a jacket, a tank body, a stirrer, an upper head, a lower head, a sight glass manhole, a thermometer nozzle, a feed port, and a discharge port, wherein the jacket is arranged at the outer side of the tank body, and a plurality of mounting and positioning devices are arranged outside the jacket at equal angles; a steam inlet is formed in the upper part of the jacket, and a vent port is formed in one side of the steam inlet; a condensate water outlet is formed in the bottom of the jacket, and a high-necked flange is welded on the feed port; a high-necked flange is welded on the sight glass manhole, and a high-necked flange is welded on the thermometer nozzle; a high-necked flange is welded on the discharge port, a bottom glaze layer is arranged on the inner side wall of the tank body, and a surface glaze layer is arranged on the bottom glaze layer; bottom glaze layers are arranged on the inner side walls, end surfaces and grooves of the high-necked flanges, and surface glaze layers are arranged on the bottom glaze layers. The high-necked flanges are added for welding of openings, so that the number of punch forming opening R parts is decreased, the effective thickness of equipment is directly increased, the compressive strength is relatively improved, and the safe operation of the equipment is ensured.

Description

technical field [0001] The invention belongs to the technical field of glass-lined chemical equipment, in particular to a high-strength corrosion-resistant glass-lined reaction kettle. Background technique [0002] For the glass-lined reactor, the glass-lined reactor is to line the inner surface of the steel container with high-silica-containing glass, which is firmly adhered to the metal surface after high-temperature burning to become a composite product. It has the characteristics of glass With the dual advantages of excellent stability and metal strength, it is an excellent corrosion-resistant equipment. [0003] In the existing glass-lined reactor, there are high-necked flanges at all openings such as the upper head, the lower head, the sight glass manhole, the nozzle of the thermometer, the feed port, and the discharge port, so that the high-neck flange is obtained. There are the following two methods: 1) The high neck flange is obtained by stamping, and the thickness...
