Problems solved by technology

At this time, only relying on the heat transfer of the jacket, the heat transfer area is not enough, so that the temperature rise rate of the material in the chemical reaction is slow and the temperature distribution is uneven, which affects the product quality and yield.
At present, foreign countries adopt to increase the number of heat exchangers in the kettle to solve the problem. In addition, the commonly used stainless steel heat exchangers are not resistant to the corrosion of hydrogen ions, and the surface is easy to stick to the material and is not easy to clean, which reduces the heat transfer effect.

Embodiment Construction

[0010] Depend on figure 1, The heat exchanger is welded by a plurality of tube bundles 5 and the liquid collection bag 4 at both ends. The upper and lower ends of the liquid collection bag 4 have water vapor inlet 10 or cooling water outlet 11. At this time, it can be used as a heater. When used as a cooler, it The cooling water outlet 10 and the cooling water inlet 11 are also used. The surface after welding is glass-lined. The lower or upper part of the glass-lined sleeve 1 is sealed with an upper stuffing box 2 or a lower stuffing box 6. The heat exchanger body is sealed by PTFE. The pad 3 is pressed on the lower stuffing box 6, and the upper part is connected with the glass-lined casing 1 by bolts, and the contact surface is sealed with a PTFE pad 3. A jacket 8 is installed around the outside of the glass-lined kettle, and there is a material inlet 12 on the upper part of the kettle. , a material outlet 13 is arranged at the bottom, and a vertical stirrer 9 is housed in t...

Abstract

The invention relates to a tubular heat exchanger in a glass lining kettle, which is welded by a plurality of tube bundles and liquid collecting bags at both ends, wherein water vapor inlets or cooling water outlets are formed at upper and lower ends of the liquid collecting bags; glass is enameled on the welded surface; the lower part or the upper part of a glass lining sleeve is sealed by using an upper filler box or a lower filler box; a heat exchanger body is pressed on the lower filler box by a teflon pad; and the upper part of the heat exchanger body is in bolted connection with the glass lining sleeve.

Description

technical field [0001] The invention relates to a tube-and-tube heat exchanger in a glass-lined kettle, which is composed of a tube bundle, a liquid-collecting bag welded and a glass-lined casing, and belongs to the technical field of reactor heat exchangers in petrochemical equipment. Background technique [0002] Due to the increasing production scale of the petrochemical industry, glass-lined kettles are required to increase their volume, up to 100,000 liters. At this time, only relying on the heat transfer of the jacket, the heat transfer area is not enough, so that the temperature rise rate of the material in the chemical reaction is slow and the temperature distribution is uneven, which affects the product quality and yield. At present, foreign countries have adopted the solution of increasing the number of heat exchangers in the kettle. In addition, the commonly used stainless steel heat exchangers are not resistant to hydrogen ion corrosion, and the surface is easy t...
