Fixed tube plate desulfurization hot water reboiler capable of controlling liquid level

Abstract

The invention relates to the technical field of fixed tube plate desulfurization hot water reboilers, in particular to a fixed tube plate desulfurization hot water reboiler capable of controlling the liquid level. Comprising a shell, a tube box, a tube bundle and a full-flow weir plate, the tube boxes are fixedly connected to the two ends of the shell through flanges, and the tube bundle and the full-flow weir plate are fixedly connected into the shell. The tube bundle comprises fixed tube plates and heat exchange tubes, the fixed tube plates are fixedly connected to the two ends of the shell, and the heat exchange tubes are fixedly connected to the fixed tube plates; a side plate of the full-flow weir plate is axially and fixedly connected into the shell, and a notch is formed in the upper end of the side plate of the full-flow weir plate. A fixed tube plate heat exchanger is adopted, the occupied area is small, a desulfurization liquid evaporation space is arranged, the evaporation requirement is met, the liquid level height is ensured, the flow of shell pass desulfurization liquid can be controlled, a bidirectional flow channel is adopted, the turbulence effect is enhanced, heat transfer is effectively conducted, the temperature difference stress influence is reduced, and the device is compact in structure, safe and reliable.

Description

Technical field [0001] The present invention relates to the field of fixing tube sheet desulfurization hot water reboiler, and more particularly to a fixed tube plate desulfurization hot water reboiler capable of controlling liquid level. Background technique [0002] At present, in the coke oven gas purification carbonate, the desulfurizing solution is indirectly heated by the heat source in the reboiler, and partially vapor distilled acid vapor. The floating head hot water reboiler is generally used for hot water indirect heating of potassium carbonate, hot water pipe, desulfurized, and housing, since the float end is soaked in the desulfurization liquid, the large diameter floating head seal is very difficult In the case of leakage, there is a safety hazard, affecting normal process operation. Inventive content [0003] In order to overcome the deficiencies of the above prior art, the present invention provides a fixed tube sheet dethinated hot water reboiner capable of contr...

AI Technical Summary

Problems solved by technology

Generally, a floating head hot water reboiler is used to indirectly heat the potassium carbonate desulfurization liquid with hot water. The hot water goes through the tube side, and the desulfurization liquid goes through the shell side. Since the floating head end is always immersed in the desulfurization liquid, it is very difficult to seal the large diameter floating head. , Leakage occurs from time to time, there are potential safety hazards, affecting normal process operations
