Problems solved by technology

In the conventional acid vapor condenser, the condensate will reach the follow-up acid vapor cooler together with the acid vapor, and the condensate will be further cooled along with the acid vapor, resulting in a loss of cooling capacity, as the temperature of the condensate drops to unsaturated state, and then absorb acid vapor (hydrogen sulfide gas), and finally enter the rich liquid tank for analysis again, resulting in increased process load and increased energy consumption

Abstract

The invention relates to a condenser for acid steam. The condenser comprises a casing, heat exchange tubes, a baffle plate, an acid steam inlet and an acid steam outlet. The heat exchange tubes and the baffle plate are arranged in the casing. The acid steam inlet is formed in the top of the casing, and the acid steam outlet is formed in the bottom of the casing. A liquid discharging port is formed in the bottom of the baffle plate to be used for discharging condensates. The acid steam outlet is of a pulling bushing structure. The condenser has the advantages that moisture included in condensate acid steam is discharged efficiently, and the condensates produced during condensing can be discharged through the liquid discharging port and a condensate outlet, so that losses of refrigeration capacity due to the fact that the condensates enter a subsequent acid steam cooler are prevented, and meanwhile, increasing of system loads due to the fact that the condensates absorb the acid steam again is prevented.

Description

technical field [0001] The invention relates to an acid vapor condenser used in a vacuum carbonate desulfurization process in the coking industry. Background technique [0002] The acid vapor discharged from the top of the desorption tower in the vacuum carbonate desulfurization process has a high temperature and needs to be condensed to reduce the water content in it. In the conventional acid vapor condenser, the condensate will reach the follow-up acid vapor cooler together with the acid vapor, and the condensate will be further cooled along with the acid vapor, resulting in a loss of cooling capacity, as the temperature of the condensate drops to unsaturated state, and then absorb acid vapor (hydrogen sulfide gas), and finally enter the rich liquid tank for analysis again, resulting in increased process load and increased energy consumption. Contents of the invention [0003] In order to overcome the deficiencies in the prior art, the purpose of the present invention i...
