Description

Technical Field

[0001] This utility model belongs to the field of condensate recovery technology, specifically relating to a superheated condensate recovery device. Background Technology

[0002] In the ultra-optimal Claus sulfur recovery process, sulfur dioxide and hydrogen sulfide react to form sulfur under the acceleration of a catalyst, generating a large amount of heat. To ensure that production proceeds in a direction favorable to sulfur formation, water is needed to cool the generated gaseous sulfur. After being heated by the heat of reaction, the water not only produces steam to supply the system, but also requires the discharge and replacement of a large amount of hot water from the sulfur condenser. Simultaneously, to ensure the fluidity of the sulfur, continuous steam tracing is required for the sulfur pipelines, resulting in a large amount of steam condensate.

[0003] The original equipment collected the waste boiler hot water and steam condensate in the drain tank. The waste boiler hot water entered the tank from the middle, and the condensate entered the tank from the top. As a result, the overheated condensate in the drain tank was too hot to be returned to the production system and could only be discharged into the sewage system through the ditch, resulting in a waste of water resources.

[0004] Therefore, improvements are urgently needed. Utility Model Content

[0005] To address the aforementioned deficiencies in the existing technology, this utility model provides a superheated condensate recovery device, comprising a sewage tank, a steam condensate pipeline, a waste boiler water pipeline, and a circulating water main pipeline. The steam condensate pipeline is used to introduce steam condensate, the waste boiler water pipeline is used to introduce waste boiler water, and the circulating water main pipeline is used to introduce circulating water. A first inlet pipeline is connected to the upper part of the sewage tank, a second inlet pipeline is connected to the middle part of the sewage tank, and an outlet pipeline is connected to the bottom of the sewage tank, which is connected to the circulating water system. Both the steam condensate pipeline and the waste boiler water pipeline are connected to the second inlet pipeline. The circulating water main pipeline is connected to a first circulating water branch pipeline and a second circulating water branch pipeline. The first circulating water branch pipeline is connected to the first inlet pipeline, and the second circulating water branch pipeline is connected to the outlet pipeline.

[0012] The working principle and beneficial effects of this utility model are as follows: In order to realize the reuse of superheated condensate, the structure of the sewage tank is modified. Waste boiler hot water and steam condensate are introduced into the sewage tank from the middle. A stream of circulating water is added to the upper part of the sewage tank to cool the incoming superheated condensate. A stream of circulating water is also added to the outlet pipe of the sewage tank to cool the superheated condensate and maintain the liquid level of the sewage tank. The condensate is then sent to the circulating water system by a water pump, realizing the reuse of superheated condensate, saving water resources and reducing the production cost of the system.
