Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of heat exchange of cold seal water between a gasification workshop and an ammonia-alcohol workshop, and particularly relates to a parallel system of cold seal water heat exchangers between a gasification workshop and an ammonia-alcohol workshop. Background Art
[0002] In the gasification workshop and the ammonia-alcohol workshop, hot seal water (with a pressure of 9 Mpa and a temperature of 130 °C) is exchanged into cold seal water (with a pressure of 9 MPa and a temperature of 50 °C) through circulating water (with a pressure of 0.4 Mpa and a temperature of 28 °C) by a gasification heat exchanger and an ammonia-alcohol heat exchanger respectively, and is used as mechanical seal water for each user in the gasification and ammonia-alcohol workshops. During long-term operation, whether it is the gasification heat exchanger in the gasification workshop or the ammonia-alcohol heat exchanger in the ammonia-alcohol workshop, tube leakage failures have occurred at different times and to different degrees, resulting in the temperature and flow rate of the cold seal water after heat exchange not meeting the design requirements, causing equipment damage due to the interruption of cold seal water for each user and triggering system shutdown accidents. Content of the Utility Model
[0003] The utility model provides a parallel system of cold seal water heat exchangers between a gasification workshop and an ammonia-alcohol workshop, effectively using the gasification heat exchanger in the gasification workshop and the ammonia-alcohol heat exchanger in the ammonia-alcohol workshop in parallel, avoiding the embarrassing situation of the shutdown of a certain section due to the lack of cold seal water for its users during the failure of a heat exchanger, thereby achieving the purpose of improving the long-term stable operation of the system.
[0004] The specific scheme is as follows:
[0005] A parallel system of cold seal water heat exchangers between a gasification workshop and an ammonia-alcohol workshop includes a hot seal water pipeline in the gasification workshop, which is connected to a gasification heat exchanger through valves A and B, and then connected to a gasification cold seal water user through valve C; it also includes a hot seal water pipeline in the ammonia-alcohol workshop, which is connected to an ammonia-alcohol heat exchanger through valves D, a lift pump, valves E, and G, and then connected to an ammonia-alcohol cold seal water user through valve H; a pipeline between valves A and B is connected between valves E and G through valve F; a pipeline between valve C and the gasification cold seal water user is connected between valve H and the ammonia-alcohol cold seal water user through valve I; the gasification heat exchanger and the ammonia-alcohol heat exchanger are respectively connected to a heat exchange circulating water pipeline.
[0006] Two parallel filter and regulation pipelines are arranged at the front end of the gasification cold seal water user; each filter and regulation pipeline includes a valve J, a filter, a regulating valve, and a valve K connected in sequence.
[0007] Pressure gauges are arranged at the front section of the gasification cold seal water user, the rear section of the gasification heat exchanger, and the rear section of valve I.
[0008] The utility model effectively uses the gasification heat exchanger in the gasification workshop and the ammonia-alcohol heat exchanger in the ammonia-alcohol workshop in parallel, avoiding the embarrassing situation that the users in a certain section have no cold seal water to use during the failure of a heat exchanger, resulting in the shutdown of the section, thereby achieving the purpose of improving the long-term stable operation of the system. Description of the Drawings
[0009] Figure 1 . Structural schematic diagram of the utility model. Detailed Implementation Modes
[0010] As Figure 1 shown,
[0011] A parallel system of cold seal water heat exchangers between the gasification workshop and the ammonia-alcohol workshop includes a hot seal water pipeline 12 in the gasification workshop, which is connected to the gasification heat exchanger 15 through valves A1 and B2, and then connected to the gasification cold seal water user 20 through valve C3; it also includes a hot seal water pipeline 13 in the ammonia-alcohol workshop, which is connected to the ammonia-alcohol heat exchanger 16 through valves D4, lift pump 14, valves E5 and G7, and then connected to the ammonia-alcohol cold seal water user 21 through valve H8; a pipeline between valves A1 and B2 is connected between valves E5 and G7 through valve F6; a pipeline between valve C3 and the gasification cold seal water user 20 is connected between valve H8 and the ammonia-alcohol cold seal water user 21 through valve I9; the gasification heat exchanger 15 and the ammonia-alcohol heat exchanger 16 are respectively connected to the heat exchange circulating water pipeline 16.
[0012] Two parallel filter and regulation pipelines are arranged at the front end of the gasification cold seal water user 20; each filter and regulation pipeline includes a valve J10, a filter 17, a regulating valve 18, and a valve K11 connected in sequence.
[0013] Pressure gauges 19 are arranged at the front section of the gasification cold seal water user 20, the rear section of the gasification heat exchanger 15, and the rear section of valve I9.
[0014] Normal state: Open valves A1, B2, and C3, close valves F6 and I9, open valves D4, E5, G7, and H8. The hot seal water in the gasification workshop normally passes through the gasification heat exchanger 15 for heat exchange, and then through the filter and regulation pipeline to the gasification cold seal water user 20. The hot seal water in the ammonia-alcohol workshop normally passes through the lift pump 14 and through the ammonia-alcohol heat exchanger 16 for heat exchange to the ammonia-alcohol cold seal water user 21;
[0015] When the gasification heat exchanger 15 in the gasification workshop is damaged, close valves B2 and C3, open valves A1, F6, D4, E5, G7, H8, and I9. The hot seal water in the gasification workshop and the hot seal water in the ammonia-alcohol workshop both pass through the ammonia-alcohol heat exchanger 16 for heat exchange to the gasification cold seal water user 20 and the ammonia-alcohol cold seal water user 21; at this time, the gasification heat exchanger 15 can be repaired.
[0016] When the ammonia-alcohol heat exchanger 16 in the ammonia-alcohol workshop is damaged, close valve G7 and valve H8, and open valve A1, valve B2, valve C3, valve D4, valve E5, valve F6, and valve I9. The hot seal water in the gasification workshop and the hot seal water in the ammonia-alcohol workshop are both heat-exchanged through the gasification heat exchanger 15 to the gasification cold seal water user 20 and the ammonia-alcohol cold seal water user 21; at this time, the ammonia-alcohol heat exchanger 16 can be repaired.
[0017] The above are only some preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
