Description

Technical Field

[0001] This utility model relates to the field of modern chemical technology, and in particular to a power generation device for a washing process. Background Technology

[0002] Modern chemical engineering, an industry closely related to our daily lives, is not limited to the production of basic chemicals but also extends to the application of fine chemicals and the research and development of new materials. In the modern chemical industry, the washing process is a ubiquitous step, playing a crucial role in ensuring product quality and safety.

[0003] In the washing process, large pressure and position differences are often encountered, which makes it difficult to effectively recover potential energy. In some washing process designs, although kinetic energy is recovered and utilized, the lack of regulating valves makes it impossible to meet the peak-shaving needs during production. In other designs, although regulating valves are installed, turbine generators are not equipped, which means that excess potential energy cannot be recovered and utilized, resulting in energy waste. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0005] Therefore, one objective of this utility model is to propose a power generation device for the washing process, which realizes the function of regulating production fluctuations and meets the needs of potential energy recovery and power generation, effectively solving the balance problem between production regulation and potential energy recovery.

[0006] To achieve the above objectives, the first aspect of this utility model proposes a power generation device for a washing process, comprising: a washing tower, a first valve, a synthesis gas-rich methanol cooler, a tower bottom heat exchanger, a purified gas-rich methanol heat exchanger, a sulfur-free methanol-ammonia cooler, a carbon dioxide-containing sulfur-rich methanol heat exchanger, a sulfur-containing methanol-ammonia cooler, a medium-pressure flash tower, a sulfur-free rich methanol pipeline, a sulfur-containing rich methanol pipeline, a first turbine generator, a second turbine generator, a second valve, and a third valve, wherein the washing tower is connected to the sulfur-free rich methanol pipeline.

[0007] In addition, the washing process power generation device proposed above according to this utility model may also have the following additional technical features:

[0008] Specifically, the sulfur-free methanol-rich pipeline is connected to the medium-pressure flash distillation tower after passing through the bottom heat exchanger, the purified gas-rich methanol heat exchanger, the sulfur-free methanol ammonia cooler, and the second valve.

[0009] Specifically, the bottom of the scrubbing tower is connected to a sulfur-rich methanol pipeline.

[0010] Specifically, the sulfur-rich methanol pipeline is connected to the medium-pressure flash distillation tower after passing through the bottom heat exchanger, the carbon dioxide sulfur-rich methanol heat exchanger, the sulfur-rich methanol ammonia cooler, and the third valve.

[0011] Specifically, the inlet of the first turbine generator is connected to the sulfur-free methanol-rich pipeline before the second valve, and the outlet of the first turbine generator is connected to the sulfur-free methanol-rich pipeline after the second valve.

[0012] Specifically, the inlet of the second turbine generator is connected to the sulfur-rich methanol pipeline before the third valve, and the outlet of the second turbine generator is connected to the sulfur-rich methanol pipeline after the third valve.

[0013] Specifically, the sulfur-free methanol-rich pipeline is connected to the bottom of the scrubbing tower after passing through the syngas methanol-rich cooler and the first valve.

[0014] Compared with the prior art, this utility model has the following beneficial effects: by coexisting with the turbine generator through the synergistic effect between multiple valves, when the flow regulation of the turbine generator can meet the production demand, these generators are used for power generation first. If the production fluctuates and the turbine generator is difficult to shaving, the regulation of production fluctuations is achieved by adjusting multiple valves during peak and off-peak periods, and the demand for potential energy recovery power generation is also met, effectively solving the balance problem between production regulation and potential energy recovery.

[0025] The washing tower 1 is connected to the sulfur-free methanol-rich pipeline 10.

[0026] Understandably, scrubbing tower 1 is used to treat industrial waste gas.

[0027] The sulfur-free methanol-rich pipeline 10 is connected to the medium-pressure flash tower 9 after passing through the bottom heat exchanger 4, the purified gas-rich methanol heat exchanger 5, the sulfur-free methanol ammonia cooler 6, and the second valve 14.

[0028] Understandably, the purified gas methanol-rich heat exchanger 5 can convert the heat generated during the outflow.

[0029] The bottom of the scrubbing tower 1 is connected to the sulfur-rich methanol pipeline 11.

[0030] Understandably, the sulfur-rich methanol pipeline 11 can filter the liquid flowing out of the washing tower 1.

[0031] The sulfur-rich methanol pipeline 11 is connected to the medium-pressure flash tower 9 after passing through the bottom heat exchanger 4, the carbon dioxide sulfur-rich methanol heat exchanger 7, the sulfur-rich methanol ammonia cooler 8, and the third valve 15.

[0032] The inlet of the first turbine generator 12 is connected to the sulfur-free methanol-rich pipeline 10 before the second valve 14, and the outlet of the first turbine generator 12 is connected to the sulfur-free methanol-rich pipeline 10 after the second valve 14.

[0033] Understandably, the sulfur-free methanol-rich pipeline can transport the filtered fluid back to the bottom of scrubbing tower 1.

[0034] The inlet of the second turbine generator 13 is connected to the sulfur-rich methanol pipeline 11 before the third valve 15, and the outlet of the second turbine generator 13 is connected to the sulfur-rich methanol pipeline 11 after the third valve 15.

[0035] Understandably, the first turbine generator 12 is able to convert the energy generated during fluid flow into electrical energy.

[0036] The sulfur-free methanol-rich pipeline 10 is connected to the bottom of the washing tower 1 after passing through the synthesis gas methanol-rich cooler 3 and the first valve 2.

[0037] It should be noted that the washing tower 1 described in this embodiment is divided into four parts from bottom to top: A, B, C, and D. The sulfur-free methanol-rich pipeline 10 is connected to section B of the washing tower 1, the sulfur-containing methanol-rich pipeline 11 is connected to section A of the washing tower 1, and the sulfur-free methanol-rich pipeline 10 is also connected to section A of the washing tower 1.

When the flow regulation of the turbine generator can meet production needs, these generators are used for power generation first. If production fluctuates and the turbine generator is difficult to shaving, the adjustment of multiple valves during peak and off-peak periods achieves the function of regulating production fluctuations and meets the needs of potential energy recovery for power generation, effectively solving the balance problem between production regulation and potential energy recovery.
