Description

Technical Field

[0001] The utility model relates to the technical field of waste heat utilization of heat recovery coke ovens in coking production, in particular to a condensate water regulation system for waste heat power generation of coke dry quenching supporting a heat recovery coke oven. Background Technique

[0002] Green economy and circular economy are the development directions of future production enterprise management. Energy conservation and environmental protection are the two major issues that the metallurgical industry must face at present. The waste heat utilization technology of heat recovery coke ovens has many advantages such as energy recovery and utilization and environmental protection, and is thus promoted in the coking industry. At present, the waste heat utilization technology of conventional heat recovery coke ovens at home and abroad is becoming increasingly mature. This technology has been widely applied in China and has achieved remarkable economic and social benefits.

[0003] The flue gas temperature of the heat recovery coke oven can reach 1200°C to 1300°C. It is sent to the heat recovery boiler through a high-temperature flue gas pipeline for heat exchange, heating the boiler feed water to make it undergo a phase change and rise in temperature to become superheated steam, which is then sent to a steam turbine power station for power generation. On the other hand, the red-hot coke produced by the heat recovery coke oven needs to be sent into the coke dry quenching furnace for cooling by an inert circulating gas (the main component is nitrogen). After the inert circulating gas exchanges heat, its temperature rises to about 960°C and enters the coke dry quenching boiler for heat exchange, heating the boiler feed water to make it undergo a phase change and rise in temperature to become superheated steam, which is then sent to a steam turbine power station for power generation. The superheated steam forms exhaust steam after doing work and generating electricity. The exhaust steam is introduced into a condenser at the tail of the steam turbine and is cooled by cooling water to form condensate water. The condensate water returns to the boiler feed water system again as boiler make-up water to complete the steam-water cycle.

[0004] From the above description, it can be seen that the condensate water of the waste heat power generation process of the coke dry quenching supporting the heat recovery coke oven needs to be separately returned to the feed water systems of the heat recovery coke oven waste heat boiler and the coke dry quenching boiler. For the distribution of the condensate water flow of the two boiler feed water systems, it needs to be determined according to the process characteristics of the heat recovery coke oven waste heat boiler and the coke dry quenching boiler, and corresponding adjustment measures need to be set to achieve it. Therefore, it is necessary to develop a condensate water regulation system that can not only meet the requirements of condensate water reuse of the heat recovery boiler and the coke dry quenching boiler, with reasonable distribution of condensate water in the two systems, but also ensure the safe and stable water supply of each system.

[0029] Working process:

[0030] 1) After exhaust steam of the steam turbine generator set is condensed in the condenser, it forms condensate and enters the condenser hot well 1 of the steam turbine generator set, and is sent out by the condensate pump 2 under pressure. The condensate passes through the condensate pump 2 and the steam seal heater 3 for heat exchange and then enters the heat recovery boiler feed water condensate mother pipe 16, and is sent to the heat recovery boiler feed water medium-pressure deaerator 4 through the heat recovery boiler medium-pressure deaerator condensate inlet regulating valve 11, and is merged into the desalted water replenishment mother pipe 17 through the heat recovery boiler medium-pressure deaerator desalted water replenishment electric valve 12, and enters the dry quenching boiler feed water desalted water tank 5 through the adjustment valve 2; the condensate inlet pipe of the dry quenching boiler feed water desalted water tank 5 passes through the dry quenching boiler desalted water tank condensate inlet regulating valve 14, and the dry quenching boiler feed water condensate regulating valve 10 is connected to the condensate inlet pipe of the dry quenching boiler feed water desalted water tank 5;

[0031] 2) The frequency converter performs frequency conversion speed regulation on the condensate pump 2 according to the hot well level gauge 6 of the steam turbine generator set, and the outlet flow of the condensate pump 2 is adjusted within the set range, so that the liquid level of the water in the hot well 1 of the condenser of the steam turbine generator set is maintained within the set range, ensuring that the exhaust steam of the steam turbine can be smoothly condensed and sent out after being exhausted;

[0032] 3) The CDQ boiler feed water condensate regulating valve 10 is adjusted according to the turbine generator set condensate pipeline pressure transmitter 7, so that the pressure of the output main pipeline of the condensate pump 2 is adjusted within the set range; the CDQ boiler feed water condensate regulating valve 10 first ensures that the outlet pipeline of the condensate pump of a single turbine generator set has sufficient pressure to send the condensate to the heat recovery boiler feed water medium pressure deaerator 4, and the excess condensate will be sent to the CDQ boiler feed water desalted water tank 5 through the CDQ boiler feed water condensate regulating valve 10;

[0033] 4) The condensate inlet regulating valve 11 of the heat recovery boiler medium-pressure deaerator is adjusted according to the medium-pressure deaerator water level gauge 8 of the heat recovery boiler feed water, so that the liquid level of the heat recovery boiler feed water medium-pressure deaerator 4 is maintained within the set range.

[0034] 5) The condensate water inlet regulating valve 14 of the CDQ boiler desalted water tank is adjusted according to the CDQ boiler feed water desalted water tank level gauge 9, so that the liquid level of the CDQ boiler feed water desalted water tank 5 is maintained within the set range;

[0035] 6) The desalted water replenishment electric valve 12 of the heat recovery boiler medium-pressure deaerator is interlocked with the heat recovery boiler feed water medium-pressure deaerator water tank liquid level gauge 8. If the liquid level of the heat recovery boiler feed water medium-pressure deaerator 4 reaches the minimum limit setting value, the heat recovery boiler medium-pressure deaerator desalted water replenishment electric valve 12 opens, and the desalted water enters the water tank of the heat recovery boiler feed water medium-pressure deaerator 4 to prevent the liquid level from being too low and the subsequent water supply from being insufficient;

[0036] 7) The CDQ boiler desalted water tank water replenishment electric valve 13 is interlocked with the CDQ boiler feed water desalted water tank level gauge 9. When the liquid level of several quenching boiler feed water desalted water tanks 5 reaches the lowest limit setting value, the CDQ boiler desalted water tank water replenishment electric valve 13 is opened, and the desalted water enters the quenching boiler feed water desalted water tank to prevent the liquid level from being too low and the subsequent water supply from being insufficient. According to the different characteristics of the condensate destination, different adjustment mechanisms (including condensate pump frequency conversion adjustment and each regulating valve adjustment) are set. Under the condition of the balance of the hot well liquid level of the steam turbine generator set condenser, the water inlet pressure of the heat recovery boiler feed water medium pressure deaerator is guaranteed first. The water inlet pressure is obtained by the steam turbine generator set condensate pipeline pressure transmitter to ensure that the heat recovery boiler feed water medium pressure deaerator receives enough condensate, and the rest of the condensate is sent to the CDQ boiler feed water desalted water tank. Through the above mechanism, the condensate distribution of the condensate regulating units of the two steam turbine generator sets is guaranteed to be reasonable, and the water supply of each steam turbine generator set condensate regulating unit is safe and stable.
