Description
Technical Field
The invention relates to an absorption heat pump driving steam recovery device of a power station waste heat utilization system, which can effectively solve the problem that the driving steam flow is not matched with a driving steam desuperheater at the initial starting stage of an absorption heat pump, effectively avoid water impact risks and improve the heat economy of a unit.
Background
With the increasing of urban buildings, a centralized heating network is needed to supply heat for more buildings, but the heat source of the city is seriously insufficient, and the newly added heat source brings environmental problems and is strictly controlled by environmental protection departments in various regions. The heat power plant circulating water waste heat recovery heat supply can realize the high-efficiency utilization and the cyclic utilization of energy, accords with the national energy-saving and emission-reducing political policy, and is also favorable for relieving the contradiction of the urban heating and heat supply energy. The thermal power plant has abundant waste heat resources, only about 33% of heat energy after fuel combustion is converted into electric energy for utilization, most of heat energy is discharged into the environment through channels such as boiler flue gas and condenser circulating water, taking a cogeneration system as an example, the heat taken away by the condenser circulating water under a rated heating working condition accounts for about 24% of the total heating amount of the fuel and accounts for more than 65% of the external heat supply amount of a unit, an absorption heat pump technology is from the United states, the technology is developed in Japan, and the current small and modular heat pump products are proved to be a mature technology in the fields of civil use, including steel, coal, oil fields, chemical industry and the like, and the application is wide.
The technical development is applied to the recycling of low-value heat energy of circulating water of a power plant, and is theoretically feasible. However, the application of the absorption heat pump in the power plant is not the increase and decrease of a plurality of simple equipments, which has a great influence on the steam and water flows of the circulating water system, the heat supply network water system, the heat recovery system and even the steam turbine of the power plant, and compared with the large-scale equipment of the power plant, the heat pump belongs to the micro-equipment, so that the power plant actively adapts to or caters to the operation parameters of the heat pump, and the optimal working condition of the heat pump operation is not practical. Particularly for a large-scale heat supply unit, the technical integration degree between main equipment and auxiliary equipment of the steam turbine is higher, the borne power generation and regional heat supply tasks are harder, the reliability requirement on the application of a new technology is higher, and therefore the application of the new technology of the heat pump is treated more cautiously. In addition, the one-time investment of the absorption heat pump is too high, the investment risk factor of the power plant has to be considered, and the popularization and application of the energy-saving technology in the aspect of recycling the circulating water low-value heat energy of the power plant are also influenced to a certain extent. The compression heat pump adopts electric power as driving energy, mainly comprises evaporimeter, compressor and condenser triplex, through letting working medium constantly accomplish evaporation (absorb the condensation heat in the circulating water) → compression → condensation (release heat and transfer to the heat supply network circulating water) → throttle → the thermodynamic cycle process of reevaporation to transfer the condensation heat in the circulating water to the heat supply network circulating water.
The Chinese patent discloses an absorption-reabsorption-generation system and a first-class absorption heat pump (with the publication number of CN 101957093A), which have the following disadvantages: although the whole system can complete the circulation of the absorption-reabsorption generation system and the first-class absorption heat pump when in work, the absorption heat pump requires driving steam to be saturated steam when in initial start (a steam turbine supplies heat and extracts steam to be superheated steam, the superheat degree is about 90-140 ℃, because the convection heat transfer coefficient of the superheated steam is far lower than that of the saturated steam, compared with the use of the saturated steam, the equipment volume required by heat exchange is larger and more expensive, so a desuperheater is generally required to be installed to desuperheat the superheated steam before entering the heat pump to be saturated, when the superheat degree of the steam is increased, the larger the heat transfer area for sensible heat exchange is, the poorer the overall heat exchange effect is, the poorer the heat exchange effect can cause the concentration of solution in the generator to be reduced, the absorption capacity of the solution to be reduced, and the refrigeration capacity to be reduced), and the steam provided by the steam turbine is superheated steam, the superheated steam before entering the heat pump is cooled to a saturated state. In actual engineering, desuperheaters are designed according to rated steam flow, and in the initial starting stage of a heat pump system, a steam regulating valve at the inlet of a heat pump needs to be opened slowly, so that the system cannot achieve the steam flow, the steam flow required in the initial starting stage is only about 5% of the rated steam flow, and mismatching between the desuperheaters and the steam flow is caused (at least 25% of the rated steam flow is required to ensure normal operation of the desuperheaters). When the desuperheating water is put into the boiler, only a small amount of the desuperheating water sprayed by the desuperheating device is vaporized into steam and plays a role in reducing the temperature of driving steam, most of the desuperheating water cannot be vaporized, at the moment, two media of steam and water exist in a steam pipeline, water impact of the steam pipeline can happen at any time, and once the steam main pipe of the heat pump system is connected with the steam turbine and the heat network heater, the heat pump system is damaged by the water impact, and the safe and stable operation of the steam turbine and the heat network heater is threatened.
