Problems solved by technology

However, the introduction of the heat pump system brings difficulties in cleaning the rubber balls of the condenser, or the temperature of the circulating water at the inlet of the heat pump is far lower than the design value due to the cold water from the pool entering the system, which affects the performance of the heat pump and even fails to operate normally.

Embodiment 1

[0046] Embodiment 1: thermal power plant circulating water system

[0047] The circulating water system of the thermal power plant consists of the first unit and the second unit.

[0048] The circulating water system of the thermal power plant consists of the following:

[0049] The first unit consists of the first cooling tower 1, the first circulating water pump 4, the first condenser 8, the ice breaking pipeline valve 2, the circulating water return water main pipe valve 3, the circulating water pipeline valve 25 and the circulating water supply main pipe valve 28 Composition, the first cooling tower 1 is connected with the first condenser 8 through the first circulating water pump 4, the circulating water supply main pipe valve 28 and the circulating water supply main pipe 5, and the first condenser 8 is returned to the jellyfish through the circulating water The pipe 6 and the circulating water return jelly pipe valve 3 are connected to the first cooling tower 1, and the...

Embodiment 2

[0055] Embodiment 2: thermal power plant circulating water system

[0056] The circulating water system of the thermal power plant consists of the first unit and the second unit.

[0057] The circulating water system of the thermal power plant consists of the following:

[0058] The first unit consists of the first cooling tower 1, the first circulating water pump 4, the first condenser 8, the ice breaking pipeline valve 2, the circulating water return water main pipe valve 3, the circulating water pipeline valve 25 and the circulating water supply main pipe valve 28 Composition, the first cooling tower 1 is connected with the first condenser 8 through the first circulating water pump 4, the circulating water supply main pipe valve 28 and the circulating water supply main pipe 5, and the first condenser 8 is returned to the jellyfish through the circulating water The pipe 6 and the circulating water return jelly pipe valve 3 are connected to the first cooling tower 1, and the...

Embodiment 3

[0064] Embodiment 3: the use of the circulating water system of thermal power plant of the present invention

[0065] The implementation steps of this embodiment are as follows:

[0066] The thermal power plant circulating water system used in this embodiment is as attached figure 1 shown. The circulating water of the first unit comes out of the first cooling tower 1 and is boosted by the first circulating water pump 4, then enters the water side space of the first condenser 8 along the circulating water supply main pipe 5 to be heated, and then returns to the jellyfish along the circulating water The pipe 6 rises to the packing layer of the first cooling tower 1 through the valve 3 of the circulating water return jellyfish pipe, and its circulating water is cooled by the ambient air during the process of naturally falling into the storage tank, and then enters the first circulating water pump 4, and so on. ;

[0067] The circulating water of the second unit comes out of th...

Abstract

The invention relates to a thermal power plant circulating water system with a function of recycling waste heat. The thermal power plant circulating water system comprises a first unit and a second unit. The first unit comprises a first cooling tower 1, a first circulating water pump 4, a first condenser 8, an icebreaking pipeline valve 2, a circulating water return water main pipe valve 3, circulating water pipeline valve 25 and circulating water supplying main pipe valve 28. The second unit comprises a second cooling tower 11, a second circulating water pump 14, a second condenser 18, a second icebreaking pipeline valve 12, a second circulating water return water main pipe first valve 13 and second circulating water return water main pipe second valve 29. The thermal power plant circulating water system has the advantages of being simple in structure, flexible and convenient to adjust, good in anti-freezing effect, energy-saving and electricity-saving, thoroughly solves the problems of safe and stable operation of the existing thermal power plant circulating water system and freezing of the cooling towers and pools.

Description

【Technical field】 [0001] The invention belongs to the technical field of power generation equipment cooling. More specifically, the present invention relates to a thermal power plant circulating water system with waste heat recovery function. 【Background technique】 [0002] With the implementation of the national policy of "energy saving and emission reduction" and thermal power units "upgrading large and reducing small" thermal power plants, urban central heating with thermal power plants equipped with large-capacity extraction and condensing units with good economy and strong load adaptability as heat sources The system is becoming more and more common in my country's "Three North" regions. In recent years, it has become an irreversible trend for thermal power plants to use absorption heat pumps to recover waste heat from circulating water and realize energy saving and efficiency enhancement. However, problems such as freezing of cooling towers, performance assurance of h...
