Embodiment 1

[0027] The fully enclosed circulating water system of the present invention utilizing the air cooler to recover the latent heat of the condensing unit is as follows: figure 1 As shown, it includes a steam turbine 1 and a boiler 5 used in conjunction with the steam turbine 1, the steam exhaust outlet of the steam turbine 1 is connected with a condenser 2, and also includes a water collecting pipe 4 containing the treated circulating medium, a circulating water pump 3, an air cooling 8 and the water distribution pipe 6, the circulating water outlet of the condenser 2 is connected with the water inlet of the water collecting pipe 4, and the water outlet of the water collecting pipe 4 is connected with the water inlet of the circulating water pump 3. The water outlet is connected with the water inlet of the air cooler 8, the water outlet of the air cooler 8 is connected with the water inlet of the water distribution pipe 6, and the water outlet of the water distribution pipe 6 is c...

Embodiment 2

[0041] like figure 2 As shown, the difference between this embodiment and the first embodiment is that this embodiment further includes a refrigerator 10, and the refrigerator 10 includes a condenser 11 and an evaporator 12, and the condenser 11 is disposed in the air cooler 8 Between the circulating water pump 3 , the evaporator 12 is arranged between the air cooler 8 and the water distribution pipe 6 .

[0042] When the summer is hot, the setting of the refrigerator 10 is conducive to further cooling the circulating medium, so that the vacuum in the condenser 2 can be kept in the most economical state, and the condenser 11 and the evaporator 12 of the refrigerator 10 are arranged in the air cooling. On both sides of the condenser 8, when the temperature of the water flowing through the air cooler 8 does not meet the needs of the condensing unit, the refrigerator 10 will be activated. The supply air is exchanged in the device 8. The condenser 11 and evaporator 12 of the re...

Abstract

The present invention relates to the technical field of heat treatment systems, in particular to a fully enclosed circulating water system that utilizes an air cooler to recover the latent heat of a condensing unit, including a steam turbine and a boiler, and the steam turbine is connected to the condenser, and also includes a water collection pipe containing a treated circulating medium, Circulating water pump, air cooler and water distribution pipe, the circulating water outlet of the condenser is connected with the water inlet of the water collection pipe, the water outlet of the water collection pipe is connected with the water inlet of the circulating water pump, and the water outlet of the circulating water pump is connected with the water inlet of the air cooler , the water outlet of the air cooler is connected to the water inlet of the water distribution pipe, the water outlet of the water distribution pipe is connected to the circulating water inlet of the condenser, and the air cooler is connected to the boiler through the blower; the processed circulating medium is used instead of industrial water, water quality Pure, good heat exchange effect, the air blower is connected with the air cooler to increase the temperature of the air supply, heat the air needed for boiler combustion, effectively reduce fuel consumption, and has the characteristics of low construction cost, energy saving and less environmental pollution.

Description

technical field [0001] The invention relates to the technical field of heat treatment systems, in particular to a fully enclosed circulating water system that utilizes an air cooler to recover the latent heat of a condensing unit. Background technique [0002] With the development of society, the continuous improvement of people's living standards, the continuous increase of city scale, the energy consumption is also increasing. In order to sustain development, the country is paying more and more attention to energy conservation and emission reduction. [0003] Electricity is an indispensable high-level energy in today's society. The existing condensing steam units of thermal power plants use surface condensers, and the condensed steam adopts closed or open circulating water systems. At present, due to environmental protection requirements, the newly installed units basically adopt a closed circulating water system, that is, the circulating water passes through the cooling ...
