Embodiment Construction

[0056] For better illustrating the present invention, facilitate understanding technical scheme of the present invention, typical but non-limiting embodiment of the present invention is as follows:

[0057] A cooling tower water vapor and heat energy recovery method, the method introduces the water vapor discharged from the cooling tower 1 into the condenser 2; in the condenser 2, the condensing agent water is atomized into fine particles, sprayed on the water vapor, and the water vapor Condensed into water when condensed, the air is discharged from the condenser 2 in a dry and hot state.

[0058] The condensed water formed in the condenser 2 transfers its heat energy to the dry hot air discharged from the condenser 2 through heat exchange; or, preheats other gases or liquids that need to be heated.

[0059] The thermal energy of the hot and dry air discharged from the condenser 2 is recovered to form dry and cold air for discharge or return to the cooling tower 1 for air inta...

Abstract

The invention discloses a cooling tower water vapor and heat energy recovery method and system. The method comprises the steps that water vapor exhausted by a cooling tower is introduced into a condenser; in the condenser, water atomization is carried out on a condensing agent to form fine particles which are sprinkled on the water vapor, and the water vapor is condensed into water by meeting the cold; air in the dry heat state is exhausted from the condenser. The system comprises the cooling tower and the condenser. An outlet of an air cylinder at the top of the cooling tower is connected with a water vapor inlet of the condenser. In the condenser, a condensing agent ejector is arranged above the water vapor inlet. According to the cooling tower water vapor and heat energy recovery method and system, the water evaporation loss of the cooling tower can be effectively reduced, the energy which should be abandoned by the system can also be recovered and cooled, and the zero release of the cooling tower of a circulating water system is basically achieved. By the adoption of the system, only appropriate adjustment is required for an existing cooling tower, the condenser and a heat pipe exchanger are additionally arranged, the most economical cooling water spray is used as the condensing agent, and an efficient heat pipe is used for recycling heat energy.

Description

technical field [0001] The invention relates to the technical field of water saving, energy saving and zero discharge of industrial circulating water cooling towers, in particular to a method for recovering water vapor and heat energy of a wet cooling tower and a zero discharge system. Background technique [0002] Cooling towers are divided into wet type and dry type according to the contact mode of water and air. The wet type means direct contact between water and air, which has high heat exchange efficiency and large water loss; the dry type means indirect contact between water and air without water loss, but its heat exchange efficiency is low, energy consumption is high, and investment is large. [0003] The wet cooling tower is an important heat and mass transfer equipment in the fields of energy, power and chemical industry. Its function is to discharge the waste heat of the production process, and to reduce the temperature of the circulating cooling water reduce. T...
