Technical Field

The invention relates to a heat pipe heat storage combined type water cooling method and a device thereof, in particular to a heat pipe circulating water cooling method and a heat storage type circulating water cooling method combined type circulating water cooling method and a device thereof, belonging to the technical field of water saving.

Background

In modern industry, a plurality of mechanical motion heat generation needs cooling, some process media and process product discharge devices need to reach a certain low temperature to ensure product safety, cooling is needed, some intermediate processes need cooling, a civil air-conditioning cooling system, industrial refrigeration series, injection molding, leather making, foaming, power generation, a steam turbine, aluminum profile processing, an air compressor, electric power, metallurgy, chemical engineering, petroleum and petrochemical industry, coal chemical engineering and the like all need cooling water, the cooling water is recycled and is also called as circulating water, with the improvement of energy conservation and emission reduction technical means, the cooling waste heat which can be utilized in any process is applied, the residual heat can be taken away by the circulating water if the heat can not be utilized any more, the circulating water is recycled after being cooled in a cooling water tower through a circulating water pipeline system, at present, the cooling water tower is basically open, and the principle of the cooling water tower (also called as a cooling water tower) is that water is atomized into micro water droplets to be, some also need to add fillers to increase the contact area with the air, to dissipate the waste heat of the circulating water by the water evaporation process, after the dry low enthalpy air is pumped by the fan, or a high tower form can be adopted, the water enters the cooling tower from the air inlet by utilizing the chimney effect, the water with the damp heat and the high enthalpy is sprayed into the tower from the water-spreading system, when the water drops contact with the air, on one hand, because the heat transfer coefficient of the air is lower, and on the other hand, because the pressure difference exists between the surface of the water vapor and the air, the high-temperature water molecules with large saturated vapor partial pressure flow to the air with low pressure, the evaporation phenomenon is generated under the action of pressure, air and atomized water vapor are discharged from the top by the chimney effect of a fan or a cooling water tower, evaporation latent heat is taken away, heat in water is taken away, namely evaporation heat transfer is carried out, evaporated water is also taken away, and therefore the purpose of cooling is achieved, and the evaporated water is lost. The device achieving the function is a cooling water tower, the cooling tower is various in types, the cooling tower is distinguished according to the structure of the tower and the air flowing condition, two categories of natural draft cooling towers and mechanical draft cooling towers are provided, the cooling effect of the mechanical draft cooling towers is best, and the circulation ratio is generally 3-5 times. The cooling water tower has the functions that cooling water carrying waste heat is atomized in the tower, fine liquid drops of the atomized water carry out mass transfer and heat transfer on the surface of a filler in the water cooling tower, evaporation phenomena are generated under the action of pressure due to the pressure difference between the surface of water vapor and air, evaporation latent heat is taken away along with the outflow of the air, heat in water is taken away, namely evaporation heat transfer is carried out, and partial materialized small liquid drops carry out heat exchange with the air, so that the waste heat is transmitted to the air and is dispersed into the atmosphere together with the evaporated water vapor. The water of 1KG of evaporation under the ordinary pressure needs 600 Kcal's latent heat of evaporation, namely evaporates one hundredth water, makes remaining water reduce the temperature of 6 ℃ of water, and it is thus obvious that circulating water cooling needs to consume a large amount of water, causes the water waste serious.

In addition, the open water tank and the cooling water tower are exposed in the atmospheric environment, when the atmosphere contains sand and dust, the open cooling water tower system can wash or absorb and dissolve the sand and dust contained in the atmosphere to cause the pollution of a circulating water system, the invasion of the sand and dust brings about the scaling problem of the circulating water system, the thermal resistance is increased due to scaling, the original heat exchange system is damaged, scaling and regular descaling are needed, and scaling prevention and descaling consumption is caused.

The open type water tank and the cooling water tower are used for circulating water to easily breed bacteria and algae in a low-temperature environment, chemical reagents are required to be added for sterilization and algae removal, and consumption of chemical additives is reduced.

With the serious atmospheric pollution, the acidic harmful substances in the atmosphere also carry out mass transfer in the atomization heat transfer process of water, so that the acidic gas in the atmosphere is dissolved into the water, the corrosivity of circulating water is increased, and the corrosion of a pipeline system and cooling equipment is caused.

Therefore, the current method for cooling water causes waste of water resources, and causes various problems of the structure, corrosiveness and breeding of bacteria and algae of circulating water.

A method for heat accumulating type cooling circulating water (application number: 201510200644.X) proposes a method for heat accumulating type cooling circulating water.
