Novel shell-and-tube evaporative condenser

Abstract

The utility model provides a novel shell and tube evaporative condenser which is characterized by comprising an atomizing device, a heat exchange device, a negative-pressure fan and a water and air separating device. A water inlet and a wind inlet are formed in a side of the atomizing device, the other side of the atomizing device is connected with the heat exchange device, the heat exchange device comprises a barrel, a tube plate and heat exchange copper tubes, an air inlet is formed in the upper side of the barrel, and a liquid outlet is formed in the lower side of the barrel. Water scales can be generated by the novel shell and tube evaporative condenser, common water scales are mostly generated on the inner walls of the copper tubes, the copper tubes are straight tubes, accordingly, the water scales can be treated by a chemical method or a physical method, and the treatment methods are simple and convenient. The novel shell and tube evaporative condenser has the advantages that the novel shell and tube evaporative condenser is simple in structure, small in size and low in power consumption, production cost and failure rate and reliable in running; the copper tubes are used as heat conduction materials, the heat conductivity coefficient of copper is 386W / mXoC, and water is sucked into the copper tubes after being atomized, and evaporates and absorbs heat in a negative-pressure state.

Description

[0001] technical field [0002] The invention relates to a condenser, in particular to a novel shell and tube evaporative condenser. Background technique [0003] A condenser is a device that can condense a gaseous substance into a liquid state. Generally, the substance is condensed by cooling. During the condensation process, the substance releases latent heat to increase the temperature of the refrigerant in the condenser. At present, the evaporative condensation technology that has been applied in our country has defects such as huge equipment, complex structure, low heat exchange efficiency, and inability to clean. Most of the existing condensers have an open water circulation system, including water pumps, water trays, water distributors, etc. During use, additional circulating water is required, which will not only increase the volume of the condenser, but also waste more water due to water circulation.

Problems solved by technology

At present, the evaporative condensation technology that has been applied in our country has defects such as huge equipment, complex structure, low heat transfer efficiency, and inability to clean.

Most of the existing condensers have an open water circulation system, including water pumps, water trays, water distributors, etc. During use, additional circulating water is required, which will not only increase the volume of the condenser, but also waste more water due to water circulation. There are many power resources, and the management of circulating water itself is very difficult, and it is prone to water leakage, overflow, water spray, flying water, etc. Since it is an open circulating water, it will definitely be polluted by air, and there will be A lot of cleaning and water changes have to be done. Today's condensers have no way to deal with the scale generated after water evaporation; the heat transfer materials used in the existing evaporative condensation technology are stainless steel plates, hot-dip galvanized plates, carbon Steel pipe and other materials, the thermal conductivity of these materials is between 40-50W / m℃, and the water is directly poured on the surface of the heat exchanger, and the air flow on the water surface is accelerated by the fan, so that the water evaporates and absorbs heat exchange the heat in the
