Novel pipe housing type automatic liquid separating condenser

Abstract

The invention discloses a novel pipe housing type automatic liquid separating condenser. The novel pipe housing type automatic liquid separating condenser includes a pipe and two pipe boxes which are arranged two ends of the pipe respectively; pipe bundles and baffle plates are arranged in the pipe; automatic liquid separating devices are arranged in the pipe boxes; the automatic liquid separating devices include partition plates having grooves and automatic discharging valves; discharging holes are formed in the bottom ends of the grooves; the automatic discharging valves are arranged on the discharging holes; and the automatic discharging valves are connected to automatic reset mechanisms. The advantages and the beneficial effects of the invention are that the heat transferring flow performance of gas is improved while the gas is condensed in the pipe, and a condensate liquid can be timely separated through the automatic discharging devices; the dry degree of condensate steam is improved; the pressure can be effectively reduced, and the heat transfer coefficient of the pipe can be effectively improved; the number of the pipes can be effectively reduced, the cost is reduced, and the heat exchange area is decreased by more than 20%.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of condensers, in particular to a novel shell-and-tube type automatic liquid separation condenser. [0003] 【Background technique】 [0004] In industrial production, such as in chemical plants, there are often high-pressure, corrosive and toxic vapors that need to be cooled. At the same time, it is used in the refrigeration industry or in equipment that uses refrigerants, such as the organic Rankine cycle system for low-temperature waste heat power generation. In order to reduce the amount of refrigerant charged, reduce the cost of the system, facilitate the maintenance of the heat exchanger and prevent the leakage of toxic substances, it is necessary to adopt the method of steam flowing in the pipe and cooling water flowing in the shell. However, the traditional shell-and-tube condenser currently used has the following problems: during the condensation process of the steam in the heat exchange tube, its liqu...

Problems solved by technology

However, the traditional shell-and-tube condenser currently used has the following problems: during the condensation process of the steam in the heat exchange tube, its liquid film will gradually increase, and the thermal resistance will gradually increase, which will lead to the deterioration of the subsequent condensation heat transfer effect; and in During the condensation process, as the steam condenses, the dryness of the steam will decrease, the condensation rate of the steam in the heat exchange tube will degrade sharply, and the heat transfer coefficient will become smaller; at the same time, the traditional shell-and-tube heat exchanger does not take liquid separation measures , along the flow direction of the tube side, the dryness of the steam gradually decreases, the condensate and the steam flow together, and only the vapor phase participates in the heat exchange. Compared with the high dryness part of the initial tube side, the utilization efficiency of the tube is reduced due to the decrease in the dryness of the later tube side , the role of the pipe is not fully utilized
