A one-way blocking condensate fluid dripping backflow drawing device

Abstract

The invention discloses a one-way blocking type condensed fluid dripping, reflux and guide-out device. The one-way blocking type condensed fluid dripping, reflux and guide-out device comprises a condensation reflux assembly and a metal hoarding for sealing the condensation reflux assembly, wherein the condensation reflux assembly comprises a metal bottom plate which is densely covered with punched holes, fluid channel tubes which are welded with punched hole sites, metal plate shells covering the tops of the fluid channel tubes, a metal net fixed to the metal plate shells, and a discharge pipeline used for discharging a condensed fluid. The one-way blocking type condensed fluid dripping, reflux and guide-out device is suitable for chemical rectification equipment and a condensed type heat exchanger; high-temperature gas is condensed by the heat exchanger to form the condensed fluid; and the condensed fluid drops under the action of the gravity, passes through the metal net to drop onto the metal plate shells, drops onto the metal bottom plate along the metal plate shells, and is finally discharged through the discharge pipeline. The one-way blocking type condensed fluid dripping, reflux and guide-out device is reliable and practical in structure, is capable of effectively refluxing and guiding out the condensed fluid in the heat exchanger and is beneficial for saving energy resources and reducing environmental pollution.

Description

technical field [0001] The invention relates to the technical field of condensation of heat exchangers, and more specifically relates to a one-way blocking condensate fluid dripping backflow drawing device suitable for chemical distillation equipment and condensation heat exchangers.

Problems solved by technology

[0002] At present, in the domestic and international markets, the main auxiliary equipment of the rectification unit in the chemical industry includes chemical process equipment such as steam condensing heat exchangers, product condensing heat exchangers, and tower bottom reboiling heat exchangers, as well as domestic condensing equipment with natural gas as the main fuel. Gas-fired water heaters, condensing gas-fired heating bath boilers and other household heating appliances have the process of gravity back-mixing or gravity reflux of condensed liquids to meet the technical requirements of product distillation or waste discharge; but in natural gas as the main Fuel household condensing gas water heaters, condensing gas heating bath boilers and other household heating equipment design and manufacturing industries, because the high-temperature waste gas after combustion contains a large amount of water vapor, after secondary heat exchange, the high-temperature The nitrogen oxides, carbon dioxide and sulfur dioxide or sulfur trioxide in the exhaust gas are easily dissolved in the condensed water to form a highly corrosive acidic aqueous solution. If it is allowed to drip down, it will not only cause corrosion and leakage of the bottom heat exchanger More seriously, it will directly drop on the flame, resulting in incomplete combustion to produce carbon monoxide, which will cause serious harm to the home; or the product after rectification in the chemical industry will be back mixed and deteriorated to cause losses. Therefore, it is urgent for the industry to solve such technical problems
