Abstract
The utility model discloses a deaerator with a variable-sound-velocity pressurizing heat exchanger, comprising a deaerator body (8), a water jet and air suction mechanism and a variable-sound-velocity pressurizing heat exchanger (6), wherein a steam inlet end of the variable-sound-velocity pressurizing heat exchanger is connected to a steam pipeline (1), a cold water inlet end is connected to a water supply pipeline (2), and a vapor/liquid outlet end is connected to an inlet end of the deaerator body (8). According to the deaerator disclosed by the utility model, since the variable-sound-velocity pressurizing heat exchanger is connected with the steam pipeline and the water supply pipe, supplied water is heated to a vacuum boiling point before entering the deaerator body, and then directly enters the deaerator body through the pipeline to be deoxidized directly without being heated with steam, thus solving a problem that the steam and the water are mixed unevenly and effectively improving deaeration efficiency.
Description
Technical field
The utility model belongs to deoxygenator technical field, particularly be the deoxygenator with acoustic velocity-variable supercharging heat exchanger.
Background technology.
At present, the application of deoxygenator in industry is very extensive, and its Main Function is except the oxygen in anhydrating, and guarantees the quality of feedwater.Once dissolve oxygen in water, will make the metallic corrosion contacting, if there is gas accumulation in heat exchanger, will hinder the carrying out of heat transfer process, reduce the heat-transfer effect of equipment.Therefore it is all disadvantageous in water, being dissolved with any gas, oxygen especially, and it will directly threaten the safe operation of equipment.When water contacts with certain gaseous mixture, will some gas dissolving in water.The solubleness of gas just means the quantity of gas dissolving in water, the kind of he and gas and it is relevant with the temperature of water at the pressure component of the water surface.Under certain pressure, the temperature of water is higher, and the solubleness of gas is just less; Otherwise the solubleness of gas is just larger.Gas is higher at the pressure component of the water surface simultaneously, and its solubleness is just larger, otherwise its solubleness is just lower.The effect of deoxygenator is that feedwater is heated to certain temperature, to reduce its oxygen level, thereby reach, prevents the object of dissolved oxygen to the corrosion of pipeline and equipment.Principle of work utilizes steam to heat water, makes water reach temperature of saturation---the boiling point under certain pressure.At this moment the space of deoxygenator water vapour abrim, and the pressure component of oxygen is reduced to zero gradually, the pressure component being dissolved in the water is reduced to zero, and the oxygen that is dissolved in water will all overflow, to guarantee the qualified of oxygen level of feeding water.
At present, what feedwater deaeration mode was the most frequently used is thermal de-aeration, and thermal de-aeration can be divided into three kinds of vacuum type, air suspended type and high voltage types.Air suspended type and high voltage type deoxygenation work water temperature are higher, conventionally more than 100 ℃, and adopt vacuum type deoxygenator work water temperature can be reduced to 45 ℃ of left and right, can greatly reduce the preheating requirement to water, save the energy.But in thermal de-aeration process, because steam directly mixes in deoxygenation head with feedwater, easily cause mixing inhomogeneous and affect deaerating effect.
Summary of the invention
In order to solve above technical deficiency, the purpose of this utility model is to propose a kind of deoxygenator with acoustic velocity-variable supercharging heat exchanger, solves steam and mixes inhomogeneous problem with water, improves oxygen removal efficiency.
The utility model is realized the technical scheme that above-mentioned purpose takes: a kind of deoxygenator with acoustic velocity-variable supercharging heat exchanger, comprise deoxygenator, jetting extraction sector and acoustic velocity-variable supercharging heat exchanger, the steam inlet end of described acoustic velocity-variable supercharging heat exchanger is connected with steam-pipe, through feeding water, water pump is connected with feedwater piping cooling water inlet end, vapour-liquid exit end is connected with the entrance end of deoxygenator.
The cooling water inlet end of acoustic velocity-variable supercharging heat exchanger described in the utility model is connected with feedwater piping through feedwater water pump.
The utility model is connected with thermometer at the entrance end position of described deoxygenator.
The utility model is by connecting an acoustic velocity-variable supercharging heat exchanger on the steam-pipe at deoxygenator and feedwater piping, this acoustic velocity-variable supercharging heat exchanger is the heat-exchanger rig of vapour-liquid two-phase direct contact type, steam is as heating fluid, water is as being heated fluid, steam is thoroughly mixed to form stream-liquid two-phase flow with water after expanding in nozzle and forming high speed steam flow, in variable cross-section passage, produce condensation shock wave, steam all condenses into water, and leaving water temperature(LWT) and pressure are raise simultaneously.Make feedwater before entering deoxygenator, be heated to the boiling point of vacuum, directly enter deoxygenator and directly carry out deoxygenation, and do not heat with steam by pipeline, having solved steam mixes inhomogeneous problem with water, effectively improved oxygen removal efficiency.
