Description
Technical field
The utility model relates to the improvement of the used deaerating plants of all kinds of power plant such as a kind of thermal power plant, garbage incinerating power plant.Be a kind of membrane deaerator efficiently specifically.
Background technology
The deoxygenation of boiler feedwater is a crucial link in power plant, and existing oxygen-eliminating device mainly contains upright tower from the appearance, water tank two parts are formed.The shortcoming of these deaerating plants mainly is a complex structure, the operation noise is big, deaerating effect is unstable, can not guarantee the standard-required of boiler feedwater fully.
Summary of the invention
The purpose of the utility model is to overcome the shortcoming in the above-mentioned technology, a kind of architecture advances is proposed membrane deaerator, make that dissolved oxygen amount maintains below the 7 μ g/L all the time in the deaerated water, adaptability is strong, the operation noise is little, energy-saving effect is remarkable.
The purpose of the utility model is realized by following technical scheme: this membrane deaerator comprises oxygen-removing tower and water tank two parts; The hydroecium and the auxiliary steam chest of eddy flow jet pipe and downspout and upper spacer, median septum, lower clapboard composition are housed on the top of oxygen-removing tower; One side of hydroecium connects feed-water intake and mixes pipe, and a side of auxiliary steam chest connects air vent pipework, at the top of oxygen-removing tower water separator and blast pipe is housed; Eddy flow jet pipe below is the free swapace of carbonated drink; Trickle secondary distribution device and filler group are equipped with in the below of the free swapace of carbonated drink, are equipped with four groups in the bottom of oxygen-removing tower and rise the vapour cap, and the centre is a downpipe; Steam Pipe, downpipe and assistant heating pipe are housed on water tank, and water tank adopts crowd's pipe to be connected with oxygen-removing tower.
Between upper spacer, median septum, lower clapboard downspout and eddy flow jet pipe in-line arrangement or wrong row in proportion; And welding is fixing; Form the hydroecium on top and the auxiliary steam chest of bottom respectively, be distributed with the micropore by the rule discharging on the eddy flow jet pipe, the upper end of downspout is processed with the dirty otch of liquid.
The deoxygenation and the heat and mass transfer process of boiler feedwater are accomplished in oxygen-removing tower, the deoxygenation in feedwater following two stages of process:
Phase I, water mixes in eddy flow jet pipe, downspout and upper spacer that pipe gets into oxygen-removing tower top, the hydroecium that median septum is formed, through descending along the inwall eddy flow in the entering of the micropore on the eddy flow jet pipe eddy flow jet pipe from feed-water intake.The steam that rises gets into the eddy flow jet pipe from the bottom of eddy flow jet pipe; With the moisture film of ejection carry out after the heat and mass condensation with the eddy flow jet pipe in moisture film together flow downward; Water flow out behind the eddy flow jet pipe the free swapace of carbonated drink continue with the steam heat and mass that rises until falling into trickle secondary distribution device, redistribute the second time of accomplishing phase I deoxygenation and trickle.Incondensable gases such as the oxygen that is separated, carbon dioxide enter atmosphere through the water separator separation; Water is prevented from falling on the upper spacer; Otch through downspout flows down; Continue above-mentioned heat and mass transfer process with the steam that rises, reach the purpose of deoxygenation, also prevented the water that upper spacer is possible simultaneously.Second stage, feedwater get into filler after falling into trickle secondary distribution device, have further increased the carbonated drink contact area, accomplish the second stage deoxygenation.Steam gets into rising in the vapour cap the tower from the water tank Steam Pipe, gets into oxygen-removing tower through four groups of secondary distribution that rise the vapour cap, and the water heat exchange that elder generation and filler group are come is accomplished the second stage deoxygenation after trickle secondary distribution device gets into the free swapace of carbonated drink.It is subsequent use that water after the deoxygenation gets into water tank through downpipe.
When feedwater load change amplitude surpasses declared working condition, launch air vent pipework, make steam get into the auxiliary steam chest of median septum and lower clapboard composition; Micropore through the eddy flow jet pipe is the additional rotary power of feedwater under the eddy flow; Heat simultaneously, promote deoxygenation, thereby guarantee deaerating effect.
When the feed temperature in the water tank is on the low side, launch the assistant heating pipe, steam is got in the water in the water tank, carry out assistant heating, to keep normal water temperature, guarantee deaerating effect.
The utility model has the advantages that adaptability is strong, the operation noise is little, and energy-saving effect is remarkable, and the deaerated water dissolved oxygen amount is maintained below the 7 μ g/L all the time.
