Description
Technical field:
The utility model relates to a kind of air cooling condenser, especially relates to a kind of direct air cooling condenser tube bank.Be applicable to that there is the direct air cooling condenser of low temperature environment in the field of employment.Belong to air cooling heat exchanger technical field.
Background technology:
Directly the air cooling condenser tube bank is made up of following current tube bank, adverse current tube bank, steam-distributing pipe (upper header), condensate water lower collecting box etc., as Fig. 1.
At present, a lot of directly air cooling condensers cause the steam in the air cooling condenser tube bank very big with the heat transfer temperature difference of air with cold in the winter time area, the intrafascicular steam of condenser tube easy generation low-temperature condensate in condensation process.And have a certain amount of incoagulable gas in the direct air cooled condenser, incoagulable gas accumulation regions at heat-transfer pipe, low-temperature condensate freezes or frosting easily, As time goes on icing or frosting district can increase gradually, up to stopping up the condenser heat-transfer pipe, cause the tube bank bursting by freezing, influence the normal operation of whole system.
It is existing that known to prevent that heat-transfer pipe from freezing way as follows:
At the condensate water lower collecting box temperature measuring equipment is set, detects the temperature of condensate water in the lower collecting box.When temperature is on the low side, take antifreezing measures; At adverse current tube bank bleeding point temperature measuring equipment is set, detects the temperature of adverse current tube bank bleeding point steam and incoagulable gas mixture.When temperature is on the low side, take antifreezing measures.
But these tube bank measuring points can not accurately and timely detect tube bank and have bursting by freezing danger, mainly be the on the low side or condensate undercooling of lower collecting box condensing water temperature be higher than setting value all can not reflection system accurately and timely in a certain heat-transfer pipe or restrain certain part and had apparent freezing point because freezing of these parts may not can cause variation to this comb bundle (being made up of hundreds of root heat-transfer pipe) lower collecting box condensing water temperature.Same adverse current tube bank bleeding point temperature is on the low side can not be accurately and timely the reflection reverse stream pipe intrafascicularly had hoarfrost point, so winter heat-transfer pipe the phenomenon of freezing still often occur.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of and can accurately and timely detect the direct air cooling condenser tube bank that danger is freezed in the tube bank existence.
Theoretical and experiment shows that all there are the zone that easily freezes in following current tube bank, adverse current tube bank under low temperature environment, be respectively described below:
In the following current tube bank, steam is respectively along last, two row's heat-transfer pipes flow downward down, in the winter time under the environment temperature situation on the low side, arrange the heat transfer temperature difference of the heat transfer temperature difference of heat-transfer pipe down much larger than last row's heat-transfer pipe, row's heat-transfer pipe steam condensation number is big so down, the pressure of arranging the heat-transfer pipe bottom down will less than on row heat-transfer pipe bottom pressure, steam in the row's of causing heat-transfer pipe (mixing incoagulable gas) flows into the bottom of row's heat-transfer pipe down, form the incoagulable gas accumulation regions in the bottom of arranging heat-transfer pipe down, low-temperature condensate is process incoagulable gas accumulation regions in the process that flows into lower collecting box, and (seeing Fig. 2 following current tube bank shadow region, bottom) easily freezes.But the temperature measuring equipment very first time is set herein to be detected heat-transfer pipe and freezes.
Reverse stream pipe is intrafascicular, condensing vapour is upwards not mobile along upper and lower two row's heat-transfer pipes respectively through the condensate water lower collecting box in the following current tube bank, in the winter time under the environment temperature situation on the low side, arrange the heat transfer temperature difference of the heat transfer temperature difference of heat-transfer pipe down much larger than last row's heat-transfer pipe, row's heat-transfer pipe steam condensation number is big so down, the pressure of arranging heat-transfer pipe top down will less than on row's heat transfer upper pressure, the part incoagulable gas on the row of causing heating surface bank top top of comb bundle under the inflow before by the vavuum pump extraction.Incoagulable gas accumulates in down the easy frosting in top of row's heat-transfer pipe for a long time or freezes (seeing Fig. 2 adverse current tube bank shadow region, top).But the temperature measuring equipment very first time is set herein detects the heat-transfer pipe frosting.
The purpose of this utility model is achieved in that a kind of direct air cooling condenser tube bank, comprise steam distribution upper header, following current tube bank, adverse current tube bank and condensate water lower collecting box, described steam distribution upper header is restrained to be connected with following current and is communicated, the following current tube bank is connected with the condensate water lower collecting box and communicates, the condensate water lower collecting box is restrained to be connected with adverse current and is communicated, it is characterized in that: in following current tube bank bottom following current tube bank temperature measuring equipment is set, or/and adverse current tube bank temperature measuring equipment is set on adverse current tube bank top.
When there was icing zone in following current tube bank heat-transfer pipe, the temperature at following current tube bank temperature measuring equipment place will quickly fall to 0 ℃, can detect heat-transfer pipe timely and have bursting by freezing danger; When there was frosting in adverse current tube bank heat-transfer pipe or freezes the zone equally, the temperature at adverse current tube bank temperature measuring equipment place will quickly fall to 0 ℃, can detect the heat-transfer pipe existence timely and stop up or bursting by freezing danger.
