Abstract
The utility model discloses a dryer steam and liquid condensing system capable of effectively avoiding water attach, and the system comprises a rotary joint and a liquid condensing tank as well as at least one liquid condensing middle bag, wherein the rotary joint is arranged at one port of a dryer barrel and is connected with a steam source by virtue of a pipeline and a regulating valve; the liquid condensing tank is connected with the rotary joint of the dryer barrel by virtue of the pipeline; and the upper end and the lower end of each liquid condensing middle bag are respectively connected with the liquid condensing tank and the rotary joint by virtue of metal hoses. The dryer steam and liquid condensing system capable of effectively avoiding water attack disclosed by the utility model can be used for effectively avoiding water attack phenomena in two manners, namely a vacuum water column and secondary steam.
Description
Technical field
The utility model relates to the heat energy technology, the particularly a kind of drying machine steam and lime set system that can effectively avoid water attack to take place.
Background technology
Swinging steam multitube drying machine is a kind of widely used drying equipment, utilizes steam as thermal source, and under the indirect heat exchange effect of drying machine heat exchanger tube and material, the steam condensation generates lime set, derives, compiles through condensate pipe, accomplishes heat transfer process.
Conventional steam importing and lime set guiding system are following: steam is through control valve control flow; Get into swivel joint and drying machine cylindrical shell via metal hose; Derive through swivel joint and metal hose after heat exchange is accomplished, get into the lime set jar after merging and collect, accomplish heat transfer process.
This system is under the moderate situation of drying machine heat transfer intensity, and lime set can derive smoothly, operate as normal.But saturated at heat transfer intensity, promptly vapor portion forms lime set, and when part was also uncooled, the vapour-liquid amalgam was drawn via swivel joint and metal hose, and steam will continue the heat release condensation, forms parital vacuum.If the vacuum position is in the lime set delivery line, will cause water column accelerated motion under the effect of gravity and vacuum draw, in pipeline turning point generation water attack.Another kind of situation is: heat transfer intensity is not enough, and promptly steam is supplied with when having satisfied not heat exchange institute calorific requirement, the lime set that formation temperature is on the low side, and this moment, supercooled lime set got into the lime set jar of HTHP, will produce indirect steam, formed water attack.
Summary of the invention
The purpose of the utility model is to provide a kind of drying machine steam and lime set system that can effectively avoid water attack, effectively avoids the generation of the water hammer of these two kinds of forms of vacuum water column and indirect steam.
For achieving the above object, the technical scheme of the utility model is:
A kind of drying machine steam and lime set system that can effectively avoid water attack comprises that swivel joint is arranged at drying machine cylindrical shell one port, and connects vapour source through a pipeline and control valve; The lime set jar, it connects drying machine cylindrical shell swivel joint through pipeline; It also comprises, at least one lime set tundish, and it connects said lime set jar and swivel joint through metal hose respectively up and down.
Further, described lime set tundish is provided with two, is connected in series through metal hose, and is arranged in the pipeline of lime set jar and swivel joint.
Between described two lime set tundish two above metal hoses being set is connected in series.
Again, described lime set tundish respectively connects swivel joint and lime set jar respectively through two metal hoses up and down.
In addition, described lime set jar is connected with swivel joint between the pipeline of vapour source a pressure-equalizing passageway and corresponding pressure-regulating valve is set.
Have, the described lime set jar of the utility model is connected with swivel joint between the pipeline of vapour source a pressure-equalizing passageway and corresponding pressure-regulating valve is set again.
The beneficial effect of the utility model
The utility model is provided with the lime set tundish; The lime set generating capacity is bigger when designing; When the discrepancy in elevation between swivel joint and lime set jar is big, take two metal hose water outlets, the diameter of metal hose and length are all bigger; Lime set be can satisfy and traffic requirement, the stability and the security that can improve equipment again derived.
In addition, the lime set tundish is set and plays the function of eliminating the vacuum water column.Because the setting of tundish, the vapour-liquid amalgam will separate in tundish, even top steam condensation can not form strong pumping to the rear water column.Tundish is divided into short several sections with former long metal hose simultaneously, in the pipeline section of finite length, does not possess the condition that generates the vacuum water column.
Above the lime set jar, set up pressure-equalizing pipe; Promptly advancing to connect on the main steam header of drying machine an arm above the lime set jar; Inlet steam, drying machine heat exchanger tube, lime set jar three just become the integral body of a connection like this; Lime set relies on deadweight to discharge fully, has eliminated steam pressure or condensate vacuum to the influence that lime set derives, the formation of the lime set of avoiding excessively lowering the temperature.
Establishing pressure-regulating valve on the pressure-equalizing pipe, mainly is that control lime set pressure tank is in reasonable level.Judge heat transfer intensity in the drying machine through the lime set pressure tank, be responsible for steam flow, and guarantee that the lime set in the lime set jar can be extruded smoothly thereby suitably regulate.
The water hammer that the utility model can effectively avoid vacuum water column and indirect steam to cause, device security is guaranteed.Lime set can be discharged smoothly simultaneously, improves drying machine heat exchange effect.
