Wherein, described inverted U pipe top is provided with vacuum-breaking valve.
Wherein, between described inverted U pipe and described condensate drum, be provided with valve.
Technique scheme tool of the present utility model has the following advantages: level of condensate provided by the utility model automatically controls and exhaust system utilizes pressure balance to realize condensate liquid automatic-discharging, the automatic control of this level of condensate and exhaust system can effectively be controlled the discharge of condensate liquid, realized system stable operation, the heat transfer effect that has increased evaporation concentrator, heat is fully utilized.
Accompanying drawing explanation
Fig. 1 is the structural representation of the automatic control of the utility model embodiment level of condensate and exhaust system.
In figure: 1: evaporation concentrator; 2: knockout drum; 3: inverted U pipe; 4: condensate drum.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, a kind of level of condensate that the utility model provides is controlled and exhaust system automatically, comprise evaporation concentrator 1 and condensate drum 4, evaporation concentrator 1 and condensate drum 4 are communicated with, evaporation concentrator 1 is communicated with knockout drum 2 imports, the condensate liquid producing from evaporation concentrator 1 enters into knockout drum 2 and carries out the vapor-liquid separation row buffering of going forward side by side, the high 1100mm of knockout drum 2, knockout drum 2 outlets are communicated with inverted U pipe 3 entrance points, the high 3600mm of inverted U pipe, inverted U pipe 3 ports of export are communicated with condensate drum 4, thereby condensate liquid from knockout drum 2 out by inverted U pipe 3 control system pressure and the liquid level that guarantees knockout drum 2, finally enter into condensate drum 4, this level of condensate automatically controls and exhaust system utilizes pressure balance to realize condensate liquid automatic-discharging, the automatic control of this level of condensate and exhaust system can effectively be controlled the discharge of condensate liquid, realized system stable operation, increased the heat transfer effect of evaporation concentrator, heat is fully utilized.
Preferably, knockout drum 2 tops are provided with pressure-equalizing pipe, and pressure-equalizing pipe can equilibrium separation tank 2 and the pressure of evaporation concentrator 1, and level of condensate is controlled automatically and exhaust system pressure is 30Kpa.
Preferably, inverted U pipe 3 tops are provided with vacuum-breaking valve, prevent that inverted U pipe 3 from producing siphon.
Preferably, between inverted U pipe 3 and condensate drum 4, be provided with valve, prevent from, in device running, occurring that the special circumstances such as level fluctuation can carry out emergency processing, guarantee system run all right.
As shown in Figure 1, when the utility model level of condensate is controlled automatically and exhaust system uses, condensate liquid produces and enters knockout drum 2 from evaporation concentrator 1, and condensate liquid enters inverted U pipe 3 from knockout drum 2, finally enters condensate drum 4.
In sum, level of condensate provided by the utility model automatically controls and exhaust system utilizes pressure balance to realize condensate liquid automatic-discharging, the automatic control of this level of condensate and exhaust system can effectively be controlled the discharge of condensate liquid, realized system stable operation, the heat transfer effect that has increased evaporation concentrator, heat is fully utilized.
Above embodiment only, in order to the technical solution of the utility model to be described, is not intended to limit; Although the utility model is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: its technical scheme that still can record aforementioned each embodiment is modified, or part technical characterictic is wherein equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of the utility model.
