Abstract

The utility model provides a moisture separator including a tank body, and a separating box in the tank, a drainage pipeline, which is characterized in that the interval fixing component between the wave plates with hooks in the separating box in the tank is a rigid block whose shape is the same with that of the gap between the wave plates with hooks, the position of the rigid block corresponding to each hook of the wave plate with hooks is provided with a small via hole. The rigid block is difficult to cause deformation thus to ensure the assembly precision and keep the drainage clear; the drainage pipeline of the drainage system is reasonable in structure, and is difficult to occur back flow of the gas flow thus to cause secondary water condensing. And the utility model is simple and compact in structure, convenient to be designed in series and assembled, low in cost.

Description

Steam-water separator

The utility model belongs to a kind of moist steam treatment facility, is a kind of steam-water separator specifically.

At present, the core parts of steam-water separator separator box generally all adopt advanced buckle corrugated sheet structure, and its resiliency supported sheet of separating the clamping corrugated sheet is easy to generate distortion, causes the hydrophobic aperture dislocation on corrugated sheet groove and the bottom plate, causes hydrophobic not smooth.In addition, air-flow takes place and pours in down a chimney and cause secondary band water in the drain pipe Louis of draining system.

The purpose of this utility model is to provide a kind of steam-water separator at the deficiencies in the prior art, and its fixed interval parts of separating the clamping corrugated sheet are not easy to produce distortion, can guarantee assembly precision, make hydrophobic keeping clear; The hydrophobic pipeline of draining system is rational in infrastructure, air-flow be difficult for to take place pour in down a chimney and cause secondary band water.And simple in structure, compact, be convenient to seriation design and assembling, cost is lower.

The purpose of this utility model is achieved by the following technical solution: a kind of steam-water separator, comprise the dry saturated steam outlet on tank body, tank body top, the moist steam import of tank body bottom, the hydrophobic outlet of tank base and separator box, the hydrophobic pipeline in the tank body, it is characterized in that in the separator box in the described tank body fixed interval parts between the buckle corrugated sheet for the buckle corrugated sheet between the identical rigidity spacer block of gap shape, the hook portion of corresponding each buckle corrugated sheet all has a small through hole on the rigidity spacer block.

Described buckle corrugated sheet withstands fastening by the trip bolt on the sidewall of separator box two ends.

Have apopore on the lower box bottom surface of described separator box, be connected to funnel below the corresponding apopore, be connected to hydrophobic pipeline below the funnel.

The meander sections that one " 0 " shape is arranged in the described hydrophobic pipeline.

The utility model compared with prior art has many advantages and good effect:

1, since separator box in corrugated sheet between the fixed interval parts be with corrugated sheet between the identical rigidity spacer block of gap shape, be not easy to produce distortion, guaranteed assembly precision, the hook portion of corresponding each corrugated sheet all has a small through hole on the rigidity spacer block, makes hydrophobic keeping clear;

Air-flow be difficult for to take place and pours in down a chimney and cause secondary band water in the meander sections that 2, one " 0 " shape is arranged in the hydrophobic pipeline;

3, simple and reasonable for structure, compact, be convenient to seriation design and assembling, cost is lower, is specially adapted to middle-size and small-size steam-water separator.

Below in conjunction with accompanying drawing the utility model is described in further detail:

Referring to Fig. 1-Fig. 5, a kind of steam-water separator is made up of the dry saturated steam outlet 3 on tank body 2, tank body 2 tops, the moist steam import 1 of tank body 2 bottoms, the hydrophobic outlet 8 of tank body 2 bottoms and separator box 4, the hydrophobic pipeline 5 in the tank body 2.Separator box 4 is to be made of upper box 9, lower box 11, sidewall and interior buckle corrugated sheet 12 splitters thereof, splitter is one group to have waveform and has the stainless steel substrates of drawing together the water hook at the turning and form, buckle corrugated sheet 12 is vertically installed, the rigidity spacer block identical with the gap shape 13 all is housed at interval in the gap of each corrugated sheet 12, and by the trip bolt 10 on the separator box 4 two ends sidewalls that buckle corrugated sheet 12 is fastening.The hook portion of corresponding each buckle corrugated sheet 12 all has a small through hole 16 on the rigidity spacer block 13, have apopore 15 on lower box 11 bottom surfaces of separator box 4, be connected to funnel 14 below the corresponding apopore 15, be connected to hydrophobic pipeline 5 below the funnel 14, so that the moisture content that hook portion is drawn together out is dredged in the funnel 14 of splitter bottom, discharge by hydrophobic pipeline 5 then.

The utility model has adopted Gravity Separation to separate two step separated structures with buckle corrugated sheet 12.Gravity Separation mainly is to separate diameter greater than the water particle more than the 0.1mm, as crude separation; And buckle corrugated sheet 12 to separate mainly be to separate the tiny water particle of diameter less than 0.1mm, as segmentation from, to reach better effect.After moist steam entered separator, earlier through one section rising space, the effect owing to gravity in this section rising space of larger-diameter water particle fell into the separator bottom, is discharged by hydrophobic outlet 8 then.All the other water particles (fog) than minor diameter then by steam bring into segment in the splitter of forming by buckle corrugated sheet 12 in the separator box from.The isolated moisture content of splitter has the hydrophobic pipeline 5 of the meander sections 6 of " 0 " shape that moisture content is dredged out separator tank body 2 by one.If directly the hydrophobic of splitter dredged into the bottom in the tank body 2, then might cause splitter secondary band water, because when vapor stream is crossed splitter, have bigger flow resistance, before and after the splitter certain pressure reduction is arranged, splitter is isolated hydrophobic, might be under the effect of this pressure reduction, flow backwards back in the splitter, the steam that is flowed is taken away, and does not reach the effect of separation.On hydrophobic pipeline 5, be connected with drain valve 7.
