Abstract

The utility model relates to an exhausted steam recoverer which comprises a shell (1), a steam outlet which is arranged on the top of the shell (1), a water outlet which is arranged at the bottom of the shell (1), and a steam inlet which is arranged at the side lower part of the shell (1); the exhausted steam recoverer is characterized in that the inner cavity of the shell which is above the steam inlet is subsequently provided with a plurality of layers of absorption trays (4); a water spray pipe (2) is arranged above the top absorption tray; each absorption tray (4) consists of a plurality of slat-shaped components (5) which have inclined cross section and Z-shaped structure and are staggered and stacked, and the upper and the lower matching surfaces of the staggered and stacked parts are matched with spacing between; the slat-shaped components (5) of every two adjacent upper and lower layers of absorption trays (4) are staggered longitudinally and transversely in 90 degrees; the bottom of the grooves of the slat-shaped components (5) is provided with a plurality of water leakage holes along the length direction.

Description

A kind of water vapour exhaust steam recoverer

Technical field

The utility model relates to a kind of water vapour exhaust steam recoverer, is suitable for the recovery of big flow minute-pressure exhaust steam, and this equipment can be widely used in industries such as oil, chemical industry, metallurgy, electric power.

Background technology

Often produce a large amount of water vapour exhaust steam in the industrial production field, low owing to this exhaust steam pressure, density is little, slow being difficult to of flow velocity reclaim, industrial normal employing cold water mixes the recovery heat with exhaust steam, traditional reclaimer often cause because of complex structure minute-pressure steam be difficult to by, do not reach recovering effect, and undue simple carbonated drink mixing apparatus does not reach recovering effect equally because the insufficient steam that makes of steam contact runs off in a large number.

Summary of the invention

The purpose of this utility model provide at existing weak point in the big flow minute-pressure water vapour exhaust steam recovery technology in the above-mentioned prior art just that a kind of structure is more reasonable, recovering effect is good the water vapour exhaust steam recoverer.

The purpose of this utility model realizes by following technique measures:

The utility model water vapour exhaust steam recoverer exhaust steam recoverer, the air intake that it comprises housing, is arranged on the venthole of case top, is positioned at the delivery port of housing bottom and is arranged on the case side below; Set gradually the several layers absorption tray from the bottom to top at the housing inner chamber that is arranged in above the air intake, above the top layer absorption tray, be provided with spray pipe; Described absorption tray is to be arranged in the mode of staggered hasp by the slab member that many cross sections are the Z-shaped structure of tilting (about 45 °) to form, and the mating surface up and down of its staggered hasp part is matched in clearance; The slab member of per two adjacent upper and lower two-layer absorption traies is 90 ° and is criss-cross arranged (promptly, if the slab member of its upper strata absorption tray is the vertical equity setting, the slab member that then is positioned at the absorption tray of below should be with the mode transverse horizontal setting of half-twist); Bottom portion of groove at described slab member is processed with leaking hole.

Several layers absorption tray described in the utility model sets gradually in the rectangle cylindrical shell from the bottom to top, and this rectangle cylindrical shell is fixedly mounted in the housing inner chamber of air intake top, spray pipe below by connector.

Operation principle of the present utility model and beneficial effect are as follows:

The minute-pressure water vapour exhaust steam that produces in the industrial production is from the housing inner chamber of the air intake access arrangement of lower housing portion, cold water is from being positioned at the spray pipe ejection of absorption tray top, be uniformly distributed in the absorption tray, when shower water drops to slab member (the Z-shaped structure that cross section is tilting (about 45 °)) in the absorption tray, the front end edge skew wall of part water slave plate strip member flows down, part water flows down from the skew wall of centre, and contact with the water vapour that flows from bottom to top by the gap between the mating surface up and down of staggered hasp part between adjacent slab member, carry out mass-and heat-transfer, flow to afterwards on the skew wall of centre of slab member, flow in the groove of bottom of slab member from skew wall then, water must flow laterally to nearest tapping and just can drop in one deck absorption tray in groove, and this has also prolonged with baffling the time that water vapour excessively contacts.Because water vapour exhaust steam pressure in flow process is very low, flow velocity is very slow, so simple baffling is very little to the loss of water vapour build-up of pressure, can be with the steam resistance in the bottom, water vapour is easy to arrive its upper side from the equipment bottom, makes all from top to bottom absorption traies of entire equipment can both reach a kind of high efficiency user mode.The exhaust steam residual heat that can be widely used in industries such as oil, chemical industry, metallurgy, electric power reclaims, and is a kind of energy-saving equipment of highly effective.

The specific embodiment

The utility model is described further below in conjunction with embodiment (accompanying drawing):

The air intake 6 that the utility model water vapour exhaust steam recoverer comprises housing 1, is arranged on the venthole 8 at housing 1 top, is positioned at the delivery port 7 of housing 1 bottom and is arranged on housing 1 side-lower; Set gradually several layers absorption tray 4 from the bottom to top at the housing inner chamber that is arranged in above the air intake, above the top layer absorption tray, be provided with spray pipe 2; Described absorption tray 4 is to be arranged in the mode of staggered hasp by the slab member 5 that many cross sections are the Z-shaped structure of tilting (about 45 °) to form, and the mating surface up and down of its staggered hasp part is matched in clearance; The slab member 5 of per two adjacent upper and lower two-layer absorption traies 4 is 90 ° and is criss-cross arranged (promptly, if the slab member of its upper strata absorption tray is the vertical equity setting, the slab member that then is positioned at the absorption tray of below should be with the mode transverse horizontal setting of half-twist); Bottom portion of groove at described slab member 5 is processed with some leaking holes along its length direction; Described several layers absorption tray 4 sets gradually in the rectangle cylindrical shell 3 from the bottom to top, and rectangle cylindrical shell 3 is fixedly mounted in the housing inner chamber of air intake top, spray pipe 2 belows by connector.
