Abstract

The utility model discloses a heat-energy gas recycling-device. The utility model adopts the technical plan that an outer helix-piece is arranged between the casing and the inner cylinder in which an inner helix-piece is arranged to make use of the curve characteristics of double helix-body to enlarge the liquid exchanging-area and also to raise the heat-exchanging quantity so as to make the heat energy in the waste-gas absorbed by the inner pipes; the waste gas is driven by the inner helix-piece to move in a helix-way then to generate a centrifugal-force which impacts the gas-granule to form gas drops which is produced by the colliding between the bigger granules under the aggregation effect caused by the centrifugal-force; the gas drops fall down to the gas-guiding web under the effect of gravity; and the gas-guiding thread of the gas-guiding web which is with a titanium-plating bears a better gas-filtering effect; the gas finally enters the gas-tank along the gas-guiding column.

Description

The heat energy device for recovering oil and gas

Technical field

The utility model discloses a kind of waste gas recovering device, be meant a kind of heat energy device for recovering oil and gas especially.

Background technology

Use in the industry of supersaturated vapor in textile printing and dyeing industry, leather manufacturing industry etc., discharged large quantity of exhaust gas, contain oxious components such as flue dust, oil stain in the waste gas, there is a large amount of waste heats to be discharged into air simultaneously, dispersed heat not only wastes energy, and cause environmental pollution, therefore, this industrial waste gas is effectively administered, waste gas residual heat is reclaimed, and the sustainable development of industries such as this environmental pollution that improvement industry cluster is brought, comprehensive utilization recycling economy and printing and dyeing, leather all is significant.The invention waste gas atomization absorption treatment device that October 26, disclosed publication number was CN1686595A in 2005, though can effectively handle forming machine waste gas, the heat in the waste gas is recycled, but because the restriction of structure, recovering effect haves much room for improvement.

The utility model content

For addressing the above problem, the purpose of this utility model is to provide a kind of heat energy device for recovering oil and gas with high efficiente callback.

For achieving the above object, the technical solution adopted in the utility model is: comprise support, place the cylindrical housing of being with waste gas inlet and waste gas gas outlet on the support, above shell, be provided with hot-air mouth, the below is provided with the cold wind mouth, inner core places in the shell, it also is cylindrical shape, shell adopts low Heat Conduction Material to make, and externally wrap up insulation material, inner core adopts the high dielectric material of the coefficient of heat conduction to make, as red copper, stainless steel etc., between shell and inner core, be provided with the external spiral sheet, the flight dead ring is around the inner core outside, be installed with oil guidance column in the middle of the inner core, on oil guidance column, be interval with several oil guiding nets, oil guiding net is conical and is fixed on the oil guidance column, in the present embodiment, oil guiding net is center line with the oil guidance column, with the fixed in shape of inverted cone on oil guidance column, the quantity and spacing of oil guiding net can be according to the design needs relative set of this unit scale, preferably oil guiding net is arranged at the position, middle and lower part of oil guidance column, because oil gas has just also had higher temperature when air inlet enters, therefore the position with oil guiding net moves down, oil gas can better be aggregated on the oil guiding net when temperature reduces, and the oil guiding silk that is used for being combined into oil guiding net preferably adopts technology for plating titanium, can accelerate the polymerization of oil gas particle, prevent that oil gas is discrete, reach better oil strain effect.

It is also to be provided with inner screwy fin in inner core that the utility model further improves, and inner screwy fin is fixed in the inner core by support bar, and support bar preferably adopts three so that inner screwy fin is more firm.

The utility model sets firmly inner screwy fin by the external spiral sheet is set in inner core between shell and inner core, when exhaust gases enters from air inlet, by inner screwy fin and oil guiding net, discharge from the gas outlet; Natural wind enters simultaneously from the cold wind mouth of below, right side, by the external spiral sheet, discharges from hot-air mouth.Because exhaust gases is opposite with the direction of motion of natural wind, thereby produce forced convertion at inside and outside flight, utilize the curve characteristic of binary spiral, increased the exchange area of fluid, increased heat exchange amount, heat energy in the exhaust gases is fully absorbed by interior pipe, and absorb by natural wind, be converted into hot-air at last and be used by the conduction of external spiral sheet heat; And the oil gas in the exhaust gases; because exhaust gases is in the inner screwy fin motion of spinning; produce centrifugal force; the oil gas particle is under action of centrifugal force; the particle that the part particle diameter is bigger can produce collision; and because heat energy is further absorbed; the temperature of oil gas becomes characteristic makes the oil gas particle produce polymerization formation oil droplet under action of centrifugal force; and under the effect of gravity, fall, in the oil droplet dropping process, touch oil guiding net; oil guiding silk through technology for plating titanium on the oil guiding net has oil strain effect preferably; thereby further accelerate the polymerization of oil gas, form the oil droplet of larger particle, and finally enter into oil trap along oil guidance column.

Further illustrate detailed content of the present utility model below in conjunction with the drawings and Examples explanation.
