Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an eco-

The present invention relates to an apparatus for producing pure steam, more specifically, an eco-efficient high efficiency steam filtration apparatus which completely removes condensed water and impurities from the generated steam and has high thermal efficiency.

The use of steam in a variety of applications is common in the general industry.

Steam is used in a variety of applications including cogeneration plants, heating systems, food processing, precision medicine, and the semiconductor industry.

Therefore, in the field of using steam, the technique of obtaining pure steam containing no impurities is the key.

Although the use of steam is widely used in industry, it is difficult to remove condensed water and impurities contained in steam owing to the structural weakness of the equipment. To solve this problem, expensive equipment and equipment have to be added.

Japanese Patent Application Laid-Open No. 10-1106072 (hereinafter referred to as " impurity removing device for centrifugal force filter system ", hereinafter referred to as " prior art ") discloses a device for removing impurities from a fluid having a high viscosity and for discharging the impurities to the outside, A driving motor for rotationally driving the rotary shaft; and an inner cylinder attached with impurities desorbed by the rotation of the filter, the inner cylinder being spaced inward from the inner wall of the housing, And a method for dropping impurities adhering to the inner cylinder by steam injected between the housing and the inner cylinder from a steam generating device is disclosed.

However, the prior art and the prior art have a complicated structure, lowered purity of steam, and also remove steam impurities by using a driving force such as a motor, which causes a problem of high energy consumption and inefficiency.

SUMMARY OF THE INVENTION The present invention seeks to solve the problems and needs of the conventional steam filtration technology and the prior art described above.

As described above, although the use of steam is variously utilized as described above, it is not easy to remove condensed water and impurities mixed in the steam due to the structural weakness of the equipment. To solve the problem, expensive equipment and equipment are added. And there is a problem in generation and maintenance of the steam filtration apparatus.

The conventional steam filtration apparatus has a disadvantage in that it can not obtain an effective cyclone effect on steam by forming a vertical diaphragm on the inner wall of the conventional housing.

In addition, the existing steam filter technology has a porous partition wall on the inner wall to separate the steam from the steam by the rotation, and the filter with the tourmaline processing stone inserted to remove the impurities (such as iron oxide and scale) contained in the steam. As a key technology.

However, a test analysis of these two technical characteristics revealed that significant defects were produced in commercialization. First, a porous partition wall is installed on the inner wall to induce steam separation through the rotation of the steam. However, there is a problem that the steam is not rotated due to the resistance of the partition wall.

Also, the use of filters using tourmaline resulted in more serious fouling secondary contamination by commercialization with even greater defects. The reason is that the application does not understand the nature of the steam. In other words, the flow of steam at high temperature and high pressure contains high frictional force and energy, but it can not withstand the strength and processing method of the tourmaline processing stone to be used. As a result, powder is generated and powder of clay component is produced. The present invention is intended to solve this problem.

Therefore, the steam from the above-described steam filtration device can not be used in food processing, precision medicine, and semiconductor industries, and can not be regarded as a steam filter. Instead, it has a problem of supplying more contaminated steam through additional contamination To solve this problem.

Also, in the conventional steam filtration apparatus, it is not effective to separate the condensed water separated from the steam, so that the condensed water is scattered again.

In order to solve the above problems and needs,

A steam inlet portion 200 and a steam outlet portion 300 are provided in the housing 100,

And a filtering filter unit 500 and a condensed water receiving unit 600 are provided in the housing.

The housing is divided into an upper housing 110 and a lower housing 120,

And a steam induction plate 700 and a condensate backflow preventing diaphragm 800 are provided in the lower housing.

Also, the filtration filter unit 500 provides a vapor filtration apparatus characterized by being a double fine mesh net filter type filtration filter unit filled with an adsorbent.

Also provided is a steam filtration system characterized by further having a scrubber screen (400).

The present invention greatly facilitates the removal of condensed water and impurities, eliminates the need to add expensive equipments and equipment, and produces high cost and maintenance-free effects.

Further, according to the present invention, a steam induction plate is formed inside the housing to enhance the cyclone effect of the steam, thereby easily removing condensed water (or dew condensation water) and impurities.

In addition, the present invention provides an effect of preventing the condensed water from being scattered due to the high-temperature and high-pressure steam because the condensed water backflow prevention diaphragm is constituted.

Further, the present invention has the effect of removing the condensed water and the impurities contained in the steam by a second order by constituting the multiple scrubber screen.

Further, according to the present invention, a double-fine mesh mesh filter type filter portion is constituted to generate a remarkable effect of removing the condensed water and impurities contained in the steam in a tertiary manner. In particular, by using alumina silica balls as an adsorbent The secondary contamination of the vapor due to the conventional adsorbent or absorbent can be remarkably prevented.

Hereinafter, the present invention will be described with reference to the drawings.

The present invention provides a steam filtration apparatus having a steam inlet portion 200 and a steam discharge portion 300 in a housing 100 and a filtering filter portion 500 and a condensed water receiving portion 600 in the housing do.

As shown in FIG. 1, the housing 100 of the present invention means an apparatus or means for forming a void space therein to provide a space through which steam is introduced and from which steam is discharged.

Therefore, it is preferable that the housing is generally formed into a cylindrical shape, but not limited thereto, and it may be a polygonal shape.

The housing includes a steam inlet portion 200 and a steam outlet portion 300.

The steam inlet 200 means a device or structure for introducing steam generated in a steam generator such as a boiler into the interior of the housing.

The steam inlet is tubular but is not limited thereto.

The steam inlet is preferably connected to the side portion of the housing so that the steam can flow into the housing and the steam can rotate inside the housing.

And the inlet end 210 of the steam inlet may be formed in the lower end of the housing so that the steam can enter the lower end of the housing with respect to the horizontal plane.

Since the angle of incidence of the steam is effectively from 0 to 60 degrees, the inlet end of the steam inlet may be formed to be between 0 and 60 degrees.

Due to the shape or structure of the steam inlet, the steam introduced into the housing rotates more effectively.

In addition, the steam inlet may be structured to be connected to the following steam guide plate, so that the rotation of the steam can be more effectively induced.

The steam outlet 300 means a device or structure which is discharged after the steam introduced into the housing is removed.

The steam outlet is also formed in a cylindrical shape and is formed on the side surface of the housing, but is not limited thereto.

The steam outlet portion 300 is connected to the filter portion 500, and allows the steam passing through the filter portion to be discharged.

The steam outlet portion is connected to the filtration filter portion and the steam induction pipe 310.

The present invention can be divided into an upper housing 110 and a lower housing 120.

It should be understood that dividing the housing into an upper housing and a lower housing in the present invention is described as a method for further describing the technical contents of the present invention.

1, the housing separates the upper housing 110 from the upper housing 120 on the basis of the coupling flange A formed in the middle of the housing.

Therefore, the steam filtration apparatus of the present invention can be manufactured by separately manufacturing the upper housing and the lower housing and combining them by a general coupling means such as a flange or the like.

This simplifies and simplifies the operation with the functions and operation effects.

In the present invention, a condensate water receiver 600 is provided in the lower end of the lower housing.

The condensate water circulation unit 600 is a device or structure for providing a space in which condensed water formed by condensation or condensation of separated water and steam is separated into vapor separated from the vapor introduced into the housing it means.

As shown in FIG. 1, in one embodiment, the condensate water receptacle is formed at the lower end of the housing and has a funnel-shaped structure or shape, but is not limited thereto

A condensate water outlet 610 is formed in the condensate water collector to discharge the condensed water to the outside of the housing.

Therefore, a valve 620 is provided at the condensed water discharge port to open the valve to discharge the condensed water when the condensed water is discharged.

One technical feature of the present invention is that the lower housing has the steam induction plate 700 to induce the condensed water into the condensed water receptacle while rotating the introduced steam, thereby facilitating gas-liquid separation.

The steam induction plate 700 is in the form of a plate attached to the inner wall of the lower housing and is formed along the lower portion of the lower housing and has a constant height toward the interior.

It is preferable that the height formed at a certain height is about 1/20 to 1/10 of the diameter of the housing, but it is not limited thereto and it can be formed according to the demand of the size of the steam filtering apparatus.

The steam guide plate may also be in a continuously connected form, but not necessarily in a fully connected form.

Therefore, the steam induction plate may have a constant inclination in the direction in which the steam is rotated, but may consist of one or more steam.

The steam induction plate induces the effect of increasing the rotational force on the steam introduced into the housing (i.e., the cyclone effect), thereby causing the gas-liquid separation to occur more effectively, and removing the impurities to separate the high-quality steam.

That is, the cyclone effect means that the liquid and impurity have a much larger specific gravity than the gas, so that the liquid is rapidly centrifuged and removed by the rotational force, so that the gas-liquid separation is more likely to occur if the cyclone effect is large.

It is more effective that the above-mentioned steam induction plate is preferably a helical steam induction plate 710.

As shown in FIG. 2, the steam induction plate is formed in a spiral shape along the inner wall of the housing.

In this case, the spirally wound induction plate is in a continuously connected form, thereby increasing the cyclone effect more effectively.

The present invention has a function of primarily removing condensed water from the steam introduced into the housing.

The technical feature of the present invention is that the condensate backflow prevention diaphragm 800 is configured.

As shown in FIG. 3, the condensate water backflow preventing diaphragm is formed on the upper portion of the condensate water passage and is formed inside the lower housing.

The counterflow prevention diaphragm 810 is formed in a plate shape.

The steam is introduced and discharged through the passage, and the condensed water that is scattered is blocked by the plate.

The size of the opening may be about 1/5 to 1/2 of the diameter of the lower housing.

The diaphragm backflow prevention diaphragm is more preferably a conical backflow preventing diaphragm. The conical direction is in the lower direction of the lower housing.

Conical condensate backflow prevention diaphragm is more effective when the rotating steam flows into the condensate water can more smoothly and it has a high effect of blocking the condensed water which is scattered.

As shown in FIG. 3B, the steam backflow preventing diaphragm of the present invention has a steam flow hole 820 formed at a portion contacting the inner wall of the lower housing, so that the steam can be easily flowed along the inner wall of the lower housing through the condensed- .

The condensate backflow prevention diaphragm formed with the steam flow port may be formed along a surface contacting the inner wall of the housing. The condensation water backflow prevention diaphragm may be connected to the lower housing by the connection portion 830.

As described above, the condensed water backflow prevention diaphragm according to the present invention can prevent the condensed water backflow prevention diaphragm from flowing into the condensed water receiving part 600, which is the lower part of the housing, while the introduced steam rotates inside the housing, Thereby preventing the condensate from being re-dispersed.

In addition, a major technical feature of the present invention is that a scrubber screen 400 is formed inside the housing to perform the function of removing secondary condensate and removing impurities.

As shown in FIG. 4, the scrubber screen has a plate shape and has a plurality of filter holes 410 formed therein.

In the present invention, the diameter of the filter hole 410 is not limited, but it is effectively 1 to 5 mm.

In the center of the scrubber screen, a coupling hole 420 may be formed so that the steam discharge induction pipe can be coupled, but it is not essential.

The scrubber screen functions to remove secondary condensate and remove impurities before the steam having undergone removal of condensate and impurities from the lower housing flows into the filtration filter unit 500 formed in the upper housing.

That is, the filter hole 410 having a small diameter is formed on the scrubber screen, so that the steam passes through the filter hole and is accelerated and strikes against the scrubber screen formed as a plate. Thus, the number of dew condensation and impurities It will be removed.

That is, when a substance having a different specific gravity is mixed in the fluid, the substance in the fluid is removed by the blocking effect by the screen.

As shown in FIG. 4B, it is preferable that the filter hole of the scrubber screen of the present invention is formed in a certain shape.

Accordingly, the scrubber screen is in the form of a disk, and a coupling hole 420 is formed at the center of the scrubber screen so that the steam discharge induction pipe can be coupled thereto, and the filter holes 410 are formed in a constant array along the circumference .

When the multi-scrubber screen is constructed with such a scrubber screen structure, it is easy to configure the filter holes to be staggered from each other, and the degree of staggering can be configured by the convenience of the user, thereby enhancing the secondary condensate and impurity removal effect.

The hole 421 shown in FIG. 4B means a fastener 421 which can be coupled with a filtration filter part to be described below with a bolt or the like.

In addition, the present invention provides a multi-scrubber screen 400 'in which the above-described scrubber screen is formed in multiple stages, thereby further enhancing the effect of removing secondary condensate and removing impurities.

The multiple scrubber screen means that the scrubber screen is composed of two or more scrubbers, but the scrubber screens are formed at regular intervals.

As shown in FIG. 5, the multiple scrubber screen means that the scrubber screen is formed by overlapping the scrubber screens at regular intervals.

Therefore, in the multi-scrubber screen, the filter space portion 430 is formed between the scrubber screens, and the effect of removing condensation water and impurities contained in the steam is enhanced in the filter space portion.

Preferably, the multi-scrubber screen is constructed such that the positions of the filter holes formed in the scrubber screen do not coincide with each other, that is, they are offset from each other.

Such a staggered filter hole structure enhances the efficiency of the steam passing through the filter hole against the scrubber screen plate, thereby remarkably enhancing the blocking effect, thereby completely removing condensation water and impurities.

The condensed water and the impurities which are cut off from the scrubber screen are introduced into the condensate water receptacle of the lower housing to be removed.

Also, in the present invention, the steam passing through the scrubber screen enters the filtration filter unit 500 and functions to remove the condensed water and impurities in the third order.

The filtration filter unit is connected to the steam discharge pipe to finally discharge the steam.

The filtration filter portion in the present invention means a device or means for filling a conventional adsorbent such as zeolite, tourmaline or the like or an absorbent.

Therefore, the adsorbent or the absorbent used in the filtration filter portion may be either a natural or synthetic absorbent or an absorbent.

However, the present invention is also a double-fine mesh mesh filter type filter filter unit 500 having a large technical feature in the above-described filter filter unit and further enhancing the effect of removing condensed water and impurities.

As shown in FIGS. 6 and 7, the double-fine mesh mesh filter type filter unit 500 of the present invention includes a primary mesh membrane unit 510, a secondary adsorbent charging unit 520, a tertiary mesh membrane unit 530, (540).

In the primary mesh portion of the present invention, a filtration opening 511 is formed. As the vapor passes through the filter chamber, the filtering effect (that is, the blocking effect) as described above acts to remove the condensed water and the impurities.

It is preferable that the filter mouth of the primary mesh portion is formed to have a size smaller than the diameter of the adsorbent to be used.

In the present invention, the secondary adsorbent charging section has a great technical characteristic.

As described above, the zeolite or tourmaline used as the adsorbent is subject to abrasion and abrasion due to high-pressure and high-temperature steam introduced into the steam filtration apparatus at a rate of 7 atm (kg / cm ³ ) or more.

Such abrasion and abrasion of the adsorbent significantly deteriorates the quality of the steam and causes a problem of increasing the pollution on the hygienic side.

Thus, the inventor of the present invention has used alumina ceramic balls as the adsorbent.

The alumina ceramic balls of the present invention have remarkably high strength and hardness, and thus have remarkable advantages that no abrasion or abrasion occurs even at the high temperature and high pressure steam.

The above-mentioned alumina ceramic balls are manufactured by molding an alumina component, a tourmaline ore particle, a magnetic particle and a functional ceramic particle, kneading the mixture into particles, heat-treating the mixture at a temperature of 1,500 to 3,000 ° C, to be.

The above-mentioned functional ceramic particles mean particles containing a common ceramic component, and may include one or a mixture of two or more materials selected from the group consisting of an elvan ceramic, a coral ceramic ball, a calcium ceramic, and a zeolite ceramic.

The above-mentioned magnetic particles include Fe3O4 or gamma-Fe2O3 and include magnetic particles.

The above alumina ceramic balls are prepared by kneading 100 parts by weight of an alumina component with 50 to 80 parts by weight of tourmaline ore particles, 50 to 80 parts by weight of magnetic particles and 150 to 300 parts by weight of functional ceramic particles.

The present invention also relates to a process for producing an alumina component, which comprises adding 0.5 to 2 parts by weight of manganese oxide, 0.5 to 2 parts by weight of silica oxide, 0.5 to 2 parts by weight of cerium oxide, 0.5 to 2 parts by weight of zirconium oxide, Further, a kneaded mixture may be used.

When such a component is contained, the function of adsorbing alumina ceramic balls is remarkably increased.

In addition, the diameter of the alumina ceramic balls is 0.5 mm or more and 5 mm or less, which is a suitable strength, hardness and adsorption effect.

The secondary adsorbent charging part of the present invention mainly functions to remove iron oxide, scale, and fat, and the like.

In addition, the filtration filter unit of the present invention has a tertiary mesh membrane part 530, and the tertiary membrane part has the same structure or shape as the primary membrane part.

As described above, the filtration filter unit is composed of a primary adsorbent-loaded portion between the primary mesh membrane portion and the tertiary mesh membrane portion, so that pure water can be obtained by removing the condensed water and the impurities in a tertiary manner.

In addition, the filtration filter portion of the tertiary filter structure generates a venturi effect in a minute space between alumina ceramics having high strength, such as metal, in the secondary adsorbent charged portion, It is also possible to create the effect of

The steam outlet 540 is formed with a space through which the pure steam having passed through the tertiary filter structure is discharged.

The steam withdrawal portion is connected to the steam discharge portion to discharge the treated steam to the outside of the housing.

As shown in FIGS. 1 and 6, the present invention is also characterized in that the above-mentioned filtration filter unit is formed as a cylindrical filtration filter unit, so that it can be easily replaced at the time of use, thereby providing convenience in use.

The technical feature of the present invention is that the structure of the above-described upper housing is unique.

Since the upper housing or the lower housing of the present invention is made of a metal material (especially stainless steel), when the outside temperature and the inside temperature of the housing significantly differ, condensation water may be generated in the housing.

Accordingly, the present invention is characterized in that the above-described upper housing is a double heat insulating housing formed by an outer plate 111, a vacuum layer 112, and an inner plate 113.

8, the end surface of the upper housing is composed of the outer plate 111, the vacuum layer 112, and the inner plate 113, so that even if the temperature difference between the inner and outer portions of the housing is large, It creates an effect that is not.

The outer plate and the inner plate are made of a metal material, and preferably made of stainless steel.

The present invention provides an environmentally friendly high efficiency integral steam filter having the above structure.

The present invention is a very useful invention for industries that produce, process and provide steam.

Further, the present invention is a very useful invention for a cogeneration power plant using steam, a heating system, a food processing process, a precision medicine, and a semiconductor industry.
