Description

DESCRIPTION

Treatment device and treatment method

The invention relates to a fluidic

Treatment device, in particular

Drying device, and a treatment method with the features in the preamble of the process and

Device main claim.

From practice, tunnel dryers for textile webs are known, in the treatment chamber of which the web is moved from an inlet to an outlet linearly moving web with a gas flow. Furthermore, drum dryers are known in which the web is placed on a rotating and heated drum.

It is an object of the present invention to provide a

show improved treatment technique.

The invention solves this problem with the features in the method and device main claim.

The claimed fluidic treatment technique, i. the treatment device and the treatment method have various advantages. This applies in particular to the preferred embodiment as a drying device and

Drying process.

By the breakdown of the treatment chamber in a plurality of one above the other and next to each other and preferably stationary arranged and traversed by the web

Chamber areas can make the treatment facility very compact and efficient. In the

Chamber regions, the web can each be unilaterally with a gas, in particular air, flowed through and flowed through. The chamber areas are each delimited from each other and are penetrated by the web or run through. Within the treatment chamber, the web along its trajectory by means of a

Guiding device, preferably by means of a belt-like and gas-permeable conveying, guided. The

Gas flow can move the web through the conveyor

hold and fix it permanently.

The treatment device can in particular

cube-shaped and upright housing have. The floor space requirement is lower than with long tunnel dryers. In addition, the efficiency of the

fluidic treatment, especially drying of the

Web with a gas flow, preferably one

Air flow can be increased. It is also favorable that for purposes of maintenance and inspection, etc. the

Functional areas of the treatment facility are easily accessible from the outside.

An inventive concept of the invention provides that the running web is guided in the treatment chamber in an upward and downward movement path. The trajectory is preferably formed as an upright loop, which may be present individually or multiple times. This is for an efficient flow through the web with the treatment, in particular drying, provided gas advantage. In particular, in connection with an arrangement of several

Chamber areas one above the other and next to each other

aerodynamic, energetic and

treatment advantages. Particularly favorable is an arrangement of the chamber areas in a chamber matrix with several, preferably two, columns next to each other and with several rows one above the other. At the top of this chamber matrix can be a central, connecting

Be arranged chamber area. This chamber area arrangement is in particular for

Generation of a circulating flow through the web in the respective chamber area advantageous. In addition, a cross chamber counterflow of the treatment gas can be achieved, which is directed against the direction of the web. This allows an adaptation of the

Gas air conditioning. In particular, the moisture content in the counterflow from the outlet to the inlet may increase. In a drying process, the moisture content of the web and the gas flow can thereby optimally

be matched.

The chamber areas are e.g. separated by Scot. They are interspersed approximately in the middle of the web. Due to the chamber-separated recirculation flow, the fluidic and climatic conditions in the respective chamber area can be optimally adapted to the local condition of the material web. This can e.g. the flow velocity and / or the

Temperature and / or the moisture content of the gas flow.

In a further independent idea of the invention it is provided that the inlet and the outlet of the web are arranged at the bottom of the treatment device. Preferably, they are located at the bottom of

Treatment chamber. The web can enter here in upright, especially vertical extent and

escape. This arrangement has energy advantages.

Heat losses and leakage of hot gas from the inlet and outlet can be reduced. this concerns

in particular the discharge of hot gas from the outlet with the moving web. Due to the natural thermals of the treatment chamber located and preferably heated treatment gas results in a natural gas lock, in particular airlock. In addition, the chamber regions located at the inlet and outlet and preferably located far below can be tempered lower than the further chamber regions which adjoin the chamber matrix at the top. Another advantage of the chamber matrix and the arrangement of several mutually delimited chamber areas

one above the other consists of a clean segregation of the hot and cooler gas flows, in particular

Recirculating flows. The treatment process, in particular the drying process, can be better and more precisely controlled and, if necessary, regulated when using an appropriate sensor system. Due to the lowered temperature in the lower chamber areas additional energy can be saved. In addition, the web can already cool in the area of the outlet and with low temperature from the

Emerge treatment device. As a result, less energy is discharged with the web into the environment.

The chamber areas are separated by bulkheads

separated. The bulkhead can be partly gas-tight and partially gas-permeable. In particular, an upright and substantially gas-tight bulkhead may be central and between the columns of the chamber matrix

be arranged. As a result, the preferably horizontal recirculation flows can be separated from each other in the adjoining chamber areas. Between the superimposed rows of

Chamber areas in the chamber matrix gas-permeable bulkheads can be arranged horizontally. This allows a gas passage for said countercurrent against the

Running direction and along the path of movement of the web.

Also advantageous is a nozzle arrangement in several, preferably all chamber areas, which is arranged on each side of the web along its trajectory or on both sides. The nozzle arrangement is especially advantageous for the recirculation flow. A variable design of the nozzle assembly allows a fluidic adaptation to the respective

Treatment requirements in the different

Chamber regions. The nozzle assembly may be designed so that there are no lint and fibers in larger

Can accumulate circumference. The web itself can act as a filter. The lint is conveyed out again via the web. The remaining lint collects at the bottom of the treatment chamber. However, these do not affect the performance of the treatment facility,

in particular drying device, and can be removed during the usual cleaning cycles, in particular

be sucked out. In the nozzle arrangement, the nozzle slots and in particular their width, can be changed. Progressive nozzle slots allow optimal adjustment of the flow and pressure conditions to the individual

Treatment, in particular drying process steps. This concerns e.g. the intense flow and heating of the web and the possibly contained therein

Moisture, evaporation of surface water and possibly of the core water. If necessary, a fluffiness and a volume of the web can be generated and adjusted.

The claimed treatment - in particular

Drying technology is particularly suitable for moist

Webs of textile fiber materials, in particular nonwoven fibrous webs. The drying device can be used for drying a nonwoven fabric, which comes from an upstream hydroentanglement. Here, the heat and moisture or the water of the exhaust gas, in particular the exhaust air,

be regenerated and possibly recycled in a cycle. That in the humid air of the

Drying device contained water can from the Gas flow deposited and the

Water jet hardening device to be supplied. In this case, a regeneration, e.g. a cleaning and possibly a temperature, take place. As a result, the water consumption in the solidification and drying of the

Nonwoven nonwoven fabrics are reduced. In addition, the energy consumption can be reduced.

The treatment, in particular drying device may be part of a fiber treatment plant. The

dried web can after leaving the

The invention relates to a treatment device (1) and a treatment method for a running material web (2). Preferably, it is a drying device (1) and a drying method for drying a moist web (2). The invention further relates to a fiber treatment plant (3) with such Treatment facility (1) and a corresponding plant-spanning process.

Hereinafter, a drying device (1) and a drying method will be described. The features also apply to another type of

Treatment device (1) and the treatment method.

The web (2) can be dry or moist. It can consist of any materials. In the illustrated and preferred embodiments, the e.g. moist web (2) made of a textile fiber material,

in particular a nonwoven nonwoven fabric. The damp

Web (2) is advanced within the drying device (1) and is doing with a gas flow,

in particular an air flow, dried. Alternatively, instead of air, another gas can be used. The web (2) is band-shaped, with their

Width is significantly larger than the thickness.

The drying device (1) is shown in Figure 1 and 2 in an external view and perspective view from the front and from behind. Figure 3 shows a front view and Figure 4 is a folded side view of

Drying device (1) of Figure 1 and 2. The

Drying device (1) has a housing (8) with an inner treatment chamber, in particular

Drying chamber (14), with an inlet (10) and an outlet (11) for moving in the direction (17)

Web (2) on.

The housing (8) has a preferably rectangular,

especially cube-shaped, shape. The base of the housing (8) may be the base of usual

Drum dryers correspond. The drying device

arranged. It has one or more accesses (9) on one or more side walls, e.g. Doors or flaps, for the internal drying chamber (14) and their

subsequently explained chamber areas (20-24).

As illustrated in particular Figures 6 and 7, the treatment chamber (14) a plurality of superimposed and

juxtaposed stationary chamber areas (20-

24), which are traversed by the web (2). The running web (2) is thereby in the treatment chamber (14) in an upward and downward direction

Movement path (16) led. The movement path (16) is preferably formed as an upright loop, the two upright, in particular vertical, track sections and an upper lying, in particular horizontal,

Railway section has. The inlet (10) and the outlet (11) for the web (2) are arranged at the bottom of the treatment device (1), in particular the drying chamber (14). Preferably, they are located at the bottom of the drying chamber (14). The web (2) occurs here with an upright, especially vertical

Extension and movement direction on and off. Of the

Inlet (10) and spout (11) are e.g. when

slit-like openings formed in the chamber bottom.

The web (2) is fed via a conveyor (30) to the inlet (10). At the outlet (11) it is taken over by a further conveyor (31) and transported away. The conveying means (30, 31) are e.g. as encircling

formed horizontal conveyor belts, where they may alternatively have any other shape and design. Within the drying chamber (14), the material web (2) is guided along the loop-like movement path (16) by means of a guide device (15). The Guide device can be designed in different ways. In the exemplary embodiment shown, it is formed by a circumferential flexurally elastic conveying means (28), for example an endless conveyor belt, which is set in circulating motion by means of a suitable drive (29 '). The conveyor (28) is gas-permeable and has, for example, a grid or

Fabric structure with openings for gas passage on. The conveyor (28) receives at the inlet (10) the web (2) on one side, in particular on the outside, takes them along and transports them along the movement path (16) to the outlet (11). The web (2) is doing by

Blasdruck a gas flow in the frictional engagement on the conveyor (28) held and taken away. The unilaterally impinging gas flow can hold and fix the web (2) on the conveyor (28) in permanent contact, in particular on the upright sections of the loop-like

Trajectory (16). The conveyor (28) is

preferably driven at a rotational speed which corresponds to the feed and discharge of the web (2).

The guide device (15) also has several

Deflections (29), e.g. rotating and possibly driven guide rollers, for the conveyor (28) and the am

Conveyor (28) adjacent web (2) on. Two deflections (29) are at the top of the

Drying chamber (14) with distance next to each other

arranged. They define the deflection points of the

Movement path (16) and are preferably at the same height and vertically above the inlet (10) and the outlet (11). One or more of the deflections (29) in the upper region of the drying chamber (14) may have a

Holding device (29 ") for the web (2) and possibly the conveying means (28) .The holding device (29") may be formed for example as a suction device. The conveyor (28) is down from the

Drying chamber (14) and the housing (8) out and over other lower deflections (29) and a drive (29 ') together with clamping means. Here is also a sensor for

Band and motion detection arranged. About the

Deflectors (29), the conveyor (28) is guided in a substantially rectangular and closed orbit.

In the drying chamber (14), according to FIGS. 5 to 7, at least part of the chamber regions (20-24) arranged one above the other and next to one another are arranged in a chamber matrix. In the shown and preferred

Embodiment, the chamber matrix (2) has two columns or columns of juxtaposed chamber areas (20-23 ') and two or more rows, e.g. three rows of superimposed chamber areas (20-23 ') on. The chamber matrix is preferably formed uniformly, wherein the respectively adjacent chamber regions (20-23 ') are arranged and aligned in line with one another and one above the other. FIG. 6 illustrates this

center symmetrical arrangement. At the top, the drying chamber (14) has a central chamber area (24) extending over both columns or columns of

Chamber regions (20,21,21 'and 22,23,23') and connects them in the transverse direction. The central one

Chamber region (24) is horizontal, in particular horizontal, arranged. As Figure 5 illustrates, the chamber areas (20-24) extend across the depth of the drying chamber (14).

In the embodiment shown are seven

Chamber areas (20-24) available. According to FIG. 6, three chamber regions (20, 21, 21 ') are provided in the left-hand column.

arranged one above the other. In the right column are three chamber areas (22,23,23 ') in the vertical over each other arranged. In the three rows are the

Chamber regions (20, 22) and (21,23) and (21 ', 23') in each case in the horizontal side by side and arranged center-symmetrically. The chamber areas (20-23 ') preferably each have the same size.

The chamber areas (20-24) are passed through by the web (2) in succession. The chamber areas arranged one above the other in the two columns or columns

(20,21,21 ') and (22,23,23') are each traversed by an upright movement section of the movement path (16). The lying upper chamber portion (24) is penetrated by a horizontal portion of the trajectory. In the upper chamber area (24) are also the

Deflections (29). In the embodiment shown, the loop-shaped movement path (16) has a downwardly open U-shape. The chamber areas (20-24) have one

cuboid shape and are formed as cavities. They are penetrated by the web (2) or its trajectory (16) in about the center. The web (2) or

Trajectory (16) divides the chamber areas (20-23 ') respectively in an outer peripheral portion and an inner or central portion. The chamber areas (20-24) are separated by bulkheads or walls (25, 26). The bulkheads (25, 26) can be designed differently. Between the columns or columns of the chamber matrix and the respectively superimposed chamber regions (20-23 ') an upright and preferably central bulkhead (25) is arranged. It is essentially gas-tight and separates the

side and left and right chamber areas (20,22), (21,23) and (21 ', 23') fluidly from each other. Between the rows of chamber regions (20-24) lying one above the other in the chamber matrix, bulkheads (26) are arranged horizontally. The bulkheads or Trays (26) may on the one hand have a passage opening for the movement path (16) or the material web (2). You can also have another bottom opening, the

in places enable an upright passage of gas. In particular, the treatment gas can flow from bottom to top due to the thermal.

The treatment device (1) has a

Ventilation device (18) for generating a gas flow in the drying chamber (14). The

Treatment device (1) may further include a

Have heating device (19) for heating the treatment gas. The aeration device (18) is designed such that it in the chamber areas (20-24) each have a

Circulation generates flow (32) of the gas. The circulation flow (32) is directed on one side against and through the web (2) and can penetrate them. The

Flow direction can be directed transversely or obliquely to the movement path (16). The circulating flow (32) is, as shown in FIGS. 5 and 6, aligned in the chamber regions (20-23 ') arranged in the chamber matrix, in particular horizontally. In the horizontal chamber region (24), the circulation flow (32) upright, in particular vertically aligned.

The ventilation device (18) is also such

in that it forms between the chamber regions (20-24) a countercurrent (33) of the treatment gas directed counter to the running direction (17) of the material web (2)

generated. The counterflow (33) is directed from the outlet (11) to the inlet (10). It extends along the movement path (16) in the drying chamber (14). The

Counterflow (33) has a moisture content increasing over the flow path. At the inlet (10), the incoming web (2) has the maximum moisture content. Here, by the counterflow (33), the treatment gas also has a high

Saturation of moisture, especially water. In

Running direction (17) of the web (2) are the

Gas flows, in particular recirculation flows (32) and the counterflow (33) and the web (2) increasingly dry. At the outlet (11), the web (2) and the gas flows (32,33) have the lowest degree of moisture.

The ventilation device (18) has a supply (12) for fresh gas and a discharge (13) for exhaust gas, each with a blower (34 '). The fresh gas is fed with positive pressure in the drying chamber (14) and the exhaust gas with

Vacuum sucked out of the drying chamber (14).

In a drying process, the fresh gas has the

lowest and the exhaust the highest moisture content. The supply (12) can be at any suitable point of

Drying chamber (14) may be arranged. It is located e.g. at the bottom of the chamber and opens at the directly above the outlet (11) arranged right chamber area (22).

The discharge (13) is also at the bottom of the

Drying chamber (14), preferably arranged at the bottom of the chamber. It empties e.g. at the right above the inlet (10) arranged left chamber portion (20). The

Chamber regions (20, 22) are the lower chamber regions in the chamber matrix.

Through the spatial separation and distance as well as the

Pressure differences of the supply (12) and discharge (13), the counter-flow (33) is generated in the drying chamber (14). The counter-flow (33) flows along the movement path (16) and through the successive chamber regions (20-24). The central bulkhead (25) and the gas-tight bottom bulkhead (26) of the upper chamber region (24) are cheap and force the counterflow (33) in the desired path.

The ventilation device (18) has a plurality of blowers (34), each associated with a chamber area (20-23 '). Optionally, a fan (34) may be present or absent at the upper chamber portion (24). The fans (34) are preferably arranged on the rear side of the housing (18) and on the rear wall there. They are preferably designed as circulating air blowers, which in the respective

Circulation chamber (20-24) circulating treatment gas and produce the said horizontal or horizontal recirculation flow (32). They suck, for example axially and blow out radially. The holding device (29 "), in particular

Suction device, at the or the upper deflector (s) (29) may be connected to the suction side of the upper fan.

As Figure 5 illustrates in the sectional plan view, the web (2) extends only over part of the

Chamber area depth, being between the back wall of

Housing (8) and the adjacent edge of the web (2) or the movement path (16) an overflow channel (27) with a partition wall (27 ') remains. The at the partition (27 ') opening blower (34) suck that in the central

Subarea between bulkhead (25) and web (2)

located treatment gas to the rear and blow it laterally through the overflow channel (27) in the peripheral portion. From here, the treatment gas passes through the web (2) back into the central portion. The web (2) extends between the rear partition (27 ') and the gas-tight front wall of the

respective chamber area (20-24). The chamber front wall can be distanced from the front wall of the housing (8) according to FIG. The heating device (19) has a plurality of heating modules (39) which are each assigned to a chamber region (20-24). In the upper chamber area (24), a heating module (39) may be optional or absent. The heating modules (39) can be designed in the same way and operated with any suitable heating media. In the exemplary embodiment shown, the heating modules (39) burn a heating gas or a liquid heating means and have for this purpose in each case a heating device (40) located in the respective chamber region (20-24), eg a burner, and an external connection (41), eg a gas connection, on. The heaters (40) are preferably located in front of the

respective blowers (34). The fans (34) and / or the heating modules (39) are each arranged centrally and close to the central bulkhead (25). The respective negative pressure zones and / or

Heating zones of the chamber areas (20-24) are located

within the loop-shaped movement path (16) or web (2). The overpressure zones are each outside of said path of movement (16) or web (2).

arranged.

The of the web (2) in the running direction (17)

continuous chamber areas (20-24) can

different climatic conditions and / or

Have flow conditions of the respective gas flow (32,33). The respective heating modules (39) and blower (34) can by means of a control, not shown

be controlled and adjusted differently.

In particular, the chamber area (20-24)

different temperatures and possibly different

Have moisture levels of the treatment gas. Out

For thermal reasons, the hot treatment gas rises anyway in the superimposed chamber areas upwards. In the lower chamber areas (20,22) at the inlet (10) and outlet (11), the gas flow is lower tempered as in the overlying chamber areas (21,21 ', 23, 23', 24).

According to FIGS. 6 to 8, the ventilation device (18) has a nozzle arrangement (35) for the gas flow, in particular the circulation flow (32), in several chamber regions (20-24) on the material web (2). The

Nozzle arrangement (35) can be made variable. It consists e.g. of a plurality of substantially triangular in cross-section, strip-like nozzle bodies (36,37), which are arranged at a distance next to each other or one above the other and each form a nozzle opening (38). The nozzle assembly (35) includes e.g. in the chamber areas (20-24) each have a number of several outer

Nozzle bodies (36) in the flow direction in front of the web (2) and a number of several inner nozzle bodies (37) in the flow direction behind the web (2). FIG. 8 clarifies this arrangement. Due to the triangular shape of the nozzle bodies (36, 37), the nozzle regions or flow regions formed between them are convergent and in each case concentrate the incoming gas flow toward the narrow, slot-like nozzle opening (38).

The nozzle bodies (36, 37) extend according to FIGS. 6 and 7 transversely to the running direction (17) of the material web (2) and in the depth direction of the drying chamber (14). The nozzle bodies (36, 37) are each held at their ends in a frame or frame. This arrangement can be movable or adjustable. This allows the width of the

Nozzle openings (38) in the running direction (17) and possibly the number of lined in a chamber area nozzle body (36,37) can be varied. The nozzle arrangement (35) extends at least regionally, preferably circumferentially, along the movement path (16) and through passage openings in the horizontal bulkheads (26) in the chamber matrix

located chamber areas (20-23 ') and by upright bulkhead of the upper chamber portion (24). The treatment device (1), in particular

Drying device, may be a single device. It may alternatively be connected to a plurality of upstream and / or downstream devices.

In particular, the drying device (1) with a preceding water-jet solidification device (6) can form a functional and possibly also structural unit. Furthermore, alternatively or additionally, the
