Description

Waste heat recovery device and cleaning water automatic filtering device for textile fabric post-processing device and exhaust gas reprocessing device using them {waste-heat recovering system and cleaning-water auto filtering system and exhaust-gas regenerative system for tenter}

The present invention relates to a waste heat recovery device and an automatic washing water filtration device used in a post-processing device of a textile fabric, and an exhaust gas reprocessing device using the same.

In the production process of textile fabrics, most of the fabrics are subjected to a precipitation process of injecting moisture, resin, chemicals, etc. into the fabric from the outside of the chamber to improve the quality of the fabric, and dehydration by mangle. In order to improve the quality of the fiber, drying and heat treatment processes are carried out while passing through a post-processing device (tenter) formed of several chambers (about 4 to 10) according to the type and output.

At the time of operation of the fiber finishing apparatus as described above, water contained in the fabric is evaporated in the drying process by the high temperature air circulated inside the chamber, and water vapor is generated. In the heat treatment process, the gas is processed by the resin and chemicals. Occurs.

Therefore, the post-processing device has a gas discharge means for discharging the hot air and the generated gas inside the chamber to the outside of the chamber by the exhaust blower in order to maintain the proper humidity inside the chamber required for fabric drying and to maintain the lower concentration limit of the explosion gas. Due to this, fresh air is introduced into the chamber through the fabric inlet passage in front of the chamber and the fabric outlet passage in the rear of the chamber to maintain the humidity and lower explosion limit concentration required for drying inside the chamber.

In this case, when cold air flows into the front and rear of the chamber, it comes into contact with the hot gas circulating in the chamber. During this process, condensation occurs in the chamber due to condensation of the high temperature water vapor in the chamber. This affects the fabric to be dried and heat treated, resulting in poor processing of the fabric.

In addition, since all the cold cold air is introduced into the entrance and exit passages of the front and rear sides of the chamber, the temperature drop occurs in the first chamber on the front side and the last chamber on the rear side that constitute the post-factory plant.

In addition, the exhaust gas and water vapor discharged through the air blower are generally discharged to the air as it is, and the exhaust gas and water vapor have a problem of energy waste in which heat is lost as it is at a high temperature. Since the gaseous substances are contained and discharged due to resins and chemicals, there is a pollution problem such as causing serious air pollution if not sufficiently purified.

In order to solve the energy waste and pollution problems in the textile fabric post-processing device, various waste heat recovery devices and exhaust gas reprocessing devices are conventionally provided, and recently, waste heat gas ashes disclosed in Korean Patent Laid-Open Publication No. 2000-30094. There is a processing device.

The above-described inventions provided up to now have a waste heat recovery device equipped with at least one heat exchanger in an exhaust pipe for discharging high temperature exhaust gas generated inside the chamber, thereby heating the air supplied into the chamber by the heat exchanger. A wet cleaning device and an air purifying device are provided at the end of the exhaust pipe passage passing through the waste heat recovery device.

According to the structure of these prior inventions, in theory, it is possible to warm the air supplied into the chamber by absorbing heat from the high temperature exhaust gas discharged from the chamber, thereby saving energy and preventing condensation inside the chamber. It is expected to solve the pollution problem by purifying pollutants contained in the exhaust gas, but practically low practicality depending on equipment cost, efficiency, maintainability, applicability and economical efficiency of waste heat recovery system. There was this.

For example, even if the heat recovery rate of the waste heat recovery device is high, if the equipment cost is high, or the maintenance of the applied device is poor and the maintenance cost is high, the application of the waste heat recovery device is difficult.

The above invention or the conventional waste heat recovery apparatus theoretically recognized the efficiency of the waste heat recovery apparatus itself, but there are various problems in applying it to the textile fabric finishing apparatus.

Most of the conventional waste heat recovery apparatus including the above-mentioned invention employs a fin or horizontal tube heat exchanger, and the exhaust gas from the textile fabric finishing apparatus is a dust of fibrous particles and resins and chemicals with high temperature water vapor. Since the gaseous material is included together, the exhaust gas is attached to the heat exchanger fin or the heat transfer surface of the heat exchanger pipe in the form of a liquid in a fin or horizontal tube heat exchanger, so that the heat exchange rate is rapidly reduced within a short period of time.

As a method of solving the heat exchange rate drop of the heat exchanger heat exchanger surface, there is a method of performing regular cleaning work on the heat exchanger heat exchanger surface or installing a cleaning device. The cleaning process is expensive due to excessive workmanship, and the fabric processing equipment, which is required to be operated continuously 24 hours a year, can not be stopped for a long time due to the operating characteristics of the steam cleaning method. It was difficult to apply.

Therefore, the most preferable method for solving the heat exchange rate decrease phenomenon of the heat exchanger heat transfer surface is to install a cleaning device capable of continuously cleaning the heat exchanger heat transfer surface even during operation of the post-processing device.

Conventionally, the vertical reciprocating type automatic washing water spraying device has been applied to the waste heat recovery apparatus of the invention using a horizontal tube heat exchanger as a washing apparatus for the heat transfer pipes installed horizontally.

This vertical reciprocating type automatic washing water spraying device is an apparatus for vertically reciprocating movable nozzles on the pipe tube plate side of the heat exchanger and continuously spraying the washing water at regular intervals on the inner wall of the heat transfer pipe.

According to the vertical reciprocating type automatic washing water spraying device, in the process of exhaust gas passing through the heat pipe, gaseous substances caused by scattering dust and resin and chemicals contained in the exhaust gas adhere to the inner wall of the heat pipe. To some extent, it was possible to prevent, but when the washing water is injected from the vertical reciprocating mobile washing water automatic spraying device with the heating pipe installed horizontally, the pressure of the washing water is applied evenly to the entire inner wall at the front side of the heating pipe, but to the rear side. In the meantime, the injection pressure is weak and the inner wall of the heat pipe cannot be washed evenly, and the washing water collects on the bottom side of the heat pipe so that the cleaning effect is very unstable and weak. Heat exchange rate of air is reduced by half Since less heat recovery server will almost never practical.

In addition, the fin or horizontal tube heat exchanger is designed to have a long heat exchanger in the longitudinal direction of the chamber in order to obtain an appropriate waste heat recovery efficiency from the exhaust gas of the post-processing device currently operating in the field, the unit chamber of approximately 3m in length When installed on the top of the fabric finishing equipment chamber, the entire waste heat recovery system should be installed with a large number of installation spaces at the top of several chambers. Therefore, the existing exhaust gas duct facility should be removed and rebuilt. It interferes with maintenance work, and causes considerable problems such as disassembling or dismantling the waste heat recovery device when replacing the unit chamber, and separate installation space is required when installing the waste heat recovery device on the side of the chamber or on the upper side of the main discharge pipe. There was a problem.

In addition, the configuration of the washing water circulation circuit applied to the exhaust gas reprocessing device having a washing water injection device for the heat transfer surface of the pre-invention, the washing water of the injection device for washing the heat transfer surface by condensing the exhaust gas passing through the heat exchanger in the condenser Bar that is configured to supply

In the current fabric post-processing process, the dry fabric processing process with little moisture content in the exhaust gas must be supplied with cold water.In other drying processes, the amount of steam discharged is approximately 300 ~ 500Kg depending on the fabric type. Considering that it is inside / h, it is very insufficient to sufficiently wash the heat transfer surface of the tubular heat exchanger even when supplying it to the washing water by condensing it all. It takes away the heat of the heat transfer surface and the exhaust gas, which lowers the heat recovery rate, and also has the disadvantage of generating a large amount of waste water due to a large amount of washing water loss.

In addition, when washing the heat transfer surface by condensing water vapor in the exhaust gas, the fugitive dust contained in the exhaust gas and the sedimentary deposits or solids formed by the gaseous substances caused by the resin and the chemicals are mixed and sprayed to clean the nozzles. Induced by the injection efficiency is lowered and the heat transfer surface contamination was a disadvantage.

The above problems of the conventional waste heat recovery apparatus are consequently low in economical and maintainability, heat recovery rate and efficiency in applying to the textile fabric finishing apparatus, so that the above-mentioned installation is hardly considered in the textile fabric finishing apparatus until now. Problems in the operation of the post-processing device, energy waste, and pollution problems are still present.

The present invention is provided to solve the problems of the waste heat recovery device or the exhaust gas reprocessing device applied to the conventional textile fabric finishing apparatus as described above,

Another purpose is to construct a plate heat exchanger type waste heat recovery device having an automatic heat cleaning surface and to use the existing exhaust gas duct facility at the top of the chamber without being removed when applied to the fiber fabric finishing devices provided to date.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The above-described present invention will be described in detail with reference to the accompanying drawings.

Figure 1 shows the configuration of an example four-chamber fabricated textile fabric finishing apparatus (tenter) to which the present invention is applied.

Textile fabric (TX) woven from the textile weaving machine is subjected to a precipitation process of injecting moisture, resin, chemicals, etc. into the fabric in the precipitation tank (ST) to improve the quality of the fiber, and then dehydration of the fabric in the mangle (MG) Then, while passing through several chambers (CH1 ~ CH4) to suit the fiber type and production amount, the drying process, the heat treatment process and the like to improve the quality of the fiber.

Figure 2 is a longitudinal cross-sectional configuration of the chamber of the fiber fabric post-processing apparatus of the above example, Figure 3 is a cross-sectional configuration of FIG.

The configuration of the chambers CH1 to CH4 is a body CM in which the outer body is insulated with the heat insulating material IS, and a fiber fabric passing through the middle portion from one side to the other side in the inner middle portion of the body CM ( On the upper and lower surfaces of TX), hundreds of hot air nozzles HN are installed to inject hot air.

The hot air nozzles (HN) are installed in several hot air distribution boxes (HD) connected to the hot air pipe (HP), the hot air pipe (HP) is heated in the hot air blower (HB) by the heater (HT) Is recycled.

On the upper side of the chambers CH1 to CH4, several gas discharge pipes GP for discharging a part of the gas (hot air) inside the chamber are installed, respectively, and the several gas discharge pipes GP are connected to one main discharge pipe GM. Is connected to, the main exhaust pipe (GM) is a configuration installed one exhaust blower (BW).

According to the chambers CH1 to CH4 having the above-described configuration, the cold air flowing into the chamber at the inlet and outlet sides of the chambers CH1 to CH4 is mixed with the hot air circulated inside the chamber and is heated by the heater HT. Heated by hot air of a proper temperature, the heated hot air is sprayed to the hot air nozzle (HN) through a hot air pipe (HP) and a hot air distribution box (HD) by a hot air blower (HB), the upper and lower hot air nozzle (HN) Fiber fabric (TX) passing through) is to be dried or heat treated.

In the process of drying or heat treating the fiber fabric TX by operating the chambers CH1 to CH4, in the drying process, water contained in the fiber fabric TX evaporates to generate water vapor, and in the heat treatment process, resin is produced. And gas generated by treatment of chemicals.

Therefore, during operation of the chambers CH1 to CH4, part of the hot air and the generated gas circulated inside the chamber are maintained in order to maintain the proper internal humidity necessary for drying the fiber fabric TX and to maintain the lower explosion limit concentration of the generated gas.

As shown in Figure 1, the fiber fabric (TX) woven from the fiber weaving machine is subjected to a precipitation process for introducing water, resin, chemicals, etc. into the fiber fabric in the settling tank (ST), and then dewatering the fiber fabric in the mangle (MG) The process is carried out, and then a drying process and a heat treatment process are performed to improve the quality of the fiber while passing through several chambers CH1 to CH4 that are operated.

In this process, the fiber fabric TX passes between the upper and lower hot air nozzles HN when passing through the inner middle portions of the chambers CH1 to CH4 that are operated, and is sprayed from the hot air nozzles HN about 150 to 220. It is dried and heat-treated by hot air having a high temperature of about ℃.

When the drying process of the fiber fabric by the chambers CH1 to CH4 is carried out, the water contained in the fiber fabric is evaporated to generate high temperature water vapor, and in the heat treatment process, gas is generated by the treatment of the resin and chemicals. .
