Definitions

  • the present invention pertains to a waste heat recovering device, cleaning-water auto-filtering device, and exhaust gas regenerating device for tenters.
  • the textile in a process of producing textile, the textile is dipped in a mixture of water, resin, and chemicals provided outside chambers of a tenter (settling step), dehydrated by a mangle (dehydrating step), and dried and heat-treated using a tenter comprising chambers (four to ten in number) (drying and heat-treating step) so as to improve its quality.
  • the number of the chambers depends on a kind of fiber and an amount of the textile.
  • a gas discharging unit for discharging high temperature air and noxious gas by an air blower so as to desirably maintain humidity in the chambers and to prevent explosion of the gas.
  • the gas discharging unit functions to feed fresh air through a textile inlet and outlet of a first and end chamber, respectively, positioned at a front and rear of the tenter, respectively, into the chambers.
  • the cold fresh air fed into the chamber comes into contact with the high temperature gas in the chambers to condense the high temperature steam to form condensate on inside walls of the chambers, thus negatively affecting the drying and heat-treating step of the textile.
  • the first and end chambers are lower in temperature than other chambers located between the first chamber and the end chamber.
  • the gas and steam are discharged by the air blower to the atmosphere without treatment of the gas and steam, so heat contained in the high temperature gas and steam is undesirably wasted and serious atmospheric pollution is caused by the volatilized chemicals and dust consisting of yarn dregs.
  • the waste heat recovering device and exhaust gas regenerating device disclosed in Korean Pat. Laid-Open Publication No. 2000-30094.
  • the conventional waste heat recovering device including one or more heat exchangers is connected to pipes for discharging the high temperature gas, and a rinsing device or an air purifying device is installed at an end of the pipes to purify the gas passing through the waste heat recovering device. At this time, the cold fresh air is fed into the chambers after being heated by the heat exchangers.
  • the conventional waste heat recovering device has high heat- exchanging efficiency, but has practical disadvantages in being used as an auxiliary device of the tenter.
  • the conventional waste heat recovering device uses a pin type or horizontal pipe type of heat exchanger, and gas exhausted from the tenter carries the high temperature steam, dust such as yarn dregs, and the resin and chemicals, so the exhaust gas is easily attached to heat-exchanging pins or pipes of the heat exchanger as a thick residue, thereby rapidly reducing the heat exchange efficiency of the waste heat recovering device.
  • a heat transfer surface of the heat exchanger may be regularly cleaned or a separate cleaning unit may be installed in the waste heat recovering device so as to avoid rapid reduction of the heat exchange efficiency of the heat exchanger.
  • a steam cleaning process widely used as a cleaning process of waste heat recovering devices, because cleaning cost of the heat exchanger is excessively high due to required high manpower, and it is disadvantageous to stop operation of the tenter, traditionally operated continuously, in order to clean the heat exchanger. Accordingly, it is necessary to install the cleaning unit in the waste heat recovering device so as to effectively avoid rapid reduction of the heat exchange efficiency of the heat exchanger and continuously clean the heat transfer surface of the heat exchanger without stopping the operation of the tenter.
  • the vertically reciprocating cleaning-water auto-jetting device is provided with vertically reciprocating nozzles facing pipes of the heat exchanger, and periodically jets cleaning water into inside walls of the pipes. If the vertically reciprocating cleaning- ater auto-jetting device is used to clean the heat exchanger, it is expected to prevent the thick residue formed by the contaminated gas containing the yarn dregs, the resin and chemicals from attaching to the inner walls of the pipes of the heat exchanger.
  • the cleaning water is jetted all over the front inner walls of the pipes of the heat exchanger, but is only partially jetted to the rear inner walls, and gathers on a bottom of the pipes and mostly cleans the bottom of the pipes instead of the rear inner walls, thus incompletely cleaning the pipes and not sufficiently improving the heat exchange efficiency of the heat exchanger, thereby having limited practical use.
  • the pin type or horizontal pipe type of heat exchanger is longitudinally installed outside the chambers constituting the tenter so as to obtain desired heat recovery efficiency from the exhaust gas from the tenter. Therefore, when the heat exchanger including chambers each having a length of about 3 m is installed on upper sides of the chambers of the tenter, an exhaust gas duct installed on the chambers is disassembled and then reconstructed because the waste heat recovering device occupies a large space on the upper sides of the chambers while occupying a large area, and the waste heat recovering device is cumbersomely disassembled and reconstructed during repairing or changing the chambers. Further, a size of the tenter is undesirably increased when the waste heat recovering device is installed on the tenter of the chambers or on an upper side of a main discharge pipe connected to the tenter.
  • the cleaning water used in an exhaust gas regenerating device provided with a cleaning- water jetting unit is obtained by condensing the exhaust gas passing through the heat exchanger with the use of a condenser, but an amount of the cleaning water thus obtained is too small to sufficiently wash the heat transfer surface of the heat exchanger.
  • the above conventional waste heat recovering device is poor in terms of economic efficiency, heat recovery, and ease of its maintenance and repair, so it is not preferable to commercialize the conventional waste heat recovering device for application to tenters. Furthermore, there remain problems such as energy wastage and atmospheric pollution in using the tenter adopting the conventional waste heat recovering device.
