Generally, the processing of fabric fabrics such as woven fabrics or knitted fabrics includes a heat setting process performed as a pre-dyeing process, a drying process performed as a post-dyeing process, And a tenter machine is mainly used as a device for carrying out such a process.

A conventional tenter device includes a chamber having a fabric fabric horizontally passing through the upper space and having fabric fabric inlet and fabric fabric outlet at the upstream side and the downstream end of the fabric in the conveying direction; A hot air generating duct disposed in a lower space of the chamber; A heater coupled to one side of the hot air generating duct; A hot air supply duct connected to the other side of the hot air generating duct and extending upward and having a plurality of hot air outlets opened on the upper side toward the one side of the hot air generating duct; An upper and a lower hot air spray nozzle coupled to a surface of the nozzle body facing the fabric end, and having a plurality of nozzle holes; The air in the chamber is sucked through the heater and the hot air generating duct to blow air into the hot air blowing nozzle through the hot air supply duct to blow hot air through the nozzle hole of the hot air blowing nozzle, And an air blower for blowing air to the upper and lower surfaces of the blower.

The entire length of the chamber is determined in accordance with the feed rate and processing conditions in the processing of the fabric raw material. The chamber is constructed by connecting a plurality of unit chambers having a length equal to the entire length. The cloth fabric inlet and the fabric fabric outlet are respectively provided in upper and lower end unit chambers provided at upper and lower ends of the unit chambers.

When performing the heat setting process, the drying process and the shrinking process by the conventional tenter device, when the blower and the heater are operated while the fabric is transferred, air in the chamber is sucked into the hot air generating duct through the heater by the blower, The heated air is heated by heat exchange with the heater to generate hot air of about 180 to 220 ° C. The generated hot air is supplied to the inside of the hot air spray nozzle through the hot air supply duct by the blower.

The hot air supplied to the inside of the hot air jetting nozzle is sprayed on the upper and lower surfaces of the fabric through a plurality of nozzle holes formed in the nozzle plate of the hot air jetting nozzle to perform a heat setting process, a drying process or a shrinking process.

Prior art related to the hot air supply of existing tenter machines is disclosed in Korean Patent Registration No. 10-0613898 entitled " Hot Air Supply and Distribution Structure of Tenter Machine "(Registered Date: August 10, 2006) A circulation fan for forcedly circulating and supplying hot air to the air guide duct side, a circulation fan for circulating and supplying the hot air to the air guide duct side, a circulation fan for circulating the hot air to the air guide duct side, A duct member for guiding the air recovered in the chamber to the circulating fan side and a heating member for reheating air to be guided through the duct member, wherein the air guide duct comprises a circulation fan An upper branch duct and a lower branch duct for branching hot air forcedly transferred and guided to the upper and lower hot air blowing ducts, respectively, Ducts is to achieve a guidance channel of the same shape and length interconnected by the intermediate partition wall.

However, the hot air in the existing tenter is exhausted to the outside after performing the fiber drying process. When the discharged gas is discharged to the outside in a state containing foreign substances such as tar buried in the fibers, It is a cause of pollution, so it is filtered through filtration means and then discharged to the atmosphere, but there is a disadvantage that the thermal energy is discarded as it is in the atmosphere.

Another prior art for solving this problem is disclosed in Korean Patent Registration No. 10-1211375 entitled " Tentacle Exhaust Gas Waste Heat Recovery System "(Registered on December 16, 2012) A first duct connected to the tenter chamber to induce and discharge a high temperature exhaust gas containing tar generated after drying of the fiber fabric; A first branch duct and a second branch duct integrally connected to a root of the first duct to divide the first duct into two; A plurality of first heat exchanging means installed in each of the branch ducts so as to collect tar on the surface by fusion of tar contained in the exhaust gas through heat exchange with high temperature exhaust gas to collect tar; Carbonizing means disposed between the respective first heat exchanging means and carbonizing the tar together with the tar adhered to the surface of the first heat exchanging means by applying heat to the surface while fusing the tar to the surface; A second duct connected to each of the spray tubes so as to supply heat of hot air to the spray tubes of the tenter chamber by replacing the heat collected by the first heat exchanger with the second heat exchange means; And the first heat exchange means included in the branch duct of any one of the first and second branch ducts is operated to collect the tar, the other branch duct blocks the exhaust gas at a high temperature and at the same time operates only the carbonization means, And a valve disposed on an inlet side of the first and second branch ducts so as to be carbonized so as to intermittently control the hot air.

However, in the conventional waste heat recovery system for a tenter, coal tar is carbonized by collecting the tar contained in the exhaust gas and simultaneously heating the coal tar. However, even if the tar component having high viscosity is carbonized in the state of being adhered to the filter, There is a possibility that the filter may be blocked easily by blocking the filter. As a result, the exhaust gas may not be discharged and may be stagnated or flow back to the tenter side, which may cause the tenterge to explode.

In order to solve this problem, it is troublesome to clean the filter after it is drawn out of the duct frequently, and there is a disadvantage that the tenter unit must be stopped during the cleaning operation of the filter.
