Odor and PLUME CONTROL SYSTEM AND OIL RECOVERY FROM DYEING TENTER USING MULTI-THROATS VENTURI SCRUBBER AND OIL FILTER}

The present invention relates to a odor and white smoke removal and oil recovery system of the dyeing tenter process using a multi-throats venturi scrubber and a composite oil filter,

More specifically, the dust and water-based odor contained in the exhaust gas generated in the dyeing tenter process are firstly removed through a multi-throats venturi scrubber, and the composite oil filter unit of the composite oil filter unit is used. Condensing the water droplets in the exhaust gas through the heat exchanger to remove oil, fume and odor remaining in the exhaust gas secondaryly while recovering the oil and to prevent the generation of white smoke from the exhaust gas discharged into the atmosphere. After removing the water droplets condensed in the demister, the dust, odor and moisture in the exhaust gas are completely removed. It relates to odor and white smoke removal and oil recovery systems that can prevent the phenomenon.

The causative agents of odor are diverse and the intensity of odor is independent, additive, synergistic, and offset. Most odor pollution is affected by weather conditions such as temperature, wind direction, and humidity as well as by odorous substances emitted from various sources. Most complaints arising from these odors are from discharge companies in industrial complexes, and most often occur in summer rather than winter.

The dyeing industry is an industry that processes fabrics. Chemicals used during dyeing and processing or substances in fabrics are volatilized by the chemicals, causing odors. The characteristics of the complex odor generated at the dyeing plant are ironing, hoarseness and burnt odors. The main contributors of individual odors are octanal and nonanal.

The odor emission process of the general textile industry includes printing, dyeing, refining, dye blending, and tenter process. The main odor emission process is tenter process.

In addition to the odor emission in the tenter process, the smoke (white smoke) discharged into the atmosphere is a representative cause of civil complaints, especially in cloudy weather or windy days.

Most of the prevention facilities for treating the gas emitted from the tenter facilities of the dyeing industry are operated by absorption (scrubber). Various softeners and antistatic agents used in the dyeing industry are discharged in the form of fine oil fumes and water droplets by the high temperature treatment of the tenter. The odors generated from these are periodically repeated according to the weather. Being the culprit of

The tenter machine emits hot white lead including moisture and various oil components while the hot air of 150 ° C. or higher dries the inside of the apparatus. The scrubber, which is a facility to prevent high temperature flue gases (white smoke), is discharged into the atmosphere with additional moisture, which causes the fine oil components and moisture in the exhaust gases to reflect light, making white smoke appear deeper. .

In addition, the working environment of the tenter process room is poor due to the exhaust gas of the tenter facility, the duct line is very serious pollution due to the oil component. As a result, the odor of exhaust gas is further increased.

In the dyeing industry, the introduction of effective prevention facilities is urgently needed due to the continuous generation of complaints from neighboring residents due to white smoke and the odor and air pollutant emission standards that are gradually strengthened. It is urgent to prepare measures to actively respond to global trends such as greenhouse gases and carbon credits.

In order to solve such a problem, Korean Patent Registration 10-1034006 (Registration date 2011.05.02) 'White smoke and environmental pollutant removal and energy recovery dryer', Republic of Korea Patent Registration 10-1261195 (Registration date 2013.04.29) 'Ten 'Turbine exhaust gas and steam purification device', Republic of Korea Patent No. 10-1206505 (Registration date 2012.11.23) has been disclosed a technology for 'tenter exhaust gas electric fume dust collector.

However, most of the technologies disclosed in the related art do not effectively remove oil fume and water droplets, and the technology for reusing oil fume is insignificant, and thus, effectively removes fine oil fume and water droplets that are the main culprit of odor generation. There is an urgent need for a technology that can block and effectively reuse oil fume.

Civil complaints were markedly reduced by removing oil fumes and odors in the exhaust gas.However, in the winter when the air temperature was low, condensation of moisture produced fine white smoke, which caused it to be mistaken for the emission of air pollutants. Complaints have been made, and in order to solve this problem, even the finely generated white smoke was completely removed to allow complete processing.

second. As the clogging phenomenon caused by the fine dust of the nozzle and the filling material installed in the front of the multiscrubber frequently occurs, a problem arises in that a large amount of time and cost is administered and maintained, and the multi-throttle venturi scrubber is solved. In addition, the configuration has been improved to remove fine dust even without nozzles and fillings.

third. The problem of shortening the life of the oil filter is caused by the fine dust from the front end of the multi scrubber.In order to solve this problem, a removable protective cloth (Liner) is installed inside the oil filter to periodically replace the oil filter. Long life can be maintained.

In addition, some improvements have been made, and the present invention has been proposed to solve such problems. The present invention provides a odor and white smoke removal and oil recovery system of a dye tenter process using a multi-throats venturi scrubber and a composite oil filter. It is about.

The exhaust gas, which has undergone the removal of fine dust and the oil removal and recovery process through the hybrid oil filter unit 70, is transferred to the heat exchanger 80 formed at one lower end of the hybrid oil filter unit 70. .

The heat exchanger 80 is formed of a cooling coil that absorbs and cools the heat of the exhaust gas, and serves to condense the water droplets in the exhaust gas by cooling the exhaust gas introduced to the heat exchanger below the dew point. .

After condensing the water droplets through the heat exchanger 80, the water droplets condensed through the demister 90 installed in the rear stage are removed.

After condensing the water droplets through the heat exchanger and removing the water droplets condensed through the demister, when the water is contained in the exhaust gas after all the processing, the exhaust gas discharged to the atmosphere and the low temperature outside air This is to prevent cloud-like white smoke from condensing moisture due to the difference in temperature between and.

The white smoke is harmless to the human body, but as white smoke is discharged through the chimney, people frequently mistake the discharge of pollutants, causing a problem of causing civil complaints.

Therefore, in the present invention, in order to prevent such a problem in advance, it is possible to completely solve the problem of white smoke generation by completely removing the moisture in the exhaust gas through the heat exchanger (80).

A demister 90 is installed at the rear end of the heat exchanger 80 to finally remove condensed water droplets discharged together with the exhaust gas.

The demister 90 is composed of a frame 901 having a circular or polygonal structure and a filter 902 in which wires are woven in a net form within the frame,

The frame 901 and the filter 902 are poly ethylene (PE), poly propylene (PP), high tem'p PP (HTPP), polyfluoro vinylidine (PVDF), co-polymer ethylene and polylene and polytetra fluoro ethylene ), PFA (Tetrafluoro ethylene and fluoro alkoxy) of any one or two or more selected from,

The thickness of the wire is 2/1000 inch to 37/1000 inch, and the porosity of the wire woven filter is 94% to 97%.

The odor, white smoke removal and oil recovery system of the dyeing tenter process using the multi-throats venturi scrubber and the composite oil filter according to the present invention is a multi-throats consisting of a plurality of horseshoe tubes. By using this method, unlike the conventional method of removing the dust through the filling, there is no problem of clogging of the filling due to the dust, and a sudden pressure difference occurs in the process of passing through the multi-throats. As dust and water-soluble odor components contained in fine dust are easily collected in the washing water, it has the advantage that effective dust and water-soluble odorous substances can be removed, and unlike the method of removing dust through the filling, nozzles and fillings Since there is no need for cleaning, the maintenance cost can be significantly reduced.

Exhaust gas and low temperature discharged to the atmosphere by condensing the water droplets contained in the exhaust gas through the complex oil filter to remove dust, oil fume and odor, and oil recovery through heat exchanger, and then removing them through the demister. The moisture is condensed by the temperature difference between the outside air and it has the advantage that it can completely block the white smoke phenomenon that looks like a cloud.

As a result, the odor and white smoke removal and oil recovery systems of the dyeing tenter process using the multi-throats venturi scrubber and the composite oil filter according to the present invention have great industrial applicability.
