Description
Technical Field
The invention relates to a fabric cloth shaping device, in particular to a high-intelligent self-cleaning environment-friendly energy-saving shaping dryer.
Background
The setting machine is the key equipment of weaving printing and dyeing after-treatment. The existing setting machine adopts a burner to directly heat, and the smoke in the drying room is discharged to the outside through a pipeline for centralized treatment. The processing mode is dry in hot air, uneven in temperature, low in quality of the fabric cloth after being shaped, especially sensitive fabric, and can supplement carbon dioxide, water and oxygen into a drying room of the shaping machine after being directly heated. In addition, because the temperature is high in the cloth heat setting process, a large amount of high-temperature gas is generated in the baking oven of the setting machine, the high-temperature gas contains organic oil, dye auxiliaries, lubricating oil, fiber particles and other pollutants, and each setting machine generally discharges 150-250 mg/m3 of particles and 40-80 mg/m3 of oil smoke; the main components of the compound are aldehyde, ketone, hydrocarbon, fatty acid, alcohol, ester, lactone, heterocyclic compound and aromatic compound. The oil mist waste gas volatilized when the setting machine works is inhaled into a human body to directly damage the respiratory tract mucosa, has a certain stimulation effect on the respiratory tract and the lung of the human body, reduces the immunologic function of the human body, causes the symptoms of choking, chest distress and short breath, the contraction of the air passage and the increase of the respiratory resistance, and therefore, the pollution problem caused by the waste gas emission of the setting machine becomes more and more acute.
The waste gas treatment of the setting machine generally comprises a water spraying treatment process and an electrostatic treatment process.
The principle of the electrostatic treatment process is as follows: the dust particles are charged by a strong electric field, and when particles with positive/negative charges pass through the dust removing electrode, the particles are respectively adsorbed by the negative/positive electrode plates, so that the dust removing purpose is achieved. However, the electrostatic treatment process has the following disadvantages: a. dust must be filtered and then purified, and a multi-stage mechanical filter screen is usually selected; because the waste gas of the setting machine contains a large amount of fibers and oil stains, the workload of cleaning and maintenance is increased; b. the waste gas temperature of the setting machine is sometimes as high as 180-200 ℃, even under the working condition of low waste gas temperature, the electrostatic purifier is difficult to avoid firing, and at the moment, if the system has no safe and reliable protection measures, the electrostatic purifier is usually scrapped due to a fire disaster; c. the electrostatic treatment has relatively high requirements on the process and the structure of the purification equipment, so the use cost is relatively high.
The working principle of the water spraying treatment process is as follows: high-temperature waste gas generated by the forming machine enters a waste gas purifier, enters a spraying area after being subjected to slow flow, uniform flow and diffusion in a flow guide area, the flue gas is in turbulent flow contact with high-pressure water mist in the spraying area, and harmful gas, fibers, dust and oil mist in the waste gas are collected by the water mist and then flow into an oil-water separation water tank through a water outlet at the bottom of the purifier; the gas after being sprayed, purified and cooled enters a dehydration area from a spraying area, and the dehydrated clean gas is exhausted into the atmosphere from the top of the purifier through an exhaust pipeline. However, water spraying treatment easily causes water pollution, secondary pollution to the environment is easily caused, the treatment efficiency is low, and the use cost is high.
At present, also there is the equipment that is used for the high temperature waste gas recovery that can produce the forming machine to recycle on the market, and it collects the back through the high temperature waste gas that the pipeline produced the forming machine, through the mode combustion exhaust gas of burning, with the clean waste gas discharge after the burning to in the heat energy cyclic utilization who produces the burning the forming machine. However, the device can not directly treat the high-temperature waste gas generated by the setting machine, the high-temperature waste gas still easily causes the accumulated oil in the pipeline after passing through the pipeline, the fire disaster is caused without cleaning for a long time, and the safety factor is low.
