Description
Technical Field
The utility model relates to a waste gas treatment technical field especially relates to an oil smoke exhaust treatment device of oil hot pepper goods processing industry.
Background
In China, chili sauce is taken as the most common seasoning and is deeply loved by people. Wherein, in the production process of the chili sauce prepared from the oil, the chili is required to be fried in high-temperature hot oil, so a great deal of oil smoke is generated, the particle size of oil smoke fine particles is between 0.01 and 1 micron, and the concentration can reach 200mg/m 3. Meanwhile, a large amount of volatile or semi-volatile organic compounds (VOCs, mainly pollutants such as aldehydes, ketones, hydrocarbons, fatty acids, alcohols, aromatic compounds, esters, lactones, heterocyclic compounds and the like) are generated during frying, and influence is caused on the quality of the surrounding air environment. Especially, peculiar smell with low stimulating threshold value such as capsaicin and the like generates stronger sensitive reaction to the smell of human bodies, and residents around enterprises are deeply bitter and strongly react, so that the peculiar smell can be discharged only through thorough treatment.
The oil fume generated in the oil pepper production is complex in components and is accompanied by fire fume, and pollutants such as dust, SO2, NOX and the like exist in the fire fume. The main oil smoke treatment technologies at present are as follows:
① liquid washing method, liquid washing method clean principle is that the oil fume contacts with absorption liquid through liquid distribution device, make them produce and mix and absorb, condense and change the phase, transfer the particulate matter in the oil fume from the gaseous phase to the liquid phase and remove, the liquid washing method can also remove SO2, CO2, NOx etc. waste gas in the fire fume while removing the solid, liquid particulate matter in the oil fume.
② filtering method, the principle of the filtering method is that when the oil fume passes through the purifier, the particulate matter in the oil fume is removed by being intercepted by the filtering material, grid, etc. in the purifier due to diffusion and collision.
③ static method, the purifying principle of the static method is that when oil smoke passes through high voltage electric field, the particles in the oil smoke are charged and move to the dust collector under the action of the electric field force and are deposited to be removed, the removing position of solid and liquid particles in the oil smoke is higher at the beginning, the pressure drop is smaller, but the oil smoke has viscosity, and the oil smoke is easy to be bonded and deposited on electrodes during operation, which affects the removing rate, causes the cleaning difficulty of dust collection, increases the maintenance workload, and in addition, the removing effect of the static method to gaseous pollutants is not good.
④ catalytic method, the principle of catalytic purification for treating oil fume is similar to that of treating organic waste gas in industry, that is, oil fume is passed through catalyst at a certain temperature in cooking process, under the action of catalyst, the particulate matter and gaseous pollutant in oil fume are oxidized, burned and converted into CO2 and water vapor, eliminating pollution and stink, achieving the purpose of treatment.
Therefore, any single treatment method has the problems of unstable removal effect, complex maintenance, poor system operation stability and the like. The main reasons are:
① the oil pepper product industry has high temperature of processing oil smoke exhaust gas, the temperature of the oil smoke generated in the frying process is higher than 70 ℃, the heat diffusion is fast, and in order to completely collect the oil smoke, a large amount of air is often sucked, which causes a large load for the end treatment.
② the oil pepper product industry has the processing oil smoke exhaust gas different from kitchen oil smoke, and the exhaust gas is continuously discharged, the discharge time is long, the discharge amount is large, and the stability of the continuous work of the processing equipment is not enough.
③ the oil-smoke waste gas generated by processing oil-pepper product industry is accompanied by fire smoke, dust particles in the fire smoke are bonded with oil-smoke particles, and pipelines and treatment equipment are easy to block, and the long-term stable operation of the treatment equipment is difficult to guarantee.

The gas purified by the first-stage washing tower 2 enters a second-stage washing tower 3, the clean water is adopted to wash and purify the oil smoke waste gas and cool the gas again, and the second-stage washing tower 3 can be one of a rotational flow plate tower and a packed tower.
The gas washed and purified by the second-stage washing tower 3 is dehydrated and demisted on the top of the tower and then sent to the filter 4, fine particles in the purified gas are further filtered, the gas is further dehydrated and demisted, two stages of filtering units are arranged in the filter 4, the filtering precision is gradually improved, the filtering grade is G4-F8, the filtering materials are all stainless steel, and each stage of filtering material is provided with an automatic cleaning spray head.
The gas after the filtration of filter 4 gets into electrostatic oil smoke clarifier 5, and electrostatic oil smoke clarifier 5 is high, low pressure two-stage process electric field formula structure, and the first section is the ionization region, adopts high-voltage electric field ionization, makes dust, granule electrified, and the second section is the dust collecting zone, adopts low-voltage electric field to collect electrified dust, granule, to oil smoke exhaust purification deep purification. Each stage of electric field is provided with an automatic cleaning device.
The gas deeply purified by the electrostatic oil fume purifier 5 enters an adsorber 6, VOCs in the gas are adsorbed and deodorized by adopting activated carbon, so that the gas is thoroughly purified, and the purified gas is sent to a chimney 10 by a fan 9 to be discharged.
The filter 4 and the electrostatic oil fume purifier 5 are both provided with automatic cleaning devices, and the cleaning devices can be started periodically to automatically clean the filtering materials and the electrode plates. During the washing, need stop fan 9 earlier, from 60 ~ 80 ℃ hot water that hot-water tank 8 stored, send to filter 4 and electrostatic oil smoke clarifier 5 in through 7 pressure boost of scavenging pump in, wash filtering material and plate electrode, resume its purification efficiency and reduce the cost of manual maintenance.
A pH value probe 14 is arranged in the first circulating water tank 15, when the pH value of the washing liquid in the first circulating water tank 15 is reduced to a set value, the dosing pump 13 is automatically started, liquid caustic soda is extracted from the medicine storage tank 12 and sent into the first circulating water tank 15 to be supplemented with the liquid caustic soda, and when the pH value of the washing liquid in the first circulating water tank 15 reaches the set value, the dosing pump 13 is automatically stopped, so that the washing liquid is kept to operate within a set pH value range.
The above examples and other figures merely represent one embodiment of the present invention, and are intended to illustrate and not to limit the invention. It will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
