Description
The present invention relates to a smoke and deodorizer incorporating a hood with a flame inflow prevention function, and more particularly, to a smoke removal deodorization device that includes a flame inflow prevention plate, an electromagnetic flame inflow blocking plate, a space partition to be extinguished by an interlock control circuit, Ionization, electro-organic, oxidation, and oxidation by applying the very high electric field energy generated by the high-voltage generator to the polluted air containing the softener and the oil, The present invention relates to a ventilation and deodorizer incorporating a hood having a flame inflow blocking function capable of simultaneously removing a hydrophilic liquid material hydrophilic odor material by decomposing a covalent bond of a contaminant by a reaction such as reduction.
The local ventilation is caused by harmful substances such as fabric softener, fish odor, edible oil, oil, dust, etc. generated in the sources such as the tenter process of the textile dyeing industry, the manufacturing process of industry, It is a ventilation method that improves the harmful indoor environment by collecting and removing by using mechanical force before.
Local ventilation facilities are generally installed in the order of Hood, Duct, Air Purifier, Fan (FAN), Exhaust Duct, Exhaust Port, but the small ventilation facilities of the food industry are installed in the order of omitted air purifier facilities. do.
The most important part of the local ventilation facilities is a hood and an air purification facility, and the hood is a suction part for collecting and sucking harmful substances emitted from a generation source into one place and introducing it into a local ventilation facility. Therefore, it is essential to design the hood appropriately so that local ventilation facilities can effectively control hazardous materials with minimal ventilation and minimal power consumption.
If the hood is erroneously designed, the oversized size increases device design cost and power consumption, or insufficient size results in unsatisfactory control of the hazardous material. Early improperly designed hoods are often impossible to calibrate after device design and construction.
The industrial hood has established the hood design standards and guideline (AGGIH, KOSHA) under the Air Quality Preservation Act and Industrial Safety and Health Act, and pointed out design errors in the trial environment at the trial environment and industrial safety corporation But there is no specialized design guideline for the food industry, and there is no design examination institution, and it is mainly designed by the kitchen appliance manufacturer's own design and duct construction company by the experience of individual who have unclear design standard, Effective control (exhaust) is difficult.
The hood is divided into Up Wards (U) hoods for collecting the upward airflow in the high-temperature source accompanied by a strong upward airflow in accordance with the suction direction, Downward (U) hoods for collecting large- D) The hood is divided into a receiving (R) hood and a lateral (L) hood that collect dust that emits in a certain direction as in a rotating machine.
The Receiving Hood (R) is a hood in which the harmful substances are attracted and discharged in a direction along with the air stream in a direction, which is a hood for forging, melting, dyeing, Upstream canopy type hoods, which are one type of recipe hood, are mainly used in high temperature emission sources such as cooking devices in foodservice industries.
When using a reciprocating hood (R), it is necessary to minimize the amount of sucked air by installing it as close as possible to the source in consideration of the scattering direction in order to collect the harmful substances sufficiently and to reduce the suction of surplus air. The upper canopy type installed in the kitchen of the catering industry has various sizes of cooking utensils and various differences in the height of the cooker. Especially, In the case of the hood, it is impossible to place the cooking hood close to the source and to cook the flip over the food through the process of raising the frying pan to a certain height after rapidly raising the food. Considering the duct speed, duct material selection, static pressure loss, duct selection, It is necessary to take into consideration the calculation of the exhaust volume, the loss of dynamic pressure on the hood and the duct, the selection of the blower considering the voltage loss, and the selection of the shape of the ventilation hole. The local ventilation design error Since the required amount of exhaust is not ensured, the harmful substances leak and diffuse into the room, and the central portion of the hood connected to the duct is relatively more sucked at the suction side than the side edge, In order to ensure a better exhaust performance, it is often the case that a filter installed to collect dust and oil in the hood is used and frequently used, and a duct design error causes an appropriate conveying speed Is not ensured and dust that enters into the hood and stomach during the cooking process The oil is mixed and accumulated in the duct without being discharged to the outside, which increases the risk of potential fire. To reduce the cooking time, the oil such as olive oil and cooking oil used for cooking is further heated to a high temperature to the vicinity of the ignition point The evaporation amount of the oil is increased due to the use of heating, and the vapor of the high temperature is expanded by the bulky density, so that it is cooled and dipped in the process of suction transfer to a long distance in the duct, and the high temperature environment is maintained throughout the cooking process Therefore, the inside of the dust mixed with the oil deposited inside is stored and the oil is evaporated, thereby creating a dangerous environment in which the possibility of fire is very high.
In recent years, there have been frequent cases where olive oil, soybean oil, corn oil, peanut oil, cooking oil, etc. are heated to above the boiling point during the cooking process, and the ignited flames are introduced into the duct by the suction force generated by the blower, The internal energy accumulation by the combustion heat generated during the combustion process increases the evaporation amount of the oil to increase the scale of the fire, which makes it difficult to suppress the fire, and increases the human and material losses. More than 150 cases of this kind of fire are collected annually.
Also, among the nonionic surfactants such as polyoxylethylene alkyl ether, polyoxy fatty acid ester and polyoxyethylene alkylphenol ester among the softening agents discharged from the process at a high temperature of about 220 to 250 ° C in the tenter process, In the cleaning method, which is a cleaning method which is currently used mainly for the mixed polluted gas, hot noxious gas is introduced into the cleaning device, and the cleaned water comes into contact with the cleaning water sprayed from the nozzle, and some is recovered into the cleaning water storage tank, The other part is mixed with the water vapor that is mixed with the vaporized water and discharged to the atmosphere through the exhaust port of the washing tower. The water vapor is absorbed into the atmosphere and disappears, but the oil mist is not absorbed into the atmosphere, It is stagnant, giving visual displeasure, and complaints are constantly being raised.
In order to solve this problem, since the washing water is overflowed during the operation period and the oil mist which is suspended is discharged, the amount of water is consumed by the amount of overflow, and the secondary problem of generating the waste water is caused .

This technique is complicated and the cleaning liquid is continuously consumed. When the injection nozzle is clogged, the cleaning liquid is not sprayed in the form of atomization. Therefore, It is sprayed in a bar shape and flows into a countertop, so cooking of food is difficult, and there is no function of preventing flame inflow, emergency shutdown, digestion function and purification of harmful substances.
Korean Patent Publication No. 10-1172708 (wet gas scrubber) is a two-stage scrubber that treats basic gas and acid gas at the same time. As the scrubbing liquid spraying method, a spray pipe and a perforated plate are used instead of an injection nozzle, And the pressure loss was reduced by using no filler. The demistered gas-liquid separator was replaced with porous structure and orifice structure, but cleansing water does not have flame inflow prevention, emergency shutdown and extinguishing function.
Korean Patent Publication No. 10-0945038 (plasma reactor and plasma scrubber using the same) supplies a fuel, a carrier gas, and an ozone gas to a plasma generated in a plasma reactor, processes the polluted gas by combustion and oxidation reaction, This method removes the white oil containing the oil mist, but it is complicated, the problem of supplying separate fuel and carrier gas, the problem of preventing flame inflow and emergency, There is no function.
Korean Patent Publication No. 10-1155562 (U-shaped high-pressure scrubber) is a two-stage scrubber that is installed inside a cylindrical scrubber reactor by spraying cleaning water to a syngas flowing into a high temperature to remove gas treatment and fine dust It is possible to delay the pollution rate of the washing water by minimizing the amount of dust in the waste water by separately collecting the collected dust on the stove and separately collecting it in the separate dust storage tank. However, it is advantageous to prevent flame inflow, emergency shutdown, It is not possible to remove white smoke containing oil mist.
Korean Patent Publication No. 10-1492379 (Tenta Exhaust Gas Treatment System) burns process exhaust gas emitted from a tenter process in a separately installed combustion furnace to reduce the amount of generated vapor and raw materials, and installs an air heat exchanger in the exhaust gas The method of recovering the waste heat in the combustion gas and heating the heating medium can remove the oil mist, but the initial investment is high and the energy consumption is high.
That is, the hood designing and manufacturing technology of the local ventilation system for the food and beverage cooker developed up to now has a weak part in the prevention of the inflow of fire during cooking, the prevention of the flame propagation, the digestion and the purification of harmful substances, The scrubber for treating the exhaust gas containing the fabric softener component (lipophilic fluid, Oil Mist) discharged from the process has a problem in terms of efficiency of removal of contaminants due to cleaning water contamination, It has less development of flame inflow prevention, quick flame propagation prevention function and fire extinguishing function and development of hood designing and manufacturing technology with low maintenance cost, ensuring better efficiency of removal of harmful substances including white smoke, safety and durability The development of air purifying technology that can be done is not yet known.

The polluted air containing the harmful substances flowing into the
The
The selected hood can be equipped with a side baffle or an air curtain to prevent the spread of harmful substances and to minimize the effect of turbulence and attach a flange at the foot end of the hood, The flow rate can be minimized.
Further, at least one of a flange, a baffle, a taper, a splitter vane, and a slot may be selected so that the velocity distribution of the air containing the pollutant introduced from the hood opening is uniform. If the inflow air of the check pipe exceeds 60 degrees, the inflow air flow is separated from the inclined surface and the airflow distribution becomes poor. Therefore, the inclination angle of the inflow ramp is in the range of 30 to 60 degrees, When it is not present, it spreads at an angle of 16 degrees to 20 degrees.
In order to prevent hazardous substances generated during the process (cooking, etc.) at the source from being sucked into the hood and scattered in the room to prevent occupants from being exposed to harmful substances, the airflow control speed Vs of the hood ) Is as shown in Equation (1), and the capture velocity (Vc) should be larger than the scattering velocity (Vg).
The suction speed of the hood (Vs = Vc - Vg) ----------------- Equation 1
- The rules for safety and health standards in Korea Industrial Safety and Health Law and the recommended speed of control speed (Vc) for industrial ventilation design are
* Control speed (Vc) of the circulation in the quiet atmosphere with almost no speed (gas generated from the stew, liquid level). Voltage device: 0.25 m / s to 0.5 m / s
* The control speed when the harmful substance is scattered at a low speed in a relatively quiet air current is 0.5 m / s to 1.0 m / s
* Control speed of shaking (frying, stir-frying) actively in a place with quick start Vc = 1.0m / s ~ 2.5m / s
* Control speed of Vc = 2.5m / s ~ 10m / s in case of splashing at very high speed in workshop with very fast start (tenant of dyeing factory)
An appropriate control speed is selected from among the numerical values of the control speed Vc = 0.5 m / s to 5 m / s at the hood tip adopted in the present invention.
When the exhaust amount in the hood opening is increased, the capacity of the air purifier of the local ventilation system is increased, the duct diameter of the duct is enlarged, and the capacity of the blower is increased. In addition to the contaminated air volume, indoor air is also sucked and discharged. Therefore, indoor airflow unevenness and energy loss are large. When the suction flow rate is low, harmful air is not sucked into the hood, As it can cause health problems, the appropriate amount of exhaust in the hood is calculated as follows.

In addition, upflow caused by heat buoyancy from a high temperature source such as a gas stove in the upper portion of the textile industry and a cooking stove in the kitchen of the restaurant industry, and a collecting discharge of soot, dust, It is effective to use it as a recipient.
In this case, it is not preferable to simply calculate the ventilation area by multiplying the opening area of the hood by the control speed (Vc) because the harmful substances are passively captured by the thermostatic lifting force rather than collecting harmful substances by the suction airflow of the hood.
As described above, in the case of a reciprocating hood, a flow rate notation is used as a method for obtaining the necessary air blowing amount without introducing the control speed. In order to calculate the airflow using this flow rate method, the structural characteristics of the heat source and hood, heat rising air flow, induction air flow, and turbulence should be considered.
FIG. 4 is a cross-sectional view illustrating structural characteristics and airflow characteristics applied when designing a hood of a hood of a ventilation and deodorizer incorporating a hood with a flame inflow prevention function according to the present invention. Referring to FIG. 4A, the structural characteristics of the heat source will be described. In a state in which the heat source is upwardly moved upward by the convection in the heat source and the induction air stream is sucked from the surroundings, the heat source is slightly spread just above the heat source, It spreads and rises.
When there is no turbulence in the surroundings, it spreads at an angle of 16 to 20 degrees, but there is always a little turbulence in the room. Therefore, when considering the effect of the recipe canopy hood, The angles of the extension lines of the combustion device are set to be 40 degrees in the diagonal direction at both side edges of the canopy hood.
The size of the heat source is determined by selecting the diameter when the circle is circular, the length of one side when it is a forward direction, and the short side when it is a rectangle. When the symbol is E and the height of the hood is H, ) Is F3, it is expressed as follows.
F < 3 > = E + 0.8H [
And the height H is preferably set at a position just below the heat source as possible so as to satisfy the condition of H? 0.7, thereby effectively discharging the contaminants at a minimum displacement.
Also, the heat rising air flow amount is calculated by the air pollution diffusion model embodiment, which is the amount of the harmful air current which is discharged from the source of the high heat source such as the cooking table, the combustion device, and the upper portion of the food industry.
Q1 =
Q = heat rising air flow rate (m3 / min)
r = Equipment on the side of the heat source (round and forward 1)
Circle when it looks like a circle / Short / long when it is a rectangle / Scene
A = heat source area
: Temperature difference between the heat source and ambient air (℃) 3.8
tm = temperature of heat source (캜)
Z = virtual altitude of the hood (m) 3.9
In addition, the " leak limit flow rate " is a phenomenon in which the hot air flows upward from the source of the hot source such as the combustion device of the countertop, The airflow is called an induction airflow.
Since the heat rising air and the induction air flow have a large temperature difference, the induction air flow is increased compared with the case where there is no temperature difference due to local vortex generation. As shown in Fig. 4-2 of the attached figure 4, it becomes larger than the heat rising air flow Q3. That is, since Q 3 <Q 1 + Q 2, the amount corresponding to (Q 1 + Q 2) - Q 3 is leaked into the room without being sucked into the hood.
As shown in Figure 3-216, when the amount leaking into the room is absorbed by mechanical force, all of the ascending airflow and induction airflow are sucked into the hood. In this case,
Q3 = Q1 + Q2
= Q1 + (1 + KL) - " (10) "
Here, KL =
= Induction flow rate / Heat rising air flow rate
= Q2 / Q1
Calculate using
The minimum blowing amount of
Q3 = Q1 / 1+ (mK L ) ---------------------- Equation 11
= Q < 1 > (1 + K D )
The size of the turbulence and the safety factor of leakage are as follows.
