Abstract
A method for using HF high-voltage discharge to generate ozone for killing the tobacco bettle and tobacco snout moth in tobacco warehouse features that the air is compressed, the molecular sieve drier is used to lower the dew point of air, HF high-voltage discharge is used to generate ozone, and the ozone is blowed via pipeline into tobacco warehouse.
Description
Technical field
The present invention relates to kill in a kind of tobacco warehouse the method for tobacco storage insect, particularly a kind of high-frequency and high-voltage discharge generation ozone that utilizes is killed in the tobacco warehouse method of storage pest such as lasioderma serricorne and tobacco snout moth in the tobacco warehouse.
Background technology
In the tobacco storage process, cause domestic tobacco material to lose nearly 1,000,000,000 yuan in the damage by disease and insect and the every year of going mouldy.The main method of control tobacco storage damage by disease and insect is to utilize phosphine and other agricultural chemicals to fumigate processing both at home and abroad at present.Its weak point is tobacco in process of growth, uses agricultural chemicals to kill damage by disease and insect, and residue of pesticide are arranged in the product, uses agricultural insecticide that tobacco is polluted once more at storage, and the while is contaminated environment also, influences operator ' s health, and the consumer is constituted harm.Phosphine fumigation exists fire to fall into and suffers from, the annual incident that all has phosphine fumigation to cause fire disaster takes place, agricultural chemicals is limited to the killing effect of insect and worm's ovum, insect is easy to generate drug resistance, can not continuous effective kill adult, easily form new insect pest,, can't control in good time insect pest because phosphine fumigation is handled general every year and only carried out twice.
Summary of the invention
Purpose of the present invention is exactly that a kind of method of utilizing high-frequency and high-voltage discharge generation ozone to kill storage pest such as lasioderma serricorne and tobacco snout moth in the tobacco warehouse will be provided; utilize ozone that the damage by disease and insect of tobacco warehouse is prevented and treated; thoroughly changed the environmental pollution that agricultural insecticide caused in the past; help protecting the consumer health, can reduce labor strength.Particularly because the strong oxidizing property of ozone itself and self decomposition do not produce the characteristics of harmful substance, meet the environmental protection trend requirement of international popular, help thoroughly killing continuously the tobacco storage damage by disease and insect, reduce the tobacco leaf loss that the tobacco leaf damage by disease and insect causes, save production cost, improve the tobacco enterprise economic benefit.
The object of the present invention is achieved like this: it is to utilize air as raw material, by compressor to air pressurized to 0.7Mpa, through three-stage filtration, oil content in the air is reduced to 0.001ppm, dust size is reduced to 0.01 μ, utilize the molecular sieve adsorption dryer to reduce the raw air dew point to-30 ℃～-50 ℃, by high-frequency and high-voltage discharge generation ozone gas, utilize pipeline, devices such as blower fan are evenly distributed to the storage space with ozone, the air circulation number of times is 5 times～10 times/hour in the warehouse, according to different desinsection requirements, and control ozone concentration 10ppm～200ppm, in 10 hours～300 hours processing time, kill storage pests such as lasioderma serricorne and tobacco snout moth.The warehouse room temperature is-10 ℃～40 ℃, and air humidity is 30%～95% in the warehouse.Ozone generator exit concentration 〉=12mg/L.
The principle of ozone desinsection is: ozone has reinforcement, oxidized protein, and damage insect human body film destroys respiratory circulatory system, makes insect death.
Adopt technique scheme, the present invention has following characteristics:
1, environmental protection and economy because raw material is an air, can reduce pesticide dosage, and ozone can spontaneously decompose, and environment is not had contamination hazard;
2, safety non-toxic, because concentration is in the ppm level, the sunken trouble that does not have phosphine fumigation to cause fire is avoided the secondary pollution to the storage article simultaneously, the protection consumer health;
3, easy and simple to handle, adopt the situation that automated control technology can take place according to insect pest at any time to carry out the desinsection operation, alleviate the storage labor intensity;
4, improve the quality of products, ozone can the part degrading tobacco in residual harmful components such as agricultural chemicals, chemical fertilizer and bio-hormone, shorten the alcoholized tobacco time, reduce harmful substance contents such as nicotine, Jiao.
Description of drawings
The invention will be further described below in conjunction with embodiment.
Embodiment
The present invention utilizes high-frequency and high-voltage discharge generation ozone, utilizes the stifling storage of ozone tobacco, reaches the method for killing and control the tobacco storage damage by disease and insect.Supercharging is evenly distributed to warehouse space to high-concentrated ozone gas through blower fan, enters in the pest body by insect breathing and metabolism, destroys the insect respiratory circulatory system, reaches the purpose that eliminates destructive insects.
A kind of method of utilizing high-frequency and high-voltage discharge generation ozone to kill storage pest such as lasioderma serricorne and tobacco snout moth in the tobacco warehouse, it is to utilize air as raw material, by compressor to air pressurized to 0.7Mpa, through three-stage filtration, oil content in the air is reduced to 0.001ppm, dust size is reduced to 0.01 μ, utilize the molecular sieve adsorption dryer to reduce air dew point, by high-frequency and high-voltage discharge generation ozone gas, utilize pipeline, blower fan is evenly distributed to the storage space with ozone, the air circulation number of times is 5 times～10 times/hour in the warehouse, control ozone concentration and stifling processing time, kills storage pests such as lasioderma serricorne and tobacco snout moth.Ozone concentration is 10ppm～200ppm in the warehouse, and the stifling processing time is 10 hours～300 hours.Air dew point is handled to-30 ℃～-50 ℃, and the warehouse room temperature is-10 ℃～40 ℃, and air humidity is 30%～95% in the warehouse.Ozone generator exit concentration 〉=12mg/L.
Studies have shown that by experiment, when ozone concentration is lower than 10ppm, the stifling growth to insect pupa, ovum of ozone suppresses DeGrain, form new insect pest easily, the ozone of 10ppm is stifling to have certain killing effect to adult and larva though be lower than simultaneously, need the long period but fumigate, easily cause certain influence producing; When ozone concentration is higher than 200ppm, though good to the insect killing effect, because half life period of ozone is short, keep that concentration needs the supplemental ozone amount big in the warehouse, cause equipment investment big, the operating cost height, economic benefit is bad.The stifling processing time was controlled at 10～300 hours, the low concentration ozone fumigation time is longer relatively, and fundamental sum present stage agricultural chemicals fumigation time unanimity can not impact production process, high-concentrated ozone is stifling to need the time short, is fit to the process of preventing and treating to explosive insect pest.The requirement of environmental temperature-10 ℃～40 ℃, indoor air humidity 30%～95%, domestic southern and northern natural humidity is satisfied substantially, when environmental temperature and humidity low more, the ozone generator operating efficiency is high more, and environmental temperature and humidity are high more, because the metabolic activity of insect enhancing is good more to the insect killing effect.For stablizing of high-concentrated ozone in the maintenance warehouse, to ozone generator exit concentration requirement 〉=12mg/L.
