Description
Technical field
This utility model belongs to a kind of nutritional solution microwave sterilization machine.
Background technology
Compare with soil cultivation, the Soilless Culture Methods take nutrient fluid cultivation as main body can be produced the green non-pollution food of high yield and high quality more, and the technical way that wherein relies on is that nutritional solution precisely detects regulator control system.Present nutrient fluid cultivation has open and closed two kinds.The waste liquid of open discharge is contaminated surface water and groundwater, makes river, lake water cause severe contamination, thereby affects underground water source.All adopt at present enclosed sterilization method to seal sterilization to nutritional solution, closed nutrient fluid cultivation is mainly to carry out in the greenhouse of high temperature, high humidity and booth, be the impact of avoiding the nutritional solution waste liquid that surrounding enviroment are caused, must carry out nutritional solution sterilization and recycling, to stop the injury of growing and crop being caused of various pathogen, existing nutritional solution sterilization method has following several:
Heat treatment mode: different with lethal time (as Celsius in tobacco mosaic virus (TMV) 90 ℃-10 seconds of pathogen lethal temperature different in the nutritional solution waste liquid; And reaping hook belong to fungus and tobacco mosaic virus (TMV) kill needs Celsius 85 ℃-3 minutes).When sterilizing with heat treatment method, if adopt the sufficiently high temperature, sufficiently long time can thorough disinfection, but energy consumption be high, and the nutritional solution waste liquid amount is large, and mobility is large, adopts this mode will increase substantially disinfection cost.At present, normally at first analyze before sterilization and have several pathogen and main pathogen in nutritional solution, then take to carry out disinfection for the temperature and time sterilization parameter of the main pathogenic fungi.But this kind method equipment investment cost is higher, and during operation, energy consumption is larger, if sterilization is not thorough, some heat-resisting pathogen can survive.
The sand filtration mode: advantage is the chemical composition that does not change mill water culture nutrient solution, can filter the fungus of phytophthora, pythium, and investment and operating cost are minimum.Shortcoming is that Fusarium spp., virus, nematicide can only remove 90%～99.9%, and the filter tank will account for the larger area in the greenhouse in addition, and cost of investment is high.
The ultraviolet mode: different microorganisms is different to ultraviolet tolerance.Killing bacteria and fungus need 100mJ/cm
2, killing virus needs 250mJ/cm
2In addition, contain various granules in nutritional solution, these granules can block ultraviolet, and the virus that is hidden in the particle back is difficult to be killed.Usually filter before sterilization.But investment and operating cost are higher, are difficult to promote the use of.
The oxidant mode: ozone is typical disinfection way, and its bactericidal effect is relevant with time and concentration that nutritional solution exposes in oxidant.Need to filter in advance the minimizing content of organics and improve germicidal efficiency.But when a large amount of nutritional solutions need to be processed, process will be carried out in batches, needs pretreatment and safeguard procedures, and processing cost is high, wastes time and energy.
Summary of the invention
The purpose of this utility model is a kind of nutritional solution microwave sterilization machine of design, can effectively carry out disinfection to the antibacterial in the nutritional solution waste liquid, have simple in structure, environment friendly and pollution-free, good sterilization effect, the low and advantage easy to use of use cost.For this reason, this utility model mainly is comprised of original fluid container, disinfection tank and regeneration flow container, in shelter-clad, sealing is provided with disinfection tank, the tank body in the disinfection tank outside is provided with microwave generator, the entrance point of disinfection tank communicates with the original fluid container lower end by catheter and pump, and the port of export of disinfection tank communicates with regeneration flow container upper end by another catheter and effusion meter.Described original fluid container upper end is provided with the stock solution entrance.Described regeneration flow container lower end is provided with leakage fluid dram.The said structure design has realized the purpose of this utility model.
The utility model has the advantages that and can effectively carry out disinfection to the antibacterial in the nutritional solution waste liquid, have simple in structure, environment friendly and pollution-free, good sterilization effect, the low and advantage easy to use of use cost can be promoted the use of.
Description of drawings
Figure is structural representation of the present utility model.
The specific embodiment
As shown in the figure, a kind of nutritional solution microwave sterilization machine mainly is comprised of original fluid container 2, disinfection tank 4 and regeneration flow container 9.The interior sealing of shelter-clad 6 is provided with disinfection tank, the tank body in the disinfection tank outside is provided with microwave generator 5, the entrance point of disinfection tank communicates with the original fluid container lower end by catheter and pump 3, and the port of export of disinfection tank communicates with regeneration flow container upper end by another catheter 8 and effusion meter 7.Described original fluid container upper end is provided with stock solution entrance 1, and the stock solution entrance communicates with the tank body that stores the nutritional solution waste liquid.Described regeneration flow container lower end is provided with leakage fluid dram 10, and leakage fluid dram communicates with the tank body of the recycling nutritional solution of store regenerated.Effusion meter can demonstrate liquid measure.
The electric wave that microwave generator sends belongs to Non-ionizing radiation, is that a kind of wavelength is 0.001mm～1m, and frequency is the electromagnetic wave of 300～300000MHz.When biology is in the microwave electromagnetic field field, cell is impacted and is shaken, cellulosa is destructurized, the cell permeability is strengthened, destroyed the inside and outside material balance of cell, cause microwave energy quick penetration object and directly make object intramolecule frictional heat, causing antibacterial dead, reaching the purpose of sterilization.This utility model mainly utilizes microwave on the impact on electronics around the microbial cell film and ion concentration of the heat effect of water isopolarity molecule and microwave electromagnetic field, change the membrane passage energy, affect the pathogen eubolism and cause its dead biological effect.
During use, used nutritional solution waste liquid flows in original fluid container from the stock solution entrance, the pumped entrance point that goes out to pass through afterwards disinfection tank flows in disinfection tank, microwave generator on disinfection tank carries out disinfection, sterilizes the nutritional solution waste liquid that flows through, flow in the regeneration flow container through effusion meter and another drain pipe through the port of export of the nutritional solution after sterilization by disinfection tank, then enter into production link through liquid outlet.Whole disinfection ring all carries out under sealed environment, and is pollution-free, uses safety, a small amount of staff namely to operate whole disinfecting process.
In a word, this utility model can effectively carry out disinfection to the antibacterial in the nutritional solution waste liquid, have simple in structure, environment friendly and pollution-free, good sterilization effect, the low and advantage easy to use of use cost.
