Description
Technical field
This technology is related to a kind of steam raising plant of sterilising soil by steam machine, and specifically, it is one kind with combustion of pulsing
The steam raising plant that electromotor produces steam as origin of heat is burnt, after steam raising plant produces steam, by steam disc
Steam is passed through into soil, disinfecting soil is sterilized.
Background technology
China's facilities horticulture industry is quickly grown in recent years, and is progressively developed to scale, intensive direction, technical merit
Have increased significantly.According to statistics, China's facilities horticulture obtains nearly 20% plantation with the planting industry soil less than 3%
The industry output value, and this data increasing year by year.
Facilities horticulture belongs to annual plantation, is chronically at the environment of high temperature, high humidity, makes some pathogenic bacteria worms in facility plastic greenhouse
Ovum and insect are bred year after year, accumulate in a large number, and intractability is larger in cultivation matrix or soil.In addition facilities horticulture
Crop cultivation speciality degree is higher, and the crop species of plantation are relatively fewer, so continuous cropping is prevailing, cause worm's ovum in soil, funguses and
The accumulation year after year of virus, some soil-borne disease insect pests take place frequently, and seriously constrain the development of facility cultivation, general underproduction when disease occurs
20%～40%, underproduction when serious is even had no harvest up to more than 60%.Therefore, it is to change to the disinfecting soil in facilities horticulture
Crop ecological environment in kind garden, improves agriculture value, promotes the Important Action of agro based economic development.
Facilities horticulture soil disinfection method is broadly divided into two big class of chemical disinfection and physical disinfection.Chemical disinfection is due to pollution
Problem, development are restricted, and physical disinfection method is due to environmentally friendly, pollution-free, it has also become the production of facilities horticulture clean and effective is excellent
The soil disinfection method for first considering, with preferable development prospect.Physical disinfection mainly have vapor sterilization, soil hot water process,
The methods such as solar disinfection, microwave sterilization.Wherein vapor sterilization compared with other physical disinfection modes, with development is early, technology
Basic good, low cost, sterilization be uniform, thoroughly, it is especially good to deep soil Disinfection Effect the characteristics of, progressively replace other physics
Disinfection way becomes the main way of facilities horticulture soil disinfection, and has obtained developing faster.Existing soil disappears both at home and abroad
Malicious equipment popular feature is that volume is big, energy consumption is big, is not suitable for carrying out operation in middle-size and small-size facilities horticulture at home.Therefore, it is badly in need of
Develop that a small volume, energy consumption be little, flexible, efficient facilities horticulture soil disinfection machine.
The steam raising plant that sterilising soil by steam machine is used at present mostly is stable state combustion type, stable state type steam raising plant
There are the shortcomings such as efficiency of combustion is low, equipment is complicated, fuel consumption is more, expensive, harmful gas emission is big.
The content of the invention
The purpose of this technology is to provide a kind of high combustion efficiency, and harmful gas emission is few, simple structure, lightweight, body
The steam raising plant of the little sterilising soil by steam machine of product.
The steam raising plant of the sterilising soil by steam machine, including there are the cylinder of water, pulsating combusting device in inside；Steam goes out
Mouth is located at cylinder top；Pulsating combusting device includes combustor, spark plug, petrol tank, carburetor, tail pipe, aerofluxuss decoupling chamber；Burning
It is connected with tail pipe between room and aerofluxuss decoupling chamber；Combustor, tail pipe, aerofluxuss decoupling chamber are respectively positioned in cylinder；Pulsating combusting device
Work, as fuel in burning Indoor Combustion, the high-temperature flue gas of generation are discharged to cylinder by tail pipe and aerofluxuss decoupling chamber to gasoline
Outward, heat passes to the water in cylinder by the wall of combustor, tail pipe and aerofluxuss decoupling chamber.
Pulsating combusting device produces steam, pulsating combusting device small volume, hot-cast socket effect to the water heating in cylinder as thermal source
Rate is high, using on sterilising soil by steam machine, in the case where equal steam condition is produced, can reduce gasoline consumption, mitigate whole machine
Weight, diminution machine volume.Pulsating combusting device mainly includes combustor, spark plug, petrol tank, carburetor, tail pipe；Combustor with
Tail pipe is communicated, and carburetor includes inlet plenum, the trunnion for communicating, and is provided with and can unidirectionally enter into air inlet room on the locular wall of inlet plenum

Referring to the sterilising soil by steam machine described in Fig. 9 steam raising plant 1 include inside have water vertical cylinder 1-2,
The pulsating combusting device vertically placed.Steam (vapor) outlet 1-13 is located at cylinder top.Referring to Figure 10, pulsating combusting device includes corrugated combustion
Burn room 1-7, spark plug 1-14, petrol tank（It is not shown）, carburetor 1-8, tail pipe 1-5, aerofluxuss decoupling chamber 1-1.Aerofluxuss decoupling chamber
Inwall arrange radiating fin.
Combustor, tail pipe, aerofluxuss decoupling chamber are respectively positioned in cylinder.Carburetor and petrol tank are arranged outside cylinder.
Cylinder bottom arranges inlet opening 1-6 and discharge outlet 1-15.Liquidometer 1-3 and Floating Ball Liquid Level are set outside cylinder by the top
Control device 1-4.Can be basically unchanged with designated water level, the liquid level in holding cylinder body by floating ball liquid level control device.If cylinder
Water level is too low in vivo, and floating ball liquid level control device will open inlet opening allows water to enter；, whereas if water level is too high in cylinder,
Floating ball liquid level control device may turn off inlet opening.
Using pulsating combusting device as thermal source, cold water is pumped into from bottom water inlet by automatic water inlet system, by ball float liquid
Level control device designated water level, and maintain water level constant, can be from external observation water level by liquidometer 1-3.Pulsating combusting device
Use Helmholtz type pulsating combusting devices；Using gasoline as main fuel, the high-temperature flue gas for producing that burn pass through tail pipe
Discharge with aerofluxuss decoupling chamber, heat passes to the cold water in cylinder by combustor, tail pipe and aerofluxuss decoupling chamber tube wall.When cold
Water produces steam when being heated to boiling, steam is exported by steam (vapor) outlet.
Beyond the water surface in cylinder, the heat discharged by the combustor that this part is surfaced can be by cylinder for the upper end of combustor
The saturation vapourss of body upper end are converted to saturation dry saturated steam by post bake.
Corrugated combustor, can increase heat exchange area, burning is more fully carried out；Stretch with certain
Property, the thermal expansion stress of combustor is can compensate for, beneficial to the carrying out that intermittent combustion is stable.
Cylinder top can also arrange relief valve, thermometer, pressure gauge etc..When inner barrel pressure exceedes design pressure
When, excess steam is discharged by relief valve, to ensure the safety of steam raising plant.
Work is finished, and can discharge the remaining water of inner barrel by discharge outlet.
