Abstract
The utility model discloses a steam recovery device that can be applied in sunlight greenhouses. The utility model operates when a ventilator, above-ground pipelines, underground pipelines, and a water collecting device are arranged in vinyl houses or greenhouses. The utility model has the function of steam recovery.
Description
Technical field:
The utility model relates to a kind of steam retracting device, particularly relates to a kind of steam retracting device that is applicable to closed agricultural facilities such as greenhouse by solar heat, plastic tunnel.
Background technology:
Industrialized agriculture also claims protection ground agricultural, is meant activities in production such as (greenhouse, booth etc.) carry out in facility crop, vegetables, flowers, fruit.It is the important component part of modernization agricultural.Because agricultural facilities such as greenhouse by solar heat plastics booth structurally have closure, make its inside be limited in the confined space because of the steam that soil evaporation and plant transpiration are produced, this will make, and air humidity increases in the greenhouse, and it is long-time, keep too high air humidity constantly, not only can produce injury, also bring out various crop pests easily plant.Therefore, the greenhouse air humidity method of controlling of taking both at home and abroad at present is a forced ventilation, makes steam be discharged into the outside, greenhouse.
The agricultural production of carrying out in greenhouse and plastic tunnel links together with irrigation, worsening shortages along with the water globe resource, although how improving the water utilization rate of industrialized agriculture will become the problem that attracts people's attention sprinkling irrigation will be arranged at present, the irrigation technique that drip irrigation etc. are advanced, but it just stresses aspect " throttling ", and the steam that is collected in the greenhouse also is a kind of form of water resource, the way that it is discharged into the outside, greenhouse in the past, be actually a kind of waste to water resource, if it can be recycled, will further improve water utilization rate from the side of " increasing income ".Because this part steam contains any pollutant component hardly through the rising generation of soil evaporation and crop, so also be unusual precious water resource.
From the Transformation Principle of water as can be known, the solid-state liquid state of water, conversion between the gaseous state will be attended by the absorption and the dispose procedure of energy, is a kind of energy dispose procedure from gaseous state to the condensation process that liquid state changes, as long as can the energy that contain in the steam be discharged by a kind of mechanism, vaporous water just can change aqueous water into from the agrometeorology principle as can be known, the result of " greenhouse effect " is that the temperature that the temperature in the greenhouse will be higher than outside the greenhouse is many, and show obvious diurnal variation feature more, but the soil temperature in the greenhouse, temperature in the following ground of the 20cm degree of depth particularly, and unlike temperature, change acutely, do fluctuation slowly in the small range but maintain basically.This just makes between temperature in the greenhouse and the ground temperature and bigger temperature difference occurred, if the steam of building up in the greenhouse is got off with being incorporated into, the energy that hot and humid air had will discharge there, and meanwhile steam can condense gradually becomes aqueous water.
Technology contents:
The utility model purpose is to provide a kind of steam recovery system that improves greenhouse or booth irrigation water availability; The purpose of this utility model also is to provide a kind of greenhouse or booth that improves the irrigation water availability.
The purpose of this utility model realizes by setting up water-saving system: lay the plurality of rows pipeline in the greenhouse side by side, pipeline divides the ground air to suck part and underground ground-gas heat exchange section; One end of pipeline elevates above the soil, and at the floor outlet place of pipeline exhaust fan is installed; The pipeline under ground portion is installed inclined; The underground exit of pipeline connects and is arranged on underground moisture recovery section dust-collecting bucket or water cellar, tank.
The utility model energy supply part can adopt three kinds of forms, i.e. solar cell, wind-driven generator rural power or civil power.Because system's power consumption only is on exhaust fan and draft fan, and its required electric power seldom, so the energy of these three kinds of forms can both satisfy system's running needs.
The ground air of the utility model system sucks being provided with of part and highly is not less than 1m, also can be the greenhouse height 1/3～1/2 between, can adopt height mode straggly to arrange, the power bracket of exhaust fan is at 1.4m
3/ s-2.2m
3/ s.
Underground ground-gas the heat exchange section of the utility model system is made up of some pipelines of burying underground side by side, distance between each pipeline is not less than 30cm, the pipeline of ground-gas heat exchange section can be regulated according to the length in greenhouse in underground arrangement length, generally being good about 15～20m, pipeline is underground inclined, its depth-averaged of burying underground is not less than 40cm, to guarantee not influence the growth of crop root in the greenhouse.
The utility model pipeline can adopt the PVC goods of inner wall smooth, pipeline is a double-decker, diameter of inner pipe is 160cm～200cm, outer tube diameter is 200cm～240cm, can inject frozen water or filling dry ice between the inner and outer pipe, inside at interior pipe is equipped with the half garden shape damping screen that Open Side Down every some distances, and damping screen is a polyethylene products, and width of mesh is 2mm * 2mm.
The moisture recovery section of the utility model system is the fluid-tight underground water cellar of wall, tank or bucket, its be provided with the degree of depth will with the ground-gas heat exchange of system that the degree of depth is set is suitable, its volume size is not less than 1m
3
The aeration portion of the utility model system will be arranged on the opposite side in the greenhouse opposite with air suction part, it is provided with the height that height can suck the part exhaust fan a little more than air, the flabellum diameter of draft fan is 40～60cm, and the wind speed in draft fan exit is 4～6m/s.
By day, solar radiation makes in the greenhouse and heats rapidly, crop and soil evaporation are strong, and steam fills the air gathering in the greenhouse, at this moment start-up system, the acting in conjunction of exhaust fan and draft fan is inhaled in the pipeline steam or the humid air in the greenhouse, be imported into undergroundly along pipeline, because subsurface temperature is low, hot and humid air produces exchange heat here, steam condenses on the inwall of pipeline in loses heat, and the formed globule will flow in the dust-collecting bucket along the pipeline that tilts.
When in the pipeline damping screen being arranged, gas is subjected to the effect of damping screen to reduce flow velocity in pipeline, be beneficial to carry out between steam and the pipeline heat exchange, the frozen water or the dry ice that inject between the recovery channel inner and outer pipe can promote the steam cooling, on inner tubal wall, produce and condense, condensate water flows into tank along pipeline, and the moisture of recovery can be used for chamber crop production once more.
System's operation does not produce any influence to the hothouse production activity, can plant various crops, vegetables or flowers by the production schedule in the greenhouse, and the required moisture of crop is by irrigating supply.Evapotranspire and the steam that produced of soil evaporation by crop in the greenhouse, be inhaled into ground-gas heat exchange section when moving, condense and to be utilized once more after converging in system.The utility model mainly relies on natural energy resources-solar radiation, the energy consumption of system is very little, and the moisture of recovery does not pollute, and can be directly used in agricultural production or drinks, the rate of recovery can reach 30%～40% of duty, and the crop production in the greenhouse is had no adverse effects.
