Abstract

The utility model relates to a garden water-and-air heating furnace which as a modern agricultural technique equipment is used for heating, raising temperature, constructing an artificial climate and defending frostbite for greenhouses, big sheds and big scale industrial and efficient agricultural producing of the north district of China. The utility model is characterized in that the furnace consists of a boiler, an assistant machine, a hot air duct and an underground hot water pipe; the boiler is a normal atmosphere boiler, and a hot water outlet is arranged under an hot air outlet of the boiler and is connected with a circulation pump and then is connected with a feeding-distributing water cylinder which is connected with one end of the underground hot water pipe; the other end of the underground hot water pipe is connected with a returning-distributing water cylinder. The utility model combines boiler heat-supplying, hot air heating and low temperature hot-water ground radiation heating together to realize two heat exchanging modes by one furnace simultaneously. And the temperature of the hot air outlet is 150 180 DEG C to 180 DEG C for a greenhouse space heating. For the low temperature hot water, the temperature of the hot water outlet is 30 180 DEG C to 50 DEG C for raising temperature of the root soil level of greenhouse plants.

Description

Gardening heating heats the hot water thermal wind furnace

Technical field

The utility model relates to and a kind ofly is applicable to that the northern area of China winter produces greenhouse, booth and large factory high-efficiency agriculture and carries out heating and heat, build artificial climate, pre-frost damage prevention take place modernized agricultural technology equipment---gardening heating heats the hot water thermal wind furnace.

Background technology

At present, domestic north of china in winter cold climate reached more than half a year, and average minimum temperature is at-15～-25 ℃.Often occur " cold winter " weather of the cloudy snow of low temperature in recent years, the regional minimum temperature that has reaches below-30 ℃.Because strong cold shut tide invasion and attack or continuous the moon snow microthermal climate, crops such as the vegetables in greenhouse, flowers, melon and fruit, forest just suffer freeze injury easily.Heliogreenhouse is resisted low temperature and is frozen that cold to wait the ability of diastrous weather be limited, though daylight accumulation of heat, but nocturnal temperature descends, the temperature of the interior space generally can only maintain about 2～5 ℃ to the time after midnight, when cold wave is invaded, himself unable resisting, the indoor crop root grown layer soil moisture is then lower, and this " two low " phenomenon is very harmful to crop growthing development.Because greenhouse structure is unreasonable, daylighting, heat-insulating property do not reach requirement, have in greenhouse, booth, adopt traditional wall with flues, stove and the heating of ordinary hot homogeneous solution-type reactor, heat supply, intensification, temperature does not still reach requirement, soil temperature raising be can not solve at all, crop growth and market supply influenced.

Summary of the invention

The utility model is at above-mentioned north of china in winter greenhouse, polyhouse-based agriculture production, owing to exist heating facility to fall behind, and cause the chamber crop freeze injury, influence agricultural production and market supply, and provide a kind of greenhouse, booth and large factory high-efficiency agriculture are carried out heating, heated, can build artificial climate, pre-frost damage prevention takes place, and increases economic efficiency---and gardening heating heats the hot water thermal wind furnace.

The heating of the utility model gardening heats hot water thermal wind furnace content Description:

The heating of the utility model gardening heats the hot water thermal wind furnace, it is characterized in that: be made up of boiler, subsidiary engine, hot air duct and geothermal water pipeline four parts; Boiler is a normal-pressure boiler, and the top that chimney, boiler are set at the top of boiler is provided with hot-blast outlet connection hot air duct, the cold wind import connects an air blast; Be hot water outlet below hot-blast outlet, be connected with a water circulating pump that divide water vat to be connected with water inlet again, water inlet divides water vat to be connected with an end of underground hot pipeline, the other end of underground hot pipeline divides water vat to be connected with backwater; One blowoff valve is set in the bottom of boiler divides water vat to be connected with a water temperature, flow control valve with backwater, the bottom of boiler also is provided with one and adds water tank; Being cinder chamber below boiler grate, is the combustion chamber above, and the outside of combustion chamber is a water jacket, and the top of combustion chamber is vaporizer, and the top is the hot blast Heat Room;

The heating of the utility model gardening heats the hot water thermal wind furnace, adopt boiler heat supplying, hot-air heating, low-temperature water heating ground radiation heating to combine, realize that a stove and accessory produces two kinds of heat exchanges, i.e. high-temperature hot-airs simultaneously, the hot-blast outlet temperature is 150～180 ℃, for greenhouse space heating; Low-temperature water heating, hot water outlet temperature are 30～50 ℃, heat for chamber crop root soil layer.Because hot blast, hot water constantly flow, heat radiation, have quickened the thermal cycle of the interior space and underground layer, even, moist, the not roasting seedling of temperature.For best artificial climate is built in winter greenhouse production, prevention and avoid freeze injury to take place, can satisfy that various crop is grown seedlings winter, when cuttage, cultivation to room temperature, the needs of gentle water temperature, promote plant growth effectively, shorten the growth cycle of crop, improve output and quality.The flue gas of boiler emission is nontoxic, tasteless, pollution-free, and oxygen content reaches more than 30% in the air.The utility model can be widely used in various greenhouses, booth heating, heat and crop such as vegetables of large factory high-efficiency agriculture, special vegetable, flowers, melon and fruit, forest return grow seedlings season, cultivation, cuttage etc., large-area soil and soilless culture nutrient fluid are heated; Large-scale livestock farm, circle, chamber; Edible fungus culturing, the production of hybrid seeds; In the space of large-scale aquaculture industry, the water, underground heat exchange and the heating of large-scale public place, the conveyance system that heats.
