Abstract
The utility model relates to a nursery pond circulating heat supply system which comprises a hot water boiler (1), a main water supply pipe (2), a main return water pipe (3), a circulating pump and multiple parallel nursery ponds (4). A water outlet (5) of the hot water boiler is parallelly connected onto a heat exchanging coiler water supply port (6) in each nursery pond through branches of the main water supply pipe (2), a heat exchanging coiler water outlet (7) in each nursery pond (4) is collected to the main return water pipe (3) through a collecting branch pipe, the main return water pipe (3) returns again to be connected with a return water port (8) of the hot water boiler, and the main water supply pipe (2) is provided with a section of same travel pipe (9) equivalent to the length from a first branch point to a last branch point. The nursery pond circulating heat supply system can realize heating uniformity during large-area heating and temperature stability of the nursery ponds and creates a growing environment suitable for thriving of tobacco floating nursery seedlings.
Description
Technical field
The utility model relates to specialized cigarette kind seedling nursing device; Be specifically related to a kind of nursery pond circulating heat supply system.
Background technology
The floating seedlings work of tobacco all is the February that is performed until next year December since the first year every year, nearly 3 months nursery stage, and this period, substantially between 0 to 15 ℃, the extreme temperature that often has about-5 ℃ occurred in the general temperature in south.And the preference temperature of tobacco seedling growth is 22 ℃-28 ℃, but under natural environment or in the general booth, the key elements such as the temp. and humidity that need in the tobacco seedling growth process this period and illuminance are uncontrollable.Therefore, the cigarette seedling can not normally be emerged and grow, and high stem strong seedling cultivation rate is low, can not bring out strong sprout for transplanting at normal nursery stage, often cause seedling age long, the cigarette seedling is thin and weak, the transplanting time pusher, be transplanted to the land for growing field crops after the cigarette seedling be difficult to early growth and quick tiller, affect quality and the style characteristic of tobacco leaf.
The growing environment that prior art will provide a kind of suitable cigarette seedling to grow up strong and sturdy needs in the tobacco seedling system.Mainly be to increase the boiler hot-water heating system; The boiler hot-water heating system of prior art adopts the hot-water boiler circulation heating, that is: hot-water boiler → hot water → diversion box → pump pressurization squeeze in the circulating line → circulation cooling → heating nursery pond → hot water circuit after the backheat homogeneous solution-type reactor.Finish thus the closed circuit process of a heating, heat radiation; This result is owing to the modularization distribution design of nursery pond, and diversion box pipeline length out has short, and the restriction of insulation cost causes the nursery pond of nearly diversion box end and the thermal losses of far-end nursery pond inconsistent, and the difficult temperature Centralized that realizes is evenly controlled.
The utility model content
In order to overcome defects, technical problem to be solved in the utility model is: a kind of nursery pond circulating heat supply system is provided.Realize homogeneous heating in the large tracts of land heating process; Build the grow up strong and sturdy growing environment of needs of a kind of suitable tobacco floating seed rearing seedling.
The technical solution of the utility model is: a kind of nursery pond circulating heat supply system comprises hot-water boiler, main-supply, main water return tube, circulating pump and a plurality of nursery pond arranged side by side; The delivery port of hot-water boiler is connected on the heat exchange coil feed water inlet in each nursery pond side by side by main-supply branch, heat exchange coil delivery port in each nursery pond is collected to main water return tube through compiling arm, and main water return tube returns the water return outlet that connects hot-water boiler again; It is characterized in that: one section same journey pipe that is equivalent to from first branch point to length between last branch point is arranged on the above-mentioned main-supply, so that first branch point of main-supply from the tube side of hot-water boiler delivery port farthest, and first branch point is nearest from the tube side of hot-water boiler water return outlet behind heat exchange coil; Last branch point of main-supply is nearest from the tube side of hot-water boiler delivery port, and last branch point behind heat exchange coil from the tube side of hot-water boiler water return outlet farthest.
Compared with the prior art, the utility model has the advantages that: arrange with the journey pipe at main-supply, so that the distance of the heat exchange coil in from hot-water boiler hot water out to each nursery pond equates, thereby each nursery pond thermal losses that has guaranteed different distances is consistent, the convenient temperature Centralized that realizes is evenly controlled, and then realizing homogeneous heating in the large tracts of land heating process, the control of passing ratio valve finally reaches the nursery pond temperature stabilization at 35 ℃; Build the grow up strong and sturdy growing environment of needs of a kind of suitable tobacco floating seed rearing seedling.
