Abstract
The invention relates to an air heater. The air heater comprises a jacketed chimney, a pre-heating chamber, a three-return heat exchanging box, a fine water column humidifier, a fan and a combustion chamber. The chimney is on the top of the air heater. A central pipe of the chimney is communicated with the three-return heat exchanging box. A jacket of the chimney is connected with the pre-heating chamber. A pre-heating air outlet is arranged at the lower part of the pre-heating chamber. The inlet of the fan is connected with a pre-heated air outlet. The outlet of the fan is connected with a pre-heated air inlet. The fine water column humidifier is arranged in a pre-heated air inlet pipe. Some water mist is sprayed in the pre-heated air inlet pipe. The air heater disclosed by the invention has the benefits of high heat efficiency, low cost and convenient installation and use. CO2 concentration and humidity in a greenhouse are ensured.
Description
Technical field
The present invention relates to a kind of air-heater.
Background technology
Air-heater is mainly used in the heating of agricultural greenhouse (or hot house).Present agriculture hot house heating has following several method: the one, at booth one end a coal stove is set, and the damp and hot of flue gas is dissipated in the booth by earthenware, this method thermal efficiency is low, and thermic load is difficult to improve; Another kind method is to place radiator (being radiator) in booth, the hot-water boiler of Natural Circulation or forced circulation is set outside booth, this method cost height, be difficult to the air quality that guarantees that plant growth is required, air seldom upgrades, and the CO2 that is absorbed by photosynthesis can't in time replenish, for this reason, have to improve by the method for " leaking informaton " (promptly with the hot-air in the outdoor cold air displacement canopy) the regularly concentration of CO2, " leaking informaton " must cause a large amount of losses of heat in the booth.
Summary of the invention
The deficiency of aspects such as the purpose of this invention is to provide a kind of air-heater, thermal efficiency height, cost are low, easy to install, guarantee CO2 concentration and humidity in the greenhouse, overcome to have down to be difficult to the air quality that guarantees that plant growth is required in the technology, and the thermal efficiency is low.
The objective of the invention is to be achieved through the following technical solutions:
A kind of air-heater, comprise chuck chimney, preheating chamber, three backhaul heat exchange box, thin water column humidifier, blower fan and combustion chamber, chimney is positioned at the top of air-heater, its central tube communicates with three backhaul heat exchange box, and its chuck links to each other with preheating chamber, is provided with pre-hot blast outlet in the bottom of preheating chamber, the inlet of blower fan links to each other with the outlet of pre-hot blast, the outlet of blower fan links to each other with the import of pre-hot blast, in the inlet tube of pre-hot blast thin water column humidifier is set, and sprays into a certain amount of water smoke at this.
Beneficial effect of the present invention is: thermal efficiency height, cost are low, easy to install, guarantee CO2 concentration and humidity in the greenhouse.
Description of drawings
With reference to the accompanying drawings the present invention is described in further detail below.
Fig. 1 is the structural representation of the described air-heater of the embodiment of the invention;
Fig. 2 is the cutaway view of Fig. 1.
Among the figure:
1, the chimney of strap clamp cover; 2, preheating chamber; 3, three backhaul heat exchange box; 4, the outlet of pre-hot blast; 5, combustion-supporting gas ventilating opening; 6, the import of pre-hot blast; 7, humidifier; 8, hot-blast outlet; 9, blower fan; 10, combustion chamber.
The specific embodiment
Shown in Fig. 1-2, the described a kind of air-heater of the embodiment of the invention, the chimney 1 that comprises the strap clamp cover, preheating chamber 2, humidifier 7, combustion chamber 10 and blower fan 9, the chimney 1 of described strap clamp cover is positioned at the top of air-heater, the central tube of the chimney 1 of strap clamp cover communicates with three backhaul heat exchange box 3, chuck in the chimney 1 of strap clamp cover links to each other with preheating chamber 2, be provided with the outlet 6 of pre-hot blast in the bottom of preheating chamber 2, the inlet of blower fan 9 links to each other with the outlet of pre-hot blast 4, the outlet of blower fan 9 links to each other with the import of pre-hot blast 6, in the pipe of the import 6 of hot blast in advance thin water column humidifier 7 is set, and sprays into a certain amount of water smoke at this, make air humidification, be beneficial to the growth of plant.Preheated air behind the humidification is used for combustion-supporting by the air that the ventilating opening that is arranged on 10 bottoms, combustion chamber adds after the fraction preheating, the high-temperature flue gas that coal or oil firing generate in combustion chamber 10 links to each other with the central tube of the chimney 1 of strap clamp cover by the standpipe of three backhaul heat exchange box 3, be divided into three backhauls outside the pipe, most of air after the preheating is blown into warmhouse booth by two hot-blast outlets 8 after being heated to rated temperature, and described combustion chamber 10 can be coal furnace or oil burner.
