Planting and cultivation shed split type heat preservation furnace

Abstract

The invention discloses a planting and cultivation shed split type heat preservation furnace, which comprises a fuel box, an air blower, a fuel conveying device, an air inducing pipe, a combustion furnace and a heat conduction pipe, wherein the combustion furnace is arranged in a shed; the fuel box and the air blower are arranged outside the shed; the fuel box supplies fuel to the combustion furnace through the fuel conveying device; the air blower blows air to the combustion furnace through the air inducing pipe; and one end of the heat conduction pipe is connected with a hot air outlet of the combustion furnace, and the other end of the heat conduction pipe extends out of the shed. First of all, heat on the wall body of the combustion furnace is dispersed and retained in the shed; then after the heat conduction pipe is in contact with air in the shed, a large amount of heat is dispersed in the shed through heat conduction, so that the heat conversion efficiency is greatly improved; moreover, the heat conduction pipe is in direct contact with the air to perform heat conversion, so that the pressure of the air in the shed is lower than that of air which is directly poured or blown; and therefore, air leakage in the shed is relatively small, heat loss is low, and aims of synergism, energy conservation, safety and environment friendliness are fulfilled.

Description

technical field [0001] The invention relates to a heat preservation furnace for planting and cultivating greenhouses. Background technique [0002] The insulation of planting and aquaculture greenhouses generally uses a combustion furnace to provide energy. The fuel tank supplies fuel to the combustion furnace through a fuel delivery device, and a heat conduction pipe and an exhaust gas pipe are installed above the combustion furnace. Both the fuel tank and the combustion furnace are placed outside the greenhouse, and the hot gas generated in the combustion furnace is treated by the waste gas treatment device and then connected to the greenhouse with a fan or heat pipe. In this way, the heat in the furnace wall of the combustion furnace and a large amount of heat in the exhaust gas are discharged outside the greenhouse, causing heat loss and waste. Moreover, due to the hot air poured or blown in from the outside, the air pressure in the greenhouse rises higher, causing the a...

Problems solved by technology

In this way, the heat in the furnace wall of the combustion furnace and a large amount of heat in the exhaust gas are discharged outside the greenhouse, causing heat loss and waste. Moreover, due to the hot air poured or blown in from the outside, the air pressure in the greenhouse rises higher, causing the air to stay longer. Short, large leakage, and third, install an extra fan, wasting electricity
