Energy-saving and temperature-control type hot-blast stove

Abstract

The invention relates to an energy-saving and temperature-control type hot-blast stove. The hot-blast stove comprises a shell and an inner container, wherein a combustion chamber and an ash unloading chamber are arranged at the lower part the inner container. The hot-blast stove is characterized in that a broken line-shaped flue is arranged at the upper part of the inner container; a flue gas outlet is formed in the tail end of the broken line-shaped flue, and a plurality of radiators are arranged on the outer wall of the broken line-shaped flue; an air inlet is formed in the lower part of the shell, a centrifugal blower is connected to the outer side of the air inlet, a branched pipeline is connected to the side wall of the air inlet, and the other end of the branched pipeline penetrates through the shell and is inserted into the ash unloading chamber; and an electromagnetic valve or a manual gate valve controlled by an indoor temperature sensor is arranged on the branched pipeline, and a hot air outlet is formed in the top of the shell. The energy-saving and temperature-control type hot-blast stove is high in heat exchange efficiency and convenient to use, and the problems of high heat exchange efficiency and energy consumption of existing agricultural hot-blast stoves are solved.

Description

technical field [0001] The invention relates to an energy-saving and temperature-controlling hot air stove, which is mainly used for indoor heating in winter in greenhouses and poultry farms. Background technique [0002] At present, the hot blast stoves used in greenhouses and poultry farms are mainly composed of shells, inner tanks, blowers and induced draft fans, etc., which have the following problems: 1. The inner tank is cylindrical. In order to increase the heat exchange area, the inner tank is usually The height of the tank is high, and the blower is required to blow the air into the shell, and the heat-carrying air is drawn out by the induced draft fan, which consumes a lot of power, but there is still the problem of low heat exchange efficiency; 2. When the indoor temperature is lower than the set temperature 3. There is also a structural design in which round pipes are interspersed in the inner tank as an air passage. Although the heated area is increased to a cer...

[0002] At present, the hot blast stoves used in greenhouses and poultry farms are mainly composed of shells, inner tanks, blowers and induced draft fans, etc., which have the following problems: 1. The inner tank is cylindrical. In order to increase the heat exchange area, the inner tank is usually The height of the tank is high, and the blower is required to blow the air into the shell, and the heat-carrying air is drawn out by the induced draft fan, which consumes a lot of power, but there is still the problem of low heat exchange efficiency; 2. When the indoor temperature is lower than the set temperature 3. There is also a structural design in which round pipes are interspersed in the inner tank as an air passage. Although the heated area is increased to a certain extent, due to structural limitations, the narrow space in the air passage causes heat congestion , low heat transfer efficiency
