Embodiment 1

[0037] Such as figure 1 , figure 2 , image 3As shown, the present invention includes a steam stove main body 1, a combustion chamber 2 is arranged in the steam stove main body 1, and a burner 3 is installed in the combustion chamber 2; it is characterized in that, the steam stove main body 1 is also provided with a steam chamber 4 and a The steam chamber 4 is provided with a steam outlet, the smoke outlet of the combustion chamber 2 is connected with a heat conduction mechanism 5, the heat conduction mechanism 5 passes through the steam chamber 4, and after the heat conduction mechanism 5 passes through the steam chamber 4, press several The waste heat exchange cavities pass through several waste heat exchange cavities sequentially; the last waste heat exchange cavity along the flow direction of the waste gas in the heat conduction mechanism 5 is connected with a tap water inlet pipe; the main body 1 of the steam stove is also equipped with a replenishing water tank 11 , T...

Embodiment 2

[0043] On the basis of Embodiment 1, two waste heat exchange cavities are arranged in the main body 1 of the steam stove. The cavity 7 is connected; the heat conduction mechanism 5 includes a high-temperature exhaust gas heat-conducting pipe 51, a medium-temperature exhaust gas heat-conducting pipe 52, and a low-temperature exhaust gas heat-conducting pipe 53 connected in sequence. In the waste heat exchange chamber 6 , the low-temperature waste gas heat conduction pipe 53 is arranged in the low-temperature waste heat exchange chamber 7 ; the tap water inlet pipe is connected to the low-temperature waste heat exchange chamber 7 .

[0044] The high-temperature exhaust gas exchanges heat with the steam chamber 4 through the high-temperature exhaust gas heat pipe 51, and the high-temperature exhaust gas at 500°C to 600°C becomes medium-temperature exhaust gas at 140°C or higher. The medium-temperature exhaust gas exchanges heat with the medium-temperature waste heat exchange cham...

Embodiment 3

[0046] On the basis of Embodiment 1 or Embodiment 2, the wall thickness of the high-temperature exhaust gas heat-conducting pipe 51 , the wall thickness of the medium-temperature exhaust gas heat-conducting pipe 52 , and the wall thickness of the low-temperature exhaust gas heat-conducting pipe 53 are successively reduced.

[0047] The wall thickness of the high-temperature exhaust gas heat-conducting pipe 51, the wall thickness of the medium-temperature exhaust gas heat-conducting pipe 52, and the wall thickness of the low-temperature exhaust gas heat-conducting pipe 53 are successively reduced, so that each section of the heat-conducting tube can adapt to the temperature of the exhaust gas inside, ensuring that each section of the heat-conducting tube has Suitable heat resistance. In the case of ensuring that the heat-conducting tube has sufficient heat resistance, the heat-conducting tubes are set to have different wall thicknesses, so that the wall thickness of the heat-con...

Abstract

The invention relates to the field of steam ovens, in particular to a waste heat recovery and energy conservation integrated steam oven. The steam oven comprises a steam oven body. A combustion chamber is formed in the steam oven body. A burner is mounted in the combustion chamber. The steam oven body is further internally provided with a steam chamber and a plurality of waste heat exchange cavities communicating in sequence. The steam chamber is provided with a steam outlet. A smoke outlet of the combustion chamber communicates with a heat guide mechanism. The heat guide mechanism penetratesthrough the steam chamber and then penetrates through the waste heat exchange cavities in sequence according to the communicating sequence of the waste heat exchange cavities. A tap water inlet pipe is connected to the final waste heat exchange cavity in the flowing direction of waste gas in the heat guide mechanism. A make-up water tank is also mounted on the steam oven body. A float ball valve is arranged on the make-up water tank. The other end of the float ball valve communicates with the steam chamber through a pipeline. The waste heat recovery and energy conservation integrated steam oven provided by the invention can recover waste gas heat in a sectional mode and improve the utilization rate of waste gas heat.

Description

technical field [0001] The invention relates to the field of steam stoves, in particular to an integrated steam stove with waste heat recovery and energy saving. Background technique [0002] Steam has a wide range of uses in the fields of national production and life, such as steaming rice, steamed buns, cooking, sauna, disinfection, beauty, etc., and in production such as chemical heating, washing and dyeing, pharmaceuticals, building material production, food production, etc. [0003] The utility model patent with the patent application number CN92241374.6 discloses a steam cooker, the heating device of which is composed of a fuel injection burner, a heat exchange channel and a draft flue. The water tank, because the heat exchange channel twists and turns inside the water container. The water tank has a water inlet check valve controlled by the water level and a water outlet check valve controlled by the water pressure difference. It can keep the water container to main...
