Embodiment
For make above-mentioned purpose of the present utility model, feature and advantage, can be more obvious understandable, below in conjunction with the accompanying drawings and tool
Body embodiment is described in further detail to the utility model.
As shown in Figure 1 and Figure 2, in a specific embodiment, horizontal waste incineration waste heat recovery pot of the present utility model
Stove, including body of heater 1, the middle at the top of body of heater 1 are provided with drum 2 in the horizontal direction, and drum 2 is provided with water inlet 8 and saturation
Steam (vapor) outlet 9.The bottom of the side wall of body of heater 1 is provided with gas approach (not shown), and the top of the side wall of body of heater 1 is provided with exhanst gas outlet
(not shown).
The gas approach is connected by pipeline with outside garbage combustion device, the high temperature cigarette that garbage combustion device is produced
Gas enters the interior intracavitary of body of heater by gas approach, and the flue gas after heat exchange is arranged by exhanst gas outlet from the inner chamber of body of heater
Go out.
The water inlet 8 set on the drum 2 is connected by pipeline with outside water tank, and outside water pump is by water tank
Interior water is pumped directly into the drum 2.Saturated vapor outlet 9 and the outside steam set on the drum 2 is converted
Device (such as steam-driven generator) is connected, and the saturated vapor in drum 2 eventually enters into steam reformer with reality by steam (vapor) outlet 9
The recycling of waste heat in existing flue gas of refuse burning.
The left and right sides of the bottom of body of heater 1 is arranged with the first header 3 and the second header 4.
The drum 2 is connected with first header 3 by the first convection bank 5 to be returned with forming the first convective heat exchange
Road, first convection bank 5 runs through the inner chamber of the body of heater 1.Specifically, first convection bank 5 includes some the
Water in one sinking convection tube and some first rising convection tubes, the drum 2 enters by the first sinking convection tube
In first header 3, the water vapour in first header 3 rises convection tube through described first and entered in the drum 2.
The drum 3 is connected with second header 4 by the second convection bank 6 to be returned with forming the second convective heat exchange
Road, second convection bank 6 runs through the inner chamber of the body of heater 1.Specifically, second convection bank 6 includes some the
Water in two sinking convection tubes and some second rising convection tubes, the drum 2 enters by the second sinking convection tube
In second header 4, the water vapour in second header 4 rises convection tube through described second and entered in the drum 2.
Below, by taking the first convective heat exchange loop as an example, the convective heat exchange being discussed in detail in the utility model is former
Reason：
Water in drum 2 through the first sinking convection tube flow downwardly into first header 3, flow process with body of heater
High-temperature flue gas air-flow in 1 carries out heat exchange and is heated evaporation；Steam water interface in first header 3 is through described first
Tedge, which is flowed upwardly into, to carry out heat exchange with the high-temperature flue gas air-flow in body of heater 1 again in the drum 2, flow process and is entered
One step heating evaporation；Steam water interface enters after the drum 2, is separated into water by the water separator in drum and saturation is steamed
Vapour, saturated vapor therein is imported into the steam reformer (such as steam-driven generator) of outside.
Convective heat exchange principle and the convection current in the first convective heat exchange loop due to the second convective heat exchange loop
Heat exchange principle is identical, and here is omitted.
It can be seen that, horizontal waste incineration heat recovery boiler of the present utility model by setting in the both sides of boiler 1 respectively
One header 3 and the second header 4, drum 2, the first header 3 and the second header 4 are laid out in " A " font, and its one side improves this reality
