Abstract
The utility model discloses an exhaust heat boiler in a cement kiln, and has a boiler body. The utility model is characterized in that the boiler body has a U-shaped arrangement, and an inlet gas duct and an outlet gas duct are both arranged at the upper part, and connected with the boiler body. The utility model has the advantages that the structure is reliable, the heating surface abrasion is less, the metal consumption is less, and the gas duct arrangement is simple.
Description
Technical field:
The utility model relates to boiler technology, is a kind of waste heat boiler, specifically, is a kind of kiln heat recovery boiler.
Background technology:
Kiln heat recovery boiler has vertical and horizontal two kinds of arrangement forms at present, and the vertical boiler flue gas flows from top to bottom, and the horizontal boiler flue gas flows from front to back, and exhaust gases passes is a uiform section.The high temperature section flue gas flow rate is big; The low-temperature zone flue gas flow rate is little, and both differ greatly, the heating surface pipe serious wear.This kind Boiler Metallic consumption is big, imports and exports the flue complicated layout.
Summary of the invention:
The purpose of this utility model provide a kind of rational in infrastructure, heating surface wear is little, metal consumption is few, flue is arranged simple kiln heat recovery boiler.
The utility model technical solution is: a kind of kiln heat recovery boiler, body of heater is arranged, and it is characterized in that: body of heater is that U-shaped is arranged, imports and exports flue all on top, and is connected with body of heater.
The body of heater that U-shaped described in the utility model is arranged has two vertical sections, and the bottom of two vertical sections is connected by connecting flue.One in two vertical sections is the high temperature section that is connected with cement kiln, and another is the low-temperature zone that is connected with high temperature section.The top of high temperature section is provided with the air inlet flue; The top of low-temperature zone is provided with the flue of giving vent to anger.Bottom in high temperature section is provided with ash hole.
The beneficial effects of the utility model are: rational in infrastructure, heating surface wear is little since the flow direction flue gas flow rate evenly, compact conformation, the Boiler Metallic consumption also has by a relatively large margin and descends.Import and export flue and all be connected with boiler,, arrange simple with the original flue of cement kiln orientation basically identical on top.
Below in conjunction with drawings and Examples the utility model is further described:
Description of drawings:
Accompanying drawing is the structural representation of a kind of kiln heat recovery boiler of the present utility model.
The specific embodiment:
Accompanying drawing has been described an embodiment of the present utility model, in this embodiment, body of heater 1,2 is arranged, and body of heater 1,2 is that U-shaped arranges, import and export flue 3,4 is all on top, and is connected with body of heater 1,2 respectively.The body of heater 1,2 that described U-shaped is arranged has two vertical sections, and the bottom of two vertical sections 1,2 is connected by connecting flue 5.One in two vertical sections 1,2 is the high temperature section 1 that is connected with cement kiln, and another is the low-temperature zone 2 that is connected with high temperature section 1.The top of high temperature section 1 is provided with air inlet flue 3; The top of low-temperature zone 2 is provided with the flue 4 of giving vent to anger.Be provided with ash hole 6 in the bottom of high temperature section 1.
Boiler in the utility model becomes U-shaped to arrange, goes out on flue gas is enterprising, and the high temperature section flue gas is toward current downflow; The low-temperature zone flue gas up flows, and the bottom connects with being communicated with flue.The flow direction exhaust gases passes is a unequal section, and the high temperature section exhaust gases passes is big; The low-temperature zone exhaust gases passes is little.The high temperature section flue gas flow rate is than smaller; The low-temperature zone flue gas flow rate is than big, and both are more close, are more or less the same.Most cigarette ashes obtain sedimentation in the bottom is communicated with flue.High temperature section descends to some extent because of flue gas flow rate, and the wearing and tearing of heating surface pipe also have minimizing; Though the low-temperature zone flue gas flow rate increases, because of the flue gas after the sedimentation contains very a spot of cigarette ash, the wearing and tearing of heating surface pipe significantly reduce.
Claims (5)
