Description
Technical field
The utility model belongs to boiler industry, specifically, relates in particular to a kind of new type low temperature heat pipe waste heat boiler.
Background technology
For a long time, traditional water pipe waste heat boiler is the water pipe heating surface what adopt aspect the low-temperature flue gas waste heat recycling mostly, because flue-gas temperature is low, exhaust gas volumn is large, for reaching designing requirement, what heating surface was arranged usually is more, floor space is larger, wasted the space of boiler room, for preventing cold end corrosion, exhaust gas temperature is generally all still very high simultaneously, considerable heat still is wasted, and the necessary shutdown maintenance replacing after damaged tubular of traditional water pipe waste heat boiler, cause the pause of whole production line, always bring very large economic loss.
The utility model content
Water pipe waste heat boiler floor space traditional in the prior art is large in order to solve, the maintenance difficulty, and the utilization rate of waste heat of flue gas is not high, the defective that causes considerable heat to be wasted, and the utility model provides a kind of new type low temperature heat pipe waste heat boiler.
The utility model is achieved through the following technical solutions:
A kind of new type low temperature heat pipe waste heat boiler, comprise burner hearth, burner hearth is provided with inlet flue duct and exhaust pass, is provided with steam-generating bank heating surface, economizer in the burner hearth, the burner hearth top is provided with drum, and drum was connected with economizer with the steam-generating bank heating surface respectively by communicating pipe.
Described steam-generating bank heating surface comprises header first, header second, heat pipe and header, the header first is connected pipe with header second and is connected, the header first was communicated with header by communicating pipe, heat pipe is with one section flue that places in the burner hearth of fin, and the other end of heat pipe passes header second and enters in the pipe.
Roof of the furnace is provided with ceiling, and burner hearth is provided with the platform staircase outward.
Compared with prior art, the beneficial effects of the utility model are:
The steam-generating bank heating surface adopts the heat pipe with fin to carry out heat exchange, compare traditional water pipe waste heat boiler, has advantages such as not affecting the utility model operation after high, the single heat pipe of heat transfer coefficient damages, and thoroughly solved the pipe leakage problem, alleviate dew point corrosion, avoided steam-generating bank fouling of heating surface, stifled grey phenomenon;
The steam-generating bank heating surface can assemble in advance, makes several modules, is convenient to during use install, so that the utility model compact conformation, floor space is little, is convenient to long-term safety stable operation.

Fig. 2 is the partial enlarged drawing of A part among Fig. 1.
In the drawings, 1, ceiling; 2, platform staircase; 3, drum; 4, steam-generating bank heating surface; 5, inlet flue duct; 6, exhaust pass; 7, economizer; 8, header first; 9, pipe; 10, header second; 11, heat pipe; 12, header; 13, fin.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
A kind of new type low temperature heat pipe waste heat boiler comprises burner hearth, and roof of the furnace is provided with ceiling 1, and burner hearth is provided with platform staircase 2 outward; Burner hearth is provided with inlet flue duct 5 and exhaust pass 6, is provided with steam-generating bank heating surface 4, economizer 7 in the burner hearth, and burner hearth top is provided with drum 3, and drum 3 is connected with economizer with steam-generating bank heating surface 4 respectively by communicating pipe and is connected; Described steam-generating bank heating surface 4 comprises header first 8, header second 10, heat pipe 11 and header 12, header first 8 is connected with header second by pipe 9 connections, header first 8 was communicated with header 12 by communicating pipe, heat pipe 11 is with one section flue that places in the burner hearth of fin 13, and the other end of heat pipe 11 passes header second 10 and enters in the pipe 9.
The utility model is taked single drum vertical mode in use, is used in conjunction with coke oven.Connect each pipeline, inlet flue duct 5 is connected with the exhanst gas outlet of coke oven, exhaust pass 7 is connected with air-introduced machine, during work, low-temperature flue gas enters in the burner hearth by inlet flue duct 5, carry out heat exchange with steam-generating bank heating surface 4 and economizer 7 successively, at last by behind the exhaust pass 7, utilize air-introduced machine to discharge; In this process, heat pipe 11 in the steam-generating bank heating surface 4 is with the heat in the end absorption flue of fin 13, and heat carried out heat exchange by the other end of heat pipe 11 and the water in header second 10 and the pipe 9, the steam that produces imports in the header first 8, by header 12 steam in each header first 8 is compiled again, then by communicating pipe steam is delivered in the drum 3; Low-temperature flue gas further carries out heat exchange with economizer 7, comes heated feed water, improves feed temperature, and feedwater enters drum 3 by feed pipe, for the user.
