Description
Technical field
The utility model relates to high enthalpy steam heat collection servicing unit, especially boiler high-enthalpy steam superheating device in steam boiler.
Background technology
In prior art, tradition steam boiler is not installed superheater, saturated vapor under production nominal operation pressure, under 0.8Mpa operating pressure, the condensate water that saturated vapor contains 3%d, the thermal efficiency is in 60% left and right, and the saturated-steam temperature of new boiler device fabrication can only reach 170 ℃, the old boiler working condition of scaliness declines, vapor (steam) temperature constantly declines, and thermal loss progressively increases, therefore, the measure that can select comprises that increase operating pressure, to maintain steam enthalpy, makes the corresponding raising of equipment energy consumption and potential safety hazard.
Utility model content
The purpose of this utility model is to provide a kind of boiler high-enthalpy steam superheating device, with heat-collecting box structure, improves steam boiler vapor (steam) temperature.
The purpose of this utility model will realize by following technical measures: upper collecting chamber and lower header are settled up and down, in the both sides of upper collecting chamber and lower header, there is respectively connection mouthful, heating tube is communicated with by connection mouthful at upper collecting chamber and lower header both sides, lower header connects steam pipe by air inlet pipe, and upper collecting chamber connects escape pipe.
Especially, needle valve is installed in air inlet pipe.
Especially, on air inlet pipe and escape pipe, thermometer is installed.
Especially, in the both sides of upper collecting chamber and lower header, have respectively 4-18 Volleyball Association mouth, heating tube is arranged mouthful connection of 4-18 connection at upper collecting chamber and lower header 3 both sides by this, each section of whole formation of heating tube spiral tube structure.
Especially, upper collecting chamber and lower header are single layer structure.
Especially, upper collecting chamber and lower header are installed in boiler furnace place rear arch furnace wall.
Advantage of the present utility model and effect: adopt the two-way heating tube spiral string that arranges to connect lower heat-collecting box, and be installed in boiler furnace place rear arch furnace wall, steam is heated again, significantly improve steam heat collection and heat-collecting temperature again, then heating-up temperature equalization stable, improve collecting efficiency and equipment job stability, reduce costs, when increasing, the heat capacity of boiler saves fuel effect obvious, facilitate durable safety, practical, there is promotion prospect.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment 1 structural representation.
Reference numeral comprises: heating tube 1, upper collecting chamber 2, lower header 3, needle valve 4, air inlet pipe 5, escape pipe 6, thermometer 7, steam pipe 8.
The specific embodiment
The utility model comprises: heating tube 1, upper collecting chamber 2, lower header 3, air inlet pipe 5, escape pipe 6 and steam pipe 8.
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment 1: as shown in Figure 1: upper collecting chamber 2 and lower header 3 are settled up and down, in the both sides of upper collecting chamber 2 and lower header 3, there is respectively connection mouthful, heating tube 1 is communicated with by connection mouthful at upper collecting chamber 2 and lower header 3 both sides, and lower header 3 connects steam pipe 8 by air inlet pipe 5, and upper collecting chamber 2 connects escape pipe 6.
In aforementioned, needle valve 4 is installed in air inlet pipe 5.
In aforementioned, on air inlet pipe 5 and escape pipe 6, thermometer 7 is installed.
In aforementioned, in the both sides of upper collecting chamber 2 and lower header 3, have respectively 4-18 Volleyball Association mouth, heating tube 1 is arranged mouthful connection of 4-18 connection at upper collecting chamber 2 and lower header 3 both sides by this, especially, and each section of whole formation spiral tube structure of heating tube 1.
In aforementioned, heating tube 1 effectively increases upper collecting chamber 2, lower header 3 heating surface areas.
In aforementioned, upper collecting chamber 2, lower header 3 are single layer structure.Heating tube 1 inwall is 15CrMoG alloy, is suitable for each heated structure in the boiler of operating temperature≤560 ℃, or for the non-heated structure of boiler of operating temperature≤560 ℃.
In the utility model, be installed in boiler furnace place rear arch furnace wall, the equalization stable of heating-up temperature again of boiler high-enthalpy steam superheating device, has cancelled the technique that heating tube outer wall adds cast alloy heat-resisting cast iron, reduces costs.
In the utility model, upper collecting chamber 2 is exported and is connected for superheated steam, and lower header 3 is that boiler saturated steam pipe connects.
The utility model is installed in boiler furnace place rear arch furnace wall, and 2 of lower header 3 and upper collecting chambers are respectively by being positioned at corresponding two mouth UNICOM of the Volleyball Association heating tubes 1 in both sides.The auxiliary thermal-arrest that further improves vapor (steam) temperature heats up, and lower header 3 one end are that steam pipe 8 is connected by air inlet pipe 5 and boiler saturated vapor outlet, and upper collecting chamber 2 output superheated steams and steam outlet pipe 6 are connected, and enter sub-cylinder, form the steam operation circulatory system.
Due to, the visible ray heat energy of steam coal burning, boiler hot radiation heating and the main heat energy that improves furnace temperature, another part black light, among the heat energy of infrared ray and other ray light, long wave part heat energy is participated in boiler hot radiation heating and is improved furnace temperature effect, and the most consumables of shortwave heat energy lose.The utility model is arranged on boiler furnace place, low-temperature saturated steam fully absorbs shortwave heat energy by lower header 3, heating tube 1, upper collecting chamber 2, can obtain heat temperature raising, now boiler saturated vapour pressure 0.6MPa is constant, exit superheat steam temperature can reach 220 ℃～250 ℃, and 158 ℃ of saturated vapor temperature during boiler export original steam pressure 0.6MPa, the heat capacity of boiler increases, vapor (steam) temperature improves 29%～47%, economize on coal 16%, boiler heat supplying ability has increased, and boiler thermal output has improved.
