Through the saturated steam cleaning superheater, continuously supplied medium-temperature medium-pressure steam is converted into discontinuously supplied slightly-superheated steam through the heat exchanger; fuel gas is not consumed, by-products recycled in a factory are fully utilized, and work is reliable; compared with other steam superheating modes, the saturated steam cleaning superheater is low in electricity consumption, long in service life and reliable in operation, and operation cost is reduced; the total investment is small, and the saturated steam cleaning superheater is very practical.
Description
Technical field
The utility model relates to a kind of steam heating device, is specifically related to the clean superheater of a kind of saturated vapor.
Background technology
Natural gas is as a kind of clean energy resource, receive increasing concern and use, natural gas is widely used in productive life as fuel, society to clean energy resource demand also in continuous expansion, in recent years, field is " gas is waste " a plurality of provinces and cities that sweep over the country on a large scale, and the difficult problem that natural gas supply is in short supply is put in face of people again.Along with the short supply of natural gas, various places are heightened Gas Prices one after another.In iron and steel enterprise, the use of natural gas is comparatively general and gas consumption is also larger, reduces that to use natural gas be to alleviate " gas is waste " effective means, can avoid because the stopping production that combustion gas shortage causes simultaneously.The packaged boiler using in iron and steel enterprise is natural gas motorcar rich and influential family, and therefore, the operation that how to reduce packaged boiler just seems especially important.
At present, packaged boiler is used to the steam-supplying system of vacuum refining mostly.Vacuum refining, to the strict requirement of being supplied with of steam, is interrupted and uses, responds rapid, parameter stability.Micro-superheated steam that packaged boiler produces can meet above requirement.But packaged boiler needs the contour calorific value fuel gas of natural gas fuel, the supply of high heating value combustion gas in iron and steel enterprise is very in short supply.In order both to meet the requirement of vacuum refining to steam, can solve again high heating value gas supply problem in short supply in iron and steel enterprise.The utility model has designed the clean superheater of a kind of saturated vapor solving the problems of the technologies described above.
Utility model content
The technical solution of the utility model is as follows:
A kind of saturated vapor cleans superheater, storage heater air inlet in this device is connected with medium temperature and medium pressure superheated steam input pipe, its gas outlet is connected with the clean device entrance of filter by saturated vapor efferent duct, filtering clean device outlet derives the saturated vapor after processed and through efferent duct, draws the entrance that leads to heat exchanger, and the outlet of heat exchanger is connected and causes equipment for vacuum refining with micro-overheated steam pipe of deriving micro-superheated steam;
Another pass of medium temperature and medium pressure superheated steam input pipe is connected to control valve group, and draws and be connected to heat exchanger after control valve group regulates.
The condensate water producing in heat exchanger drains into regular unloading container by the condensate line of its bottom, condensate water in blowdown system is introduced softened water tank entrance by pipeline after dilatation cooling, is connected with filling pipe and the condensate water after softening is pumped into the small pump in storage heater between softened water tank outlet and storage heater.
Filter knot device bottom is provided with outer evacuated tube of drawing.
As shown from the above technical solution, technique effect of the present utility model is as follows:
1, the utility model is converted to the steam of medium temperature and medium pressure parameter without interruption the micro-superheated steam that is interrupted supply through heat exchanger.
2, the utility model does not consume combustion gas, makes full use of the byproduct that plant area reclaims, and reliable operation.
3, the utility model and other steam superheating mode ratio, power consumption is low, has reduced operating cost, and equipment life is long, and reliable.
4, the utility model overall investment is few, has very strong practicality.

The specific embodiment
A kind of saturated vapor cleans superheater, it is characterized in that, storage heater 1 air inlet in this device is connected with medium temperature and medium pressure superheated steam input pipe, its gas outlet is connected with clean device 2 entrances of filter by saturated vapor efferent duct, filtering clean device 2 outlets derives the saturated vapor after processed and through efferent duct, draws the entrance that leads to heat exchanger, and the outlet of heat exchanger 3 is connected and causes equipment for vacuum refining with micro-overheated steam pipe of deriving micro-superheated steam.
Another pass of medium temperature and medium pressure superheated steam input pipe is connected to control valve group 7, and draws and be connected to heat exchanger 3 after control valve group 7 regulates.
The condensate water producing in heat exchanger 3 drains into regular unloading container 4 by the condensate line of its bottom, condensate water in blowdown system 4 is introduced softened water tank 5 entrances by pipeline again through dilatation cooling, is connected with filling pipe and the condensate water after softening is pumped into the small pump 6 in storage heater 1 between softened water tank 5 outlets and storage heater 1.
Filter knot device 2 bottoms are provided with outer evacuated tube of drawing.
Below in conjunction with Fig. 1, the utility model operation principle is described.
Referring to Fig. 1, medium temperature and medium pressure superheated steam Z0 is connected to the steam inlet of storage heater 1, through storage, from the steam (vapor) outlet of storage heater 1, enters the clean device 2 of filter.In the clean device 2 of filter, saturated vapor Z1 carries out after processed, sends into heat exchanger 3 and carries out heat exchange.Another branch road of medium temperature and medium pressure superheated steam Z0 is connected to heat exchanger 3, in heat exchanger 3, carries out heat exchange with the saturated vapor Z1 through processed.Saturated vapor Z1 changes micro-superheated steam Z2 into and delivers to user; Medium temperature and medium pressure superheated steam Z0 changes condensate water SF into and delivers to regular unloading container 4 dilatation coolings, and condensate water flows into softened water tank 5, through small pump 6, returns storage heater 1 as a part for system water supplement.
Referring to Fig. 1, with certain flow medium temperature and medium pressure superheated steam Z0 without interruption, enter the steam inlet of described storage heater 1, when user does not use steam, medium temperature and medium pressure superheated steam Z0, in the interior storage of described storage heater 1, changes saturated vapor into; When user uses steam, from described storage heater 1, emit saturated vapor clean device 2 dehydrations after filtration, in heat exchanger 3, be heated and be converted to micro-superheated steam and be sent to user; When user does not use micro-superheated steam, described storage heater 1 continues to store, and so circulation can make satisfied interruption of steam without interruption use.
Medium temperature and medium pressure superheated steam Z0 steam superheat is too high, can not meet the requirement that user uses micro-superheated steam, native system is except being interrupted steam supply without interruption with outdoor, also by controlling superheated steam Z0 control valve group 7, adjust the outlet of micro-superheated steam, also can play the object of adjusting load.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, the common variation that those skilled in the art carries out within the scope of technical solutions of the utility model and replacement all should be included in protection domain of the present utility model.
