Description
Technical field
The utility model relates to a kind of energy-saving water-saving device of construction material production field, is specifically related to a kind of still kettle afterheat steam recycling device.
Background technology
At present, building trade construction adopts cement pouring frame formula structure, needs a large amount of materials for walls to carry out filling and wall constructed.Wherein, autoclave aerated concrete building block is a kind of novel energy-conserving and environment-protective material, current building material industry generally adopts still kettle that air-entrained concrete building block green compact are carried out steam pressure reaction, need high pressure and 180 DEG C of high temperature saturated steams of about 1.6MPa in still kettle, the heat-insulation pressure keeping time is generally 6 hours.But after steam pressure reaction terminates, if the high temperature and high pressure steam in direct pressure relief blow still kettle, the waste of a large amount of heat energy and water will be caused.
In prior art, about not yet considering the recycling of afterheat steam in autoclave aerated concrete building block production equipment, steam boiler energy loss is large, and heat loss is large, and production cost is high.
Utility model content
The utility model, for the deficiency of existing production technology, is designed a kind of still kettle afterheat steam recycling device, can be made full use of the high temperature and high pressure steam waste heat of still kettle by this device, have remarkable energy-saving and water-saving effect.
A kind of still kettle afterheat steam recycling device, it is characterized in that, this device forms a complete afterheat steam cyclic utilization system by Steam Heating tank, water pump, water vapor transmission pipeline, valve, heating installation bag, condenser; The feature of described Steam Heating tank is to be made up of water tank and built-in heat conduction coil pipe, wherein: water tank is for storing demineralized water, and under heat conduction coil pipe, port communicates with the exhaust outlet of still kettle, the rest heating installation bag of room of upper port and foaming is connected; Described water pump, it is connected with water tank, and the demineralized water utilizing pump handle to be heated by steam pumps in the container of steam boiler; Described steam pipeline and valve, waterpipe is used for the connection between softening water tower, water tank, water pump, steam boiler container, forms the passage that water transports; Steam pipe road is used for still kettle exhaust outlet, connection between heat conducting disk tube inlet and heating installation bag, forms the passage of vapor flow; Valve respectively arranges one at still kettle exhaust outlet and water tank entrance, is respectively used to the discharge rate and the water tank inflow that control still kettle afterheat steam; Heating installation bag leading portion arranges a gas valve, and rear end arranges a gas overflow valve; Be connected with gas overflow valve by pipeline after described condenser is placed in heating installation bag, what make heating installation bag crosses pressurized overflow steam-condensation Cheng Shui, reusable edible after collecting.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model device.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail, but not as to restriction of the present utility model.
As shown in Figure 1, brass spiral coil (the internal diameter 10mm that described heat conduction coil pipe 2 adopts thermal conductivity factor high, wall thickness 1.5mm), ensure that steam-heated brass tube and demineralized water carry out sufficient heat exchange, due to demineralized water non-scaling, corrosion-free, ensure that Steam Heating tank has the feature of long service life.
During actual motion, Open valve 4, puts into Steam Heating tank 1 the demineralized water in water tower 3; The afterheat steam pressure that still kettle terminates steam pressure is about 1.6MPa, temperature about 180 DEG C, after residual steam being imported another still kettle on side, Pressure Drop is to 0.7MPa, temperature about 150 DEG C, at this moment still kettle air bleeding valve 9 is opened, by the lower inlet 5 of heat conduction coil pipe, steam is imported heat conduction coil pipe 2, to the demineralized water heating in heating tank 1; Open heating installation bag 10 front end valve 12, the vapours (may contain a small amount of condensed water) after catching a cold imports heating installation bag 10 by the upper end outlet 6 of heat conduction coil pipe 2 by pipeline simultaneously; When the pressure in heating installation bag 10 is greater than oil pressure relief (be generally 0.2MPa, can regulate according to the temperature requirements of room of resting) of rear end valve 13 setting, overflow valve 13 overflows steam automatically, enters condenser 14 and is condensed into water, can recycle; When the temperature in Steam Heating tank reaches 80 DEG C (detecting with temperature measuring device), close still kettle air bleeding valve 9, stop heating; Open water pump 7, the demineralized water of heating is extracted in boiler vessel 11, achieves the significantly reduction of energy consumption like this.
This device adopts following steps to realize recycling of still kettle afterheat steam aborning:
(1) open water tank and enter penstock, allow the softening cold water in water tower flow in water tank, make it complete submergence heat conduction coil pipe or rise to the water level of setting.
(2) open the air bleeding valve of still kettle, the afterheat steam of still kettle is imported the lower inlet of heat conduction coil pipe, vapours carries out heat exchange by the cold water in heat conduction coil pipe and water tank, and the cold water in water tank is heated; Open the forward end gas valve of heating installation bag simultaneously, make the pipeline junction of heat conduction coil pipe upper end outlet and heating installation bag in unimpeded state, heating installation bag tail end is provided with a gas overflow valve, the automatic overflow when pressure reaches setting value, keeps heating installation bag pressure power to be substantially in constant.
(3) when the water temperature in water tank rises to 80 DEG C, the air bleeding valve of still kettle is closed, the gas valve of turning off steam bag front end subsequently.
(4) start water pump, the hot water in water tank is pumped in steam boiler container.
Above-mentioned 4 steps complete a recycling residual heat.Repeat the recycled for multiple times that above-mentioned steps can realize still kettle afterheat steam.
Compared with prior art, still kettle afterheat steam recycling device described in the utility model, reaches following effect:
Cold water in steam heating chamber can be preheated to 80 DEG C, energy-conservation 50 ~ 60% (changing to some extent depending on temperature difference), continue to recycle after water vapor condensation, Water Sproading utilization rate reaches more than 70% simultaneously.
Above-mentioned explanation illustrate and describes some preferred embodiments of the present utility model, but as previously mentioned, be to be understood that the utility model is not limited to the form disclosed by this paper, should not regard the eliminating to other embodiments as, and can be used for other combinations various, amendment and environment, and can in utility model contemplated scope described herein, changed by the technology of above-mentioned instruction or association area or knowledge.And the change that those skilled in the art carry out and change do not depart from spirit and scope of the present utility model, then all should in the protection domain of the utility model claims.
