Description
Technical field
The present invention relates to the waste heat boiler Apparatus and method for, relate to float glass exhaust-heat boiler ash removing equipment and method more specifically.
Background technology
The forming process of float glass is to finish in the molten tin bath that feeds protective gas.Melten glass continuously flows into from tank furnace and swims on the big tin liquor surface of relative density, under gravity and capillary effect, glass metal spread out, shakeout, form that upper and lower surface is smooth on the tin liquor face, sclerosis, cooling back drawn the transition roller platform.The roller turn of roller platform is pulled out molten tin bath to glass tape and is entered annealing kiln, through annealing, cutting, just obtains the plate glass product.
When the energy of the flue gas that utilizes waste heat boiler recovery glass kiln to produce, heating surface, it is constantly accumulation dust of heat exchanger tube row, thereby cause the reduction of pyroconductivity, the float glass exhaust-heat boiler dust stratification has a strong impact on the boiler heat exchange efficiency, conventional online purge mode such as vibration dust-cleaning, steam soot blowing, the steel ball deashing all has very important shortcoming.Vibration dust-cleaning is not suitable for float glass exhaust-heat boiler, can not effectively clear up the dust stratification on the panel-pipe of heating surface; Steam soot blowing is concerning float glass exhaust-heat boiler, and the dust stratification in its sphere of action can be cleaned out, but it is a lot of to blow grey dead angle, still needs the blowing out cleaning; In the steam soot blowing work, the pressure oscillation in the waste heat boiler is big, and the glass thread furnace pressure is had certain influence; The steam soot blowing working media is a superheated steam, can increase the humidity of heat boiler outlet, increases cold end corrosion; Relative cogeneration unit, the steam soot blowing cost is very high.The steel ball deashing is concerning float glass exhaust-heat boiler, and its ash-removal effect is fine, but shortcoming clearly, and very big to the wearing and tearing of panel-pipe of heating surface, the life-span of boiler has a greatly reduced quality; The losing quantity of steel ball in service is big, and cost is higher.

Description of drawings
Fig. 1 is a structural representation of the present invention;
Parts, position and numbering among the figure: waste heat boiler 1, heating surface 2, pulse gas generating means 3, spout 4.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
As shown in Figure 1, float glass exhaust-heat boiler ash removing equipment of the present invention comprises that waste heat boiler 1, waste heat boiler 1 are provided with pulse gas generating means 3, the heating surface 2 of the spout 4 of pulse gas generating means 3 in waste heat boiler 1.Pulse gas generating means 3 can adopt compressed air generator, and the device of fuel gas pulse ash blower device and so on, pulse gas generating means 3 can be contained in outside the waste heat boiler 1, also can be contained in the waste heat boiler 1, decide according to concrete condition.When blowing ash, pulse gas generating means 3 produces pulse gas, and pulse gas acts on the heating surface 2 by spout 4 ejections, makes that the dust on the heating surface 2 breaks away from, and this moment, waste heat boiler 1 interior flue gas was taken away floating dust.
For the ease of installation and maintenance, as Fig. 1, pulse gas generating means 3 is arranged on the outer wall of waste heat boiler 1.
Very responsive to furnace pressure in the float glass process, if pulse gas generating means 3 breaks down, the pressure that air pulse produces may cause the pressure oscillation of glass kiln.For this reason, as shown in Figure 1, spout 4 opening directions are identical with flue gas flow direction, and the action direction of air pulse is identical with the flue gas flow path direction, and are promptly opposite with glass kiln direction, alleviate the effect of air pulse to the glass kiln with this.
The sphere of action of air pulse is limited, all can effectively clear up dust for making each heating surface 2, as shown in Figure 1, the flue gas direction of coming of each heating surface 2 in the waste heat boiler 1 is provided with spout 4, and a spout 4 corresponding a plurality of pulse gas generating means 3 or a plurality of spout 4 corresponding pulse gas generating means 3 can be set this moment as the case may be.
As shown in Figure 1, spout 4 is corresponding one by one with heating surface 2, and spout 4 is corresponding one by one with pulse gas generating means 3.At this moment, blow in the grey process, only need a control impuls gas generating unit 3 to get final product in control, when heating surface 2 dust stratifications not simultaneously, pulse gas generating means 3 can be selected different power for use according to different heating surface 2, to satisfy various situations.
In order better to blow ash and process control, pulse gas generating means 3 is the fuel gas pulse ash blower device.
Float glass exhaust-heat boiler ash removal method of the present invention may further comprise the steps:
A, produce pulse gas by the pulse gas generating means 3 that is arranged on the waste heat boiler 1, the dust that this pulse gas blows on the heating surface 2 makes it break away from heating surface 2;
B, the dust that utilizes waste heat boiler 1 interior flue gas will break away from heating surface 2 are discharged from exhanst gas outlet.
Produce pulse gas multiple mode is arranged, periodically burn such as combustion gas, air pump is periodically worked, pulse gas has the short time, the characteristics that pressure is big can be removed the dust on the heating surface 2 completely, and its action time is short, its gross energy is low, and the pressure oscillation of its generation is difficult to influence glass kiln furnace pressure.
Very responsive to furnace pressure in the float glass process, if pulse gas generating means 3 breaks down, the pressure that air pulse produces may cause the pressure oscillation of glass kiln.For this reason, in steps A, described pulse gas generating means 3 is the fuel gas pulse ash blower device, and this fuel gas pulse ash blower device produces the pulse gas identical with flue gas flow direction, and is promptly opposite with glass kiln direction, avoids the effect of air pulse to the glass kiln with this.
In steps A, under the situation that has a plurality of pulse gas generating means 3, if pulse gas generating means 3 starts simultaneously, the dust that then previous heating surface 2 is blown down will influence next heating surface 2, blow grey efficient reduction thereby make, for overcoming the above problems following technology is set, in steps A, pulse gas generating means 3 produces pulse gas successively along the trend of flue gas, finishes until deashing so repeatedly.Behind first heating surface 2 of cleaning flue gas flow direction, dust is restarted second heating surface, 2 pairing pulse gas generating means 3 this moment along with second heating surface 2 of flue gas flow direction, and the dust under the cleaning is along with the 3rd heating surface 2 of flue gas flow direction, by that analogy, finish until cleaning.
In steps A, need to regulate flow velocity to the 6～7.5m/s of flue gas in the waste heat boiler 1, at this moment, and the mobile effect of flue gas with cancellation pulses gas, thus prevent that the pressure influence that pulse gas produces from arriving the glass kiln.
By the following examples foregoing of the present invention is described in further detail again.But this should be interpreted as that the above-mentioned theme of the present invention only limits to following example.All technical schemes that realizes based on foregoing of the present invention all belong to scope of the present invention.
