Description
Technical field
The utility model belongs to electrical equipment technical field, more particularly to a kind of soot blowing dress with double protection
It sets.
Background technology
In the process of running, fouling of heating surface, coking are common phenomena to electric power unit, and fouling of heating surface, coking can cause
Heating surface heat transfer coefficient reduces, and causes the reduction of unit efficiency and the waste of the energy.
Steam soot-blower is using the steam blowing heating surface of certain pressure, temperature, and cleaning heating surface surface is accumulated
Loose dust stratification.But if the valve tightness on vapor transmission branch pipe is undesirable, in not soot blowing, aqueous steam is also
It can enter in stove and blow loss is continued to unit heating surface, since soot blower does not work at this time, therefore blow loss point is fixed, simultaneously because steaming
Vapour band water, generates cold shock, long-play does not find that then heating surface will produce booster, cause machine in time again to heating surface
The improper stoppage in transit of group.
Unit heating surface another major reason impaired based on steam soot-blower is：After preceding soot blowing operation
A small amount of steam is had to stockpile in vapor transmission branch in-tube condensation, though need first heating coil to reduce the thermal stress of pipeline before soot blowing,
Be heating coil can only pre-warm steam conveying main pipe, and because no steam flows cannot achieve pre-warm in vapor transmission branch pipe, this causes
Condensed water before can not be eliminated, and again when soot blowing, steam can carry condensed water and touch heating surface, this also results in heated
Face is impaired.
Utility model content
The technical problem to be solved by the utility model is to：Steam soot-blower in valve leaks or pipeline due to condensing
The presence of water and to heating surface generate blow loss,
Unresolved above-mentioned technical problem, the utility model provide it is a kind of having effects that the soot blower of double protection, wrap
Include soot blower, steam delivery branch pipe, steam conveying main pipe, valve, temperature element, temperature indicator, cable, vacuum extractor,
Vacuum tube,
The output end of steam delivery branch pipe is connected with soot blower, and input terminal and the steam of steam delivery branch pipe convey main pipe
Be connected, steam delivery branch pipe is equipped with the valve of control steam circulation, be located in steam delivery branch pipe valve and output end it
Between be equipped with temperature element, the signal output end of temperature element is connected by cable with the signal input part of temperature indicator,
Not soot blowing or when heating coil, can discover whether the size of valves leakage and interior leakage degree by observing temperature,
One end of vacuum tube is connected with vacuum extractor, the other end and valve of vacuum tube to the steam between soot blower
Delivery branch pipe is connected,
Before starting soot blowing, by the remaining condensed water in steam delivery branch pipe or even soot blower by way of vacuumizing
It is siphoned away by vacuum tube, avoids this partial condensation water and directly hit, touch heating surface,
Wherein, temperature element is temperature thermocouple, and the distance apart from valve is 70mm,
In addition, soot blower further includes alarm, signal that the signal output end of temperature element passes through cable and alarm
Input terminal is connected, and when alarm monitors that temperature is more than alarming value, sends out alarm signal.
Description of the drawings
Fig. 1 is the structural schematic diagram with the soot blower of double protection of the utility model, wherein 1-soot blowing
Device, 11-flushing air outlets, 2-steam delivery branch pipes, 3-steam conveying main pipe, 4-valves, 5-temperature elements, 6-temperature are aobvious
Show device, 7-cables, 8-vacuum extractors, 9-vacuum tubes, 10-alarms.
Specific implementation mode
It is a kind of to have effects that the soot blower of double protection, structure are as shown in Fig. 1：It is conveyed including soot blower 1, steam
Branch pipe 2, steam conveying main pipe 3, valve 4, temperature element 5, temperature indicator 6, cable 7, vacuum extractor 8, vacuum tube 9,
Wherein, the output end with soot blower 1 of steam delivery branch pipe 2 is connected, the input terminal and steam of steam delivery branch pipe 2
Conveying main pipe 3 is connected, and steam delivery branch pipe 2 is equipped with the valve 4 of steam circulation in control pipe, in steam delivery branch pipe 2, position
Temperature element 5 is equipped between 2 output end of valve 4 and steam delivery branch pipe, the signal output end of temperature element 5 passes through cable 7
It is connected with the signal input part of temperature indicator 6, temperature element 5 is temperature thermocouple, and the distance apart from valve 4 is 70mm,
Not soot blowing or when heating coil, can discover whether the size of valves leakage and interior leakage degree by observing temperature,
Alarm 10 is additionally provided in soot blower, the signal output end of temperature element 5 passes through cable 7 and alarm 10
Signal input part is connected, and when alarm monitors that temperature is more than a certain numerical value (alarming value), can directly send out alarm signal, draw
Play the enough attention of people；
One end of vacuum tube 9 is connected with vacuum extractor 8, the other end of vacuum tube 9 with positioned at valve 4 and soot blower 1
Between that section of steam delivery branch pipe 2 be connected, before starting soot blowing, by this section of steam conveying branch by way of vacuumizing
It can not be siphoned away by vacuum tube 9 by the remaining condensed water that heating coil removes in pipe 2 or even soot blower 1, avoid this partial condensation water
It directly hits, touch heating surface.
