Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the schematic cross-section of injection tube and diversion pipe in the utility model.
Specific embodiment
As depicted in figs. 1 and 2, a kind of house-bag duster for high temperature using iron-chromium-aluminum felt of the utility model, including
Cabinet 1 is separated into air-purifying chamber 3 and lower separation chamber 4 by card 2 inside cabinet 1, upper air-purifying chamber 3 and sack cleaner out
Air port 5 is connected to, and is hung with several filter bags 6 being connected with upper air-purifying chamber 3 on card 2, is equipped with above filter bag 6 for deashing
Spraying and blowing organ, 1 bottom of cabinet is provided with the ash bucket 7 being connected to lower separation chamber 4, offers air inlet 8 and discharge port on ash bucket 7
9, air inlet pipe is installed, discharge port 9 is located at 7 bottom of ash bucket, and discharge port 9 is equipped with for unloading grey revolving valve 10, institute at air inlet 8
The material of filter bag 6 is stated using iron-chromium-aluminum felt, the use temperature of iron-chromium-aluminum felt can reach 1000 DEG C, and have good
Gas permeability and excellent hot shock resistance, precision is controllable, corrosion-resistant, fibrofelt can setback, solderable, be particularly suitable for applying
In 500-1000 DEG C of gas cleaning at high temperature field.
Spraying and blowing organ includes gas bag 11, injection tube 12 and electromagnetic impulse valve 13, and injection tube 12 is connected to gas bag 11, electromagnetism arteries and veins
Valve 13 is rushed to be mounted in injection tube 12, the downside of injection tube 12 is equipped with several blowing mouths 14 corresponding with 6 sack of filter bag,
Vertically arranged diversion pipe 15 is installed on blowing mouth 14, the compressed gas sprayed from blowing mouth 14 can be made vertically downward, prevented
Blast pass skew breaks through filter bag 6, and the drainage side pipe 16 for avoiding 6 sack of filter bag from condensing, drainage are communicated on diversion pipe 15
The setting of side pipe 16 there are two and about diversion pipe 15 it is symmetrical, drainage side pipe 16 be obliquely installed and drain side pipe 16 and diversion pipe 15 it
Between angle be α, it is 15-60 ° that the angle for draining between side pipe 16 and diversion pipe 15, which is α,.
Drainage side opening 17 is offered on diversion pipe 15, drainage side opening 17 is located at 16 top of drainage side pipe, and drainage side opening 17 is
Even numbers is a and symmetrical two-by-two.When compressed air high speed passes through diversion pipe 15, the high-temperature cleaning gas in upper air-purifying chamber 3 can pass through
Drainage side opening 17, which is drained in diversion pipe 15, to be converged, and drainage effect is enhanced.
Since the compressed gas temperature used when deashing is lower, high-temperature flue-gas to be clean is higher, works as compressed gas
When spraying into filter bag 6 by injection tube 12, compressed gas discharges suddenly, 6 sack ambient temperature dramatic decrease of filter bag, due to temperature
The rapidly reduction of difference and pressure, temperature 6 mouthfuls of dew condensation phenomenons easy to form of higher filter bag, the water conservancy diversion being arranged in the utility model
Pipe 15 and drainage side pipe 16 are conducive to that sack is avoided to condense, principle are as follows: blowing mouth 14 of the compressed gas high speed from injection tube 12
When by diversion pipe 15, since diversion pipe 15 is connected to drainage side pipe 16, according to the smaller principle of the bigger pressure of fluid flow rate, on
High-temperature cleaning gas in air-purifying chamber 3 is drained to diversion pipe 15 and is converged, and the gas temperature after converging is relatively high, will not lead again
6 sack ambient temperature dramatic decrease of filter bag is caused, can effectively avoid moisture condensation.
The compressed gas stored in gas bag 11 is nitrogen.The compressed air quality for being usually used in blowing is poor, aqueous oil-containing, meeting
Moisture condensation is aggravated, and nitrogen mass is good, can reduce moisture condensation may.
Heat-preservation cotton 18 is coated on the lateral wall of cabinet 1 and ash bucket 7.Heat-preservation cotton 18 can play insulation effect, when high temperature cigarette
After gas enters in cabinet 1, dew condensation phenomenon will not occur because 1 internal-external temperature difference of cabinet is larger.
Corrosion-inhibiting coating is coated on the inner sidewall of cabinet 1 and ash bucket 7, high-temperature flue gas complicated component generally has corrosivity,
Painting anticorrosion coating can extend service life of equipment.
There is wind deflector 19 in 8 installed in front of air inlet in cabinet 1.It is equipped with gap between wind deflector 19 and air inlet 8, keeps out the wind
Plate 19 can obstruct coarse dust.
Level-sensing device 20 is installed on ash bucket 7.When the dust accretions in ash bucket 7 are to when being more than 20 position of level-sensing device, material
Position meter 20 will call the police, and operating personnel is prompted to unload ash in time.
When to high temperature fume dust removal, high-temperature flue gas to be processed enters ash bucket 7, high-temperature flue gas through the air inlet 8 of ash bucket 7
It is collided with the wind deflector 19 installed at air inlet 8 is closed in cabinet 1, coarse dust is fallen directly into ash bucket 7, remaining fine particle
Dust moves upwards with high-temperature flue gas and reaches filter bag 6, due to the inertia of filter media fibre and fabric, diffusion, barrier, hook, electrostatic
The effects of, dust is escaped outside bag, is discharged through air outlet 5 by detention, purified gas.When deashing, electromagnetic impulse valve 13 works,
Compressed gas from gas bag 11 with the time of extremely short rush in order through electromagnetic impulse valve 13, compressed gas is through leading in injection tube 12
The induction of flow tube 15 is located at the high-temperature cleaning gas in upper air-purifying chamber 3 and enters filter bag 6, forms air wave, makes filter bag 6 by the sack bottom of to
Portion generates expansion and impact vibration sharply, causes very strong deashing to act on, shakes off the dust on filter bag 6.
The present embodiment not makes any form of restriction the shape of the utility model, material, structure etc., all foundations
The technical essence of the utility model any simple modification, equivalent change and modification to the above embodiments, belong to this reality
With the protection scope of new technique scheme.
