Description
Technical field
The present invention relates to energy-conserving and environment-protective technical fiel, the smoke and waste steam boiler of dust stratification is specially prevented.
Background technology
In the industrial production, various kilns are used, it can produce substantial amounts of high-temperature flue gas, and these high-temperature flue gas contain cigarette
Dirt, it is necessary to after cooling down dedusting discharge, and cooling down these flue gases typically has two methods：One kind is to absorb flue gas using cooling medium
Heat, heat absorption heating after be directly discharged into air；Another kind is to absorb the heat of flue gas and is industrial production using these heats
Thermal source is provided with life, mass energy can be saved, and is utilized for the fume afterheat in second of cooling means preferably square
Method is exactly to use smoke and waste steam boiler, and it can produce afterheat steam, and smoke and waste steam boiler cools down and remaining as high-temperature flue gas
Heat utilization, generally used in high-temperature flue gas UTILIZATION OF VESIDUAL HEAT IN dust pelletizing system at home, but design and use for many years, hair
Flue dust in existing flue gas directly affects the using effect of smoke and waste steam boiler, i.e., due to flue dust property caused by each stove not
Together, also different, some meetings dust stratification on evaporator heat exchange element is influenceed on the heat exchange element of evaporator in smoke and waste steam boiler
Even block exhaust gases passes, some evaporator heat exchange elements by flue dust erosive wear, also just reduce flue gas cooling effectiveness and
Steam production, the service life of smoke and waste steam boiler is shortened, so as to influence the normal operation that fume afterheat utilizes dust pelletizing system.
The content of the invention
In view of the above-mentioned problems, the invention provides the smoke and waste steam boiler for preventing dust stratification, it can reduce flue dust to more than flue gas
The influence of the heat exchange element of evaporator in heat boiler, ensure smoke and waste steam boiler using effect, improve flue gas cooling effectiveness and production
Vapour amount, extend smoke and waste steam boiler service life, ensure that fume afterheat utilizes the normal operation of dust pelletizing system.
Its technical scheme is such：It include evaporator and be sequentially connected from top to down upper box, lower box,
Ash bucket, it is characterised in that the evaporator is arranged in the upper box, and drum, the drum are provided with above the upper box
The evaporator is correspondingly connected to, Whirlwind cyclone is provided with the lower box, the discharge tube end of the Whirlwind cyclone is communicated to institute
State in upper box, the ash hole of the Whirlwind cyclone connects with the ash bucket, exhanst gas outlet is provided with the upper box, under described
Smoke inlet is provided with casing.
It is further characterized by：
The water inlet connection feed pipe of the drum sidepiece, the delivery port of bottom are connected with the water inlet of the evaporator, top
The steam (vapor) outlet connection steam supply pipe of side, the steam inlet of top opposite side are gone out by the steam of jet chimney and the evaporator
Mouth connection；
The Whirlwind cyclone is arranged in the lower box with in-line arrangement or staggered pattern, the rotation in the upper box
The discharge tube end of wind is located at below the evaporator.
The invention has the advantages that flue gas enters lower box by smoke inlet, and it is further separated into Whirlwind cyclone, flue gas edge
Whirlwind cyclone inwall from top to bottom makees spiralling, after inwall bottom is reached then upward, rotates up along axle center, most passes through afterwards
Discharge pipe is discharged, and flue gas is when rotating, and the flue dust in flue gas want inward wall shifting under the promotion of centrifugal inertial force
It is dynamic, the flue dust of inwall is reached under the collective effect of air-flow and gravity, is fallen into along internal face in ash bucket, has been reached the mesh of dedusting
, and it is that comparison is clean that the flue gas flowed in evaporator is expelled to by discharge pipe, so as to avoid the member that exchanged heat in evaporator
The dust stratification of part and abrasion, the problem of exhaust gases passes is even blocked, extend the service life of smoke and waste steam boiler, reduce flue gas
Collateral resistance, reduce operating cost, and the flue gas after dedusting is passed through in evaporator and carries out heat exchange, flue gas releases heat temperature
Degree reduces, and produces steam and be passed through the interior progress steam-water separation of drum, and the steam after separation can be sent to user, and water is stored in drum
For recycling, so as to improve the cooling effectiveness of flue gas and steam production.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
As shown in figure 1, the present invention includes evaporator 3 and the upper box 2 being sequentially connected from top to down, lower box 4, ash
Bucket 6, upper box 2 are flue gas collector-shoe gears, the passage as flow of flue gas；Evaporator 3 is that flue gas is exchanged with water equipment, installation
In upper box 2, for producing steam；Lower box 4 is the dedusting region as flue gas；The top of upper box 2 is provided with drum 1, vapour
Bag 1 is a compression thin cylinder metal structure, for making steam-water separation send out qualified steam, and stores setting for certain water
It is standby；Drum 1 is correspondingly connected to evaporator 3, i.e. the water inlet 7 of the sidepiece of drum 1 connects feed pipe, delivery port 8 and the evaporation of bottom
The water inlet connection of device 3, the steam (vapor) outlet 9 of top side connect steam supply pipe, and the steam inlet 10 of top opposite side passes through steam
Pipeline is connected with the steam (vapor) outlet of evaporator 3；Whirlwind cyclone 5 of the number in terms of ten ~ hundred is arranged in in-line arrangement or staggered pattern
In lower box 4, Whirlwind cyclone 5 is used as flue gas ash removal part, and the discharge tube end of Whirlwind cyclone 5 is communicated in upper box 2, and
The discharge tube end of Whirlwind cyclone 5 in upper box 2 is located at the lower section of evaporator 3, and the ash hole of Whirlwind cyclone 5 connects with ash bucket 6, top box
The upper end sidepiece of body 2 is provided with exhanst gas outlet 11, and the upper end sidepiece of lower box 4 is provided with smoke inlet 12.
The present invention workflow be：Flue gas enters lower box 4 by the smoke inlet 12 of lower box 4, then flue gas shunting
Into number, Whirlwind cyclone 5, flue gas carry out dedusting in Whirlwind cyclone 5 in terms of ten ~ hundred, and the clean flue gas after dedusting passes through the row of Whirlwind cyclone 5
Outlet pipe is discharged, and flue dust is separated in the presence of centrifugal inertial force with flue gas, and bottom is fallen into by the ash hole of the bottom of Whirlwind cyclone 5
Ash bucket 7, and periodically discharge, and entered by the clean flue gas of the discharge pipe of Whirlwind cyclone 5 discharge in upper box 2 and confluxed, subsequently into
Evaporator 3, discharge tube end are located at the lower section of evaporator 3, and clean flue gas flows from bottom to top in evaporator 3, while water passes through
Bear water pipe and enter drum 1, then the water in drum 1 is flowed into by delivery port 8 in the water inlet of evaporator 3, that is, evaporator 3
In interior heat exchanger tube, clean flue gas carries out indirect heat exchange by pipe wall of heat exchange pipe in evaporator 3 and the water being passed through in heat exchanger tube,
The heat of clean flue gas is released in evaporator 3, temperature, which reduces, to be cooled, and the heat that water absorbs cleanly flue gas produces steam,
Flue gas after cooling subsequently enters the top of upper box 2, is discharged by the exhanst gas outlet 11 of upper box 2, and caused steam is from steaming
The steam (vapor) outlet discharge of device 3 is sent out, drum 1 is entered by jet chimney, and carbonated drink is separated in drum 1, the steaming after separation
