As shown in Figure 2: the three groups of arrangements in 125 one-tenth upper, middle and lower of waste gas radiator element, waste gas radiator element 125 profiles are made acute triangle up, shift to install between last group of waste gas radiator element 125 and middle group of waste gas radiator element 125, between the two adjacent waste gas radiator element 125 during a waste gas radiator element 125 namely in the group just in time is arranged on and organizes, in like manner, organize down a waste gas radiator element 125 just in time be arranged between the two adjacent waste gas radiator element 125 in the group, purpose is for the drying area that is added to the stove coal, is beneficial to into coal and disperses landing.
As Fig. 1, Fig. 2, shown in Figure 3: that coal bunker 14 is set below waste gas radiator element 125, put at coal bunker 14 and to be provided with coal dust strainer 13, our image is called the coal dust respiratory organ, coal dust strainer 13 mainly comprises filter body 131, enter siphunculus 132 in the off-air, dust funnel 133, discharge siphunculus 134 in the off-air, off-air is discharged siphunculus 135 outward, enter siphunculus 132 in the off-air that leads to the top from the bottom filter body 131 peripheral being provided with, be provided with dust funnel 133 in filter body inside, dust funnel 133 leads to coal bunker 14, above dust funnel 133, be provided with and discharge siphunculus 134 in the off-air, the entrance 1321 that enters siphunculus 132 in the off-air is higher than the entrance 1341 of discharging siphunculus 134 in the off-air, discharging siphunculus 134 in the off-air is arranged on the strainer internal head cover 137, off-air is discharged siphunculus 135 outward and is arranged on the outer top cover 138 of strainer, is provided with steel fiber filtering net 136 outside strainer internal head cover 137 and strainer between the top cover 138.
As shown in Figure 3: enter siphunculus 132 in the off-air and be arranged in the filter body 131, enter siphunculus 132 in the off-air and in filter body 131, form cyclone structure with the interior 134 one-tenth vertical angles of siphunculus of discharging of off-air.
As shown in Figure 1: fly-ash separator 15 connects dehydration waste gas master and discharges tracheae 123, fly-ash separator 15 is existing dedusting technologies, fly-ash separator 15 comprises fly-ash separator housing 151, dust settling chamber 152, dehydration waste gas master discharges tracheae 123 leads to dust settling chamber 152, dust settling chamber 152 communicates with chimney 16 by induced draft fan 18 again, dust settling chamber 152 belows arrange flyash delivery pipe 153, described dust settling chamber 152 can be wet dedusting, also can adopt dry-method bag-type dust collecting, introduce wet dedusting herein, be provided with sprinkler head 154 above the dust settling chamber in fly-ash separator housing 151, dehydration waste gas master discharges tracheae 123 and submerges in the water in the dust settling chamber 152.
As Fig. 1; shown in Figure 2: hot waste gas enters the waste gas admission passage 1251 that tracheae 122 enters waste gas radiator element 125 inside by the hot waste gas master; dehydration waste gas exhaust channel 1252 by waste gas radiator element 125 inside enters dehydration waste gas master and discharges tracheae 123 again; discharge from chimney 16 after cleaning through the water layer in the dust settling chamber 152 again; flyash is stayed in the water layer and is regularly discharged by flyash delivery pipe 153 in the hot waste gas; both played hot waste gas had been purified; can reduce the hot waste gas exhaust temperature again; be beneficial to air draft; protection induced draft fan 18; reach the purpose of clean environment protection emission, the current country of response advocates the requirement of waste gas environment protection emission.
As shown in Figure 1 and Figure 2: the hot waste gas after the burning enters tracheae 122 typical temperatures at 700 ℃～800 ℃ entering the hot waste gas master, utilize the waste heat of hot waste gas self that waste gas radiator element 125 is heated, can lower the temperature to the hot waste gas after the burning, thereby the stove coal of going into through waste gas radiator element 125 is dewatered, can allow the water ratio of stove coal below 1% again, reach the effective utilization to the hot waste gas after the burning, save energy consumption.
As shown in Figure 1 and Figure 2: the discharge bucket 111 of bucket elevator 11 is arranged on material bin 1241 tops, goes into the bottom that stove coal transfer roller 17 is arranged on coal bunker 14.
As shown in figure 11: this example also comprises industry control center 90, the 90 pairs of induced draft fans that directly are electrically connected with it 18 in industry control center, goes into stove coal transfer roller 17 and bucket elevator 11 is controlled,
This example also includes stove coal electric controller 901, going into 901 pairs of stove coal electric controllers goes into stove coal transfer roller 17, induced draft fan 18 and bucket elevator 11 and controls automatically respectively, go into stove coal electric controller 901 and link with upper industry control center 90 again, realize going into the automatization of stove coal dewatering.Certainly from electric control theory, go into stove coal transfer roller 17, induced draft fan 18 and bucket elevator 11 in this example and also can directly be subjected to 90 controls of industry control center, so set into the restriction that stove coal electric controller 901 does not constitute this routine protection domain herein.
This example is gone into stove coal dewatering method principle:
1, industry control center 90 feeds stove coal electric controller 901 and spreads out of into stove coal transfer roller 17, induced draft fan 18 and bucket elevator 11 initiating signals, send in the dehydrator shell 121 top material bins 1241 by the stove coal of going into that bucket elevator 11 is finished proportioning earlier, by pan feeding vibratory screening apparatus 1242, blanking channel 1243, blanking vibratory screening apparatus 1244, waste gas radiator element 125 falls into coal bunker 14 at last;
2, hot waste gas being entered tracheae 122 by the hot waste gas master feeds in the waste gas admission passage 1251 of waste gas radiator element 125 inside, dehydration waste gas exhaust channel 1252 by waste gas radiator element 125 inside enters dehydration waste gas master and discharges tracheae 123 again, enters water layer in the dust settling chamber 152 again by induced draft fan 18 and discharges from chimney 16 after cleaning;
3, meanwhile, go into the stove coal fall into through waste gas radiator element 125 coal bunker 14 processes also can be to dehydrator shell 121 chambeies in and air in coal bunker 14 storehouses heat, heated air utilizes the heat buoyancy of self to enter in the off-air of coal dust strainer 13 and enters siphunculus 132 (as Fig. 3), be higher than the entrance 1341 of discharging siphunculus 134 in the off-air owing to enter the entrance 1321 of siphunculus 132 in the off-air, hot off-air forms whirlwind from top to bottom and enters discharge siphunculus 134 in the off-air, discharge siphunculus 135 dischargings outward finally by crossing steel fiber filtering net 136 and off-air, thereby the dust in the off-air because intercepting the dust funnel 133 that falls into the below, steel fiber filtering net 136 enters coal bunker 14.
Third part is gone into the stove coal and is advanced coal, preheating, adjusting, cooling
The stove coal process of going into after the dehydration carries the back temperature generally can be down to normal temperature, particularly winter temperature is lower, temperature may be lower, but but wish during coking to go into stove coal temperature remain between 200 ℃ to 300 ℃ more suitable, so need before the coking chamber that enters the pyrolysis of coal stove, carry out preheating to going into the stove coal.
First segment is gone into the stove coal and is advanced coal
As shown in Figure 5: advance that device for coal 2 mainly includes stove cuttings conveyer 21, goes into stove coal bunker 22, the coal dust branch to device 25, coal dust distribution chamber 26, go into stove coal bunker tremie pipe 29, coal dust strainer 23.
