In order to ensure that no dust exists in the closed flow control type transfer system to the greatest extent, the whole transfer system and the front 12m of the lower layer closed conveying system 10 are made into a fully-closed structure, and meanwhile, materials wetted at the scraping plate can be dried through the negative pressure state generated by the closed flow control type transfer system to ensure that dust cannot overflow the closed flow control type transfer system to a transfer workshop.
In order to solve dust generated in the closed flow control type transfer system, a negative pressure type dust removing system is adopted at the 6m position of the lower layer closed type transfer system 10, the whole transfer station is closed, materials fall into the closed flow control type transfer system from the upper layer conveying system 1 to form pressure difference, positive pressure states are formed at the positions of the first flow control funnel 3 to the fourth flow control funnel 9 and the front 6m position of the lower layer closed type transfer system 10, and the negative pressure type dust removing system is adopted at the 6m position because the whole closed flow control type transfer system is in a closed state, the materials reach the lower layer closed type transfer system 10 from the coal dropping pipe 8, and upwards run through a belt to cause induced airflow and traction airflow, so that the dust is diffused and upwards flows through the closed lower layer closed type transfer system 10. An induced draft fan is arranged at the position of the lower-layer closed conveying system 10 with six meters, the induced draft fan is connected with a dust remover, and positive pressure is eliminated under the dual actions of the induced draft fan and the dust remover, so that dust in a transferring room is removed greatly. Meanwhile, the negative pressure type dust removing system is opened while the coal separator is opened, the time difference exists between the opening of the coal separator and the coal falling, and the time difference is utilized to form a negative pressure state at the lower closed type conveying system 10, so that the efficiency of the negative pressure dust remover is greatly improved.
Based on the ansys finite element analysis, the pressure simulation is carried out on the whole closed flow control system, as shown in fig. 7, the upper layer conveying system 1 is taken as an air inlet, the lower layer closed conveying system 10 is taken as an air outlet, when the material is sent from the upper layer conveying system 1 to the closed flow control transfer system by a belt conveyor, the material is 19424pa at the moment, when the material reaches the cylindrical coal dropping pipe 8, the pressure becomes 20939pa, when the material falls into the lower layer closed conveying system 10, the pressure difference generated by upward flowing of the originally stable air is 21848pa due to upward movement of the belt conveyor, and the 9m position of the lower layer closed conveying system 10 is added with a processing air quantity of 7560m 3 /h, filter area 45m 2 The resistance is 1200pa, the wind speed is 1.2m/min, the induced draft fan with full pressure of 2497-2184pa forms a negative pressure field, the air containing dust is sucked into the induced draft fan of the matched dust removing unit through the induced draft fan and then is connected with a dust removing system, when dust-containing gas enters the filter chamber through the air port, the dust is introduced into the filter chamber from outside to inside, the dust is blocked on the outer surface of the filter bag, and clean air enters the filter bag and is discharged into the atmosphere from the air outlet through the ejector and the clean air chamber. When the running time of the dust remover reaches the set ash removing and discharging time, compressed gas in the gas storage tank is sprayed out through the output pipe, tangentially enters the annular channel of the ejector through the plug-in pipe, and is sprayed downwards from the annular channel at the speed of sound, certain vacuum is formed at the upper part of the ejector, part of air in the clean air chamber is induced into secondary air flow, and the compressed air and the secondary air flow enter the filter bag to enable the filter bag to rapidly expand, so that impact vibration is caused, external air flow is formed, dust adhered outside the filter bag and among fibers is blown down, and the filter bag is cleaned.
The cleaned dust falls to the dust discharge port and is discharged by the dust discharge valve, and after the blowing is finished, the filter bag is in a filtering state.
The wet spray dust removal system is installed at the tail end of the lower closed conveying system 10, and after the system is started, the system is continuously sprayed for secondary dust removal, so that the dust overflow amount is controlled to be minimum when materials leave a fully closed structure with the length of 12 m.
In order to realize maximum dust removal, 6-8 wet spray dust removal systems are arranged above the remaining open type belt conveyors, a small amount of dust can spread among rollers, 6-10 wet spray dust removal systems are arranged at the rollers of the whole belt conveyor, the wet spray dust removal systems at the rollers not only remove dust, dust-falling liquid sprayed out of the belt conveyors can fall at the bottom of a coal conveying stack bridge due to gravity, and the dust can possibly remain at the bottom of the coal conveying stack bridge, so that the wet spray dust removal systems at the rollers also play a role of flushing dust remained at the bottom of the coal conveying stack bridge, so that dust-falling liquid containing dust can be better collected, and secondary utilization of coal dust can be carried out.
The utility model can obviously improve the dust removal rate by adopting the five transfer stations and six coal conveying systems, and can meet the fire safety index while controlling the dust concentration index, so that the coal conveying systems of the power plant are safer and more efficient in operation.
