Abstract
A gas carrying, dust removal and gas discharge device of coal moisture control technique belongs to production equipment in coking industry and comprises spiral conveyers and a dust remover. The spiral conveyer is disposed under the dust remover, nitrogen is disposed inside the dust remover, a weighing hopper is arranged under the spiral conveyer, a discharge opening of the weighing hopper is provided with an electric cinder valve, a spiral conveyer is arranged under the weighing hopper, and a belt conveyer is mounted at an output opening of the spiral conveyer. The device is characterized in that a pipeline is arranged on the weighing hopper, and a heat exchanger is disposed on the pipeline. Temperature of the nitrogen after heat exchanging through the steam heat exchanger can be increased to 90 DEG C, and the nitrogen inside the weighing hopper is capable of blocking steam from the spiral conveyers used for ash discharge, thereby preventing dust in the weighing hopper and the dust remover from damping and avoiding blockage of the discharge opening.
Description
Technical field:
The utility model belongs to the coking industry production unit, is specifically related to coal humidifying technology carrier gas dedusting ash exhauster.
Background technology:
In the coal humidifying technology, the carrier gas fly-ash separator filters the coal powder collection that gets off and carries the quality that solves, and directly has influence on the normal operation of coal humidifying technology.Coal damping carrier gas dedusting and other dedusting difference are that its gas contains a large amount of saturated vapors, this is determined by coal humidifying technology characteristics, the coal humidifying technology be exactly will with moisture about 10.5% go into the stove coal, reduce to moisture about 7% coal through the steam rotary dryer, transport to coke oven coal tower then, the coking by coke oven of packing into.Existing coal humidifying technology carrier gas dedusting ash exhauster, the place is often stopped up at ash output hole, and production can't be continued.
Summary of the invention:
The utility model aims to provide the coal humidifying technology carrier gas dedusting ash exhauster that prevents that ash output hole from stopping up.
The realization the technical solution of the utility model is: comprise worm conveyor, fly-ash separator, fly-ash separator has worm conveyor, be connected with nitrogen in the fly-ash separator, worm conveyor has the hopper of weighing, the discharge port of hopper of weighing is provided with electronic unloading valve, is provided with worm conveyor below the hopper of weighing, and the delivery port of worm conveyor is provided with rotary conveyor, the hopper that it is characterized in that weighing is provided with pipeline, and pipeline is provided with interchanger.
Nitrogen in the utility model is by after the vapor heat exchanger heat exchange, the temperature of nitrogen can be brought up to 90 ℃, be passed into the steam in the worm conveyor that nitrogen in the hopper of weighing can stop self-unloading ash usefulness, thereby the dust in avoid weighing hopper and the fly-ash separator makes moist, and just can avoid the discharge port latch up phenomenon to take place.
Description of drawings:
Fig. 1 is the structure iron (rotary conveyor does not show) of the utility model embodiment.
Among the figure, 1. fly-ash separator; 2. worm conveyor; 3. the hopper of weighing; 4. unloading valve; 5. electric motor; 6. worm conveyor; 7. interchanger; 8. nitrogen pipeline; 9. valve; 10. valve; 11. steam-pipe; 12. pipeline.
Embodiment:
Shown in Figure 1, present embodiment comprises worm conveyor 2,6, fly-ash separator 1, fly-ash separator 1 has worm conveyor 2, be connected with nitrogen in the fly-ash separator 1, worm conveyor 2 has the hopper 3 of weighing, the discharge port of hopper 3 of weighing is provided with unloading valve 4, unloading valve 4 drives by electric motor 5, weigh hopper 3 below be provided with the worm conveyor 6 that unloads grey usefulness, the delivery port of worm conveyor 6 is provided with rotary conveyor, the hopper 3 of weighing is provided with pipeline 12, and an end of pipeline 12 is connected with the top of the hopper 3 of weighing, and the other end is connected the discharge port place of the hopper 3 of weighing, pipeline 12 is provided with two valves, be provided with interchanger 7 between two valves, the input aperture of interchanger 7 is connected with nitrogen and steam, and the delivery port of interchanger 7 is installed between two valves of pipeline 12.
Present embodiment be on the existing coal humidifying technology carrier gas dedusting ash exhauster of Shanxi Taigang Stainless Steel Co., Ltd coke-oven plant, carry out improved, promptly weld a segment pipe on the hopper of weighing in existing coal humidifying technology carrier gas dedusting ash exhauster, pipeline is provided with two valves, mounting heat exchanger between two valves (by the ZL type vapor heat exchanger of the Shenyang U.S. heat-exchange equipment of prosperous friend company limited production).
