As a preferred solution, heat exchanger 38 is provided on the circulating water pipe 39 of circulated water-used dust collector 3.Due to from
The water flowed out in sedimentation basin 36 is warm water (even hot water), so after heat exchanger 38 is set on circulating water pipe 39, it can be with
It realizes the heating to greenhouse, substantially increases the thermal efficiency, save the energy.
Of the invention is as follows with the working principle of the matching used dual dust pelletizing system of coal-fired hot-blast stove:
High-temperature gas in coal-fired hot-blast stove 1 is entered in cyclone dust collectors 2 by pipe 10, and high-temperature gas is being oriented to
It is rotated down under the action of plate 22, the dust of bulky grain can drop to the bottom of outer tube 20, short grained ash due to gravity and collision
Dirt then can enter by inner tube 21, flue 24 and carry out final dusting in circulated water-used dust collector 3, and circulated water-used dust collector 3 sinks
Water in shallow lake pond 36 is sent into dirt pocket 30 under the action of water circulating pump 37 via circulating water pipe 39, and recirculated water is via dirt pocket
30 flow into downpipe 35, then flow into sedimentation basin 36, during circulating water flow is through dirt pocket 30, from smoke inlet stream
The recirculated water entered in flue dust and landing in dirt pocket 30 collides in dirt pocket 30, and the soot dust granule in flue dust is dissolved in recirculated water
In, soot dust granule flows into sedimentation basin 36 with recirculated water via downpipe 35, and clean air is then by air-introduced machine 33 from cigarette
Gas outlet is drawn, and is discharged by a pipe 34；Circulated water-used dust collector 3 is in dust removal process, recirculated water and high-temperature flue gas
Contact, produces warm water, a heat exchanger 38 is arranged on circulating water pipe 39, can increase greenhouse temperature, improves the thermal efficiency, section
Saving the energy (certainly, if conditions permit, can also access the warm water in irrigation system, be irrigated by irrigation system
Crop improves the speed of growth and yield of crop).
Since cyclone dust collectors 2 and circulated water-used dust collector 3 are applied in combination for we, dual dedusting, so good purification,
The concentration of the flue dust of coal-fired hot-blast stove generation can be greatly reduced.
It should be noted that the above embodiments do not limit the invention in any form, it is all to use equivalent replacement or equivalent change
The mode changed technical solution obtained, falls within the scope of protection of the present invention.
