Description

The energy-saving coal stove of reverse burning type Environment-friendly

The utility model relates to a kind of moulded coal stove, particularly relates to the energy-saving coal stove of a kind of reverse burning type Environment-friendly.

At present, China's town and country civil cooking stove is divided into two classes substantially, first household honeycomb coal stove, and it two is brick kitchen ranges such as food and drink, dining room and brewery, boiler for domestic.Though the former is through improvement, but still many deficiencies, the latter is then based on scatter fire of raw coal, and heat effect thing is low, seriously polluted.Chinese patent 86108484.5 provides a kind of " being provided with the honeycomb briquet stove of steam superheating device ", it comprises flue, steam superheating device, furnace panel, iron chassis, slag wringing device, air-supply arrangement, the chimney that has the heat-exchange dedusting device and the flue blow-off pipe etc. that partly constitute by two, operation principle is, from the flue moulded coal that adds suitable for reading, moulded coal after the burning is discharged from the grey thorax of flue bottom by slag wringing device, and slag wringing device also plays the fire bars effect.Superheated steam by the output of superheated steam device is respectively applied for steaming, boils, washes open water, sends into chimney smoke abatement and dust control, sends into burner hearth bottom and mixes with air.Because this moulded coal is to burn from top to bottom, newly add the maximum stylish moulded coal of moulded coal flue gas and wait to burn and scintillation, steam reduces in a large number; Bottom strand slag can make a large amount of ashes enter flue with steam, is unfavorable for the abundant burning of moulded coal.

It is a kind of from the lower furnace portion coal that the purpose of this utility model is to provide, the energy-saving coal stove of the reverse burning type Environment-friendly that the thermal efficiency is high.

The energy-saving coal stove of the utility model reverse burning type Environment-friendly is to realize like this; it comprises the body of heater that is provided with upper and lower fire door; be connected with the chimney of chimney sewage pipe; the burner hearth that constitutes by top fire box, center ovens tube and bottom wind groove; be arranged on the steam ring of stove tube upper end; be positioned at the fire holding cycle on the steam ring; be arranged on the holder coal sheet control loop of stove tube bottom; be installed in the holder device for coal in the wind groove; be positioned on the chimney and the ring-like water tank that communicates with steam ring inlet, and the chimney steam pipe, furnace bottom steam pipe and the steam output pipe that are connected with the outlet of steam ring.Wherein body of heater generally is made of metal shell and refractory masses, is convenient to transportation, moves, installs.The steam ring except that with the chimney steam pipe with the furnace bottom steam pipe is connected, also be connected with steam output pipe, be convenient to utilize vapour cooking, sterilization or preparation distilled water etc.

Smoke elimination desulfurization sheet can be installed on the chimney steam pipe of the energy-saving coal stove of the utility model reverse burning type Environment-friendly, make flue gas circuitous flowing in chimney, make full use of the fume afterheat heating water tank on the one hand, flue dust in the aspect flue gas can attach on smoke elimination desulfurization sheet in addition, behind the vapor absorption flue dust and drip washing smoke elimination desulfurization sheet of the ejection of chimney steam pipe, the purpose that reduces smoke pollution is discharged, reached to the chimney sewage pipe that connects from the chimney lower end.

Holder coal sheet control loop in the energy-saving coal stove of the utility model reverse burning type Environment-friendly is by the soleplate that is installed in the stove tube bottom, be arranged on the soleplate, be positioned at the fixing ring on the soleplate lower surface, the rotation outer shroud of band handgrip, and be rotationally connected with interior ring respectively, the holder coal sheet of fixedlying connected with outer shroud is formed.When rotating connector will ask the coal sheet to be connected on the fixing interior ring, ring was connected on the soleplate in will fixing again.This holder coal sheet control loop plays grate.Its course of work is, promote handgrip, outer shroud rotates thereupon, drive the holder coal sheet half-twist on it, new moulded coal can be sent in the stove tube from the fixing interior central authorities that encircle, reverse pulling handgrip after reaching the precalculated position, and outer shroud is backward rotation thereupon, the holder coal sheet reverse rotation that drives on it resets for 90 °, and new moulded coal is held.

Holder device for coal in the energy-saving coal stove of the utility model reverse burning type Environment-friendly is made up of holder coal lever bracket and mounted thereto and liftable coal-supporting disk.Its course of work is, operation holder coal lever bracket, and coal-supporting disk raises, and the new moulded coal that holds is thereon sent in the stove tube.

The operation principle of the energy-saving coal stove of the utility model reverse burning type Environment-friendly is, newly adding moulded coal places on the coal-supporting disk, operation holder coal sheet control loop, moulded coal in the stove tube is dropped on the new moulded coal, restart holder coal lever bracket, coal-supporting disk is risen moulded coal is sent in the stove tube, and operation holder coal sheet control loop, holder coal sheet is held coal burn.Moulded coal after the burning is ejected from stove tube upper end by new moulded coal, is taken out by upper furnace door.Heated water enters the steam ring in the annular water tank, and the steam of generation by the ejection of chimney steam pipe, absorbs flue dust respectively; By the ejection of furnace bottom steam pipe, the fugitive constituent and the free carbon that newly add in the moulded coal are mixed with steam and air, form class water-gas and enter fully burning in the stove tube, both eliminated black smoke, strengthened firepower again; Supply with boiling, sterilization or preparation distilled water etc. by the steam of steam output pipe output.

The advantage of the energy-saving coal stove of the utility model reverse burning type Environment-friendly is from the bottom coal, changes behind the coal not scintillation, and firepower is prosperous, the steam foot.Furnace bottom sprays into steam, smoke abatement and dust control in the stove combustion process.Spraying steam in the chimney, further smoke abatement and dust control reduces dust polluting environment.Ring-like water tank makes full use of fume afterheat, except that supplying with steam ring hot water, also can directly utilize.Upper furnace door also plays the secondary air effect except that the deslagging effect, more help abundant burning.But this moulded coal stove modular in design processing and fabricating is carried out standardized production in batches.
