Abstract
An energy-saving environment-friendly horizontal boiler with two-way air (oxygen) supply belongs to the technical field of boilers. An air ejector (3) with multi-line crossing diamond meshed holes is arranged above a grate and enables rising black flue gas generated by superfine pulverized coal and asphalt in a hearth to completely burn in the hearth, the utilization rate of heat in the coal and the heat efficiency of the boiler are increased, and environmental pollution caused by the black flue gas generated by the superfine pulverized coal and the asphalt is eliminated.
Description
Affiliated technical field: the present invention relates to a kind of horizontal boiler, belong to the boiler technology field.
Background technology: in all parts of the country according to investigations, the horizontal boiler of the bituminous coal of all size of manufacturing and use is because of designing the following defective of unreasonable generation; Coal is at individual event (from fire grate bottom) air supply, coal combustion process produce five sections (1, the fresh fuel district.2, separate out the volatilization subregion.3,3a epoxidation zone.4,3b reducing zone.5, burning-out zone), when coal combustion arrived the reducing zone, oxygen exhausted, and reaction and defective below this section produces: 1. carbon dioxide reaction generates carbon monoxide.2. do not have the black gas that oxygen supply pitch produces, the former is burnt,, waste energy and contaminated environment to external world's discharging black smoke.
Summary of the invention: in order to overcome the defective of the horizontal boiler existence of falling existing all size; The present invention provides a kind of new design: by horizontal boiler fire grate top, set up multirow intersection diamond-mesh eyelet injection air device (3), the former can be with the superfine pulverized coal that rises; Black gas and dust that pitch produces; The pressure drop of blocking is to flame top, the black gas that impels superfine pulverized coal and pitch to produce, completing combustion in burner hearth.
Improve heat energy utilization rate and raising boiler thermal output in the coal on the one hand, eliminate the black gaseous contamination environment that superfine pulverized coal and pitch produce on the other hand.
Accompanying drawing and symbol description: (Fig. 2 is the netted eyelet injection air of a multirow intersection diamond pattern device sketch map).
Fig. 1 promptly is the whole bearing of boiler, is again the functional part support of following symbol.
1, adds coal bunker.2, coal gate.3, multirow intersection diamond-mesh eyelet injection sky is penetrated the air device.4, titanium steel removes the dust rotor plate.5, sprocket wheel.6, fire grate.7, advance air bin.8, water inlet pipe.9, outer tube.10, inner tube.11, outlet pipe.12, incoming air conduit.13, Φ 6 outgoing air conduit eyelets.14, Φ 8 outgoing air conduit eyelets.15, the 30 ° of angle eyelets that are tilted to the left, 16,30 ° of angle eyelets are tilted to the right.
The technical application scheme: the present invention by following three flow processs (1, flue gas stream device.2, air flow process.3, current journey) realize.
One, flue gas flow: square opening is connected with coal gate (2) import coal under the coal bunker (1) from adding, and coal gate (2) outlet is connected with fire grate (6) top, and fire grate (6) top and multirow intersect below the diamond-mesh eyelet injection air device (3) between the two that the slit is connected.
Two, air flow process: air regulator outlet in blower export place is connected with incoming air conduit (12) right side mouth; Incoming air conduit (12) left side respectively with each inner tube (10) intracavity inter-connection; Inner tube (10) inner chamber goes out air scoop and 13,14,15 and 16 each air intake opening eye are connected, and 13,14,15 and 16 respectively go out the airport eye is connected with coal combustion position, fire grate top.
Three, current journey: water is connected with water inlet pipe (8) left and right sides water inlet pipe mouth by boiler bottom both sides collection case delivery port, and the slit is connected between water inlet pipe (8) both sides effluent pipe mouth and outer tube (9) inwall and inner tube (10) outer wall.
Explanation of nouns and function
1, multirow intersection diamond-mesh eyelet injection air device (3).1. multirow be meant in the horizontal boiler burner hearth long with wide different, in establish also difference of how many root blast air pipes.As not only long but also wide in the large-size horizontal boiler furnace, it is not only much but also longer to establish blast air pipe.2. intersect and be meant the blast air pipe of establishing, whenever be separated by 100 millimeters and establish the 30 ° of angles (16) that are tilted to the right, the 30 ° of angles (15) that are tilted to the left.More than the two air that ejects become X-shape, and diamondwise and netted (16).Function: reach the superfine pulverized coal of blocking and rising, black smoke gas and dust that pitch produces.Impel both completing combustion, the latter falls in the burner hearth.Improve heat energy utilization rate and raising boiler thermal output in the coal on the one hand.Pollution abatement environment purpose on the other hand.
2, titanium steel removes dust rotor plate (4).Because of establishing multirow intersection diamond-mesh eyelet injection air device (3) in the fire grate top,, behind the dust that falls above the loam cake titanium steel plate, flow to titanium steel and remove dust rotor plate top because of the former is provided with the gradient.Function: often rotate titanium steel and remove the dust rotor plate, dust is removed.
