Description
Technical field
The utility model belongs to field of boilers, is specifically related to a kind of cultivation boiler dedicated.
Background technology
Nowadays in aquaculture, no matter be aquaculture or livestock-raising, usually all adopt boiler to improve the temperature of breeding environment in winter, to reach the breeding technique requirement, impel the healthy Fast Growth of aquaculture organism.All to adopt normal-pressure hot-water boiler to realize in the market, common normal-pressure hot-water boiler is many can not use II, III bituminous coal, smoke pipe stops up serious when using II, III bituminous coal, and easy over-emitting black exhaust, soot emissions exceed standard, the anthracite so burn more, but there is the high prominent question of use coal expense usually in the burning anthracite, and causing has increased aquaculture cost.
Summary of the invention
The purpose of this utility model is, a kind of II that can burn, III class bituminous coal are provided, and the cultivation that soot emissions are up to standard, the thermal efficiency is high, operating cost is low is boiler dedicated.
In order to realize the utility model, the boiler dedicated technical scheme of taking of the utility model cultivation is as follows:
A kind of cultivation is boiler dedicated, and it comprises burner hearth, chimney arch, coal feeding hole, loose cinder notch, gray-drawing port, overfire air device, horizontal smoke pipe, perpendicular smoke pipe, chimney arch cleaning door, cleaning door; Wherein, offer coal feeding hole, loose cinder notch and gray-drawing port on the burner hearth front console, loose cinder notch be located at coal feeding hole below, offer gray-drawing port below loose cinder notch; The burner hearth rear end arranges chimney arch; Establish the first heat transfer zone above burner hearth, the second heat transfer zone is established in the burner hearth back; The right flank lower end of burner hearth arranges overfire air device; The first heat transfer zone is provided with the horizontal smoke pipe of some rows, is provided with the chimney arch cleaning door below horizontal smoke pipe and is used for removing dust stratification on chimney arch; The second heat transfer zone is provided with the perpendicular smoke pipe of some rows, is provided with cleaning door below perpendicular smoke pipe, and cleaning door and perpendicular smoke pipe communicate.
Be provided with above the second heat transfer zone described above upper smoke box, below be provided with lower smoke box, perpendicular smoke pipe is welded between upper smoke box and lower smoke box.
Cleaning door described above be arranged in the lower smoke box of the second heat transfer zone and and lower smoke box communicate.
The base of burner hearth described above and the second heat transfer zone is provided with pulley.
Overfire air device described above is provided with aid distributing pipe, and this aid distributing pipe outlet is located in the chimney arch mouth.
The utility model cultivation is boiler dedicated is to realize like this burning:
II, III class bituminous coal are closed coal feeding hole, loose cinder notch, gray-drawing port after in coal feeding hole joins the stove burner hearth, wind enters the fire grate of burner hearth from wind inlet, the coal seam normal combustion, the chimney arch that the top of the rear fire grate of burner hearth arranges, " black smoke " that produces in combustion process (carbon black particle and unburned fugitive constituent) from chimney arch outlet by the time, be forced to return high temperature combustion zone on fire grate by reignition.In the situation that the overfire air device air-supply, the coal gas of generation is fully burning under the state of oxygen enrichment, and clean flame enters the horizontal smoke pipe of the first heat transfer zone along the chimney arch rear channels.High temperature pyrotechnics in the horizontal smoke pipe of the first heat transfer zone with smoke pipe outside water carry out heat exchange, enter the second heat transfer zone after heat exchange, then enter successively perpendicular smoke pipe, the direction of its circulation is that the first perpendicular smoke pipe is from top to bottom in some perpendicular smoke pipes, the second perpendicular smoke pipe is for from bottom to top, simultaneously carry out heat exchange with water in the process of circulation, the dust in flue gas falls into and erects the cleaning door that smoke pipe is communicated with and enter lower smoke box at effect of inertia.
The dust that produces on chimney arch can be cleared up by the chimney arch cleaning door; In the situation that air-introduced machine work produces negative pressure, the air door that can automatically open once with overfire air device enters in burner hearth air automatically, and whole process does not need manually-operated.The carbon black ion that II, III class bituminous coal produce in combustion process under the secondary excess oxygen simultaneously continues fully burning, has not only reached the purpose that eliminates smoke, and has also improved simultaneously the thermal efficiency of boiler.
The boiler dedicated good effect of the utility model cultivation is:
By chimney arch and coordinating of Secondary Air reaching the smoke elimination purpose; By the inertial dust collection during break-in in the smoke three-pass process of circulation; Can fully guarantee boiler chimney over-emitting black exhaust not when burning II, the III class bituminous coal by two large effects, save operating cost, and improved the thermal efficiency.Thereby the switch of controlling air-introduced machine by the temperature of plant is opened or burn-out automatically, reaches the combustion process Automatic Control, can save artificial.
The utility model applicant did effectively checking, and when using II or III bituminous coal, flue gas is without black smoke, and dust emission is less than 70mg/Nm
3, can substitute the burning anthracite fully, fume emission satisfies the environment protection emission requirement fully.
