The utility model not only can supply hot blast, but also hot water simultaneously. The heat exchange is sufficiently carried out among the high temperature fume, the air in the jacket passage, the air in the tube of the column tube bundle in the smoke and fire box, and the water in the tube of the water tube assembly of the furnace chamber. The horizontal coal hot blast furnace having high thermal efficiency avoids the burning loss of the column tube bundle from the high temperature smoke and fire and prolongs the service life of the equipment.
Description
The utility model relates to a kind of horizontal coal-fired hot-blast stove.
Known coal-fired hot-blast stove can only be exported hot blast, function singleness.
The purpose of this utility model provides the multipurpose horizontal coal-fired hot-blast stove of a kind of hot wind supply simultaneously and hot water.
The purpose of this utility model is achieved in that the water pipe group is installed at the rear portion in the burner hearth of horizontal coal-fired hot-blast stove, water in the water pipe group water pipe absorbs the heat of pyrotechnics in the burner hearth, reduce the temperature that enters pyrotechnics case flue gas, avoided the scaling loss of tubulation bundle in the pyrotechnics case effectively; In order to make the air and the pyrotechnics that enter in the boiler fully carry out heat exchange, be provided with the chuck air duct in front and back, the both sides of burner hearth, thus the utility model simultaneously hot wind supply and hot water, and the thermal efficiency is higher.
The utility model is taked following structure: it comprises boiler casing, boiler inner wall, shell and tube pyrotechnics case, exhaust opening, burner hearth, horizontal reciprocating furnace grate, air inlet, air outlet, chuck air duct, water pipe group, upper water box, lower header.The tubulation bundle of horizontally-arranged installation is arranged in the shell and tube pyrotechnics case, and the two ends of tubulation bundle are fixed with tube sheet, in shell and tube pyrotechnics case deflection plate are installed uprightly, and shell and tube pyrotechnics case forward and backward respectively has an air collecting box, and the base plate of shell and tube pyrotechnics case promptly becomes the burner hearth top cover; The water pipe group is installed in the rear portion in the burner hearth, and the water pipe of water pipe group is uprightly installed, and the top of water pipe group has upper water box, bottom that lower header is arranged, and the water pipe of water pipe group is communicated with upper water box and lower header and is fixed as one, and upper water box has outlet pipe, and lower header has water inlet pipe; The chuck air duct by burner hearth after before the burner hearth side chuck, burner hearth of chuck, burner hearth both sides chuck form, above-mentioned three kinds of chucks communicate successively, air inlet communicates with chuck behind the burner hearth, chuck communicates with preceding air collecting box before the burner hearth.The pyrotechnics that coal combustion produces in the burner hearth is with the chuck of burner hearth front and back, both sides, the shell and tube pyrotechnics case heating of roof of the furnace.Pyrotechnics space outside the water pipe of water pipe group enters the burner hearth afterbody, rises to the space outside the tubulation bundle of shell and tube pyrotechnics case after the combustion, because the effect of deflection plate, upper and lowerly comes and goes some backhauls and discharges from exhaust opening.Air is imported air inlet by air blast, and it is divided into two parts; A part by chuck, preceding air collecting box before chuck, burner hearth side chuck, the burner hearth behind the burner hearth, enters in the tubulation of shell and tube pyrotechnics case successively, fully carries out heat exchange with high temperature pyrotechnics, by air outlet output, uses for the user; Another part air enters air compartment by the air channel by the air compartment import and uses for burning.Water enters lower header by water inlet pipe, fires in the water pipe of laggard oral siphon group, absorbs the heat of pyrotechnics in the burner hearth, enters upper water box again and is exported by outlet pipe, for heating, slurry, reaches the purpose of while hot wind supply and hot water.
Because the utility model is taked said structure, the water pipe group is positioned in the horizontal coal-fired hot-blast stove burner hearth and before and after burner hearth, there is the chuck air duct both sides, the utility model is hot wind supply and hot water simultaneously, enlarge the function of coal-fired hot-blast stove, thermal efficiency height, and, avoided the scaling loss of tubulation owing to reduced the temperature that enters flue gas in the shell and tube pyrotechnics case.
Detailed structure of the present utility model is provided by embodiment and accompanying drawing thereof.
