Description

A kind of directly burning type vapour, homogeneous solution-type reactor

The utility model belongs to a kind of steam, (heat) water ordinary-pressure boiler for both boils.Be particularly suitable for for brewery provide steam wine with vapour and for daily life domestic water is provided, with vapour etc.

In the patent No. is ZL98229813.7, and denomination of invention is for disclosing a kind of gerotor type boiler that little brewery steams wine and usefulness vapour, water are provided for daily life that can be used as in the patent documentation of " wine brewing power economized boiler ".This boiler comprises furnace shell, upper and lower water cavity is located at down and is with the burner hearth of grate and fire door in the water cavity and is positioned at the L type water screen tube that burner hearth internal upper part annular is provided with, the flue of being located at the annular high-temperature flue gas chamber between the upper and lower water cavity and this smoke chamber being communicated with burner hearth, chimney, hand hole etc.This boiler both as the secondary heat-exchange device, further heats the water in the upper water cavity owing between the upper and lower water cavity of upper furnace the ring smoke chamber is set, again as the sootfall device, though have characteristics such as environmental pollution is less.But because the ring smoke chamber is to be welded in down on the shell on water chamber top, its annular base plate directly contacts with air and becomes a part of boiler shell, upper water cavity housing then seat makes a formation narrower hydrostatic (stagnant water) exchange area hot in nature between the outer ring surface of upper water cavity lower housing portion and high-temperature flue gas chamber on the extended surface of this annular base plate.This kind set-up mode makes annular high-temperature flue gas chamber only have three faces to contact with water to carry out heat exchange, both influenced the thermal efficiency, again can Yin Gaowen and make smoke chamber annular bottom plate easy burn-out as the boiler shell some; The existence in hydrostatic (stagnant water) district, easily fouling, also influence the raising of the thermal efficiency, thereby this type of boiler exists flue gas heat exchange method and Position Design unreasonable, heat exchange area is little, be heated around the boiler inhomogeneous, the thermal efficiency is low, steam moisture is big and temperature is lower, cigarette ash is cleared up than disadvantages such as difficulties.

The purpose of this utility model is the defective that exists at background technology, improve a kind of directly burning type vapour of design, homogeneous solution-type reactor, the flue gas heat exchange method is reasonable to reach a high temperature, and has enlarged heat exchange area effectively, eliminate easy fouling district, improve purposes such as the thermal efficiency and vapor (steam) temperature and deashing convenience.

Solution of the present utility model is to adopt high burner hearth, is about to burner hearth and increases to upper water cavity, and set up a hydroecium combustion chamber (water cavity) in the upper furnace of increasing; The bottom of this combustion chamber and L type water screen tube are connected, and the top was provided with steam pipe along the smoke tube mouth exterior annular, this is crossed the high temperature cigarette district that steam pipe passes roof of the furnace and is communicated with upper water cavity top, simultaneously on hydroecium combustion chamber anchor ring, establish a manhole so that to its maintenance, this manhole is by passing burner hearth communicating pipe and be communicated with water cavity and over against the manhole import of being located on the body of heater shell, thereby realizes its purpose.Therefore, the utility model comprises the body of heater shell, upper and lower water cavity, burner hearth and be located at L type water screen tube in the burner hearth, fire door, grate, base, chimney, water inlet base, heat (boiling) water pipe seat and water level meter base; Key is that the top of L type water screen tube in burner hearth also is provided with the hydroecium combustion chamber of band manhole, and the combustion chamber top was provided with steam pipe along the smoke tube mouth exterior annular, and this is crossed steam pipe and passes roof of the furnace and be communicated with water cavity top; Upper and lower water cavity then is located between furnace enclosure and the body of heater shell; L type water screen tube upper end strikes up partnership with the seal weld of hydroecium combustion chamber, and the hand-hole on the hydroecium combustion chamber is communicating pipe then by being welded on the furnace enclosure and being communicated with upper water cavity and over against the hand-hole of being located on the body of heater shell.In order to make the preheating water that enters in the hydroecium combustion chamber steady, balanced, are set 6～12 communicating pipes that are communicated with water cavity in hydroecium furance stack side bottom.And convenient for deashing, on chimney, be provided with a tube for removing ash seat; On the position between hydroecium combustion chamber top and the roof of the furnace, also be provided with the deashing hand hole at body of heater shell and furnace enclosure.Place, water cavity bottom also is provided with the hand hole of removing contamination and be positioned at down at the body of heater outer casing underpart.

The utility model is owing to increase burner hearth to upper water cavity, and a hydroecium combustion chamber is set up on L type water screen tube top in burner hearth, both enlarged heat exchange area effectively, high-temperature flue gas rises between furnace enclosure and hydroecium combustion chamber, internal and hydroecium combustion chamber carries out heat exchange, external then directly the water in the upper water cavity is heated by furnace enclosure, improved heat exchanger effectiveness again effectively; The high-temperature flue gas that rises between hydroecium combustion chamber and the roof of the furnace heats the steam of crossing steam pipe and upper water cavity top again, from and improved vapor (steam) temperature, steam moisture reduces relatively.Therefore, it is big, reasonable in design to the utlity model has heat exchange area, quick heating, water Natural Circulation smoothness, stable in the thermal efficiency and the vapor (steam) temperature height, stove, characteristics such as deashing, easy maintenance.
