Description

A kind of steam, boiling water boiler for dual purpose

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

At present, general little brewery is used to steam wine and provides drinking water to the worker, the boiler of usefulness vapour, water such as have a bath mainly comprises upper and lower water cavity, be located at down and be with the burner hearth (also claiming flue) of grate and fire door in the water cavity and be located at the burner hearth internal upper part and the L type water screen tube of annular setting, the flue that between upper and lower water cavity, also is provided with an annular high-temperature flue gas chamber and this smoke chamber is communicated with burner hearth, and the chimney that is connected with the ring smoke chamber, the housing of whole boiler then is made up of the base plate of upper and lower water cavity shell and high-temperature flue gas chamber." wine brewing boiler " that " east, Zi Gong gas apparatus company " produces promptly belongs to this type of boiler.Though this boiler has overcome the big disadvantage of general direct-fired civil boiler smoke discharge amount, has also improved the thermal efficiency to a certain extent.But because the annular high-temperature flue gas chamber of this boiler 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, and the while is offered ash output opening on this ring flat-plate; 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.Carry out heat exchange, both influenced boiler thermal output, make the chimney emission temperature too high because the annular high-temperature flue gas chamber of this boiler only has three faces to contact with water; Yin Gaowen and make high-temperature flue gas chamber annular bottom plate easy burn-out again as the boiler shell some; The existence of inner lead (slough) has not only reduced the heat exchanger effectiveness in this district, and, the water in this district becomes easy fouling district because of can not freely circulating, also have influence on the raising of the thermal efficiency, thereby such boiler exists high-temperature flue gas chamber set-up mode and position unreasonable, the Natural Circulation of water is relatively poor between the upper and lower water cavity, easy fouling in slough and easy-clear have not all influenced the further raising of boiler thermal output and the defectives such as life-span of boiler.

It is unreasonable with the high-temperature flue gas chamber set-up mode and the position that overcome background technology and exist that the purpose of this utility model provides a kind of steam, boiling water boiler for dual purpose, and the Natural Circulation of water is relatively poor between the upper and lower water cavity, easy fouling in slough and disadvantage such as easy-clear not; Reach and enlarge high-temperature flue gas chamber heat exchange area, the thermal efficiency and the gas production of raising boiler, the purposes such as service life that prolong high-temperature flue gas chamber and boiler shell.

Solution of the present utility model is: on basis of background technology annular high-temperature flue gas chamber changed and be located in the upper water cavity body, be connected with the upper water cavity housing with gusset and realize deashing by hand hole or hand hole; Upper and lower water cavity shell then directly links into an integrated entity and forms boiler shell, make simultaneously water in the upper and lower water cavity by annular high-temperature flue gas chamber the Nei Huan district and the outer ring surface by annular high-temperature flue gas chamber and passage between bottom and the upper water cavity inwall and following water cavity between two of formation follow passage naturally, both eliminated the slough, overcome the problem of easy fouling again, thereby realized its purpose.Therefore, the utility model comprises upper and lower water cavity, be located at down and be with the burner hearth of grate and fire door in the water cavity and be located at the burner hearth internal upper part and the double L water screen tube of annular setting, annular high-temperature flue gas chamber and the flue that this smoke chamber is communicated with burner hearth, the chimney that is connected with the high-temperature flue gas chamber and be located at manhole, steam (vapor) outlet on the upper water cavity housing, the boiling water outlet; Key is that annular high-temperature flue gas chamber is located in the upper water cavity, and its outer ring surface is provided with 1～4 hand hole; Annular high-temperature flue gas chamber is fastenedly connected with the upper water cavity housing by hand hole or hand hole stiffened panel, and upper and lower water cavity then directly welds and strikes up partnership and constitute the housing of boiler.The described chimney that is connected with the high-temperature flue gas chamber both can be located at the upper water cavity outside and be connected with the outer ring surface of annular high-temperature flue gas chamber, also can be located at upper water cavity body top and pass this water cavity to be connected with the inner ring surface of high-temperature flue gas chamber.

The utility model is owing to be located at annular high-temperature flue gas chamber in the upper water cavity body, and integral body all is dipped in and carries out heat exchange in the water with it during work, thereby has improved effectively the efficient of heat exchange and the life-span of high-temperature flue gas chamber; In addition, after annular high-temperature flue gas chamber is located in the upper water cavity body, make and form a water stream channel between the outer ring surface of upper water cavity body shell and smoke chamber and the annular bottom plate, directly be communicated with following water cavity, thereby both eliminated the easy fouling of stagnant water district, make again to form inside and outside two circulation canals when working between the upper and lower water cavity, this improves the efficient of heat exchange again to a certain extent; Whole boiler compared with background technology and can be improved steam production about 10%.After the base plate of annular high-temperature flue gas chamber was not re-used as the part of boiler shell, just there was not special high-temperature region in boiler shell, from and service life of having improved whole boiler effectively.Therefore, the utlity model has the high-temperature flue gas chamber and be provided with rationally, enlarged heat exchange area, improved the thermal efficiency and the steam production of boiler effectively, prolonged the characteristics such as service life of high-temperature flue gas chamber and boiler shell.
