Description

The efficient minute-pressure steam boiler of shell and tube

Technical field the utility model relates to a kind of steam boiler, is a kind of minute-pressure steam boiler specifically.

The present boiler of background technology mainly contains two kinds, and a kind of is the steam bearing boiler; A kind of is stress-free warm homogeneous solution-type reactor, and does not need boiler that steam has big pressure also seldom between the heat that only needs steam, and what have individually also is the improved steam oven of water-heating stove, and shortcoming is that body of heater is big, and efficient is low.In fact, the aspect such as producing and civilian, this needs steam heat and does not need steam to have the boiler of big pressure that the very big market demand is arranged.

The summary of the invention the purpose of this utility model is to provide a kind of shell and tube efficient minute-pressure steam boiler, and it is not provide steam-heated device for some do not need the facility of big steam pressure.

The technical solution of the utility model is as follows:

This apparatus main body is a cylinder, and the bottom is a burner hearth in the cylinder, and the middle part is the equally distributed tubulation that is communicated with burner hearth, and top is steam chest; Above-mentioned tubulation is connected between the upper perforated plate and lower perforated plate of tubulation frame, and burner hearth is inserted through lower perforated plate in the lower end of tubulation, and the upper end of tubulation is connected with the interior smoke-box of upper of furnace body through upper perforated plate, the last termination flue of this chamber; Be the space that water is arranged outside the burner hearth upper tube array and between the furnace tube; Smoke-box be above-mentioned steam chest outward in the upper of furnace body, and steam chest is the outlet of termination steam guiding tube on body of heater, taps into the mouth of a river at the lower position of body of heater, and this mouth is repeatedly kicked into water pipe, and the water inlet pipe middle part connects a pressure filling pipe in addition, so that moisturizing when moving, water inlet also connects blow-off pipe; A water level meter is adorned on cylinder top, connects an observation panel on the water level meter one wing furnace thorax.

Be jacket structured between above-mentioned cylinder and the burner hearth.

Tap into hyponome with the steam chest isometry position on the above-mentioned water inlet pipe.

Advantage of the present utility model is: 1, owing to adopt the shell and tube heat exchange, heating surface area is big, and heat loss is little, and evaporation rate is fast, so efficient energy-saving.2, another purposes of this stove is that water is changed into conduction oil, is connected with baking box then, forms to have the heat energy utilization equipment that constant temperature is economized on coal, and can be used for food processing.

Description of drawings Fig. 1 is the utility model cross-sectional view.

The utility model is described in further detail below in conjunction with accompanying drawing for the specific embodiment.

Can see that by Fig. 1 this apparatus main body is the cylinder of making of steel plate 7, it is outer be heat preservation rock layer 6, be jacket structured 2 between cylinder bottom and the burner hearth 1, so that the interior heat of absorption burner hearth; The many tubulations 5 that are communicated with burner hearth at middle part evenly distribute, the tubulation number can be according to the boiler design of different size, tubulation is connected between upper perforated plate 9 and the lower perforated plate 4, the lower end of tubulation is welded on the burner hearth chuck inner core through lower perforated plate, the upper end of tubulation is welded on interior smoke-box 11 lower ends of upper of furnace body, the last termination flue 13 of this chamber through upper perforated plate; Cock off in the tubulation, between the outer and furnace tube of burner hearth upper tube array for the hydrospace is arranged; Smoke-box is outward a steam chest 10 in the upper of furnace body, and steam chest is termination steam guiding tube outlet 14 on body of heater; Establish water inlet 19 in chuck position, the bottom of body of heater, this mouth taps into water pipe 16, taps into hyponome 15 with the steam chest isometry position on the water inlet pipe, and water inlet pipe 16 valves 20 are divided into the position and compressed into waterpipe jointing 17, so that uninterrupted moisturizing when the steam operation is arranged; Upperly in the cylindrical shell install a water level meter 8 so that observe water level, peak level should not surpass upper perforated plate, and lowest water level should not be lower than water level meter lower end, and the attention amount of makeup water is in operation; Above-mentioned water inlet connects the blow-off pipe 18 of scale removal, so that prepurging snaking after the long operational time fouling; The 3rd, fire door, the 12nd, safety valve; 108 pipes 21 of the flanged and blind plate of water level meter one wing furnace thorax upper end welding one are so that observe fouling and prepurging scale removal situation is used in the future.

Cock off in this device tubulation, tubulation is outward a water, the outer water of tubulation is heated and is evaporated to steam and directly enters steam chest, the steam of steam chest directly enters with the heat place by the steam transmitting pipe road, it all is uncovered using the facility of heat, is not closed container, and can absorbs heat energy in a large number, so whole system has just been carried heat energy by steam, and does not have the bigger steam pressure of closed interruption-forming.
