Description

The anti-stove that burns of vertical pipe type

The utility model is the anti-stove that burns of a kind of vertical pipe type, and steam, boiling water and warm water can be provided, and is required to satisfy daily life.

Existing anti-burning stove is a rectangular flue because it adopts, thereby brings problems such as, be heated weak effect little such as heating surface area, heat skewness; Secondly, adopt cylinder because of the combustion chamber, gas approach is a plain base, so hot flue gas rising resistance is big, radiation effect is poor.

Task of the present utility model be to provide that a kind of heating surface area is big, effective, the uniform heat distribution of being heated, the anti-stove that burns of hot flue gas rising resistance vertical pipe type little, that radiation effect is good.

Task of the present utility model is finished like this, the anti-stove that burns of a kind of vertical pipe type, by preheating water tank 26 and the boiled water tank 27 separated by dust chamber 24, cigarette thorax 28, two ends that are positioned at preheating water tank 26 push up the hot beam tube flue 25 in top that is connected with smoke chamber 28 with dust chamber Room 24 respectively, combustion chamber 14, raw coal flue gas process chamber 19, two ends that are located at second-time burning fire grate 13 and the water pipe furnace grate 29 on combustion chamber 14 and the raw coal flue gas process chamber 19 respectively and are positioned at boiled water tank 27 respectively with the compositions such as high temperature beam tube flue 21 that are connected with combustion chamber 14 at the bottom of the dust chamber Room 24, combustion chamber 14 is an inverted pyramidal structures, and preheating beam tube flue 25 and high temperature beam tube flue 21 are pipe.

Below in conjunction with accompanying drawing the utility model is further described below.

Accompanying drawing is a structural representation of the present utility model.

Be arch at the bottom of the chamber of dust chamber 24 of the present utility model, the top, chamber is a plane, and locular wall has cleaning eye 5.The upper end of cigarette thorax 28 connects chimney 1, and the lower end is connected with an end of preheating beam tube flue 25, and the other end of preheating beam tube flue 25 is connected with top, the chamber of dust chamber 24.Preheating beam tube flue 25 is a pipe, and its tube chamber communicates with the cavity of smoke chamber 28 and dust chamber 24 respectively.Connect an end of high temperature beam tube flue 21 at the bottom of the dust chamber Room 24, the other end of high temperature beam tube flue 21 is connected with combustion chamber 14, and high temperature beam tube flue 21 is a pipe, and its tube chamber communicates with dust chamber 24 and combustion chamber 14 respectively.Because combustion chamber 14 is inverted pyramidal structures, so 14 upper ends, combustion chamber have become at the bottom of the gas approach back taper 18 naturally, high temperature beam tube flue 21 just connects on it.Second-time burning fire grate 13 is shelved in the bottom of combustion chamber 14, but raw coal flue gas process chamber 19 processes with combustion chamber 14 one.Water pipe furnace grate 29 is arranged on the bottom of raw coal flue gas process chamber 19.Object-catching chamber 12 is arranged at the bottom of combustion chamber 14, burnouts and cinder under falling with admittance, and cleanout door 11 is arranged in the object-catching chamber 12, opens this door with the cleaning cinder.On the wall body of raw coal flue gas process chamber 19, offer coal filling hole 7, water pipe furnace grate cleaning door 8 respectively, and the time this door closed, when will be, then open this door and get final product water pipe furnace grate 29 cleaning.14 locular wall is provided with and observes door 9 in the combustion chamber, to understand the combustion case in the combustion chamber 14.Water in the preheating water tank 26 enters boiled water tank 27 by the preheating water import 10 that is located on the boiled water tank 27 again by the outlet of the preheating water on it 4, pipeline 30.Because the outer wall of high temperature beam tube flue 27 soaks in the water that is embedded in the boiled water tank 27, the time just can on its wall, produce the water trowel used for plastering for a long time, can make manual removal by the manual removal mouth 6 that is located at boiled water tank 27 sidepieces to this.Owing to is arch at the bottom of the chamber of dust chamber 24 of the present utility model, so its cavity also is arch, be provided with cleaning eye 5 at the locular wall of dust chamber 24, its effect is that the flyash that will be deposited in the dust chamber 24 are removed; On cigarette thorax 28, offer ash removing opening 3, be accumulated in the coal dust of cigarette thorax 28 bottoms with removing.Preheating water water inlet 2 and preheating outlet 4 is set respectively in preheating water tank 26 upper and lower part, is connected with corresponding pipeline respectively; Be provided with steam (vapor) outlet 22, boiling water outlet 20 and heating circulating water outlet 17 respectively in the upper, middle and lower of boiled water tank 27 one, they are drawn by pipeline separately respectively, to be put to various uses.22 places are connected with blow-down pipe 23 at steam (vapor) outlet, when steam multiple pressure power is big in the boiled water tank 27, can not have pressure to guarantee the anti-stove that burns by it with excess steam emptying.The effect that is positioned at the sewage draining exit 15 of boiled water tank 27 bottom side is to get rid of dirt, keeps the cleaning in the boiled water tank 27.

The utility model enters preheating water tank 26 by water inlet 2 with water, enters boiled water tank 27 through preheating water outlet 4, pipeline 30, preheating water import 10 respectively again, waits to irritate the valve of blinding off a line to the waterline 31 on 30.On water pipe furnace grate 29, place coal-kindling-coal by coal filling hole 7, in raw coal flue gas process chamber 19, ignite, later on then as required and to water pipe furnace grate 29 stoking, fire coal after igniting falls on the second-time burning fire grate 13 from water pipe furnace grate 29, carry out second-time burning, the anti-wall 16 of boring rises the elevated temperature heat flue gas that burning is produced along the combustion chamber, enter that gas approach is counter bores at the end 18, through high temperature beam tube flue 21, flue gas expansion chamber 24, preheating beam tube flue 25, enter smoke chamber 28 then, through chimney 1 cigarette is effluxed again.In above-mentioned overall process, the water in boiled water tank 27, the preheating water tank 26 is distinguished boiled and preheating.If will be used for steamed rice, then draw and get final product by steam (vapor) outlet 22; If will be used for drinking-water, then draw and get final product by boiling water outlet 20; If need use warm water, then draw and get final product by the circulating water outlet 17 of warming oneself.For avoiding combustion chamber 14 can not fully carry out second-time burning because of oxygen supply is not enough, then can on chimney 1, connect a blower fan, also can directly on chimney 1, establish air door, as long as unlatching blower fan or air door just can reach oxygenation, in order to abundant burning.So few from the pollutant that chimney 1 is discharged, can reduce the air-polluting degree effectively.

The utility model is because after adopting said structure, has advantages such as heating surface area is big, effective, the uniform heat distribution of being heated, hot flue gas rising resistance is little, radiation effect is good.
