Abstract
The utility model relates to a vertical cylindrical double-return hot-blast stove, which is mainly characterized in that a stove body is composed of an inner cylinder, a middle inner cylinder, a middle outer cylinder and an outer cylinder. The upper end of the inner cylinder is closed off, and the lower end of the inner cylinder is connected with the outer cylinder. The lower end of the middle inner cylinder is connected with the lower end of the middle outer cylinder, and a dust emission port and a flame lower exit port are opened. A hot air channel is formed by the extension of the upper part of the middle inner cylinder. The upper end of the middle outer cylinder is connected with the hot air channel. The flame exit ports are opened on the upper end of the inner cylinder and the upper end of the middle inner cylinder. The stove flame and the air all have double-return, which makes the cold air heated after preheated by going into the stove body; hence, the heat quantity can be utilized fully. The vertical cylindrical double-return hot-blast stove has high thermal efficiency and steady operation. The vertical cylindrical double-return hot-blast stove is applicable to dry and heat for productions of chemical industry, medicine, agricultural products, light industry, etc.
Description
The utility model belongs to a kind of air heating apparatus, particularly a kind ofly is used for the two backhaul hot-blast stoves of vertical barrel that chemical industry, medicine, agricultural byproducts, light industrial goods etc. carry out high temperature drying or heating.
The coal-fired two backhaul indirect hot-blast stoves of a kind of vertical barrel metallic object are disclosed in the CN87216988 patent document.This hot-blast furnace body only has two hot-air channels, and combustion gas is directly got rid of from the chimney of inner bag top, so the thermal efficiency is low, energy consumption is high.
The purpose of this utility model is to overcome deficiency of the prior art and a kind of thermal efficiency height, simple in structure, stable operation, two backhaul hot-blast stoves of vertical barrel reliable, applied widely fully are provided.
The purpose of this utility model is achieved in that
The structure of the two backhaul hot-blast stoves of vertical barrel is to install stove urceolus (8) on drop-bottom (1), installing inner core in the stove (6), middle urceolus (7) and inner core (5) in stove urceolus (8) inside, grate (2) is being adorned in the bottom of inner core (5), and the sidewall of urceolus (8) bottom has fire door a and cleaning door b.The upper end of middle urceolus (7) and the outer wall of middle inner core (6) are connected, the lower end is connected with middle inner core (6) arc, and has dust-exhausting port d in the bottom, and sidewall has outlet c under the flame gas, and outlet c place is installing flame gas and is gathering passage (3) under the flame gas of urceolus (8), is installing chimney (9) on its passage.The top seal camber of inner core (5), and have flame gas outlet e on the top of inner core (5) and middle inner core (6).Middle inner core (6) extends upward and constitutes hot-air channel (13), and passway h is a hot air outlet, is adorning power-failure protecting baffle plate (11) and (12) on its passage.The upper end of urceolus (8) and hot-air channel (13) constitute cool air inlet f, and are installing block cover (10) on the hot-air channel at f place.Outer wall at inner core (5), middle inner core (6) and middle urceolus (7) is installing equally distributed fin (4).
The utility model compared with prior art has following advantage:
1, because flame gas and heated air all adopt two return structures, therefore heat is fully used, has improved the thermal efficiency greatly.
2, since in middle urceolus and middle inner core junction and junction, inner core top all adopt thermal expansion arc syndeton, therefore can reduce thermal (temperature difference) stress greatly, prolong the shelf life of equipment.
3, be provided with dust-exhausting port at middle urceolus and middle inner core junction, therefore the dust that flame gas can be carried is in time removed totally, and is unimpeded to guarantee flame gas, thus the normal safe operation of the equipment of assurance.
4, the secondary cut protection device is set on hot-air channel, in case unexpected the power failure caused damage, ensures safety in production stove.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the utility model structural representation.
Below in conjunction with accompanying drawing the utility model embodiment is described in further detail:
The structure of the two backhaul hot-blast stoves of vertical barrel is to install stove urceolus (8) on drop-bottom (1), the inside of stove urceolus (8) is installing stove inner core (5), middle inner core (6), middle urceolus (7), the bottom of stove inner core (5) is installing grate (2), and the sidewall of stove urceolus (8) bottom has fire door a and cleaning door b.Middle inner core (6) extends upward and constitutes hot-air channel (13), middle urceolus (7) upper end is connected with the hot-air channel outer wall, the lower end is connected with middle inner core (6) arc, and have a dust-exhausting port d in the bottom, sidewall has outlet c under the flame gas, and installing flame gas at the c place and gather passage (3), installing chimney (9) on its passage.The top seal camber of inner core (5), and have flame gas outlet e on the top of inner core (5) and middle inner core (6).On the stove inner core (5) of oven body part, middle inner core (6) and middle urceolus (7), installing fin (4).Hot-air channel (13) and urceolus (8) constitute inlet of cold air f, are installing block cover (10) on the hot-air channel at f place, are also adorning power-failure protecting baffle plate (11) and (12) on the hot-air channel, and its hot-air channel mouth h is a hot air outlet.
The structural principle of the utility model hot-blast stove is, the flame that the stove fuel combustion produces makes the interior air heat of burner hearth to high temperature, combustion gas rises to roof of the furnace, the folder crack of inner core from the e mouth enters (6) and middle urceolus (7), enter flame gas by the c mouth and gather passage (3), discharge by chimney (9) at last, shown in dotted arrow among the figure.In the flame gas with dust deposition after can discharge from dust-exhausting port d, unimpeded to guarantee flame gas.Cold air enters from the f mouth of furnace roof portion, folder crack preheating between urceolus (8) and middle urceolus (7), rotate again to enter and heat by the folder crack between middle inner core (6) and the inner core (5), after the hot-air channel of furnace roof (13) is sent into air-introduced machine from hot air outlet h, send into the user by air-introduced machine again, shown in the solid arrow among the figure.As can be seen from the figure, flame gas and air are two backhauls and flow, make its flame gas passage and air duct all prolong one times than the one way stove, when particularly cold air enters the folder crack of urceolus (8) and middle urceolus (7) formation, promptly by the flame gas preheating in urceolus (7) from the e mouth enters and middle inner core (6) the folder crack, and then enter the folder crack heating that constitutes by inner core (5) and middle inner core (6), the heat of flame gas is fully used, with the minimizing heat loss, thereby the thermal efficiency of this stove is reached more than 80%.The hot air outlet temperature can reach more than 400 ℃, thereby has realized the purpose of efficient energy-saving.
