According to the hot-blast stove, the maximum flame can obtain enough spaces, combustion is completely full, in addition micro negative pressure can be produced in the combustion chamber so that stable flames are obtained, and tempering accidents are avoided.
Description
Technical field
The utility model relates to a device in the paper pulp moulding product production system, relates in particular to a kind of novel supporting combustion gas direct-heating type hot-blast stove of paper pulp molding drying line.
Background technology
Be illustrated in figure 1 as the schematic diagram of the direct heated type hot-blast stove of natural gas in the prior art, the direct heated type hot-blast stove of this natural gas comprises gas burner 1, combustion chamber 2, air inlet 3, air outlet 6.Combustion chamber 2 comprises that fan housing 4(length l 1 is 1000mm, and diameter d is 400mm) and outer cylinder body 5(length l 2 be 1995mm).Air inlet 3 uses for connecing circulating fan.During the successful normal combustion of burner 1 igniting, in fan housing 4, can form the flame 7 of certain-length and diameter, the cool ambient air b of high-temperature flue gas that burning is produced and air inlet 3 inputs mixes the hot-air c of uniform temperature from air outlet 6 outputs with 90 ° of angles (indicating with " a "), hot-air c output enters drying line as drying medium.The relevant position of drying line is equipped with temperature sensor and inserts PLC, finishes adjusting to the concrete size of flame according to setting program by burner control system, thereby reaches the purpose of regulating heat of mixing air themperature, to satisfy the actual temp demand of drying line.
Yet the direct heated type hot-blast stove of above-mentioned natural gas of the prior art has following defective:
1. fan housing 4 length l 1 and diameter d do not satisfy maximum flame size, thereby cause imperfect combustion, have black smoke to emerge from the combustor flange port on the one hand; Hong Gan paper matrix product surface has residual carbide on the other hand.
2. the high-temperature flue gas that produced of burning is with after the cool ambient air of air inlet 3 inputs is mixed with 90 ° of angles, generation malleation in the combustion chamber.In order to obtain stable flame and to guarantee exerting oneself and avoiding tempering of burner, must improve natural gas supply pressure and overcome malleation in the combustion chamber, the increasing of burner valve group bore, steam line and the raising of auxiliary facility voltage withstand class etc. of Yin Faing directly cause the drying line cost to rise thus.Improve the hidden danger that natural gas supply pressure also brings secure context indirectly in addition, this point can not be ignored.
For this reason, need overcome above-mentioned defective, a kind of improved combustion gas direct-heating type hot-blast stove is provided.
Summary of the invention
The purpose of this utility model is to provide a kind of combustion gas direct-heating type hot-blast stove, and it can make maximum flame obtain enough spaces, thereby burning cmpletely; And it can improve mixed wind mode in the combustion chamber, makes to produce little negative pressure in the combustion chamber under certain supply gas pressure, thereby obtains stable flame, avoids tempering to cause a serious accident.
For achieving the above object, the utility model adopts following technical scheme:
Combustion gas direct-heating type hot-blast stove comprises burner, combustion chamber, air inlet and air outlet, and described combustion chamber comprises outer cylinder body and fan housing, and described outer cylinder body forms inner chamber; Described burner is arranged on the end of described outer cylinder body and the combustion head of described burner stretches in the described inner chamber; One end of described fan housing is fixed on the respective end of described outer cylinder body and around being sheathed on described combustion outside the combustion head of device, described fan housing has certain length with outside the flame that covers on described combustion head formation; Described air inlet and described air outlet are connected on the described outer cylinder body and with the described inner chamber of described outer cylinder body formation and are communicated with; Wherein, the direction of described air inlet becomes the angle of 30 degree with the flame direction that the combustion head of described burner forms; The size of described fan housing is greater than the full-size of the flame of described combustion head formation.
The beneficial effects of the utility model are: because the size of fan housing is greater than the full-size of flame, thereby can make burning cmpletely, prevent to produce black smoke and residual carbide; And because air inlet becomes 30 degree angles with the direction of flame, after the cool ambient air of the high-temperature flue gas that produced of burning and air inlet input is spent angles and is mixed with 30, can under certain supply gas pressure, make to produce little negative pressure in the combustion chamber, thereby obtain stable flame, avoid tempering to cause a serious accident.
Description of drawings
The schematic diagram of the direct heated type hot-blast stove of Fig. 1 natural gas of the prior art.
Fig. 2 is the schematic diagram of the utility model combustion gas direct-heating type hot-blast stove.
The specific embodiment
Below in conjunction with accompanying drawing, introduce preferred embodiment of the present utility model in detail.
As shown in Figure 2, combustion gas direct-heating type hot-blast stove comprises burner 10, combustion chamber 20, air inlet 30 and air outlet 60.Wherein, combustion chamber 20 comprises outer cylinder body 50 and fan housing 40, and outer cylinder body 50 forms inner chamber, and burner 10 is arranged on an end end of outer cylinder body 50 and the combustion head of burner 10 stretches in the inner chamber of outer cylinder body 50, thereby the flame of combustion head is burnt in inner chamber.
Wherein, an end of fan housing 40 is fixed on the respective end (end that promptly connects burner 10) of outer cylinder body 50 and around being sheathed on combustion outside the combustion head of device 10, and fan housing 40 has certain length with outside the flame that covers on combustion head and form.Preferably, in the present embodiment, outer cylinder body 50 is a generally cylindrical body shape, and the fan housing 40 that is arranged on its end is also for cylindric, the axis of the axis of fan housing 40 and outer cylinder body 50 point-blank, and the combustion head of burner 10 just is arranged on this straight line.
In order to make flame combustion abundant, do not produce black smoke or residual carbide, the size of this fan housing 40 should be greater than the full-size of flame.In the present embodiment, the principal length L2 of outer cylinder body 50 is 1995mm, and the length L 1 of fan housing 40 is 1500mm, and the diameter D of fan housing 40 is 500mm, and fan housing 40 just increases, thereby can make sufficient combustion than diameter increase of the prior art, length like this.Certainly, in other embodiment of the utility model, can look actual conditions such as different combustion gas situations, the size of fan housing and outer cylinder body is adjusted design.
As shown in Figure 2, air inlet 30 and air outlet 60 are connected on the outer cylinder body 50 and with the inner chamber of outer cylinder body 50 formation and are communicated with.Wherein, the direction of air inlet 30 becomes the included angle A of 30 degree with the flame direction that the combustion head of burner 10 forms, that is the axis of air inlet 30 becomes 30 degree angles with the axis of fan housing 40.Like this, air inlet 30 feeds cold air B by circulating fan the inner chamber of outer cylinder body 50, being 30 degree angles with hot-air that the flame of combustion head produces mixes and forms hot-air C and 60 export from the gas outlet, under certain gas supply pressure effect, in inner chamber, produce little negative pressure, thereby can make flame stabilization, and prevent the generation of tempering phenomenon, avoid accident.
