Description
Technical field
The utility model belongs to the technical field of structures of tubular air preheater, specially a kind of tubular preheater bobbin carriage knot
Structure.
Background technology
Tubular air preheater is to be handed over using flue gas heat come a kind of gas-gas heat of the air required for heating boiler burning
Parallel operation, it is important, indispensable part in station boiler.The main function of air preheater is to heat combustion air simultaneously
Exhaust gas temperature is reduced, improves boiler efficiency.The important function of one of which is that air is heated to certain temperature by flue gas, can make fuel
Dry and volatile matter effusion is accelerated.
When boiler uses the higher coal of moisture, the desiccant temperature that coal dust needs is higher, it is necessary to obtain about 380 DEG C of left sides
A right hot blast, it can just reach the requirement of pulverized coal preparation system drying capacity, and the secondary hot-air that air preheater comes out only needs
320 DEG C or so of offer goes to participate in burning, and the air outlet of existing tubular air preheater leads to boiler by different pipelines
First air, Secondary Air position so that First air, the temperature of Secondary Air position are identical, although the temperature of Secondary Air can obtain
Ensure, but the temperature of First air is relatively low so that the drying efficiency of coal dust is reduced, and then the thermal efficiency to burn declines.
In boiler using conventional tubular preheater, there is steel construction under every grade of bobbin carriage, in order to exchange heat fully, bobbin carriage height
It is unsuitable too high, and be made up of between every grade of bobbin carriage steel construction, expansion joint, a section flue.So it must be deposited between two-stage bobbin carriage
It is low in 2 meters or so of structural non-heat exchanging segment, space occupancy rate.
Utility model content
A purpose of the present utility model is in order to overcome the above-mentioned deficiencies of the prior art, and then to provide a kind of preheating of tubular type
Device channel structure, the utility model is simple in construction, can effectively improve between conventional pre-heater two-stage bobbin carriage and there must be 2 meters
The structural non-heat exchanging segment of left and right, the problem of causing space occupancy rate low, the structure can be made in the situation of identical heating surface area
Lower saving arrangement space.
The technical solution of the utility model：
A kind of tubular preheater channel structure, it is characterised in that including casing, flue, the first air inlet, the first air-out
Mouth, the second air inlet, the second air outlet, heat pipe, dividing plate, are provided with the dividing plate in the middle part of the casing, and the dividing plate will
The casing is separated into the first half and lower half, and the heat pipe is arranged in the casing, pass through and be fixedly installed on it is described every
On plate, first air inlet, the first air outlet are arranged on the lower half of the casing, second air inlet, the second air-out
Mouth is arranged on the first half of the casing, and the flue is arranged on the side of the casing.
Further, first air outlet and second air inlet are arranged on the homonymy of the casing, the flue
It is arranged on the side of first air outlet and second air inlet, it is first air inlet, first air outlet, described
Second air inlet and second air outlet form U-typed air duct with the flue.
The utility model has the advantages that relative to prior art：Tubular preheater pipe disclosed in the utility model
Box structure, including casing, flue, the first air inlet, the first air outlet, the second air inlet, the second air outlet, heat pipe, dividing plate,
Dividing plate is provided with the middle part of casing, casing is divided into the first half and lower half, heat pipe is arranged in casing and passes through dividing plate and fixation
On dividing plate, the first air inlet and the first air outlet are arranged on the lower half of casing, and the second air inlet and the second air outlet are set
In the first half of casing, the first air outlet and the second air inlet are arranged on the homonymy of casing, and flue is arranged on the first air outlet side,
The first air inlet, the first air outlet, the second air inlet and the second air outlet and flue form U-typed air duct simultaneously, this knot
In structure, central dividing plate and UNICOM air channel are set up on one group of bobbin carriage, single bobbin carriage is undergone the both direction of one-time continuous
Heat absorption, be effectively improved the structural non-heat exchanging segment that there must be 2 meters or so between conventional pre-heater two-stage bobbin carriage, cause space
The problem of occupancy is low, the structure can be made to save arrangement space in the case of identical heating surface area.
Additional aspect and advantage of the present utility model will be set forth in part in the description, partly by from following description
In become obvious, or recognized by the practice of utility model.
