Description
Technical field
The utility model belongs to high-temperature air preheater technical field, and in particular to a kind of tube-shell type high-temperature air preheater
With reducing heat exchanger tube.
Background technology
In nowadays traditional high-temperature air preheater, its heat exchanger tube is generally used with footpath straight tube structure, due to some lifes
The particularity of production. art, has viscous medium by the gas in pipe, easily produces the situation that attached wall plugging declines heat exchange efficiency,
And equipment enlarging, heat exchanger tube is longer, and gas makes the volume of gas change, circulating because changing greatly for temperature
In the case that section is identical, the flow velocity of gas will change, and the mobility and pressure differential to gas can also change.Separately
Outside, it is swollen to eliminate material since the particularity of structure on one end of every heat exchanger tube, it is necessary to set single single tube compensator
Swollen stress, the spacing that this is allowed between heat exchanger tube is larger, for the more high-temperature air preheater of heat exchanger tube number, then means
Specification bigger is needed, the part such as the thicker housing of thickness and tube sheet, greatly increases equipment manufacturing costs.
Utility model content
The purpose of this utility model is that：Solve above-mentioned deficiency of the prior art, there is provided a kind of stable, cost is more
Low tube-shell type high-temperature air preheater reducing heat exchanger tube.
To achieve these goals, the technical solution adopted in the utility model is：A kind of tube-shell type high-temperature air preheater
With reducing heat exchanger tube, including heat exchange pipe body, single tube compensator and tube sheet, the heat exchange pipe body includes the first noumenon and the
Two bodies, the first noumenon are coaxially disposed with second body, and the radius of the first noumenon is less than described second
The radius of body, heating agent outlet is provided with the top of the first noumenon, the bottom of second body is provided with heating agent
Import, the single tube compensator are arranged on the first noumenon lateral wall, are provided with the single tube compensator
Protection pipe, is additionally provided with casing on the lateral wall of the first noumenon, the casing positioned at the heating agent outlet and
Between the protection pipe, the casing is connected with the tube sheet.
Further, the first noumenon and second body by integral forming.
Further, the shape of the first noumenon and the cross section of the second body junction is tubaeform.
Further, single tube compensator is bellows.
By adopting the above-described technical solution, the beneficial effects of the utility model are：The high temperature air of the utility model is pre-
Hot device, by the way of reducing is carried out in the one end for having single tube compensator exchange heat pipe, i.e., the radius of the first noumenon is less than second
The radius of body, the length of reducer, that is, the first noumenon can be definite to design according to actual requirement, to avoid flue gas in low temperature
Because volume change causes change in flow the change of mobility and pressure differential occurs for section, ensures by varying the radius of heat exchanger tube
Gas in heat exchanger tube at the uniform velocity by reducing the situation that the attached wall of gas causes plugging.The heat exchanger tube of the utility model can be with
The effective spacing for reducing the heat exchanger tube in high-temperature air preheater, on the premise of pre-heat effect is not reduced, reduces high temperature
The volume of air preheater, so that equipment production cost is saved, to improve the competitiveness of product in market.

Embodiment
Reference Fig. 1, illustrates the embodiment of the utility model.
To achieve these goals, the technical solution adopted in the utility model is：A kind of tube-shell type high-temperature air preheater
With reducing heat exchanger tube, including heat exchange pipe body 1, single tube compensator 2 and tube sheet 3, the heat exchange pipe body 1 includes the first noumenon
11 and second body 12, the first noumenon 11 be coaxially disposed with second body 12, the radius of the first noumenon 11
Radius the first noumenon 11 less than second body 12 is integrally formed with second body 12, and the first noumenon 11
Shape with the cross section of 12 junction of the second body is tubaeform, and the top of the first noumenon 11 is provided with heating agent and goes out
Mouth 4, Heating medium 5 is provided with the bottom of second body 12, and the single tube compensator 2 is arranged on the first
On 11 lateral wall of body, which is used for the thermal expansion amount for compensating heat exchanger tube, is set on the single tube compensator 2
There is protection pipe 6, casing 7 is additionally provided with the lateral wall of the first noumenon 11, the casing 7 is located at the heat
Between matchmaker outlet 4 and the protection pipe 6, which is connected with the tube sheet 3.
Preferably, single tube compensator 2 is bellows.
The operation principle of the utility model：Using the utility model device heat exchanger tube when, high-temperature gas from heating agent into
Mouth 5 is flowed into heat exchanger tube, after making the Cryogenic air preheating in the outside of the second body of heat exchanger tube 12 using heat radiation, then flows to first
Body 11, from 4 outflow of heating agent outlet；Since the temperature of flue gas in the second body 12 is higher, the radius of the second body 12 is larger, first
The temperature of flue gas is relatively low in body 11, its radius of the first noumenon 11 is smaller, the gas in heat exchanger tube because temperature change compared with
Greatly, the volume of gas is changed, when gas flows to from the second body 12 of large radius the first noumenon 11 of minor radius, ensure
High-temperature gas in heat exchanger tube at the uniform velocity passes through.
The high temperature section of heat exchanger tube and low-temperature zone are arranged to different radiuses by the utility model device, avoid flue gas low
Because volume change causes change in flow the change of mobility and pressure differential occurs for temperature section, while ensure that the gas in heat exchanger tube
At the uniform velocity by also reducing the attached wall of gas and causing the situation of plugging；Also on the premise of pre-heat effect is not reduced, high temperature is reduced
The volume of air preheater, saves equipment production cost, improves the competitiveness of product in market.
