Abstract
The utility model provides a flue superheater. The flue superheater comprises a seamless steel tube, wherein the seamless steel tube comprises an inlet end and an outlet end; the seamless steel tube between the inlet end and the outlet end spirally bends and extends; and a reducing valve is connected to the inlet end. An explosion-proof casing is arranged at the periphery of the spiral section of the seamless steel tube. According to the utility model, a spiral superheater is formed by using the seamless steel tube; the explosion-proof casing is arranged outside the spiral section; the reducing valve is formed on the inlet end, after the seamless steel tube and the explosion-proof casing are arranged in the flue of a boiler, the saturated vapor entering into the seamless steel tube is heated through the flue gas in the flue of the boiler; and the superheated vapor is obtained at the outlet end of the seamless steel tube. The superheated vapor contains the heat energy obtained from the flue of the boiler, and the heat energy can be used for heating requirements in industrial production. By the flue superheater, the energy is saved, and the industrial production cost is reduced.
Description
Technical field:
The utility model relates to heating technique, relates in particular to surplus heat collection device, particularly a kind of flue superheater.
Background technology:
Generally all between 150 ℃～500 ℃, the heat that flue distributes all is wasted the temperature of boiler flue, so the industrial production cost that boiler participates in is higher, and energy resource consumption is more.
Summary of the invention:
The purpose of this utility model is to provide a kind of flue superheater, and described this flue superheater will solve the technical problem that boiler flue distributes in the prior art heat is wasted.
This flue superheater of the present utility model, comprise a seamless steel pipe, wherein, described seamless steel pipe comprises an entrance point and a port of export, seamless steel pipe between entrance point and the port of export is crooked the extension twist, is connected with pressure-reducing valve on the described entrance point.
Further, the periphery of the spiral section of seamless steel pipe is provided with an explosion-resistant enclosure.
Further, the seamless steel pipe between entrance point and the spiral section is straight tube, and the seamless steel pipe between the port of export and the spiral section is straight tube.
Operation principle of the present utility model is: the explosion-resistant enclosure of spiral section seamless steel pipe and periphery thereof is set in the flue of boiler, saturated vapor is passed into seamless steel pipe through behind the pressure-reducing valve, flue gas in the boiler flue is to the heating of the saturated vapor in the seamless steel pipe, at the port of export acquisition superheated steam of seamless steel pipe.Contain the heat energy that obtains in the boiler flue in the superheated steam, can be used for the demand for heat in the industrial production.
The utility model and prior art are compared, and its effect is actively with obvious.The utility model utilizes seamless steel pipe to consist of the spirality superheater, explosion-resistant enclosure is set outside spiral section, at entrance point pressure-reducing valve is set, after being set in the boiler flue, can utilize the flue gas in the boiler flue that the saturated vapor that passes into seamless steel pipe is heated, at the port of export acquisition superheated steam of seamless steel pipe.Contain the heat energy that obtains in the boiler flue in the superheated steam, can be used for the demand for heat in the industrial production.But the utility model energy savings reduces the industrial production cost.
Description of drawings:
Fig. 1 is the structural representation of flue superheater of the present utility model.
The specific embodiment:
Embodiment 1:
As shown in Figure 1, flue superheater of the present utility model, comprise a seamless steel pipe, wherein, described seamless steel pipe comprises an entrance point 1 and a port of export 2, seamless steel pipe between entrance point 1 and the port of export 2 is crooked the extension twist, is connected with the pressure-reducing valve (not shown) on the described entrance point 1.
Further, the periphery of the spiral section 3 of seamless steel pipe is provided with an explosion-resistant enclosure (not shown).
Further, the seamless steel pipe between entrance point 1 and the spiral section 3 is straight tube, and the seamless steel pipe between the port of export 2 and the spiral section 3 is straight tube.Described straight tube is connected with the spiral section 3 of seamless steel pipe by bend pipe 4 respectively.
The operation principle of present embodiment is: the explosion-resistant enclosure of spiral section 3 seamless steel pipes and periphery thereof is set in the flue of boiler, saturated vapor is passed into seamless steel pipe through behind the pressure-reducing valve, flue gas in the boiler flue is to the heating of the saturated vapor in the seamless steel pipe, at the port of export 2 acquisition superheated steams of seamless steel pipe.Contain the heat energy that obtains in the boiler flue in the superheated steam, can be used for the demand for heat in the industrial production.
Concrete, spiral section 3 includes 10 circle spirals at least.
