Abstract

The utility model provides an improve device of combustion-supporting air temperature, including burning furnace and heat exchanger, burn the flue gas outlet end of burning furnace and pass through the heating gas inlet connection of flue gas pipeline with the heat exchanger, the inlet end of heat exchanger is the air inlet point, and gives vent to anger the end and pass through high temperature air pipeline and burn the combustion-supporting gas inlet connection of burning furnace. The utility model discloses for device before, cancel the steam boiler, the high temperature flue gas need not earlier to the water heating in the steam boiler and form steam, but the high temperature flue gas directly lets in the heat exchanger and lets in combustion-supporting in the incinerator after heating external low temperature air to certain temperature, the mode of this kind of heating is convenient direct, low temperature air can the direct heating more than 300 ℃, and the heating methods before generally heat to 100 ℃, but high temperature air gets into combustion-supporting of high efficiency in the incinerator, combustion-supporting efficiency has been improved greatly, and the high-usage of the while temperature flue gas, the high-usage of the energy.

Description

Device for increasing temperature of combustion air
Technical Field
The utility model relates to an environmental protection field specifically is a device for improving combustion air temperature.
Background
Admittedly useless need use fire-retardant air when burning in the incinerator, and directly introduce combustion-supporting in the incinerator with external low temperature air, because the air temperature is low then the inefficiency that begins to burn, along with the rising of inside combustion air temperature, then the efficiency of burning risees gradually, leads to the long and inefficiency of process time of whole burning like this, then leads to the utilization ratio of the energy low, consequently need just let in combustion-supporting in the incinerator after combustion air heats to certain temperature earlier. This company adopts the flue gas that burns burning furnace incineration production to steam boiler heating steam production before, and steam passes through the mode of heat exchanger to external low temperature air heating again and lets in burning furnace combustion-supporting behind the air heating to certain temperature, but this kind of mode is limited to the temperature that low temperature air heating promoted, and need form high temperature steam simultaneously, the low-usage of high temperature flue gas, the low-usage of the energy. Therefore, the technical personnel of the company propose a device for increasing the temperature of the comburent air to solve the technical problems that existed before.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an improve combustion air temperature's device to solve the problem that proposes among the above-mentioned background art.
In order to solve the technical problem, the utility model provides a following technical scheme: the device for improving the temperature of combustion-supporting air comprises an incinerator and a heat exchanger, wherein a flue gas outlet end of the incinerator is connected with a heating gas inlet end of the heat exchanger through a flue gas pipeline, an air inlet end of the heat exchanger is an air inlet end, and an air outlet end of the heat exchanger is connected with a combustion-supporting gas inlet end of the incinerator through a high-temperature air pipeline.
And a high-temperature flue gas filter is additionally arranged on the flue gas pipeline.
Compared with the prior art, the utility model discloses the beneficial effect who reaches is: the utility model discloses for device before, cancel the steam boiler, the high temperature flue gas need not earlier to the water heating in the steam boiler and form steam, but the high temperature flue gas directly lets in the heat exchanger and lets in combustion-supporting in the incinerator after heating external low temperature air to certain temperature, the mode of this kind of heating is convenient direct, low temperature air can the direct heating more than 300 ℃, and the heating methods before generally heat to 100 ℃, but high temperature air gets into combustion-supporting of high efficiency in the incinerator, combustion-supporting efficiency has been improved greatly, and the high-usage of the while temperature flue gas, the high-usage of the energy.

The accompanying drawings are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification. In the drawings:
FIG. 1 is a schematic structural view of a device for increasing the temperature of combustion air according to the present invention;
FIG. 2 is a schematic structural view of the combustion air temperature increasing device of the present invention before improvement;
in the figure: 1, an incinerator; 2, a heat exchanger; 3 a flue gas pipeline; 4, a high-temperature air pipeline; 5, a high-temperature flue gas filter; 6 steam boiler.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, the present invention provides a technical solution: the device for improving the temperature of combustion-supporting air comprises an incinerator 1 and a heat exchanger 2, wherein the flue gas outlet end of the incinerator 1 is connected with the heating gas inlet end of the heat exchanger 2 through a flue gas pipeline 3, the gas inlet end of the heat exchanger 2 is an air inlet end, and the gas outlet end of the heat exchanger is connected with the combustion-supporting gas inlet end of the incinerator 1 through a high-temperature air pipeline 4.
The high-temperature flue gas filter 5 is additionally arranged on the flue gas pipeline 3, high-temperature gas generated by the incinerator is filtered by the high-temperature flue gas filter 5 and then introduced into the heat exchanger 2 to heat external low-temperature air, and solid particles in the high-temperature flue gas can be effectively prevented from scaling on the inner wall of the heat exchange pipe of the heat exchanger 2 to block the heat exchange pipe.
The utility model discloses for device before (as shown in fig. 2), steam boiler 6 has been cancelled, and the high temperature flue gas need not earlier to the water heating in steam boiler 6 and form steam, but the high temperature flue gas directly lets in heat exchanger 2 and lets in after heating external low temperature air to certain temperature and burn burning furnace 1 internal combustion-supporting, and the mode of this kind of heating is convenient direct, and low temperature air can directly heat more than 300 ℃, and the general heating of preceding heating methods is to 100 ℃.
It is noted that relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions.
