When the temperature of the flue gas is higher, a large amount of heat of the boiler can be taken away, and the operating economy of the boiler is seriously influenced; when the temperature of the flue gas is lower, the efficiency of the boiler is improved, but low-temperature corrosion is caused, and the service life of related equipment of the boiler is influenced. The above problems need to be solved.
The utility model has the following contents:
the utility model aims at overcoming the weak point that above-mentioned prior art exists, and provide an energy-efficient boiler cigarette wind automatic control system, it has solved the flue gas temperature too high or low problem excessively.
In order to solve the problem existing in the background art, the utility model adopts the following technical scheme: including the forced draught blower, the forced draught blower passes through the pipeline and is connected with air heater, and air heater passes through the pipeline and is connected with fan and coal pulverizer, and the fan passes through the pipeline and is connected with furnace, the coal pulverizer pass through the pipeline and be connected with the dust exhaust fan, the dust exhaust fan passes through the pipeline and is connected with furnace, furnace passes through the pipeline and is connected with the over heater, the over heater passes through the pipeline and is connected with the economizer, the economizer passes through the pipeline and is connected with the air preheater, the air preheater passes through the pipeline and is connected with the dust remover, the dust remover passes through the pipeline and is connected with the draught fan, the draught fan passes through the pipeline and is connected with the chimney.
The fan comprises a primary fan and a secondary fan, one end of the primary fan and one end of the secondary fan are respectively connected with the air preheater through pipelines, and the other ends of the primary fan and the secondary fan are respectively connected with the hearth through pipelines.
And a first valve and a second valve are respectively arranged on pipelines for connecting the primary fan and the secondary fan with the hearth.
The coal mill comprises a coal mill air heater and a coal mill air cooler, one end of the coal mill air heater and one end of the coal mill air cooler are respectively connected with an air preheater through pipelines, and the other end of the coal mill air heater and the other end of the coal mill air cooler are respectively connected with a powder discharge fan through pipelines.
The beneficial effects of the utility model are that reasonable in design, safe and reliable has solved the flue gas high temperature or has crossed low problem, improves fuel combustion efficiency, has still reduced carbon dioxide's emission simultaneously.
Description of the drawings:
fig. 1 is a schematic view of the connection structure of the present invention.
The specific implementation mode is as follows:
referring to fig. 1, the present invention specifically adopts the following embodiments: including the forced draught blower, the forced draught blower passes through the pipeline and is connected with air heater, and air heater passes through the pipeline and is connected with fan and coal pulverizer, and the fan passes through the pipeline and is connected with furnace, the coal pulverizer pass through the pipeline and be connected with the dust exhaust fan, the dust exhaust fan passes through the pipeline and is connected with furnace, furnace passes through the pipeline and is connected with the over heater, the over heater passes through the pipeline and is connected with the economizer, the economizer passes through the pipeline and is connected with the air preheater, the air preheater passes through the pipeline and is connected with the dust remover, the dust remover passes through the pipeline and is connected with the draught fan, the draught fan passes through the pipeline and is connected with the chimney. The fan comprises a primary fan and a secondary fan, one end of the primary fan and one end of the secondary fan are respectively connected with the air preheater through pipelines, and the other ends of the primary fan and the secondary fan are respectively connected with the hearth through pipelines. And a first valve and a second valve are respectively arranged on pipelines for connecting the primary fan and the secondary fan with the hearth. The coal mill comprises a coal mill air heater and a coal mill air cooler, one end of the coal mill air heater and one end of the coal mill air cooler are respectively connected with an air preheater through pipelines, and the other end of the coal mill air heater and the other end of the coal mill air cooler are respectively connected with a powder discharge fan through pipelines.
When this energy-efficient boiler cigarette wind automatic control system used, the forced draught blower sends into air heater with the air and preheats, the hot flue gas that leaves the boiler gets into air heater and preheats, and take place heat transfer between the air, the air admission coal pulverizer that is heated, then in getting into the furnace of boiler through a fan, mix with the fuel of burning here, the flue gas that the fuel burning produced flows through the over heater and just cools down, then cool down by a wide margin through the economizer again, and utilize the waste heat, later to the air preheater, and carry out dust removal treatment in the dust remover, flow to the chimney through the draught fan at last, arrange to the atmosphere.
And a coal mill air heater and a coal mill air cooler are arranged on the coal mill, are connected with the hearth through a powder discharge fan, and can recycle raw materials.
A first valve and a second valve are respectively arranged on pipelines for connecting the primary fan and the secondary fan with the hearth, so that the flow of flue gas can be controlled, and the emission of the flue gas can be controlled.
To sum up, this energy-efficient boiler cigarette wind automatic control system reasonable in design, safe and reliable has solved the too high or low problem of flue gas temperature, improves fuel combustion efficiency, has still reduced the emission of carbon dioxide simultaneously.
