The method comprises the following steps: the flue gas (about 60 ℃) from the wet desulphurization outlet passes through GGH arranged at the outlet of an SCR device, the temperature of the flue gas is heated to 170 ℃, then the flue gas enters a steam/flue gas heater, the temperature of the flue gas is heated to more than 220 ℃ before an ammonia spraying grid, the flue gas enters a low-temperature catalyst, the temperature of the flue gas from the catalyst outlet is reduced to about 160 ℃ after the flue gas is subjected to GGH, and finally the flue gas enters a draught fan and is exhausted to the atmosphere.
The waste incineration power station has the advantages that the exhaust gas temperature is high, waste of waste heat of the flue gas is caused on one hand, the flue gas temperature is high on the other hand, the actual volume flow of the flue gas is large, the power consumption of the induced draft fan is increased, the power consumption of the plant is increased, and the power consumption of the induced draft fan accounts for about 30% of the power consumption of the whole plant.
In addition, when the garbage generator set runs, primary air from the garbage pit is heated to about 180-190 ℃ through the upper air preheater and the lower air preheater so as to meet the requirement of combustion of the incinerator. The heating sources of the upper air preheater and the lower air preheater are high-pressure steam from a steam drum and extraction steam from a steam turbine. The primary air heating system has the defect that the occupied steam which can be used for the steam turbine to do work is used for heating the primary air, so that the heat consumption of the steam turbine is increased.
With the increasingly saturated construction scale of domestic garbage power plants and the gradual promotion of garbage classification policies, garbage power generation enterprises need to pay more and more attention to the economy of garbage power generation while completing garbage treatment tasks. Therefore, how to fully utilize the waste heat of the exhaust gas of the waste incineration power station and reduce the heat consumption of the steam turbine to improve the economy of the whole plant is a subject worthy of intensive research in the technical field of waste power generation in the future.

Detailed Description
The invention is described in further detail below with reference to the accompanying drawings:
referring to fig. 1, the deep flue gas waste heat utilization system of a waste incineration power station comprises an inlet primary air pipeline of an air preheater, a first three-way valve 1, a first regulating valve 3, a gas-gas heat exchanger 13, a second three-way valve 2, a superior air preheater 6, a subordinate air preheater 7, a primary fan 11, an incinerator 18, a steam drum steam supply pipeline, a steam turbine steam extraction pipeline, a wet deacidification flue gas supply pipeline, a second flue gas reheater 14, a first flue gas reheater 15, a steam/flue gas heater 16, an SCR reactor 17 and a chimney 19; an inlet primary air pipeline of the air preheater is communicated with an inlet of a first three-way valve 1, a first outlet of the first three-way valve 1 is communicated with a first inlet of a second three-way valve 2 through a first regulating valve 3 and a heat absorption side of a gas-gas heat exchanger 13, a second outlet of the first three-way valve 1 is communicated with a second inlet of the second three-way valve 2 through a heat absorption side of a superior air preheater 6 and a heat absorption side of a subordinate air preheater 7 in sequence, an outlet of the second three-way valve 2 is communicated with an incinerator 18 through a primary fan 11, a steam drum coming steam pipeline is communicated with a heat release side of the superior air preheater 6, and a steam extraction pipeline of a steam turbine is communicated with a heat release side of the subordinate air; the wet deacidification flue gas pipeline is communicated with an inlet of an SCR reactor 17 through a heat absorption side of a second flue gas reheater 14, a heat absorption side of a first flue gas reheater 15 and a steam/flue gas heater 16, an outlet of the SCR reactor 17 is communicated with a heat release side inlet of a gas-gas heat exchanger 13 through a heat release side of the first flue gas reheater 15 and a heat release side of the second flue gas reheater 14, and a heat release side outlet of the gas-gas heat exchanger 13 is communicated with a chimney 19.
A first thermometer 8 is arranged on a primary air pipeline at the inlet of the air preheater; the outlet of the second three-way valve 2 is communicated with the incinerator 18 through a second thermometer 9 and a primary fan 11.
The heat release side outlet of the gas-gas heat exchanger 13 is communicated with a chimney 19 through a draught fan 12; and a third thermometer 10 is arranged on a pipeline between the induced draft fan 12 and the chimney 19.
A second regulating valve 4 is arranged on a steam pipeline from the steam drum; and a third regulating valve 5 is arranged on the steam extraction pipeline of the steam turbine.
When the incinerator 18 works, when the rated mechanical load of the incinerator 18 is achieved, the air side resistance is about 800-1000 Pa, namely the differential pressure between the second three-way valve 2 and the first three-way valve 1 is 800-1000 Pa, and the flue gas self-flow can be achieved by utilizing the differential pressure between the inlet and the outlet of the air side in the upper air preheater 6 and the lower air preheater 7;
when the unit operates daily, the outlet smoke temperature of the induced draft fan 12 is 155-170 ℃, and the lowest safe temperature at which no colored smoke plume appears is determined by analyzing the moisture content and the acid dew point temperature of the inlet smoke of the induced draft fan 12 and combining local climatic conditions. For example, if the minimum safe temperature is 110 ℃, the temperature of the exhaust gas at the outlet of the induced draft fan 12 needs to be controlled to be above 110 ℃;
the minimum safe temperature is used as a first control variable to adjust the air flow through the first regulating valve 3 to prevent white smoke from occurring. On the basis that the exhaust gas temperature is higher than the minimum safe temperature, the inlet temperature of the primary air fan 11 is used as a second control variable, and the temperature of air entering the primary air fan 11 is controlled to be 180-190 ℃ by adjusting the steam flow of the steam drum entering the second adjusting valve 4 or the air exhaust flow of the steam turbine of the third adjusting valve 5, so that the combustion requirement of the incinerator 18 is met.
