Description
Technical Field
The utility model belongs to the technical field of the heating of rubbish pond, in particular to utilize system of sludge drying flue gas waste heat heating rubbish pond.
Background
The north of China is cold in winter, the temperature is kept below zero for a long time, the collected garbage is very easy to freeze, and after the garbage is thrown into a garbage pool, the temperature in the pit is equivalent to the outdoor temperature. When the temperature is low, the garbage is not easy to melt, the garbage fermentation is seriously influenced, and the heat value of the garbage entering the furnace can be reduced. The low calorific value of the garbage entering the incinerator can reduce the temperature of the incinerator, influence the incineration of the incinerator and possibly cause the shutdown accident in serious cases. In order to ensure that the temperature of the hearth of the incinerator is kept at 850 ℃/2s, an auxiliary burner is required to be put into for supporting combustion, the fuel consumption is increased, and the operation cost is increased. The problem of low temperature of the garbage pool in winter is solved, and the garbage power plant has great significance in guaranteeing stable operation of the garbage power plant and improving operation efficiency.
In the prior art, a common heating method for a garbage pool comprises the following steps: the method I utilizes steam and furnace wall cooling air as main heat sources to supply heat to the garbage pit and improve the temperature in the pit. And secondly, extracting hot air from the hot primary air or the hot secondary air to heat the garbage. And thirdly, spraying the boiler blow-off water into a garbage pool to directly heat the garbage. And fourthly, heating the percolate in the garbage pool by using steam through a dividing wall type heat exchanger, and spraying the percolate back into the garbage pile.
However, the method has the following defects that the first method has high steam heat quality and high available value, adopts steam as a heating heat source, has high cost, can increase the heat consumption of the whole plant and reduce the heat efficiency of the power plant; the furnace wall cooling air can be converged with primary air under the normal condition to enter the hearth, and if the primary air is extracted from the garbage pool, the steam amount for heating the primary air can be increased, and the work done by a steam turbine is reduced. In the second method, the heat sources of the hot primary air and the hot secondary air are both from the steam extraction of the steam turbine, and if the heat sources are extracted to heat the garbage pool, the steam extraction quantity of the steam turbine is correspondingly increased, and the work of the steam turbine is reduced. For the third method, the humidity in the garbage pool is increased, the corrosion risk of equipment is increased, the infiltration liquid amount is increased, and the treatment cost of the infiltration liquid is increased. And for the fourth method, the leachate has more impurities, so that the heat exchanger is easy to be scaled and blocked, and the maintenance cost is high.
Meanwhile, researches show that the sludge drying flue gas contains a large amount of water vapor, and in order to reduce the humidity of the flue gas, the temperature of the flue gas must be reduced, and the water vapor is condensed into water. Usually, circulating water is used as a cooling medium to exchange heat with flue gas in a condenser. The circulating water is heated and then sent to a cooling tower for cooling, and then sent back to a condenser to form a closed circulating system. The latent heat of vaporization of water vapor is large, and a large amount of heat is released in the condensation process. The circulating water absorbs the heat of the flue gas, and then the flue gas is sent to the cooling tower for cooling, and the heat is dissipated to the atmosphere, so that a large amount of heat is wasted, and the method is not economical. However, the temperature of the circulating water is only more than 40 ℃, which belongs to a low-quality heat source and has low available value, so that no good method is available for utilizing the part of heat at present.
Therefore, how to solve the problem of low temperature of the garbage pool and simultaneously consider economy and environmental protection is a technical problem to be solved urgently by technical personnel in the field.
