Abstract

The invention discloses a household waste energy utilization and pollutant high-efficiency control system. A pyrolysis gasifier is connected with a semi-dry desulfurization tower through a second combustion chamber, a two-section type water wall and a quenching chamber in sequence. A gravity sedimentation chamber is arranged in an intermediate flue gas pipeline of the two-section type water wall.A water pipe at an outlet of the two-section type water wall is connected with a water supply pipe of the quenching chamber through a cooling tower and a water pump in sequence. Desulfurization and dechloridation treatment is carried out on flue gas through the semi-dry desulfurization tower. with the household waste energy utilization and pollutant high-efficiency control system, ultra-low pollutant emission can be implemented; because a semi-dry rotational flow desulfurization technology is taken for use, the through-flow time of the flue gas is prolonged, and the efficiency of desulfurization and dechloridation is improved without wastewater discharge; and furthermore, because the two-section type water wall is taken for use, ammonia injection is carried out rotationally in a rear section, emission of nitrogen oxide is reduced, the temperature of denitrification is taken under control as well, and the efficient denitrification effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of waste pollutant control and heat recovery, and in particular relates to a domestic waste energy utilization and high-efficiency pollutant control system. Background technique [0002] With the accelerated pace of urbanization in my country, the amount of municipal solid waste has increased rapidly. How to effectively dispose of domestic waste has become a major problem faced by city managers. Due to the small land and large population in our country, the traditional domestic waste landfill disposal method is facing the dilemma of increasingly difficult site selection. [0003] In order to achieve the goal of reducing, reusing, and harmless municipal solid waste treatment, the construction of solid waste incineration power plants is becoming the first choice of city managers. However, when domestic waste is put into a waste incineration power plant for incineration, a lot of highly polluting soot polluta...
