Description
Technical Field
The invention belongs to the technical field of sludge drying, and relates to an atomization device for mixing gas and solid phases in a double chamber.
Background
With the acceleration of the urbanization process and the continuous improvement of the living standard of people, the sewage treatment capacity is increased sharply, sludge is a byproduct of sewage treatment, and the yield is increased. At present, the ecological environment protection is promoted to the unprecedented strategic height by the country, the original modes of treating sludge by simple treatment and then outward transport and landfill, or simple composting and the like are completely not suitable for the requirements of ecological civilization construction in China, the sludge is properly treated and treated by the environmental protection department and brought into the emission reduction assessment of the total amount of sewage, the policy is changed from 'heavy water light sludge' to 'heavy water sludge', and the recycling and harmless process of the sludge treatment is driven.
The sludge has high water content and low heat value, contains a large amount of complex harmful components such as viruses, pathogens, microorganisms, heavy metals and the like, and needs to be subjected to stabilization, reduction and harmless treatment. A 'biomass utilization and incineration' disposal mode is popularized in large and medium-sized cities with shortage of land resources, wherein the drying incineration is a mainstream process for solving the problems of large amount of accumulation, limited digestion and export and the like.
The sludge drying and incinerating technology is a technology for reducing the water content of sludge to a certain degree to reach a certain calorific value and then carrying out incineration treatment, so that the sludge drying and incinerating technology is divided into two stages. The existing drying technology adopts two modes of direct drying, indirect drying and the like, wherein the direct drying mode is mainly to introduce high-temperature flue gas into sludge to evaporate water, such as a rotary drum drying technology, a belt drying technology, a fluidized bed drying technology and the like; indirect drying is mainly characterized in that the sludge attached to the other surface of the metal cavity is evaporated by heating the metal cavity through steam or heat conduction oil, such as paddle type drying technology, disc type drying technology and the like. Both of these approaches have common features: small treatment scale, high cost, high equipment failure rate, multiple auxiliary facilities and the like, thereby restricting the wide application of the sludge drying technology.
Considering that the direct drying efficiency is highest, if the sludge is atomized into fine particles to be directly sprayed into the high-temperature flue gas, the sludge with small particle size and the high-temperature flue gas directly exchange heat to be rapidly dried, the mode is direct, the required equipment is few, but the key equipment is a device capable of atomizing the sludge into small particle size. Considering that the sludge has high viscosity, strong corrosivity and poor fluidity, the sludge needs to be refined into small particles with certain diameters (the particle size is less than or equal to 500um), and the atomization device needs a special structure to meet the requirement of sludge atomization.
