Problems solved by technology
The general heat recovery device requires a stable heat supply in the furnace. For example, the heat recovery device for heating water has a fixed water supply. If the temperature in the furnace is too high, it will not be able to fully absorb heat. If the water temperature is too low, it will cause the water temperature to be too low, which will affect the use of hot water
Due to the different components of different sludges, the temperature of the furnace cannot be accurately controlled only by controlling the moisture content in the sludge, which is not conducive to energy saving and emission reduction

Embodiment Construction
[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments: see Figure 1 to Figure 6, a sludge drying and incineration integrated equipment, including an incinerator body 1, a vertical smoke exhaust channel 2 is arranged on the top of the incinerator body 1, and a heat recovery device 3 is penetrated in the incinerator body 1. In this embodiment, the heat The recovery device 3 is a pipeline for heating water. The exhaust channel 2 is connected with a first hopper 6 and a second hopper 7 through the first feeding channel 4 and the second feeding channel 5, respectively. The first feeding channel 4 and the second feeding channel A first screw conveying shaft 41 and a second screw conveying shaft 51 are respectively rotatably arranged in the feeding channel 5. The first screw conveying shaft 41 is driven by a motor, and two first fixing discs 42 are fixed at the tail of the first screw conveying sh...

Abstract
The invention discloses a sludge drying and incineration integrated equipment and a sludge incineration method thereof. The channel is connected with the first hopper and the second hopper respectively through the first feed channel and the second feed channel, and the first screw conveying shaft and the second screw conveyor shaft are respectively rotated in the first feed channel and the second feed channel. The transmission ratio of the conveying shaft, the first screw conveying shaft and the second screw conveying shaft can be automatically adjusted. When the temperature rises, the input ratio of the semi-dry sludge decreases, and when the temperature drops, the input ratio of the semi-dry sludge increases. In this way, the temperature inside the incinerator body is maintained at the set temperature, so as to prevent excessive fluctuations in the furnace temperature due to different sludge components, so that the heat recovery device can absorb heat stably, which is conducive to energy saving and emission reduction.
Description
technical field [0001] The invention belongs to the technical field of sludge incineration equipment and methods, in particular to a sludge drying and incineration integrated equipment and a sludge incineration method. Background technique [0002] With the rapid economic development, the amount of urban sewage has gradually increased, and the construction scale of municipal sewage treatment plants has also continued to expand, resulting in an increasing output of residual sludge after sewage treatment. At present, sludge disposal technologies can be divided into incineration, landfill, and land use. Sludge incineration is recognized as one of the most practical treatment technologies due to its advantages of high reduction degree, on-site incineration, no need for long-distance transportation, and resource utilization of fly ash. [0003] According to the requirements of the "Technical Specifications for Sludge Incineration Treatment Engineering in Urban Sewage Treatment P...
