Combined body of composite type rotating sludge incineration kiln and reciprocating type sludge incineration kiln

Abstract

The invention discloses a combined body of a composite type rotating sludge incineration kiln and a reciprocating type sludge incineration kiln. A reverse interaction heat exchange mode is adopted for the moving direction of sludge materials of the composite type rotating sludge incineration kiln and the flow direction of high-temperature flue gas of a heat source, and the heat exchange ability is high; the inner wall of a cylinder is provided with a lifting plate which can lift the sludge materials to the portion above the inner side of the kiln cylinder, N times of curtains of the N sludge materials are formed in the cylinder of the rotating kiln, and the time for heat exchange of full contact of the high-temperature flue gas and the sludge materials is longer; meanwhile, the lifting plate absorbs heat of the high-temperature flue gas and transmits the heat to the sludge materials, and therefore the sludge dewatering and drying effect is better. According to the heat resource of the composite type rotating sludge incineration kiln in the structure of the combined body, the unburned sludge materials left by incineration in the composite type rotating sludge incineration kiln in the former working procedure continue to be incinerated in the reciprocating type sludge incineration kiln for providing all heat energy, a fuel oil and gas burner does not need to be used as an auxiliary heat source, and the operation cost is lower.

Description

technical field [0001] The invention relates to a water-based sludge treatment equipment, in particular to a combination of a compound rotary sludge incineration kiln and a reciprocating sludge incineration kiln. Background technique [0002] Oil drilling water-based sludge is a waste mud with almost no calorific value separated by vibrating screens, which contains natural soluble salts, heavy metals, suspended solids, polyacrylamide, sulfonated asphalt, solid particles, Hydrogen sulfide, microorganisms, colloids, bacteria, germs, cysts, toxic and harmful pollutants, etc., as well as chemical additives such as acids, oxygen scavengers, lubricants, bactericides, and scale inhibitors injected into the formation. At present, the methods for sludge treatment mainly include biodegradation sludge treatment method, chemical agent acid-base neutralization treatment method, sludge solidification sludge treatment method, sludge drying treatment method and sludge incineration treatment...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the above technical problems, the present invention proposes a combination of a composite rotary sludge incineration kiln and a reciprocating sludge incineration kiln. The combination has a simple structure, timely and efficient treatment, and low operating costs; Mud, toxic and harmful substances do not fall to the ground; avoid the problem of large-scale environmental pollution caused by sewage sludge scattered everywhere in the process of automobile transportation in the centralized treatment method currently on the market; it can be achieved that the vehicle does not exceed the length x width x height, Overweight, small footprint, stable and reliable, reasonable power, safe and environmentally friendly; and the complete set of equipment can be moved and relocated at any time, which is in line with the characteristics of large mobility in field operations
