Energy-saving environment-friendly circular cooler

Abstract

The invention relates to cooling equipment in a metallurgy sintering system, in particular to an energy-saving environment-friendly circular cooler, which comprises a framework. Trolleys are arranged in a frame, trolley baffle plates are mounted above the trolleys, the frame is connected with bellows and is a circular rotator structure, the frame and the bellows are provided with sliding sealing rings, sealing covers are connected to upper sides of the trolley baffle plates, heat-insulation bodies are respectively sleeved on outer portions of the sealing covers and the trolley baffle plates, the circular rotator frame is divided into high-temperature waste heat recycling areas and low-temperature cooling areas, a sectioning partition is mounted between sealing rings of each high-temperature waste heat recycling area and the correspondingly adjacent low-temperature cooling area, and an air valve is mounted between the bellows of each high-temperature waste heat recycling area and the correspondingly adjacent low-temperature cooling area. The heat-insulation bodies are respectively sleeved on the outer portions of the trolley baffle plates and the sealing covers, the sliding sealing rings are disposed between the frame and the bellows, and cooling air which is delivered to materials of the trolleys by the bellows cannot leak assuredly; and cooling efficiency can be improved by 40% at least, and a large quantity of electric energy can be saved.

Description

Technical field: [0001] The invention relates to cooling equipment in a metallurgical sintering system, in particular to an energy-saving and environment-friendly ring cooler. Background technique: [0002] The ring cooler is the main cooling equipment in the metallurgical sintering system and has been widely used. However, with the advancement of science and technology, the country's requirements for environmental protection are increasing, and energy saving and consumption reduction are the main ways for enterprises to reduce product costs. However, due to the high air leakage rate of 50-60% in the blast ring cooler used in the traditional sintering system, the efficiency of the air supply system is low, the power consumption is large, and a large amount of sintering dust is brought out by the air leakage, causing environmental pollution. The high air leakage rate makes the waste heat of the annular cooler unable to be effectively recovered. Moreover, the traditional annu...
