Efficient heater for coal-fired spray drying tower

Abstract

The invention relates to an efficient heater for a coal-fired spray drying tower. The heater comprises a hearth, a flue, a sand cleaning hole and a smoke outlet, wherein the flue is formed by arranging a plurality of primary burning flame paths and a plurality of secondary burning flame paths at intervals and connecting the flame paths in an end-to-end mode; upper fire baffle walls are convexly formed on the inner surfaces of the top walls of the primary burning flame paths and the secondary burning flame paths; lower flame baffle walls are convexly formed on the inner surfaces of the bottom walls of the primary burning flame paths and the secondary burning flame paths; and the upper flame baffle walls and the lower flame baffle walls are arranged at intervals. By arranging the upper flame baffle walls and the lower flame baffle walls, the flue of the heater becomes narrower and longer, and the burning space of coal is increased, so that micro coal dust has enough space and time to be repeatedly burned in smoke flow, and heat efficiency and a burn-off rate are improved; and most of the coal dust in the smoke flow is stopped and removed by the upper and lower flame baffle walls during wavy movement, so that the coal dust quantity of the smoke is greatly reduced, and the aims of high fixation possibility of carbon and sulfur and environment friendliness are fulfilled.

Description

Technical field [0001] The invention relates to a spray drying tower heater, in particular to a high-efficiency coal-fired spray drying tower heater for ceramic production. Background technique [0002] Ceramic spray drying tower is the key equipment for wet powder making in the production process of building ceramic wall and floor tiles. Since the successful research and development of spray tower drying technology in the 1980s, it has been widely used in the production process of building ceramic wall and floor tiles. The spray drying tower produces wall and floor tile forming granular powder, which is still the most ideal forming powder for large-scale automatic presses. . With the further development of wall and floor tile production equipment and technology, the spray drying tower has been further developed to large-scale to adapt to the expanding production scale. We know that the production of building ceramic wall and floor tiles is a high energy consumption industry. T...

AI Technical Summary

Problems solved by technology

We know that the production of architectural ceramic wall and floor tiles is a high-energy-consuming industry, and the spray drying tower is a high-energy-consuming link in the production process of wall and floor tiles. As a part of the spray drying tower, the existing spray drying tower heaters often have high combustion energy consumption and low thermal efficiency. Low, insufficient combustion, a large amount of coal dust in the flue gas pollutes the environment, etc.
