Spray drying device utilizing waste heat of kiln and ceramic production line

Abstract

The invention discloses a spray drying device utilizing waste heat of a kiln, which comprises a spray drying tower, a hot air furnace and a waste heat pipe, wherein the spray drying tower is connected with the hot air furnace through a connecting pipeline; and the waste heat pipe is arranged on the connecting pipeline. The spray drying device utilizing the waste heat of the kiln can effectively utilize the waste heat of the kiln, and can solve the problem of the uniformity of hot air temperature in the spray drying tower. Based on the spray drying device, the invention also provides a ceramic production line, which comprises a press machine workshop, a kiln feeding machine, the kiln, and the spray drying device utilizing the waste heat of the kiln, wherein the press machine workshop, the kiln feeding machine, the kiln, and the spray drying device utilizing the waste heat of the kiln are orderly connected. The ceramic production line can reduce the transportation power of the waste heat of the kiln, and can effectively avoid the loss of the heat of the waste heat of the kiln.

Description

technical field [0001] The invention relates to the field where a heating method is required to dry solid materials or products, and specifically refers to a spray drying device and a ceramic production line utilizing waste heat from a kiln. Background technique [0002] At present, most ceramic factories use powder to manufacture. The spray drying tower is provided with hot air as a heat source by a hot blast stove. The higher the temperature, the higher the thermal efficiency. The hot air enters from the top of the tower; the mud (with a moisture content of about 30%) is atomized into droplets (about 300 μm in diameter) through the nozzle atomizer, and the droplets The smaller it is, the larger its total evaporation surface area is, and the faster the drying speed is, the nozzle is installed at the middle bottom of the tower body. The mist and the hot air first move upwards in countercurrent, and then move downward together with the hot air after reaching a certain height...

AI Technical Summary

Problems solved by technology

However, the existing structure of the spray drying tower has not been improved, and the waste heat and the hot air from the hot blast stove are mixed unevenly, which makes the temperature of the hot air input into the spray drying tower The uniformity is not high, which affects the quality of the material

[0004] At present, the ceramic production line using waste heat is generally connected from the kiln at the end of the production line to the spray drying tower hot air stove at the head of the production line. Due to the long pipeline, it not only increases the transportation power of the waste heat of the kiln, but also easily causes unnecessary loss of waste heat. As a result, the effect of waste heat utilization is not good
