Energy-saving type shuttle type kiln

Abstract

The invention discloses an energy-saving type shuttle type kiln. The energy-saving type shuttle type kiln comprises a furnace body, at least one pair of heat-accumulating type combustors, a heat exchanger, corresponding valves, pipelines and a fan, wherein the combustors are arranged on the furnace body and are connected with the fan and a gas pipeline by the pipelines and the valves. When one of the combustors is in a combusting state, the other one is in a smoke-exhausting state, and the smoke stores heat in a heat-accumulating material in the combustors, and then is exhausted out of the system. When the preset time is up, the valves of the two combustors are switched, the combustor in the smoke-exhausting state is changed to be in the combusting state, and air absorbs the heat stored in the heat-accumulating material when passing through the combustor and carries the heat into a furnace so as to realize heat recovery. When a plurality of pairs of combustors are arranged, the working state of each combustor is opposite to that of the peripheral combustors so as to realize cross combustion. In the cooling process, heating and water supply are performed on the hot air by the heat exchanger on a spare flue, and the heat is absorbed by water so as to be utilized. The energy-saving type shuttle type kiln has the advantages that not only is the energy-saving effect obvious, but also the temperature distribution in the hearth is uniform, the temperature rising speed is high and the combustion temperature is high.

Description

technical field [0001] The invention relates to a shuttle kiln, in particular to a high-efficiency and energy-saving shuttle kiln. Background technique [0002] The shuttle kiln is a kiln for intermittent firing. It is similar to the structure of a matchbox. The kiln car is pushed into the kiln for firing, and then pulled out in the opposite direction to unload the fired ceramics. The kiln car is like a shuttle, so it is called Shuttle kiln, also known as drawer kiln. The shuttle kiln is suitable for drying, heating and firing of multi-variety and small batches of daily-use ceramics, sanitary ceramics, electronic ceramics, refractory materials and chemical powder materials. [0003] The heat utilization rate of the traditional shuttle kiln is only about 20%, and most of the heat is wasted in the process of flue gas discharge, heat storage and heat dissipation of the kiln body. The temperature inside the shuttle kiln, that is, the exhaust gas temperature at the furnace outl...

AI Technical Summary

Problems solved by technology

However, there are still unavoidable problems of flame upward and deflection toward the smoke exhaust port, which makes the burned products have color difference and other quality problems.
