Embodiment Construction
[0015] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:
[0016] See figure 1 , is a schematic structural diagram of an embodiment of a plug-in preheating device according to the present invention. The heat exchange tubes 3 are vertically arranged on the inner side wall of the kiln channel 11, and the inlet end of the heat exchange tube 3 passes through the refractory masonry of the channel side wall and the The air inlet air collection bag 1 is connected, and the outlet end of the heat exchange tube 3 is connected to the air outlet air collection bag 2 through the pouring material at the top of the channel. The masonry structure of the kiln channel is used as the outer shell of the heat exchanger. The heat exchange tube is inserted from the outside of the channel into the channel to absorb the high-temperature radiation and convective heat transfer of the gas in the channel. Enter the intake gas collec...

The invention relates to the field of industrial kiln stoves with straight channels and particularly to a plug-in type preheating device. The device comprises a heat exchange pipe and is characterized in that the heat exchange pipe is arranged on the inner side wall of a channel of a kiln stove body vertically, a gas inlet end of the heat exchange pipe penetrates through a fire-resistant masonry on the side wall of the channel and is connected with a gas inlet and collection bag, and a gas outlet end of the heat exchange pipe penetrates through a casting material at the top of the channel and is connected with a gas outlet and collection bag. Silicon carbide tubing bricks are arranged on the outer side of a section of the heat exchange pipe, which is located inside the channel. A fire-resistant fiber mat is arranged between the heat exchange pipe and the casting material of the channel. A differential pressure transmitter is arranged between the gas inlet and collection bag and the gas outlet and collection bag. Compared with the prior art, the plug-in type preheating device has the advantages that 1), a kiln-stove channel structure is used effectively, a preheating structure is simple and compact, and the occupied space is small; 2), high-temperature radiation and convective heat exchange of high-temperature flue gas in the channel are used efficiently, so that coal gas or air is preheated; and 3), flow can be regulated according to the temperature in real time.
Description
technical field [0001] The invention relates to the field of industrial furnaces with straight passages, in particular to a plug-in preheating device. Background technique [0002] At present, in order to reduce heat consumption and increase kiln temperature, most domestic kilns use preheating devices to preheat gas or combustion air. Most of the preheating devices use metal shell and tube heat exchangers, and use the exhaust gas from the kiln as the heat medium. However, for some kilns, such as soaking furnaces, double-chamber kilns, etc., the exhaust gas temperature in the passage is very high, and it is difficult to use traditional metal heat exchangers. Contents of the invention [0003] The purpose of the present invention is to provide a plug-in preheating device, which overcomes the deficiencies of the prior art, utilizes the structural characteristics of the kiln itself, integrates the heat exchange structure and the kiln body structure, and achieves the double ef...
