Embodiment Construction

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0020] As shown in Figures 1 and 2, a low-temperature coal dry distillation square furnace includes a furnace body 27, a coal hopper 29, a coke pusher 39, and a branch pipe mixer 38, wherein a gas-collecting array umbrella 37 is installed on the top of the furnace chamber 28 The air-collecting array umbrella 37 comprises a main umbrella 10, an auxiliary umbrella 14, and a rising pipe 16, and there are 10 auxiliary umbrellas 14, which are symmetrically connected to both sides of the main umbrella 10. The parachute channel 15 is convenient to collect the raw gas collected by the parachute 14 into the main parachute 10; the top of the main parachute 10 is communicated with two ascending pipes 16, and the ascending pipes 16 extend out of the furnace cavity and are connected with the bridge ...

Abstract

The invention disclosed a kind of low temperature coal dry distillating square stove which includes stove body, coal cup, dant-pushing machine and branch admixer. On the top of the hearth there is installed the gas collecting umbrella, inside the stove it is cavity structure; on the bottom of the cavity there are installed several rows of emitting gas walls, every row of emitting gas wall is parallel to the interval between two side umbrella of the gas collecting umbrella; the consecutive emitting gas walls are pedestalled by arch wall; on both sides of the emitting gas walls there are two branch admixer respectively; the bottom of the stove connects the dant discharging box, the bottom of which connects the dant leading slot; the bottom of the dant leading slot is dant-pushing machine, the bottom of which is aqua sealing slot, in the slot there is scraper machine. The invention adopts the heating scheme of endo-burnning and calor internus which can heat uniformly. The gas collecting umbrella and accessory coalbox can make the material and gas-collecting uniformly while the dant-pushing machine can make the product uniform. The advantage of the invention: it can bring into full play of the producing ability and decrease the investment as well as increase the benefits; besides, it is easy to operate, it needs less people and can be controlled automatically.

Description

technical field [0001] The invention relates to a dry distillation furnace, in particular to a coal low-temperature dry distillation square furnace. Background technique [0002] The original carbonization furnace is a vertical cavity with the same width, and a heating combustion chamber is arranged on both sides of the vertical cavity, and the heating gas is injected into the vertical cavity after being burned at a high temperature in the combustion chamber. The existing problem is: the high temperature gas enters the furnace, the temperature is not easy to control, it is easy to cause the coal to ash and hang slag due to the high temperature, which affects the service life of the furnace, and affects the output and quality of the product. Moreover, the volume of the vertical cavity is small, and the output is also very low. Contents of the invention [0003] In order to solve the above-mentioned existing problems, the object of the present invention is to provide a low-...
