Small pit type furnace with tail gas recycling device

Abstract

The invention discloses a small pit type furnace with a tail gas recycling device in the technical field of pit type furnaces. A waste gas box is arranged on the right side of the bottom of a furnacebody inner cavity; an exhaust pipe is arranged at the bottom of the right side of the waste gas box; a first control valve is arranged on the right side of the exhaust pipe; a double-layer pipe is arranged on the right side of the furnace body; the double-layer pipe comprises an inner pipe and an outer pipe; an air inlet is formed in the bottom of the inner pipe; an air outlet is formed in the topof the inner pipe; the air inlet is connected with the exhaust pipe; an air outlet pipe is arranged at the bottom of the right side of the outer pipe; a one-way valve is arranged in the air outlet pipe; a ventilation pipe is arranged on the right sides of the tops of the gas outlet pipe and the furnace body; a heating device is arranged at the bottom of the right side of the ventilation pipe, a discharging pipe is arranged at the top of the ventilation pipe, a quantitative air outlet device is arranged in the discharging pipe, a second control valve is arranged at the top of the ventilation pipe, and the second control valve is located on the left side of the discharging pipe. The device is simple in structure and high in recycling rate.

Description

technical field [0001] The invention relates to the technical field of well-type furnaces, in particular to a small-sized well-type furnace with a tail gas recycling device. Background technique [0002] The well-type furnace will generate a large amount of combustible waste gas when it is working. These combustible waste gases can be recycled. At present, there are devices for recycling these tail gases on the market, but the recycling effect is not ideal, and the structure is complicated and the cost is high. , for this reason, we propose a kind of small well-type furnace with tail gas recycling device. Contents of the invention [0003] The object of the present invention is to provide a small well-type furnace with a tail gas recovery and utilization device to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention provides the following technical solutions: a small pit-type furnace w...
