Smelting furnace

Abstract

The invention relates to a smelting furnace. The smelting furnace comprises a furnace body, a double-layer smoke collecting bin, a smoke exhausting pipe and an electrostatic generator, wherein the front end of the smoke exhausting pipe is communicated with an inner bin of the double-layer smoke collecting bin, the inner bin of the double-layer smoke collecting bin is communicated with the furnace body, the middle part of the smoke exhausting pipe is in an up-down return state, two bending parts are arranged at the lower end of the middle part in the up and down state of the smoke exhausting pipe, and one dust removing tank is arranged at the lower end of each of the two bending parts and communicated with the corresponding bending part; one filtering net is arranged at the inner part of each of the two bending parts and on the rear side of the upper end of each of the dust removing tanks, the electrostatic generator is electrically connected with the two filtering nets respectively, an outer bin of the smoke collecting bin is also communicated with a water pump through a pipeline, and a water outlet is formed in the smoke collecting bin. The smelting furnace disclosed by the invention is good in dust removing effect and convenient for depositing and removing smoke dust and recycling heat energy.

Description

technical field [0001] The invention relates to the technical field of smelting, in particular to a smelting furnace. Background technique [0002] Currently used smelting furnaces, some use a chimney to discharge waste gas vertically upwards, and some use a smoke exhaust pipe to first upward, then obliquely downward, and upward exhaust again, all of which have the disadvantages of incomplete dust removal and polluted air; prior art Among them, "A Smelting Furnace" with application number 201320467666.9 has the following defects: 1. The dust removal effect is not complete, and dust is easy to accumulate in the exhaust pipe, which reduces the smoke exhaust efficiency of the exhaust pipe and is easy to block the exhaust pipe; 2. 1. There is also a lot of dust mixed in the exhaust gas, which seriously affects the ecological environment. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a smelting furnace with good du...
