Waste liquid combustion furnace

Abstract

The invention discloses a waste liquid combustion furnace. The waste liquid combustion furnace comprises a furnace body, a refractory layer arranged around the furnace body, and a spraying gun arranged at the end part of the furnace body; a primary air inlet, a secondary air inlet, an ignition port and a gas inlet are arranged in the furnace body in a communication manner; a coil is arranged in the refractory layer; the two ends of the coil are exposed at the external of the furnace body; the end part of each end is connected with a threading joint; a threading joint is arranged at the end part of the spraying gun; and the threading joint at the end part of the spraying gun and the threading joint at one end of the coil are connected through a pipeline. The waste liquid combustion furnacehas the following advantages: the operation cost is saved by above 30%; the treatment effect is excellent, and is improved by above 20% compared with general incineration efficiency; the treatment isconvenient; and as incineration is more thorough, harmful substances in smoke are totally combusted and decomposed, and tail gas is treated easily.

Description

technical field [0001] The invention specifically relates to a waste liquid combustion furnace. Background technique [0002] At present, domestic general combustion furnaces for treating waste liquid adopt the style before the fire and after the liquid, that is, the method of spraying the fire in the front and spraying the liquid in the back. , The combustion in the combustion furnace is not sufficient, resulting in low combustion efficiency, and due to insufficient combustion, the content of harmful substances in the flue gas is high, and the treatment of the tail gas increases the cost. Contents of the invention [0003] In view of the above technical problems, the present invention provides a waste liquid combustion furnace. [0004] A waste liquid combustion furnace, comprising a furnace body, a refractory layer arranged around the furnace body, and a spray gun arranged at the end of the furnace body, connected to the inside of the furnace body and provided with a ...
