Acetylene gas generator taking calcium carbide dust as raw material

Abstract

The invention relates to the technical field of crushing and dust treatment of calcium carbide and in particular relates to an acetylene gas generator taking calcium carbide dust as a raw material. The acetylene gas generator is formed through welding and connecting a barrel body, an upper end socket and a lower tapered shell, wherein the barrel body is internally provided with a stirring device and a baffle; the upper end socket is provided with a slag slurry circulating pipe connector, a calcium carbide dust inlet, an acetylene gas outlet, a nitrogen gas inlet, an exhausting hole, an explosion-proof hole, a teletransmission pressure gauge hole, a field pressure gauge hole, a pipe-connection short pipe and a flange; a lug type support and a support base plate are fixed on the outer wall of the barrel body and a manhole is further formed in the outer wall of the barrel body; a field liquid level meter hole, a field liquid level meter hole, a teletransmission liquid level meter hole, another teletransmission liquid level meter hole, a teletransmission thermometer hole and a field thermometer hole are further formed in the outer wall of the barrel body; the section of the lower tapered shell is an oblique triangle; a stirring shaft of the stirring device stretches into the barrel body through a central hole in a long oblique edge at the bottom of the lower tapered shell; a slag slurry outlet is formed in a short oblique edge of the lower tapered shell. By adopting the acetylene gas generator, environment protection is facilitated. The utilization rate of a chemical raw material, namely the calcium carbide, is effectively improved.

Description

technical field [0001] The invention relates to the technical field of calcium carbide crushing ash treatment, in particular to a [0002] Acetylene gas generator as raw material. Background technique [0003] Calcium carbide powder produced during the crushing process of calcium carbide is a fine dust particle of calcium carbide. In the production plant, the polluted air and the ground are full of dust, which drifts and spreads with the wind, polluting the atmosphere and the surrounding environment. [0004] Existing commonly used methods for processing calcium carbide powder produced by crushing calcium carbide are: regular cleaning every day, garbage transfer, centralized dragging away, landfill treatment, and natural settlement. The above-mentioned processing methods for calcium carbide slag all have the following defects: [0005] Landfill treatment: Carbide slag is directly discharged into seawalls and valleys, or piled up regularly. Carbide slag is hardly treated, c...

Problems solved by technology

[0005] Landfill treatment: Carbide slag is directly discharged into seawalls and valleys, or piled up regularly. Carbide slag is hardly treated at all, causing serious pollution and occupying a large area of ​​land

[0006] Sell ​​after natural settlement: Discharge the calcium carbide slurry into the sedimentation tank or a low-sunken open space, evaporate naturally and wait for the slurry to settle, then excavate it manually, forklift or grab for sale, this method is very vulnerable to the environment and weather Influenced by conditions, especially in the south, the amount of rainfall is large, the evaporation is small, and the water content of the sediment in the rainy season is high, generally 50% to 60% in the form of thick slurry, which cannot be excavated and utilized at all.
