Embodiment Construction

[0016] The present invention will be further described below according to the accompanying drawings and in conjunction with the embodiments.

[0017] attached figure 1 The shown integrated arsenic collector includes a rectangular housing 5 with a relatively independent and connected diversion distribution area 1 , a temperature control area 2 , a purification area 3 , a pulse injection assembly 4 and an arsenic collection barrel 6 . The diversion distribution area 1 is in figure 1 The front part of the upper section of the shown housing 5 has a main body that is a recumbent square tube. The left end of the tube is open and the right end is closed. The downward facing tube wall is provided with a set of through holes corresponding to the heat exchange tube 2.2. The arsenic trioxide-containing gas discharged from the front electrostatic precipitator is introduced into the device from the opening at the left end. The temperature control area 2 is located under the diversion dis...

Abstract

The invention discloses an integrated arsenic collector, which comprises a flow guide distribution area, a temperature control area, a purification area, a pulse blowing component and an arsenic collecting barrel which are arranged in a shell. The flow guide distribution area positioned in the front part of the upper section of the shell is connected with the temperature control area below through a heat exchange tube; the temperature control area is divided by a horizontal partition board into upper and lower two parts; and the upper part is a temperature reduction area and the lower part of a temperature rise area. The purification area is positioned at the rear part of the shell and is parallelly separated from the flow guide distribution area and the temperature control area. The inside of the purification area is provided with a cloth bag of which the opening is connected with a gas collecting tube. The arsenic collecting barrel is positioned at the bottom of the shell to collect powdered arsenic trioxide falling from the cloth bag. The integrated arsenic collector has small temperature control space, large heat exchange area and high efficiency, is easy to product a shock chilling condition and allows the powdered arsenic trioxide to be filtered out by the cloth bag and collected in the arsenic collecting barrel.

Description

technical field [0001] The invention relates to a dust collection device. Specifically, the invention relates to a device for collecting powdered arsenic from smoke generated by refining gold, which belongs to the technical field of environmental protection. Background technique [0002] In nature, most gold concentrates are associated with arsenic, which is an important chemical raw material. Its physical characteristics are that its melting point is much lower than that of gold and it is easy to oxidize. When gold is extracted from gold concentrate, the contained arsenic is oxidized by heating to form arsenic trioxide gas, and the overflowing high-temperature arsenic trioxide gas crystallizes to form powdery arsenic trioxide after a sudden drop in temperature. Arsenic trioxide, commonly known as "arsenic", is a well-known highly toxic substance and is strictly regulated by the state. For the arsenic trioxide gas produced by the gold smelting industry, the state explicitly...
