A device for clean production of tungsten disulfide

Abstract

The invention discloses a device for clean production of tungsten disulfide. The device comprises a box-type reaction tube and a sulfur recycling tower, wherein the box-type reaction tube is divided into a feeding area, a reaction area, a low-temperature area, a cooling area and a discharging area; a pusher track is arranged in the box-type reaction tube, pushers are arranged on the track, an inert gas inlet is formed in the upper part of the feeding area, a feeding opening is formed in the side part, and the head part of the feeding area is provided with an electric push rod device; a high temperature area is heated and thermally controlled by virtue of a resistance furnace, a gas outlet is formed in the top of the reaction area on the lower end of gas flow, and the reaction area is connected with a sulfur recovering tower by virtue of a resistance wire insulation pipe; one side of a sulfur outlet in the bottom of the low-temperature area is provided with a slope of 5 to 15 degrees, the surface of the slope is coated with tungsten disulfide of 0.05mm to 10mm, a sulfur outlet in the bottom end of the slope is connected with the sulfur recovering tower, and a connection part is thermally insulated by virtue of asbestos; the cooling area is coated with a cooling water layer to lower the temperature. By adopting the device, the sulfur interception can be avoided, continuity in clean production can be realized, no waste gas, waste water and industrial residue is produced, the device is environment-friendly and pollution-free, and the continuous industrialized mass production can be realized.

Description

technical field [0001] The invention relates to a device for producing tungsten disulfide, in particular to a device for clean production of tungsten disulfide. Background technique [0002] The friction coefficient of tungsten disulfide is only 0.03, the working temperature is -270℃~650℃, and the extreme pressure capacity reaches 2000Mpa. Can be used as a lubricant, performance is better than molybdenum disulfide. It can be used alone for equipment operating at high temperature, high pressure, high speed, high load, and in chemically active media. Forging and stamping lubricants can also be configured with other materials, which can prolong the life of the die and improve the smoothness of the product. It can be used to make self-lubricating parts by configuring filling materials such as PTFE and nylon. In addition, tungsten disulfide can also be used as a catalyst in the petrochemical industry. Its advantages are high cracking performance, stable and reliable catalytic ...
