The invention discloses a slide valve special for an adsorption desulfurization device. The slide valve comprises a valve body, a bonnet connected with the valve body through a connecting assembly, and a valve rod used in cooperation with the bonnet. The valve body comprises an intermediate valve body and two side end flanges in fit connection with the intermediate valve body. A guide sleeve is arranged in the bonnet. The valve rod is arranged in the guide sleeve. A sliding plate is arranged at the lower end of the valve rod. A valve seat and a guide frame are arranged in the intermediate valve body. The valve seat is arranged at the position of an inlet flow channel of the intermediate valve body. The guide frame is arranged at the position, corresponding to the valve rod, of the intermediate valve body. The sliding plate is driven by the valve rod to relatively slide in the axial direction of the valve rod in the guide frame. The valve seat, the sliding plate and the guide frame areall made of monolithic sintering hard alloy materials. The inner wall of an inlet flow channel and the inner wall of an outlet flow channel of the valve body are coated with hard alloy in a spraying manner. According to the slide valve special for the adsorption desulfurization device, the service life of the valve can be greatly prolonged, and the repair and maintenance cost of a user is reduced.
Description
technical field [0001] The invention relates to the field of petrochemical industry, mainly aims at the adsorption desulfurization technology of gasoline fraction, and in particular relates to a slide valve specially used for an adsorption desulfurization device. Background technique [0002] In recent years, with people's increasing emphasis on environmental protection, my country's motor gasoline standards have been continuously upgraded, and the sulfur content in motor gasoline has gradually decreased. At this stage, it is required to produce low-sulfur clean gasoline products with a sulfur content below 10ppm. The S-Zorb process is a gasoline adsorption desulfurization technology introduced by Sinopec. This technology has the characteristics of high desulfurization depth and little impact on the octane number of the product. It is very suitable for the current situation that domestic gasoline products mainly come from catalytic cracking, and has become the first choice fo...
