Tank shell type liquid level adjusting device for desulfurizing tower

Abstract

The invention relates to a tank shell type liquid level adjusting device for a desulfurizing tower. The tank shell type liquid level adjusting device for the desulfurizing tower comprises the desulfurizing tower, wherein a semi-circular barrel which communicates with the desulfurizing tower is arranged below one side of the desulfurizing tower; a sleeve which communicates with the semi-circular barrel is vertically arranged on the top of the semi-circular barrel; a drainage groove is formed in the upper part of the semi-circular barrel; a top extension section of the sleeve is arranged in the drainage groove; a positioning plate is transversely placed on the drainage groove; a nut is arranged on the positioning plate and is connected with a lead screw; a hand wheel is arranged at the upper end of the lead screw; and a cylinder is arranged at the lower end of the lead screw, is inserted in the sleeve and can move in the up-down direction. The tank shell type liquid level adjusting device for the desulfurizing tower is simple in structure and stable in operation; while stable running of the desulfurizing tower is guaranteed, later maintenance of equipment is facilitated; and the economic benefit is remarkable.

Description

technical field [0001] The invention relates to an industrial waste gas treatment device, in particular to a desulfurization tower tank tank type liquid level adjustment device. Background technique [0002] Boiler flue gas double-alkali desulfurization is the most suitable desulfurization process for small industrial boilers, especially the dust removal and desulfurization integrated device, which can carry out dust removal and desulfurization at the same time, and can improve the dust removal efficiency. In the double-alkali desulfurization process, the desulfurization tower is the most important equipment. The working principle is: the prepared sodium hydroxide or sodium carbonate solution is used as the starting desulfurization agent, and pumped into the desulfurization tower to wash and remove SO2 in the flue gas to achieve flue gas. The purpose of gas desulfurization, and then the desulfurization product is regenerated into sodium sulfite or sodium hydroxide through th...

Problems solved by technology

The working principle of the invention is the principle of a connecting device. During operation, the operator adjusts the vertical displacement of the cylinder through the hand wheel to realize precise control of the liquid level in the desulfurization tower, and then establishes a pressure balance between the desulfurization tower and the liquid outlet to realize automatic separation of gas and liquid. ;The sleeve provided can significantly increase the contact surface with the cylinder, play a sealing and guiding role, and can effectively overcome the problem of poor sealing and easy seepage of the contact between the cylinder and the half-drum, and at the same time ensure that the cylinder Stability of up and down displacement
