Desulfurizer anti-deposition method for industrial furnace

Abstract

The invention relates to the technical field of waste gas desulfurization, and discloses a desulfurizer anti-deposition method for an industrial furnace. The desulfurizer anti-deposition method for the industrial furnace comprises a slurry tank, wherein the top end of the slurry tank is fixedly connected with a stirring group, one side of the top end of the slurry tank is provided with a discharging port, the other side of the top end of the slurry tank is fixedly connected with a pressure valve, and one side of the slurry tank is fixedly connected with a one-way slurry outlet valve; one side of the one-way slurry outlet valve is fixedly connected with an air chamber, the front top end of the air chamber is fixedly connected with a one-way air valve, and the front bottom end of the air chamber is fixedly connected with a one-way slurry inlet valve. A piston in the air chamber moves towards the back through negative pressure of the air chamber on the back in the air chamber, and the bottom end of the front of the air chamber sucks slurry through the one-way slurry inlet valve and meanwhile sucks a movable block to move towards the other side in a slurry pipeline, so that the desulfurizer slurry in the slurry pipeline is recycled, waste of the desulfurizer slurry due to shutdown is avoided, restirring is facilitated after recycling, and the situation that the recycled desulfurizer slurry is layered and deposited and cannot be continuously introduced for use is avoided.

Description

technical field [0001] The invention relates to the technical field of exhaust gas desulfurization, in particular to an anti-deposition method for desulfurizers in industrial furnaces and kilns. Background technique [0002] In the production of industrial furnaces, in order to make the treated waste gas meet the discharge standard, desulfurization towers are usually used to desulfurize the waste gas and a series of treatments to make the gas harmless. The desulfurization process includes dry desulfurization and wet desulfurization. In the wet desulfurization process, there are lime method, sodium-calcium double alkali method, magnesium oxide method, and limestone method. In the wet desulfurization process, a slurry tank is usually used to prepare desulfurizer slurry for process water and desulfurizer. In the process from the slurry tank to the desulfurization tower, the desulfurizer slurry is introduced through the slurry pipeline, and the switch of the slurry pipeline is c...
