Abstract:
A screw pressing type filtering apparatus that discharges a treated substance having a constant water content, including a screw rotatably provided inside a substantially cylindrical filter body so that a substance supplied to the space between the screw and the filter body is filtered by the filter body while being conveyed by the rotating screw. The apparatus further includes: a back pressure valve installed in the discharge port of the filter body to restrict the discharge amount of the filtered substance, an air cylinder that supplies a pressure to the back pressure valve, a valve opening detector which detects the opening amount of the back pressure valve relative to the discharge port, and a control section which controls the air cylinder based upon the detection results of the valve opening detector so that a pressure that corresponds to the degree of opening is supplied to the back pressure valve.
Abstract:
An improved process for desulfurization of waste gas emitted from, for example, various boilers. Five steps, namely, (1) the step of absorption of waste gas, (2) the step of pyrolysis, (3) the step of recovery and recycle of products, (4) the step of recovery of sulfur and (5) the step of recycle of by-products formed in the step (4), are included. As a further preferred embodiment, excesssive fuels are supplied in the step of pyrolysis (2) to generate a mixed gas, which is subjected to desulfurization in the step of removal of sulfur (4) and then utilized for heating the wet desulfurized gas coming out of the step of absorption (1). This process represents an improvement over the conventional process particularly in respect of the loss of alkali metals which can be minimized because they are recycled in the process.
