Multi-Dish Acid Distributor

Categories: Equipment for sulfuric acid industry

The dish acid distributor is an invention patent and the abbreviated term for a multi-dish liquid distributor used in sulfuric acid plants. This technology finds wide application in flue gas purification systems for coal-fired power plants and large-scale chemical facilities including oil refineries, petrochemical plants, and fertilizer factories.

Scaling effects in large packed towers primarily result from uneven flow distribution points. In contrast, the multi-dish liquid distributor prevents this issue, ensuring uniform liquid distribution.

Product Description

Dish acid distributor is consisted of six parts including feed header, feed branch, distributing pipe, orifice plate, distributing dish, downcomer. Distributing dishes are cylinder type while the distributing section is in square except dishes on the periphery of tower. The dish and square section are concentric. In general, in each dish there are 16 or 30 pieces of downcomers, which form square or triangle on packing surface. For example, 16 pieces of downcomers are 4×4 arranged, namely square arrangement (exactly right triangle arrangement); 30 pieces of downcomers are 5×6 arranged, namely isosceles triangle arrangement with 62°vertex angle. These downcomers from dishes bottom extending to downcoming point can carry acid to packing surface. Each dish connects to one distributing pipe, which connects to feed branch or header. After flowing out from distributing pipe located at dish center, acid then radially flows to downcomers. And quantity of dishes depends on tower diameter and density of distributing point.

Applications:

It can be widely used in tail gas purification for coal-fired power plant and large-scale chemical plant of oil refining, petrochemical and fertilizer.

Competitive Advantage:

Distributing evenness, wide range of adjusting flow, light weight, no scaling effect, and easy installation and maintenance
