Problems solved by technology

[0004] It can be seen that the above two documents both adopt the technical scheme of collecting the slurry flow, but this scheme cannot solve the problem of insufficient absorption of the flue gas when it passes through the spray dilute phase zone

Embodiment Construction

[0024] The present invention is described in detail below in conjunction with embodiment.

[0025] combine first figure 1 The operation of the spray tower adopting the preferred embodiment of the present invention will be described. During operation, the flue gas enters the spray tower through the entrance 1 of the spray tower, climbs up and passes through the first layer of gas gathering ring 4, the first layer of spray layer 8, the second layer of gas gathering ring 5, and the second layer of spraying Layer 9, the third gas-gathering ring 6, the third spray layer 10, the fourth gas-gathering ring 7, the fourth spray layer 11, the demister layer 12, and flow out from the outlet 3 of the spray tower. Those of ordinary skill in the art can understand that the number of spray layers and corresponding gas gathering rings can be changed arbitrarily according to different situations. There are cases of two, three or more than four layers. Shower arrangement. As mentioned above, ...

Abstract

The technical proposal of the invention provides a gas collecting ring of a spraying tower used for flue gas disposal and the spraying tower comprising the gas collecting ring, aiming at solving the technical problem that the flue gas is convergent to a spraying dense area, thus leading the flue gas to exist in a guide tower. The gas collecting ring comprises a first plate, one end of which is connected on the side wall of the spraying tower, furthermore, the first plate extends upwards and obliquely from the side wall of the spraying tower to the center of the spraying tower. The gas collecting ring and the spraying tower have the technical effects that the flue gas is guided to the middle part of the tower through the gas collecting ring and sweeps through the spraying dense area, the escaping of the flue gas is reduced, and the desulphurization efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and relates to a spray tower used in a thermal power plant wet flue gas desulfurization spray tower or other fields, and a gas gathering ring used in the spray tower. Background technique [0002] At present, the wet flue gas desulfurization technology plays an important role in the field of air pollution control in my country. The spray empty tower is the mainstream tower type of the wet desulfurization process. It has few internal components, so it is not easy to scale. Reverse contact is more conducive to the absorption of sulfur dioxide, but because the liquid film overlap near the wall of the spray tower is not as dense as other areas, it belongs to the weak spray area, also known as the spray dilute phase area, where the flue gas flow rate is relatively high. The ability of the spray liquid to capture sulfur dioxide is weak, which affects the desulfurization efficiency of the...
