Abstract

The invention discloses an external desulfurization circulating spraying system. The system comprises a desulfurizing absorption tower and a safety protection mechanism, the outer end of the middle part of the desulfurizing absorption tower is connected with a circulating mother tube outside the tower, spraying branch tube overhaul valves are arranged at the bottom ends of the circulating mother tube outside the tower, a nozzle is mounted at the outer end of every spraying branch tube overhaul valve, circulating pumps are arranged at the left end and the right end of the bottom end of the desulfurizing absorption tower, the bottom end of the desulfurizing absorption tower is connected with a circulating pump inlet shut-off valve, an inlet filter screen is installed at the bottom end of thecirculating pump inlet shut-off valve, the safety protection mechanism is located at the outer side of the circulating pumps, and a locking mechanism is mounted at the outer side of the circulating mother tube outside the tower. The external desulfurization circulating spraying system makes a safety protection fixing plate and a rocking rod rotate relative to each other through movably connectingthe safety protection fixing plate and the rocking rod, so the rocking rod is rotated and adjusted to carry out transmission operation, and the safety protection fixing plate is stably used by fixingthe safety protection fixing plate and the desulfurizing absorption tower.

Description

technical field

[0001] The invention relates to the technical field of an external desulfurization circulating spray system, in particular to an external desulfurizing circulating spray system. Background technique

[0002] The desulfurization technology currently implemented in China, whether it is a power plant, a steel mill, or a coking enterprise, has set higher requirements on the emission concentration of sulfur dioxide, and the emission concentration of sulfur dioxide is 35mg / Nm3 or lower. With higher requirements for sulfur dioxide emission concentration and wider industries for desulfurization, an external desulfurization circulation spray system desulfurization technology has emerged as the times require.

[0003] The conventional desulfurization spray layer is the spray layer inside the tower, which adopts glass fiber reinforced plastic pipes or rubber-lined pipes. The pipe network and support beams are arranged inside, and the spraying direction of the nozzles is...

Examples

example 1

[0025] Its structure is mainly to arrange the slurry circulation main pipe outside the tower, the spray main pipe is arranged circumferentially, and the branch pipes are evenly distributed at the lower part of the main pipe according to the angle, and the nozzle 4 is arranged at the end of the branch pipe, and the nozzle 4 is inserted into the absorption tower. The spray main pipe can be rubber-lined pipe or glass fiber reinforced plastic pipe, the spray branch pipe is made of glass fiber reinforced plastic pipe, the nozzle 4 adopts the spiral cone atomizing nozzle 4 with a spray angle of 120 degrees, and the atomized droplets of the conical structure sprayed by the nozzle 4, in order to ensure All the flue gas passes through the layer of atomized droplets, and the atomized droplets must cover the entire section of the absorption tower;

[0026] After adopting the desulfurization technology of the external desulfurization circulation spray system, the nozzles 4 are all arranged...
