Embodiment 1

[0017] As shown in Figure 1, a calcium carbide furnace waste gas dust removal system, the top outlet of the waste gas chimney 1 of the calcium carbide furnace is connected to the waste gas venting pipe 2 obliquely downward, and one end of the recovery main pipe 3 of the calcium carbide furnace is connected to the waste gas obliquely upward The vent pipe 2 and the scrubber 4, the other end of the recovery main pipe 3 extends into the pool 6, and three first nozzles 5 are arranged in the waste gas vent pipe 2, and the water volume of each first nozzle 5 is 50m 3 / h, six second nozzles 6 are set in the scrubber 4, respectively located at different heights, and the water volume of each second nozzle 6 is 20m 3 / h, the first nozzle 5 is provided with a cut-off valve, and is interlocked with the waste gas valve of the waste gas chimney 1 .

[0018] For the convenience of maintenance, a pair of flanges with 8-shaped blind plates are arranged on the top of the waste gas chimney 1, and...

Embodiment 2

[0022] A calcium carbide furnace waste gas dust removal system. There are eight calcium carbide furnaces in the same row, which are the first to eighth calcium carbide furnaces in sequence. The top outlet of the waste gas chimney 1 of each calcium carbide furnace is connected to the obliquely downward waste gas. The venting pipe 2 and the scrubber 4 are arranged between the fourth and fifth calcium carbide furnaces, and the waste gas venting pipes 2 on the first, second, third and fourth calcium carbide furnaces are sequentially connected with the one on the slant upward. The recovery main pipe is connected, and the waste gas venting pipe 2 on the eighth, seventh, sixth and fifth calcium carbide furnaces is connected with another recovery main pipe on the slant in turn. Pools 6 are arranged symmetrically at the positions respectively, and the pools 6 communicate with the corresponding recovery main pipes, and communicate with the corresponding first nozzle 5 and the second nozz...

Abstract

The invention discloses a waste gas dust removal system for calcium carbide furnace. The system is characterized in that a top end outlet of a waste gas chimney of a calcium carbide furnace is communicated with a waste gas blow-down pipe which faces to downwards slantingly; each recycling header pipe of the calcium carbide furnace slants upwards to communicate the waste gas blow-down pipe with a scrubber tower; at least one first nozzle is arranged in the waste gas blown-down pipe; at least one second nozzle is arranged in the scrubber tower; the number of the calcium carbide furnace is preferably eight arranged in one row, each four share one recycling header pipe; the scrubber tower is arranged between two calcium carbide furnaces to supply water for the first nozzle, the second nozzle and the recycling header pipe through a water pool and a water pump; and nitrogen is always introduced at the two ends of the recycling header pipe. According to the system provided by the invention, the furnace gas is introduced to the scrubber tower by the chimney effect of the waste furnace gas, fog-like water is sprayed in the pipeline and the scrubber tower, and the dust in the waste gas is collected by making use of the affinity of dust to water, thereby achieving the effect that no black smoke comes out from the chimney.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and relates to the control technology of the dead gas of a calcium carbide furnace, in particular to a dust removal system for the dead gas of a calcium carbide furnace. Background technique [0002] A large amount of exhaust gas is produced during the operation of the calcium carbide furnace, and the dry dust removal system is mostly used for dust removal. The dry dust removal process is limited by the temperature of the waste gas flue. not effectively. Contents of the invention [0003] In order to overcome the above-mentioned shortcoming of the prior art, the object of the present invention is to provide a kind of calcium carbide furnace waste gas dedusting system, use the chimney effect of the waste furnace gas to introduce the furnace gas into the scrubber, and spray mist in the pipeline and the scrubber Use the affinity of dust to water to capture the dust in the barren ...
