Detailed Description

The present invention will be described in further detail with reference to specific examples.

Example (b):

as shown in fig. 1 and 2, the utility model discloses a novel washing formula exhaust-gas treatment equipment, including spraying absorption cavity 1 and being located the water tank 2 that sprays absorption cavity 1 below, it is separated into a plurality of compartments 12 side by the baffle 11 of a plurality of vertical settings to spray absorption cavity 1, all compartments 12 form the air flue of turning back from top to bottom in the part above the liquid level of water tank 2, be equipped with the shower opening 13 that is located the upper portion in the compartment 12 and be located the filler district 14 of lower part, water tank 2 is connected and is used for coming absorption liquid pump toward circulating water pump 4 of shower opening 13, be equipped with drawer type filter screen 3 between filler district 14 and the liquid level of water tank 2, drawer type filter screen 3 inserts from the lateral wall level of water tank 2, drawer type filter screen 3 is equipped with the handle 31 that will use its extraction water tank 2 in the part that is located outside water tank 2. The partitions 11 are arranged in a staggered manner, and a chamber 12 is formed between adjacent partitions 11. The lower partition board is immersed in the liquid in the water tank 2, and only the upper part of the partition board can be used for gas circulation; the high partition plate is positioned above the liquid level of the water tank 2, and air can flow below the high partition plate, so that the chamber 12 can be trained into an air passage which turns back up and down, the spraying absorption cavity 1 is equivalent to a long air passage which is folded into a plurality of sections, and the size in a single direction is saved. The spray water sprayed from the spray opening 13 is extracted from the water tank 2, the packing area 14 can retain the sprayed liquid therein, and the waste gas must pass through the packing area 14 through the air passage, so that the water and the gas can be fully contacted, and the adsorption efficiency is improved. If the particles in the waste gas are more, impurities can fall into the water tank 2 along with spray water when water and air contact, but the drawer-type filter screen 3 can intercept some larger impurities to achieve the effect of solid-liquid separation; when a lot of impurities are deposited on the drawer type filter screen 3, the impurities can be drawn out of the water tank 2 through the handle 31 for pouring and cleaning, and then the water tank 2 is inserted.
