3results about How to "Improve dust removal" patented technology

The denitration and dust removal integrated biomass grate boiler comprises a second flue, a third flue and a fourth flue which are sequentially connected with an outlet of a hearth, the lower end of the second flue is communicated with the lower end of the third flue, and the upper end of the third flue is connected with the upper end of the fourth flue through a furnace top turning flue. A first platen superheater is arranged at the upper part of the hearth, a second platen superheater is arranged in the second flue, a coiled pipe superheater is arranged in the third flue, and denitration equipment, an economizer and a tail heating surface are sequentially arranged in the fourth flue according to the flowing direction of flue gas; dust removal equipment is arranged in the furnace top turning flue, and the dust removal equipment and denitration equipment are supported on a boiler body steel frame. The dust removal equipment and the denitration equipment are also arranged in the range of the boiler body, so that compared with the prior art, the lengths of the inlet flue and the outlet flue are greatly shortened, the heat dissipation loss is reduced, the boiler efficiency is improved, and the dust removal and denitration effects can be improved; and the floor area is small, and the construction cost is low.

The utility model discloses a flue gas dedusting and desulfurizing device which comprises a tank body, a rotational flow plate assembly, a rotary packing assembly and a fixed packing assembly are sequentially arranged in the tank body from bottom to top, a rotating shaft is rotatably arranged in the tank body, the rotational flow plate assembly and the rotary packing assembly are both fixedly connected to the rotating shaft, and the bottom end of the rotating shaft penetrates through the inside and the outside of the tank body. The side wall of the bottom of the tank body is communicated with an air inlet pipe, the top of the tank body is communicated with an exhaust pipe, a flow guide assembly is arranged between the rotational flow plate assembly and the rotary filler assembly, a first liquid distributor is arranged in the center of the rotary filler assembly, and a second liquid distributor is arranged above the fixed filler assembly. The first liquid distributor and the second liquid distributor are connected with the liquid storage tank through a circulating pipe, and a circulating pump is arranged on the circulating pipe. After the rotational flow plate assembly, the rotary filler assembly and the fixed filler assembly are arranged in the tank body for three-stage collaborative desulfurization, the desulfurization efficiency can be effectively improved, and the occupied area is reduced.

This utility model discloses a metal door and window cutting device. A mounting plate is fixedly installed on the upper surface of the workbench. A bracket is slidably installed above the mounting plate, and a cutting disc is located below the bracket. Limiting rods slide through both sides of the cutting disc. A pressure plate is fixedly installed at the bottom of the limiting rods, and a limiting plate is threadedly fixed to the top of the limiting rods. A support rod is fixedly installed on one side of the limiting plate, and a lever is rotatably installed at the top of the support rod. A column is fixedly installed on the upper surface of the bracket, and the top of the column is rotatably connected to the lower surface of the lever. Two symmetrically arranged dust suction pipes are slidably installed on the top of the bracket. Through the limiting rods, pressure plate, lever, and dust suction pipes, the two sides of the cutting seam can be further fixed during cutting, preventing saw blade deviation and reducing cut quality. Simultaneously, it ensures dust removal and elimination of irritating odors during cutting of door and window components of different thicknesses.
