Embodiment
It is as shown in Figure 2,
The present invention includes the tank body 1 that has gas inlet 11 and gas exit 12; Tank body 1 is an airtight container; Gas inlet is connected to impure coal gas source, and what gas exit came out is exactly clean coal gas, and the purification of coal gas and filtration are to realize through the device of tank interior.Tank body 1 top be provided with for be convenient for changing filter core on inspection manhole 13 and for ease of the coal gas diffusion hole 14 of emission coal gas before the renew cartridge more, coal gas diffusion hole 14 place's mounted valves, last inspection manhole place mounting flange end cap.Because the volume of tank body 1 is bigger, maintenance needs personnel to enter into tank interior during with renew cartridge more, at the cat ladder 15 of the inner tank wall welding easy access personnel entering of last inspection manhole side-lower.Middle part horizontal welding in tank body 1 is useful on the porous card 16 of laying filter body, and porous card 16 is as the erecting stage of a filter body 2, and for ease of extracting filter body 2 out, the distance of porous card 16 end faces and tank body 1 end face should be greater than the height of filter body 2.The side-lower of tank body 1 is provided with for ease of removing contamination and checking the following inspection manhole 17 of filter body running condition.Wherein, picking and placeing through last inspection manhole 13 of filter body 2 carried out.Be provided with tank body bearing and mudhole 18 in tank body 1 bottom, mudhole 18 places are provided with valve, and mudhole can be in time external with the gas condensed water of separating, dust and other impurity drain tanks.
Like Fig. 3, shown in Figure 5, evenly be provided with several up and down penetrating through holes on the porous card 16, cooperating between filter body 2 and the porous card 16 is provided with gasket 21, is used for sealing.On porous card 16, be provided with the filter core holddown, to shown in Figure 8, said holddown comprises and is weldingly fixed on the porous card 16 compress bearing 22, be hinged on the pressing handle 23 that compresses on the bearing, the compressor arm 24 that cooperates with filter body like Fig. 6.
Like Fig. 4, shown in Figure 5, filter body 2 comprises outer orifice plate 25, interior orifice plate 26 and filter screen 27, said in orifice plate 26 be all with outer orifice plate 25 bottom and peripheral perforated tubbiness, the profile of outer orifice plate and filter screen all matches with the profile of interior orifice plate.Interior orifice plate 26 upper ends are provided with filter core flange 261, laterally are provided with a plurality of inner stiffener rings 262 along the endoporus intralamellar part, and for increasing filtration area, said Nei Jiajia circle adopts punched-plate to be made.The outside of interior orifice plate 26 is provided with filter screen 27, the outer orifice plate of the outside pressing of filter screen 27, and outer orifice plate, filter screen, interior orifice plate form sandwich structure, and outer orifice plate 25 adopts the mode of spot welding to fix with filter core flange 27 contact positions.When needing replacing or cleaning filter screen, grind off solder joint, outer orifice plate is extracted out.Behind replacing or the cleaning filter screen, outer orifice plate is pushed, outer orifice plate and the contact position spot welding of filter core flange get final product.Carbon leaching material 28 is equipped with in filter body 2 inside, and filtrate top uses Stainless Steel Cloth 29 to cover, and in order to impurity such as the tar in the absorption coal gas, naphthalenes, Stainless Steel Cloth is set prevents that getting into coal gas after gac from coming off forms secondary pollution.
If when replacing or cleaning filter body, remove the end cap at inspection manhole 13 places on the tank body top, the people gets into, and rotatably compresses handle, from compress bearing, takes out compressor arm, and filter body is extracted out from the through hole of porous card.
When needing filter body is installed; After the filter body that has a gasket is put into the through hole of card, compressor arm is placed on filter core flange top, presses pressing handle with hand; Compressor arm gets into and compresses in the bearing; Compressor arm is with porous card, gasket and filter core flange screw, and can guarantee does not have the gap between filter core flange and porous card, guarantees that coal gas all passes through filter element filtering.
Coal gas gets into the inlet plenum 31 of tank body 1 bottom from gas inlet; Outside from filter body enters into inside then; After filtering core filters, pass through the discharge chamber 32 on Alveolate activated carbon capable filtrate and Stainless Steel Cloth top, top again, get into the gas conveying tube net from gas exit.
Except that the described technical characterictic of specification sheets, be the known technology of those skilled in the art.
