Abstract

The utility model provides a gas purifier, which comprises a housing as well as a gas inlet and a gas outlet on the housing. The gas purifier is characterized in that a dust removal and desulfurization solution layer, an adsorption layer, a purification layer and a steam-water separation layer are sequentially disposed in the housing from bottom to top. Carbon dioxide, large dust particles, coal tar and other impurities in the gas can be removed and separated through an alkaline solution layer, an active carbon adsorption layer, a condensation and dewatering layer, a quicklime layer and a dry distillation layer, thereby purifying the gas and improving the fuel value of the gas. The gas purifier has high gas purification efficiency, and each layer can be replaced, cleaned, and maintained conveniently.

Description

Gas purifier

Technical field

The utility model relates to a kind of cleaner, and the cleaner of the combustion gas that the combustion gas that especially a kind of purifying gas producer produces or other burning produce belongs to gas-purification equipment design and manufacturing technology field.

Background technology

Continuous minimizing along with coal-fired resource especially high-rank coals resource, the small gas producer that with the inferior coal is raw material comes into the market one after another, though can improve the utilization ratio of low value fuel, but because these early productions exist following critical defect: combustion gas does not obtain scientific and rational purification, comparatively serious to the pollution that surrounding environment causes, simultaneously also HUMAN HEALTH is brought injury, especially coal tar can not thoroughly be removed, easily hinder the conveying of combustion gas, even can't continue to use, thereby make this series products be restricted or ban use of.And gas-purification does not thoroughly also directly influence the combustion value of combustion gas, therefore, is necessary existing gas cleaning device is improved.

Summary of the invention

Have the pollution that gas-purification does not thoroughly bring now for overcoming, and combustion gas is carried freely, the combustion gas combustion is worth deficiencies such as low, the utility model provides a kind of gas purifier.

The utility model is finished by following technical proposal: a kind of gas purifier, comprise housing and on inlet mouth and air outlet, it is characterized in that being successively set in the housing the intravital dust-removal and desulfurizing liquid layer of shell from bottom to top, adsorption layer, filtering layer, purifying layer and carbonated drink separating layer.So that the combustion gas that allows gas producer produce, after gas supply pipe enters housing, gating is gone into the dust-removal and desulfurizing liquid layer of bottom, remove the sulfurous gas in the combustion gas, big dust particle, behind coal tar and other impurity, enter adsorption layer again, in further removing by adsorption layer, behind little dust and the coal tar, enter filtering layer, remove the part moisture content in the combustion gas after, enter purifying layer, after removing remaining sulfurous gas, enter the carbonated drink separating layer, slough remaining moisture content, make the dust in the combustion gas, tar, moisture and sulfurous gas thoroughly separate with combustion gas, thereby purifying gas improves combustion gas combustion value.

The housing that described dust-removal and desulfurizing liquid layer is positioned at liquid level is provided with liquid exit, and this outlet links to each other with drain pipe, and drain pipe is provided with liquid level control valve, so that discharge unnecessary fluid, keeps liquid level.

Place gac in the described adsorption layer, perhaps cinder, perhaps diatomite or other adsorption particle thing are with the dirt in the absorption combustion gas.

Described filtering layer is formed by stacking by polylith web plate with holes, and bottom-up, and the perforation density of web plate increases successively, so that isolate moisture content.

Place calcium oxide or other desulfurization, water-retaining agent in the described purifying layer, with further desulfurization, suction.

Described carbonated drink separating layer is made up of at least one molecular film, so that isolated water molecule and finish destructive distillation.

The utility model compared with prior art has following advantage and effect: adopt such scheme, can make sulfurous gas, big dust particle, coal tar and other impurity in the combustion gas, through basic solution layer, activated carbon adsorption layer, condensation dehydration layer, each self-applying of unslaked lime layer and destructive distillation layer is removed gradually, separates, thus purifying gas, improve combustion gas combustion value, the utility model is to the purification efficiency height of combustion gas, and each active layer is replaceable, clean, and is easy to maintenance.

Fig. 2 is the web plate structural representation.

Embodiment

Below in conjunction with accompanying drawing the utility model is described further.

The gas purifier that the utility model provides, comprise housing 1 and on inlet mouth 8 and air outlet 2, be provided with the alkali lye layer 7 that dust-removal and desulfurizing is used in the housing 1 from bottom to top successively, the adsorption layer 6 of interior dress activated carbon, filtering layer 5, the purifying layer 4 and the molecular film carbonated drink separating layer 3 of interior dress unslaked lime, as Fig. 1, wherein, filtering layer 5 is formed by stacking by the web plate 52 of polylith with holes 51, and it is bottom-up, eyelet 51 diameters on the web plate 52 constantly reduce, and eyelet 51 density increase successively, so that isolate moisture content, as Fig. 2, the housing that described dust-removal and desulfurizing liquid layer 7 is positioned at liquid level is provided with liquid exit, and this outlet links to each other with drain pipe 9, and drain pipe 9 is provided with liquid level control valve 10, so that discharge unnecessary fluid, keep liquid level.
