Description
Technical field
The utility model relates to dust-laden saturated flue gas sampling preconditioning technique field, specifically is a kind of extremely frigid zones Flue Gas Pretreatment Device.
Background technology
Domestic existing flue gas discharge continuous monitoring system is that import equipment or production domesticization equipment all have a smoke sampling pretreatment unit at present.This device is removed earlier at the scene and is got flue dust in the sample gas, is delivered to the analysis cabinet by the high temperature trace pipe, removes the moisture in the sample gas then.Conventional equipment gets principle of work and process is:
As shown in Figure 1, ash-laden gas enters tubular filter tube 2 by probe skirt 1 and enters the filtering layer inner chamber and be cleaned during to smoke sampling, and most of dust of carrying secretly in the flue gas is trapped in the space and the outside surface of filtering layer inside.
Filtered smoke gas is imported into stopple coupon 13 through the effect of aspiration pump, this stopple coupon all adopts the high temperature trace pipe, conveying through these about 20 meters (generally being no more than 50 meters) high temperature trace pipes, enter pretreatment unit in the cabinet, through condenser, filtrator further dewater, dedusting, aspiration pump 16 is sent it into analyser and is measured gaseous contaminant content then.----tubular filter tube (scene)----stopple coupon----pretreatment unit-----analyser in the cabinet that is to say that flue gas flow can be reduced to: the probe skirt.
This flow process is mainly carried out dust removal process to flue gas at the scene.From the scene to the analysis area, carry through the insulation of high temperature trace pipe.Dewater again and dedusting at analysis area.This technology can only conform temperature higher regional occasion.
The main deficiency of above-mentioned process unit is: when ambient temperature was low, high temperature trace pipe load strengthened and very easily burns, and finally caused stopple coupon to lose efficacy.Because the integral heat insulation difficulty causes system pipeline band water, cause tested gas loss, data are inaccurate, and relevant pass through the pretreatment component seriously corroded, very easily stop up, finally cause systemic breakdown.

The technical scheme that the utility model technical solution problem is taked is: this extremely frigid zones Flue Gas Pretreatment Device comprises preprocessing part in situ part, stopple coupon, the cabinet; Situ part is provided with smoke sampling and back-blowing device, and this smoke sampling and back-blowing device comprise that probe skirt, tubular filter tube, blowback solenoid valve, ring-type heater, pressurized air are for pipe; The preprocessing part input end is connected with situ part by stopple coupon in the cabinet, and output terminal connects analyser; Described situ part also is provided with the constant temperature dehumidification case; The constant temperature dehumidification case comprises casing and is arranged on condenser, heating arrangement in the casing and the temperature controller that is electrically connected with it; The input end of condenser connects described tubular filter tube; The output terminal of condenser connects described stopple coupon.
During work, the ash-laden gas in the flue enters smoke sampling and back-blowing device, by the probe skirt, behind the sampling flue gas penetrating tubular cartridge filter, enters the inner chamber of tubular filter tube, enters the constant temperature dehumidification case through its sample gas outlet again.Flue gas behind the condenser receiving filtration in the constant temperature dehumidification case also carries out condensation process.Flue gas is lowered the temperature rapidly in the constant temperature dehumidification case and is dewatered.Flue gas dew point by dehydration can be reduced near the zero degree.Heating arrangement and temperature controller make constant temperature dehumidification case the temperature inside the box remain on the 0-35 degree.Satisfying in this temperature range dewaters requires and condenser working efficient height, and the life-span is long.Flue gas is at the scene through removing water treatment, only needs stopple coupon is heated to above zero get final product, therefore only needs process low temperature trace pipe transfer to as stopple coupon that preprocessing part gets final product in the cabinet, need not the high temperature trace pipe.
As further technical scheme of the present utility model:
In this extremely frigid zones Flue Gas Pretreatment Device, described condenser bottom connects a water tank, is used for receiving the also temporary transient condensed liquid that stores.
Further: the bottom of described water tank connects peristaltic pump, and peristaltic pump connects drainage arrangement.Peristaltic pump is discharged the liquid that stores in the water tank.
In this extremely frigid zones Flue Gas Pretreatment Device, pretreatment unit comprises secondary condenser, filtrator, aspiration pump, needle-valve in the described cabinet, and the input end of described secondary condenser is connected with stopple coupon, and output terminal connects filtrator.The condensed flue gas of secondary condenser enters filtrator under the aspiration pump effect.Filtrator carries out purified treatment after receiving flue gas.Flue gas after being purified enters analyser and measures gaseous contaminant content.
The beneficial effects of the utility model are: the sampling line of this Flue Gas Pretreatment Device need not to use the high temperature trace pipe, only needs to adopt low temperature trace pipe or common stopple coupon to get final product, cost reduces greatly, easy for installation and reliability improves, flue gas significantly reduces the corrosion of back level equipment (stopple coupon, solenoid valve, needle-valve etc.), the pretreatment component corrosion is lighter in the cabinet, system is prolonged serviceable life, make in the flue gas gaseous contaminant loss reach minimal value, simple in structure in addition, time between failures is long and cost is low.
