Abstract
The utility model discloses a fume condensing and dewatering device for fume monitoring, which comprises a condenser, a strongly-dewatering glass heat exchanging pipe and a weakly-dewatering glass heat exchanging pipe. The fume condensing and dewatering device is characterized in that pipe bodies of the strongly-dewatering glass heat exchanging pipe and the weakly-dewatering glass heat exchanging pipe are positioned in the condenser, and an air outlet of the weakly-dewatering glass heat exchanging pipe is connected with an air inlet of the strongly-dewatering glass heat exchanging pipe. High-temperature fume passes through the weakly-dewatering glass heat exchanging pipe to exchange heat and be condensed so as to remove more water, and loss of fume components is less Then the fume passes through the strongly-dewatering glass heat exchanging pipe to be further condensed and dewatered, and loss of fume components is relatively reduced since needed dewatering volume is less. Accordingly, dewatering rate can be guaranteed while reduction of fume component loss can be guaranteed as far as possible.
Description
Technical field
The utility model relates to flue gas pre-processing device in a kind of fire coal boiler fume detection, is a kind of flue gas monitoring flue gas condensing de-watering apparatus specifically.
Background technology
High-temperature flue gas refers generally to the gas that thermoelectricity industry coal fired power generation engineering produces, as a kind of more special medium, general temperature range may reach 180 degree at the 50-120 degree under the particular case, generally can have dust and acidic materials such as SO2, NOX and moisture etc. in the flue gas in addition.So abominable measurement environment can cause bigger interference even severe impairment to accurate component measuring instrument.
In order to ensure measuring instrument service life of equipment and certainty of measurement, need carry out preliminary treatment to flue gas.Condenser is a flue gas preliminary treatment instrument commonly used, it is by refrigeration principles such as compressor, paltie effects, to the processing of lowering the temperature through the flue gas of glass heat-exchange tube, it is the condensate moisture in the flue gas, thereby isolate moisture a large amount of in the flue gas, guaranteed the service life and the certainty of measurement of later stage measuring instrument.Existing glass heat-exchange tube is divided into two kinds of strong dehydration-type and weak dehydration-types, and two kinds of glass heat-exchange tubes all are existing general products that are purchased.The dehydration rate of strong dehydration-type glass heat-exchange tube can reach more than 90%, but that the component in the flue gas is lost is more, reaches 5-10%.Weak dehydration-type glass heat-exchange tube dehydration rate is lower, has only 60%, and is few but the component in the flue gas is lost, and has only 1%.Therefore, in the preprocessing process of flue gas, try to achieve higher dehydration rate, will lose the component in the more flue gas, the accuracy that causes detecting reduces; If try to achieve the reservation of component maximum, then the dehydration rate of flue gas will be lower, will be bigger to the infringement of accurate detector device.
The utility model content
Technical problem to be solved in the utility model, be to overcome the defective that prior art exists, a kind of flue gas monitoring flue gas condensing de-watering apparatus is provided, adopt combination glass heat-exchange tube, can reach higher dehydration rate, reach lower flue gas composition simultaneously and lose.
The utility model flue gas monitoring flue gas condensing de-watering apparatus comprises condenser, strong dehydration-type glass heat-exchange tube and weak dehydration-type glass heat-exchange tube; It is characterized in that: the body portion of described strong dehydration-type glass heat-exchange tube and weak dehydration-type glass heat-exchange tube all places condenser, the gas outlet of weak dehydration-type glass heat-exchange tube connects the air inlet of strong dehydration-type glass heat-exchange tube, makes weak dehydration-type glass heat-exchange tube and strong dehydration-type glass heat-exchange tube constitute series connection.
High-temperature flue gas is earlier through weak dehydration-type glass heat-exchange tube, the heat exchange condensation, take off 60% moisture, but this moment, flue gas composition was lost less, and then through strong dehydration-type glass heat-exchange tube, further condensation dehydration is because the dehydrating amount that need this moment is less, therefore losing also of component reduced relatively, not only guarantees dehydration rate but also guarantee to reduce as far as possible the purpose that flue gas composition is lost thereby reached.
Description of drawings
Fig. 1 is the structural representation of the utility model flue gas monitoring with the flue gas condensing de-watering apparatus.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is elaborated.
As shown in Figure 1, flue gas monitoring flue gas condensing de-watering apparatus comprises condenser 1, strong dehydration-type glass heat-exchange tube 3 and weak dehydration-type glass heat-exchange tube 2; It is characterized in that: the body portion of described strong dehydration-type glass heat-exchange tube and weak dehydration-type glass heat-exchange tube all places condenser 1, the gas outlet 4 of weak dehydration-type glass heat-exchange tube connects the air inlet 5 of strong dehydration-type glass heat-exchange tube, makes weak dehydration-type glass heat-exchange tube and strong dehydration-type glass heat-exchange tube constitute series connection.
High-temperature flue gas is the air inlet 5 of the weak dehydration-type glass heat-exchange tube of process earlier, enter in weak dehydration-type glass heat-exchange tube 2 bodys, carry out the heat exchange condensation earlier, take off 60% moisture, condensed water is discharged by the condensate drain mouth of weak dehydration-type glass heat-exchange tube, but this moment, flue gas composition was lost less, flue gas enters in strong dehydration-type glass heat-exchange tube 3 bodys through the air inlet 6 of strong dehydration-type glass heat-exchange tube from the gas outlet 4 of weak dehydration-type glass heat-exchange tube again, carry out further condensation dehydration, because the dehydrating amount that need this moment is less, therefore losing also of component reduced relatively, not only guarantees dehydration rate but also guarantee to reduce as far as possible the purpose that flue gas composition is lost thereby reached.At last, discharge by the gas outlet of strong dehydration-type glass heat-exchange tube, enter flue gas and detect processing links through pretreated flue gas.
