Background technology
This is novel be applied to emission source gas that stationary pollution source continuous blow-down monitoring system (being called for short CEMS) institute directly extracts except that water disposal facility.The higher discharging flue gas of temperature is delivered to the sample gas disposal unit of system after sampling pump extracts, cool off through this electronic refrigerator and remove water in the flue gas, and the body analytic unit of supplying gas is then measured the concentration of respectively polluting composition in the flue gas.This electronic refrigerator adopts PID control, and the temperature digital display also can arbitrarily be provided with.
At present, adopt the flue gas of heat pipe extraction-type sampling system to remove the mode that compressor refrigeration is often adopted in water treatment, the same with the principle of refrigerator refrigeration, compressor compresses refrigerant (ammonia or fluorine Lyons), temperature raises, and enters heating radiator, and heat release also is solidified as liquid ammonia or fluorine Lyons; Through the throttling valve osculum, the step-down cooling enters evaporator, absorbs heat from condenser then, and working medium is evaporated to steam, is inhaled in the compressor, so repeatedly operation.Flue gas is cooled in continuously during the condenser, the moisture content dewfall Cheng Shui under this low temperature in the flue gas simultaneously, and from condenser, discharge.Though this kind device can satisfy request for utilization, but still some deficiency: 1: belong to miniwatt refrigeration because the flue gas of system is handled, the efficient of compressor refrigeration is not high, and energy consumption is big, the cost height, and size is bigger.2: noise is bigger.3: owing to used refrigerant (ammonia or fluorine Lyons), as leak, very easily contaminated environment and being detrimental to health.4: cold and hot exchange velocity is slower, and is difficult for realizing high-precision temperature control.
The utility model content
In order to overcome above deficiency, this is novel to provide a kind of electronic refrigerator, this device adopts the principle of semiconductor electronic refrigerating sheet refrigeration, in miniwatt refrigeration category, the efficient height, energy consumption is low, cost is low, noise is little, volume is little, exchange velocity in light weight, pollution-free, cold and hot is fast, temperature control precision is high.All adopt the acid and alkali-resistance material with actuating medium gas parts in contact, therefore applicable various corrosive gass.
The technical scheme that this novel its technical matters of solution is adopted is: the huyashi-chuuka (cold chinese-style noodles) of refrigerating sheet is attached to the bottom surface of condensation tube, and heat-barrier material is laid in the condensation tube outside, and hot side is attached on the bottom surface of heat radiator, carries out air-cooled with fan to heat radiator; Flue gas into and out of condensation tube, is cooled to the temperature that is provided with pipeline (pipeline shape dish in condensation tube) in the shape of a spiral in condensation tube, moisture content dewfall and generate water and be discharged from the flue gas, and anhydrous flue gas is sent to gas analyzer after the condensation.
Adopt PID (proportion integration differentiation control) temperature controller, solid-state relay, platinum resistance temperature sensor to control the temperature (being the break-make of electron cooling sheet power supply) of condenser, the real accuracy control over temperature of energy, this PID temperature controller energy digital display temperature, and can arbitrarily be provided with, have warning, password setting, Long-distance Control and with function such as miscellaneous equipment information communication.For fear of cause a formula to regulate frequent break-make or the frequent generation/releasing of reporting to the police because of the measured value fluctuation, can carry out return difference (dead band, stagnant ring) and be provided with simultaneously.
This novel beneficial effect is, this device can be efficiently, promptly, stably the flue gas that is used to monitor of CEMS institute continuous drawing is carried out refrigeration and removes water treatment, compare with compressor refrigeration in this application (or miniwatt refrigeration category), have nuisanceless, pollution-free, energy consumption is low, cost is low, noise is low, volume is little, in light weight, advantage such as temperature control precision is high, anticorrosive, long-term continuous working, and is simple in structure.
