Spiral backing pipe in the filter recuperation of heat modular construction, spiral backing and circular pipe are by high-frequency welding or adopt heavy wall aluminium-alloy pipe machine-shaping one, more have excellent connection tight ness rating, difficult drop-off, crack than the heat-exchange tube that adopts the expand tube mode to process behind traditional fin sleeve pipe.Adopt in addition the dislocation stacked, can take full advantage of the hot-fluid of rising flue gas, working fluid in the heating tube, the recovery waste heat utilization rate reaches more than 75%; And thermal resistance is little, can not produce the fume emission difficult problem.This design and manufacture craft meet the law of thermodynamics fully, therefore will become the leading work in following evaporimeter, the direct-combustion boiler industry.
4, accumulate the shunt compensation component design reasonable, flow resistance is little;
For direct-fired evaporimeter and various boiler, steam oven, water system is a relatively stubborn problem, accidentally cuts off the water supply with regard to having, the problem such as booster occurs.As water system of the present utility model, accumulate the shunt compensation assembly and have more intrinsic advantage.At first, can directly be communicated with the low-temperature heat source that solar thermal collector produces by Pneumatic three-way valve; Secondly, can utilize again the Pneumatic three-way valve interface to dock with special-purpose work fluid hose, but rational allocation play with lacking with the effect of mending.The working fluid transition conduit that arranges makes working fluid enter smoothly each by solenoid electric valve and meets in the thermal evaporation assembly fluid cavity, the working fluid storage tank of depositing sufficient working fluid has played the effect in similar supply station, a whole set of supply pipe fitting thermal resistance is little, and anti-pressure ability is strong.
5, the sensing intelligent controller is safe and reliable, and is simple to operation;
If chance thermal evaporation assembly is the heart of evaporimeter, so, the sensing intelligent controller is exactly the brain of whole evaporimeter.The sensing intelligent control chart of sensing type thermodynamic evaporative component of the present utility model as shown in Figure 7.After the igniting start, move to the flow velocity control of fuel from the working fluid circulation, arrive again gas, complete monitoring is carried out in the collection of steam or hot water, and to issuablely cut off the water supply, overheated, superpressure, negative pressure exhaust, emptying take early warning and open up the benefit Intelligent treatment, guarantees the operation that whole equipment safety is orderly.Conventional boiler and direct-combustion furnace are to add computer monitoring with mechanically actuated, are sensor-type intelligent control and the utility model is carried out, and the people that only need have basic operating technical ability can operation on duty by the real examination a bit of time of training.
This shows, so complicated system is to just having become simply all the more in the intelligent sensing controler hand, and every operation is all finished in " gesticulating ".
