Detailed description of the invention
The technical solution of the utility model is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model provides a kind of vacuum condensation cooler, comprise housing 1 and be positioned at the bobbin carriage 2 of housing 1 both sides, air inlet 3 is provided with above housing 1, for entering of gas (aniline gas etc.), housing 1 inside is provided with heat exchanger tube, is provided with pass partition 4 in the bobbin carriage 2 of wherein side, without heat exchanger tube just direct from material outlet 9 discharges after entering for preventing the medium in tube side from material inlet 8.
Be provided with reducer in the outside of housing 1, the shell wall that housing 1 is positioned at the part of described reducer offers air inlet band 5, and air inlet 3 is arranged on described reducer.Why reducer is set, because when not arranging, when gas enters housing 1 from air inlet 3, because the density of gas is little, its corresponding volume flow is very large, gas flow rate is very high, the gas entering housing 1 can be exchanged heat pipe and impacts and corrode, if arrange impingement baffle to alleviate impact by traditional anti-washing structure, need increasing device diameter to meet the erosion control height of import department, and erosion control effect is also undesirable, and the utility model is by arranging reducer, after gas enters reducer from air inlet 3, can impact on housing 1, the impact of high flow rate is born by housing 1, housing 1 is entered afterwards from the air inlet band 5 of housing 1 upper side, gas flow rate is now tending towards relaxing, the impact of exchange heat pipe significantly reduces.And by the setting of reducer, both added import erosion control height and turn avoid increasing device diameter, energy-saving consumption-reducing, safety and environmental protection.Because housing 1 is cylindric, compared with traditional impingement baffle, increase the circulation area of import department under equal erosion control height, reduce the drag losses of import department simultaneously, make even fluid distribution, be more conducive to heat exchange.
In the present embodiment, as shown in FIG. 2 and 3, reducer comprises the symmetrical conical shell 7 being fixed in shell ring 6 both sides of cylindric shell ring 6 and one end, the other end of conical shell 7 is fixed in housing 1, shell ring 6, conical shell 7 and partial shell 1 have been bonded the cushion space of gas, concrete, and shell ring 6 inwall is not less than 1/4 of the adapter external diameter of air inlet 3 to the distance of housing 1 inwall, namely there is enough erosion control height, to meet the actual internal area of air inlet 3.Air inlet 3 is communicated in shell ring 6, entering for gas.
As preferred technical scheme, air inlet band 5 is rectangular inlet band, and the circulation area of air inlet band 5 be the 3.5-5 of air inlet 3 adapter circulation area doubly, be preferably 4 times, and then flow velocity when can ensure that gas enters housing 1 is even.
In the present embodiment, described bobbin carriage 2 is provided with material inlet 8 and material outlet 9, lays respectively at above and below pass partition 4.
As illustrated in figures 4-5, the present embodiment also comprises channel nozzle and supports 10, this channel nozzle supports 10 and specifically includes built-in section 100 and external section 101, wherein be arranged on the inside of bobbin carriage 2 for built-in section 100 and one end extends to pass partition 4 place, be welded and fixed with pass partition 4, be connected to material outlet 9 for external section 101, its part is positioned at the inside of bobbin carriage 2, and it is outside that remainder is placed in described bobbin carriage 2; The built-in section of uniform some material of 100 outer walls circumference portals 102, and the present embodiment is specifically set to four, and fluid mechanics (recirculated water etc.) supports 10 through material 102 inflow pipe channel nozzles of portalling, and flows out from material outlet 9.
In the present embodiment, external section 101 part being positioned at bobbin carriage 2 is provided with some discharge orifices 103, is specially two, the tangent setting of inwall of this discharge orifice 103 and bobbin carriage 2 lowest part.Why tangent with the inwall of bobbin carriage 2 lowest part discharge orifice 103 is, be because, from Fig. 5, the part being positioned at bobbin carriage 2 inside for external section 101 can form hydrops, cannot to portal 102 discharges from material, so arrange discharge orifice 103 in its lowest position of bobbin carriage 2, hydrops is discharged, plays the effect of discharge opeing blowdown.
The present embodiment supports except pass partition 4 except supporting 10 by channel nozzle, can also support by arranging angle steel 11, concrete, the present embodiment is fixedly welded with some angle steel 11 between pass partition 4 and material outlet 9, the surrounding being distributed on material outlet 9 of this angle steel 11 symmetry, the present embodiment specifically selects 4 angle steel, is distributed in material outlet 9 around.Angle steel 11 adopts sequential welding to weld with between pass partition 4 and material outlet 9.
In order to better realize heat transfer effect, Selection of Tubes in Heat Exchangers stainless steel corrugated tube of the present utility model, this stainless steel corrugated tube is made up of thin-wall stainless steel material, specifically selects S30408 stainless steel material to make.Tube side can be made by this stainless steel corrugated tube, the heat transfer coefficient of shell side all strengthened, specific as follows:
A. the strengthening of heat transfer coefficient in tubes: be recirculated water in the pipe of the present embodiment, and the consecutive variations of undulatory heat exchanger tube circulation area can make the flow velocity of pipe Inner eycle water constantly change, the laminar condition of recirculated water can be broken like this, it is made to reach sufficient turbulence state, or attenuated layer laminar sublayer, heat transfer coefficient in tubes is enhanced.
B. outer enforcing condensation heat transfer is managed: traditional light pipe outer surface is because condensate liquid can not drip timely and leave heat exchange wall, thus form the thicker liquid film layer of one deck, this liquid film layer hinders the heat exchange of gas and tube wall, thus forms one deck thermal resistance, is unfavorable for condensation heat transfer.By the stainless steel corrugated tube of the present embodiment, its distinct waveforms had, make condensate liquid under gravity, more easily be gathered in the crest location of stainless steel corrugated tube, then drip smoothly, such condensate liquid is not easy the outer surface being attached to heat exchanger tube, subtracts the thickness of book liquid film, and in-tube condensation heat transfer coefficient is greatly improved.
As preferably, the below of described housing 1 is also provided with condensate outlet 12, is specially two, for discharge opeing blowdown.
Obviously, above-described embodiment of the present utility model is only used to clearly demonstrate the utility model example, and is not the restriction to the utility model embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.All do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., within the protection domain being all included in the utility model claim.
