As shown in Figure 2 a, the steam flow hole on upper water fender 18-1 can also be slot 18-1-1a, is not less than the maximum water level of this Hot water units, and on this, water fender 18-1 is connected with a point water plate 5, and namely slot 18-1-1a forms hole.The steam flow hole of slot form makes the processing of water fender simpler.
As shown in figures 1 and 3, the bottom surface of lower water fender 18-2 is fixed on the lower shoe of this shell 21, and on it, end face is positioned at the longitudinal axis place horizontal plane of drum 14.The two sides of lower water fender 18-2 are fixed on the sidewall of shell 21.The upper top edge of lower baffle plate is offered the groove mated with drum cross section, allows drum 14 pass from this groove.Go to the bottom on edge at lower water fender 18-2, some hole 18-2-1 are set.Described hole on described lower water fender, apart from described drum outer wall 20-40mm.Hole 18-2-1 on lower water fender 18-2 is around the arc shooting of described drum outer wall, and the hole 18-2-1 on lower water fender 18-2 is preferably distributed in the scope of 180 ° of second drum of corresponding drum.The concrete position of opening of lower water fender 18-2 is such as offer along the outer span boiler casing 30mm place of drum, hole 18-2-1 on lower water fender 18-2 is actually water flow hole, mainly avoid water in the overheated vaporization of water fender inferior horn place extended stationary periods, cause drum wall producing bubble and barrel temperature is too high and damage.
The aperture in this hole on upper and lower water fender is such as 6mm, and it is such as 70mm that the spacing of adjacent holes is preferably pitch of holes.
As shown in Figure 1, Figure 4 and Figure 5, described current speeder also comprises top water sprays 19, it to be arranged in shell 21 drum 14 around, this top water sprays 19 comprises a body as distributive pipe 19-1, the sidewall of this distributive pipe is offered some hole for water spraying 19-2, and this hole for water spraying 19-2 is arranged towards shell 21 rear portion being provided with hot water outlet; The distributive pipe of each top water sprays 19 is provided with water inlet, and this water inlet is coupled together by pipeline and connects the admission port of this condensing heat-exchange Hot water units.
As shown in Figure 4 and Figure 5, the distributive pipe 19-1 in described water jet is one around 180 ° of bend pipes of drum 14, and this bend pipe is arranged or uniform some described hole for water sprayings.This water jet is the upper sparge pipe 19a being arranged on drum 14 top.
Also can add in the above-described embodiments be located at drum 14 bottom lower sparge pipe 19b(as shown in Figure 5), the shape of lower sparge pipe 19b is substantially identical with top water sprays, 180 ° of settings just below drum.
The spacing of hole for water spraying 19-2 and drum 14 outer wall is 15 ~ 40mm.The aperture of described hole for water spraying is 5-10mm, such as, be 6mm.
Described hole for water spraying is opened on distributive pipe, towards the rear end of described drum, sees the arrow A in Fig. 1, also can slightly a little lower or surface thereof 3 ~ 8 degree backward backward.
Described water jet be arranged on adjacent one upper between water fender and a lower water fender.Preferably one above arranges a water jet between water fender and a lower water fender.Water jet relative to the position of described water fender is, described water jet is in a relatively more close water fender setting below between water fender described in adjacent two; Can be such as be 1/3 of two water fender spacing with the distance of a water fender below.
Also have a kind of situation, especially for small-sized Hot water units, water fender once can be set along the y direction of drum.
Can also be that the y direction along described drum arranges some described upper water fenders and described lower water fender, described upper water fender and the alternate setting of described lower water fender.
In above-mentioned two situations, because Hot water units is less, can not water jet be set.
Another situation is, the y direction along drum arranges at least one lower water fender, and drum arranges at least one described top water sprays, and described lower water fender and described top water sprays adjacent are with it that consistency from top to bottom is arranged, or the setting that is staggered.This is the very simple but good current speeder of effect of one.
Current speeder provided by the invention, if water fender is wherein as deflection plate, should be very common in field of heat exchange, all improve turbulence level and the flow velocity of shell-side fluid by arranging deflection plate in the housing of general tubular heat exchanger, but providing holes is but unprecedented structure on deflection plate.From general concept, arranging water fender is exactly stop current smooth flow in one direction, increases the turbulence level of current.But with regard to condensing heat-exchange Hot water units, for normal pressure duty, the temperature of drum is very high, but the flow velocity of water in shell is relatively very low, if just set up existing deflection plate, the height of deflection plate is lower, DeGrain, if the height of deflection plate increases, between two pieces of deflection plates, the temperature of water will raise fast, produce bubble, if and bubble can not be drained in time, just may pile up on drum sidewall, cause the isolation of drum and current local, in addition, existing deflection plate not with holes is set, the flow velocity of the close drum place water of deflection plate is slower, like this, barrel local temperature just may be caused too high, even scaling loss can be caused.This is because there is this situation, in the prior art, never used deflection plate to increase flow velocity and the turbulence level of current in water heat transfer space for normal pressure condensing heat-exchange Hot water units, therefore, also just can not increase the specification of this Hot water units, normal pressure condensing heat-exchange Hot water units keeps the large-scale development always lower because of the thermal efficiency and cannot improve and stagnate.The present invention creatively increases hole on water fender, namely deflection plate can be utilized to improve flow velocity and the turbulence level of water in shell, simultaneously, in time the bubble passing hole of generation can be drained, allow the especially water of water fender near drum place flow through water fender and not to be detained, on drum sidewall, so just not easily form bubble pile up.
Closer, the present invention also adds water jet on the basis of water fender, the recirculation water of a part for Hot water units is sprayed around the drum between water fender by water jet, the current of ejection can increase speed and the turbulence level of current on the one hand further, can further the bubble near drum wall be caught up with from drum wall in time on the other hand, again on the one hand, water lower for temperature is delivered directly to the higher temperature region near drum by water jet, and combustion chamber is improved for the efficiency of heating surface of the water in shell.
Therefore, be provided with this condensing heat-exchange Hot water units of the described high-efficiency heat exchanger comprising water fender and water jet, its hot water efficiency is improved significantly.
