Abstract
The utility model provides an indirect heater, and the flow rate inside the pipe of which can be adjustable. The indirect heater solves the defects that the traditional indirect heater can not suit for the changing of the coil flow of the heat exchanger, and the heat exchange effect is not good or the resistance of the coil is increased. An inlet influx is arranged on the inlet of a switching coil. An outlet influx is arranged on the outlet of the switching coil. The switching coil at least has two groups. Valves are separately arranged with each group of coils on the front end of a heat exchanger. Valves are separately arranged with each group of coils on the back end of the heat exchanger. A valve is arranged between the two groups of coils. The changeable flow rate can be adopted by the free switch of the valves. The reasonable flow rate can be obtained finally, which can ensure that the heat exchange effect and resistance both can satisfy the using requirements at the same time.
Description
Technical field
But the utility model relates to the indirect heater of flow velocity in a kind of adjustable pipe, belongs to boiler, heating furnace field.
Background technology
Traditional indirect heater, by the heat exchanger that coil pipe is formed, velocity in pipes changes along with the changes in flow rate that is heated working substance system, and the SR (pressure falls) and the coefficient of heat transfer are also along with variation.When the flow significant change of working substance system, when especially being multiplied (minimizing), make the heat exchange velocity in pipes of heat exchanger obviously increase (reducing), the heat exchange effect of heat exchanger tube improves (reduction) greatly, makes the heat exchanger resistance significantly strengthen (minimizing) simultaneously.When above-mentioned variation reaches certain numerical value, can make heating furnace can not satisfy instructions for use owing to the coil pipe resistance is excessive.At present, except the quantity in parallel of increasing heat exchange tube diameter blindly and increase heat exchanger tube, also do not have more effective way to solve indirect heater and can't satisfy the problem of instructions for use because of the flow significant change causes it.
Summary of the invention
The utility model provides a kind of indirect heater of regulating flow velocity in the heat exchange tube, the structure uniqueness, can be according to the variation that is heated flow system flow, adjusting the heat exchanger tube velocity in pipes by switch valve makes it in certain scope, to obtain heat exchange effect preferably simultaneously, satisfy the requirement of heat exchanger resistance, finally reach the adaptive system changes in flow rate, satisfy the purpose of customer requirements.
Technical scheme is: but the indirect heater of flow velocity in a kind of adjustable pipe, main body is an indirect heater, switch the coil pipe import import manifold is set, outlet is provided with the outlet manifold, switch coil pipe and be at least two groups, every group of coil pipe is provided with valve respectively at heat exchanger front end place, and the place is provided with valve respectively in heat exchange its rear end, is provided with valve between two groups of coil pipes.
Described switching coil pipe is arranged in the outer independent heat exchanger of steam generator.
Compare traditional indirect heater, behind the employing switch plate Manifold technology, can obtain rational flow velocity, guarantee that heat exchange effect and drag energy meet the demands simultaneously according to the variation of flow.

The specific embodiment
Embodiment one:
As shown in Figure 1, 2, but the indirect heater of flow velocity in this adjustable pipe, main body is traditional indirect furnace body 1, comprise smoke pipe 9, flue 10, switching coil pipe 3 is arranged in the steam generator 12 internal upper part heat exchangers, switch coil pipe 3 imports import manifold 2 is set, outlet is provided with outlet manifold 1, switching coil pipe 3 is two groups, every group of coil pipe is provided with import switch valve A1, outlet switch valve A2 respectively at heat exchanger front end 6 places, 7 places are provided with valve A3, A4 respectively in the heat exchanger rear end, are provided with valve B1, B2, B3 between two groups of coil pipes.
When being heated working medium and being in big flow status (gas by), open import switch valve A1, outlet switch valve A2 and valve A3, A4, valve-off B1, B2, B3, make to be heated working medium and to flow through simultaneously and respectively organize heat exchanger tube and elbow 5, guarantee that coil pipe resistance and heat exchange effect meet the demands simultaneously by heat exchanger.
When being heated working medium and being in low discharge state (liquid by), close import switch valve A1, outlet switch valve A2 and valve A3, A4, Open valve B1, B2, B3, make and be heated working medium and successively flow through and respectively organize heat exchanger tube and elbow, pass through heat exchanger, increase the heated stroke of working medium, fully heat exchange.
Embodiment two:
As shown in Figure 3, this switching coil pipe 3 is arranged in the outer independent heat exchanger 11 of steam generator 12, steam generator 12 and separately between the heat exchanger 11 by connecting communicating pipe.Other structure is identical with embodiment one.
