Abstract
The utility model provides a variable flow heater which comprises a casing in which a heat exchanging pipe is arranged, wherein a front water chamber and a back water chamber are respectively arranged at the two ends of the casing. The casing is provided with a steam inlet and a steam outlet, and the inside of the front water chamber is provided with a water chamber partition board which divides the front water chamber into different front water chamber cavities. Valves with the same number with that of the front water chamber cavities are arranged on a cover board of the front water chamber, and a big valve is arranged on a cover board of the back water chamber. The utility model can adjust the on-off state of the valves during running, and thus the purposes of keeping the water speed in the heat exchanging pipe unchanged and changing the flow can be realized. The utility model has simple structure and convenient installation and use, and satisfies the requirement of the variable flow of the integral unit heat supply system.
Description
(1), affiliated field
The utility model relates to a kind of heat-exchanger rig, specifically a kind of heater that can the unsteady flow journey.
(2), background technology
Combined heat supply system can improve the whole economic efficiency of generating, heating system.After adopting " combined heat supply system " technology, be further to improve the heat supply benefit, require when different heat supply operating modes, be during being furnished with of its heat exchangers for district heating and be arranged in parallel, be arranged in series sometimes.This just requires the flow process number of heat exchangers for district heating to change, to adapt to the requirement of various heat supply operating modes.Two heat exchangers for district heatings are for example arranged.The water yield of hot net water of every heat exchangers for district heating of flowing through when being arranged in parallel is half of Total Water, and when arranged in series, the water yield of the hot net water of every the heat exchangers for district heating of flowing through is a Total Water.But the flow process number of existing heat exchangers for district heating all is changeless, can not satisfy the requirement of " combined heat supply system " and connection in series-parallel heating system patented technology.
(3), summary of the invention
The purpose of this utility model is to provide a kind of can change flow process easily, is particularly suitable for the unsteady flow journey heater of " combined heat supply system ".
The purpose of this utility model is achieved in that it comprises housing, in housing, be provided with heat exchanger tube, the two ends of housing have front water chamber and back hydroecium respectively, have steam inlet and outlet on the housing, in front water chamber, be provided with the hydroecium dividing plate that front water chamber is divided into different front water chamber chambeies, the valve that equates with the quantity in front water chamber chamber is set on the front water chamber cover plate, on the hydroecium cover plate of back, a big valve is set.
The utility model can also comprise:
1, described heat exchanger tube is a straight tube.
2, described hydroecium dividing plate has 1-3.
The characteristics of unsteady flow journey heater of the present utility model are: the heater heat exchanger tube adopts straight tube, rationally adopt valve during structural design and utilize original hydroecium dividing plate, be in operation and adjust each valve switch state, change flow process and make the purpose that water speed remains unchanged in the heat exchanger tube thereby reach.Of the present utility model simple in structure, easy to install, can satisfy the unsteady flow journey demand of " combined heat supply system ".
(4), description of drawings
Accompanying drawing is a structural representation of the present utility model.
(5), specific embodiments
For example the utility model is done description in more detail below in conjunction with accompanying drawing:
Accompanying drawing is a kind of structure that is suitable for the unsteady flow journey heater of two identical heaters, it comprises housing 8, in housing, be provided with heat exchanger tube 3, heat exchanger tube is a straight tube, the two ends of housing are respectively front water chamber 1 and back hydroecium 2, have steam inlet and outlet on the housing, are provided with the hydroecium dividing plate 7 that front water chamber is divided into two front water chamber chambeies in front water chamber, two valves 4,5 are set on the front water chamber cover plate, on the hydroecium cover plate of back, a big valve 6 are set.
Be that example illustrates operation principle of the present utility model still now,, export big valve 6 and be in closed condition that heater is two flow processs when heater is in when being arranged in parallel with two identical heaters.Hot net water is pressed the A direction of arrow and is flowed, and flows into heat exchanger tube from imported valve 4, flows out from outlet valve 5 after the back hydroecium is turned.
When heater is in arranged in series, export big valve 6 and be in full-gear, heater is a single process.Hot net water is pressed the B direction of arrow and is flowed, and flows into heat exchanger tube simultaneously from imported valve 4 and imported valve 5, through the back hydroecium directly from exporting big valve 6 outflows.
Because the arranged in series heater is compared with being arranged in parallel, the water yield that enters heater is twice; But this moment, and the heater that is arranged in parallel was two flow processs because the arranged in series heater is a single process, so its heat exchanger tube import total area ratio is arranged in parallel also and is twice.So the water velocity in unsteady flow journey heater heat exchanger tube can remain unchanged.
Can also be according to this principle by actual needs, heater can realize that single process becomes three flow processs, single process becomes four flow processs or the like.
Claims (3)
1, a kind of unsteady flow journey heater, it comprises housing, in housing, be provided with heat exchanger tube, the two ends of housing have front water chamber and back hydroecium respectively, have steam inlet and outlet on the housing, it is characterized in that: in front water chamber, be provided with the hydroecium dividing plate that front water chamber is divided into different front water chamber chambeies, the valve that equates with the quantity in front water chamber chamber is set on the front water chamber cover plate, on the hydroecium cover plate of back, a big valve is set.
2, unsteady flow journey heater according to claim 1, it is characterized in that: described heat exchanger tube is a straight tube.
