The utility model discloses a calandria heat supply network heater has the problem of having solved too big, the vibration of operation in-process noise, reaches the purpose of quick heat transfer.
Description
Technical Field
The utility model relates to a heating equipment, especially a calandria formula heat supply network heater.
Background
The heat supply network heater is the main equipment in the modern centralized heating system, is arranged at the head station of the heat supply network and provides heat source water for the whole urban heat supply network. The shell side of the heat supply network heater is steam, and the common heat supply network heater is a single steam inlet or a double steam inlet. Due to the large load of the heating network heater, the steam inlet on the shell side is generally large, and especially when the steam pressure is low (the lower the steam pressure, the lower the density), the higher the steam flow rate will be. The phenomenon is also the root cause of the phenomenon of excessive noise and vibration in the operation process of a plurality of heat supply network heaters.
The shell pass operation mode of the heat supply network heater is mainly condensation heat release, and steam can be expected to quickly fill the whole shell pass space, so that the steam is in full contact with the outer surface of the heat exchange tube, and the aim of quickly exchanging heat is fulfilled. However, the size of the heating network heater is large, the equipment is long, and the steam needs to have a certain running distance at the far end of the steam inlet, so that the steam inlet structure not only causes high flow rate of the steam around the steam inlet, but also increases the resistance of the steam, and is not beneficial to heat exchange.
SUMMERY OF THE UTILITY MODEL
The technical task of the utility model is to provide a calandria formula heat supply network heater among the above-mentioned prior art not enough, this calandria formula heat supply network heater has solved the problem of too big, the vibration of operation in-process noise, reaches the purpose of quick heat transfer.
The utility model provides a technical scheme that its technical problem adopted is: the novel water-vapor separator comprises a shell, a left end socket and a right end socket, wherein the left end socket and the right end socket are respectively arranged at the left end and the right end of the shell, a water outlet is formed in the upper portion of the left end socket, a water inlet is formed in the lower portion of the left end socket, a drain port is formed in the lower portion of the shell, a plurality of vapor inlets are formed in the upper portion of the shell, the plurality of vapor inlets are longitudinally arranged along the shell, and the plurality of vapor inlets are respectively communicated with a longitudinal communicating pipe.
The plurality of steam inlets are uniformly arranged along the longitudinal direction of the shell.
Each steam inlet is respectively connected with the longitudinal communicating pipe through a vertical connecting pipe, and the vertical connecting pipe is arranged at the lower part of the longitudinal communicating pipe.
The vertical connecting pipe and the longitudinal communicating pipe, and the vertical connecting pipe and the steam inlet are fixed in a welding mode respectively.
The middle of each group of supporting plates is provided with a steam inlet.
The longitudinal communicating pipe comprises a round pipe body and a plug, one end of the round pipe body is plugged by the plug, and the lower part of the round pipe body is connected with the steam inlet.
Compared with the prior art, the utility model discloses a calandria formula heat supply network heater has following outstanding beneficial effect: the shell side steam inlet adopts a discharge pipe, and a steam inlet is arranged in the middle of each group of supporting plates, so that the steam inlet amount of the heat supply network heater is relatively average. The steam can enter the shell for condensation and heat exchange in the shortest time. In addition, the steam entering from the shell is averaged, so that the steam flow speed on the surface of the tube bundle is reduced to a great extent, and the control on noise and vibration is well realized. Because steam can get into the tube bank rapidly in the short time inside for the heat transfer is more abundant, and area utilization is bigger, can effectively reduce the heat transfer area of equipment.
