Description
Technical field
The present invention relates to field of heat exchange equipment, are specially a kind of heat exchanger assembly that can empty feed back.
Background technology
In heat-exchanger rig field, in heat transferring medium generally require to be emptied in plant maintenance.In order to be perfused
When bubble emptying needs, the flowing of heat transferring medium is often arranged to bottom in and top out.Thus, in blowdown, often under
End carries out discharge, and from upper end breathe freely/leak.
For the port of lower end, due to needing to carry out feed operation in normal operation, and let out in blowdown
Material operation, therefore the valve for generally requiring to set two-way discrete in actual use is controlled, and be easy to cause control system complexity
And the conflict of operation operating status easily occurs, equipment cost also increases in addition.
The content of the invention
It is an object of the invention to provide a kind of heat exchanger assemblies that can empty feed back, can overcome of the prior art
Defect.
A kind of heat exchanger assembly that can empty feed back according to the present invention, including the multiple tube assemblies interconnected on longitudinal direction,
Each tube assembly includes lower floor's pipe that upper strata is managed and connected with the upper strata pipe, and the upper strata pipe and lower floor's pipe distinguish water
Plain cloth is put, wherein the lower floor pipe in each tube assembly is connected with feed pipe, each on described in the tube assembly
Layer pipe is connected with discharge nozzle, which is characterized in that the upper end of the feed pipe is arranged with charging blowdown valve, the charging blowdown valve bag
It includes outer barrel and the inner cylinder saddle that can slide up and down between the outer barrel and the feed pipe, the outer barrel includes
The shaft end substrate being carried at the lower end of the feed pipe and the circumferential sidewall around the feed pipe, in the circumference
Charging transverse tube is provided on the left of wall portion, right side is provided with blowdown transverse tube, be provided on the side wall of the feed pipe respectively with institute
State charging transverse tube and the feed inlet and pulp cutlet of the alignment of blowdown transverse tube；It is set respectively on the left side wall and right side wall of the inner cylinder saddle
Intercommunicating pore and lower intercommunicating pore are equipped with, when the inner cylinder saddle is in upper position, the lower intercommunicating pore is by the pulp cutlet
It is connected with the blowdown transverse tube, the charging transverse tube and the feed inlet are separated by the inner cylinder saddle at this time；When the inner cylinder
Saddle is at lower position, and the upper intercommunicating pore connects the feed inlet with the charging transverse tube, at this time the pulp cutlet
It is separated with the blowdown transverse tube by the inner cylinder saddle.
Whole device can realize the switching of two operations during a control operation, can fundamentally prevent to transport
The problem of row state contradicts；And two kinds operate with a valve member, effectively reduce the complexity of control system, drop
Low equipment cost.
Description of the drawings
Fig. 1 is the overall schematic of the heat exchanger assembly of the present invention.
Fig. 2 is the example arrangement schematic diagram of the valve in Fig. 1.
Specific embodiment
The present invention is described in detail for connection with figures below.
With reference first to Fig. 1, a kind of heat exchanger assembly that can empty feed back, including the multiple tube assemblies interconnected on longitudinal direction
1, each tube assembly includes lower floor's pipe 12 that upper strata is managed and connected with the upper strata pipe 11, the upper strata pipe 11 and the lower floor
Pipe 12 distinguish it is horizontally disposed, wherein lower floor's pipe 12 in each tube assembly is connected with feed pipe 2, each pipe group
The upper strata pipe 11 in part is connected with discharge nozzle 3, which is characterized in that the upper end of the feed pipe 2 is arranged with charging blowdown valve
20, the charging blowdown valve 20 includes outer barrel 202 and can be upper and lower between the outer barrel 202 and the feed pipe 2
The inner cylinder saddle 203 of slip, the outer barrel 202 include be carried on the shaft end substrate 2051 at the lower end of the feed pipe 2 with
And the circumferential sidewall around the feed pipe 2, charging transverse tube 21 is provided on the left of the circumferential sidewall, right side is set
There is blowdown transverse tube 22, be provided with what is be aligned respectively with the charging transverse tube 21 and blowdown transverse tube 22 on the side wall of the feed pipe 2
