The utility model has the beneficial effects that entire EG spray pipe is found during unpicking and washing other than pipeline is easily stifled,
White sundries on the plate of plate heat exchanger is more, and is easy product on plate and pipeline, and plate can pass through switching the
One plate heat exchanger and the cleaning of the second plate heat exchanger can not then solve, runing time increasingly long lines to solve on pipeline
Latus rectum is also smaller and smaller until blocking, to influence normally to produce to stop just can solve, the improvement structure of the utility model exists
The third pipeline and the 4th pipeline that directly can come into operation spare when accident come into operation conveniently, quick, pass through switching first pipe and the
Three pipelines switch second pipe and the 4th pipeline, problem or failure processing can be carried out online, caused by avoiding because of blocking accident
Parking waste discharge, it is obvious to effects of energy saving and emission reduction.
Detailed description of the invention:
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment:
The utility model is described in further detail With reference to embodiment:
Embodiment
As shown in Figure 1, a kind of improvement structure of EG spray pipe, including liquid seal trough 1, plate heat exchanger and scraper condenser
2, liquid seal trough 1 is connect with plate heat exchanger by first pipe 11, and plate heat exchanger passes through second pipe 12 and scraper condenser 2
Connection, first pipe 11 are equipped with circulation EG and pump the 3, first ball valve 21 and the first check valve 31, and second pipe 12 is equipped with second
Ball valve 22, plate heat exchanger include that the first plate heat exchanger 4 and the second plate heat exchanger 5, first pipe 11 pass through branch pipe respectively
It connect with the inlet of the first plate heat exchanger 4 and the second plate heat exchanger 4, is connect with 4 inlet of the first plate heat exchanger
Branch pipe is equipped with third ball valve 23, and the branch pipe connecting with 5 inlet of the second plate heat exchanger is equipped with the 4th ball valve 24, the second pipe
Road 12 is connect by branch pipe with the liquid outlet of the first plate heat exchanger 4 and the second plate heat exchanger 5 respectively, with the first plate-type heat-exchange
The branch pipe of 4 liquid outlet of device connection is equipped with the 5th ball valve 25, and branch pipe connect with 5 liquid outlet of the second plate heat exchanger is equipped with the
Six ball valves 26, further include third pipeline 13 and the 4th pipeline 14, and third pipeline 13 is equipped with the 7th ball valve 27 and second one-way valve
32, the 4th pipeline 14 is equipped with the 8th ball valve 28, and 13 one end of third pipeline is connect with the liquid outlet of circulation EG pump 3, the other end point
Not Tong Guo branch pipe connect with the first plate heat exchanger 4 and 5 inlet of the second plate heat exchanger, and with the first plate heat exchanger connect
The branch pipe connect is equipped with the 9th ball valve 29, and the branch pipe connecting with the second plate heat exchanger is equipped with the tenth ball valve 10, the 4th pipeline
14 one end are connect by branch pipe with the liquid outlet of the first plate heat exchanger and the second plate heat exchanger, the other end and scraper condenser
2 connections, and the 11st ball valve 11 is equipped on the branch pipe connecting with the first plate heat exchanger, it is connect with the second plate heat exchanger
Branch pipe is equipped with the 12nd ball valve 12.
In existing structure, only plate heat exchanger can be switched over, i.e. the first plate heat exchanger and the second plate-type heat-exchange
Device takes the structure of a preparation and a use, when needing to clean plate, switches another plate heat exchanger and continues to run, but if being pipeline
It blocks, then parking can only be taken to act on, loss in this way is very big, therefore the utility model increases two backup lines newly, i.e.,
Three pipelines and the 4th pipeline can be switched to third pipeline when first pipe blocks, equally, when the and pipeline occurs
When blocking, it can be switched to the 4th pipeline, parking accident caused by avoiding because of line clogging.It illustrates, when first pipe occurs to block up
Plug opens the 7th ball valve, second one-way valve and the 9th ball valve on third pipeline, closes the tenth ball valve (the first plate-type heat-exchange
Device is in running order), and the first ball valve, the first check valve are closed, then according to the flow for requiring the 7th ball valve of adjustment
Guarantee that EG spray system works normally, and starts to carry out dredging operation to first pipe.
The utility model solves line clogging situation, and such as because line clogging is stopped, loss is larger, and uses this reality
After novel, production continuous operating time substantially extends；Device stability is improved, the EG spray system of precondensation is five kettle streams
Journey important component, having lacked this EG spray system will affect final product；It, can be in not shadow after the utility model
In the case where ringing normal production, the precondensation spray flow of online processing blocking, it is entirely avoided cause vacuum because of underfed
The underproduction or the production accident of parking maintenance caused by ability difference；It is easy to operate, it is long using the time.
Only the utility model preferred embodiment is described above, but is not to be construed as the limit to claim
System.
