Index to meet the needs of process conditions, while is also one of capital equipment for improving energy utilization rate.Heat exchanger industry is related to
Nearly 30 multi industries such as HVAC, pressure vessel, sewerage disposing equipment, chemical industry, oil, mutually form industry chain (supply chain).Data are shown
Chinese heat exchanger industrial market scale in 2010 at 50,000,000,000 yuan or so, focus primarily upon oil, chemical industry, metallurgy, electric power, ship,
The fields such as central heating, refrigeration air-conditioner, machinery, food, pharmacy.
However, traditional fixed tube-sheet exchanger, is only applicable to the smaller operating mode of the temperature difference, because of tube side and shell side medium temperature not
Equally, the swell increment of the two differs, and the material difference of the two in addition, and expansion system is variant, and exchanger tubes and tubesheets is caused to connect
Partial destruction is connect, leakage is serious, it is impossible to normal operation.
Utility model content：
In order to solve the above-mentioned problems in the prior art, the utility model provides a kind of tubular sheet heat exchanger.
One embodiment of the utility model provides a kind of tubular sheet heat exchanger, including：Thimble, bobbin carriage, heat exchanger tube, it is described
Thimble one end side wall upper part is provided with the first liquid inlet, other end lower sidewall is provided with the first liquid outlet, the thimble
Both ends of the surface are disposed with the first tube sheet, outer end plate, and the thimble is additionally provided with close to the end face of first liquid inlet
Two tube sheets, second tube sheet are arranged between first tube sheet and outer end plate, first tube sheet and second tube sheet
The heat exchanger tube is all connected with, second liquid outlet is provided on the outer end plate of first liquid inlet side, close to described
Second liquid entrance is provided on the outer end plate of first liquid outlet side；Several baffle plates are additionally provided in the thimble, it is described
Baffle plate interlock and be vertically arranged on the thimble inner wall, wherein, formed between first tube sheet and second tube sheet
One cavity is provided with baroceptor, alarm device in the cavity.
Further, it is additionally provided with air bleeding valve on the thimble.
Further, the distance between first tube sheet and second tube sheet are 2cm-4cm.
Further, first tube sheet and second tube sheet are stainless steel plate.
The tubular sheet heat exchanger of the utility model is by setting two layers of tube sheet so that heat exchanger tube cold and hot exchange between medium is carried out
When, the bulking effect of exchanger tubes and tubesheets junction is reduced, reduces swell increment, is reduced because tube sheet and heat exchanger tube are due to material
Difference leads to the generation that medium caused by expanding inconsistent caused tubing loss is revealed, and improves the service life of heat exchanger,
In addition, by setting baroceptor and alarm device between two layers of tube sheet, between two layers of tube sheet is detected air pressure occur compared with
During big variation, show that exchanger tubes and tubesheets junction has occurred and that or may reveal, alerted, carried using alarm device
Awake user pays attention to overhauling.
