Abstract
The utility model belongs to the technical field of waste heat of boiler flue gas utilizes, in particular to protecting against shock teflon heat exchanger. This protecting against shock teflon heat exchanger including the flue, is equipped with the teflon heat exchanger, characterized by in the flue: teflon heat exchanger the place ahead is equipped with a plurality of rows of protecting against shock tube banks. The beneficial effects of the utility model are that: through set up the protecting against shock tube bank before the heat exchanger, the striking of foreign matter exchange hot material can effectively stop or keep apart, improved the operational reliability of heat exchanger, reduced leak detection, shutoff and maintenance work.
Description
Technical field
The utility model belongs to residual heat from boiler fume and utilizes technical field, particularly a kind of protecting against shock teflon heat exchanger.
Background technology
Along with residual heat from boiler fume utilizes the further investigation of technology, teflon heat exchanger is applied to smoke heat exchanging system just gradually, especially in the technical field of deeply reducing exhausted smoke temperature, teflon heat exchanger, because of the splendid acid-resistant corrosion of its material, has good adaptability and reliability.But the insufficient strength of fluoroplastics tube bank own, the foreign matters such as the iron filings come off in flue can damage tube bank and produce leakage under the promotion of flue gas flow rate, considerably increase the work such as leakage detection, shutoff and maintenance.
Summary of the invention
The utility model, in order to make up the deficiencies in the prior art, provides a kind of protecting against shock teflon heat exchanger, can effectively stop or isolate the shock of foreign matter heat exchanging material, improve the operational reliability of heat exchanger.
The utility model is achieved by the following technical solution:
A kind of protecting against shock teflon heat exchanger, comprises flue, is provided with teflon heat exchanger in flue, it is characterized in that: described teflon heat exchanger front is provided with the tube bank of some row's protecting against shocks.
Described protecting against shock is restrained upper and lower two ends and is fixedly connected respectively by upper cover and low head and flue.
Described protecting against shock tube bank is 4 rows.
Described protecting against shock tube bank is fluorine plastic tube, and caliber is 10mm, and thickness is 1mm.
Import and the outlet of described teflon heat exchanger pipe row are connected to inlet union flange and outlet connection flange, and teflon heat exchanger pipe row fixed by fixed frame.
Described fixed frame adopts carbon steel fw frp material to make.
The beneficial effects of the utility model are: by arranging protecting against shock tube bank before heat exchanger, can effectively stop or isolate the shock of foreign matter heat exchanging material, improve the operational reliability of heat exchanger, decreasing leakage detection, shutoff and service work.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing 1 is structural representation of the present utility model;
In figure, 1 flue, 2 teflon heat exchangers, 3 protecting against shock tube banks, 4 upper covers, 5 low heads, 6 inlet union flanges, 7 outlet connection flanges, 8 fixed frames.
Detailed description of the invention
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment comprises flue 1, is provided with teflon heat exchanger 2 in flue 1, and teflon heat exchanger 2 front is provided with some row's protecting against shocks tube bank 3.Protecting against shock tube bank about 3 two ends are fixedly connected with flue 1 respectively by upper cover 4 and low head 5.Protecting against shock tube bank 3 is 4 rows.Protecting against shock tube bank 3 is fluorine plastic tube, and caliber is 10mm, and thickness is 1mm.Import and the outlet of teflon heat exchanger 2 pipe row are connected to inlet union flange 6 and outlet connection flange 7, and teflon heat exchanger 2 pipe row is fixed by fixed frame 8.Fixed frame 8 adopts carbon steel fw frp material to make.
Adopt a kind of protecting against shock teflon heat exchanger of the present utility model, along flue gas direction of advance after electric cleaner, arrange protecting against shock tube bank 3 and teflon heat exchanger 2 in desulfurizing tower gas approach 1 successively, teflon heat exchanger 2 adopts modularized design, utilizes fume afterheat heat-setting water or boiler air-supply.Protecting against shock tube bank 3 is 4 row's staggered arrangement, prevent foreign matter from directly impacting teflon heat exchanger 2, protecting against shock tube bank 3 is passed through upper lower perforated plate and flange and flue 1 and is fixed, upper cover 4 and low head 5 is welded respectively on the upper and lower surface of flue 1, for fixing protecting against shock tube bank 3, in upper cover 4 and low head 5, tube sheet is set for being uniformly distributed the pipe way distance of protecting against shock tube bank 3.Protecting against shock restrains 3 material selection fluorine plastic tubes, and this material has splendid acid-resistant corrosion, and most high-temperature resistant is at about 290 DEG C, can keep pipe performance in low-temperature flue gas environment.Protecting against shock tube bank 3 is inner without medium, is fixed by pipe clamp.
