Abstract
The utility model discloses a formaldehyde plant flue gas waste heat recovery system which comprises a saddle and a tubular shell type heat exchanger arranged on the saddle transversely. The tubular shell type heat exchanger comprises a heat exchanging area and a front sealing head and a rear sealing head which are arranged at the two ends of the heat exchanging area respectively and are communicated with a shell pass, and smoke passes through the shell pass. The tubular shell type heat exchanger tube pass is filled with saturated hot water, and the side face of the tubular shell type heat exchanger is provided with a hot water side sealing head and a steam side sealing head, wherein the hot water side sealing head and the steam side sealing head are communicated with the tube pass. The formaldehyde plant flue gas waste heat recovery system reduces flue gas emission temperature, avoids thermal pollution, enables smoke to be utilized to the maximum extent, can reduce power consumption of a incinerator effectively, and reduces equipment cost.
Description
Technical field
The utility model relates to the formaldehyde preparation device technical field, relates in particular to formaldehyde tail gas and burns the full-time flue gas waste heat recovery apparatus that produces.
Background technology
The tail gas amount that silver method Formaldehyde Production formaldehyde per ton produces is about 600Nm3, because wherein hydrogen content is higher, and also has the fuel gas such as a small amount of methane, methyl alcohol, formaldehyde.Tail gas directly discharges environment is formed pollution.So the tail gas that domestic silver-colored method formaldehyde production device produces all is directly to burn by burner, the high temperature that utilizes burning to produce flue gas produces steam and energy utilization.
But because that the energy utilization utilizes is unreasonable, it is higher often to cause directly being disposed in the atmosphere flue-gas temperature, not only causes thermal pollution, and unreasonable causing of the heat exchange structure of stove own, and the incinerator appts power consumption is large, and equipment cost is higher.
Summary of the invention
Goal of the invention: for problem and the defective of above-mentioned existence, the utility model provides a kind of formaldehyde plant flue gas waste heat recovery system, can Effective Raise flue gas waste heat recovery efficient, fume afterheat is at utmost utilized and can effectively reduce the power consumption of incinerator, reduce equipment cost.
Technical scheme: for achieving the above object, the present invention is by the following technical solutions: a kind of formaldehyde plant flue gas waste heat recovery system, comprise saddle and laterally be located at shell-and-tube heat exchanger on this saddle, this shell-and-tube heat exchanger comprises heat transfer zone and is located at respectively the heat transfer zone two ends and the front head that is communicated with shell side and rear head that this shell side is used to walk flue gas; Described pipe for shell-and-tube exchanger journey is filled with saturated hot-water, and the side is provided with hot water side end socket and the steam side end socket that is communicated with tube side.
As preferably, described front head and rear head are provided with baffle plate with the heat transfer zone junction respectively, and this baffle plate is distributed with a plurality of distribution holes.
As preferably, the heat exchanger tube in the described heat transfer zone is that aluminum is around the fin-tube heat pipe.
Beneficial effect: compared with prior art, the utlity model has following advantage: reduced smog discharge temperature, avoided thermal pollution, gas energy is at utmost utilized and can effectively reduce the power consumption of incinerator, reduced equipment cost.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Saddle 1, front head 2, baffle plate 3, steam side end socket 4, hot water side end socket 5, heat exchanger tube 6, rear head 7.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment only is used for explanation the utility model and is not used in restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present utility model.
As shown in Figure 1, a kind of formaldehyde plant flue gas waste heat recovery system comprises saddle and shell-and-tube heat exchanger, and wherein shell-and-tube heat exchanger laterally is installed on the saddle, this shell-and-tube heat exchanger comprises front head, heat transfer zone and rear head, and wherein front head and rear head are located at respectively the two ends of heat transfer zone.High-temperature flue gas by incinerator out after, entered into the shell side of heat exchanger by front head, for preventing flue gas skewness in device, between front head and the heat transfer zone and between rear head and the heat transfer zone baffle plate is being set, this baffle plate distributes according to fluid a large amount of distribution holes is set, thereby can avoid the fluid skewness to cause flue gas at the uneven impression heat exchange efficiency of the heat exchange of heat transfer zone.In addition, the main heat exchange element of heat transfer zone adopts around wing formula heat exchanger tube, is provided with hot water side end socket and steam side end socket in the side of heat transfer zone, and is communicated with heat exchanger tube.Wherein inject saturated hot-water by the hot water side end socket in the heat exchanger tube, produce steam behind hot water and the flue gas adverse current contact heat-exchanging and discharged by the steam side end socket.
Flue gas directly enters this device through the high-temperature flue gas behind the incinerator after the formaldehyde plant burning, directly discharges after progressively producing behind the steam hot-water heating system heat exchange with formaldehyde plant with the saturation water heat exchange.This formaldehyde plant flue gas waste heat recovery apparatus, flue gas medium is walked shell side, and since the thermal resistance of heat exchange substantially all in fume side, this device is because flue gas is walked shell side, the fume side circulation area increases, the fume side pressure drop reduces greatly, thus effective Reduction of power consumption.And adopt outer fin heat exchange pipe, changed the liquid form of the outer flue gas of pipe, strengthened heat exchange, can effectively reduce the heat exchange space required, and external finned tube can increase pipe external expansion heat transfer area greatly, thereby reduce equipment cost.
