The utility model discloses evaporator device, include: the evaporimeter with to the steam of supply steam in the evaporimeter jar that converges to and intercommunication evaporimeter and steam converge the pipeline between the jar, the utility model discloses an evaporation plant is in steam jar department of converging or has seted up the maintenance manhole on the evaporimeter steam inlet pipe. Through the maintenance manhole that sets up, can make the maintainer conveniently get into steam and converge jar smoothly to inside entering into steam header through the heater steam inlet pipe, with carry out visual observation, inspection and converge jar and festival evaporimeter internal conditions, convenient maintenance and maintenance.

Description

Evaporation device

Technical Field

The utility model relates to an evaporation plant, especially an evaporation plant that can be used to carry out purification treatment to sewage, especially paper-making industry's sewage.

Background

At present, the application frequency of the evaporator, particularly the plate-type falling film evaporation, in the market is very high, the heat exchange element of the evaporator is made of a cold-rolled steel plate after surface treatment, and the formed evaporator has a continuous, wavy and uneven streamline smooth surface, so that the evaporator is favored by the market and is widely applied due to the advantages of high heat exchange efficiency, difficulty in scaling, convenience in cleaning and the like. In the working operation process, steam enters the heat exchange element to participate in heat exchange, waste heat flows outside and is heated and then boils to generate secondary steam, and the set process requirement is met. The steam that gets into heat exchange element inside forms behind the comdenstion water by condensation water piping discharge, other noncondensable gas and low boiling organic matter separation back by noncondensable gas piping discharge, and these processes need just must set up corresponding physics mechanism and accomplish specific function, and in actual conditions, will heat exchange element according to a determining deviation, a certain number group welding becomes the heater usually to guarantee required heat transfer area. In actual operation, corrosion or scaling cannot be completely avoided, but the structure of the existing equipment cannot visually check the corrosion and scaling conditions, the connecting bottom plate and the peripheral side plates forming the header are weak links, and slight vibration in transportation or use can cause welding spot cracking and leakage, so that the normal use of the equipment is seriously influenced. Once the problem has appeared, traditional structure can only cut out a window that can supply people to maintain the operation, and repair welding is good again with the window that cuts out after the maintenance, and this maintenance process degree of difficulty is very big, occupation time is very long, operational environment is abominable, the potential safety hazard when still can be in the operation after the maintenance simultaneously.

Disclosure of Invention

The utility model provides a can solve prior art not enough, be convenient for carry out the evaporation treatment's of inspection, maintenance device to the evaporimeter.

The utility model discloses an evaporator device, include: the evaporator and the steam that supplies steam in to the evaporator converge the jar to and the pipeline between intercommunication evaporator and the steam jar that converges, set up the manhole at steam jar department of converging.

The utility model discloses an another kind of realization mode of evaporimeter device is including: the evaporator and the steam that supplies steam in to the evaporator converge the jar to and the pipeline between intercommunication evaporator and the steam jar that converges, seted up the inspection manhole on the evaporator steam inlet pipe.

The utility model discloses an evaporation plant has seted up the inspection manhole in steam collection flow tank department, perhaps at the inspection manhole that sets up on evaporimeter steam inlet tube, can make the maintainer conveniently get into steam collection flow tank smoothly to inside entering into steam collection box through the heater steam inlet tube, with carry out visual observation, inspection collection flow tank and festival evaporimeter internal aspect, convenient maintenance and maintenance.

Drawings

Fig. 1 is a schematic diagram of a structural system of the present invention. Fig. 2 is another schematic structural diagram of the present invention. In the drawings: 1 is an evaporator; 2 is a noncondensable gas collection box; 3 is an evaporator noncondensable gas discharge pipe; 4 is a dirty condensed water collection tank; 5 is a secondary steam pipe which is communicated with other equipment to supply steam; 6 is an evaporator foul condensate water discharge pipe; 7 is a steam and clean condensed water header; 8 is a heat exchanger; 9 is an evaporator shell; 10 is an evaporator steam inlet pipe; 11 is a steam confluence tank; 12 is an inspection manhole; and 13 is an L-shaped welding bead.

Detailed Description

Fig. 1 and 2 show schematic diagrams of two embodiments of the present invention, which are used for treating waste liquid from paper making. The following is explained with reference to the drawings.

Referring to fig. 1, a steam collecting tank 11 for supplying fresh steam into the evaporator 1 is provided beside the evaporator 1 in the device of the present invention. The steam confluence tank 11 is provided with an inspection manhole 12, and a fresh steam pipeline (not shown in fig. 1) communicated with a fresh steam source is arranged on the steam confluence tank 11. In the present embodiment, the upper portion of the evaporator 1 is provided with a non-condensable gas header 2 for discharging non-condensable gas to the outside through an evaporator non-condensable gas discharge pipe 3; the middle part is provided with a dirty condensate water collection tank 4, the collection tank 4 is used for connecting an evaporator dirty condensate water discharge pipe 6, and is connected with a secondary steam pipe 5 for inputting secondary steam supplied by other heating equipment into the evaporator 1; the lower steam and clean condensate header 7 is connected to an evaporator steam inlet pipe 10 communicating with a steam header tank 11. In the device according to the embodiment of the present invention shown in the drawings, an evaporator 1 is used in which a heat exchanger 8 is provided with an L-shaped stripping and parting weld line 13.

Referring to fig. 2, the structure of this embodiment is basically the same as that of the previous embodiment, but the steam confluence tank 11 is not provided in the apparatus, and the steam is directly introduced into the evaporator 1 through the evaporator steam inlet pipe 10, and the service manhole 12 is directly provided on the evaporator steam inlet pipe 10. Such a configuration is suitable for those configurations that do not require the use of a steam header tank.

The utility model discloses in service, if need overhaul, can directly open and overhaul manhole 12, the maintainer can enter into steam and clean comdenstion water header 7 from this in, carries out the clearance and the daily maintenance of equipment inside and maintains, very convenient directly perceived.
