Abstract
The invention discloses an intelligent auxiliary circulating water pipe waste heat boiler. The intelligent auxiliary circulating water pipe waste heat boiler comprises a boiler chimney, a circulating water pump, a coal economizer, an evaporator, a superheater and an intelligent control device. The circulating water pump is connected with a water tank in the boiler chimney through a pipeline. The coal economizer is installed on one side of the boiler. The evaporator is installed between the coal economizer and the superheater. The intelligent control device is arranged on the other side of the boiler. By means of the intelligent auxiliary circulating water pipe waste heat boiler, a steam-water mixture leaves the evaporator, enters a boiler barrel at the upper portion and is separated through a steam-water separation device; and water falls in water space in the boiler barrel, enters a down pipe and continues to absorb heat and generate steam, and steam enters the superheater from the upper portion of the boiler barrel and absorbs heat, and then saturated steam is changed into superheated steam. According to the situation that three stages of the steam generation process correspond to three heated surfaces, namely, the coal economizer, the evaporator and the superheater, and if the superheated steam is not needed, only the saturated steam is needed, and the superheater does not need to be installed.
Description
Technical field
The present invention relates to waste heat boiler applied technical field, especially a kind of intelligent auxiliary circulation water pipe waste heat boiler.
Background technology
In the design of waste heat boiler water level control system, control system has needed the Detection of Process Parameters of three parts to realize the automatic control of water level.Meanwhile, in order to solve, large size industrial enterprise centralized control real-time is poor, data processing and transmission slow, the shortcomings such as control decision can not be made to production in good time.Control system also needs on the basis of computer system, to realize the control and management to whole production process.
If waste heat boiler water level control system adopts conventional instrument to control, the instrument that not only system is used is not large for not many, complex structure, enforcement and debugging difficulty, be difficult to the reliability of guarantee system, and difficult carry out communication with control system, realization is still failed in monitoring and in good time decision-making in real time.
In recent years, along with the development of Programmable logic Controller (PLC) technique is perfect, its reliability is high, flexible in configuration, programming is simple and easy, the system installment and debugging cycle is short advantage, and for realizing design that boiler water level controls, debugging provides advantage.Meanwhile, because the control system after configuration is easy to communication, a difficult problem for production process United Dispatching is solved.
Prior art is difficult to the productive life needs meeting people, and for the problems referred to above, the present invention aims to provide a kind of intelligent auxiliary circulation water pipe waste heat boiler.
For realizing this technical purpose, the technical solution used in the present invention is: a kind of intelligent auxiliary circulation water pipe waste heat boiler, comprises boiler chimney, water circulating pump, economizer, evaporimeter, superheater and intelligent controlling device; Described water circulating pump connects the water tank in boiler chimney by pipeline; Described economizer is arranged on boiler side; Described evaporimeter is arranged in the middle of economizer and superheater; Described intelligent controlling device is arranged on boiler side.
As further technical scheme of the present invention: described intelligent controlling device comprises industrial computer, power module, CPU module, adjustment operation valve and electric appliance control box; Described AI module, AO module, DI module and DO module bag are arranged in CPU module; And CPU module and industrial computer control connection, and industrial computer connects display and mouse, keyboard.
As further technical scheme of the present invention: described AO module and DI module respectively with adjustment operation valve control connection, DO model calling Electric Appliance Cabinet control cabinet; Described adjustment operation valve and electric appliance control box all with the waste heat boiler control connection being connected AI module.
Compared with prior art, the present invention has following beneficial effect: this intelligent auxiliary circulation water pipe waste heat boiler, steam water interface is left evaporimeter and enters top drum and be separated by carbonated drink separation equipment, water fall hydrospace in drum enter down-comer continue heat absorption steam, and steam enters superheater from drum top, absorb heat and make saturated vapor become superheated steam.According to the three phases of the process of steaming corresponding three heating surfaces, i.e. economizer, evaporimeter and superheater, if do not need superheated steam, only need saturated vapor, can not superheater be filled.When there being reheated steam, then reheater can be added; Overall structure is simple, novel in design, practical, is easy to promote the use of.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Figure of description 1 ~ 4, in the embodiment of the present invention, a kind of intelligent auxiliary circulation water pipe waste heat boiler, comprises boiler chimney 1, water circulating pump 2, economizer 3, evaporimeter 4, superheater 5 and intelligent controlling device; Described water circulating pump 2 connects the water tank in boiler chimney 1 by pipeline; Described economizer 3 is arranged on boiler side; It is middle with superheater 5 that described evaporimeter 4 is arranged on economizer 3; Described intelligent controlling device is arranged on boiler side.
As further technical scheme of the present invention: described intelligent controlling device comprises industrial computer, power module, CPU module, adjustment operation valve and electric appliance control box; Described AI module, AO module, DI module and DO module bag are arranged in CPU module; And CPU module and industrial computer control connection, and industrial computer connects display and mouse, keyboard.
As further technical scheme of the present invention: described AO module and DI module respectively with adjustment operation valve control connection, DO model calling Electric Appliance Cabinet control cabinet; Described adjustment operation valve and electric appliance control box all with the waste heat boiler control connection being connected AI module.
Action principle of the present invention is: combustion apparatus high-temperature flue gas is out delivered to exhaust-heat boiler inlet through flue, flow through superheater, evaporimeter and economizer again, air is entered finally by chimney, exhaust gas temperature is generally 150 ~ 180 DEG C, and flue-gas temperature drops to from high temperature the heat that exhaust gas temperature discharges and is used for making water become steam.First boiler feedwater enters economizer, and water absorbs heat and is warmed up to and enters drum a little less than the saturation temperature under drum pressure in economizer.Enter after the water of drum mixes with the saturation water in drum, enter evaporimeter along the down-comer below drum and absorb heat and start to steam, normally only become vapour with a part of water, so what flow in steamer is steam water interface; Steam water interface is left evaporimeter and enters top drum and be separated by carbonated drink separation equipment, and water is fallen hydrospace in drum and entered down-comer and continue heat absorption and steam, and steam enters superheater from drum top, absorb heat and make saturated vapor become superheated steam.According to the three phases of the process of steaming corresponding three heating surfaces, i.e. economizer, evaporimeter and superheater, if do not need superheated steam, only need saturated vapor, can not superheater be filled.When there being reheated steam, then reheater can be added.
