Description

A kind of energy recycling device of carbon black tail gas electricity generation boiler

Technical field

It the utility model is related to a kind of energy recycling device, more particularly to a kind of energy of carbon black tail gas electricity generation boiler Recycle device.

Background technology

Carbon black is a kind of amorphous carbon, light, pine and superfine black powder, surface area are very big, scope from 10 ~ 3000m2/g, be carbonaceous material coal, natural gas, heavy oil, fuel oil etc. under conditions of lack of air through imperfect combustion or by Product obtained by thermal decomposition, in production of carbon black, the steam water interface of carbon black tail gas electricity generation boiler periodical blowdown and continuous blowdown It is directly discharged into and determines in row's flash vessel, the steam water interface of boiler blow-off after dilatation decompression cooling in determining row's flash vessel, mixes by carbonated drink Compound is separated, and the steam after separation is drained into air by steam outlet, and the water after separation by arranging flash vessel sewage draining exit surely Drain into blowdown cooling tank, found in carbon black electricity generation boiler production run, every capacity for arranging flash vessel surely about exists 500Kg/h, pressure at expulsion 0.15MPa, exhaust temperature are 130 DEG C, so not only cause the waste of mass energy, and lead Cause, it is both uneconomical or not environmentally.

The content of the invention

The purpose of this utility model is to provide a kind of energy recycling device of carbon black tail gas electricity generation boiler, by tail gas The energy for determining the discharge of row's flash vessel of electricity generation boiler is recycled, and effectively raises the temperature of boiler demineralized water, every year About 562 tons of standard coal is saved for production of carbon black enterprise.

The utility model is achieved in that it includes carbon black tail gas electricity generation boiler, boiler regular unloading container, steam discharge Receive energy device, drain tank, recovered water pump, desalination water pump, it is characterised in that several carbon black tail gas electricity generation boilers connection boiler is regular Blowdown system, the boiler regular unloading container, steam discharge receive energy device and desalination water pump is sequentially connected, and the steam discharge is received can device Recovered water pump is connected by drain tank.

The boiler regular unloading container, steam discharge, which are received, to be equipped with use in device, drain tank, recovered water pump and desalination water pump In the rock wool of insulation.

It is of the present utility model to have the technical effect that：The effective energy that make use of carbon black tail gas electricity generation boiler to be wasted in working, With manufacturing cost it is low, it is simple in construction, be easy to maintenance, fault rate is low, stable the characteristics of, the noise for reducing plant area is dirty Dye, the service life of equipment is extended, reduce the production cost of production of carbon black enterprise.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model.

In figure, 1, carbon black electricity generation boiler, 2, boiler regular unloading container, 3, steam discharge receive can device, 4, drain tank, 5, return Receive water pump, 6, desalination water pump.

Embodiment

Reference picture 1, the utility model are achieved in that several carbon black tail gas electricity generation boilers 1 connection boiler is periodically arranged Dirty flash vessel 2, the boiler regular unloading container 2, steam discharge receive energy device 3 and desalination water pump 6 is sequentially connected, and the steam discharge receives energy Device 3 connects recovered water pump 5 by drain tank 4, and the boiler regular unloading container, steam discharge are received can device, drain tank, recovered water pump With the rock wool for insulation is equipped with desalination water pump, in use, carbon black tail gas electricity generation boiler discharge steam water interface enter To boiler regular unloading container, in boiler arranges flash vessel surely, steam water interface is separated, and the steam after separation enters Steam discharge is received in energy device, is mixed contact with the demineralized water extracted out by desalination water pump, during mixing contacts, steam heat release, is removed Salt solution absorbs heat, and the demineralized water after heat absorption enters in drain tank 7, then by being extracted out by recovered water pump, demineralized water is delivered into boiler and removed In oxygen device, used for carbon black tail gas electricity generation boiler, and in order to more fully utilize this part energy, expand in boiler periodical blowdown Container, steam discharge receive the rock wool being equipped with energy device, drain tank, recovered water pump and desalination water pump for insulation, effectively prevent heat Loss, the noise pollution of plant area is reduced, extend the service life of equipment, reduce the production cost of production of carbon black enterprise.

Embodiment described above is only that preferred embodiment of the present utility model is described, not to this practicality New scope is defined, and on the premise of the utility model design spirit is not departed from, those of ordinary skill in the art are to this The various modifications and improvement that the technical scheme of utility model is made, the protection of the utility model claims book determination all should be fallen into In the range of.
