Description
Technical field
The utility model relates to a kind of boiler blow-off waste heat recovery apparatus.
Background technology
Existing boiler blow-off waste heat recovery is to utilize the platoon flash vessel to reclaim exhaust steam to utilize (belonging to pressure vessel and equipment) again, and the spent hot water directly effluxes; After flash vessel buffering and noise reduction are arranged in utilization surely, directly emptying after the flash distillation, the spent hot water effluxes.In operate as normal, just a spot of exhaust steam has been reclaimed, most of heat energy has all wasted, and is unfavorable for energy-conservation.
The utility model content
The utility model technical issues that need to address provide a kind of simple in structure, boiler blow-off heat recovery rate height, can carry out deciding the boiler blow-off waste heat recovery apparatus of row's platoon waste heat recovery simultaneously to many boilers.
For addressing the above problem, technical solution adopted in the utility model is: a kind of boiler blow-off waste heat recovery apparatus, comprise tank body, be positioned at boiler blow-off sewage import on the tank body, wastewater outlet and flash gas outlet, be positioned at vapor-liquid separation plate, swirling flow conduit, the heat exchanger of tank interior, wherein the swirling flow conduit connects the sewage import, heat exchanger connects the demineralized water that is positioned on the tank body and imports and exports, wastewater outlet is positioned at tank base, the flash gas outlet is positioned at tank body top, external asymmetric heat exchanger.
Described sewage import comprises that boiler decides sewer import and the import of boiler platoon sewage.
Described vapor-liquid separation plate is two, lays respectively at the first half and the Lower Half of tank body, is provided with a swirling chamber between the two vapor-liquid separation plates, and the swirling flow conduit is arranged in swirling chamber.
Have the maintenance inlet that overhauls usefulness for the workman on the described tank body.
Be provided with the liquid level gauge of liquid level in the control tank body in the described tank body.
Described asymmetric heat exchanger exit is connected with evacuation port, is connected to wastewater discharge pipe by pipeline simultaneously.
Described heat exchanger can be any one in board-like, helix tube, floating coiled pipe, tubulation, heat pipe, the vacuum heat exchanger.
Adopt the beneficial effect that technique scheme produced to be: this novel will row surely with platoon unites two into one, connect many boilers simultaneously, utilize injection and swirling flow principle to make the more fully flash distillation of waste water of access arrangement, reduced the sewage water discharge temperature, flash-off steam utilizes unique asymmetric module heat exchanger to absorb heat energy, the water reuse spiral tube exchanger fully absorbs residue heat energy, improved efficiency of utilization, reduced production cost and maintenance cost, eliminated the white pollution of secondary flash distillation, equipment making is a vessels not under pressure, thoroughly solved the limitation of existing equipment, make simply, take up an area of and lack, the making maintenance cost is low.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model sewage import partial enlarged drawing.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
As Fig. 1, shown in 2, this novel device comprises tank body 1, on tank body 1, be provided with the sewage import, wastewater outlet, the flash gas outlet, demineralized water import 4, demineralized water outlet 5, maintenance inlet 10, wastewater outlet connects wastewater discharge pipe 6, flash gas exports external asymmetric heat exchanger 13 1 ends, asymmetric heat exchanger 13 other ends run in and eat dishes without rice or wine 12, be connected with wastewater discharge pipe 6 by pipeline 9 simultaneously, at tank body 1 internal softening water entrance 4, spiral tube exchanger is housed between 5, the first half and Lower Half in tank body 1 inside are provided with two vapor-liquid separation plates 11, between two vapor-liquid separation plates 11, be provided with swirling chamber 8, be provided with the swirling flow conduit in the swirling chamber 8, the swirling flow conduit is connected with the sewage import, what also be provided with the control liquid level in the tank body turns over magnetic liquid level gauge 7, described sewage import comprises that three boilers decide sewer import 3 and three boiler platoon sewage import 2, and described spiral tube exchanger can also be from board-like, floating coiled pipe, tubulation, heat pipe, choose any one kind of them in the vacuum heat exchanger.
This novel device equipment drainage utilization injection and swirling flow principle, boiler blow-off sewage passes through sewage import 2 successively, 3, diversion chamber 14, mix relief chamber 15, after the swirling flow conduit enters tank body 1, (the swirling flow conduit is connected on the swirling flow duct entry 16 that mixes relief chamber 15), by swirling flow conduit and vapor-liquid separation plate 11 gas-vapor mix is as much as possible fully separated under the low pressure situation again, because the pressure of flash-off steam is very low, most of on-sites can not utilize fully to the secondary flash-off steam, but by this method, make flash-off steam pass through asymmetric module heat exchanger 13 heat energy is fully absorbed, a small amount of hot gas that reclaims fully is not by evacuation port 12 emptyings; The spent hot water utilizes the spiral tube exchanger of producing by U.S.'s state-of-the-art technology, the heat absorption in the waste water, go out from demineralized water outlet 5 again after being heated water and entering and enter the deoxygenation water tank from demineralized water import 4, finish the heat energy circulation, improve the heat energy utilization rate, waste water directly effluxes from waste water discharge opening.During work, utilize and turn over the height that magnetic liquid level gauge 7 is controlled liquid level in the tank body, temperature at discharging condensate is reduced as much as possible.Maintenance hand-hole 10 is to enter the passage that tank body keeps in repair when maintenance.
There are many boilers in general factory, and fixed row and platoon can be concentrated from 2,3 interface parallel connections and enter this equipment.During operation, appoint that deciding row will carry out blowdown orderly, platoon can with the same operation originally.Under the situation that two 35 tons of boilers and 65 tons of boiler move simultaneously, the outer draining water temperature of equipment can drop to about 35 ℃, and evacuated tube emptying temperature can drop to about 70 ℃, improves the utilization rate of whole boiler 0.5%.This equipment is the above boiler of 3-5 platform in parallel simultaneously, saves space and investment.
