Description

A kind of novel mixed boiler waste heat recovery system

Technical field

The present invention relates to boiler afterheat recovery technologies, belong to heat recovery technology field.

Background technology

At present in terms of boiler afterheat recycling, heat recovery heat exchanger mostly uses greatly level-one reclaimer, predominantly directly Contact heat exchanger and indirect contact heat exchanger.But the fact is that using level-one recycling heat exchanger, often effect is less desirable, Amount of heat in flue gas cannot be recycled effectively, caused a large amount of waste heats to be lost to air aerial, not only caused serious ring Border is polluted, and global air temperature warming process has been aggravated, and even more because amount of heat cannot be recycled effectively, wastes a performance Source.Besides traditional waste heat recovery apparatus structure is complex, especially in traditional multistage reclaimer in cooling water outlet It is increasingly complex to locate structure, for the problem present on, the present invention proposes a kind of new pipe heat exchanger and fountain heat exchange The heat exchanger that device mixes, to be classified the heat in recovered flue gas jointly.Heat that can effectively in recovered flue gas.

It is existing to solve the technical problem to be solved in the present invention is to provide a kind of novel mixed boiler waste heat recovery system It is existing that insufficient and complicated problem is recycled to flue gas heat.The device is exchanged heat by pipe heat exchanger and fountain Device is connected, and by the way of two-stage cooling, can not only effectively be realized the reduction of exhaust gas temperature, be improved the waste heat recovery of boiler Efficiency, moreover it is possible to improve the utilization rate of the energy, the ultimate purpose of environmental protection energy saving to reach.

Invention content

In order to achieve the above objectives, the present invention is achieved by the following scheme.

A kind of novel mixed formula boiler waste heat recovery system, which is characterized in that including:Pipe heat exchanger and pipe heat exchanger The spray chamber connected by flue, the pipe heat exchanger upper left quarter are equipped with gas inlet, flue gas are equipped on the right side of the spray chamber Outlet, spray chamber top are equipped with nozzle, and the pipe heat exchanger outlet pipe and spray chamber outlet pipe converge at one, recovered heat Cold water after amount flows into boiler again.

As with improvement, bottom is designed in sloping inwardly in the spray chamber of the spray-type heat exchanger, in order to spray chamber Interior water can preferably flow into spray-type heat exchanger outlet pipe.

As with improvement, exhaust gases passes are equipped between the pipe heat exchanger and spray-type heat exchanger, in order to from flue gas Spray chamber is led directly to after pipe heat exchanger, by the heat in two-stage blended absorbent flue gas.

As with improvement, a kind of novel mixed boiler waste heat recovery system, flue gas first passes through pipe heat exchanger, so Water direct contact heat-exchanging under directly being sprayed afterwards with nozzle using spray chamber, the purpose for first passing through pipe heat exchanger be prevent through Smoke moisture increases after crossing spray-type heat exchanger, reduces the extent of corrosion to pipe heat exchanger material.

As with improvement, the spray-type heat exchanger exhanst gas outlet is equipped with air-introduced machine, in order to which flue gas can be unobstructed The entire heat-exchanger rig of circulation.

As with improvement, the water outlet of lower left quarter connects the water outlet of pipe heat exchanger in the spray-type heat exchanger spray chamber Check valve is equipped at mouthful.Only allow to spray in indoor water inflow main pipeline, prevents aqueous reflux from returning spray chamber.

Compared with prior art, the available effect of the present invention is:

The present invention recycles the heat in flue gas using pipe heat exchanger and spray-type heat exchanger two-stage heat exchanger, can be effective The temperature for reducing flue gas partially absorbs the harmful substance in flue gas especially by spray chamber, can effectively reduce cigarette The concentration of harmful substance, not only saves energy in gas, also protects environment, and to energy shortage now, environmental pollution is increasingly tight Play the role of again great.Outlet pipe by spraying indoor outlet pipe and pipe heat exchanger converges to the design at one, Internal structure is greatly simplified, material and cost have been saved.

Description of the drawings

Explanation and specific embodiment are described in further details the present invention below in conjunction with the accompanying drawings

Fig. 1 is a kind of novel mixed system structure diagram of invention;

6 exhanst gas outlet 7 of channel 4 nozzle, 5 spray chamber of 1 gas inlet, 2 pipe heat exchanger, 3 pipe heat exchanger and spray chamber 10 total outlet pipe of spray chamber outlet pipe 8 pipe heat exchanger outlet pipe, 9 check valve, 11 pipe heat exchanger water inlet pipe.

Specific implementation mode

Embodiment of the present invention is described in detail below in conjunction with embodiment, but those skilled in the art will It will be appreciated that the following example is only limitted to patent of the present invention, and it is not construed as the scope of the present invention.

Referring to Fig.1, a kind of novel mixed boiler waste heat recovery system provided by the invention, which is characterized in that including:Pipe Formula heat exchanger 2, the spray chamber 5 being connect by flue 3 with pipe heat exchanger, the pipe heat exchanger upper left quarter are equipped with gas inlet 1, the spray chamber right side is equipped with exhanst gas outlet 6, and nozzle 4 is equipped at the top of spray chamber, and the pipe heat exchanger is equipped with water inlet pipe 11 The pipe heat exchanger outlet pipe 8 and spray chamber outlet pipe 8 converge at one, and being equipped in meet only allows water from spray chamber stream To the check valve 9 of total outlet pipe 10, the water after hybrid waste-heat recovery device flows into boiler.

Flue gas enters a kind of novel mixed boiler waste heat recovery system from gas inlet 1 in the embodiment above, initially enters Pipe heat exchanger 2, flue gas enter spray chamber 5 through the channel 3 of pipe heat exchanger and spray chamber, most afterwards should through the outflow of exhanst gas outlet 6 Device.A part of cold water enters pipe type heat transfer through pipe heat exchanger water inlet pipe 11 while flue gas constantly flows through the heat-exchanger rig Device 2 has obtained the partial heat in flue gas by pipe heat exchanger cold water, is most discharged afterwards through pipe heat exchanger outlet pipe 8, one Cold water is divided to be sprayed onto in spray chamber 5 through nozzle 4, cold water passes through is in direct contact acquisition heat with the flue gas in spray chamber, then passes through Spray chamber outlet pipe 7 is converged by check valve 9 and the water from pipe heat exchanger, most flows to boiler through total outlet pipe 10 afterwards.
