Abstract

The utility model belongs to an energy-efficient device for treating waste liquid and/or waste gas and particularly provides an incinerator for waste liquid and/or waste gas, which comprises an incinerator body, a hearth, a liquid inlet and/or a gas inlet of the incinerator body, a combustor perpendicular to the liquid inlet and/or gas inlet thereof, and a smoke outlet and an ash outlet of the incinerator, wherein the incinerator body and the hearth have a Venturi structure; and the waste liquid and/or waste gas passes through a high-temperature layer generated by burning fuel at a uniform rate after being subjected to flow-conditioning by the Venturi structure of the hearth, thus achieving the purpose of complete incineration and ensuring that the thermal efficiency of the incinerator is high in combustion. The device of the utility model constitutes a single unit for the incineration of waste liquid or waste gas or a dual-purpose incinerator for incinerating waste liquid and waste gas at the same time.

Description

A kind of waste liquid and/or waste gas combustion furnace

Technical field

The utility model belongs to waste liquid and/or exhaust-gas treatment and energy-saving equipment, and especially a kind of waste liquid and/or waste gas combustion furnace, this incinerator are can burn separately or the incinerator of mixed burning waste liquid, waste gas.

Background technology

Waste liquid and/or waste gas that industries such as organic chemical industry, medical agricultural chemicals, electronics, timber, external coating produce in process of production take incinerating method to handle usually.Chinese patent application file 01221949.5 discloses " CIU of a kind of organic liquid waste and waste gas ", its cyclone type incinerator is by waste liquid (waste gas) nozzle, upright cylinder burner hearth, secondary wind house steward, the coal-fired combustion-supporting nozzle, the reverse inlet tube of air, smoke outlet tube, secondary wind is inlet tube forward, heat insulation layer, temperature tube, igniting formations such as combustion-supporting nozzle of fuel oil and slag notch, the evaporation of before incinerator, being furnished with corresponding waste liquid, the desalination multi-effect evaporator, back corresponding heat recovery boiler of hot gas and the gas washing, purifying equipment of burning that reclaims is arranged thereafter, the deficiency that this incinerator exists is: 1, burner hearth is a cylindrical shape, the part waste liquid and/or the waste gas that enter burner hearth can move along the furnace wall, heated short circuit phenomenon can take place in this part waste liquid and/or waste gas, influences the treatment effeciency of equipment; 2, waste liquid, exhaust gas inlet are all used same nozzle, and the waste liquid particle that enters body of heater is bigger, can't scatter, and the gas that enters with the gas column form, power is big, very easily breaks through the combustion high temperature district, thereby the burning of waste liquid and waste gas is difficult to fully; 3, there is not energy-conservation facility in the body of heater, energy consumption is higher.

Summary of the invention

The utility model in order to overcome above-mentioned deficiency, provides a kind of waste liquid and/or waste gas combustion furnace just, and waste liquid and waste gas fully, are fully burnt and energy-saving safety.

The utility model main innovation is that burner hearth of the furnace body adopts Venturi tube structure, is sprayed on the waste liquid of expansion segment before the burner hearth venturi and/or waste gas and can rebounds and fall after rise to the venturi contraction section, avoids the generation of always moving along the furnace wall of waste liquid and/or waste gas to be heated short circuit.

Specifically be achieved like this:

A kind of waste liquid and/or waste gas combustion furnace comprise body of heater and burner hearth of the furnace body, inlet and/or air inlet, the burner with the vertical laying of inlet and/or air inlet, the outlet flue that is arranged on furnace outlet and ash hole, and burner hearth of the furnace body is a Venturi tube structure.

Described burner arrangement is on the contraction section of the middle part of burner hearth of the furnace body Venturi tube structure.

Described inlet, air inlet are set up separately, and inlet is the dual-flow atomizer import, and air inlet is the import of eddy flow plate gas distributor.

The import of described eddy flow plate gas distributor is monotubular eddy flow plate or sleeve eddy flow plate or baffle arrangement.

The exit of described burner hearth of the furnace body is provided with Heat Storing Wall.

Described Heat Storing Wall is the honeycomb that the high heat capacity heat-storing material is made.

Described high heat capacity heat-storing material is mullite or cordierite or zirconia.

Lay with feed liquor and/or air inlet are vertical with burner because of heating, can form the high temperature cross section, waste liquid, waste gas evenly by heat zone, are heated equably.In order to strengthen the function in high temperature cross section, this equipment on the contraction section of the middle part of venturi burner hearth, can make burner arrangement waste liquid in the body of heater, waste gas and all can is fully burned or be heated by this thermal-flame district by the waste liquid of expansion segment furnace wall bounce-back before the venturi burner hearth, waste gas.

Inlet and air inlet on the utility model body of heater are set up separately, inlet is the dual-flow atomizer import, waste liquid is fully atomized, air inlet adopts the import of eddy flow plate gas distributor, can make gas with the plug flow mode air inlet, waste gas can pass through vertical thermal-flame layer lentamente, equably, and owing to the problem of the excessive formation low-temperature space of local power, the import of this eddy flow plate gas distributor can be adopted monotubular, sleeve eddy flow plate or baffle arrangement when avoiding the gas column intake method.

In order to increase the effective time of staying of waste liquid waste gas in the burner hearth high-temperature region, this equipment is provided with Heat Storing Wall to increase high-temperature space in the exit of burner hearth of the furnace body, Heat Storing Wall is a honeycomb, adopt high heat capacity heat-storing material such as mullite, cordierite, zirconia etc., the interpolation of Heat Storing Wall has greatly improved the thermal efficiency of body of heater, has obviously improved the energy-conserving action of equipment.

In order to improve the security of this equipment, body of heater is provided with explosion proof door, and the exhaust pipe that joins with air inlet is provided with spark arrester, in the time of effectively preventing maloperation to the infringement of people and equipment.

The utility model body of heater has wearing layer, thermal insulation layer and outer steel structure to constitute from the inside to the outside.

The beneficial effects of the utility model are:

The utility model is by changing burner hearth into Venturi tube structure, feed liquor/air inlet independent being provided with, setting up Heat Storing Wall in the burner hearth, waste liquid is mixed after atomizing and by the waste gas that the waste gas distributor enters, through heat zone that produces by fuel combustion equably after the rectification of Venturi tube structure on the body of heater and the high-temperature space that forms by the high-temperature heat accumulation wall, reach the purpose of burning fully.The high-temperature flue gas that incinerator of the present utility model produces can reclaim heat through heat economizer and residual neat recovering system, make flue gas cool-down after the chimney atmosphere that enters up to standard, waste gas after preheating has improved the furnace temperature that advances of waste gas, reduce fuel quantity, increase the burning thermal efficiency of stove, the utility model both can be independent waste liquid, burned waste gas equipment, also can be the mixed type incinerator that burns waste liquid waste gas simultaneously.
