Abstract
The utility model discloses a contact condenser for a fuel gas (oil) device, which avoids deficiencies of a dividing wall type heat exchanger and adopts a contact heat exchange between flue gas and cooling water to form the exchanger comprising a shell, a fuel gas inlet mouth and a fuel gas outlet mouth, a cooling water inlet mouth and a cooling water outlet mouth. The fuel gas inlet mouth is arranged on the lower part and the fuel gas outlet mouth is arranged on the upper part while the cooling water inlet mouth is arranged on the upper part and the hot water outlet mouth is arranged on the lower part. The upper part of the cooling water inlet mouth is provided with a liquid distributor with a packing layer positioned on the lower part and the fuel gas inlet mouth is arranged on the lower part of the packing layer. The fuel gas goes from bottom to top while the cooling water flows in a reverse direction, namely, from top to bottom, and the heat transfer and mass transfer go simultaneously. The filling layer is arranged inside to add the heat transfer area so as to prolong the heat transfer time and reduce the temperature of the cooling water even to 30 to 40 DEG C, thus greatly recovering the latent heat of condensation in the vapor of the fuel gas with the heat efficiency reaching 104 to 110 % or even higher. The utility model can be directly used as a final heating surface for the fuel gas (oil) boiler or directly applied to the direct-fired lithium bromide refrigerators, which can save the energy and prevent the pollution to the environment.
Description
Affiliated field: the utility model relates to a kind of condenser, particularly relates to a kind of combustion gas or oil burning installation direct contact condenser.
Background technology: the exhaust gas temperature of present domestic combustion gas (oil) heating boiler and direct-burning type lithium bromide absorption type refrigeration machine is all about 160-260 ℃ or higher.So steam is all drained with gaseous state in the flue gas, the heat of condensation of its water can't reclaim, and the thermal efficiency is (pressing the fuel low heat value calculates) about 88%.The back-end surfaces of existing boiler all is to adopt dividing wall type heat exchanger, and the existence of on-condensible gas such as contained a large amount of nitrogen in the flue gas has influenced the condensation heat transfer of water vapour greatly, so make equipment huge, less economical, it can't improve the thermal efficiency.
Technology contents: for overcoming the low problem of boiler thermal output that prior art exists, the utility model adopts following technical scheme: combustion gas (oil) device direct contact condenser, its composition comprises shell, gas approach, exhanst gas outlet, cooling water inlet, hot water outlet, gas approach below, exhanst gas outlet up, cooling water inlet is up, hot water outlet below, liquid distributor is set below cooling water inlet, is provided with packing layer below the liquid distributor, gas approach is below packing layer.The inventive point of this device just is to have avoided the shortcoming of wall-type heat exchange, has adopted flue gas and the heat exchange of cooling water contact, has improved the thermal efficiency greatly.Flue gas from bottom to top, cooling water is reverse flow from top to bottom, can be effectively the water vapour condensation in the flue gas and catch, again can be the SO in the flue gas
2, SO
2, NO
xBe dissolved in the cooling water, heat transfer and mass transfer take place simultaneously.In establish packing layer to increase heat exchange area, prolong heat-exchange time; In establish the cooling water redistribution device, reducing the wall attachment effect of water, improve the heat exchange effect; Coolant outlet is provided with baffle plate, to eliminate the generation of exit vortex bucket, has avoided wrapping up in the phenomenon of smoking gas; In establish the disc type liquid distribution device, make cooling water finer and closely woven, to improve the thermal efficiency; In establish liquid trap and carry water droplet in the flue gas secretly to prevent to discharge; In establish fluid level controller, add in the cooling water inlet pipeline by automatically controlled reaching with running water, make liquid level go back up to standard state, set fluid-tight overflow mechanism has been avoided the liquid level rising.Because the exhaust gas temperature of this device is low, can be reduced to 30-40 ℃, thus can make this device thermal efficiency bring up to 104-110%, even higher (pressing low heat value).After adopting this device,, help environmental requirement with sulphur and nitrogen oxide in the smoke evacuation are significantly reduced, reduced the corrosion of air-introduced machine blade, because flue-gas temperature reduces, flue gas volume reduces, the air-introduced machine power consumption will be reduced, or save air-introduced machine (when malleation is enough high in the boiler thorax).Used combustion gas (natural gas, liquefied petroleum gas, coal gas) is a kind of spatter property energy, helps environmental protection.Fuel oil (diesel oil, kerosene, heavy oil) should select for use the sulfur-bearing composition few, with minimizing cooling water purification workload, and the operation of this device normal pressure, safe and reliable, simple in structure, be again vertical structure, take up an area of and lack, so the commercial value in its sale is improved greatly.This device can directly be used as the back-end surfaces of combustion gas (oil) boiler and form a kind of New-type boiler-condenser boiler, or is directly used in and is called higher calorific value direct combustion type lithium bromide hot and cold water unit on the direct combustion type lithium bromide hot and cold water unit.The 2nd, can (the direct combustion type bromine cooling machine of oil be supporting, as its back-end surfaces, reduces the cigarette temperature, reclaims its heat, energy savings, reduces cost, prevents the pollution of the environment with combustion gas (fuel oil) boiler in just using or combustion gas.Preresearch estimates, use the economic benefit of this device as follows:
| Inlet flue gas temperature ℃ | 400 | 300 | 250 | 200 | 150 |
| Combustion gas saving amount % | 30-32 | 25-28 | 22-25 | 18-20 | 14-16 |
By the table in as seen, the user is cost-recovering in a short time.
