Abstract
The utility model discloses a gas-liquid heat exchanger, which comprises a box body (1), wherein the front and the back of the box body (1) are open; radiating pipes (2) are arranged in the box body (1) and are arranged along the left side and the right side of the box body (1) in a snakelike form; and the liquid inlet end and the liquid outlet end of each radiating pipe (2) extend out of the side face of the box body (1). In the utility model, carbon dioxide (CO2) absorption liquid flows in a heat exchange tube to absorb heat; and tail gas flows outside the heat exchange tube and inside the box body and releases heat, so that waste heat of waste gas is utilized effectively, the process requirement on heating of the CO2 absorption liquid is met, any external heat source is not needed for heating, energy is saved, the environment is protected and cost is lowered.
Description
Technical field
The utility model belongs to chemical industry equipment, relates to a kind of heat exchanger of gas-liquid two-phase heat-shift specifically.
Background technology
At present, from the waste gas that combustion of natural gas generates with CO
2Purify, the method for normal employing is a chemical absorption method, and its operation principle is: adopt solution (the MEA aqueous solution) to generating the CO in the gas at normal temperatures
2Absorb, at high temperature with CO
2Discharge, to reach CO
2The purpose of purifying.In absorption liquid (MEA) cyclic process, need absorption liquid is heated, the heating means of absorption liquid are to adopt boiler for steam heated or two kinds of methods of employing electrical heating basically now, these two kinds of methods all need consume a large amount of energy.
The utility model content
The purpose of this utility model is to provide a kind of heat of waste gas that utilizes to CO
2Absorption liquid heats the gas-liquid heat-exchange that reaches technological requirement.
The technical solution of the utility model is as follows: a kind of gas-liquid heat-exchange, comprise casing, its key is: have the flue gas interface before and after the described casing, in this casing radiating tube is housed, this radiating tube is snakelike along the casing left and right sides arranges, and the liquid feeding end of described radiating tube and outlet end all pass from the casing side.In the running, waste gas is by uncovered process casing before and after the casing, CO
2Absorption liquid flows through through radiating tube, and radiating tube carries out heat exchange in waste gas and the casing, the CO in the radiating tube
2After absorption liquid absorbed heat, temperature raise and reaches technological requirement.
Radiating tube and fin are housed in the above-mentioned casing, and described fin vertically distributes in casing.Fin setting has increased heat exchange area, considers in being provided with to contain acidic materials in the tail gas, steel is had corrosion, so heat exchange tube material is selected stainless steel for use.Heat exchanger tube adopts the multilayer cross arrangement, and liquid feeding end is by the outlet of tail gas, and outlet end adopts reverse heat-exchange by the import of tail gas, to increase heat transfer temperature difference.
Above-mentioned wall box is that about two-layered steel plates and the middle thermal insulation board that is provided with are formed.Make casing have the effect of energy-saving heat preserving.
Above-mentioned bottom half is equipped with drip tray, and this drip tray bottom is provided with drainpipe.So that in heat exchanging process, a large amount of steam that tail gas produces condense into water, collect in drip tray and discharge smoothly.The material selection corrosion resistant plate of water pond is made in the design.
Beneficial effect: the utility model CO
2Absorption liquid flows in heat exchanger tube, absorbs heat; And tail gas flows outside heat exchanger tube, in the casing, and release heat has effectively been utilized the waste heat of waste gas, comes CO
2Absorption liquid heats and reaches technological requirement, no longer needs external thermal source heating, and energy-conserving and environment-protective have also reduced cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the upward view of Fig. 1.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1 and Figure 2, a kind of gas-liquid heat-exchange mainly is made up of casing 1, radiating tube 2, fin 3, drip tray 4 and drainpipe 5, and casing 1 front and back are uncovered shape, forms interface 1a, is provided with radiating tube 2, fin 3, drip tray 4 and drainpipe 5 in the casing 1.This radiating tube 2 is snakelike along casing 1 left and right sides arranges, and the liquid feeding end of described radiating tube 2 and outlet end all pass from casing 1 left surface.Described fin 3 vertically distributes in casing 1.Drip tray 4 is equipped with in casing 1 bottom, and these drip tray 4 bottoms are provided with drainpipe 5.Described casing 1 sidewall is that about two-layered steel plates and the middle thermal insulation board that is provided with are formed.
Operation principle: waste gas is from uncovered the entering in casing 1 front, then from the uncovered discharge in casing 1 back, CO
2Absorption liquid enters from radiating tube 2 liquid feeding ends, flows out from radiating tube 2 outlet ends.CO
2The heat exchange in casing 1 of absorption liquid and waste gas, liquid feeding end is uncovered by casing 1 back, and outlet end is uncovered by casing 1 front, forms reverse heat-exchange.
Although above structure is described the preferred embodiments of the present invention in conjunction with the accompanying drawings; but the invention is not restricted to the above-mentioned specific embodiment; the above-mentioned specific embodiment only is schematic rather than determinate; those of ordinary skill in the art is under enlightenment of the present invention; under the prerequisite of aim of the present invention and claim; can make multiple similar expression; as change heat dissipation channel shape mode; type kind of change cooling agent or the like, such conversion all falls within the protection domain of the present utility model.
