Problems solved by technology
[0004] The purpose of the present invention is to provide a condensing heat exchanger. The specific problem to be solved by the present invention is that most of the existing direct contact condensers do not have a self-cleaning function, or the cleaning system is independent of the device, and the system cannot run synchronously. The self-cleaning system needs to be operated independently when the condenser is shut down, which increases operating costs and reduces work efficiency

Embodiment approach
[0034] As an embodiment of the present invention, the main body of the cleaning mechanism 5 is in the shape of a ring, and a rubber scraper ring 51 is fixedly connected to the outside of the cleaning mechanism 5. The cross-sectional shape of the rubber scraper ring 51 is a 45-degree right-angled triangle whose right angle side coincides with the cylinder body. , where the upper corner is changed to a rounded corner, which can reduce the wear of the rubber scraper ring 51, improve the service life of the rubber scraper ring 51, and avoid the dust accumulation of the rubber scraper ring 51 itself, ensuring the cleaning effect of the rubber scraper ring 51. The lower surface of the rubber scraper ring 51 is fixedly connected with a first guide post 52 and a second guide post 53, and the ends of the first guide post 52 and the second guide post 53 are fixedly connected with a first slider 54 and a second slider 55. The slider 54 and the second slider 55 are matched with the first r...

The invention belongs to the technical field of heat exchangers, and particularly relates to a condensation type heat exchanger which comprises a condenser, a heat exchanger body and a circulating water treatment system, the condenser comprises a cylinder body, a cleaning mechanism, a spraying mechanism, a transmission mechanism, a dust cover and a motor, and a water outlet is formed in the center of the bottom face of the cylinder body. A first air inlet pipeline and a second air inlet pipeline are symmetrically arranged on the side wall, close to the bottom, of the cylinder body, a transmission mechanism cavity is formed in the upper portion of the side wall of the cylinder body, a first exhaust port and a second exhaust port are symmetrically formed in the upper portion of the side wall of the cylinder body, and a transmission mechanism is arranged in the transmission mechanism cavity. The spraying mechanism is slidably connected with a circular hole in the top of the cylinder through a first bearing and a second bearing, the dustproof cover is fixedly connected with the top of the cylinder, and the motor is fixedly connected with the top of the dustproof cover. And by arranging the transmission mechanism and the cleaning mechanism, synchronous operation of the cleaning mechanism and the spraying mechanism is achieved, and high heat transfer efficiency and safety are achieved.
Description
technical field [0001] The invention belongs to the technical field of heat exchangers, and in particular relates to a condensing heat exchanger. Background technique [0002] Generally, the heat exchanger that recovers and utilizes the latent heat of vaporization of water vapor in the flue gas is defined as a condensing heat exchanger. If the exhaust gas temperature of the heat exchanger drops below the saturation temperature, the superheated steam in the flue gas will condense into liquid water to release the latent heat of vaporization, which can be recycled and the heat exchange efficiency can be improved. The condenser that condenses through direct contact between the cooled gas and the cooling liquid or refrigerated liquid is called a direct contact condenser. The gas and liquid are directly mixed and contacted inside the condenser, so as to be as close as possible to the balance of heat transfer and mass transfer. . The Chinese patent with the application number CN2...
