Abstract
The utility model discloses a collateral air-water heat exchanger, which comprises an air chamber, an upper water chamber and a lower water chamber, the upper chamber positioned at the upper part, the upper chamber connected with a water outlet and a steam outlet, the lower water chamber positioned at the lower part, the lower water chamber connected with a water inlet, the air chamber positioned at the central part, the air chamber connected with a smoke inlet, a smoke outlet and an ash clearing mouth, a heat exchange water pipe connected between the upper water chamber and the lower water chamber inside the air chamber, a collateral water pipe connected between the upper water chamber and the lower water chamber outside the air chamber. Through the collateral water pipe the hot water in the upper water chamber can be induced back into the lower water chamber, improving the floating speed in the heat exchange pipe, improving the heat exchanging effect, reducing scaling caused by over heat of the pipe inner wall. Meanwhile the collateral pipe can cool the water in the heat exchanger. The heat exchanger has a large exchange capacity, quick in heat exchange, particularly suitable for smoke-cooling of the intermittent-running burning equipment like a small medical waste incinerator furnace and so on.
Description
Technical field
The utility model relates to a kind of exchange heat with high-temperature gas (as the burnt gas of incinerator) and feeds water to reduce the air-water heat exchanger of gas temperature.
Background technology
Known air-water heat exchanger comprises hydroecium, air chamber and heat exchanging water pipe.Hydroecium is connected with water inlet and delivery port, and air chamber is connected with cleaning door, gas approach and exhanst gas outlet.The heat exchanging water pipe is positioned at air chamber.This air-water heat exchanger is in water inlet and go out water flow velocity when low, can cause the water flow velocity among the heat exchanging water pipe low excessively, and the heat exchange weak effect causes in the heat exchanging water pipe water temperature too high, fouling easily.
Summary of the invention
The purpose of this utility model is that a kind of good effect of heat exchange will be provided, and heat exchanging water pipe's inwall is not easy the by-pass flow formula air-water heat exchanger of fouling.
The purpose of this utility model is achieved in that this heat exchanger is provided with air chamber, upper tank and lower header, upper tank is positioned at top, upper tank is connected with delivery port and steam discharge outlet, lower header is positioned at the bottom, lower header is connected with water inlet, and air chamber is positioned at the middle part, and air chamber is connected with gas approach, exhanst gas outlet and cleaning door, between inner upper tank of air chamber and lower header, be connected with the heat exchanging water pipe, between air chamber outside upper tank and lower header, be connected with the by-pass flow water pipe.
The utility model is connected with the by-pass flow water pipe in the outside of heat exchanger, utilizes the by-pass flow water pipe hot water of upper tank can be drawn and gets back to lower header, improves the water velocity among the heat exchanging water pipe.Particularly when heat exchanger water inlet effluent adopting natural circulation mode (as the top water tank), the by-pass flow water pipe can avoid causing because of the water flow velocity of intaking out is low among the heat exchanging water pipe water flow velocity to spend low problem, thereby improve the water velocity among the heat exchanging water pipe greatly, improve the heat exchange effect, reduce the too high fouling of pipe inner wall water temperature.The water pipe of by-pass flow simultaneously also can play the effect of cooling heat exchanger water temperature.Thermal capacity is big, and the heat transfer rate is fast, is specially adapted to the flue gas cool-down of the combustion apparatus (as small-sized medical wastes incineration stove etc.) of intermitten service, for the further processing of flue gas provides advantage.
