Abstract
The invention discloses a hot water heat exchanger by means of heatable brick bed flue gas and belongs to the field of flue gas waste heat utilization. The hot water heat exchanger comprises a water inlet connection pipe, a water outlet connection pipe, heat exchange tubes, a smoke inlet, a back plate, a flue gas flow guide plate and a pipe plate. The water inlet connection pipe and the water outlet connection pipe are semicircular, the heat exchange tubes are in a snake shape and are arranged in a radial mode along the water inlet connection pipe and the water outlet connection pipe and are vertically installed, the two ends of the heat exchange tubes are connected with the water inlet connection pipe and the water outlet connection pipe respectively, and heat exchange fluid forms a same-course flow mode in the heat exchange tubes. The flowing direction of flue gas is opposite to the flowing direction of the fluid in the heat exchange tubes, the pipe plate is located on the lower portions of the heat exchange tubes and is semi-annular, the connection mode between the pipe plate and the heat exchange tubes is welding, and the flue gas flow guide plate is located in the smoke inlet. The hot water heat exchanger has the advantages of reducing the temperature of the head of a heatable brick bed, improving evenness of the temperature of the heatable brick bed surface and providing heating and domestic hot water for users by means of flue gas heat energy.
Description
Technical field
The invention belongs to fume afterheat and utilize field, relating to a kind of for reducing warmer end of a kang temperature, utilize a heatable brick bed road flue gas heat to provide the heat transmission equipment of heating and domestic hot-water for user.
Background technology
Heated kang is the heating facility that northern country is conventional, the heating of stove a heatable brick bed is a kind of mode of energy cascade utilization, traditional heated kang is generally be built into moulded pottery not yet put in a kiln to bake and fragment of brick, inside establish flue, stove is thermal source, a heatable brick bed is heat storage, the flue gas that stove burning straw and bavin firewood produce is by outside the flue discharge chamber of a heatable brick bed, flue gas is in the process flowing through flue, a heatable brick bed body is heated by the mode of convection current and radiation, because the warmer end of a kang is directly connected with stove, therefore a heatable brick bed surface temperature in position, the warmer end of a kang is apparently higher than the temperature in a heatable brick bed tail a heatable brick bed face, cause whole a heatable brick bed surface temperature uniformity extreme difference, resident family in use comfort level is poor, and because the temperature of flue gas is higher, the heat of flue gas fails to be absorbed by a heatable brick bed plate the loss that finally also result in flue gas heat completely.For this reason, how to improve the uniformity of a heatable brick bed temperature, the utilization rate improving smoke heat energy has great importance to rural area stove a heatable brick bed heating system.
Summary of the invention
The technical problem to be solved in the present invention is to provide the heat transmission equipment making full use of a heatable brick bed road fume afterheat, to reduce warmer end of a kang temperature, to improve a heatable brick bed surface temperature uniformity, simultaneously for user provides heating and domestic hot-water.
Technical scheme of the present invention is as follows:
A heatable brick bed road of the present invention fume hot-water heat exchanger primarily of water inlet union, water outlet union, heat exchanger tube, enter mouth, backboard, smoke deflector and tube sheet composition, structural representation is as shown in accompanying drawing 1 ~ accompanying drawing 5.Water inlet union and water outlet union are semi-circular, be positioned at the top of heat exchanger and be arranged on sustained height, heat exchanger tube is snake type, along water inlet union and water outlet union radial arrangement, vertical installation, two ends are connected with water inlet union and water outlet union respectively, water outlet union is near entering mouth, water inlet union is positioned at opposite side, cold water enters into water union from one end of water inlet union, heat after water inlet union, heat exchanger tube and water outlet union, hot water flows out from the other end that water outlet union is relative with water inlet, and heat exchanging fluid forms same journey flow pattern in heat exchanger tube; Flow of flue gas direction and fluid flow direction in heat exchanger tube is contrary; Tube sheet is semi-annular, is positioned at the bottom of heat exchanger tube, and level is installed, and the connected mode between tube sheet with heat exchanger tube is for welding; Heat exchanger backboard is connected with the two ends of semi-circular water inlet union and water outlet union, vertically installs; Smoke deflector is positioned at into mouth.
The heat exchanger tube of a heatable brick bed road of the present invention fume hot-water heat exchanger both can be copper pipe, also can steel pipe, can arrange the fin vertically arranged outside heat exchanger tube.
The smoke deflector of a heatable brick bed road of the present invention fume hot-water heat exchanger both can be plane form, also can be arc.
The backboard of a heatable brick bed road of the present invention fume hot-water heat exchanger both can be steel plate, also can be iron plate.
Present invention reduces warmer end of a kang temperature, improve the uniformity of a heatable brick bed surface temperature.Smoke heat energy can be utilized to provide heating and domestic hot-water for user, and apparatus structure is simple, easily processes, with low cost, is easy to promote.
