CN201339920Y - Coal-saving machine used for conducting waste heat in boiler chimney - Google Patents

Abstract

The utility model discloses a coal-saving machine used for conducting waste heat in boiler chimney, which comprises an outer casing, an inner casing, heat pipes, a flue tube, a water inlet, a flue vent, a water outlet, a circulating backwater pipeline and a lower support. The bottom part of the inner casing is connected to the boiler chimney and the top part is connected by a hooked pipeline; the heat pipes are evenly and spirally arranged on the inner casing; the heat pipes are communicated with the outer casing; circulating water flows between the inner casing and the outer casing; the inner casing is communicated with the outer casing by the circulating back water pipeline; the circulating water between the inner casing and the outer casing can be heated by the high-temperature tail gas in the inner casing; and the heated water can be injected into the boiler from the water outlet or can be used in other occasions needing hot water. The coal-saving machine has the advantages of small volume, high efficiency and convenient installation, can be free from the restriction of room area or installation position and is not be affected by the ambient temperature due to the adoption of insulated packing. The spirally arranged heat pipes enlarge the contact surface for heat transmission, which is high-efficiency and emerging-saving and can heat the circulating water rapidly.

Description

Boiler chimney waste heat thermal conductance economizer

Technical field

The utility model relates to a kind of novel energy-saving environment-friendly equipment, especially a kind of boiler boiler chimney waste heat thermal conductance economizer.

Background technology

Along with the development of producing, human development and utilized a large amount of non-renewable energy resources, day by day accelerate in development, under the energy situation in short supply gradually, the product of energy-conserving and environment-protective is subjected to people's attention more and more, in coal-fired field, the energy-conserving and environment-protective technology with the non-renewable energy resources of this preciousness of coal is the main points of development especially.In application scenarios such as most of heatings, need be the main energy still, and the high-temperature tail gas that conventional boiler produces in the course of the work add the i.e. eliminating of utilization once more with fire coal, the ature of coal utilization rate has only about 50%, has caused the serious wasting of resources.

Summary of the invention

The purpose of this utility model is in order to overcome the deficiencies in the prior art, and the good boiler chimney waste heat thermal conductance economizer of the energy-conserving and environment-protective performance that provides.

The technical solution of the utility model realizes in the following manner:

Boiler chimney waste heat thermal conductance economizer, comprise overcoat, interior cover, heat pipe, chimney, water inlet, exhaust opening, delivery port, circulating backwater pipeline and lower carriage, interior cover bottom has threeway to be connected with boiler flue, the top is connected with the bending pipeline, in put even helical arrangement and heat pipe, heat pipe directly communicates with overcoat, is recirculated water between interior cover and the overcoat, be communicated with the circulating backwater pipeline between overcoat and the overcoat, recirculated water in high-temperature tail gas by interior cover can heat between cover and the overcoat, the water after the heating can directly inject in the stove by delivery port, and perhaps inserting other need be with the occasion of hot water.

Because the utility model adopts above-mentioned material and structure, realized the function of energy-conserving and environment-protective, make the steam coal amount obviously reduce.Its advantage is: boiler chimney waste heat thermal conductance economizer volume is little, and the efficient height is easy for installation, can not be subjected to the restriction of room area and installation site, has adopted the insulation packing, is not subjected to the influence of ambient temperature.The heat pipe of helical arrangement has strengthened the contact-making surface of hot transmission, and is energy-efficient, can make the recirculated water Fast Heating.
