Energy-saving and environment-friendly transformed heating system for safe non-pressure operation of boilers

Abstract

The invention relates to an energy-saving and environment-friendly transformed heating system for safe non-pressure operation of boilers. The heating system comprises a plurality of the boilers, a water outlet of an internal recycle water supply pipe is connected with a water inlet of an internal recycle heat accumulation tank, the internal recycle heat accumulation tank is provided with a plurality of water outlets, each water outlet of the internal recycle heat accumulation tank is connected with a water inlet of an internal recycle water delivery pipeline through a pipeline which is connected with internal recycle water pumps in series respectively, a water outlet of internal recycle water delivery pipeline is connected with water inlets of heating loops of a plurality of double-pipe heat interchangers respectively, the water inlets of the heating loops of the double-pipe heat interchangers are connected with the water return opening of each boiler through an internal recycle water return pipe, water outlets of heated loops of the double-pipe heat interchangers are connected with a water inlet of a heating water outlet pipe respectively, and the water inlets of the heated loops of the double-pipe heat interchangers are connected with a water outlet of the heating water return pipe respectively. The aim is providing the energy-saving and environment-friendly transformed heating system for the safe non-pressure operation of the boilers, the heating system has the advantages of being very prominent in energy-saving effect, low in operating cost, safe and reliable, small in environment pollution, and better in heating effect.

Description

technical field [0001] The invention relates to an energy-saving and environment-friendly retrofit heating system for a boiler operating safely without pressure. Background technique [0002] In the vast areas of the north, the heating industry is a sensitive industry that is related to the national economy and the people's livelihood and involves thousands of households. Whether energy saving is related to whether energy is saved and whether environmental protection is achieved; heating effect is related to the happiness and stability of thousands of households. The prospect of "energy saving and emission reduction" in the heating industry is quite broad, but it is worth discussing where to start. Judging from the current situation, the light pipe is good at the "end" (metering by household, and now the payment is very controversial. Although heat meters are installed, most areas still continue the tradition of paying fees by area, which will cause greater waste. For examp...

Problems solved by technology

Many boilers are not designed to consider their own condensate discharge, which leads to internal corrosion of the boiler; the design of the boiler room does not consider the discharge of condensate from flue gas. The condensate flows into the boiler and cannot be removed in time, resulting in some boiler components (especially the rear smoke box) The corrosion is serious, resulting in damage to the pressure-bearing parts, which greatly shortens the service life of the boiler, and
