Problems solved by technology

[0004] The above existing technical solutions have the following defects: since the return water of the heating network will contain impurities such as metal oxides, crushed sand or sediment, when the water flows in the tube bundle, the impurities will cause the tube bundle to block; Impurities deteriorate the water quality, making it easy to scale on the inner wall of the tube bundle, thereby reducing the heat exchange efficiency; when the tube bundle is blocked or there is too much scaling, it is necessary to stop the operation of the heater and use special cleaning equipment to clean the tube bundle , reducing the effective utilization time of the heater, inevitably affecting the hot water production efficiency

Abstract

The invention relates to a heater for heating network. The heater for heating network comprises a shell and a front end pipe box and a rear end pipe box; the front end pipe box and the rear end pipe box are arranged at the two ends of the shell; pipe bundles are arranged in the shell; a partition plate is arranged in the front end pipe box along the axis of the shell and the front end pipe box isdivided into an upper water inlet cavity and a lower water outlet cavity; the upper end of the water inlet cavity communicates with a water inlet pipe connecting pipe; the lower end of the water outlet cavity communicates with a water outlet pipe connecting pipe; the upper end of the shell is provided a steam inlet connecting pipe; the lower end of the shell is provided with a drain outlet connecting pipe; a filter screen is arranged in the water inlet pipe connecting pipe; the filter screen is cylindrical with an opening arranging at the upper end; the upper end of the filter screen is rotationally connected in the water inlet pipe connecting pipe and the lower end of the filter screen extends into the water inlet cavity; and a driving part for driving the filter screen to rotate is arranged in the water inlet pipe connecting pipe. The heater for heating network has the effects that the water medium is filtered, impurities are reduced from entering the pipe bundles, the probability ofblockage and scaling of the pipe bundles is reduced so that the cleaning times are further reduced, the utilization efficiency of the heater is guaranteed to the greatest extent, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of boiler heating, in particular to a heating network heater. Background technique [0002] At present, the heat network heater is the key equipment of the heat network system and one of the main auxiliary equipment of the thermal power plant. Circulating water to meet heating user requirements. [0003] The existing authorized announcement is CN103868379B, which discloses a heat-mixing heat network heater, including a left tube box and a right tube box, and the tube plate shell arranged in the middle of the left tube box and the right tube box is welded, and is arranged on the tube plate The tube bundle inside the shell is welded, and the tube bundle is divided into three areas, namely the low resistance area near the upper and lower ends of the shell, and the high resistance area near the center line of the tube bundle, which is set between the high resistance area and the low resistance area. The transi...
