Abstract

The invention discloses an online ash removing device and a heat exchanger with the same. The online ash removing device is mainly composed of traction devices, metal wire ropes, an ash remover, a front-end guider, a rear-end guider and a controller. The metal wire ropes penetrate through the front-end guider and the rear-end guider, and the two ends of the metal wire ropes are each connected withone traction device; the ash remover is fixed to the metal wire ropes and conducts reciprocating movement along with the metal wire ropes between the front-end guider and the rear-end guider; and thecontroller is connected with the traction devices. The online ash removing device and the heat exchanger with the same are high in heat transfer efficiency, adjustable in heat exchange load and highin adaptability, and can achieve online ash removal and ensure long-term operation of equipment.

Description

technical field [0001] The invention relates to an online dust cleaning device for a heat exchange device and a heat exchanger equipped with the online dust cleaning device, in particular to a heat exchanger suitable for a gas phase medium with high dust content and easy fouling in the tube side. Background technique [0002] In the power, petrochemical and chemical industries, there are a large number of heat exchangers with high dust content and easy to scale gas phase medium. The main characteristics are: a. High temperature and low pressure, the temperature of the gas phase medium reaches 1000 ° C, and the pressure is about normal pressure or negative pressure; b. The temperature of the gas outlet needs to be strictly controlled; c. The dust content is high, the heat exchange tube is easy to accumulate dust and scale, and even cause blockage, and the frequency of dust cleaning is high; d. The continuous operation of the device requires online dust removal. [0003] Fouli...
