Boiler waste heat recycling device

Abstract

The invention discloses a boiler waste heat recycling device which comprises a boiler, a smoke opening, a baffle, a pipeline, a water tank, a butt joint, a shell, an elastic plate and a valve. A coilpipe is fixedly installed in the boiler. A positioning shaft is installed in the top end of the smoke opening. A pushing groove is formed in the baffle. The pipeline is fixedly installed at the top end of the smoke opening. A water outlet is formed in the right end of the water tank. The elastic plate is connected with a bottom plate through a spring. A limiting groove is formed in the boiler. A vertical rod is installed in the limiting groove. A second sliding groove is formed in the valve. According to the boiler waste heat recycling device, the baffle is arranged at the top end of the device, a pulling rod is pushed, a pulling rod pushing rod positioning shaft can rotate in an eave opening, thus a pushing rod connecting block drives a rotating arm and a sliding rod to slide in the pushing groove, the baffle is driven to do opening and closing motion, thus an opening and closing gap of the baffle is controlled conveniently, and waste heat in the boiler is conveyed beneficially in a limited manner.

Description

technical field [0001] The invention relates to the technical field of boilers, in particular to a boiler waste heat recovery and utilization device. Background technique [0002] Boiler waste heat recovery and utilization device refers to a device that generates a large amount of heat during use of the boiler, and recovers and utilizes the waste heat generated by the boiler during production. This recovery and utilization is an important direction for improving the energy efficiency of the boiler. In recent years, with the further development of energy-saving emission reduction and energy-efficient utilization, various new energy-saving and emission-reducing equipment emerge in endlessly, and there are countless energy-saving equipment in the boiler field, including a boiler waste heat recovery and utilization device. But the existing boiler waste heat recovery and utilization device also has the following problems: [0003] 1. When the current boiler waste heat recovery a...

Problems solved by technology

[0006] The purpose of the present invention is to provide a boiler waste heat recovery device to solve the problem that the boiler waste heat recovery device on the market cannot control the output of heat in the furnace and is not easy to control the heating effect of cold water. It is easy to waste the waste heat in the furnace, and the direct connection between the pipe and the boiler will cause the waste heat in the furnace to be dissipated faster, which is not conducive to the effective heat preservation effect of the waste heat in the furnace, and is not conducive to energy saving and environmental protection.
