Kitchen range waste heat recovering energy-conserving system and water-level controlling heat insulation device

Abstract

The invention discloses an exhaust-heat recovery energy-saving system of the cooking range to get the hot water quickly. It includes the heat exchanger, the water tank, the heat insulating hot water tank, the water level control heat insulation system and the steam conduit. The water tank is connected to the water resource by the inlet pipe and connected to the heat exchanger. The water level control heat insulation system is set on the outlet pipe. The heat exchanger is connected to the hot water tank by the hot water pipe which is set with the temperature sensor, the magnetic valve and the hot water flow control valve. The water level control device is below the water tank and control the water level which is higher than the heat exchanger and the hot water tank.

Description

technical field [0001] The invention relates to a stove waste heat recovery and energy saving system, and a water level control heat insulation device used in the stove waste heat recovery and energy saving system. Background technique [0002] In large catering places such as hotels and guesthouses, multi-burner stoves are required to work for a long time. Generally, the stoves have a large amount of heat, which causes a large amount of heat to be discharged through the flue on the stove, resulting in It is a waste of energy, and it also makes the temperature of the kitchen unbearably high; on the other hand, a large amount of hot / boiling water also needs to be boiled with a stove or electricity. If the waste heat from the stove can be used to heat / boil water, it will not only save energy, but also cool down the kitchen and make the staff more comfortable. In this regard, the applicant submitted an application for a patent for invention on August 24, 2004 (the application ...
