Description

Composite energy-saving water heating kang for rural areas in north

The technical field is as follows:

the utility model relates to a rural area combined type energy-conserving hot water warm kang in north.

Background art:

northern areas are long in winter and severe cold time, houses in rural areas are distributed scattered, large-scale central heating equipment is not easy to build, and heated kang or electric heated kang are widely used for meeting heating requirements. However, most of the fuels of heated brick beds are coal, wood, firewood and the like, a large amount of coal mining and tree felling can damage the existing resources, smoke and dust generated during combustion can pollute the environment, resource waste can be caused due to insufficient combustion, and the generated carbon monoxide can also influence the health of human bodies. The electric heating kang has the phenomena of power consumption and electric leakage, and electromagnetic wave radiation can also have certain influence on the human body. China is a large food country and the yield of straws is high. In the face of a large amount of straws, the treatment mode of common people is mostly open-air incineration. The PM2.5 content in the air can be increased rapidly by incineration, and the generated toxic and harmful substances can threaten the health of people and other organisms. The burning of straw in the field can also destroy the soil structure, resulting in the reduction of the quality of the field. But a large amount of straws are really good heating materials for the kang body. The rural areas also have the phenomena of poor natural conditions, low economy and low income of farmers, and the water heating kang popular in the market at present has higher manufacturing cost and can not meet the requirements of most people.

At present, people research a water heating kang. The water heating kang is composed of a kang plate and a controller. The kang plate is made of an aluminum-plated zinc plate and a polyurethane foaming material, a PERT ground heating pipe is embedded in the kang plate, the controller adopts PTC water and electricity separated heating, an ultra-silent water pump circulates, and a constant-temperature intelligent control system is used as a driving end; the controller is connected with the pipeline fittings of the hot kang plate for use, and water is heated by the PTC pipeline heater and is conveyed into the hot kang plate for heat transfer. The water-heating kang is safer in water-electricity separation heating, only has a water pipe in the water-heating kang, does not lay electric wires, electric heating wires and the like, and is energy-saving and environment-friendly.

In the actual popularization process, most rural natural conditions are poor, the economic foundation is weak, the pure income of farmers is low, the electric heated kang of the common coal-fired firewood-burning heated kang of some farmers cannot be guaranteed, and the cost of the water heated kang and the like popularized in the current market is generally higher than that of the traditional heated kang, so that the farmers cannot bear the cost. The straw is used as common fuel in farmers, the cost is low, and if the smoke dust generated after the straw is burnt can be treated, the environment is prevented from being damaged, so that the straw is a good fuel. Meanwhile, China is a large food country, the yield of straws is very high, and the government highly pays attention to the comprehensive utilization of the straws. According to statistics, the yield of the black dragon river province in 2018 is about 1.3 hundred million tons, the annual utilization amount is 6825 million tons, and the utilization rate is 64.1%. The straw is used as main fuel, which helps to improve the utilization rate of the straw and simultaneously reduces the work of open-air burning of the straw. The natural gas can be used as an auxiliary fuel of a novel water heating kang as a fuel which can be used by every family, and becomes a heat source mode together with the straw. The basic electric heating water heating kang is further developed to be a novel water heating kang mainly supplying heat by virtue of straws and secondarily supplying heat by virtue of a natural gas water heater and the like, waste smoke dust generated after straw burning is collected, the pollution to the natural environment is greatly reduced, and the waste to resources is reduced.
