Semisynthesis organic heat carrier type coal dust furnace

Abstract

The invention discloses a semisynthesis organic heat carrier type coal dust furnace. The semisynthesis organic heat carrier type coal dust furnace comprises a furnace body. A coal feeding machine is connected to the left side of the furnace body. A pulverizer is connected to the left side of the coal feeding machine. An air blower is connected to the bottom of the furnace body. The furnace body isinternally of a cavity structure. An ignition layer is mounted on the lower portion of the furnace body. A partition plate A is arranged above the ignition layer and uniformly provided with multiplesmall holes A. A combustion chamber is mounted on the small holes. An exchange chamber is arranged at the outer side of the combustion chamber. A partition plate B is mounted above the combustion chamber and provided with small holes B, wherein the small holes B and the small holes A correspond in position and are the same in number. An exhaust air chamber is arranged above the partition plate B and connected with an exhaust pipe A. The exhaust pipe is connected with SCR equipment. The SCR equipment is connected with an exhaust pipe B. The exhaust pipe A is surrounded by a heat exchange pipe A. The heat exchange pipe A is connected with the exchange chamber through a pipe. The other side of the exchange chamber is provided with an outlet. The outlet is connected with a water pump. The water pump is connected with the other end of the heat exchange pipe A through a pipe. By means of the semisynthesis organic heat carrier type coal dust furnace, environmental pollution can be greatly reduced, and quite high popularization performance is achieved.

Description

technical field [0001] The invention relates to a stove, in particular to a semi-synthetic organic heat carrier type coal dust stove. Background technique [0002] The pulverized coal furnace is a boiler equipment that uses pulverized coal as fuel. It has the advantages of rapid and complete combustion, large capacity, high efficiency, adaptability to a wide range of coal types, and easy control and adjustment. The combustion characteristic of the pulverized coal furnace is that the fuel enters the combustion chamber with the air and burns in a suspended state. The coal is pre-ground into very fine pulverized coal, and the contact surface area with the air is greatly increased, which intensifies the combustion. The temperature in the pulverized coal furnace is also high. Therefore, except for the coal with poor coal quality, all kinds of coal can be effectively burned in the pulverized coal furnace, and the combustion is relatively complete and the combustion efficiency is...

Problems solved by technology

[0003] The present invention aims to solve the above problems. By using SCR equipment, the exhaust gas treatment effect can be effectively improved, and the use of SCR equipment can effectively reduce PM2.5 to within the emission standard in a closed environment, so that the environmental pollution problem is greatly alleviated. By using a semi-synthetic organic heat carrier, heat energy can be effectively transferred out without wasting energy, and it will not cause scale accumulation, which is convenient for later maintenance, and using a semi-synthetic organic heat carrier can obtain a higher temperature, which is suitable for The range is wider, and the use of heat exchange tube A can reduce the exhaust gas temperature and greatly improve the heat utilization rate
