Abstract

The utility model provides an environmental protection coal gas energy saving furnace, including a furnace body for entrance and exit provided on the furnace, a fire grate which is arranged at the bottom of the furnace body and an ash cabin with an inlet and an outlet. The utility model is characterized in that the furnace body of the upper fire grate is provided with a feed wind pipe communicated with a fan, the coal gas exit of the furnace body is connected with a coal gas purifier by a coal gas pipe, the smoke exit of the furnace body is connected with a smoke filter by an exhaust pipe. The coal in the furnace can be fully burned so as to increase the gas production and save the coal consumption; the removal of the coal tar, cinder and water vapor in the coal gas can purify the coal gas and effectively increase the caloric value of the coal gas as well as solve the clogging problem of the coal tar; the utility model improves the removal dust efficiency, and removes poisonous gases such as sulfur and carbon monoxide in the smoke. Therefore the utility model is favor of environmental protection.

Description

Environmental protection gas energy-saving stove

Technical field

The utility model relates to a kind of gas furnace, especially a kind of gas furnace of environmental protection and energy saving.

Background technology

With the vapourizing furnace coal that burns, form the technology of semi-water gas again through vaporization, though have historical for many years, but with existing vapourizing furnace burning brown coal and make it to produce the technology of water-gas, so far all not by wide popularization and application, its major cause is: when semi-water gas forms, a large amount of coal tar will be produced, water vapour and other residual gass, not only easy blocking pipe, and also the slagging scorification of incomplete combustion is more, coal gas combustion value is not high, firepower is little, goes back sulfur-bearing, the gas cleaning deficiency, the dust that flue gas is carried secretly is more, irritating smell is denseer, uses, inconvenient operation or the like.Therefore, be necessary prior art is improved.

Summary of the invention

For overcoming the coal tar blocking pipe that prior art exists, the coal gas combustion value of bringing because of coal gas, clean lack is low, the sulfur-bearing height, and deficiencies such as contaminate environment, the utility model provides a kind of environmental protection gas energy-saving stove.

The utility model is realized by following technical proposal: a kind of environmental protection gas energy-saving stove, comprise the body of heater which is provided with import and export, the grey storehouse of being located at the fire grate of body of heater bottom and bringing into, export, the body of heater that it is characterized in that the fire grate top is provided with the air feed pipe that is communicated with blower fan, gas exit on the body of heater links to each other with gas purifier by gas pipe, and the exhanst gas outlet on the body of heater links to each other with smoke filter by smoke exhaust pipe.

Air feed pipe on the body of heater of described fire grate top is communicated with grey storehouse air feed pipe, and links to each other with blower fan, so as with same blower fan simultaneously to the upper and lower part of fire grate air feed so that allow fire coal on the fire grate pass through to burn complete, thereby the raising efficiency of combustion.

Described smoke filter comprises the housing which is provided with import and export, be located at the spray thrower that is communicated with water-supply pipe on housing top, its top of being located at the spray thrower below is worn-out mouthful, the bottom is provided with the strainer of water conservancy diversion siphunculus, and with housing on advance the smoke-intake pipe that mouth links to each other and extends to strainer below.

Water-supply pipe one end of described smoke filter links to each other with spray thrower, and the other end is communicated with the section of being filled with water of lower housing portion by water pump, so that spray dust's recirculated water is provided.

Described gas purifier comprises the housing which is provided with import and export, is located at the intravital coal gas screen plate of shell, and an end extends to outside the housing, and the other end places the thrust-augmenting nozzle of screen plate bottom.

Described body of heater is by outer field furnace shell, the flue of internal layer, and the water jacket of being located between the inside and outside layer constitutes, and is interval with vertical thrust-augmenting nozzle that its upper and lower end all is communicated with water jacket in the water jacket, is used to strengthen cooling performance.

The utility model compared with prior art has following advantage and effect:, make the fully perfect combustion of fire coal in the stove, thereby strengthened gas production rate to the scheme of fire grate upper and lower part air feed by simultaneously, saved coal-fired consumption; By the setting of gas purifier, effectively remove coal tar, cinder, water vapor in the coal gas again, can not only improve coal gas purity and calorific value, but also solved the coal tar blocking problem; By the setting of smoke filter, improve flue gas ash removal efficient, also remove obnoxious flavoures such as sulphur in the flue gas, carbon monoxide simultaneously, help environmental protection.
